# minimatch

使用glob表达式 (opens new window)的方式来判断文件是否匹配的工具，类似于正则表达式。

# 匹配规则

  • * 匹配0到多个字符
  • ? 匹配一个字符
  • ** 匹配0到多个子目录，递归匹配子目录
  • ! 在模式的开头用于否定一个匹配模式(即排除与模式匹配的信息)
  • {} 允许使用一个逗号分割的列表或者表达式
  • [...] 匹配一个字符列表，类似正则表达式的字符列表
  • !(pattern|pattern|pattern) 反向匹配括号内的模式
  • ?(pattern|pattern|pattern) 匹配0或1个括号内的模式
  • +(pattern|pattern|pattern) 匹配至少1个括号内的模式
  • *(pattern|pattern|pattern) 匹配0到多个括号内的模式
  • @(pattern|pat*|pat?erN) 精确匹配括号内的模式

# 用法

# minimatch(path, pattern, options)

var isJS = minimatch(file, "*.js", { matchBase: true })

var minimatch = require("minimatch")

minimatch("bar.foo", "*.foo") // true!
minimatch("bar.foo", "*.bar") // false!
minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!

# minimatch.filter(pattern, options)

Returns a function that tests its supplied argument, suitable for use with Array.filter. Example:

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.

var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))

# minimatch.makeRe(pattern, options)

根据pattern生成正则表达式。

# Options

All options are false by default.

注：配置很多，没有都列出来

# 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.
