File | Settings | IDE Settings | Live Templates - Edit Variables

settings

The dialog box opens when you click the Edit Variables button in the Template Text area on the Live Templates page of the Settings dialog box.

Note

The Edit Variables button is enabled only if the template body contains at least one user-defined variable, that is, a variable different from $END$ or $SELECTION$.

Use this dialog box to create and edit expressions within 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:

  • Predefined functions with possible arguments.
  • String constants in double quotes.
  • The name of another variable defined in a live template.

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 check box to have WebStorm 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 WebStorm will switch between the corresponding input fields when the template is expanded.

Functions

Item Description
capitalize(<name>) Capitalizes the first letter of the name passed as a parameter.
capitalizeAndUnderscore(<String>) Capitalizes the all letters of a CamelCase name passed as a parameter, and inserts an underscore between the parts. For example, if the string passed as a parameter is FooBar, then the function returns FOO_BAR.
clipboard() Returns the contents of the system clipboard.
complete() This expression substitutes for the code completion invocation at the variable position.
completeSmart() This expression substitutes for the smart type completion invocation at the variable position.
date() Returns the current system date in the specified format.

By default, the current date is returned in the default system format. However, if you specify date format in double quotes, the date will be presented in this format:

date_format

decapitalize(<name>) Replaces the first letter of the name passed as a parameter with the corresponding lowercase letter.
escapeString() Escapes the specified string.
