Is there any (good) way to inject another language into a PSI tree that doesn’t include PSI injection host elements? To provide specific context, in free (i.e., unlicensed/Community Edition) IDEs, I can easily find/detect string literals even in the absence of a first-class PSI tree, e.g., for JavaScript/TypeScript files, and for some that match well-defined, recognizable patterns, I’d like to inject the corresponding first-class language. Those files – typically either abstract file type files or TextMate files – don’t have any real PSI structure, so I was wondering if there was some way to tell the injection system that specific text ranges of the `PsiFile` itself should be treated as if they were injection hosts. Hopefully that makes sense. Let me know if not. ---

Hopefully this is not needed anymore as IntelliJ IDEA provides JS/TS PSI in free mode
