# minimatch
|
|
|
|
A minimal matching utility.
|
|
|
|
[](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.
