Live templates

By using Live templates, you can insert frequently-used constructions into your code. For example, loops, conditions, various declarations, or print statements. To expand a code snippet, type the corresponding template abbreviation and press Tab. Keep pressing Tab to jump from one variable in the template to the next one. Press Shift+Tab to move to the previous variable. For more information, see Live template variables.

live template example

The following types of live templates are distinguished:

  • Simple templates contain only fixed plain text. When you expand a simple template, the text is automatically inserted into your source code, replacing the abbreviation.

    Abbreviation

    Expands to

    psfs
    public static final String
    psvm
    public static void main(String[] args){ }
    sout
    System.out.println();
  • Parameterized templates contain variables that enable user input. When you expand a parameterized template, variables are either replaced by input fields for the user to specify manually, or calculated by MPS automatically.

    Abbreviation

    Expands to

    fori
    for (int i = 0; i < ; i++) { }
    ifn
    if (var == null) { }
    ifn
    if (var == null) { }
  • Surround templates wrap a block of the selected code with the text specified by the user. For example, T expands into a pair of tags, for which you can specify a name. You can also select a block of code, then press Ctrl+Alt+J to open the Select Template popup and select the T template to wrap the selection with a pair of tags.

To configure live templates, open the Editor | Live Templates page of MPS settings (Ctrl+Alt+S). On the Live Templates page, you can see all the available live templates, edit them and create new templates. Templates are grouped according to the context where they can be used (usually, by the corresponding language). To move a template to another group, right-click the template, select Move, and then select the necessary group name.

Each live template is defined by an abbreviation containing alphanumeric characters, dots, and hyphens. The abbreviation must be unique within a group, but the same abbreviation may be used in different groups and expand to different constructs according to the context of the corresponding group. Abbreviations of modified default templates are shown in the list with blue font.
