FiletypeValidation

FiletypeValidation provides an easy to use API for validating files.

Installation

Add this line to your application's Gemfile:

gem 'filetype_validation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install filetype_validation

Usage

The gem currently supports csv file validation:

FiletypeValidation.csv?(file, options)

In this call, file is either a String representing the file path or the file itself and options is a Hash that enables the user to customize their call. The options parameter currently supports these customizations:

  • :max_lines This specifies how many lines of the file the validator will use to decide whether the file is a csv. The default value is 25.

  • :headers This expects either true or false to denote whether the csv file's header will be included in the validation.

  • :file_extension If given, the gem will use this file extension instead of the one from the initialization for checking for a .csv extension. This was included in order to account for the case where files named without extensions.

The gem also supports plaintext file validation:

FiletypeValidation.plaintext?(file, options)

In this call, file is either a String representing the file path or the file itself and options is a Hash that enables the user to customize their call. The options parameter currently supports these customizations:

  • :bytes_to_read This specifies how many bytes of the start of the given file the gem will use to determine whether or not it's plaintext.

Development

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