Tablib is under active development, and contributors are welcome.
If you have a feature request, suggestion, or bug report, please open a new issue on GitHub. To submit patches, please send a pull request on GitHub.
Tablib was developed with a few PEP 20 idioms in mind.
- Beautiful is better than ugly.
- Explicit is better than implicit.
- Simple is better than complex.
- Complex is better than complicated.
- Readability counts.
A few other things to keep in mind:
- Keep your code DRY.
- Strive to be as simple (to use) as possible.
Tablib source is controlled with Git, the lean, mean, distributed source control machine.
The repository is publicly accessible.
git clone git://github.com/kennethreitz/tablib.git
The project is hosted on GitHub.
Git Branch Structure¶
Feature / Hotfix / Release branches follow a Successful Git Branching Model . Git-flow is a great tool for managing the repository. I highly recommend it.
- The “next release” branch. Likely unstable.
- Current production release (0.12.1) on PyPi.
Each release is tagged.
When submitting patches, please place your feature/change in its own branch prior to opening a pull request on GitHub.
Adding New Formats¶
Tablib welcomes new format additions! Format suggestions include:
- MySQL Dump
Coding by Convention¶
Tablib features a micro-framework for adding format support. The easiest way to understand it is to use it. So, let’s define our own format, named xxx.
Write a new format interface.
tablib.corefollows a simple pattern for automatically utilizing your format throughout Tablib. Function names are crucial.
title = 'xxx' def export_set(dset): .... # returns string representation of given dataset def export_book(dbook): .... # returns string representation of given databook def import_set(dset, in_stream): ... # populates given Dataset with given datastream def import_book(dbook, in_stream): ... # returns Databook instance def detect(stream): ... # returns True if given stream is parsable as xxx
Testing is crucial to Tablib’s stability. This stable project is used in production by many companies and developers, so it is important to be certain that every version released is fully operational. When developing a new feature for Tablib, be sure to write proper tests for it as well.
When developing a feature for Tablib, the easiest way to test your changes for potential issues is to simply run the test suite directly.
Jenkins CI, amongst other tools, supports Java’s xUnit testing report format. Nose allows us to generate our own xUnit reports.
Installing nose is simple.
$ pip install nose
Once installed, we can generate our xUnit report with a single command.
$ nosetests test_tablib.py --with-xunit
This will generate a nosetests.xml file, which can then be analyzed.
Every commit made to the develop branch is automatically tested and inspected upon receipt with `Travis CI`_. If you have access to the main repository and broke the build, you will receive an email accordingly.
Anyone may view the build status and history at any time.
Additional reports will also be included here in the future, including PEP 8 checks and stress reports for extremely large datasets.
Building the Docs¶
Documentation is written in the powerful, flexible, and standard Python documentation format, reStructured Text. Documentation builds are powered by the powerful Pocoo project, Sphinx. The API Documentation is mostly documented inline throughout the module.
The Docs live in
tablib/docs. In order to build them, you will first need to install Sphinx.
$ pip install sphinx
Then, to build an HTML version of the docs, simply run the following from the docs directory:
$ make html
docs/_build/html directory will then contain an HTML representation of the documentation, ready for publication on most web servers.
You can also generate the documentation in epub, latex, json, &c similarly.
Make sure to check out the API Documentation.
