Controls

Item

Description

Name

In this field, view or edit the variable name in the format $<variable_name>$.

Expression

In this field, specify the expression to have the value of the corresponding template input field calculated automatically.

This expression may contain constructs of the following basic types:

  • String constants in double quotes.

  • The name of another variable defined in a live template.

  • Predefined functions with possible arguments.

Type an expression manually or select a predefined function from the list. The list shows also the number and type of parameters, if any, for the selected function. The available functions are listed alphabetically in the Functions table.

Default value

In this field, specify the default string to be entered in the corresponding input field of the expanded template, if the expression does not give any result after calculation.

Note that a default value of a variable is an expression that can refer to other live template variables. To define the default value as a literal, enclose it in quotation marks.

Skip if defined

Select this checkbox to have JetBrains Rider proceed with the next input field, if the value of the current input field is defined.

Move Up / Move Down

Use these buttons to change the order of variables in the list. The order of variables in the table determines the order in which JetBrains Rider will switch between the corresponding input fields when the template is expanded.

Predefined Functions to Use 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

To use a different format, provide a parameter according to the SimpleDateFormat specification. For example, the function date("Y-MM-d, E, H:m") will return the date formatted as 2019 - 07 - 5, Fri, 12:56.

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, and so on.

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)

Find all occurrences of Pattern in a String and replace it with Replacement. You can specify the pattern as a regular expression to find everything that matches it in the string.

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 filename. 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.

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

To use a different format, provide a parameter according to the SimpleDateFormat specification. For example, the function time("H:m z") will return the timestamp formatted as 13:10 UTC.

underscoresToCamelCase(String)

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

underscoresToSpaces(sParameterWithUnderscores)

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

user()

Returns the name of the current user.
