CLion 2023.2 Help

Language Injection Settings dialog: Generic JavaScript

The dialog opens when you click the Add button and choose Generic JS from the context menu, or select an entry and click the Edit button.




The name of the injection.


The language to be injected.

  • ID. The language ID or name.

  • Prefix. A sequence of characters to be added before the corresponding string value.

  • Suffix. A sequence of characters to be added after the corresponding string value.

The prefix and suffix are optional.

Places Pattern

In this field, type the rules that define the context where you want CLion recognize literals as injections.


In this area, specify additional settings to narrow the context where the injection is applicable and thus to enable more fine-grained control over the injection process.

  • Value pattern - in this field, type a regular expression that determines the context to inject the language into. By using the first capturing group of the patterns as the target for injection, you can configure the procedure to have the language injected only into values that match a certain pattern or into multiple parts that match the pattern. For example, ^javascript:(.*) matches the javascript protocol that can be used in hyperlink-hrefs to execute JavaScript code.

  • Single file - If the option is off, the fragments that match the value pattern are treated separately, as different "files" - for example from the fragment editor's viewpoint.

    If the option is on, the corresponding fragments are all merged together to form a single unit, or "file".

    Given the value pattern

    xxx (.+) yyy (.+) zzz

    and the fragment

    xxx select * yyy from family zzz,

    select * and from family are treated as two independent fragments (or "files") if the option is off. If the option is on, select * from family is treated as a single unit or "file".
