# multiple-cursors.el
|
|
|
|
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.
|
|
|
|
https://github.com/magnars/mark-multiple.el
|
|
|
|
## Usage
|
|
|
|
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 `C-g`.
|
|
|
|
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.
|
|
|
|
## Contribute
|
|
|
|
There's plenty wrong with this implementation still. I'm actively trying things
|
|
out, and also working on combining it with
|
|
[mark-multiple.el](https://github.com/magnars/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:

## Combining with mark-multiple
|
|
|
|
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 `mark-word` or
|
|
`expand-region`
|
|
* Killing or copying needs to keep a kill-ring for each cursor.
|
|
|
|
So basically `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.
