Bug 338550 – app-emacs/company-mode failed to complete python symbols because of missing backend dependencies

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Yang Zhang 2010-09-24 13:24:53 UTC]

app-emacs/company-mode failed to complete in python mode even with ropemacs USE. The problem turned out that company-mode use ropemacs for python completion but there are no dependencies on ropemacs. There are no dev-python/ropemacs in portage, neither.

To be correct, company-mode should depend on dev-python/ropemacs & app-emacs/pymacs when the "ropemacs" USE flag is on.

Created attachment 248509 [details]
company-mode-0.5-r1.ebuild

The modified ebuild:
Added dev-python/ropemacs in RDEPEND

See the comment in the company-mode ebuild:
# Note: company-mode supports many backends, and we refrain from including
# them all in RDEPEND. Only depend on things that are needed at build time.

It's fine to add ebuilds for packages that are supported by company-mode's backends, as in the depending bugs. But we won't add them as dependencies.

Hi, firstly thanks very much for your reply. I totally agree with the fact that it will be too complicated to add all dependencies for company-mode. But I suspect that if it is right to include a dependency which would not function correctly.

The "ropemacs" USE flag pulls in a dependency (app-emacs/pymacs) but it does not work at all! An ordinary user (me for example) would expect to add "ropemacs" to make python completion work, but it doesn't. I think it is better to pull in direct dependency on dev-python/repomacs or we just remove the "repomacs" USE flag so the user does not get confused when finding it not work. It is even better if we can issue a elog describing the situation.

We can add ropemacs as run-time dependency, but we must wait for the ~amd64 keyword in bug 339633.

Thanks. Sorry that I have no amd64 access.
