Emacs: subword-mode, superword-mode, camelCase, snake_case
subword-mode. It change all cursor movement/edit commands to stop in-between the “camelCase” words.
superword-mode (emacs 24.4) is similar. It treats text like “x_y” as one word. Useful for “snake_case”.
superword-mode are mutally exclusive. Turning one on turns off the other.
To see whether you have subword-mode on, Alt+x
describe-variable then type “subword-mode”. Same for superword-mode.
To turn it on, just call
subword-mode. Call again to turn off.
Or put in emacs init file:
;; move cursor by camelCase (subword-mode 1) ; 1 for on, 0 for off
