= positional

Formats and/or parses positional field lists like: 'GCTACTGCAAGTTCTAGACT' or '1 8 15 22 60 55 57 56 58 55 60 58 57 59 55 50 44 18 5 6'

The input to the formatter ond the output of the parser can be any Ruby obhect. A simple mapping to Array-like objects and a more general mapping to objects with attributes corresponding to the field list are provided. The more general mapping takes a format object which is an array of attribute names.

Eg. [:temp, :pressure, :flow_rate, :rpm, :message] might correspond to a field list of '32.0 189 10000 450 "Ok"'

An class of : class InOrOut attr_accessor :temp, :pressure, :flow_rate, :rpm, :messag end

Could be used with the formatter or parser.

== Installation

sudo gem install positional

== Usage require 'pp' require 'positional' require 'in_or_out'

obj = InOrOut.new obj.temp = 32.0

... more attribute settings

parsing

arry=Array.new 20 pb = Positional::MaskedParse.new arry.extend Positional::Decorator::Index pq = Positional::Parse.new obj.extend Positional::Decorator::Message

arry = pb.parse 'GCTACTGCAAGTTCTAGACT' obj = pq.parse '32.0 189 10000 450 "Ok"', [:temp, :pressure, :flow_rate, :rpm, :message]

p arry pp obj

formatting

pf = Positional::MaskedFormat.new arry qf = Positional::Format.new obj

puts pf.to_s puts qf.to_s [:temp, :pressure, :flow_rate, :rpm, :message]

Produces: ["G", "C", "T", "A", "C", "T", "G", "C", "A", "A", "G", "T", "T", "C", "T", "A", "G", "A", "C", "T"]

== Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
