intellij-idea Little-known features Language injection
Example
If you want to write strings containing other languages (JSON, regexes), it's hard to keep up with escaping symbols, and it would be nice to get some code assist.
- Put your cursor inside an empty string
ALT + ENTER- Pick "Inect language or reference"
- Pick the desirable language (
RegExpin my case) from the pop-up
- Again use
ALT + ENTERand pickEdit regex fragment
- In the new tool window enter the regex - note how it's automatically mapped to a properly escaped Java string. Similarly for JSON the indents will be placed properly.
