jslint

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

When running my JavaScript through JSLint, I get the following two errors from the same line of code. Problem at line 398 character 29: Insecure '.'. if (password.match(/.[!,@,#,$,%,^,&,*,?,_,~,-,(,)]/)) Problem at line 398 character 41: Unescaped '^'. if (password.match(/.[!,@,#,$,%,^,&,*,?,_,~,-,(,)]/)) I understand that JSLint may be being "over-cautious". I read the comments on a similar question, Purpose of JSLint "disallow insecure in regex" option . Nonetheless, I would like to have the best of all worlds, and have a working regular expression that also doesn't cause JSLint to complain.

In my javascript I have this loopDeLoop: while (foo !== bar) { switch (fubar) { case reallyFubar: if (anotherFoo == anotherBar) { break loopDeLoop; } break; default: break; } } But JSLint says... lint warning: use of label Here's the notes from JSLint Labels JavaScript allows any statement to have a label, and labels have a separate name space. JSLint is more strict. JSLint expects labels only on statements that interact with break: switch, while, do, and for. JSLint expects that labels will be distinct from vars and parameters. How do I construct the above to get rid of the warning? Thanks,

I have a code block like this: /*global MYAPP: true*/ var MYAPP = MYAPP || {}; JSLint highlights "MYAPP" after equal sign with message "MYAPP used out of scope". What's wrong with that? If you use var then you are declaring a local variable. If you do MYAPP || {} then you are typically trying to set a default value for a global variable, or for a variable declared earlier. What is the scope of MYAPP supposed to be? If it is global, then something like MYAPP = window.MYAPP || {}; window. stops it from complaining that it is undefined If it is not global but declared earlier, then MYAPP = MYAPP

JSLint seems to be picky about function ordering. This passes fine: function a() { 'use strict'; return 1; } function b() { 'use strict'; a(); } While this gives an 'a' is out of scope error message: function b() { 'use strict'; a(); } function a() { 'use strict'; return 1; } Is this by design? Should I care? How can it be avoided in larger (more complex) cases, where it might not always be possible to give the functions a clear order? Juan Mendes JSLint/JSHint expect you to define functions before you reference them. However, JavaScript doesn't care because functions and variables are hoisted

There is a problem during Rally App SDK 2.0p environment setup on Windows 7 (64-bit). I have installed Ruby 1.8.7-p358 from rubyinstaller.org and managed to install rake Ruby gem. But I have problems installing jslint-v8 gem. It has dependencies on therubyracer and libv8 gems which need to be built using Ruby DevKit. During the installation I got the following error: C:\ruby> gem install jslint-v8 Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing jslint-v8: ERROR: Failed to build gem native extension. C:/ruby/bin/ruby
