Live template variables

When you expand a live template abbreviation, its variables either appear as input fields where you can type values or are replaced with values. These may be default values that you can modify or values calculated using functions.

To declare variables within templates, use the following format: $VAR$ .

In expressions, use variable names without opening and closing dollar characters $, for example, lowercaseAndDash(ComponentName).

Define each variable using an expression and provide a default value for cases when the expression fails to evaluate.

This expression may contain the following constructs:

String constants in double quotes
Names of other variables defined in a live template
with possible arguments

Configure template variables

In the Settings dialog (Ctrl+Alt+S) , go to Editor | Live Templates.
Select a template where you want to configure variables.
Specify variables in the template text and click Edit Variables.
In the Edit Template Variables dialog, you can do the following for each variable:
- Change the variable name.
- Define an expression using predefined functions.
- Specify the default value for cases when the expression fails to evaluate. The default value should be enclosed in double quotation marks, for example, "$item" or "MyBundle".
- Specify whether you want to skip the variable when prompting the user for input if the expression evaluated successfully.

Predefined template variables

PhpStorm supports the following predefined live template variables that cannot be modified:

$END$ indicates the position of the caret when the code snippet is complete, and you can no longer press Tab to jump to the next variable.
$SELECTION$ is used in surround templates and denotes the code fragment to be wrapped. After the template expands, it wraps the selected text as specified in the template. For example, if you select EXAMPLE in your code and invoke the "$SELECTION$" template via the assigned abbreviation or by pressing Ctrl+Alt+T and selecting the desired template from the list, PhpStorm will wrap the selection in double quotes as follows: "EXAMPLE".

Functions used in live template variables

The following functions can be used to define live template variables:

Function	Description
`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 a string. For example, `capitalize("name")` returns `Name`. Or you can combine it into `capitalize(camelCase("my awesome class"))` to get `MyAwesomeClass`.
`capitalizeAndUnderscore(<String>)`	Capitalizes all the letters of a string, and inserts an underscore between the parts. For example, `capitalizeAndUnderscore("FooBar")`, `capitalizeAndUnderscore("foo bar")`, and `capitalizeAndUnderscore("foo-bar")` all return `FOO_BAR`.
`clipboard()`	Returns the contents of the system clipboard.
`commentEnd()`	Returns the characters that indicate the end of a comment in the current language context. For languages with line comments, the return value is empty.
`commentStart()`	Returns the characters that indicate the start of a comment in the current language context. For languages with line comments, the return value is the start of a line comment, same as lineCommentStart().
`complete()`	Invokes code completion at the position of the variable.
`completeSmart()`	Invokes smart type completion at the position of the variable.
`concat(<String>, ...)`	Returns a concatenation of all the strings passed to the function as parameters. For example, `concat(date()," ",user())` returns the current system date and username separated with a space.
`date([format])`	Returns the current system date. By default, without a parameter, it returns the date in the current system format. To use a different format, provide a parameter according to the SimpleDateFormat specification. For example, the `date("Y-MM-d, E, H:m")` returns the date formatted as `2020-02-27, Thu, 16:11`.
`dbColumns()`	Returns a list of columns for a table or a view. The `dbColumns()` is used in context live templates (for example, `ins`). You can access context live templates by right-clicking an object and selecting SQL Scripts.
`dbObjectName()`	Returns a name of a table or a view. The `dbObjectName()` is used in context live templates (for example, `top`). You can access context live templates by right-clicking an object and selecting SQL Scripts.
`decapitalize(<String>)`	Replaces the first letter of a string with the corresponding lowercase letter. For example, `decapitalize("Name")` returns `name`.
`enum(<String>, ...)`	Returns a list of strings suggested for completion when the template expands. For example, `enum("Foo","Bar","Baz")` shows a list from which you can choose one of the specified strings.
`escapeString(<String>)`	Escapes special characters so that the result can be used in a Java string. For example, it replaces the tab character with `\t`, the newline character with `\n`, escapes the backslash as `\\`, quotes as `\"`, and so on.
`fileName()`	Returns the name of the current file with its extension.
`fileNameWithoutExtension()`	Returns the name of the current file without its extension.
`filePath()`	Returns the absolute path to the current file.
`fileRelativePath()`	Returns the current file path relative to the current project. To check what the relative path is for a given file, right-click it and select Copy Reference, or press `Ctrl+Alt+Shift+C`.
`firstWord(<String>)`	Returns the first word of the string passed as the parameter. For example, `firstWord("one two three")` returns `one`.
`groovyScript(<String>, [arg, ...])`	Executes the Groovy script passed as a string. The first argument is a string with either the text of the script or the path to the file that contains the script. The function passes other optional arguments to the script as values for `_1`, `_2`, `_3`, ..., `_n` variables. Also, you can access the current editor from inside the script using the `_editor` variable. The following example shows a `groovyScript()` function that converts a given string (the value of another variable, $MyVar$ ) to upper case letters: groovyScript("_1.toUpperCase()", MyVar) The following example shows a `groovyScript()` function that splits the selected text into words and displays them as a numbered list: groovyScript("def result = ''; _1.split().eachWithIndex { item, index -> result = result + index.next() + '. ' + item + System.lineSeparator() }; return result;", SELECTION) The last example uses the `SELECTION` predefined variable meaning you have to select text and press `Ctrl+Alt+T` (Surround with) to apply it.
`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.
`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 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 filename.
`jsSuggestIndexName()`	Returns a suggested name for an index variable from most commonly used ones: `i`, `j`, `k`, and son on. 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, PhpStorm makes a guess on the most reasonable name, taking into account the name of the container that is iterated.
`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 string into lower case and inserts n-dashes as separators. For example, `lowercaseAndDash("MyExampleName")` and `lowercaseAndDash("my example name")` both return `my-example-name`.
`phpClassName()`	Returns the short name of the current PHP class.
`phpQualifiedClassName()`	Returns the fully qualified name of the current PHP class.
`phpSuggestVariableName()`	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, PhpStorm makes a guess on the most reasonable name, taking into account the name of the container that is iterated. When using this function, you need to provide the default value for the corresponding variable in the Edit Template Variables dialog.
`regularExpression(<String>, <Pattern>, <Replacement>)`	Finds all occurrences of `Pattern` in a `String` and replaces them with `Replacement`. You can specify the pattern as a regular expression to find everything that matches it in the string. For example, the `regularExpression(NAME, "a", "b")` expression will replace any letter "a" in the $NAME$ template variable with the letter "b". You can use regexp character classes in the pattern part; for example, `regularExpression(NAME, "[a-z]", "b")` will replace any letter in the variable. If you want patterns, such as `\d` or `\w`, to be considered as regexp character classes, you have to escape the slash so that your pattern looks like `"\\d"`.
`snakeCase(<String>)`	Converts a string into snake_case. For example, `snakeCase("fooBar")` and `snakeCase("foo bar")` both return `foo_bar`.
`spaceSeparated(<String>)`	Returns the specified string with spaces as separators. For example, `spaceSeparated("fooBar")` returns `foo Bar` and `spaceSeparated("Foo_BAR")` returns `Foo BAR`.
`spacesToUnderscores(<String>)`	Replaces spaces with underscores in the string passed as the parameter. For example, `spacesToUnderscores("foo bar BAZ")` returns `foo_bar_BAZ`.
`substringBefore(<String>, <Delimeter>)`	Returns the substring up to the specified delimiter. This is helpful for removing the extensions in test file names. For example, `substringBefore(fileName(),".")` returns `component-test` if used in a file named component-test.js.
`time([format])`	Returns the current system time. By default, without a parameter, it returns the time in the current system format. To use a different format, provide a parameter according to the SimpleDateFormat specification. For example, the `time("H:m z")` returns the time formatted as `13:10 UTC`.
`timestamp()`	Returns the current time in milliseconds calculated from the January 1, 1970. For more information, refer to Unix time.
`underscoresToCamelCase(<String>)`	Transforms a string with underscores (like snake_case) into camelCase. For example, `underscoresToCamelCase(foo_bar_baz)` and `underscoresToCamelCase(FOO_BaR_baZ)` both return `fooBarBaz`.
`underscoresToSpaces(<String>)`	Transforms underscores in a string to spaces. For example, `underscoresToSpaces(foo_bar_baz)` returns `foo bar baz` and `underscoresToSpaces(FOO_BaR_baZ)` returns `FOO BaR baZ`.
`user()`	Returns the name of the current user.
