An experiment in multiple cursors for emacs. Still very much in beta.
The basic concept works, but there are definitely some kinks to work out.
This extension is dependent on the mark-multiple library.
I've set up my key-bindings like so:
;; Experimental multiple-cursors (global-set-key (kbd "C-S-c C-S-c") 'mc/add-multiple-cursors-to-region-lines) (global-set-key (kbd "C-S-c C-e") 'mc/edit-ends-of-lines) (global-set-key (kbd "C-S-c C-a") 'mc/edit-beginnings-of-lines)
To get out of multiple-cursors-mode, press
You can also switch to multiple-cursors-mode by pressing C-g when in mark-multiple-mode. This is symmetrical to how pressing C-g with an active region deactivates it. Press C-g again to remove extra cursors.
There's plenty wrong with this implementation still. I'm actively trying things out, and also working on combining it with mark-multiple.el to get a more comprehensive tool.
Still, if you've got something to contribute, please do not hesitate to open an issue, and we can take a look together before you dive into the elisp. :-)
You'll find the repo at:
Right now you can go from multiple marks to multiple cursors with C-g.
The other way around is a bit more tricky:
- What to do about overlapping marks?
- Expanding the marks should be possible, for instance using
- Killing or copying needs to keep a kill-ring for each cursor.
mark-multiple isn't ready for prime time as a full blown multiple
marks library. For this to work as expected, I think parts of mark-multiple
needs to be rewritten, and possibly integrated into multiple-cursors.
For now, mark-multiple is an excellent tool to place your cursors where you need them to be.
