ParseCsv

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/parse_csv. To experiment with that code, run bin/console for an interactive prompt.

TODO: Delete this and the text above, and describe your gem

Installation

Add this line to your application's Gemfile:

gem 'parse_csv'

And then execute:

$ bundle

Or install it yourself as:

$ gem install parse_csv

Usage

To use ParseCsv define your own class which inherits from ParseCsv::Parser. In this class, define expected columns like below

class StatementParser < ParseCsv::Parser
  column :date,        :date,    '%Y-%m-%d',             'Statement date'
  column :id,          :integer, /\A\[0-9]+\z/,          'Operation ID'
  column :description, :custom,  /\A.+\z/,               'Description'
  column :value,       :float,   /\A[0-9]+(\.[0-9]+)\z/, 'Transaction value', ->(v) { v.to_f.round(2) } }
end

column method takes four arguments:

• column name
• column type (one of integer, float, date, or custom)
• format, as date format string for :date, regexp for other types
• header (optional)
• transformation proc (optional)

Development

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
