Contributing¶ ↑
Contributions to mime-types-data is encouraged in any form: a bug report, new MIME type defintions, or additional code to help manage the MIME types. As with many of my projects, I have a few suggestions for improving the chance of acceptance of your code contributions:
-
The support files are written in Ruby and should remain in the coding style that already exists, and I use hoe for releasing the mime-types-data RubyGem.
-
Use a thoughtfully-named topic branch that contains your change. Rebase your commits into logical chunks as necessary.
-
Do not change the version number; when your patch is accepted and a release is made, the version will be updated at that point.
-
Submit a GitHub pull request with your changes.
-
New or changed behaviours require new or updated documentation.
Although mime-types-data was extracted from the Ruby mime-types gem and the support files are written in Ruby, the target of mime-types-data is any implementation that wishes to use the data as a MIME types registry, so I am particularly interested in tools that will create a mime-types-data package for other languages.
Adding or Modifying MIME Types¶ ↑
The Ruby mime-types gem loads its data from files encoded in the
data
directory in this gem by loading
mime-types-data
and reading MIME::Types::Data::PATH. These
files are compiled files from the collection of data in the
types
directory. Pull requests that include changes to these
files will require amendment to revert these files.
New or modified MIME types should be edited in the
appropriate YAML file under types
. The format is as shown
below for the application/xml
MIME
type in types/application.yml
.
- !ruby/object:MIME::Type content-type: application/xml encoding: 8bit extensions: - xml - xsl references: - IANA - RFC3023 xrefs: !ruby/hash:MIME::Types::Container rfc: - rfc3023 registered: true
There are other fields that can be added, matching the fields discussed in the documentation for MIME::Type. Pull requests for MIME types should just contain the changes to the YAML files for the new or modified MIME types; I will convert the YAML files to JSON prior to a new release. I would rather not have to verify that the JSON matches the YAML changes, which is why it is not necessary to convert for the pull request.
If you are making a change for a private fork, use rake
convert:yaml:json
to convert the YAML to JSON, or rake
convert:yaml:columnar
to convert it to the new columnar format.
Updating Types from the IANA or Apache Lists¶ ↑
If you are maintaining a private fork and wish to update your copy of the MIME types registry used by this gem, you can do this with the rake tasks:
$ rake mime:iana $ rake mime:apache
Development Dependencies¶ ↑
mime-types-data uses Ryan Davis’s Hoe to manage the release process, and it adds a number of rake tasks. You will mostly be interested in:
$ rake
which runs the tests the same way that:
$ rake test $ rake travis
will do.
To assist with the installation of the development dependencies for
mime-types-data, I have provided the simplest possible Gemfile pointing to
the (generated) mime-types-data.gemspec
file. This will permit
you to do:
$ bundle install
to get the development dependencies. If you aleady have hoe
installed, you can accomplish the same thing with:
$ rake newb
This task will install any missing dependencies, run the tests/specs, and generate the RDoc.
You can run tests with code coverage analysis by running:
$ rake test:coverage
Workflow¶ ↑
Here's the most direct way to get your work merged into the project:
-
Fork the project.
-
Clone down your fork (
git clone git://github.com/<username>/mime-types-data.git
). -
Create a topic branch to contain your change (
git checkout -b my_awesome_feature
). -
Hack away, add tests. Not necessarily in that order.
-
Make sure everything still passes by running
rake
. -
If necessary, rebase your commits into logical chunks, without errors.
-
Push the branch up (
git push origin my_awesome_feature
). -
Create a pull request against mime-types/mime-types-data and describe what your change does and the why you think it should be merged.
