Yeah. If I recall, the old sandy prototype (ugly gtk+) used Control+Shift keybindings, but they went away when I noticed terminal emulators don't report them as such. Once you press Ctrl, the next key you hit gives you one control char. That's it. Not sure it's a curses thing as much as a terminal limitation. > Another thing that i have noticed is that you can't nest keybindings.

That's definitely keep the source simpler and I'm not sure we need chain keybindings. You can define the conditions (e.g. t_mod) and get it to do a different thing depending on whether the file has been modified or not (somewhat close to what Ctrl-Q does right now). If in need, you can write your own t_ function real easy.

I'm not even sure all embedded libc variants have a regex engine (maybe bionic didn't when I looked at it a while back? I don't really remember). We absolutely should get rid of a GNU dependency if possible, compile to static, use a saner curses implementation if there is any. > In fact, i dont think an editor should not allow you to edit a file because > a highlight regexp does not compiles :) I would make this silently fail.

I should probably try to get my hands on a BSD box to try these things. Maybe using libc's regcomp/regexec was not that realiable after all.

Well, if there is a suckless framework (gods, do I hate that word!), be it "slcurses", or a suckless X toolkit really, to write a text-only program, I'd be glad to find time and port sandy to that. Writing the framework itself is probably out of my scope right now, sadly. >>> * Remove utf8 enable/disable option. or make it compile-time option-only >>> (-u >>> flag) >>> - I think nowadays all our apps should be utf8 ready >> >> Will do.

I'll drop the flag, declare isutf8 a const and let everyone figure it out.

Now that you mention it, that was the main reason for printing spaces and tabs!!! I hate it when trailing spaces go unnoticed. Both control chars and space/tab fill-ins are printed in their own colour each so you can distinguish them from the characters proper. If anybody likes this (I found it cute, but it is not really that useful) then we could keep it and print \n too. Otherwise it goes and make our life simpler. Please keep in mind that right now those fill-in chars don't go to the selection as that is handled internally via xsel. They do go there if you select with the mouse skipping the xterm mouse interface (e.g. by holding Shift). Not really gracious. > yeah, dmenu is great, but I dont think it should be the default method for a > console text editor.. because it's aimed to run in a terminal, not > necesarily in X11. > > suckless programs that use dmenu are somewhat linked to X11 (dwm, surf, ..) Well, the default config does not call dmenu if DISPLAY is not set, but instead cleans the first line, prints a prompt and reads before updating the screen. A while back I tried to create a dmenu clone for console, but soon figured out there is no way to discern between stdin for options and keyboard input proper, so I just left it. Did you say you have something like that? How do you separate input? Maybe you are right and we should have a routine to read a line from inside sandy. >> I too have mixed feelings about this.

I'll try to stick with the UNIX defaults, fill in with Emacs when in doubt and remove META when possible. > as i said in my previous mails ^HJKL is not possible, so we should think in > a non-hjkl form because ^J is also handled as \n, so you can't make ^J just > move the cursor down. :/// stupid terminals. Yeah, almost makes me want to go back to gtk+.... almost :) Btw, how does emacs handle this? I haven't really used the monstrosity, but I recall they do different in ^J and Ret. Or is that in their GUI version only? Anybody using emacs kind enough to check? > I would like to have the minimum possible keybindings configured by default. > Maybe we can meet in irc to discuss it, mailing list discussion for this can > take too much time. Sure, I will drop them from the default list now and push the changes once the repo is hosted at suckless.

I'll take a quick look at the quote regexes now, but since I don't really know which are working where :S I hope nothing bad comes out of this. > In VIM i use a lot the '%' key to move between matching parenthesis, > brackets,...

You seem to have great ideas and I sincerely hope you can contribute some code :) Best regards, Rafa.
