Beginning line function #45
Conversation
Defines crux-smart-line-start to replace back-to-indentation. back-to-indentation moves the point to the first non-whitespace character. The new function does that for all major modes, except ansiterm and eshell, where it moves to end of the prompt. More major modes can be added. By fixing this function, crux-move-beginning-of-line is improved. prelude issue #998 "C-a broken in eshell" is fixed [1]. [1] - bbatsov/prelude#998

There was a problem hiding this comment.
Seems to me it'd be better if those were separate vars/constants and you added a check inside the function for the current mode. Btw, keep in mind that for your variable solution to work this variable has to be buffer-local, not global like it is now.
Remove variable crux-smart-line-start-regex. Add function that skips line beginning depending on mode.

I was basing my code off of the emacs function term-bol. It uses term-prompt-regexp to skip forward past the prompt. I couldn't figure out how to override C-a only in specific modes though. I like allowing the user to configure what move-to-mode-line-start skips because the regex can't match everything. Right now the term-mode regex matches repl prompts like ghci and nodejs, but not python's ">>> ". Custom emacs repl buffers can make C-a do the right thing without this pull request. |

Defines crux-smart-line-start, a new function to replace back-to-indentation.
back-to-indentation moves the point to the first non-whitespace character. The new function does that for all major modes, except ansi-term and eshell, where it moves to end of the prompt. More major modes can be added.
By fixing this function, crux-move-beginning-of-line is improved. Prelude issue #998 "C-a broken in eshell" is fixed. There were workarounds posted in that thread, but I thought a better solution was available.
