# WARNING

This is an alpha release! There is still work to be done

# Quickstart

## Working with RPM package files

```ruby
require 'rpm'

pkg = RPM::Package.open("file.rpm")
pkg.arch => "x86_64"

pkg.files.each do |file|
  puts file.path
end

pkg.changelog.each do |entry|
  puts "#{entry.name} #{entry.time} #{entry.text}"
end
```

## Querying the rpm database

```ruby
require 'rpm'

RPM.transaction do |ts|
  ts.each do |pkg|
    puts pkg
  end
end
```

## Install a package

```ruby
require 'rpm'

pkg = RPM::Package.open('foo.rpm')

RPM.transaction(rootdir) do |t|
  t.install(pkg, 'foo.rpm')
  t.commit
end
```

## Introduction

This library is a replacement for the ruby-rpm gem, originally
writen by Kenta Murata around 2002 for the Kondara distribution. Later
mantained by David Lutterkort and myself.

Why?

* The original gem supports ancient rpm versions not in use anymore
* The original gem was written in C using MRI API
* The #ifdef'ing required to support multiple rpm versions made the code
  hard to maintain

This gem:

* Is pure ruby
* Is documented
* Has as a goal to support only the latest rpm version plus the ones in 
  use some releases back in popular rpm based distros
* Uses FFI, so it should work with other interpreters
  (Because https://github.com/rubinius/rubinius/issues/682 it currently does
  not work on Rubinius)
* Does not target rpm5, but it may support it someday

As an example the code that implements RPM::Package was reduced
from 1130 lines of code to 320.

# Architecture

The gem is divided in two modules:

* RPM::C:: which contains the 1:1 mapping to the librpm API
  Not all functions are attached, only the ones we actually use.
* RPM:: contains the actual higher level API

# Status, Compatibility and Differences with ruby-rpm

* Only rpm 4.11.x or later will be supported
* You can use symbols: instead of RPM::TAG_DESCRIPTION you
  can use just :description. 'rpm/compat' is by default loaded
  and provides compatibility with the RPM::TAG_* style constants
* RPM::DB is not supported. Use RPM::Transaction
* Spec and Source classes are not implemented yet

## TESTING

Unit tests can be run using the `rake test` command.

### Docker tests

In order to not damage your system, you can run the testsuite under docker:

* Build the docker images:

```console
rake docker_images
```

* Run the testsuite under Docker

```console
rake docker_test
```

## TODO

* Check Package#signature should return String?
    => ruby-rpm seems to return symbol
* Food for thought: Package dependencies and changelog
  methods could just use []. Calling headerGet directly saves
  us from doing one iteration per attribute
* Not sure if Spec can be implemented as it was before with
  newer rpms.
