ItemDescription
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.
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".
