Tree-sitter injection not working

[John-Toohey]

Hi! I am working with Lilypond files using tree-sitter-lilypond. I have written highlight queries that highlight nearly all of the code, except for the scheme DSL --- which I was hoping to implement through an injection:

Here is an image of the highlighting as it stands (notice the scheme code after the # is not highlighted:

For reference here is what I would expect the scheme code to render like (having put it in a scheme file):

Now, consider this example:

\version "2.24.4"

#(set-global-staff-size 24)

who has the following tree:

(lilypond_program
    (escaped_word)
    (string "\""
      (string_fragment) "\"")
    (embedded_scheme
      (embedded_scheme_prefix)
      (embedded_scheme_text
        (scheme_list "("
          (scheme_symbol)
          (scheme_number) ")"))))

using the following injection:

(embedded_scheme (embedded_scheme_text) @injection.content
 (#set! injection.language "scheme"))

I would excpect the highlighting to work; but it does not. So, what is wrong in my query?

Thanks in advance for any help!

You may need to set (#set! injection.include-children) since the embedded_scheme_text node has children nodes underneath it. By default children nodes are excluded from injected text but with injection.include-children set the entire node captured with @injection.content will be re-parsed

I can confirm that following your advice as such has solved my issue:

(embedded_scheme (embedded_scheme_text) @injection.content
 (#set! injection.language "scheme")
 (#set! injection.include-children))
