Node dirutils

Overview

dirutils is a simple module for Node.JS which adds methods to the process object which mimic the behavior of pushd, popd, and dirs in unix-like systems. The methods provided by this module are pushdir, popdir, and dirs. The first two methods are named to match the naming of chdir which is provided by Node.JS.

Usage

To use dirutils just install it with npm install dirutils and require it with require('dirutils'). There is no need to save the result of require('dirutils') to a variable as there are no exports from this module, it adds methods directly to the process object.

pushdir

The pushdir method changes to the directory passed as its first argument and places that directory on top of the directory stack. For example:

// Go into the `lib` directory relative to the current working directory.
process.pushdir('lib');

// Go to the absolute path `/bin` process.pushdir('/bin');

// Go to the user's home directory process.pushdir(process.env.HOME);

The pushdir method can also accept a number argument (integers only, no decimals) indicating an index in the stack to change the current working directory to. The directory at that index is moved to the top of the stack.

popdir returns the current stack as a mutable array. This should only be used for reference and even though you can change the array, it is highly recommended that you do not.

popdir

The popdir method removes the directory on the top of the stack and then changes into the directory now on top of the stack. It also optionally accepts an optional number argument indicating which index in the stack to remove -- the current working directory will not change when a directory is removed from the stack in this fashion.

// Continuing the example above (in the user's home directory) process. //
Remove `/bin` from the directory stack. process.popdir(2); // Go into the
`lib` directory: process.popdir(); // Go into the original starting
directory: process.popdir();

popdir returns the current stack as a mutable array. This should only be used for reference and even though you can change the array, it is highly recommended that you do not.

dirs

Takes an optional boolean argument indicating to reset the stack. If you call process.dirs(true) the stack will be reinitialized with the current working directory as the only value on the stack.

Regardless of if a boolean is passed in or not, dirs returns the current stack as a mutable array. This should only be used for reference and even though you can change the array, it is highly recommended that you do not.

Running the Tests

To run the tests, you must have testem and mocha installed globally:

npm i -g testem mocha

Once those are installed, you should run npm install from this project's root directory. Once that is done you can run testem or npm test to run the tests.
