I just updated the Atom editor (
atom.io) on my system and noticed
when I open a crystal file (
xyz.cr) with it uses Ruby syntax bindings.
Looking through their language list I don't see Crystal specifically.
This is also true with the KDE Kate editor (my primary). If you look at
the list of languages under the categories at Tools > Highlighting there
is also no Crystal (Ruby is listed under Scripts, which I use for Crystal).
It would be good to get Crystal's name on these lists, even if using Ruby's
syntax highlighting is sufficient, if for no other reason than mindshare.
I just wanted to bring this to your attention.
