IntelliJ IDEA 2017.2 Help

Language Injection Settings dialog: Generic Groovy

File | Settings | Language Injection - Groovy



The dialog opens when you click add.png   on the Language Injections page, and choose Generic Groovy on the context menu, or select an entry and click edit1.

IntelliJ IDEA comes with a set of predefined injection configurations which is quite sufficient to ensure high productivity and comfortable environment. Therefore it is strongly recommended that you use the predefined injection configurations and avoid creating new ones.

Name The name of the injection.
Language 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. For more info, see Using language injection prefixes and suffixes.

Places Pattern In this text box, type the rules that define the context where you want IntelliJ IDEA recognize literals as injections.

The rules are built from Program Structure Interface Patterns and are actually chained calls of methods of an internal IntelliJ IDEA language. The Program Structure Interface shows the structure of a file as IntelliJ IDEA treats it.

These rules are IntelliJ IDEA internals, and it is strongly recommended that you use the predefined injection configurations and avoid creating new ones.

Advanced 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 text box, type a regular expression that determines the context to inject the language into. By using the first capturing group of the pattern 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" - e.g. 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".
