" File: javascriptLint.vim " Author: Joe Stelmach (joe@zenbe.com) " Version: 0.1 " 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.
