Overview

Media Center provides a simple programming language that enhances and enriches its overall user interface and usability. This language, commonly called the expression language, is simple to learn, simple to use, and can greatly enhance your experience using Media Center.

Expressions are ubiquitous throughout Media Center, used in areas such as:

  • The categories in a view
  • File list expression columns
  • Theater View
  • Customized view headers, grouping and sort criteria
  • The library field manager (fields with data type Calculated data)
  • File and folder location definitions
  • Auto-import rules
  • Custom DLNA titles
  • The player's display
  • Captions and thumbnail text
  • The link manager (expressions help format link URLs)
  • Rename, Move, & Copy tool
  • Tag assignment
  • Complex search queries

The Expression Language

An expression is a mixture of ordinary text, pre-defined functions, and a few reserved characters and constructs that have special meaning. An expression is evaluated by Media Center's expression engine and textual output is produced. This output is then used by Media Center to customize the user interface and affect its method of operation.

The Anatomy of an Expression

As mentioned above, an expression is a mixture of text and function calls (and some reserved stuff described shortly). The simplest expression would be some basic, literal text, such as A good movie. The expression engine evaluates this expression, finds nothing special, and then outputs the result: A good movie. Simple.

But simple text only has so much utility. The ability to transform or generate content is much more interesting and useful. And this is when functions are employed. Media Center provides many functions, which when called, produce some output. Most functions require some form of input, called arguments, and most functions generate output. By supplying a function with various arguments, the function will return some output value which is just more text. And this output text can be the used by other functions, and so on. Each function has a unique name, and calling upon a function to do some work requires little more that using its name anywhere in the expression.

A function call looks like this:

functionname(argument 1, argument 2, ...)

The syntax of the function call is the function's case-insensitive name, immediately followed by an opening parenthesis character, one or more comma-separated arguments, and a closing parenthesis character. Whitespace after the commas is optional, but helps readability and formatting. And each argument itself is also just an expression. And some arguments are optional. If an argument is optional, it can be omitted and its default value will be used. If the argument is omitted, a comma-separator will still be required if additional arguments follow. The following example uses the FixCase() function to change its input to Title Case:

fixcase(A good movie)

The result is A Good Movie.

A slightly more complex expression example consists of both text and a nested function call:

Wow! fixcase(replace(A good movie, good, great))

Inner functions are called before outer functions, so the Replace() function is call first:

replace(A good movie, good, great)

and its output is then supplied as the input to the FixCase() function. Replace() does its work substituting good with great, and returns A great movie. This output is then supplied as the argument to FixCase() which sees only the text A great movie (it knows nothing about how it was produced). So the function call:

fixcase(A great movie)

in turn outputs A Great Movie. Now that the functions have produced their output, the final output, including the literal Wow! leading text is

Wow! A Great Movie

Fields

The expression examples thus far have been limited to static literal text. Expressions have much more utility when they use data from other sources, such as a file's metadata. Media Center maintains this metadata in its defined fields. This data is accessed using the Field() function, and its first argument is the case-insensitive name of the field to be accessed. For example, the function call field(album) will return the current* file's value for the album field (* more will be said later about the current file). If the album field contained the value After Hours, the expression:

fixcase(field(album), 3)

would produce AFTER HOURS. First field(album) is evaluated, returning After Hours. The FixCase() function is supplied with this output as its first argument, and its second argument is 3, which happens to specify that it should perform upper-casing.

Because fields are so frequently used in expressions, an abbreviated form exists for accessing their values. This makes it easier to both read and write expressions. Nonetheless, both forms are equivalent. The abbreviated form is simple: immediately surround the field's name with opening and closing square brackets, for example, [album]. The previous example is now written more simply as:

fixcase([album], 3)

Field Values

For the sake of simplicity and clarity, the section above glossed over an important detail regarding how Media Center outputs field values. Recall that Field() is the function used to return the value of a specified field. But Field() also has a second argument that indicates the format of the value that it returns. Because field values are used in a variety of situations, the Field() function can produce output suitably formatted for the requirements. There are two forms of output: one is a nice, friendly human-readable format suitable for use in views or other display locations; the other is a raw format which returns the representation stored internally by Media Center which is useful when uninterpreted values are necessary.

By default, Media Center always outputs the friendly format, so expressions sometimes need to take this into account and chose the format accordingly.

Not used earlier because it is optional, the second argument to the Field() function selects the mode of output: the value 0 selects the raw mode, and the default value of 1 selects the friendly mode. Here are two examples using the date field, the first one outputs the date value in raw format, the second in the friendly format:

field(date, 0)
field(date, 1)

Field Values: Empty, 0, and 1

The Media Center expression language does not strongly differentiate between the numeric value zero 0 and emptiness for numeric field types Integer and Decimal. And in some cases, the numeric value of 1 is treated similarly to the empty value.

When a value of 0 is entered as a numeric field's value, the raw value will be shown as 0, but the display format (as in the file list) will be shown as empty. The empty display allows for less visual noise in the user interface, since a column full of 0 values is not usually helpful. In fact, if you attempt to set a numeric field's value to 0 in the file list, it will immediately be displayed as empty.

Generally this difference is unimportant, except when testing numeric values with IsEmpty() or IsEqual(). It is easy to be fooled when testing such a value if the value shown in a file list is empty. The values shown in the Tag Action Window will reveal the actual raw value, as will an expression column using the field's raw format.

Another consideration for integer fields is that when sorting, a 1 value can sometimes sort indistinguishably from an empty value. The Integer type disc # field is typically empty when an album consists of only one disc, and as such, Media Center will sort the disc # values of empty and 1 identically.

The friendly output of a field can differ, depending on context. For example, in a file list, and empty field will be shown as blank, but in the Rename, Move & Copy tool, it will be output as Unknown Disc # (this ensures no blank values are generated as path components). To test such a field, always use and test against the raw format, and then expressions will be context agnostic.

Expression Language Syntax

Now that the basics have been covered, the more rigorous rules of the expression language syntax can be described.

  • An expression is any sequence of literal text and any number of function calls.
  • Expressions are read and evaluated left to right. Literal text is output unmodified, function calls are evaluated and their return values output.
  • Nested functions calls are evaluated from the innermost function to outermost function, and again, left to right when one function follows another.
  • Field abbreviations are expanded into the equivalent Field() function call
  • A functions is evaluated and its returned value contextually replaces the function call in the expression
  • Within a function's argument list, whitespace is ignored before and after commas, after an opening parenthesis, and before a closing parenthesis.
  • The forward-slash escape character / disables the special meaning of the character that follows it.
  • The escape sequence /# followed by #/ escapes everything inside.
  • To use a literal parenthesis, comma, or whitespace inside of function argument lists, escape them. Whitespace within an argument's value is literal and does not need to be escaped when it is surrounded by other non-whitespace text.
  • An expression may be split into multiple lines, but when it does not satisfy the conditions above regarding whitespace around function parenthesis and commas, use a forward-slash escape as the last character before the newline. Extraneous newlines in the expression editor will produce a trailing ellipsis (...) in the output.

Expression Editors

There are a couple of variations of dialog or edit field used to enter expressions. Some allow multi-line expressions, while others are single line, but can be expanded to multi-line editors. Unfortunately, some single-line editors flatten multi-line expressions into a single line, replacing the newlines with spaces. This author is hopeful this will be rectified someday.

How Expressions Are Evaluated

Expressions are evaluated in the context where they are used. For example, an expression column in a file list is evaluated relative to those files in the file list. And the general flow is that for each file in the list, the expression is evaluated and produces output. The expression only has access to the fields available for the file currently being evaluated. This is important to remember, so it bears repeating. One file after another, an expression is evaluated against that single file, its output is produced and stored away for use later, and then the result of that evaluation is entirely forgotten before the next file is evaluated. This means, the expression evaluator cannot use the results from one file's evaluated expression with the results of another file's evaluation.

Expressions and Locales

Media Center will respect the Windows locale setting for output values produced by certain functions, and within the values of certain fields. This is important to consider when writing expressions that consume such values. Under most circumstances, such values cause no harm. However special care must be taken with functions that require the use of period as the decimal point. One such function is Math(), which always uses period as the decimal point. If your locale uses some other character such as comma, these characters will have to be converted into periods before the critical function is called. Handling this problem is not difficult. Before passing to Math() any floating point number, use Replace() first when necessary to convert the locale's decimal character into a period. Fields that cause problems are any fields that produce floating-point values, such as any Date type field in raw format (e.g. [date,0], [last played,0], [date modified,0], and [date imported,0]), or any textual field that contains floating-point values that will be used for various calculations (e.g. any of the Dynamic Range variants). Certain functions such as Now() and ConvertTime() also return localized floating-point values. Consider also that the expression parser uses comma as the argument separator. Any literal numeric values specified as a function argument must have any embedded commas escaped.

A Complex Expression Example

Expression Editor.png

Here is a more complex expression example that illustrates the various rules discussed above regarding expressions:

if( IsEmpty( [Disc #] ),
Disc number is empty,
Delimit(
field(disc #) ,
/) ,
DISC /(
)
)

The expression demonstrates that

  • whitespace before and after commas or opening and closing parenthesis is ignored
  • expressions can be safely split into multiple lines using the whitespace rules just mentioned
  • function and field names are case insensitive
  • forward slash is used and required to escape parenthesis (see inside the Delimit() function)
  • whitespace does not require escapement when surrounded by other characters (see after the C in DISC)
  • literal text is output unmodified (Disc number is empty)
  • functions can be nested (Both IsEmpty() and Delimit() are nested within the If() function, and the Field() function is nested within Delimit()

When the expression is run, files that have no disc number will produce Disc number is empty, and files that have, say, a disc number value of 3 will produce DISC (3).

Field Assignment

The output of an expression can be used to assign a value to a tag. This is accomplished by preceding the expression with an = character. The = character causes the tagging engine to invoke the expression evaluator first, and then to use its output as the value to assign to the field.

Field Assignment with Expression.png

Without the prepended = character, the literal expression text itself and not its evaluated value would be stored in the tag. The expression can refer to the field's own value to modify itself, and this offers a convenient way to perform complex transformations on field values. For example, the assignment expression

=removeleft([name], 4)

entered into an edit cell for the name field would remove four characters from the left of the name field's current value. An assignment expression can be entered into the Tag Action Window, or by using inline editing in the file list or a pane entry. The image on the right shows in-place field assignment.

Note: Undo is supported, reverting each tag to its value prior to the assignment. Redo is also supported, reapplying the most recent Undo.

Expressions and Search

The expression language is fully available to the search query engine (Search, Set rules for file display, etc.). This allows creation of more complex search queries than would otherwise be possible. An expression-based search query is any valid expression that produces a zero or non-zero numeric output. The syntax of the query is:

[=expression]=numval

where expression is any valid expression, and numval is the expected numeric output produced by the expression. The expression is evaluated against the current list of available files and the expression output numerically compared against numval. All files for which the comparison is true are returned as part of the file list produced by the query and all files that fail the comparison are winnowed from the file list.

The following example illustrates an expression-based search query:

[=ismissing([filename (path)]\Folder.jpg)]=1

The IsMissing() function is run using the file name argument [filename (path)] appended by \Folder.jpg, and returns a Boolean value 1 for files that are missing, and this 1 is compared against the value numval. All these files where there was a successful comparison are returned in the file list, and all those for which the expression produced 0 are filtered from the file list. By inverting the comparison and using a 0 numval, the set of files remaining in the file list would be those that did not match.

Data Types

It was mentioned already that the Media Center expression language is primarily a textual language - it consumes and produces text. Nonetheless, certain areas of Media Center are influenced by the type of data used or presented, and sometimes it is useful or necessary to coerce expression output into one data type or another. Each Media Center field is defined to be of a certain data type, listed in the Field Data Types table. These types influence how values are output, sorted, and interpreted on input. And expressions always output data of type String. By coercing the data type of an expression, output formatting and sorting can be controlled in various ways.

Data types are forced by appending to an expression the string:

&datatype=[type]

where type is one of the following values:

listA list of strings, separated by semicolons
stringSorts as strings (with smart number handling)
numberSorts values as numbers (decimal or integer)
integerSorts values as integers
pathSorts using a smart filename compare style
monthSorts string month names (i.e. January, February, etc.)

Calculated Fields and Search

Media Center's Search supports some simple numeric comparison operators. Because expressions always evaluate as a String type, these operators would be unavailable for use in a search query to compare numeric values from a calculated expression field. In order to use the numeric comparison operators, a calculated expression field can be cast into one of the numeric types. In your numeric calculated fields, to allow the use Search's numeric comparison operators, add either of the casts:

&datatype=[integer]
&datatype=[number]

to the end of the field's calculated expression.

Lists and Trees

Datatype List.png

The list of output in view categories and pane columns can be modified by forcing the data type to a List type. Two things happen when the data type is List: The values within a List type are split into their individual (semicolon-separated) list items The backslash character takes on a special meaning and becomes another form of separator that creates tree-like hierarchies, collapsible in panes columns and creates drill-down categories in any category view type (Standard View > Categories, Theater View, DLNA, Gizmo/WebGizmo). Forcing an expression's type to list causes this list item separation and hierarchy generation. Alternatively, forcing a List type to string defeats this. Add the cast:

&datatype=[list]

to the end of an expression to force an expression's output to be considered as a List type. Conversely, a List type may be forced into a String type by adding the cast:

&datatype=[string]

to the end of an expression.

Sort Order

Datatype Month.png

Normally strings are sorted ASCII-betically with some smart numeric sorting. But this form of sort may not always be desired.

Sorting by Month

Generally it is more useful to see month names sorting such that January sorts before April, instead of alphabetically where April would sort before January. Forcing an expression's type to Month forces string month values to be treated instead as their equivalent numerical month numbers. For example, the first month January and the third month March sort before the fourth month April. Add the cast:

&datatype=[month]

to the end of an expression to force an expression's output to be sorted by numeric month values.

Sorting by Path

Path data types sort using smart filename comparisons.

XXX: Note: This section is incomplete. I cannot distingish any difference between using a datatype of path vs. string. It seems path sort order is always engaged.

Add the cast:

&datatype=[path]

to the end of an expression to force an expression's output to be smart-sorted by path components.

Functions

Accessing and Storing Functions

The functions in this section access field values, store and load global variables, access file tags, and access note fields.

Field(…): Returns a field's value

Description field(name, mode)

The Field() function returns the value stored in field name. The format of return is selected by mode.

Available mode values:

0Raw, unformatted data
1Formatted data

Argument mode is optional (defaults to 1).

Examples field(album)

Returns the formatted value of field name album. Note that this is equivalent to [album].

field(date, 0)

Returns the raw, unformatted value stored in the date field. Note that this is equivalent to [date,0].

Load(…): Outputs the value of a global variable

Description load(varname)

Loads and outputs the value of the specified global variable varname that has been previously stored with Save().

Examples load(var1)

Loads and outputs the previous stored value of the global variable named var1. If var1 has not been previously stored, the output will be empty.

save(math(1 + 2), sum)load(sum)

Saves the output of the Math() function into sum, and then loads and outputs the value of sum, which is 3.

Note(…): Retrieve note fields

Description note(field label, field type, occurrence)

The Note() function retrieves information from a Media Center Note. Specifically, it returns the contents associated with a field label, of a given field type. The Nth occurrence may be requested. Notes data may be simple text, or associated with defined a field label. Currently the only type of field label is contact information. The first line of a Note is associated with the omnipresent field label Name.

The field type selects the specific sub-type for a given field label, and occurrence selects which instance of several field label / field type pairs is returned. The occurrence value is zero-based.

Argument field type is optional (defaults to FIRST AVAILABLE).

Argument occurrence is optional (defaults to 0).

Examples note(phone)

Returns the value found in the first Phone field label. If no Phone label exists, nothing is returned.

note(phone, home)

Returns the value found in the first Home field type from the Phone field label. If the Phone label, Home type does not exists, nothing is returned.

note(phone, home, 1)

Same as the previous example, but the second instance of the field type is selected instead of the first, since occurrence is zero-based.

Save(…): Saves a value to a global variable

Description save(value, variable, mode)

This Save() function saves the value into the specified global variable, and optionally will return that value if mode is set. Once a global variable has been created using Save(), that variable's value is available for use with either Load() or the pseudo-field "[variable]".

0Suppress output
1Output variables value

Argument mode is optional (defaults to 0).

Examples save(Much Money, local_bank)

Saves the value Much Money into the global variable local_bank.

save(More Money, My Bank, 1)

Saves More Money into My Bank and outputs the variables value More Money.

save(math([duration,0] / 60), durmins)if(compare([durmins], >, 5.0), Long Track, Short Track)

Saves the calculated duration in minutes into the variable durmins. Notice that subsequent expressions fragments such as the if(compare()...) may now use the pseudo-field [durmins] as shorthand for load(durmins).

Additional Examples

Generating statistics
Generating album track count
Generating album ratings
Highlighting playing album

SaveAdd(…): Adds to a global variable

Description saveadd(variable, value, mode)

The SaveAdd() function adds value to a global variable either numerically or as a list item. The mode argument indicates how variable is modified.

Available mode values:

0Add numeric value (integer or decimal) to variable
1Append string value as a list item to variable
2Prepend string value as a list item to variable

Argument mode is optional (defaults to 0).

Examples saveadd(v, 1)

Numerically increments the global variable v by 1.

saveadd(v, math(2 - 6))

Numerically increments the global variable v by the outcome of the Math(), which is -4.

load(foo, v)saveadd(v, bar, 1)load(v)

Loads value foo into variable v, then appends the value bar as a list item, and the final load(v) expression outputs the result of foo; bar.

load(That, v)saveadd(v, This, 2)load(v)

Similar to the previous example, but using the prepend mode, resulting in the output This; That.

Tag(…): Returns a file's physical tag

Description tag(tag name)

The Tag() function reads and returns the value of tag name directly from a file. The Media Center Library database is not used with Tag(), and instead the specified file is read for the requested tag. The spelling and letter case of the tag name must match exactly those stored in the file. Performance note: This function must open and read the actual file, so its performance is significantly slower than other functions which operate on database fields.

Examples tag(My Personal Tag)

This will return the value from the tag named My Personal Tag from file referenced by the [filename] field.

tag(Gapless Header)

Returns the Gapless Header tag value, often contained in an mp3 file.

tag(exif: Date)

Returns the raw date data from the EXIF data saved inside a jpg file.

Conditional Functions

The functions in this section test one or more arguments to produce either a true or false outcome, and execute specific actions depending upon that result.

The expression language does not directly support AND, OR, and XOR operations. However, these can be easily emulated using any of several techniques. See: Database_Expressions_AND_OR_And_XOR.

The NOT operator ! (exclamation point) may be used in a conditional to invert the sense of the conditional test. Inverting the sense of a test can make reading expressions easier, or support better IfElse() sequences.

If(…): Conditional if-else evaluator

Description if(test expression, true expression, false expression)

The If() function is used to evaluate a test expression, and will output the result of the true expression or false expression, depending upon the evaluation result. The test expression is expected to return a 0 (false value) or a non-zero (true value). Nesting is allowed. If the test expression is preceded by the NOT operator (!, an exclamation point), the sense of the test is inverted. Non-zero values are inverted to 0, and 0 is inverted to 1.

Examples if(isequal([artist], bob dylan, 1), Genius, Mediocre)

Outputs Genius when artist is (case insensitive) Bob Dylan and Mediocre otherwise.

if(isequal([artist], bob dylan, 1), Genius, if(isequal([album], Joshua Tree, 8), Great Album, Mediocre))

This nested If() expression expands on the previous example, by first evaluating if the artist is Bob Dylan, and outputs Genius if true. When the artist is not Bob Dylan, the album is then tested to see if it is Joshua Tree, and if so outputs Great Album, otherwise outputs Mediocre.

if(!isempty([comment]), regex([comment], /#^(\\S+\\s+\\S+\\s+\\S+)#/, 1), *No Comment)

Output's the first three words of the comment field; otherwise, outputs *No Comment. By using the NOT operator, the sense of the conditional is inverted so that the more interesting case is moved ahead of the more mundane case.

IfElse(…): Conditional if-elseif evaluator

Description ifelse(test1, action1, test2, action2, test3, action3, )

The IfElse() conditional provides a convenient mechanism for shortening and more clearly expressing nested conditionals into an alternating sequence of tests and actions. One or more test/action pairs may be specified.

For example, consider a nested sequence of If() tests such as the following pseudo-code:

if (test1)
action1
else if (test2)
action2
else if (test3)
action3

The IfElse() statement may be used to more cleanly express the flow of expression by removing the superfluous internal If() statements, converting the clumsy expression:

if(test1, action1, if(test2, action2, if(test3, action3)))

into the more elegant:

ifelse(test1, action1, test2, action2, test3, action3)

If any of the test expressions test1, etc. are preceded by the NOT operator (!, an exclamation point), the sense of that test is inverted. Non-zero values are inverted to 0, and 0 is inverted to 1.

Examples ifelse(isequal([media type], Audio), Le Tunes, isequal([media type], Video]), Flix)

If media type is audio, outputs Le Tunes, else if media type is video, outputs Flix

ifelse(isequal([artist], Bob Dylan), Genius, isequal([album], Joshua Tree, 8), Great Album, 1, Mediocre)

This example, implements the nested if statements from the If() section above, first testing if the artist is Bob Dylan, and if true, outputs Genius, otherwise evaluates the second test to determine if the album is Joshua Tree, and if true, outputs Great Album, otherwise, performs a final test, in this case a degenerate test of 1 (and 1 is always true), thus outputting the value Mediocre.

FirstNotEmpty(…): Returns the first non-empty argument

Description firstnotempty(value1, value2, )

The FirstNotEmpty() function acts as a conditional by returning the first argument from value1, value2, ... that is not empty. Two or more arguments may be used, and the first non-empty argument is returned. With two arguments, is is functionally equivalent to the sequence such as if(!isempty(value1), value1, value2). With more than two arguments, FirstNotEmpty() avoids long nested If() sequences that simply test for emptiness.

Examples firstnotempty([media sub type], Misc Video)

Returns the value in media sub type if it is not empty, otherwise returns Music Video.

firstnotempty([series], [name], Tag your Videos!)

Returns the first non-empty value from the fields series or name, and if both are empty, returns the reminder to Tag your Videos!.

Test and Comparison Functions

The functions in this section return a Boolean value of either 1 (true) or 0 (false). They are generally used to drive an action specified in one of the Conditional Functions.

Compare(…): Compares two numbers

Description compare(value1, operator, value2)

The Compare() function compares two numeric values value1 and value2 using the specified operator.

Available operator values:

=Equivalence
<Less than
<=Less than or equal to
>Greater than
>=Greater than or equal to

Outputs 1 if the comparison is true, and 0 otherwise.

Examples compare([bitrate], <, 320)

Returns 1 when the bit rate is less than 320 (Kbps), and 0 otherwise.

if(compare(math(now() - [date modified, 0]), >, 21), Expired, formatdate([date modified, 0], elapsed))

Outputs the age of files under 21 days old, or Expired for older files.

IsEqual(…): Compares two values in one of nine specified modes

Description isequal(value1, value2, mode)

The IsEqual() function compares value1 with value2 using any mode from the list of modes below. Outputs 1 when the comparison succeeds according to the mode, and 0 otherwise. Although the mode is specified as the last argument, the comparison should be mentally read as: value1 mode value2.

Available mode values:

0Case-sensitive string compare for equality
1Case-insensitive string compare for equality
2Numeric compare for equality
3Numeric less than
4Numeric less than or equal to
5Numeric greater than
6Numeric greater than or equal to
7Substring search (case sensitive)
8Substring search (case insensitive)

Argument mode is optional (defaults to 0).

Examples isequal([artist], [album], 1)

If the artist and album values are the same, the output will be 1, otherwise, the output will be 0.

if(isequal([artist], [album], 1), Eponymous, [album])

The If() function basis its decision on the outcome of IsEqual(), so if the artist and album values are the same, the output will be Eponymous, otherwise, the output will be the value of album.

if(isequal([artist], [album], 1), Eponymous/,, [album]/))

This example demonstrates the character escaping mentioned in the overview earlier. Here, we want the output to be either Eponymous, (note the inclusion of the comma) or the album value with a closing parenthesis. In order to achieve this, the comma, and the closing parenthesis, are escaped using a forward-slash character. This informs the expression evaluator that these characters are not part of the expression syntax and are to be treated literally.

if(isequal([filename (path)], classical, 8), Classical, Not Classical)

Because compare mode 8 has been specified, if the word classical appears anywhere in the case-insensitive file path, the expression will return Classical, and if not it will return Not Classical.

IsEmpty(…): Tests a value for emptiness

Description isempty(value, mode)

The IsEmpty() function tests the given value for emptiness. The value passed is typically an Media Center field, so that some action may be taken when the field is or is not empty. Returns 1 when the value is empty, otherwise 0.

Available mode values:

0String test (field must be empty to get a positive result)
1Numerical test (field must be empty, or contain 0 to get a positive result)

Note that Media Center does not discriminate between a 0 value and an empty value for fields of type Integer and Decimal - both 0 and empty are considered equivalent for these field types. This is useful for fields such as the integer field Disc #, where an empty or 0 value implies that Disc # contains no useful data, and should be generally ignored or absent in display output.

Pay particular attention to the third example offered below, as it covers a caveat that comes with this particular function.

Argument mode is optional (defaults to 0).

Examples isempty([comment], 0)

If the comment field is empty, IsEmpty() returns 1, otherwise 0.

isempty([track #], 1)

Performs a numerical test for data in the [track #] field. If the field is empty or 0, a 1 is returned, otherwise 0 is returned.

ifelse(!isempty([disc #]), [disc #])

Outputs the value of the disc # field when it is not empty.

IsRange(…): Tests a value for inclusion within a given range

Description isrange(value, range)

The IsRange() function tests if a value falls within a given range of values. If the value falls within the given range, 1 is returned, otherwise 0 is returned.

A range is specified in the form of low-high, where low and high are either letters or numbers. The lowest value comes first, the highest second. Both low and high must be the same kind (letters or numbers). The low and high values are inclusive.

Some Example Ranges:

1-100
a-z
c-d
23-7542
Examples isrange([artist], a-c)

Artist values of Abba or Blondie will result in a 1, but ZZ Top will return a 0.

if(isrange([bitrate], 96-191), Poor Quality, High Quality)

Returns Poor Quality for any file whose bit rate falls in the range of 96 to 191, and returns High Quality for all other bit rates.

Additional Examples

Using IsRange() in a Search List.

IsMissing(…): Tests to see if a file exists on the system

Description ismissing(filepath)

The IsMissing() function tests for the existence of a file in the file system. If the file is missing, the function returns 1, otherwise 0 is returned if the file exists. This function is useful for checking for missing files in a Library. IsMissing() treats special entries such as ripped Blu-ray or DVDs as single files, even though they physically exist in the file system as several files and directories.

Note: Any view or list that uses IsMissing() will be slow, is Media Center must interrogate each referenced file in the file system. The larger the number of files being queried, the longer it will take to produce results. Use IsMissing() with care.

Argument filepath is optional (defaults to [filename]).

Examples ismissing()

If the referenced file was not found in the file system, 1 is returned; otherwise 0 is returned.

ismissing(C:\Music\My Lost File.mp3)

Checks for My Lost File.mp3 and returns 1 (positive) if the file does not exist, and 0 (negative) if the file does exist.

if(ismissing(), File is missing, File exists)

Outputs File is missing or File Exists depending on the result returned by IsMissing().

[=ismissing([filename])]=1

This example demonstrates how to construct an expression for use as a Media Center search query. If you place this in the search field in the top right corner of the program while viewing all of your library, it will filter the list, leaving only the missing files on view. If all files in library exist, this list will be empty. You could also create a view scheme and use this string in the Set rules for file display search to give you a view that you can visit periodically to check that your library is not missing any files.

IsRemovable(…): Tests to see if a file is stored on removable media

Description isremovable(filepath)

The IsRemovable() function tests if a file resides on removable media and if so, returns 1, and if not, returns 0. The Media Center field [Removable] also provides the same value for a given file.

Argument filepath is optional (defaults to [filename]).

Examples isremovable()

Checks if the current file is on removable storage, and if so, returns 1, otherwise returns 0.

IsInPlayingNow(…): Tests to see if a file is in the Playing Now playlist

Description isinplayingnow(filepath)

The IsInPlayingNow() function tests if a file is in any zone's Playing Now list. Used as an expression category, pane or file list column allows distinguishing files that are in the Playing Now list.

Argument filepath is optional (defaults to [filename]).

Examples isinplayingnow()

If the file in the Playing Now list, returns 1, otherwise returns 0.

if(isinplayingnow(), Queued, Not queued)

If the file in the Playing Now list, returns Queued, otherwise Not queued.

Additional Examples

IsPlaying(…): Tests to see if a file is in currently being played

Description isplaying(filepath)

The IsPlaying() function tests if a file is playing in any zone. Used as an expression category, pane or file list column allows distinguishing files that are playing now.

Argument filepath is optional (defaults to [filename]).

Examples ifelse(isplaying(), <font color="ff0000">♪<//font>, isinplayingnow(), ♪)

This expression in a file list expression column shows which files are in the Playing Now list and which are currently playing by outputting a musical note in the column. The musical note will be displayed in red for any currently playing file.

Formatting Functions

The functions in this section format their arguments in specific ways. Some functions are used for formatting values for better presentation, or according to some format, while other functions work on Media Center internal "raw" data to convert to user-friendly formats.

Certain Media Center fields are used to store values in ways that are internally convenient or efficient. But these field values are not terribly useful or meaningful when used directly.

For example, the Duration field holds values as a number seconds of length, while various Date/Time fields such as Date or Last Played store values as floating point numbers specifying a number of days and fractions of a day since a particular epoch time.

Media Center will generally format fields using the "display" format where necessary, such as in panes, file list columns, or various tools such as the Rename, Move & Copy tool. When a function requires a raw field value, or you want to access a raw field value, by sure to use the raw field format. This is done by appending a ,0 to the field's name inside the brackets, for example [Date Imported,0].

Delimit(…): Outputs a value with head/tail strings when value is non-empty

Description delimit(expression, tail, head)

The Delimit() function outputs the value of expression prepended with a head string and/or appended with a tail string, but only if the value of the expression is non-empty. Nothing is output when the expression evaluates to empty.

Argument tail is optional (defaults to SPACE).

Argument head is optional (defaults to EMPTY).

Examples delimit([Track #], .)

Appends a period after a track number if [Track #] is not empty, such as 12..

delimit([Date (year)], {, })

Outputs the year surrounded by curly braces, for example {2012}.

FormatBoolean(…): Formats a boolean (true / false) value in a specified manner

Description formatboolean(conditional, true string, false string)

The FormatBoolean() function outputs true string and false string values to represent the 0 or 1 Boolean output resulting from the conditional expression. When the conditional evaluates to 1, the true string will be output, otherwise the false string will be output.

Argument true string is optional (defaults to True).

Argument false string is optional (defaults to False).

Examples formatboolean(isempty([number plays]), Never Played, Has Been Played)

Returns Never Played when the expression IsEmpty() evaluates to 0, and Has Been Played when it evaluates to 1.

formatboolean(math([track #] % 2)

Outputs the default True label for odd track numbers, and the default False label for even ones.

FormatDuration(…): Presents a duration of seconds in a reader friendly format

Description formatduration(duration value)

The FormatDuration() function formats a duration value into a friendly format. The duration value argument is expected to be a value representing a number of seconds, typically used for media file duration. Media Center internally stores duration values in seconds.

Examples formatduration([duration,0])

Outputs a friendly display of the duration field. This is the same output shown using the Duration field in a file list.

formatduration(600)

This will output ten minutes in the format 10:00.

FormatFileSize(…): Presents a number of bytes in a reader friendly format

Description formatfilesize(bytes value)

The FormatFileSize() function formats a bytes value into a friendly format. The bytes value argument is expected to be a value representing a number of bytes, typically used for media file size. Media Center internally stores file size values in bytes. FormatFileSize() will convert those byte values into unitized friendly formats such as 50 bytes, 3.2 KB or 10.4 MB.

Examples formatfilesize([file size,0])

Outputs a friendly format of the file size field. This is the same output shown using the File Size field in a file list.

formatfilesize(56123456)

Outputs the bytes value 56,123,456 as 53.5 MB.

FormatNumber(…): Formats and rounds a number to a specified number of decimal places

Description formatnumber(value, decimal places, label zero, label plural, label singular)

The FormatNumber() function formats a numeric value to a specified number of decimal places, rounding its value, and optionally outputs value-dependent labels, which can be used to construct more grammatically-correct output. The value can be any numeric value. The decimal places argument specifies the number of digits to be used after the decimal point. Use -1 to output as many decimal places as available.

The label selected depends on the original value, not the resulting formatted value.

The label zero argument is output instead of a formatted value when the original value is 0. When this label is specified as empty, label plural is used. The label plural argument is appended to the formatted value when the original value is more than 1. The label singular argument is appended to the formatted value when the original value is equal to 1.

Note: FormatNumber() will not output additional zero's after the decimal point. In other words, FormatNumber() rounds fractional values, but does not zero fill.

Argument decimal places is optional (defaults to 0).

Argument label zero is optional (defaults to label plural).

Argument label plural is optional (defaults to 0).

Argument label singular is optional.

Examples formatnumber([duration,0], 2)

Returns a file's duration (which are in seconds) rounding to two decimal places.

formatnumber([number plays,0], 0, Unplayed, Plays, Play)

Outputs values in whole number formats (no decimals shown). When the number of plays is 0, the output will be Unplayed. When it is more than one, such as six, outputs 6 Plays. And when the number of plays is one, outputs 1 Play.

formatnumber([number plays,0], 0, , Plays, Play)

Same as the previous example, but uses the default value for label zero (which is label plural), so that when number of plays is zero, output is 0 Plays.

formatnumber([number plays,0], , , , Time)

In this example, only label singular argument is specified (as Time), so all other arguments use their defaults values. The output will be 0 when number of plays is zero, 1 Time when number of plays is one, and the actual number of plays for other values (e.g. 6).

FormatRange(…): Formats a value as a range

Description formatrange(value, range size, mode)

The FormatRange() function creates numerical or alphabetic groupings of size range size, and returns the grouping where value falls. Only the first character of value is considered and used. The range size is a numerical value specifying how wide the range should be. Numeric ranges are 0-based. The mode specifies the type of range grouping.

Available mode values:

0Automatically choose between number / letter grouping
1Letter grouping
2Number grouping

Argument range size is optional (defaults to 1).

Argument mode is optional (defaults to 0).

Examples formatrange([artist], 3, 1)

Outputs the range that the artist's first letter falls within. With a range size of 3 and using mode 1 (letter grouping), ranges will be produced in the form of a-c, d-f, g-i, etc.

formatrange([artist])

With range size and mode values left unspecified, default values are used, so automatic range groupings of size 1 are output. Hence, the first character of [artist] will be output.

formatrange([bitrate], 100, 2)

Numeric range groupings of size 100 will be output, for the value of [bitrate]. Possible outputs are: 0-99, 100-199, 200-299, etc.

Additional Examples

How to produce 1-based range values.

Orientation(…): Outputs the orientation of an image

Description orientation()

The Orientation() function outputs one of the following words indicating the orientation of an image file:

PortraitWhen height > width
LandscapeWhen width > height
PortraitWhen height = width
Examples if(isequal(orientation(), Square), Square, Rectangle)

Outputs Square for square images or Rectangle for portrait and landscape images.

PadNumber(…): Adds leading zeros to any given number

Description padnumber(value, number digits)

The PadNumber() function adds leading zeros to any given number value, producing a value of length number digits.

Examples padnumber([track #], 2)

This will pad the track number with leading zeros sufficient to ensure the output is minimally two digits in length.

padnumber(counter(), 4)

Outputs 4 digits of zero-padded numbers produced by Counter(). For example, 0001, 0002, 0003, etc.

RatingStars(…): Outputs the value of Rating as a number of star characters

Description ratingstars()

The RatingStars() function outputs the Rating field's value as the equivalent number of black star characters.

Examples ratingstars()

For a file that has a Rating of 4, outputs ★★★★.

Watched(…): Outputs a formatted video bookmark

Description watched(mode)

The Watched() function outputs a video's bookmark position in a human-readable format, using a specified mode.

Available mode values:

0Output a human-readable watched status.
1Output a numeric watched value (see Watched Status Values below)
2Output a watched checkmark ✓ if watched

Watched Status Values

-1File type is not Video
0Not watched
1Partially watched
2Entirely watched

Argument mode is optional (defaults to 0).

Examples watched()

Outputs formatted watched status, such as 57% on Sep 25, or Aug 21, or nothing when the video has not been watched.

ifelse(compare(watched(1), =, 1), Finish Me, compare(watched(1), =, 2), I'm Done)

Outputs Finish Me if the video has been partially watched, and I'm Done when completely watched.

String Manipulation Functions

The functions in this section are used primarily to manipulate strings. Since the Media Center expression language is primarily string-oriented, these functions provide a means to manipulate field values or the output from other expressions.

Clean(…): Clean a string to be used for various operations

Description clean(string, mode)

The Clean() function is generally used to sanitize a string by stripping empty brackets, remove superfluous dash characters, eliminate leading or trailing articles, or replace filesystem-illegal characters. It is typically employed before some operation such as Rename to clean the product of joining various fields, some of which may be empty, or to produce filesystem-safe filenames. It may be used for a variety of purposes, however.

Available mode values:

0Removes empty () and [], superfluous dash (-) and whitespace characters and sometimes comma (be careful)
1Removes the article 'the' from the beginning and ', the' from the end
2Removes any article (a, an, the, etc.) from the beginning and end
3Replaces each filesystem-illegal character \ / : * ? " < > | with an underscore _, and replaces each unprintable character with a space

Argument mode is optional (defaults to 0).

Examples clean([album] - [date])

The concatenation of [Album] - [Date] may leave a dangling - string when date is empty. Clean() in the default mode removes this dangling string.

clean(The Beatles, 1)

For sorting or grouping purposes, it is often desirable to remove the leading article The from a string. Clean() in mode 1 provides a convenient solution, and in this example produces Beatles.

clean(AC//DC: Back In Black, 3)

When an expression is to be used to produce a filename, filesystem-illegal characters must be removed or converted to legal characters. Clean() in mode 3 will convert such characters into safe underscores. This example would produce the filesystem-safe value of AC_DC_ Back In Black.

clean(\//:*?"<>|, 3)

This trivial example demonstrates how all filesystem-illegal characters are converted to underscores, producing the nine-character output _________ which consists entirely of underscores.

FixCase(…): Changes the case of a given string

Description fixcase(string, mode)

The FixCase() function will convert the supplied text string according to the specified mode.

Available mode values:

0Title Case
1All Words
2First Word
3All Uppercase
4All Lowercase

Argument mode is optional (defaults to 0).

Examples fixcase(enjoy the silence)

The default mode 0 is used, so the output is Enjoy the Silence.

fixcase(enjoy the silence, 1)

Using mode 1, all words are uppercased, so the output is Enjoy The Silence.

fixcase(MY ALbUm IS cAlLeD: adam, 4)

Outputs my album is called: adam.

FixSpacing(…): Intelligently splits adjacent camel-cased words

Description fixspacing(string, mode)

The FixSpacing() function inserts spaces between adjacent camel-cased words in string. It is useful for helping to clean and convert metadata that favors compactness over standard sentence structure.

Available mode values:

0Disables conversion
1Enables camel-case conversion

Argument mode is optional (defaults to 1).

Examples fixspacing(OneWorld)

Outputs One World.

fixspacing([name], 1)

Outputs the name field with any camel-case converted into standard sentence structure. If the value of name was, MiracleOn34thStreet, the output would be Miracle On 34th Street.

fixspacing(Another [name])

Assuming the same [name] as above, this would return Another Miracle On 34th Street.

Hexify(…): Hexifies a string to make it suitable for web usage

Description hexify(string)

The Hexify() function URI encodes a string to make it useable by a browser or search engine. Hexify() is typically used by expressions generating or working on URLs in Media Center's Link Manager.

Examples hexify(Oasis - /(What's The Story/) Morning Glory?)

The result is Oasis%20-%20%28What%27s%20The%20Story%29%20Morning%20Glory%3F.

Left(…): Retrieves a specified number of characters from the left of a string

Description left(string, quantity)

The Left() function retrieves no more than quantity characters from the left of the string.

Examples left([filename], 3)

Return the Windows drive letter, colon and first back-slash from the filename.

Length(…): Returns the number of characters in a string

Description length(string)

The Length() function returns the number of characters contained in string.

Examples length(A Simple Plan)

Returns 13.

if(compare(length([filename]), >=, 68), Long, Short)

The length of the filename is calculated, and compared against 68, outputting Long when the length is greater than or equal to 68, and Short otherwise.

Mid(…): Retrieves specified characters from a string

Description mid(string, start position, quantity)

The Mid() function returns a specified quantity of characters from the start position in string.

The start position is 0-based (i.e. the first character is considered position 0). A quantify of -1 returns all characters from the start positionning to the end of string.

Argument start position is optional (defaults to 0).

Argument quantity is optional (defaults to 1).

Examples mid(12345)

Returns 1, using is the default quantity (1) of characters from the default start position of (0 - the beginning of the string).

mid(12345, 1, 2)

Returns 2 characters beginning at start position 1, which is 23.

Additional Examples

An example that uses Mid() to re-order a date field.
An example that uses Mid() to output a number of stars based on an arbitrary rating value.

Regex(…): Regular expression pattern matching and capture

Description regex(string, regexp, run mode, case sensitivity)

The Regex() function performs regular expression (RE) pattern matching on a string. The string is evaluated against the regular expression regexp, and run mode dictates the values output by Regex(). The three modes allow for match testing, capture output, or silent operation.

All match captures are placed into special variables referenced as [R1], [R2], ... [R9], which can be used in later in the expression. The contents of the captures [R1] ... [R9] are available until the end of the expression, or Regex() is run again, whereby they are replaced. The regular expression implementation used prior to Media Center 19 is the Microsoft 2010 TR1 engine, and in Media Center 19 it is the Boost engine.

Available run mode values:

0Runs in Boolean test mode, returning either a 1 or 0, indicating whether the string matched (1) or did not match (0) the regexp. This run mode is useful within an If() test, so that different true or false actions may be taken.
1 to 9Outputs the specified Nth capture group's contents, where N ranges from 1 to 9. Only a single capture is output in this mode, but all captures are available in the [R1] ... [R9] capture variables. This run mode is used to easily output a single matching sub-string.
-1Runs in silent mode, with no output being produced. This run mode is useful as a means to capture portions of the string to be later used in subsequent portions of an expression.

The case sensitivity argument toggles the case-sensitivity of regular expression matching. Note that case insensitivity does not apply to characters inside a character class [ ]. Use both uppercase and lowercase characters when necessary to match either case (e.g. [aAbB] to match either uppercase or lowercase A or B).

Available case sensitivity values:

0Ignore case when matching (e.g. the letters E and e are identical)
1Consider case when matching (e.g. the letters E and e are considered different)

The regular expression language assigns special meaning to many characters. A few of these meta-characters, such as forward slash /, comma , and both ( and ) are also reserved and used by the Media Center expression language. To force the Media Center expression engine to ignore the meta-characters in regexp, surround the entire regular expression with /# #/. This is one of Media Center's escapements, which tells the expression engine to ignore everything inside, so that the entire, uninterpreted regexp can be provided to the Regex() regular expression evaluator. Although surrounding regexp by /# #/ is not necessary or required when no conflicting characters are in use, and you may manually escape the expression languages meta-characters with a forward slash /, it is probably a safe practice to always encase every regexp within /# #/.

Argument run mode is optional (defaults to 0).

Argument case sensitivity is optional (defaults to 0).

Examples ifelse(regex([name], /#^(the|an|a)\b#/, 0, 1), Fix your case!)

Searches the name field for any of the lowercase articles the, and and a at the beginning of name, and outputs Fix your case! when the match succeeds. The run mode is 0 which is a test and capture mode, and case sensitivity is enabled.

if(regex([artist], /#([[:punct:]])#/, 0), [R1] --> [Artist], No Punctuation)

Using the default mode 0, Regex() will output a Boolean for use inside a conditional to cause some action to occur based on the match success or failure. This example matches against the artist field looking for any punctuation character. If the match succeeds (a punctuation character was found), that character is output followed by the string --> and the artist. In there was no match, the string No Punctuation is output.

regex(D03T02 some track.mp3, /#^D(\d+)T(\d+)#/, 1)Disc: [R1], Track: [R2]

The string is matched against the regexp that is looking for a D followed by any number of digits, followed by a T and then more digits. Those digits were captured, and later used to output the value Disc: 03, Track: 02.

regex([filename (name)], /#^(\d+)-#/, -1)Track number is [R1]

Using run mode -1, the file's name is pattern tested against the regexp which is looking for leading digits followed by a dash. Those digits are captured in buffer [R1] which is used later in the expression. If the file name was 2-foo.mp3, the output would be Track number is 2.

regex([filename], /#(\d{1,2})\.(\d{1,2}).(\d{4})#/, -1)[R3]//[R1]//[R2]

Matches and captures a date formatted as dd.mm.yyyy anywhere within the filename, and rearranges it in a standard format of yyyy/mm/dd. Since run mode is -1, no output occurs. However, captured match segments are made available for subsequent use. The three captures, [R1], [R2] and [R3] are arranged in the textual output so that we get the desired year/month/day ordering, such as 2011/08/19.

RemoveCharacters(…): Removes a list of characters from a string

Description removecharacters(string, character list, mode)

The RemoveCharacters() function will remove from string any characters in the character list. The characters removed depend upon the mode specified. The function operates in a case-sensitive manner.

Available mode values:

0Remove all instances
1Remove from the beginning only
2Remove from the end only
3Remove from each end

Argument mode is optional (defaults to 0).

Examples removecharacters(Paper, Ppr)

Removes P, p, and r from Paper, resulting in ae. The default mode 0 is in effect, removing all instances of the characters specified in the character list.

removecharacters(Paper, Ppr, 1)

With mode 1 set, only the initial character P is removed, resulting in aper.

removecharacters(Paper, Ppr, 2)

In mode 2, only one character from the end of the string are removed, leaving "Pape.

removecharacters(Paper, Ppr, 3)

Both the front and back are affected in mode 3, causing the removal of the leading P and trailing r resulting in ape.

removecharacters([artist], /(/))

Removes any ( and ) characters from anywhere within the [artist] field.

RemoveLeft(…): Trims characters from the beginning of a string

Description removeleft(string, quantity)

The RemoveLeft() function removes a specified quantity of characters from the left side of a string. If the quantity is larger than the length of the string, the output will be empty.

Examples removeleft(Good Deeds, 5)

Removes the first 5 characters from resulting in Deeds being output.

RemoveRight(…): Trims characters from the end of a string

Description removeright(string, quantity)

The RemoveRight() function removes a specified quantity of characters from the right side of a string. If the quantity is larger than the length of the string, the output will be empty.

Examples removeright(03-02-1959,5)

Removes the last 5 characters from the given date, leaving only the month and year 03-02.

Replace(…): Replace or remove a string segment

Description replace(string, old, new)

The Replace() function replaces all instances of old within string with new. If new is unspecified, it defaults to an empty value, causing old to be removed. Replace() operates in a case-sensitive manner.

Argument new is optional (defaults to EMPTY).

Examples replace(The Daily Show with John Oliver, hn Oliver, n Stewart)

Now that John Oliver has completed his summer stand-in for Jon Stewart, it is time for a replacement. The old sequence hn Oliver will be replaced with the new sequence n Stewart, resulting in The Daily Show with Jon Stewart.

replace(Sample String, s, Replaced)

In this example, the original string does not contain the old value s anywhere, so no replacement occurs and the original string is returned.

replace(Led Zeppelin.[remastered], .[remastered])

Removes the trailing old value .[remastered] from the original string, resulting in Led Zeppelin. Because no new string is specified, the default empty value is used as a replacement, effectively stripping the old value.

Right(…): Retrieves a specified number of characters from the right of a string

Examples right([filename], 3)

Returns the last three characters from the filename (typically this is the file's suffix).

List Manipulation

Media Center supports several different types of fields, one of them being the List type. A List type is a library field of type List, or an expression coerced into a list type.

The functions in this section provide the ability to manipulate lists and list items. A list is a sequence of strings, each separated from one another by an arbitrary delimiter. The default delimiter is a semicolon. Media Center does not make a strict distinction between a string and a list of strings. In fact, a list is just a string, and it is safe to think of a string as a list with zero or more arbitrary delimiter sequences. For example, the string "2013-08-17" can be thought of as a dash-delimited list with the three items "2013", "08" and "17".

This weak typing is very useful since a list, for example, "John; Sally" that contains the two items "John" and "Sally" can be manipulated not only using the list functions in this section, but because it is just a string, it can also be manipulated with string functions. For example, taking the same list above and combining it with the string "; Joe" adds a new item to the list "John; Sally; Joe", and removing the first 6 characters with RemoveLeft() would produce a now shortened string/list "Sally; Joe". The list manipulation functions make this job easier, especially when using the default semicolon delimiter. Furthermore, since any character or sequence of characters can be considered as a list delimiter, any string can be treated as a list, and the functions in this section can be used on any string as needed.

In some areas such as a panes column, or a category view, Media Center gives special treatment to List types. For example, using semicolon as the delimiter, a List will be automatically split apart into its individual items.

ListBuild(…): Constructs a list from a series of items

Description listbuild(mode, delimiter, item1, item2, )

The ListBuild() function constructs a list from item1, item2, ... using a supplied delimiter to separate the individual items in the resulting list. The construction mode affects how empty items are handled - they can be included or excluded. The mode typically used exclude empty items, so that lists do not contain empty slots. However, there are occasions when retaining empty slots is useful, such as when using a list to act like an array where data is stored in particular slots so that the ListItem() function may later retrieve values at a given index. It can also be useful when calculating several expressions and combining the results into a single list for presentation; by including all items, items can be made to line-up for visual inspection in a column.

Available mode values:

0Include empty values
1Exclude empty values

The delimiter argument specifies the character or character sequence to be inserted in between items in the list. An unspecified delimiter will result in a delimiter-less concatenation of the supplied arguments item1, item2, etc.

Argument delimiter is optional (defaults to EMPTY).

Examples listbuild(1, ;, Bennie, June)

Returns a standard semicolon-separated list containing two items Bennie; June.

listbuild(1, \, [album artist (auto)], [album])

Builds a backslash-separated list combining the two fields album artist (auto) and album. This is useful for building panes column or categories hierarchies in a view.

ListClean(…): Various list operations

Description listclean(list, mode, delimiter)

The ListClean() function performs one of the operations specified by mode on the given list. The specified delimiter separates list items.

1Remove duplicates
2Reverse the order of items

Argument delimiter is optional (defaults to SEMICOLON).

Examples listclean(c;b;c;a, 1)

Removes duplicates from the list, returning c;b;a.

listclean(d;c;b;a, 2)

Reverses the list items, returning a;b;c;d.

listclean(\a\x\x\x\z, 1, \)

Removes duplicates from a backslash-separated list, returning \a\x\z.

ListCombine(…): Combines two delimited lists into a single delimited list

Description listcombine(list1, list2, input delimiter, output delimiter, mode)

The ListCombine() function returns a single list after performing the operation specified by mode on the two lists list1 and list2. An input delimiter and an output delimiter may be specified. The input delimiter is effective for both list1 and list2, and the output delimiter will be used in the returned list, replacing the input delimiter from both list1 and list2.

Available mode values:

0Combine lists removing duplicates (order is preserved).
1Output only items contained in both lists (order is preserved).

Argument input delimiter is optional (defaults to SEMICOLON).

Argument output delimiter is optional (defaults to SEMICOLON).

Argument mode is optional (defaults to 0).

Examples listcombine(a;b;e, a;b;c;d)

Returns a;b;e;c;d. This example uses the default mode 0 to combine list1 with list2, preserving the order of items. The default ; input delimiter and output delimiter is used.

listcombine(a;b;e, a;b;c;d, ;, ;, 1)

Returns a;b. The input delimiter and output delimiter are both specified as ;, and mode 1 is used to produce a list of only items that exist in both list1 and list2.

listcombine(a-c, c-f, -, ..., 0)

Returns a...c...f. The input delimiter is -, while the output delimiter is ..., and mode 0 combines both lists.

listcombine(a#@#c, c#@#f, #@#, ., 0)

Returns a.c.f. This example demonstrates how to combine two lists with duplicates removed while replacing a multi-character input delimiter #@# with a single-character output delimiter ..

listcombine([people], [places])&datatype=[list]

The result here would be a single, semicolon delimited list containing all the list items from the [people] and [places] fields. For example, if [people] contains Family\Mum; Family\Dad; Family\Gran, and [places] contains UK\Scotland\Edinburgh; UK\Scotland\Edinburgh\Edinburgh Castle, the output list would be Family\Mum; Family\Dad; Family\Gran; UK\Scotland\Edinburgh; UK\Scotland\Edinburgh\Edinburgh Castle. Using the &datatype=[list] cast makes the expression split individual list items in a panes or categories view.

ListCount(…): Returns the number of items in a list

Description listcount(list, delimiter)

The ListCount() function returns the number of items that exist in a list delimited by delimiter.

Argument delimiter is optional (defaults to SEMICOLON).

Examples listcount([keywords])

Returns the number of keywords for the file.

listcount([filename (path)], \)

Returns the number of the directories in a Windows drive-based file path. The example demonstrates that non-List type fields can be used with the functions in this section. While the delimiter specified here is \, an escaped forward slash // could be used when applicable.

ListItem(…): Returns an item from a location in a list

Description listitem(list, position, delimiter)

The ListItem() function returns the item from the specified position in the list. Items in a list are zero-based, so the first item in the list is located at position 0. Nothing is returned with the position is outside the bounds of the list.

Argument delimiter is optional (defaults to SEMICOLON).

Examples listitem(a;b;c, 1)

Returns b, since position 1 is the second item in the list a;b;c.

listitem(1:04:47, 2, :)

Using the delimiter :, returns item at position 2, which is the seconds value 47 from the time 1:04:47.

ListSort(…): Sort a list of values

Description listsort(list, mode, delimiter)

The ListSort() function sorts a list in the order according to mode, using the specified delimiter.

Available mode values:

0Ascending sort
1Descending sort

Argument mode is optional (defaults to 0).

Argument delimiter is optional (defaults to SEMICOLON).

Examples listsort(c;a;b)

Returns a;b;c, using the default ascending mode and (:) delimiter.

listsort(Joe Baxter/, Sally Henson/, Sue Smith, 1, /,)

Returns Sue Smith,Sally Henson,Joe Baxter. Note the requirement to escape the , characters within the list string and in the specified delimiter itself.

listsort([artist];[composer])

Sorts the combined artist and composer lists in ascending order. Note the simple manual construction of a single List by combining the two List type fields, and forcing a ; between the two.

Date and Time Functions

Media Center provides several functions for the conversion, formatting and generation of dates and times. Date and time for a Date-type field is stored internally as a single floating-point number, where the integer portion represents the number of days since the Epoch, and the decimal portion represents the fraction of a day in seconds. The Epoch is defined as December 30th, 1899 at 00:00:01. Certain fractional values and whole numbers are used to encode Time-only and Year-only values. For example, the internal Date value of "2" is considered as 1900, without a time when converted using the DateTime conversion format of FormatDate(), whereas adding a small fraction and using "2.001" instead produces a value of "1/1/1900 12:01 am". These details are only relevant if you are doing conversions.

The Windows locale setting will affect the interpretation and formatting of date and time information.

ConvertDate(…): Converts a human-readable date to the internal format required for use in date fields

Description convertdate(date_time string)

Converts a human-readable date_time string into the internal floating-point representation used by Media Center to store a date and time.

Examples convertdate(3//6//2012)

Returns the value 40974, which is the internal floating-point representation of the date string 3/6/2012. This value can used by any field of type Date, or in any function that requires as input a Date type value.

formatdate(convertdate(12//2//1985), decade))

Converts the date string 12/2/1985 (note: December 2nd, not February 12th) into a Date type value, and then formats the result as a decades grouping, returning 1980's. This might be used for creating decade groupings.

FormatDate(…): Formats a date value in a specified manner

Description formatdate(date value, format specifier, empty label)

The FormatDate() function provides custom formatting of date and time values through the use of a format specifier. Output will be formatted according to format specifier.

The date value is a Media Center internal floating-point date/time representation, stored in Date fields, and output from various functions such as Now() and ConvertDate(). To pass a field of type Date to FormatDate(), use the raw (unformatted) field specification, such as "[Date Imported,0]".

The format specifier provides a recipe for converting the internal value into a human-readable string. Supported are a variety of Windows style, strftime() style, and Media Center-specific formats specifiers. Construct the format specifier from any number or combination of those defined in the following table. Additionally, any non-format characters will be output without interpretation. This allows creating rich date/time output strings. To output a word that is a reserved format specifier, surround the word with double-quotes.

The empty label argument will be output if the date value is empty.

Argument date value is optional (defaults to [date,0]).

Argument empty label is optional (defaults to EMPTY).

Examples formatdate(year-month)

Outputs the file's date formatted as Year-Month, such as 2012-April. The default date value of [Date,0] is used.

formatdate([last played,0], yyyy//MM//dd, Not Yet)

Returns the file's last played date as year/month/day without the time, ignoring the system locale setting. If a file has no last played value, the expression will output Not Yet instead.

formatdate([date modified,0], month %Y)

Returns the file's modification date/time in the form of a long month name and a four-digit year, such as December 2010.

formatdate([date imported,0], The "year" is year)

Outputs the The year is ####, where #### is the year the file was imported into the Library. Note that the word year must be surrounded in double-quotes to have it considered as literal text, and not the Year format specifier.

formatdate([date imported,0], month)&datatype=[month]

This examples is the same as the previous example, but includes a cast to the Month type &datatype=[month]. This cast can be used to cause chronological month-sorting, rather than month name alphabetic-sorting, in a panes or category view. Data-type coercion is discussed above.

Additional Examples

Date formatting development discussion, usage tips and examples.

Now(…): Retrieve and display the system date

Description now()

The Now() function returns a floating-point value representing the current system date and time. It is generally useful for performing date arithmatic in expressions that desire to figure out elapsed time. Any raw date field or value representing a date can be subtracted from Now() to realize an elapsed time delta.

Examples now()

When run on Aug 17, 2013 at 19:28:00, returns approximately 41503.811115995.

formatdate(now(), date)

Returns the current date, without a time component, formatted according to the system's locale settings.

formatdate(math(now() - 3, dddd dd MMMM yyyy H:mm)

The date from three days ago is formatted as something like Wednesday 14 August 2013 19:35. This is accomplished by subtracting the value 3, which would be days, from Now(), and its output formatted by FormatDate().

File Path and Identifier Functions

The functions in this section provide specific file-related information such as a file's name, path, volume, and other Media Center internal information.

FileDBLocation(…): Identifies a file's databases

Description filedblocation(format)

The FileDBLocation() function returns identifiers in the specified format specified that indicate to which internal database(s) a file belongs. Media Center maintains several internal databases to track a file's disposition. This function is primarily for technical use only, and will have little utility for most users.

Available format values:

0Semicolon-separated list of formatted database names
1Numeric value of OR'd database bit flags

The table below provides common values output from FileDBLocation():

Database nameBit position
Main0
Playing Now1
CD2
Explorer3
Other (16)5
Other (6)6
Grouping7
Removed8
Podcast10
Other (4096)12
Stacks14
Category Images18
Bad19

Argument format is optional (defaults to 0).

Examples filedblocation()

For a file in the Main and Other (4096) databases, the result would be Main; Other (4096).

filedblocation(1)

The result from the same file would be 4096 (bit 0 and bit 12 set).

Additional Examples

Sample expression that uses FileDBLocation() to show a file's databases.

FileFolder(…): Returns the name of a file's parent

Description filefolder(filepath, level)

The FileFolder() function returns parent sub-folder name for filepath. The level argument specifies which parent sub-folder name to return, working the filepath from right-to-left (i.e. bottom of the folder tree upwards to the top). A value of 0 specifies a file's immediate parent, 1 its grandparent, etc., up to the root of the filepath. A value of Unassigned will be returned when the specified level exceeds the root of the filepath.

Argument filepath is optional (defaults to [filename]).

Argument level is optional (defaults to 0).

Examples filefolder()

Returns the name of the file's parent folder.

filefolder([filename,0], 0)

Same as the previous example.

filefolder(c:\some\folder\for\a\file.ape, 2)

Returns the great grandparent sub-folder named folder.

filefolder(c:\some\other\folder\a\, 2)

Returns the folder named other. Notice the file name is not required in the filepath. FileFolder() works by looking from the end of the filepath until it finds a backslash \.

FileKey()(…): Returns a file's unique internal identifier

Description filekey()()

The FileKey()() function returns the unique identifier associated with a file. Media Center assigns a unique identifier to each file in the Library. It is useful in expressions when referring to individual files is necessary. Services such as MCWS use this value to reference a file.

Examples filekey()

Returns a integer value, such as 22029495, unique for each file in the Library.

FileName(…): Returns a file's name component

Description filename(filepath, include suffix)

This function returns the file name part of filepath. Inclusion of the file's suffix depends on the include suffix argument.

0Suppress file suffix
1Include file suffix

Argument filepath is optional (defaults to [filename]).

Argument include suffix is optional (defaults to 1).

Examples filename(C:\Music\File.mp3)

The output is File.mp3.

filename(C:\Music\File 2.wav, 0)

The output does not include the file suffix, and is File 2.

filename()

Returns the value contained in the field [filename (name)].

FilePath(…): Returns a file's path component

Description filepath(filepath)

This function will return the path portion of the specified file path.

The filepath should be a rooted path. For Windows, this includes the drive letter or leading \\ for UNC paths. For *nix-based systems, this includes the root /. The field [filename (path)] is equivalent to FilePath(), and is generally preferred.

Argument filepath is optional (defaults to [filename]).

Examples filepath(C:\Music\File.mp3)

Returns C:\Music.

filepath()

Returns the value contained in the field [filename (path)].

FileVolume(…): Returns a file's volume name component

Description filevolume(filepath)

The FileVolume() function returns the volume name component of the specified file path. The path should be a rooted path (see the same comment above for FilePath(). For *nix-based systems, the output is empty. The field [volume name] is equivalent to FileVolume(), and is generally preferred.

Argument filepath is optional (defaults to [filename]).

Examples filevolume(C:\Music\File.mp3)

Outputs C:.

filevolume()

Returns the value contained in the field [volume name].

Miscellaneous Functions

The functions in this section are varied and have specialized applicability. Some are primarily used internally by MC to generate values available in various Library fields.

AlbumArtist(…): Returns a file's calculated album artist

Description albumartist()

This function calculates the album artist value used in various views and fields. It is used to populate the Library field album artist (auto) with its value. Either the field or AlbumArtist() can be used.

Examples albumartist()

Returns the value present in the album artist (auto) field.

Additional Examples

Describes the algorithm used by AlbumArtist() to calculate the "album artist (auto)" field's value.

AlbumKey(…): Returns a unique album key for a file

Description albumkey()

The AlbumKey() function returns "[album artist (auto)] - [album]". It is a convenience function, used to return the generally unique album / artist combination string used to distinguish between two like-named albums such as "Greatest Hits".

Examples albumkey()

For an album named Greatest Hits and an album artist (auto) of The Eagles, returns The Eagles - Greatest Hits.

AlbumType(…): Returns the album type for a file

Description albumtype()

The AlbumType() function returns a description regarding an album's completeness and its quantity of artists. It is used to populate the Library field album type with its value. Either the field or AlbumType() can be used.

Examples albumtype()

Returns, for example, Single artist (complete), or Multiple artists (incomplete).

Counter(…): Counts upwards in specified increments

Description counter(start value, increment)

The Counter() function outputs a monotonically increasing number (more simply stated, it counts) from a start value, and each time called, increases by the increment value. It is useful for sequentially numbering fields. The Counter() function maintains an internal counter, and it resets itself to zero after five seconds of inactivity.

Because Counter() continues to count, it should only be used in single-use situations such as assigning its output to some field through field value assignment, for example, =counter(). With proper care, it can be used as part of an expression in the Rename, Move & Copy tool, but see also CustomData().

It is not recommended for use in any context that continually refreshes its content, such as in a panes column, file list, or expression-based custom query. Probably the best way to understand the results is to test the first example below as an expression column in a file list, and move the mouse around over that column.

Argument start value is optional (defaults to 1).

Argument increment is optional (defaults to 1).

Examples counter()

Outputs values starting at 1, and incrementing by one, it will return 1, 2, 3, ... until no longer called. This might be used, for example, to assign to the [Track #] field of several tracks using the field assignment expression =counter().

padnumber(counter(370, 2), 4)

Outputs numbers beginning from 370, incremented by two each, and padded to four digits. For example, 0370, 0372, 0374, etc.

CustomData(…): Returns internal data to the expression language

Description customdata(mode)

The CustomData() function supports returning Media Center internal data to the expression language. Currently there is only one supported use, which is to use CustomData() in the Rename, Move & Copy tool to assist in numbering files.

Available mode values:

#Returns a file's row number in the Rename, Move & Copy tool
Examples Spring_Break_Bash_padnumber(customdata(#), 4)

In the Rename, Move & Copy tool, each consecutive file would be named Spring_Break_Bash_ followed by a four digit, zero-padded number starting at 0001.

Math(…): Evaluates a given mathematical formula

Description math(expression)

The Math() function performs mathematical calculations. Standard arithmetic operators are supported, as are various numerical, trigonometric, and comparative functions. Simple variables are supported, as are multiple statements.

Arithmetic Operators + Addition
- Subtraction
* Multiplication
/ Division
^ Power
 % Modulo
Boolean Operators  ! NOT
& AND

Grouping Operators ( ) Precedence grouping
Comparison Operators } Absolute value maximum (i.e. x or y that is maximum distance from 0).
{ Absolute value minimum (i.e. x or y that is minimum distance from 0).
> Distance between x and y, positive when x greater than y, negative otherwise.
< Distance between x and y, positive when x less than y, negative otherwise.
Functions abs(x) Returns the absolute value of x.
sign(x) Returns the sign of x (1 when x >= 0, -1 when x < 0).
log(x) Returns the natural logarithm (base e) of x.
log10(x) Returns the common logarithm (base 10) of x.
pow(x,y) Returns x raised to the y-th power.
rand(x) Returns a random value ranging between 0 to x.
randn(x) Returns a random value ranging between -x and x.
Comparison Functions min(x,y) Returns the minimum value of x and y.
max(x,y) Returns the maximum value of x and y.
equal(x,y) Returns 1 when x = y, 0 otherwise.
below(x,y) Returns 1 when x < y, 0 otherwise.
above(x,y) Returns 1 when x > y, 0 otherwise.
Formatting Functions int(x) Returns the integer portion of x.
frac(x) Returns the fractional portion of x.
round(x) Returns x rounded to the nearest whole number.
trunc(x,n) Returns x truncated to n decimal places.
Trigonometric Functions atan(x) Returns the arctangent of x.
cos(x) Returns the cosine of x.
sin(x) Returns the sine of x.
tan(x) Returns the tangent of x.
abscos(x) Returns the absolute value of cosine(x).
abssin(x) Returns the absolute value of sin(x).

The order of operator precedence is summarized as follows, from top to bottom:

(   ) 
  ! 
  ^ 
*   /Left to right
+   -Left to right
|   &Left to right

Variables may be assigned and used by specifying a simple string of letters. Examples: math(val=2) or math(x=pow(2,3)).

Multiple equations may be specified, each separated by a semicolon. Expressions are evaluated left to right. The final value of the Math() function will be the result of the right-most equation. For example, the equation math(x=4; pow(2^x)) will output 16.

Note: Empty fields

Fields used inside of Math() are expanded (interpolated) directly. Fields with empty values may produce incomplete Math() statements. For example, if the field [number plays] is empty, an expression such as math([number plays] + 2) would be seen by Math() as + 2. This incomplete expression would produce a syntax error. See the Additional Examples for more information.

Note: Locales and Commas

Special care must be taken with the Math() function and locales that use , (comma) as a decimal separator. Many Media Center fields and the return values from functions may contain comma as the decimal point. Your expressions will need to Replace() these before passing the values to Math(), which always uses dot . as the numeric decimal point.

For example, the expression math(1,5 + 1,5) will fail since Math() does not consider 1,5 to be a valid number.

Fields that cause problems are any fields that produce floating-point values, such as any Date type field in raw format (e.g. [date,0], [last played,0], [date modified,0], and [date imported,0]), or any textual field that contains floating-point values that will be used for various calculations (e.g. any of the Dynamic Range variants). Certain functions such as Now() and ConvertTime() also return localized floating-point values.

Handling this problem is not difficult. Before passing any floating point number to Math(), use Replace() first. See the examples below.

Examples math(10 + 4)

Returns 14.

math(10 + 2 * 25)

Returns 60, demonstrating that multiplication has higher precedence than addition.

math((10 + 2) * 25)

Returns 300, demonstrating that parenthesis grouping has higher precedence than multiplication.

math(replace(now(), /,, .) - replace([last played,0], /,, .))

The , is replaced by a . in the output of both Now() and in the raw field value [last played,0]. Note that the comma must be escaped so that it is seen as an argument and not as an argument separator.

math(replace(now() - [last layed,0], /,, .))

The same as the previous example, but is more efficient and simpler since it calls Replace() just once on the entire string to be passed to Math().

Additional Examples

An explanation and some solutions for fields that evaluate to empty within Math().

Size(…): Returns a file's size in a format specific to the media type

Description size()

The Size() function returns media size information specific to the particular media type. It is used to populate the Library fields duration and dimensions with their values. Either the field or Size() can be used.

Type of information reported by size for the file's media type:

AudioDuration
VideoDuration
ImageDimensions
DataNo information returned.
Examples size()

Returns values such as 400x225 for images, or 3:09 for audio files.

TrackNumber(…): Returns a file's track # value

Description tracknumber()

The TrackNumber() function returns a file's track #, or 0 if the no value exists. It is used to populate the Library field track # with its value. Either the field or TrackNumber() can be used.

Examples tracknumber()

Returns the value present in the track # field.

TVInfo(…): Miscellaneous television and other pre-formatted information

Description tvinfo(type)

The TVInfo() function is multi-purpose, and returns a specific type of information about television recordings, programs, and pre-formatted informational strings for use in captions, thumbnails, grouping, etc.
