GH syntax highlighing


Didn’t know where exactly to ask this. I noticed GitHub’s syntax highlighting of crystal has an issue with the %|my string| format for pipe-delimited percent string literals.

See this example:

Seems like only pipe has the issue. How does the community manage the syntax highlighting?

According to Github’s linguist repo¹ they use this here for crystal syntax highlighting:

You might want to file an issue (or better send a PR) there. A couple of member of the crystal-lang-tools organization on GH are here on this forum as well. They might be able to help you out if needed.

Awesome, thanks for the reference. The issue doesn’t appear in Atom for me using the latest package. github/linguis says:

Grammars are updated every time we build the Linguist gem so upstream bug fixes are automatically incorporated as they are fixed.

So that tells me it should be fixed eventually.
