Language Injection Settings dialog: Java Parameter
File | Settings | Language Injection — Java Parameter for Windows and Linux IntelliJ IDEA | Preferences | Language Injection — Java Parameter for macOS Ctrl+Alt+S
The dialog opens when you click on the Language Injections page, and choose Java Parameter from the context menu, or select an entry and click .
Use this dialog to configure language injections for Java parameters. The dialog provides the ability to make use of IntelliLang's features, if, for any reason, the injection annotations cannot be used. This mainly applies to configuring third party/library methods as well as projects that still have to use Java 1.4.
In this area, specify the language to inject and the injection context.
ID: select the ID of the language to inject.
Prefix: specify a prefix to make up the injection context.
Suffix: specify a suffix to make up the injection context.
Note that the Prefix and Suffix fields are optional.
Click and select the class of interest. As a result, the methods of the class along with their parameters are shown.
Select the parameters for which you want to enable the injection.
Specify additional settings.
Value pattern: type a regular expression for the injection context.
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".
