Predefined functions to be used in live template variables

Item

Description

camelCase(String)

Converts a string into camelCase. For example, camelCase(my-text-file), camelCase(my text file), and camelCase(my_text_file) all return myTextFile.

capitalize(String)

Capitalizes the first letter of the parameter.

capitalizeAndUnderscore(sCamelCaseName)

Capitalizes all the letters of a CamelCase name passed as the parameter, and inserts an underscore between the parts. For example, capitalizeAndUnderscore(FooBar) returns FOO_BAR.

complete()

Invokes code completion at the position of the variable.

completeSmart()

Invokes smart type completion at the position of the variable.

concat(expressions...)

Returns a concatenation of all the strings passed to the function as parameters.

date(sDate)

Returns the current system date in the specified format.

Without a parameter, the current date is returned in the default system format.

date_format
decapitalize(sName)

Replaces the first letter of the parameter with the corresponding lowercase letter.

defaultReturnValues

Returns the default value if the expression is used in the return statement. Uses the errorVariableName parameter if the expression is of the error type.

enum(sCompletionString1,sCompletionString2,...)

Returns a list of comma-separated strings suggested for completion when the template is expanded.

escapeString(sEscapeString)

Escapes the string specified as the parameter.

expectedType()

Returns the expected type of the expression into which the template expands. Makes sense if the template expands in the right part of an assignment, after return, etc.

fileName()

Returns the name of the current file with its extension.

fileNameWithoutExtension()

Returns the name of the current file without its extension.

firstWord(sFirstWord)

Returns the first word of the string passed as the parameter.

lineNumber()

Returns the current line number.

lowercaseAndDash(String)

Converts a camelCase string into lower case and inserts n-dashes as separators. For example, lowercaseAndDash(MyExampleName) returns my-example-name.

regularExpression(String, Pattern, Replacement)

Makes a replacement in a string according to a specified pattern.

snakeCase(String)

Converts a string into snake_case. For example, snakeCase(fooBar) returns foo_bar.

spaceSeparated(String)

Converts a string into lowercase and inserts spaces as separators. For example, spaceSeparated(fooBar) returns foo bar.

spacesToUnderscores(sParameterWithSpaces)

Replaces spaces with underscores in the string passed as the parameter. For example, spacesToUnderscores(foo bar) returns foo_bar.

substringBefore(String,Delimiter)

Removes the extension after the specified delimiter and returns only the file name. This is helpful for test file names (for example, substringBefore($FileName$,".") returns component-test in component-test.js).

time(sSystemTime)

Returns the current system time in the specified format.

underscoresToCamelCase(String)

Replaces underscores with camelCase letters in the string passed as the parameter. For example, underscoresToCamelCase(foo_bar) returns fooBar.
