JSHint is a community-driven tool to detect errors and potential problems in
JavaScript code and to enforce your team's coding conventions. It is very
flexible so you can easily adjust it to your particular coding guidelines and
the environment you expect your code to execute in. JSHint is open source and
will always stay this way.
## Our goal
The goal of this project is to help JavaScript developers write complex programs
without worrying about typos and language gotchas.
Any code base eventually becomes huge at some point, and simple mistakes—that
would not show themselves when written—can become show stoppers and waste
hours of debugging. And this is when static code analysis tools come into play
and help developers to spot such problems. JSHint scans a program written in
JavaScript and reports about commonly made mistakes and potential bugs. The
potential problem could be a syntax error, a bug due to implicit type
conversion, a leaking variable or something else.
Only 15% of all programs linted on [jshint.com](http://jshint.com) pass the
JSHint checks. In all other cases, JSHint finds some red flags that could've
been bugs or potential problems.
Please note, that while static code analysis tools can spot many different kind
of mistakes, it can't detect if your program is correct, fast or has memory
leaks. You should always combine tools like JSHint with unit and functional
tests as well as with code reviews.
## Reporting a bug
To report a bug simply create a
[new GitHub Issue](https://github.com/jshint/jshint/issues/new) and describe
your problem or suggestion. We welcome all kinds of feedback regarding
JSHint including but not limited to:
* When JSHint doesn't work as expected
* When JSHint complains about valid JavaScript code that works in all browsers
* When you simply want a new option or feature
Before reporting a bug look around to see if there are any open or closed tickets
that cover your issue. And remember the wisdom: pull request > bug report > tweet.

# minimatch
A minimal matching utility.
[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.png)](http://travis-ci.org/isaacs/minimatch)
This is the matching library used internally by npm.
It works by converting glob expressions into JavaScript `RegExp`
objects.
## Usage
```javascript
var minimatch = require("minimatch")
minimatch("bar.foo", "*.foo") // true!
minimatch("bar.foo", "*.bar") // false!
minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
```
## Features
Supports these glob features:
* Brace Expansion
* Extended glob matching
* "Globstar" `**` matching
See:
* `man sh`
* `man bash`
* `man 3 fnmatch`
* `man 5 gitignore`
## Minimatch Class
Create a minimatch object by instanting the `minimatch.Minimatch` class.
```javascript
var Minimatch = require("minimatch").Minimatch
var mm = new Minimatch(pattern, options)
```
### Properties
* `pattern` The original pattern the minimatch object represents.
* `options` The options supplied to the constructor.
* `set` A 2-dimensional array of regexp or string expressions.
Each row in the
array corresponds to a brace-expanded pattern. Each item in the row
corresponds to a single path-part. For example, the pattern
`{a,b/c}/d` would expand to a set of patterns like:
[ [ a, d ]
, [ b, c, d ] ]
If a portion of the pattern doesn't have any "magic" in it
(that is, it's something like `"foo"` rather than `fo*o?`), then it
will be left as a string rather than converted to a regular
expression.
* `regexp` Created by the `makeRe` method. A single regular expression
expressing the entire pattern. This is useful in cases where you wish
to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
* `negate` True if the pattern is negated.
* `comment` True if the pattern is a comment.
* `empty` True if the pattern is `""`.
### Methods
* `makeRe` Generate the `regexp` member if necessary, and return it.
Will return `false` if the pattern is invalid.
* `match(fname)` Return true if the filename matches the pattern, or
false otherwise.
* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
filename, and match it against a single row in the `regExpSet`. This
method is mainly for internal use, but is exposed so that it can be
used by a glob-walker that needs to avoid excessive filesystem calls.
All other methods are internal, and will be called as necessary.
## Functions
The top-level exported function has a `cache` property, which is an LRU
cache set to store 100 items. So, calling these methods repeatedly
with the same pattern and options will use the same Minimatch object,
saving the cost of parsing it multiple times.
### minimatch(path, pattern, options)
Main export. Tests a path against the pattern using the options.
```javascript
var isJS = minimatch(file, "*.js", { matchBase: true })
```
### minimatch.filter(pattern, options)
Returns a function that tests its
supplied argument, suitable for use with `Array.filter`. Example:
```javascript
var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
```
### minimatch.match(list, pattern, options)
Match against the list of
files, in the style of fnmatch or glob. If nothing is matched, and
options.nonull is set, then return a list containing the pattern itself.
```javascript
var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
```
### minimatch.makeRe(pattern, options)
Make a regular expression object from the pattern.
## Options
All options are `false` by default.
### debug
Dump a ton of stuff to stderr.
### nobrace
Do not expand `{a,b}` and `{1..3}` brace sets.
### noglobstar
Disable `**` matching against multiple folder names.
### dot
Allow patterns to match filenames starting with a period, even if
the pattern does not explicitly have a period in that spot.
Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
is set.
### noext
Disable "extglob" style patterns like `+(a|b)`.
### nocase
Perform a case-insensitive match.
### nonull
When a match is not found by `minimatch.match`, return a list containing
the pattern itself if this option is set. When not set, an empty list
is returned if there are no matches.
### matchBase
If set, then patterns without slashes will be matched
against the basename of the path if it contains slashes. For example,
`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
### nocomment
Suppress the behavior of treating `#` at the start of a pattern as a
comment.
### nonegate
Suppress the behavior of treating a leading `!` character as negation.
### flipNegate
Returns from negate expressions the same as if they were not negated.
(Ie, true on a hit, false on a miss.)
## Comparisons to other fnmatch/glob implementations
While strict compliance with the existing standards is a worthwhile
goal, some discrepancies exist between minimatch and other
implementations, and are intentional.
If the pattern starts with a `!` character, then it is negated. Set the
`nonegate` flag to suppress this behavior, and treat leading `!`
characters normally. This is perhaps relevant if you wish to start the
pattern with a negative extglob pattern like `!(a|B)`. Multiple `!`
characters at the start of a pattern will negate the pattern multiple
times.
If a pattern starts with `#`, then it is treated as a comment, and
will not match anything. Use `\#` to match a literal `#` at the
start of a line, or set the `nocomment` flag to suppress this behavior.
The double-star character `**` is supported by default, unless the
`noglobstar` flag is set. This is supported in the manner of bsdglob
and bash 4.1, where `**` only has special significance if it is the only
thing in a path part. That is, `a/**/b` will match `a/x/y/b`, but
`a/**b` will not.
If an escaped pattern has no matches, and the `nonull` flag is set,
then minimatch.match returns the pattern as-provided, rather than
interpreting the character escapes. For example,
`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
`"*a?"`. This is akin to setting the `nullglob` option in bash, except
that it does not resolve escaped pattern characters.
If brace expansion is not disabled, then it is performed before any
other interpretation of the glob pattern. Thus, a pattern like
`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
checked for validity. Since those two are valid, matching proceeds.
