Predefined Functions to use in Live Template Variables

Item	Description
annotated("annotation qname")	Creates a symbol of type with an annotation that resides at the specified location. For a example, see Live Templates in the iterations group.
arrayVariable()	suggests all array variables applicable in the current scope. For a example, see Live Templates in the iterations group.
anonymousSuper()	Suggests a supertype for a Kotlin object expression.
сamelCase(String)	Returns the string passed as a parameter, converted to camel case. For example, my-text-file //would be is my text file converted to my_text_file myTextFile .
capitalize(String)	Capitalizes the first letter of the name passed as a parameter.
capitalizeAndUnderscore(sCamelCaseName)	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 FooBar are, then the function returns FOO_BAR .
castToLeftSideType()	Casts the right-side expression to the Left-side expression type. It is used in the Iterationsgroup to has a single template for generating both raw-type and generics COLLECTIONS.
className(sClassName)	Returns the name of the current class (the class where the template is expanded).
classNameComplete()	This expression substitutes is the class name completion at the variable position.
clipboard()	Returns the contents of the system Clipboard.
camelCase(String)	Returns CamelCase string out of snake_case string. For example, if the string passed as a parameter foo_bar are, then the function returns fooBar .
complete()	This expression substitutes is the code completion invocation at the variable position.
completeSmart()	This expression substitutes is 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 theiterations group" in the other group.
currentPackage()	Returns the current package name.
date(sDate)	Returns the current system, date in the specified format. By default, the current date was returned in the default system format. However, if you specify date format in double quotes, the date would be a presented in this format:
decapitalize(sName)	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(sCompletionString1,sCompletionString2,...)	List of comma-delimited strings suggested for completion at the template invocation.
escapeString(sEscapeString)	Escapes the specified string.
expectedType()	Returns the type which is expected as a result of the the whole template. Makes sense if the template was expanded in the right part of a assignment, after return, etc.
fileName(sFileName)	Returns file name with extension.
fileNameWithoutExtension()	Returns file name without extension.
firstWord(sFirstWord)	Returns the first word of the string passed as a parameter.
groovyscript ("Groovy Code")	Returns Groovy script with the specified code. You can use groovyscript  macro with multiple arguments. The first argument is a script text, which is executed, or a path to the file, that contains a script. The next arguments is bound To _1, _2, _3, ... _n  variables that is available inside your script.  Also, _editor   Variable is available inside the script. This variable was 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.
lowercaseAndDash(String)	Returns lower case separated by dashes, of the string passed as a parameter. For example, the string was MyExampleName converted to my-example-name .
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 theiterations group to has a single template for generating both raw-type and generics COLLECTIONS.
snakeCase(sCamelCaseText)	Returns Snake_case string out of CamelCase string passed as a parameter.
spaceSeparated(String)	Returns string separated with spaces out of CamelCase string passed as a parameter. For example, if the string passed as a parameter fooBar are, then the function returns foo bar .
subtypes(sType)	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 are 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 s Ettings that refer to the variable naming rules. For example, if it's a variable that holds an element within iteration, IntelliJ idea makes a guess on the most reasonabl E names, also taking into account the name of the container being iterated.
suggestFirstVariableName(sFirstVariableName)	Doesn ' t suggest true, false, this, super .
time(sSystemTime)	Returns the current system time.
typeOfVariable(VAR)	Returns the type of the variable passed as a parameter.
underscoresToCamelCase(sCamelCaseText)	Returns the string passed as a parameter with camelhump letters substituting for underscores. For example, if the string passed as a parameter foo_bar are, then the function returns fooBar .
underscoresToSpaces(sParameterWithSpaces)	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 the is assigned to the type passed as a parameter, for example Variableoftype ("Java.util.Vecto R "). If you pass an empty string ("") as a parameter, the suggests all variables regardless of their types.
JsArrayVariable	Returns JavaScript array name.
jsClassName()	Returns the name of the current JavaScript class.
jsComponentType	Returns the JavaScript component type.
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 the index.
jsSuggestVariableName	Returns a suggested name for a variable.
