Local Application Port System

Local Application Management system. This application just like MacPorts on Mac OS X. An application has some versioned. But we use various version case by case. For example Ruby application is now moving from 1.8 to 1.9. So we must build Ruby 1.8 and Ruby 1.9 environment. And so, we use many many middle ware, memcached, redis, MySQL, Varnish... localport make us build multiversion environment easyly.

Install

Just easy. Just type,

$ gem install localport

How to use

There is some restrictions, following:

When you install some application, you must specify one directory. This directory is called "application directory" on system. Like this,
```
~/apps
```
And, you must specify execute directory. This directory is called "executional directory" Like this,
```
~/local/bin
```

Ok, Let's control Ruby-1.8.7.-p160 with localport.

Build, and Install Ruby-1.8.7-p160 to "application directory".

$ tar zxvf ruby-1.8.7-p160.tar.gz
$ cd ruby-1.8.7-p160
$ ./configure --prefix=$HOME/apps/ruby/1.8.7-p160

Install that to "execution directory"
```
$ localport install ~/apps/ruby/1.8.7-p160
```
This command make symbolic links that are Ruby applications in
```
~/apps/ruby/1.8.7-p160/bin/*
```

Then, Activate that.

$ localport activate ruby-1.8.7-p160

This command make installed symbolic ruby-1.8.7-p160 point symbolic link.

$ ls -l ~/local/bin/ruby -> ~/local/bin/ruby-1.8.7-p160
$ ls -l ~/local/bin/ruby-1.8.7-p160 -> ~/apps/ruby/1.8.7-p160/bin/ruby

Deactivate that. If you want to execute another Ruby version with no specified version command, 'ruby'.
```
$ locaport deactivate ruby-1.8.7-p160
```
This command remove symbolic link 'local/bin/ruby'.

Commands

This application provide some commands. Like MacPorts.

install
installed
activate
deactivate
update

install

To specify an application path.

$ localport install {app}

installed

To list up installed applications.

$ localport installed [app]

activate

To activate installed application.

$ localport activate {app}

deactivate

To deactivate installed application. Delete internal symbolic link.

$ localport deactivate {app}

update

Rubygems will install with gem command after localport controlled. Some $RUBY/bin/exec will be installed but didn't create symbolic link. So, update command create symbolic link for these execution files.

$ localport update {app}
