Questions: Better way to highlight variable with {} in shell script

[huyhoang8398]

Is this possible to have a better highlight with treesitter for variable quoted by {} in shell script?

I'm afraid not, because Tree-sitter applies a different capture group whether the variable is between brackets or not:

When the variable is not surrounded with brackets, the capture group is @punctuation.special.bash:

However, when the variable is surrounded with brackets, the capture group is @punctuation.bracket.bash:

That is something which can only be tackled in the Tree-sitter parser, not the colorscheme.
