LintWrapper

How it works

Well I am glad you asked ;) so currently if you want it without tinkering with
files paths and what not you should put into into the root of your project or
somewhere where the js files are desendants. Loading dependencies relative to the
location of this batch is something that I am working on currently. Solution that
currently works is to perhaps create your own makefile in the working directory
and reference jsLintWrapper in there:

lint: java -jar ../jsLintWrapper/lib/external/js.jar ../jsLintWrapper/bin/linter

Settings
There are couple of ways to specify different options such as a you individual
settings file

all of these settings can be attached as a json object in the command line

to specify relative settings file
@ “commandlineOptions={configFile: ‘conf/setting.js’}” @

to run on a single file only
@ "commandlineOptions={configFile: ‘conf/settings.js’, :singleFile: ‘one/file/of/javascript.js’} @

Probably best to add to your local rake/make/ant or what ever automation
options you use currently

jslint is awesome … but what is the best way to incorporate it into your
development environment? And how do you set it up so that your can gradually
grow your gigantic javascript library into a lintfree javascript. LintWrapper
is how we are attempting to lint the codebase for patch.com. And I would like
to extend this tool and see if any others out there have not found a suitable
jslint solution that works for large code bases.

Here is the benefits of LintWrapper

• exclusion (such as libs that are not yours)
• forgiveness day … only deal with files after a date
• ignore some js lint rules (idea snagged from jquery)
• caching … no need to check a file that is unchanged

Limitations are that it uses Rhino to run … this means that you have
to have to load up your JVM to run it … but it does do some caching so it
only checks files once and then rechecks them if there is a change.

java -jar lib/external/js.jar bin/linter

or better yet

make lint

then you can add configurations into the conf/settings.js file… this will be
modularized further into the development of this tool.

Any help or ideas are super welcome and appreciated.

Tested on?

I only have two machines that I test on mac and ubuntu netbook … works on both with no problems. I am running java 1.6.x so presumably it might just work on any machine but then again I have run into problems on two different macs running the same version of java so I wouldn’t be surprized if things got busted. If you have errors please notify me and I would be delighted to hear what solved it or I could help you troubleshoot. [email protected]

Tips and Troubleshooting

sometimes it might be good to clear out your tmp/cache folder just to make sure
that there aren’t files lurking around in error etc
