CSV++

CSV++ takes a <DELIMITER> separated input file and a JSON format specification and turns it into Ruby Objects. See test/sample_inputs/simple.txt and test/sample_formats/simple.json for example.

Installation

Add this line to your application's Gemfile:

gem 'csvpp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install csvpp

For development of CSV++

First make sure that you have bundler and the Ruby version installed that is specified in .ruby-version. Then run:

$ bundle

Usage

CSVPP.parse(
  input: 'test/sample_inputs/simple.txt',
  format: 'test/sample_formats/simple.json'
) # => [{"v1"=>34, "line_number"=>1, "v2"=>"foobar"}, {"v1"=>99, "line_number"=>2, "v2"=>"hi  there"}]

CLI

CSV++ comes with a CLI that speaks with the Formats API.

To print a list of known formats run:

$ csvpp formats

The parse command can be used to parse an input file with a given format, either fetched from the API or from a local JSON specification file.

For example, to import some REKOLE cost data to a local sqlite DB for querying, run:

$ csvpp parse --format fk_2017 --output costs.db test/sample_inputs/fk_2017.txt

Run csvpp help parse for more details.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. 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.
