# ARRRRRRRRRR PM
RPM reader/writer library written in Ruby.
It aims to provide [fpm](https://github.com/jordansissel/fpm) with a way to
read and write rpms.
## Why not use librpm?
The API is quite confusing in many places, poorly documented in most. I have
reached out to some CentOS/rpm folks to see what we can do about improving that
API.
Even still, librpm has dependencies of its own. I want fpm to be able to read
and write RPMs without requiring and endless chain of dependencies and most
especially without requiring root access to get things going.
Mainly, if I try to build librpm myself, I get this: "configure: error: missing
required NSPR / NSS header" and I'm not the burden of dependency resolution on
fpm users.
## API ideas
It should be possible to do a read+modify+write on an RPM.
### Creating an RPM (proposed API)
rpm = RPM.new
# requires and conflicts
rpm.requires("name") <= "version" # Something fun-dsl-likef
rpm.requires("name", :<=, "version") # Or maybe something like this
# provides
rpm.provides("name")
# Add some files
rpm.files << path
rpm.files << path2
rpm.files << path3
# Scripts?
rpm.scripts[:preinstall](path_or_script_string)
rpm.scripts[:postinstall](path_or_script_string)
rpm.scripts[:preuninstall](path_or_script_string)
rpm.scripts[:postuninstall](path_or_script_string)
rpm.write(output_file_name)
### Reading an RPM (proposed API)
rpm = RPM.read(file)
rpm.requires # Array of RPM::Requires ?
rpm.provides # Array of 'Provides' strings?
rpm.conflicts # Array of RPM::Conflicts ?
rpm.files # Array of RPM::File ?
Maybe something like:
rpm.files.each do |file|
# Tags that are defined in rpm header tags
# fileclass filecolors filecontexts filedependsn filedependsx filedevices
# filedigests fileflags filegroupname fileinodes filelangs filelinktos
# filemodes filemtimes filerdevs filesizes fileusername fileverifyflags
#
# frankly, we don't care about most of these. Meaningful ones:
# username, groupname, size, mtime, mode, linkto
# file.io could give a nice IO-like thing that let you read the file out
# of the rpm
end
