Syntax highlighting for html and mysql inside a php file

[razvbir]

Hi,

I'm trying to use helix for php development. I was wondering if there is anyway to get syntax highlighting for html and mysql inside a php file. I've seen a reddit thread about how to do it in vim and it seems to work out of the box on sublime text. Can it be done in helix?

You need to extend the tree-sitter injections for PHP: https://github.com/helix-editor/helix/blob/master/runtime/queries/php/injections.scm

This is my ~/.cargo/bin/runtime/queries/php/injections.scm. I don't really know Scheme. I've tried them both with no luck.

Variant 1:

((text) @injection.content
 (#set! injection.language "html")
 (#set! injection.language "sql")
 (#set! injection.combined))

((comment) @injection.content
 (#set! injection.language "comment"))

Variant 2:

((text) @injection.content
 (#set! injection.language "html")
 (#set! injection.combined))

((text) @injection.content
 (#set! injection.language "sql")
 (#set! injection.combined))

((comment) @injection.content
 (#set! injection.language "comment"))

You can't have two captures for a (text) node work; only the first capture will apply. I'm not familiar with PHP so I can't write the queries for you, but you can look at these resources:

• Query syntax
• Injections
• tree-sitter playground to see the AST for a given piece of code.

This was very helpful, thank you very much. I've kind of manage to get it working.

I'm looking for ways to improve it and I'd appreciate any hints.
