ethanliew / vim.js Goto Github PK

A Tool/Toy for Non-Beginners

by Lu Wang

• Works but unstable, only tested on Firefox/Chrome + Ubuntu
• Faster on Chrome than Firefox
• Some features work better on Firefox (e.g. <Ctrl>)

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.

As we all know that there are huge number of features in Vim, but most people use only a small subset of it. So I have to try to balance the feature set and the file size, by including most common features, and also a few that I pick.

If you really want some feature(s) enabled by default, please try to compile it yourself first, estimate the increase in size and create a pull request.

• Persistent ~/.vimrc
• Execute JavaScript from Vim.js (:!)

• Prepare the dependencies:
  • emscripten
    • Use the wl branch of my fork if anything goes wrong
  • node.js
  • streamline.js
  • 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
• Prepare build.sh
  • Setup the path of emscripten inside
  • Uncomment the last few lines
• Run build.sh

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!
