vscode-emacs-improved

This project is a fork of the popular Emacs Keymap by hiro-sun. That project is no longer active and my goal was to add meaningful additions to the project to make this extension behave more like an emacs emulator, instead of just a keymapper.

My improvements on the original project

S-expressions was the first major addition I made. This extensnion allows movement via s-expressions, and killing s-expressions. This is most effective when editing .lisp files or any LISP dialect like Clojure. Experience with other languages may vary.

Proper kill-ring: the support for kill-rings in hiro-sun's was inconsistent with the original emacs spec for the kill-ring. The kill-ring implemented in my extensnion can store the last 60 kills added to the ring. Yank-pop is also fully supported.

CUA Mode: this minor mode allows users to keep their traditional copy paste shortcuts on windows (C-c and C-v). Note that as per the spec for CUA mode, these clipboard actions are only available when a region is highlighted. Note that C-x for cut is not supported. This is because VSCode won't recognise C-x as it is the beginning of a chord (if this is wrong, feel free to make an issue on the github page).

Rectangle mode: though skeleton code exists on hiro-sun's to support rectangle mode, it was not finished. I've built on top of this solution and have implemented rectangle-kill and rectangle-yank.
