Tern for CoffeeScript plugins
Use a work around way to let tern.js play with CoffeeScript.
Requirement
Tern.js 0.6 and node environment.
Installation
Use npm to install this plugin in tern's directory.
npm install tern-coffee
For example, vim user:
cd ~/.vim/bundle/tern_for_vim
npm install tern-coffee
Then you must let your editor enable tern for CoffeeScript files. Vim user can install tern_for_vim_coffee. This is very simple plugin. You must install both tern_for_vim and tern_for_vim_coffee
Last part is .tern-project file. It's required to use a plugin. Remember
to add coffee to plugin list.
How
Marijn describes how difficult to let tern support a new language. CoffeeScript only have source map support. There is no error tolerance CoffeeScript compiler available. So this is not a perfect solution.
The walk around solution is try to fix the editing CoffeeScript file before compile to JavaScript. Ex:
obj.
Will change to
obj.__fake__
Before compile. There are more fix rules. Not perfect but should ok for normal editing.
The base of source mapping logic is by mntmn.
