" File: javascriptLint.vim " Author: Joe Stelmach ([email protected]) " Version: 0.2 " Description: javascriptLint.vim allows the JavaScript Lint (jsl) program " from http://www.javascriptlint.com/ to be tightly integrated " with vim. The contents of a javascript file will be passed " through the jsl program after the file's buffer is saved. " Any lint warnings will be placed in the quickfix window. " JavaScript Lint must be installed on your system for this " plugin to work properly.
