VIMFIDDLER

See https://github.com/mharju/vim-fiddle for a similar project (but I believe Mac only).

Requirements

Selenium
Vim with python 2 support (check with :python print "hello")
The selenium Python driver (included)
For jslint integration, a working jslint command (on my system, I use node.js + npm install jslint -g)
A web server to host the fiddles (for instance apache)

Features

A "fiddle" consists of a index.html file and a code.js file
When either file is saved, vimfiddler refreshes the browser (via selenium)
jslint integration, hit F4 to jslint the current file.

Installation

Unpack vimfiddler in ~/public_html (or use a symbolic link)
You need Selenium Server from http://seleniumhq/download/
On my system, the command selenium starts the selenium server. If your system is different, edit fiddler.vim
On my system, the command jslint starts jslint, if your system is different, edit fiddler.vim.
Edit fiddler.vim to use a different browser. The default is *firefox. Use *googlechrome to use Chrome.

Start vim

In Vim:

Use template: default

When either code.js or index.html is saved, Vim will tell selenium to refresh the page.
