+# ignore
+
+`ignore` is a manager, filter and parser which implemented in pure JavaScript according to the .gitignore [spec](http://git-scm.com/docs/gitignore).
+
+Pay attention that [`minimatch`](https://www.npmjs.org/package/minimatch) does not work in the gitignore way. To filter filenames according to .gitignore file, I recommend this module.
+
+##### Tested on
+
+- Linux + Node: `0.8` - `7.x`
+- Windows + Node: `0.10` - `7.x`, node < `0.10` is not tested due to the lack of support of appveyor.
+
+Actually, `ignore` does not rely on any versions of node specially.

+## Table Of Main Contents
+
+- [Usage](#usage)
+- [Guide for 2.x -> 3.x](#upgrade-2x---3x)
+- [Contributing](#contributing)
+- Related Packages
+  - [`glob-gitignore`](https://www.npmjs.com/package/glob-gitignore) matches files using patterns and filters them according to gitignore rules.
+
+## Usage
+
+```js
+const ignore = require('ignore')
+const ig = ignore().add(['.abc/*', '!.abc/d/'])
+```
+
+### Filter the given paths
+
+```js
+const paths = [
+  '.abc/a.js',    // filtered out
+  '.abc/d/e.js'   // included
+]
+
+ig.filter(paths)        // ['.abc/d/e.js']
+ig.ignores('.abc/a.js') // true
+```
+
+### As the filter function
+
+```js
+paths.filter(ig.createFilter()); // ['.abc/d/e.js']
+```
+
+### Win32 paths will be handled
+
+```js
+ig.filter(['.abc\\a.js', '.abc\\d\\e.js'])
+// if the code above runs on windows, the result will be
+// ['.abc\\d\\e.js']
+```
+
+## Why another ignore?
+
+- `ignore` is a standalone module, and is much simpler so that it could easy work with other programs, unlike [isaacs](https://npmjs.org/~isaacs)'s [fstream-ignore](https://npmjs.org/package/fstream-ignore) which must work with the modules of the fstream family.
+
+- `ignore` only contains utility methods to filter paths according to the specified ignore rules, so
+  - `ignore` never try to find out ignore rules by traversing directories or fetching from git configurations.
+  - `ignore` don't cares about sub-modules of git projects.
+
+- Exactly according to [gitignore man page](http://git-scm.com/docs/gitignore), fixes some known matching issues of fstream-ignore, such as:
+  - '`/*.js`' should only match '`a.js`', but not '`abc/a.js`'.
+  - '`**/foo`' should match '`foo`' anywhere.
+  - Prevent re-including a file if a parent directory of that file is excluded.
+  - Handle trailing whitespaces:
+    - `'a '`(one space) should not match `'a  '`(two spaces).
+    - `'a \ '` matches `'a  '`
+  - All test cases are verified with the result of `git check-ignore`.
+
+## Methods
+
+### .add(pattern)
+### .add(patterns)
+
+- **pattern** `String|Ignore` An ignore pattern string, or the `Ignore` instance
+- **patterns** `Array.<pattern>` Array of ignore patterns.
+
+Adds a rule or several rules to the current manager.
+
+Returns `this`
+
+Notice that a line starting with `'#'`(hash) is treated as a comment. Put a backslash (`'\'`) in front of the first hash for patterns that begin with a hash, if you want to ignore a file with a hash at the beginning of the filename.
+
+```js
+ignore().add('#abc').ignores('#abc')    // false
+ignore().add('\#abc').ignores('#abc')   // true
+```
+
+`pattern` could either be a line of ignore pattern or a string of multiple ignore patterns, which means we could just `ignore().add()` the content of a ignore file:
+
+```js
+ignore()
+.add(fs.readFileSync(filenameOfGitignore).toString())
+.filter(filenames)
+```
+
+`pattern` could also be an `ignore` instance, so that we could easily inherit the rules of another `Ignore` instance.
+
+### <strike>.addIgnoreFile(path)</strike>
+
+REMOVED in `3.x` for now.
+
+To upgrade `[email protected]` up to `3.x`, use
+
+```js
+const fs = require('fs')
+
+if (fs.existsSync(filename)) {
+  ignore().add(fs.readFileSync(filename).toString())
+}
+```
+
+instead.
+
+
+### .ignores(pathname)
+
+> new in 3.2.0
+
+Returns `Boolean` whether `pathname` should be ignored.
+
+```js
+ig.ignores('.abc/a.js')    // true
+```
+
+### .filter(paths)
+
+Filters the given array of pathnames, and returns the filtered array.
+
+- **paths** `Array.<path>` The array of `pathname`s to be filtered.
+
+**NOTICE** that:
+
+- `pathname` should be a string that have been `path.join()`ed, or the return value of `path.relative()` to the current directory.
+
+```js
+// WRONG
+ig.ignores('./abc')
+
+// WRONG, for it will never happen.
+// If the gitignore rule locates at the root directory,
+// `'/abc'` should be changed to `'abc'`.
+// ```
+// path.relative('/', '/abc')  -> 'abc'
+// ```
+ig.ignores('/abc')
+
+// Right
+ig.ignores('abc')
+
+// Right
+ig.ignores(path.join('./abc'))  // path.join('./abc') -> 'abc'
+```
+
+- In other words, each `pathname` here should be a relative path to the directory of the git ignore rules.
+
+Suppose the dir structure is:
+
+```
+/path/to/your/repo
+    |-- a
+    |   |-- a.js
+    |
+    |-- .b
+    |
+    |-- .c
+         |-- .DS_store
+```
+
+Then the `paths` might be like this:
+
+```js
+[
+  'a/a.js'
+  '.b',
+  '.c/.DS_store'
+]
+```
+
+Usually, you could use [`glob`](http://npmjs.org/package/glob) with `option.mark = true` to fetch the structure of the current directory:
+
+```js
+const glob = require('glob')
+
+glob('**', {
+  // Adds a / character to directory matches.
+  mark: true
+}, (err, files) => {
+  if (err) {
+    return console.error(err)
+  }
+
+  let filtered = ignore().add(patterns).filter(files)
+  console.log(filtered)
+})
+```
+
+### .createFilter()
+
+Creates a filter function which could filter an array of paths with `Array.prototype.filter`.
+
+Returns `function(path)` the filter function.
+
+****
+
+## Upgrade 2.x -> 3.x
+
+- All `options` of 2.x are unnecessary and removed, so just remove them.
+- `ignore()` instance is no longer an [`EventEmitter`](nodejs.org/api/events.html), and all events are unnecessary and removed.
+- `.addIgnoreFile()` is removed, see the [.addIgnoreFile](#addignorefilepath) section for details.
+
+****
+
+## Contributing
+
+The code of `node-ignore` is based on es6 and babel, but babel and its preset is not included in the `dependencies` field of package.json, so that the installation process of test cases will not fail in older versions of node.
+
+So use `bash install.sh` to install dependencies and `bash test.sh` to run test cases in your local machine.
