A More Ergonomic Keybinding for Flycheck in Doom Emacs
Doom Emacs uses spacebar keybindings for maximum efficiency and comfort, but flycheck was missed. If you deal with a lot of code errors, this might save you from RSI.
I rely on flycheck a lot for giving me hints on type errors when I’m writing TypeScript, but in Doom Emacs the flycheck commands are still bound to C-c !
. Since I don’t have flycheck configured to run ’live’ on every code change (for performance reasons) I found myself pressing C-c ! c
manually all the time, which became physically painful. But I think I’ve found a good rebinding that stays in line with the Doom way of doing things.
I’ve chosen simply to bind all of flycheck’s commands to SPC c x
instead by putting this in my config.el
.
(after! flycheck (map! :leader (:prefix-map ("c" . "code") "x" flycheck-command-map)))
The SPC c
prefix is for “code” commands, which makes sense to me—flycheck is for code checking after all. And although we’ve lost SPC c x
’s original binding to flycheck-list-errors
it’s still easily accessible now through SPC c x l
. I think x
is a great mnemonic for errors too.
Doing it this way keeps all the keys you’re familiar with under C-c !
since we just forward SPC c x
to flycheck’s original command map.
So now I happily mash SPC c x c
all day and it’s also much easier to go forward and backward through flycheck errors using SPC c x n
and SPC c x p
.
Hope this helps. Happy hacking!
