Creating and Editing Template Variables
On this page:
- Configuring variables used in a template
- Predefined functions to use in live template variables
After a template is expanded, its variables are presented in the editor as input fields. The values of these fields can be either filled in by the user or calculated by CLion.
To have it done automatically, for each variable you need to specify the following:
- Expression to be calculated in association with the variable.
- Default value to be entered in the input field if the calculation fails.
The order in which CLion will process input fields after the template expansion, is determined by the order of variables in the list.
Configuring variables used in a template
Open the template settings, and in the Template Text area
click the Edit Variables button.
The Edit Template Variables dialog box opens, where you can define how the variables will be processed when the template is used.
- In the Name text box, specify the variable name to be used in the template body.
- In the Expression drop-down list, specify the expression to be calculated by
CLion when the template is expanded. Do one of the following:
- Type a string constant in double quotes.
- Type a predefined function with possible arguments or select one from the drop-down list.
An argument of a function can be either a line constant or another predefined function. See the list of predefined functions below on this page.
- To enable CLion to proceed with the next input field, if an input field associated with the current variable is already defined, select the Skip if defined check box.
- To arrange variables in the order you want CLion to switch between associated input fields, use the Move Up and Move Down buttons.
Predefined functions to use in live template variables
|Returns the string passed as a parameter, converted to camel case. For example,
|Capitalizes the first letter of the name passed as a parameter.|
|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 |
|This expression substitutes for the class name completion at the variable position.|
|Returns the contents of the system clipboard.|
|Returns CamelCase string out of snake_case string. For example, if the string passed as a parameter is
|This expression substitutes for the code completion invocation at the variable position.|
|This expression substitutes for the smart type completion invocation at the variable position.|
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:
|Replaces the first letter of the name passed as a parameter with the corresponding lowercase letter.|
|List of comma-delimited strings suggested for completion at the template invocation.|
|Escapes the specified string.|
|Returns file name with extension.|
|Returns file name without extension.|
|Returns the first word of the string passed as a parameter.|
|Returns the current line number.|
|Returns lower case separated by dashes, of the string passed as a parameter. For example, the string
|Returns a list of visible objects that contain the member functions, listed as parameters.|
|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.|
|Returns snake_case string out of CamelCase string passed as a parameter.|
|Returns string separated with spaces out of CamelCase string passed as a parameter. For example, if the
string passed as a parameter is |
|Suggests the name of an index variable. Returns |
|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, CLion makes a guess on the most reasonable names, also taking into account the name of the container being iterated.
|Doesn't suggest |
|Returns the current system time.|
|Returns the string passed as a parameter with CamelHump letters substituting for underscores.
For example, if the string passed as a parameter is |
|Returns the string passed as a parameter with spaces substituting for underscores.|
|Returns the name of the current user.|
|Returns a variable that is an instance of object used as a range-expression in a loop.|
|Returns a variables that is an instance of object that contain |
