File | Settings | IDE Settings | Live Templates - Edit Variables
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.
In this topic:
|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
This expression may contain constructs of the following basic types:
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 IntelliJ IDEA 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 IntelliJ IDEA will switch between the corresponding input fields when the template is expanded.|
|annotated("annotation qname")||Creates a symbol of type with an annotation that resides at the specified location.|
|arrayVariable()||Suggests all array variables applicable in the current scope. For an example, see Live Templates in the iterations group.|
|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.|
|castToLeftSideType()||Casts the right-side expression to the left-side expression type. It is used in the iterations group to have a single template for generating both raw-type and Generics Collections.|
|className()||Returns the name of the current class (the class where the template is expanded).|
|classNameComplete()||This expression substitutes for the class name completion at the variable position.|
|13.0+ 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.|
|componentTypeOf (<array variable or array type>)||Returns component type of an array. For example, see the Live Templates in the iterations group in the other group.|
|currentPackage()||Returns the current package name.|
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.|
|descendantClassEnum(<String>)||Shows the children of the class entered as a string parameter.|
|enum(...)||List of comma-delimited strings suggested for completion at the template invocation.|
|13.0+ 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.|
|groovyScript("groovy code")||Returns Groovy script with the specified code.
12.0+ You can use groovyScript macro with multiple arguments. The first argument is a script text that is executed or a path to the file that contains a script. The next arguments are bound to _1, _2, _3, ..._n variables that are available inside your script.
Also, _editor variable is available inside the script. This variable is bound to the current editor.
|guessElementType (<container>)||Makes a guess on the type of elements stored in a java.util.Collection. To make a guess, IntelliJ IDEA tries to find the places where the elements were added to or extracted from the container.|
|iterableComponentType(<ArrayOrIterable>)||Returns the type of an iterable component, such as an array or a collection.|
|iterableVariable()||Returns the name of a variable that can be iterated.|
|lineNumber()||Returns the current line number.|
|methodName()||Returns the name of the embracing method (where the template is expanded).|
|methodParameters()||Returns the list of parameters of the embracing method (where the template is expanded).|
|methodReturnType()||Returns the type of the value returned by the current method (the method within which the template is expanded).|
|qualifiedClassName()||Returns the fully qualified name of the current class (the class where the template is expanded).
Clear the Shorten FQ names check box.
|rightSideType()||Declares the left-side variable with a type of the right-side expression. It is used in the iterations group to have a single template for generating both raw-type and Generics Collections.|
|snakeCase(String)||Returns snake_case string out of CamelCase string.|
|subtypes(TYPE)||Returns the subtypes of the type passed as a parameter.|
|suggestIndexName()||Suggests the name of an index variable. Returns i if there is no such variable in scope, otherwise returns j if there is no such variable in scope, etc.|
|suggestVariableName()||Suggests the name for a variable based on the variable type and its 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 iteration, IntelliJ IDEA makes a guess on the most reasonable names, also taking into account the name of the container being iterated.
|suggestFirstVariableName()||Doesn't suggest true, false, this, super.|
|time()||Returns the current system time.|
|typeOfVariable(VAR)||Returns the type of the variable passed as a parameter.|
|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.|
|variableOfType(<type>)||Suggests all variables that may be assigned to the type passed as a parameter, for example variableOfType("java.util.Vector"). If you pass an empty string ("") as a parameter, suggests all variables regardless of their types.|
