# n

 My own flavour of node binary management, no subshells, no profile setup, no convoluted api, just _simple_.

## Installation

    $ npm install n

or

    $ make install

### Installing Binaries

Install a few nodes ("v" is optional), the version given becomes the active node binary once installation is complete.

    $ n 0.2.6
    $ n v0.3.3

List installed binaries:

    $ n
    
      0.2.5
    ο 0.2.6
      0.3.3

Pass some config flags to _./configure_:

    $ n 0.2.6 --debug

List installed binaries, config flags are shown:

      0.2.3 
    ο 0.2.6 --debug
      0.3.4 
      0.3.5

Use or install the latest official release:

   $ n latest

### Removing Binaries

Remove some versions:

    $ n rm 0.2.4 v0.3.0

Instead of using `rm` we can simply use `-`:

    $ n - 0.2.4

### Binary Usage

When running multiple versions of node, we can target
them directly by asking `n` for the binary path:

    $ n bin 0.3.3
    /usr/local/n/versions/0.3.3/bin/node

Execute a script with 0.3.3 regardless of the active version:

    $ n use 0.3.3 some.js

with flags:

    $ n as 0.3.3 --debug some.js

## Usage

 Output from `n --help`:

     Usage: n [options] [COMMAND] [config] 

     Commands:

       n                           Output versions installed
       n latest [config ...]       Install or activate the latest node release
       n <version> [config ...]    Install and/or use node <version>
       n use <version> [args ...]  Execute node <version> with [args ...]
       n bin <version>             Output bin path for <version>
       n rm <version ...>          Remove the given version(s)
       n --latest                  Output the latest node version available
       n ls                        Output the versions of node available

     Options:

       -V, --version   Output current version of n
       -h, --help      Display help information

     Aliases:

       -       rm
       which   bin
       use     as

## Details

 `n` by default installs node to _/usr/local/n/versions_, from
 which it can see what you have currently installed, and activate previously installed versions of node when `n <version>` is invoked again.

 Activated nodes are then installed to the prefix _/usr/local_, which of course may be altered via the __PREFIX__ environment variable.

 To alter where `n` operates simply export __N_PREFIX__ to whatever you prefer.
