I'm developing a mode for Emacs, and everytime I switch to its buffer, viper gets turned on. I've modified viper-mode to trace where viper-mode is being called, and surprisingly set-viper-state-in-major-mode is called by running the viper-post-command-hooks, set to nil. Any idea of what is going on?
Thanks!
EDIT: For the benefit of all beings, here is what I found out: as instructed by Trey, I started emacs with -Q and manually loaded both viper and my package. As I could reproduce the bug, the problem was on one of these packages. After line-by-line filtering, I discovered that the innoquous-looking (kill-all-local-variables) was causing the problem.
There's something in initialization that's causing it.
First try starting without your .emacs emacs -q. If the problem persists, then the trigger is in the site-start.el. So, talk to whomever installed Emacs and get them to remove the customizations there. You can also always use the -Q startup option to avoid loading the site-start.el.
If the problem isn't in site-start.el, and you don't think it's in your .emacs, it might be in a custom default.el file, which you can prevent from being loaded by adding:
(setq inhibit-default-init t)
to your .emacs.
If you still have a problem, then I'm 99% sure it's in your .emacs.
To be 100% sure, try emacs -Q, which runs Emacs with no customizations. If the problem persists, download and install your own Emacs b/c you surely can't trust the installation you're using.
So, now if you're convinced it's in your .emacs, start cutting out parts of your .emacs, or introduce an error in your .emacs with (error "frog"), and progressively rule out which portions of your .emacs are causing the problem.
