class Directory

Outline

The Directory object will be used to traverse a directory/folder tree. There are 2 methods below.

Methods	Outline
walk(dir, callback)	Even when finding a sub directory, it does NOT go into that sub directoty.
recursiveWalk(dir, callback)	When finding a sub directory, it goes into that sub directoty.
change(dir, callback)	Do something callback in dir directory.

Directory.walk()

Here is generally how to display files stored under some folder.

Directory.walk("src") { &(name)
    System.println(name);
};

Directory.recursiveWalk()

Here is how to traverse folders recursively and to display found files all.

Directory.recursiveWalk("src") { &(name)
    System.println(name);
};

Directory.change()

Here is how to work in a secified directory.

Directory.change("src") {
    // Work in "src" directory.
    System.println(name);
};

Examples

Example 1. Display files (1) by walk

Code

var result = [];
Directory.walk("build/template/theme/standard") { &(name)
    result.push(name);
};
result.sort().each { System.println(_1); };

Result

build/template/theme/standard/installer.ico
build/template/theme/standard/installer.png
build/template/theme/standard/uninstaller.ico
build/template/theme/standard/uninstaller.png
build/template/theme/standard/wizard-uninst.bmp
build/template/theme/standard/wizard.bmp

Example 2. Display files (2) by walk

Code

var result = [];
Directory.walk("build/template/theme") { &(name)
    result.push(name);
};
result.sort().each { System.println(_1); };

Result

build/template/theme/standard

Example 3. Display files by recursiveWalk

Code

var result = [];
Directory.recursiveWalk("build/template/theme") { &(name)
    result.push(name);
};
result.sort().each { System.println(_1); };

Result

build/template/theme/standard
build/template/theme/standard/installer.ico
build/template/theme/standard/installer.png
build/template/theme/standard/uninstaller.ico
build/template/theme/standard/uninstaller.png
build/template/theme/standard/wizard-uninst.bmp
build/template/theme/standard/wizard.bmp

Example 4. Directory changes by change

Code

var path = $pwd;
var dirname = path.filename();
Directory.change("..") {
    var d = $pwd / dirname;
    System.println(d == path);
};

Result

1
