This is an adaption of the EmacsKillRing for Sublime Text 2. It was created for the ST2 alpha, so it may need some adjustments to work with the final release.
I don’t know who the original author is, but (s)he did most of the hard work, I mostly adapted the code to conform to the new API and added region highlighting when a mark has been set.
Please note that I am not very familiar with Python, so there may be extremely silly bugs. I’d be happy to include your improvements.
Copy EmacsKillRing.py to your Packages/User folder, then add some key-bindings for the new commands, like so:
{ "keys": ["ctrl+w"], "command": "expand_selection", "args": {"to": "word"} },
{ "keys": ["ctrl+k"], "command": "emacs_kill_line" },
{ "keys": ["ctrl+y"], "command": "paste" },
{ "keys": ["ctrl+space"], "command": "emacs_set_mark" },
{ "keys": ["ctrl+w"], "command": "emacs_kill_to_mark" },
{ "keys": ["alt+w"], "command": "emacs_kill_ring_save" },
{ "keys": ["ctrl+g"], "command": "cancel_mark" }
There is a small gotcha here: I have set up ctrl+w to select the current word, like in TextMate, but that doesn’t fit well with the default Emacs key bindings, where ctrl+w means kill-region. So there is a simple check in EmacsKillRing.py which switches between these two behaviors, based on whether a mark has been set. If a mark has been set, do kill-region. If not, do expand_selection. For me, this works quite well, but it would of course be much better to use contexts for this. Please get in touch if you know how to create a custom context in a plugin.
