The dialog opens when you click Edit Variables in the Template Text area on the Editor | Live Templates page of GoLand settings (Ctrl+Alt+S).

Use this dialog box to create and edit expressions for variables in the selected live template.

Controls

Item

Description

Name

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

Expression

In this text box, 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 drop-down 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 text box, 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 GoLand 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 GoLand will switch between the corresponding input fields when the template is expanded.

Predefined Functions to Use in Live Template Variables

Item

Description

blockCommentEnd

Returns the characters that indicate the end of a block comment in the current language context.

blockCommentStart

Returns the characters that indicate the start of a block comment in the current language context.

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.

classNameComplete()

This expression substitutes for the type name completion at the variable position.

clipboard()

Returns the contents of the system clipboard.

commentEnd()

Returns the characters that indicate the end of a comment in the current language context. The return value is empty if line comments are defined in the current language.

commentStart()

Returns the characters that indicate the start of a comment in the current language context. If line comments are defined in the current language, their start indicator is preferable.

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.

errorVariable()

Returns the first error variable in the current context. Autocompletes all error variables in the current context.

errorVariableDefinition(expressionWithErrorResult)

Converts an expression to the variable definition if the expression returns the error type. For example, if the a() function returns (int, error), the errorVariableDefinition("a()") expression returns _, err.

escapeString(sEscapeString)

Escapes the string specified as the parameter.

fieldName()

Returns the first field name in the current context. Autocompletes all field names in the current context.

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.

groovyScript("groovy code", arg1)

Returns a Groovy script with the specified code.

You can use the groovyScript() function with multiple arguments. The first argument is the text of the script that is executed or the path to the file that contains the script. The next arguments are bound to the _1, _2, _3, ..._n variables that are available inside your script. Also, the _editor variable is available inside the script. This variable is bound to the current editor.

JsArrayVariable()

Returns the name of the current JavaScript array.

jsClassName()

Returns the name of the current JavaScript class.

jsComponentTypeOf()

Returns the type of the current JavaScript component.

jsDefineParameter

Based on the name of the module, returns the parameter from define(["module"], function (<parameter_in_question>>) {}).

jsMethodName()

Returns the name of the current JavaScript method.

jsQualifiedClassName()

Returns the complete name of the current JavaScript class.

jsSuggestIndexName()

Returns a suggested name for an index variable from most commonly used ones: i, j, k, etc. The names that are not used in the current scope yet are shown first.

jsSuggestVariableName()

Returns the suggested name for a variable based on its variable type and initializer expression, according to your code style settings that refer to the variable naming rules.
For example, if it is a variable that holds an element within an iteration, GoLand makes a guess on the most reasonable name, taking into account the name of the container that is iterated.

jsSuggestDefaultVariableKind(Boolean)

The Boolean parameter determines whether constants are allowed or not in the current context. If no parameter is specified, constants are allowed. When the templates expands, a drop-down list is shown with var, let, const options for TypeScript and ES6 and with only one var option for earlier JavaScript versions.

jsSuggestImportedEntityName()

Suggests the name for import statements of the type `import * as $ITEM$ from "$MODULE$"` or `import $ITEM$ from "$MODULE$"` based on the file name.

lineCommentStart

Returns the characters that indicate the start of a line comment in the current language context.

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)

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

nonBlankVariable

Receives a list of expressions as input and returns the first expression that is not empty (_). For example, _,_,a,b returns a.

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.

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.

underscoresToSpaces(sParameterWithUnderscores)

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