Hello, It would be a great idea to include bash completion for crystal: https://github.com/crystal-lang/crystal/blob/master/etc/completion.bash
Added bash completion as: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=73bcce3cc36404063e0e8898bfc0d9df93355df4 The whole change is only: --- crystal-0.23.0.ebuild 2017-06-30 08:08:06.885722308 +0100 +++ crystal-0.23.0-r1.ebuild 2017-07-04 21:24:00.715189837 +0100 @@ -5,3 +5,3 @@ -inherit multiprocessing toolchain-funcs +inherit bash-completion-r1 multiprocessing toolchain-funcs @@ -97,2 +97,4 @@ fi + + newbashcomp etc/completion.bash ${PN} } Thank you!
