## What’s it?

ido is a command tool, it’s written in python, and you can use it to install packages or execute commands. So you can just treats it as something like brew, yum, apt-get, etc. But ido can be more easy used and extended suit for your needs.

## Features

  • Simple core
  • color command output
  • packages or commands collection should be origanize in a directory
  • Installation script file is common Python source file
  • Builtin rich functions and you can easily extend
  • Packages installation aim user home first
  • Depends files can be stored in disk depends on your installation script
  • User can make themself tool based on ido to customize their application requirements
  • Written in Python, should be support 2.6, 2.7, 3.3, 3.4

## Install

` pip install ido `

This will only include the examples packages, such as demo, etc.

## Requirement

ido need: future, colorama packages, and it’ll be installed automatically.

ido should be run in python 2.6+.

## Usage

### Simple command

` ido install demo `

demo here is a demo package used to demonstrate the ido functionalities.

### Package install script

A package should be a directory, and there should be a file named install.py. Do you can write script just with python at all.

The install.py is just a common python file, but it’ll be executed with exec(), and ido will pass some builtin variables such as:

  • BUILD The value will be ‘/tmp/ido_packages_build’, and it’ll used to compile source packages.
  • PREFIX Can be passed in command line option -p or –prefix , or defined in environment variable IDO_PREFIX, and script can use it as value of ./configure –prefix.
  • HOME Current user HOME directory.

There are also some builtin functions, objects or modules, such as:

  • Modules
    • os
    • sys
  • Functions
    • sh() Used to execute shell command, sh(‘ls’)
    • cd() Used to change current directory, cd(BUILD)
    • mkdir() Used to make directories, mkdir(‘/tmp/a/b’)
    • wget() Used to download a file from internet, wget(‘http://zlib.net/zlib-1.2.8.tar.gz’)
    • cp() Used to copy a source file(can use fnmatch to match the filename) to destination directory or file, cp(‘zlib*’, BUILD)
    • install() Used to install other package, install(‘zlib’)
    • message() Used to output colored message, message(msg, ‘error’), the second argument will be error, info, or just omitted.
  • Color Objects
    • Fore, Back, Style They are colorama objects, so you can use them directly.

### Packages Index

All packages should be saved in a directory, I called it index, and ido can search package from them. ido can support multiple source of index, the default is shipped in ido package, it’s ido/packages And ido also support other local directoires or url links, so you can pass them in command line just like:

` ido install zlib -i ~/packages ido install zlib -i https://yourname/packages (Not implemented yet) ido install zlib -i ~/packages -i https://yourname/packages `

You can also defined in environment variable IDO_PACKAGES, so the searching order is:

1. command line argument 1. environment variable 1. default ido/packages

### Command options

You can just type:

ido

to see the help messages.

### Pass variables to script

If you have some viriables and want to pass them to install script, so you can define them in command argument, just like:

` ido install zlib -Evar1=demo1 -Evar2=demo2 `

### See exception

Sometime the script will throw exceptions, but they’ll be hidden by default, and if you want to see them you can just pass -v to see them.
