Javascript Question

Can JSLint be configured using an external config file in the same manner as JSHint's .jshintrc?

I've been developing a lot of small web development projects in various IDEs, and find myself laboriously typing in jslint configuration headers to silence JSLint. Its warnings and errors are all valid, and I want to keep JSLint in my work cycle, but I spin up 2-3 isolated environments a day, sometimes from generators in Yeoman, other times by hand. These all end up with gripes from JSLint that require the following in every .js file:

/*jslint browser:true*/
/*global require,yada,yada,yada*/

JSHint has a wonderful feature whereby you can declare all these in a parent folder using the body of the .jshintrc file. Does JSLint have something like this? It seems like such an obvious addition, but I can find nothing like this which will work across IDEs (Visual Studio, IntelliJ, Brackets, Sublime Text,...).

I found this for .NET, but I find Visual Studio heavy for projects I might only spend a couple hours on and then throw away (

Does someone have some insight on this?

I think the quick answer is that setting global settings for every file you JSLint is the job of your IDE or favorite text editor. That is, JSLint is essentially just a big javascript file. It doesn't care about file paths, etc, and won't look for a server-wide config.

I mean, you can change the options used when JSLint is called, but that essentially reduces to the same problem you have now.

So then the question is, if you don't like Visual Studio, what tools do you use? In VS, I've used this tool and liked it a good deal. I think that's different (as in not forked or related, but I could be wrong) than the one you found. In Sublime Text, there are two. I've been using Darren Deridder's, but I get the impression that it's the less popular of the two. Etc etc.

So this isn't a javascript/JSLint question so much as a JSLint wrapper question.

It should be said that JSLint's code is very clean, and it's easy to rig up your own process using Node or something similar. I've done it with JavaScript.NET, though I'd use Node if I was doing it again.

And I'd also suggest you consider keeping the file-by-file JSLint headers. I tend to do so, and it keeps your use "excuses" to a minimum, keeping your code tighter. It's way too easy to get a giant /*global ...*/ header line, for instance, if you have a lot of shared config info. It also means that when someone else uses a "shell" tool different than yours to JSLint your files, you know they're using pretty close to your intended accepted behaviors.

So the literal answer to your question is, "No, JSLint doesn't inherently support a box-wide config file." The longer answer is, "Tell us where you do like to work." ;^)

EDIT: Debated staying out of the usual 'Hint vs. 'Lint discussion, but I will quickly say I like how you're thinking. JSLint is more draconian, but JSLinted code means something more specific than code that's been JSHinted. I won't argue that more specific means better, per se, but I will say that I see JSLint's draconian-ness to be an advantage. It might not be the only way to do something, but there's nothing that Crockford's telling you that's a bad idea, and it's nice to get familiar with those conventions. In the parlance of my times, Crockfords's not wrong, Walter.

EDIT 2: So Brackets looks like it's come a long way since I last used it. Seems to have JSLint by default.

It looks like you can set global JSLint options using the jslint.options setting in your preferences file (and there might be/have been a goal to make that a more interactive UI eventually), like this...

    "debug.showErrorsInStatusBar": false,
    "styleActiveLine": true,
    "jslint.options": { "sloppy":true, "white":true, "browser": true }

And it does allow settings at the top of the file to override these settings.

This really is approaching a golden age of text editors. I still fall back on VIm a lot, but mainly live VS and Sublime Text, with even jEdit, Coda, and PhpStorm for specific tasks. Looks like this might be my new Sublime for Node & html frontend dev. The quick CSS edit is wonderful, though bindings will complicate it. Thanks!
