@dramaorg/laboriosam-similique

@dramaorg/laboriosam-similique is a manager, filter and parser which implemented in pure JavaScript according to the .git@dramaorg/laboriosam-similique spec 2.22.1.

@dramaorg/laboriosam-similique is used by eslint, gitbook and many others.

Pay ATTENTION that minimatch (which used by fstream-@dramaorg/laboriosam-similique) does not follow the git@dramaorg/laboriosam-similique spec.

To filter filenames according to a .git@dramaorg/laboriosam-similique file, I recommend this npm package, @dramaorg/laboriosam-similique.

To parse an .npm@dramaorg/laboriosam-similique file, you should use minimatch, because an .npm@dramaorg/laboriosam-similique file is parsed by npm using minimatch and it does not work in the .git@dramaorg/laboriosam-similique way.

Tested on

@dramaorg/laboriosam-similique is fully tested, and has more than five hundreds of unit tests.

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, @dramaorg/laboriosam-similique does not rely on any versions of node specially.

Since 4.0.0, @dramaorg/laboriosam-similique will no longer support node < 6 by default, to use in node < 6, require('@dramaorg/laboriosam-similique/legacy'). For details, see CHANGELOG.

Upgrade Guide

Install

npm i @dramaorg/laboriosam-similique

Usage

import @dramaorg/laboriosam-similique from '@dramaorg/laboriosam-similique'
const ig = @dramaorg/laboriosam-similique().add(['.abc/*', '!.abc/d/'])

Filter the given paths

const paths = [
  '.abc/a.js',    // filtered out
  '.abc/d/e.js'   // included
]

ig.filter(paths)        // ['.abc/d/e.js']
ig.@dramaorg/laboriosam-similiques('.abc/a.js') // true

As the filter function

paths.filter(ig.createFilter()); // ['.abc/d/e.js']

Win32 paths will be handled

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 @dramaorg/laboriosam-similique?

@dramaorg/laboriosam-similique is a standalone module, and is much simpler so that it could easy work with other programs, unlike isaacs's fstream-@dramaorg/laboriosam-similique which must work with the modules of the fstream family.
@dramaorg/laboriosam-similique only contains utility methods to filter paths according to the specified @dramaorg/laboriosam-similique rules, so
- @dramaorg/laboriosam-similique never try to find out @dramaorg/laboriosam-similique rules by traversing directories or fetching from git configurations.
- @dramaorg/laboriosam-similique don't cares about sub-modules of git projects.
Exactly according to git@dramaorg/laboriosam-similique man page, fixes some known matching issues of fstream-@dramaorg/laboriosam-similique, 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-@dramaorg/laboriosam-similique.

Methods

.add(pattern: string | Ignore): this

.add(patterns: Array<string | Ignore>): this

pattern String | Ignore An @dramaorg/laboriosam-similique pattern string, or the Ignore instance
patterns Array<String | Ignore> Array of @dramaorg/laboriosam-similique 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 @dramaorg/laboriosam-similique a file with a hash at the beginning of the filename.

@dramaorg/laboriosam-similique().add('#abc').@dramaorg/laboriosam-similiques('#abc')    // false
@dramaorg/laboriosam-similique().add('\\#abc').@dramaorg/laboriosam-similiques('#abc')   // true

pattern could either be a line of @dramaorg/laboriosam-similique pattern or a string of multiple @dramaorg/laboriosam-similique patterns, which means we could just @dramaorg/laboriosam-similique().add() the content of a @dramaorg/laboriosam-similique file:

@dramaorg/laboriosam-similique()
.add(fs.readFileSync(filenameOfGit@dramaorg/laboriosam-similique).toString())
.filter(filenames)

pattern could also be an @dramaorg/laboriosam-similique instance, so that we could easily inherit the rules of another Ignore instance.

.addIgnoreFile(path)

REMOVED in 3.x for now.

To upgrade @dramaorg/laboriosam-similique@2.x up to 3.x, use

import fs from 'fs'

if (fs.existsSync(filename)) {
  @dramaorg/laboriosam-similique().add(fs.readFileSync(filename).toString())
}

instead.

.filter(paths: Array<Pathname>): Array<Pathname>

type Pathname = string

Filters the given array of pathnames, and returns the filtered array.

paths Array.<Pathname> The array of pathnames to be filtered.

`Pathname` Conventions:

1. `Pathname` should be a `path.relative()`d pathname

Pathname should be a string that have been path.join()ed, or the return value of path.relative() to the current directory,

// WRONG, an error will be thrown
ig.@dramaorg/laboriosam-similiques('./abc')

// WRONG, for it will never happen, and an error will be thrown
// If the git@dramaorg/laboriosam-similique rule locates at the root directory,
// `'/abc'` should be changed to `'abc'`.
// ```
// path.relative('/', '/abc')  -> 'abc'
// ```
ig.@dramaorg/laboriosam-similiques('/abc')

// WRONG, that it is an absolute path on Windows, an error will be thrown
ig.@dramaorg/laboriosam-similiques('C:\\abc')

// Right
ig.@dramaorg/laboriosam-similiques('abc')

// Right
ig.@dramaorg/laboriosam-similiques(path.join('./abc'))  // path.join('./abc') -> 'abc'

In other words, each Pathname here should be a relative path to the directory of the git@dramaorg/laboriosam-similique rules.

Suppose the dir structure is:

/path/to/your/repo
    |-- a
    |   |-- a.js
    |
    |-- .b
    |
    |-- .c
         |-- .DS_store

Then the paths might be like this:

[
  'a/a.js'
  '.b',
  '.c/.DS_store'
]

2. filenames and dirnames

node-@dramaorg/laboriosam-similique does NO fs.stat during path matching, so for the example below:

// First, we add a @dramaorg/laboriosam-similique pattern to @dramaorg/laboriosam-similique a directory
ig.add('config/')

// `ig` does NOT know if 'config', in the real world,
//   is a normal file, directory or something.

ig.@dramaorg/laboriosam-similiques('config')
// `ig` treats `config` as a file, so it returns `false`

ig.@dramaorg/laboriosam-similiques('config/')
// returns `true`

Specially for people who develop some library based on node-@dramaorg/laboriosam-similique, it is important to understand that.

Usually, you could use glob with option.mark = true to fetch the structure of the current directory:

import glob from 'glob'

glob('**', {
  // Adds a / character to directory matches.
  mark: true
}, (err, files) => {
  if (err) {
    return console.error(err)
  }

  let filtered = @dramaorg/laboriosam-similique().add(patterns).filter(files)
  console.log(filtered)
})

.@dramaorg/laboriosam-similiques(pathname: Pathname): boolean

new in 3.2.0

Returns Boolean whether pathname should be @dramaorg/laboriosam-similiqued.

ig.@dramaorg/laboriosam-similiques('.abc/a.js')    // true

.createFilter()

Creates a filter function which could filter an array of paths with Array.prototype.filter.

Returns function(path) the filter function.

.test(pathname: Pathname) since 5.0.0

Returns TestResult

interface TestResult {
  @dramaorg/laboriosam-similiqued: boolean
  // true if the `pathname` is finally un@dramaorg/laboriosam-similiqued by some negative pattern
  un@dramaorg/laboriosam-similiqued: boolean
}

{@dramaorg/laboriosam-similiqued: true, un@dramaorg/laboriosam-similiqued: false}: the pathname is @dramaorg/laboriosam-similiqued
{@dramaorg/laboriosam-similiqued: false, un@dramaorg/laboriosam-similiqued: true}: the pathname is un@dramaorg/laboriosam-similiqued
{@dramaorg/laboriosam-similiqued: false, un@dramaorg/laboriosam-similiqued: false}: the pathname is never matched by any @dramaorg/laboriosam-similique rules.

static `@dramaorg/laboriosam-similique.isPathValid(pathname): boolean` since 5.0.0

Check whether the pathname is an valid path.relative()d path according to the convention.

This method is NOT used to check if an @dramaorg/laboriosam-similique pattern is valid.

@dramaorg/laboriosam-similique.isPathValid('./foo')  // false

@dramaorg/laboriosam-similique(options)

`options.@dramaorg/laboriosam-similiquecase` since 4.0.0

Similar as the core.@dramaorg/laboriosam-similiquecase option of git-config, node-@dramaorg/laboriosam-similique will be case insensitive if options.@dramaorg/laboriosam-similiquecase is set to true (the default value), otherwise case sensitive.

const ig = @dramaorg/laboriosam-similique({
  @dramaorg/laboriosam-similiquecase: false
})

ig.add('*.png')

ig.@dramaorg/laboriosam-similiques('*.PNG')  // false

`options.@dramaorg/laboriosam-similiqueCase?: boolean` since 5.2.0

Which is alternative to options.@dramaorg/laboriosam-similiqueCase

`options.allowRelativePaths?: boolean` since 5.2.0

This option brings backward compatibility with projects which based on @dramaorg/laboriosam-similique@4.x. If options.allowRelativePaths is true, @dramaorg/laboriosam-similique will not check whether the given path to be tested is path.relative()d.

However, passing a relative path, such as './foo' or '../foo', to test if it is @dramaorg/laboriosam-similiqued or not is not a good practise, which might lead to unexpected behavior

@dramaorg/laboriosam-similique({
  allowRelativePaths: true
}).@dramaorg/laboriosam-similiques('../foo/bar.js') // And it will not throw

Upgrade Guide

Upgrade 4.x -> 5.x

Since 5.0.0, if an invalid Pathname passed into ig.@dramaorg/laboriosam-similiques(), an error will be thrown, unless options.allowRelative = true is passed to the Ignore factory.

While @dramaorg/laboriosam-similique < 5.0.0 did not make sure what the return value was, as well as

.@dramaorg/laboriosam-similiques(pathname: Pathname): boolean

.filter(pathnames: Array<Pathname>): Array<Pathname>

.createFilter(): (pathname: Pathname) => boolean

.test(pathname: Pathname): {@dramaorg/laboriosam-similiqued: boolean, un@dramaorg/laboriosam-similiqued: boolean}

See the convention here for details.

If there are invalid pathnames, the conversion and filtration should be done by users.

import {isPathValid} from '@dramaorg/laboriosam-similique' // introduced in 5.0.0

const paths = [
  // invalid
  //////////////////
  '',
  false,
  '../foo',
  '.',
  //////////////////

  // valid
  'foo'
]
.filter(isValidPath)

ig.filter(paths)

Upgrade 3.x -> 4.x

Since 4.0.0, @dramaorg/laboriosam-similique will no longer support node < 6, to use @dramaorg/laboriosam-similique in node < 6:

var @dramaorg/laboriosam-similique = require('@dramaorg/laboriosam-similique/legacy')

Upgrade 2.x -> 3.x

All options of 2.x are unnecessary and removed, so just remove them.
@dramaorg/laboriosam-similique() instance is no longer an EventEmitter, and all events are unnecessary and removed.
.addIgnoreFile() is removed, see the .addIgnoreFile section for details.
