Walktree

A easy to use module to convert recursive directory listing into an array or json object.

Install

npm install walktree

Usage

    var walktree = require('walktree');
    console.log(walktree.arraySync())
    // list of all files recursively (root folder: './')

Functions

    // Synchronously fetch all files in string array format
    // if no parameter is provided the default values are used.
    walktree.arraySync()
        //  output: 
        //      ['anotherFolder', 'file1.txt', 'file2.txt', 'picture1.jpg']
        
    walktree.jsonSync(): Synchronously fetch all files in string array format
        //  output:
        //      [
        //        {
        //            parent: './',
        //            name: 'anotherFolder'
        //            stats: [fsObject stats],
        //            isFile: false,
        //            isDirectory: true
        //        },
        //      {
        //            parent: './',
        //            name: 'file1.txt'
        //            stats: [fsObject stats],
        //            isFile: true,
        //            isDirectory: false
        //        },
        //        {
        //            parent: './',
        //            name: 'file2.txt'
        //            stats: [fsObject stats],
        //            isFile: true,
        //            isDirectory: false
        //        },
        //        {
        //            parent: './',
        //            name: 'picture1.txt'
        //            stats: [fsObject stats],
        //            isFile: true,
        //            isDirectory: false
        //        }
        //    ]

Options

  walktree.arraySync([
    {
        ['root': root], // String = './'
        ['junk': junk], // Boolean = false
        ['junkRegExp': junkRegExp], // RegExp = RegExp in "junk" dependency module 
        ['type': type], // String = 'filesAndFolders'
        ['recursively': recursively], // Boolean = true
        ['extended': extended], // Boolean = true
        ['filter': filter],  // Stribg = '*'
    }
  ])

####The json option is not required, in those cases "walkdir" will use the default configuration.

  1. root Is the root folder to start the walk.

        type: String
        default value: './'
        issue: in this version root can only point to current script execution directory './'
               or one of his childrens (for example './node_modules',  './views/templates',
               './scripts/bundle', etc.).
        example: 
            walktree = required('walktree')
            var w = walktree.arraySync({'root': './templates'})
            console.log(w)
            // Retrieve all files in "templates" folder (relative to the path of the 
            // caller script in your app) recursively as an array of string.
  2. junk Should we fetch junk files too? (for example ".thumbnails", ".DS_Store", etc).

        type: Boolean
        default value: false
        example: 
            walktree.arraySync({
                'root': './images', 
                junk: true 
            })
            // Retrieve all files inside "images" folder without getting thumbs.db (junk files) in the array.
  3. junkRegexp regExp field to customize the junk filter

        type: RegExp
        default value: /^npm-debug\.log$|^\..*\.swp$|^\.DS_Store|^\.AppleDouble$|^\.LSOverride$|^Icon[\r\?]?|^\._.*|^.Spotlight-V100$|\.Trashes|^__MACOSX$|~$|^Thumbs\.db$|^ehthumbs\.db$|^Desktop\.ini$/
        example: 
            walktree.arraySync({
                'root': './', 
                junkRegexp: /^.idea$|^.git$/
            })
  4. type Modality of the walk, retrieve files and folders, only files or only folders

        type: String
        default value: 'filesAndFolders'
        possible values: 'files' | 'folders' | 'filesAndFolders'
        example: 
            walktree.arraySync({
                'root': './', 
                'type': 'files'
            })
            // Retrieve only files
  5. recursively boolean: default = true; should we look inside every folder too?

        type: Boolean
        default value: true
        example: 
            walktree.arraySync({
                'recursively': false
            })
            // Retrieve only files in the folder specified but in the sub folders. In this
            // case because no folder is specified in the parameters, the folder that will 
            // be used is './'
  6. extended Should we retrieve detailed properties of each file? (like isFile and isFolder)

        type: Boolean
        default value: true
        example: 
            walktree.jsonSync({
                'extended': false
            })
            // Set it to false if you want to return the json structure with only "parent", 
            // "name" and "stat" fields.
  7. filter RegExp | wildcard string default: '*'

    var walktree = require('walktree');
    
    var w = walktree.jsonSync(
        {
            root: './templates'
          , filter: '*.html'
      //  , junk: true
        }
    );
    // will show only html files inside template folder. If you have more than one filter
    // you can use curly braces to separate them of example: 
    walktree.jsonSync(
        {
            root: './templates'
          , filter: '{*.html}{*.js}{*.css}'
        }
    );
    // This usage of filter will retrieve all html, javascript and cascade style files.
