docxgen

Docxgen is a Ruby library for templating docx files based on ruby-docx.

• Validates if there is any variables without provided values
• Supports arrays
• Preserves formatting
• Supports non-latin variable names (cyrillic, for example)

Ruby 2.4+

Add this line to your application's Gemfile:

gem "docxgen"

And then execute:

bundle install

Or install it yourself as:

gem install docxgen

Example of variables and corresponding hashes:

# {{ hello }} => world

{ hello: "world" }

# {{ hello.world }} => wow

{ hello: { world: "wow" } }

# {{ array.0.name }} => Wow

{ array: [ { name: "Wow" } ]}

# {{ Привет.Мир }} => 123

{ "Привет": { "Мир": "123" } }

generator = Docxgen::Generator.new("template.docx")

generator.render({ variable: "Value" }, remove_missing: true)

Options:

remove_missing [default: true] - Replaces variables without provided values with empty string

generator.valid? # Returns true if there is no errors

puts generator.errors # Returns array of the errors

generator.save("result.docx")

Alternatively you can use stream method if you want to get result as StringIO (for example, for saving it in ActiveStorage):

io = generator.stream

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