Edit Template Variables Dialog

File | Settings | Live Templates - Edit Variables

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

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 for variables in the selected live template.

On this page:


NameIn this text box, view or edit the variable name in the format $<variable_name>$.
ExpressionIn 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 valueIn 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 definedSelect this check box to have CLion proceed with the next input field, if the value of the current input field is defined.
Move Up / Move DownUse these buttons to change the order of variables in the list. The order of variables in the table determines the order in which CLion will switch between the corresponding input fields when the template is expanded.

Predefined Functions to Use in Live Template Variables

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.
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:

decapitalize(<name>) Replaces the first letter of the name passed as a parameter with the corresponding lowercase letter.
enum(...)List of comma-delimited strings suggested for completion at the template invocation.
escapeString() Escapes the specified string.
expectedType() Returns the type which is expected as a result of the whole template. Makes sense if the template is expanded in the right part of an assignment, after return, etc.
fileName()Returns file name with extension.
fileNameWithoutExtension()Returns file name without extension.
firstWord(String) Returns the first word of the string passed as a parameter.
lineNumber() Returns the current line number.
snakeCase(String) Returns snake_case string out of CamelCase string.
time() Returns the current system time.
underscoresToCamelCase Returns the string passed as a parameter with CamelHump letters substituting for underscores. For example, if the string passed as a parameter is foo_bar, then the function returns fooBar.
underscoresToSpaces(VAR) Returns the string passed as a parameter with spaces substituting for underscores.
user() Returns the name of the current user.
