be an alcoholic, a dope fiend, a wife beater, and even a newspaperman, but if a

Ok, this patch fixes this issue plus the "open dvi/pdf files with doc-view and ps-files with ps-mode by default" issue. (See message <877ilj45zn.fsf@baldur.tsdh.de> and its follow-ups.) The only thing that remains is to find another keybinding for toggling between editing and viewing with doc-view, because ps-mode already uses `C-c C-c'. Suggestions?

No: `push' has never been a CL function: it used to be a CL macro and nowadays it's a standard ELisp macro (tho CL replaces it with a turbocharged version of it).

But then a user would need to open a document and enable d-v-m manually in order to have it (or its minor mode) activated automatically when opening another doc.

It doesn't look like a problem to me, as long as it doesn't show PS files using doc-view by default. Note that it may be simpler to setup auto-mode-alist to map *.ps to ps-mode and dvi and pdf files to doc-view-mode and then change ps-mode to activate doc-view-minor-mode explicitly and unconditionally. That will save you from defining doc-view-mode-maybe. I'd also be very happy to get rid of the doc-view-clean-auto-mode-alist monstrosity by just saying "if you're not using doc-view-minor-mode, then toggling off doc-view puts you in fundamental-mode", or if you want to be fancier, then save the previous major-mode when entering doc-view-mode (when possible) and reuse that value when exiting it (like picture-mode does).

Or maybe we should change the binding for `ps-run-clear' in ps-mode to some other key that `C-c C-c'? > I'd also be very happy to get rid of the > doc-view-clean-auto-mode-alist monstrosity by just saying "if you're > not using doc-view-minor-mode, then toggling off doc-view puts you in > fundamental-mode", I don't get you here. If someone has his buffer in d-v-m and toggles to an editing mode I can activate d-v-minor-mode unconditionally. > or if you want to be fancier, then save the previous major-mode when > entering doc-view-mode (when possible) and reuse that value when > exiting it (like picture-mode does). Ok, that sounds reasonable. And if there was no previous major mode (or it was doc-view-mode) I can fall back to fundamental mode. I'll implement those changes later today.

Thanks for playing: the code tries the case-non-folded name first and only if that one fails, does it fallback to case-folding, so the above examples all work correctly. I.e. enabling auto-mode-case-fold only changes the behavior in the case where the buffer would otherwise be put in fundamental-mode. So the only possible downside is if the mode chosen by auto-mode-case-fold is worse than fundamental-mode. Stefan ^ permalink raw reply [flat|nested] 38+ messages in thread

AFAICT doc-view-clean-auto-mode-alist was used when toggling to editing in order to find the major mode to use while editing. So I suggest to simply use fundamental-mode (unless you're currently using doc-view-minor-mode in which case you don't need to change the major mode). Of course, you can activate the minor-mode after putting the buffer in fundamental-mode. Stefan ^ permalink raw reply [flat|nested] 38+ messages in thread

That's ok with me, but others might think different. But someone should decide: Is loading doc-view when opening ps/pdf/dvi files ok? For opening pdf/dvi files, we want themto use doc-view by default. For PS files, we don't want doc-view to be the default mode choice, but it is ok if visiting a PS file loads doc-view. ^ permalink raw reply [flat|nested] 38+ messages in thread

It's a bit confusing to see this done in 2 places. I agree -- having parts of the variable's value come from different files will be confusing for maintenance. If an installed package that wants an item in auto-mode-alist, it should go in the defvar for auto-mode-alist. ^ permalink raw reply [flat|nested] 38+ messages in thread

C-c C-l for ps-run-c_l_ear, or C-c C-g because ps-run-clear clears the PostStript _g_raphics. In that case maybe we should rename that function to ps-mode-clear-graphics to keep the mnemonics. > ps-mode also has a C-c v binding, which violates the Emacs conventions > for major modes, so that should be changed (or just deleted). I'd delete it. A command that only messages the version of a package doesn't need a key binding. Bye, Tassilo ^ permalink raw reply [flat|nested] 38+ messages in thread

Keybindings should not include C-g since that defaults to keyboard-quit which is used for aborting things in progress (which should include key sequences). -- David Kastrup ^ permalink raw reply [flat|nested] 38+ messages in thread
