ERB vs EMBEDDED_TEMPLATE heredocs

[powersurge360]

Hey all! I noticed in the docs the use of <<-ERB heredocs, which don't seem to support syntax highlighting within the heredoc. I know that in VSCode you can get syntax highlighting in a heredoc but I'm not 100% sure if it works for ERB. What I do know is that in neovim if you use <<-EMBEDDED_TEMPLATE instead, it gives ERB syntax highlighting. Does that work in VSCode? Any other editors? If the functionality is widespread it might be worth suggesting that rather than ERB for convenience.

I did some looking and I can't figure out which plugin is managing the syntax highlighting (I use the lunar vim distribution) but I suspect it's probably tree sitter. I wonder if it would be possible to get ERB aliased somehow in those plugins for a tidier experience.

Hey @powersurge360, thanks for asking about this and for your willingness to dig in. The docsite is generated by Jekyll, which uses the rouge gem by default. I just had a look at rouge's Ruby lexer and I don't see anything in there for syntax highlighting heredocs. It looks like it's possible to compose lexers together though. Check out how the ERB lexer does it here.

Good luck!
