Create vim project files that open automatically with MacVim.

vimproject.js

var pathmod = require('path');

var EXTENSION = 'vimproj';

process.chdir("{PATH}");\n\

process.exit();';

function main() {

  var args = process.argv.slice(2);

      var cwd = process.cwd();
      var path = pathmod.resolve(cwd, args[0]);
      var proj, projfile, target = pathmod.resolve(cwd, args[1]);

Installation Instructions

1. Copy the script to /usr/local/bin or any directory on your $PATH
2. Open Terminal.app and on the Seetings page, set the Shell exit behaviour to "Close if the shell exited cleanly"

After you create your first project, right click on it and set it to open with Terminal.app. This will automatically open MacVim when you double click on the directories you specify.

Usage:

The following creates project.vimproj on the current directory

vimproject /path/to/your/project .

The following creates myproject.vimproj:

vimproject /path/to/your/project /output/myproject.vimproj
