Hm, please do `M-x toggle-debug-on-error', reproduce the error and poste the backtrace. Bye, Tassilo ``` ## Rustom Mody, 2009-08-29 14:37 Subject: Re: vc in emacs problem with git Message-ID: URL: https://gitlist.dev/e/f46c52560908290737r53e0732o2b552665f9c07098%40mail.gmail.com In-Reply-To: ``` On Thu, Aug 27, 2009 at 9:44 PM, Rustom Mody wrote: > Just updating my own question: > when I do a C-x v v (vc-next-action) > which is supposed to be the most basic operation for checking in a file I get > >  Wrong type argument: stringp, nil > > So vc can be assumed to be a broken I guess? Answering my own question: Short answer: vc-git.el from git breaks vc in emacs Long answer: see emacs mailing list discussion http://groups.google.com/group/gnu.emacs.help/browse_thread/thread/657d9c58baed7b0f# ``` ## Junio C Hamano, 2009-08-29 18:41 Subject: Re: vc in emacs problem with git Message-ID: <7viqg65up7.fsf@alter.siamese.dyndns.org> URL: https://gitlist.dev/e/7viqg65up7.fsf%40alter.siamese.dyndns.org In-Reply-To: ``` Rustom Mody writes: > Just updating my own question: > when I do a C-x v v (vc-next-action) > which is supposed to be the most basic operation for checking in a file I get > > Wrong type argument: stringp, nil > > So vc can be assumed to be a broken I guess? Have you checked contrib/emacs/README? ``` ## Rustom Mody, 2009-08-30 08:54 Subject: Re: vc in emacs problem with git Message-ID: URL: https://gitlist.dev/e/f46c52560908300154k7496167l552348075cb52537%40mail.gmail.com In-Reply-To: <7viqg65up7.fsf@alter.siamese.dyndns.org> ``` On Sun, Aug 30, 2009 at 12:11 AM, Junio C Hamano wrote: > Rustom Mody writes: > >> Just updating my own question: >> when I do a C-x v v (vc-next-action) >> which is supposed to be the most basic operation for checking in a file I get >> >>  Wrong type argument: stringp, nil >> >> So vc can be assumed to be a broken I guess? > > Have you checked contrib/emacs/README? > -- Sorry Junio I should have checked. Actually I had earlier checked. Then I tried many emacs-git options, none of which worked. Then I upgraded my emacs to 23 in which the vc is upgraded for dvses like git. Time passed and I forgot what I had found, made worse by the fact that sometimes I'm on windows and sometimes on linux and the 'working' status of different things is quite different. However the point is that I was not loading the older vc-git.el at all. emacs was getting the wrong one. It may be better if vc were hardened so that it gets its own vc-*.els in preference to random stuff lying on the load-path. ```
