AFAICT eldoc-message-function doesn't need to be changed because it isn't called when eldoc-mode is disabled. The reason it ends up being called in your example is that M-: explicitly and unconditionally enables eldoc-mode in the minibuffer. Dmitry suggested making this behaviour conditional as a workaround, but ultimately it would probably be best to try fixing bug#27202 without messing with eldoc-mode in read--expression.

What am I missing? define-globalized-minor-mode only adds after-change-major-mode-hook, find-file-hook, and change-major-mode-hook.

The call to read-from-minibuffer in read--expression triggers change-major-mode-hook and after-change-major-mode-hook. These in turn call turn-on-eldoc-mode, which calls eldoc--supported-p, which checks the value of eldoc-documentation-function.

I tried calling emacs-lisp-mode as the FIXME suggests, but it results in a minibuffer that can't be C-g'd out of. I guess it destroys or misses some minibuffer-specific setup? So if someone can figure out how to do that properly it does sound like a good solution. ^ permalink raw reply [flat|nested] 22+ messages in thread

So this only happens in M-:. That wasn't evident from your original report. global-eldoc-mode generally shows the signatures when point is inside any defun or other def* forms, not only in the minibuffer.

Hm... eldoc-message-function is part of eldoc package and I was hoping that, by completely disabling eldoc-mode, it will revert whatever is enabled when mode is initialized from that package. I guess different views from user and developer points. But I'm happy we are on the same page regarding this ticket. > Thanks. Thanks! Sanel ^ permalink raw reply [flat|nested] 22+ messages in thread

I guess different > views from user and developer points. I don't think this is about the differences in our views: I didn't say I considered the behavior you described correct (it isn't). My point was that your original report lacked some details, which caused me to think the problem was not reproducible, because my naïve attempt to reproduce it didn't use M-:. It is important to describe the recipe in enough detail to avoid that; please do that in the future. ^ permalink raw reply [flat|nested] 22+ messages in thread
