I'm looking for an emacs function that will delete all whitespace from the cursor position (including newlines) until the first non-whitespace character.
For example, if my cursor is positioned at the end of the first line:
main(arg1, arg2) The delete function would result in:
main(arg1,arg2) You might find the hungry-delete package useful. I personally bind C-cdelete to delete whitespace after point, and C-cbackspace to delete whitespace before point like so
(global-set-key (kbd "C-c <backspace>") 'hungry-delete-backward) (global-set-key (kbd "C-c <deletechar>") 'hungry-delete-forward) update: as of 12.2018 function definitions changed hence:
(global-set-key (kbd "C-c <backspace>") 'c-hungry-delete-backward) (global-set-key (kbd "C-c <deletechar>") 'c-hungry-delete-forward) I use this quite often:
(defun join-line* () "Join this line with the next line deleting extra white space." (interactive) (join-line t)) (global-set-key (kbd "M-j") #'join-line*) ;; just key binding I use… 
C-u M-^. join-line (aka delete-indentation) often leaves one space character after point. C-k M-\
C-k- Kill rest of line or one or more lines(kill-line).
M-\- Delete spaces and tabs around point(delete-horizontal-space).
Yet another solution
(defun foo () (interactive) (delete-region (point) (+ (save-excursion (skip-chars-forward " \n")) (point))))
