Using Language Injections
On this page:
- Injecting a language into the source code and cancelling language injection
- Moving injections between the IDE and the project levels
Before you start working with language injections, make sure that IntelliLang plugin is enabled.
The plugin is bundled with PhpStorm and activated by default. If not, enable the plugin as described in Enabling and Disabling Plugins.
PhpStorm supports full coding assistance for:
When the editor recognizes a string as a language injection:
- Syntax and error highlighting and coding assistance are extended to this string.
- You can open and modify it in a separate tab in the editor,
as if you were working with the source code in the corresponding language.
To open an injection in the editor, use the Edit <Language> Fragment intention action.
Injecting a language into the source code and cancelling language injection
To tell PhpStorm that certain text should be treated as an embedded source code fragment, you can use:
- The Inject Language/Reference intention action, which is applied to a particular string:
After that, you have to select the desired language from the menu:
Note that if you use this method, it’s possible that the string literal will stay marked as a language injection only within a limited period of time. That is, PhpStorm, at a certain moment, may "forget" that the corresponding literal is a language injection. The period of the injection "persistence" will depend on the language, context and the modifications that you make in other parts of your source code.
- The Language Injections page of the Settings dialog. By creating new language injection configurations on that page, you can specify that a certain method parameter, text in an XML tag, or XML attribute should always be treated as an embedded source code fragment in another language.
To cancel language injection, choose the intention action Un-inject Language/Reference.
Moving injections between the IDE and the project levels
User-defined injections are assigned either to the IDE or the project level. The IDE-level injections are available in all of your projects. The project-level injections can be used only in the project in which they are defined.
The built-in injections are the IDE-level ones, and their scope cannot be changed.
