ruby_danfe

Ruby DANFE

It generates PDF files for Brazilian DANFE (Documento Auxiliar da Nota Fiscal Eletrônica) from a valid NF-e XML.

It also generates Brazilian DACTE (Documento Auxiliar do Conhecimento de Transporte Eletrônico).

This project is inspired on NFePHP class.

Installing

    gem install ruby_danfe

Usage

If you have the xml saved in a file:

    require "ruby_danfe"
    RubyDanfe.generate("sample.pdf", "sample.xml")
    RubyDanfe.generate("cte.pdf", "cte.xml", "dacte")
    RubyDanfe.generate("cteos.pdf", "cteos.xml", "dacteos")

If you have the xml in a variable:

    xml = "string xml"
    pdf = RubyDanfe.generatePDF(xml)
    pdf.render_file "output.pdf"

You can use some options too! In this example, the product's field quantity will be rendered with 4 decimals after comma:

    xml = "string xml"
    RubyDanfe.options = {"quantity_decimals" => 4}
    pdf = RubyDanfe.generatePDF(xml)
    pdf.render_file "output.pdf"

If you have some especific option that is global for your project, you can create a file at config/ruby_danfe.yml, then the ruby_danfe always will load this options. Example:

    project_name/config/ruby_danfe.yml

    ruby_danfe:
      options:
        quantity_decimals: 3
        numerify_prod_qcom: false

Development

Installing dependencies

You can install all necessaries dependencies using bunder like above:

    $ bundle install

Tests

Manual tests

At test folder you will find the generate.rb file. It shows how to generate a pdf file from a valid xml.

You can use it following the steps above:

    $ cd test
    $ ruby generate.rb nfe_with_ns.xml
    $ ruby generate.rb cte_with_ns.xml 'dacte'
    $ ruby generate.rb cteos_with_ns.xml 'dacteos'

You can also use an special version of irb with all classes pre-loaded. Just use:

    $ rake console
    RubyDanfe.generate("output.pdf", "test/nfe_with_ns.xml")
    RubyDanfe.generate("output.pdf", "test/cte.xml", 'dacte')
    RubyDanfe.generate("output.pdf", "test/cteos.xml", 'dacteos')

or

    $ rake console
    my_xml_string = ""
    file = File.new("test/nfe_with_ns.xml", "r")
    while (line = file.gets)
        my_xml_string = my_xml_string + line
    end
    file.close

    xml = RubyDanfe::XML.new(my_xml_string)
    pdf = RubyDanfe.generatePDF(xml)

    pdf.render_file "output.pdf"

Automated tests with RSpec

You can run all specs using:

    $ rspec

In the spec/fixtures folder, you are going to find some xml files. Each one represent a different NF-e context.

Each xml file must have its respective pdf file.

If you did some change that caused general visual changes at output pdfs, so you have to rebuild all fixtures pdf files.

You can do this automagically running the following taks:

    $ rake spec:fixtures:recreate_pdfs

Code coverage

Code coverage is available through of SimpleCov. Just run rspec and open the coverage report in your browser.

Building and publishing

You can build using one of the above tasks

    $ rake build    # Build ruby_danfe-X.X.X.gem into the pkg directory
    $ rake install  # Build and install ruby_danfe-X.X.X.gem into system gems
    $ rake release  # Create tag vX.X.X and build and push ruby_danfe-X.X.X.gem to Rubygems
