Vim.js : JavaScript port of Vim

A Tool/Toy for Non-Beginners

by Lu Wang

Try it online

Status

• Works but unstable, only tested on Firefox/Chrome + Ubuntu
• Faster on Chrome than Firefox
• Some features work better on Firefox

Features

vim.js is built with the small feature set (--with-features=small), with also a few from the normal set. Run :version to check.

--with-features=normal is too large and too slow for online usage.

Instructions for hackers

• Prepare the dependencies:
  • emscripten
  • node.js
  • streamline.js
  • closure compiler
  • GCC & cproto (maybe)
    • Sometimes you need to run make proto when you see errors about 'undeclared variables/functions/structs'
• Get yourself familiar with everything above and also:
  • source code of vim
  • JavaScript, and also HTML/CSS
• Setup paths in build.sh
• Uncomment the last few lines in build.sh
• Run build.sh

Development

Patches are welcome and wanted for

• Wrapping async functions — learn more
• Multi-browser/platform support
• Stability improvements
• UI improvements
• Other stuffs in TODO

If you want to work on other features to be merged, please file an issue and discuss with me first.

Do not override vim.js or build.sh!
