Bug 526266 – dev-haskell/cabal-install: bash-completion installed under incorrect name

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Michał Górny 2014-10-21 15:36:58 UTC]

* Problems with installed bash completions were found:
 * 
 * 	cabal-install: incorrect name, no completions for 'cabal-install' command defined.
 * 	cabal: missing alias (symlink) for completed command.
 * 
 * For more details on installing bash-completions, please see:
 * https://wiki.gentoo.org/wiki/Bash/Installing_completion_files

Long story short, it should be installed as 'cabal' rather than 'cabal-install'.

I'm all for fixing it, but it's unclear what exactly and which version started to require it.

[Comment 2 Michał Górny 2014-10-21 20:59:16 UTC]

You need to change:

    newbashcomp "${S}/bash-completion/cabal" ${PN}

to:

    dobashcomp "${S}/bash-completion/cabal"

Since that's how the executable is named. It became necessary since bash-completion-2.0 prerelease (I think that was named 1.90) upstream and will become necessary with 2.1-r90 in Gentoo.

The change is backwards compatible. However, users of old bash-completion versions will need to re-enable the completion due to name change. You may want to do it in a revbump and add the revbump to the bash-completion-2.1-r90 mask.

Yes, of course. Forgot to close the bug, sorry.
