Backspace in insert-mode seems to not be working

[rieje]

I visually select a block of text, then narrow it. I do grm to mark the strings. When I type some characters, the typed characters are reflected in all cursors as expected. However, if I backspace to delete a character, it only deletes the character from the current line (the line with the real cursor).

If I use vim/evil's X to delete the character in visual mode, it deletes it in all lines (so is working properly). So just backspace in insert mode is not working.

Are there any errors in the messages buffer? I wonder if there's a conflict with some minor mode or backspace is running some command overwritten by the major mode that you're in. What major mode are you in when you experience this behavior? Does the same happen in the fundamental mode?

[rieje]

It happens even if I don't narrow it. Before and after. There are no errors in the messages buffer--only thing related to evil-mc is evil-mc Created 5 cursors matching "\_<setq\_>".

I was in Emacs Lisp mode and it does not happen in fundamental mode. Let me know how I can diagnose this, I'm an emacs noob.

Can you run describe-key and press backspace. See what command it is bound to. On my system that's bound to evil-backward-char

[rieje]

DEL (translated from \<backspace>) runs the command evil-backward-char (found in evil-normal-state-map),

[gabesoft]

Hmm, then it should work. Try running evil-mc-executing-debug-on and backspace again while there are multiple cursors. See if there's any evil-mc output in the messages buffer.

The culprit appears to be hungry-delete. If I disable the mode. Not sure exactly what is causing it though...

[gabesoft]

Oh, I'm glad that you figured it out. I'll add a fix for hungry-delete shortly.
