- # minimatch
-
- A minimal matching utility.
-
- [![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](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 instantiating 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.
-
- ### 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.
