require

const ProjectDir = require('project-dir');

on NodeJS

const myProject = new ProjectDir('./', 'node_modules')

console.log(myProject.basedir); // => '/home/user/myProject'
console.log(myProject.wd); // => '/home/user/myProject'

on git repository

const myProject = new ProjectDir('./', '.git')

console.log(myProject.basedir); // => '/home/user/myProject'
console.log(myProject.wd); // => '/home/user/myProject'

make sure NodeJS with git repository

const myProject = new ProjectDir('./', ['node_modules', '.git'])

console.log(myProject.basedir); // => '/home/user/myProject'
console.log(myProject.wd); // => '/home/user/myProject'

set basename

console.log(myProject.basename); // => ['node_modules', '.git']

myProject.basename = '.git'

console.log(myProject.basename); // => '.git'

set basedir

myProject.basedir = './abcd'; // => '/home/user/myProject'
myProject.wd; // => '/home/user/myProject/abcd'

myProject.basedir = './abcd/efgh'; // => '/home/user/myProject'
myProject.wd; // => '/home/user/myProject/abcd/efgh'

set wd (working directory)

// root
myProject.wd = '/'; // => '/home/user/myProject'

// relative path
myProject.wd = 'abcd'; // => '/home/user/myProject/abcd'
myProject.wd = 'efgh'; // => '/home/user/myProject/abcd/efgh'
myProject.wd = '../'; // => '/home/user/myProject/abcd'

myProject.wd = '/aaaa'; // => '/home/user/myProject/aaaa'

resolve

myProject.wd = '/';
myProject.resolve('abcd'); // => '/home/user/myProject/abcd'

myProject.wd = '/aaaa';
myProject.resolve('bbbb'); // => '/home/user/myProject/aaaa/bbbb'

myProject.wd = '/aaaa';
myProject.resolve('/abcd'); // => '/home/user/myProject/abcd'

retrieve

myProject.retrieve('/home/user/myProject/abcd'); // => '/abcd'

myProject.retrieve('/home/user/myProject/abcd/efgh'); // => '/abcd/efgh'

myProject.retrieve('/home/user/myProject'); // => '/'

myProject.retrieve('/home/user'); // => 'null'

parse

myProject.parse('/abcd');

{
  root: '/home/user/myProject',
  names: '.git',
  wd: '/home/user/myProject',
  path: 'abcd',
  abs: '/abcd',
  realPath: '/home/user/myProject/abcd'
}

myProject.wd = '/abcd';
myProject.parse('efgh');

{
  root: '/home/user/myProject',
  names: '.git',
  wd: '/home/user/myProject/abcd',
  path: 'efgh',
  abs: '/abcd/efgh',
  realPath: '/home/user/myProject/abcd/efgh'
}

equal

myProject.wd = '/abcd'
console.log(myProject.wd); // => '/home/user/myProject/abcd'

myProject.equal('/abcd/efgh', 'efgh'); // => true
myProject.equal('/aaaa', '../aaaa'); // => true
myProject.equal('/abcd', 'abcd'); // => false

toRoot

let paths = [];
myProject.toRoot('/abcd/efgh', (curPath) => paths.push(curPath));
console.log(curPath); // => ['/abcd/efgh', '/abcd']

API

Don't confuse ProjectPath argument. It has a difference meaning with normal path. When the argument takes ProjectPath, do not use absolute path in real file system. This moudle handles root as sub directory of base directory when argument is ProjectPath.

eg. If base directory is "/home/user/abcd", the Path's "/efgh" means "/efgh" and the ProjectPath's "/efgh" means "/home/user/abcd/efgh".

constructor(<Path>, <Query>) : Search a Query matched directory from Path to root path. and set basedir.

getter/setter

basename <Query> : get/set basename for dominating file.
basedir <Path> : get/set project's base directory.
wd <Path> : get/set project's working directory.

methods

resolve(<ProjectPath>) -> <Path> : Resolving path based on basedir
retrieve(<Path>) -> <ProjectAbsPath> : Retrieving project path from absolute real path.
parse(<ProjectPath>) -> <Object> : parsing path based on basedir. below output is result of path(+ sign means path.resolve, * sign means path.relative, path means argument, others are property name).

{
	root: <basedir>,
	names: <basename>,
	wd: <wd>,
	path: <wd*path>,
	abs: <basedir*(wd+path)>,
	realPath: <wd+path>
}

equal(<ProjectPath>, <ProjectPath>) -> <boolean> : Compare with two project path is same.
toRoot(<ProjectPath>, [<Object>, ]<Function>) : Recursively access from ProjectPath to basedir and send an argument of current path to Function.
