Note: This project is working in progress.

zdict is a CLI dictionary framework mainly focus on any kind of online dictionary.
This project originally forked from, which is a CLI tool for the Yahoo! online dictionary.
After heavily refactoring the original project including:

  1. Change from Python 2 to Python 3
  2. Focus on being a flexible framework for any kind online dicitionaries, not only just a CLI tool for querying Yahoo! online dictionary.
  3. Based on an open source project skeleton.

So, we decided to create a new project.

Development & Contributing


During development, you can install our project as editable.
If you use virtualenv, you may want to create a new enviroment for zdict::

$ git clone
$ cd zdict
$ pip install -e .

Once you installed it with the command above,
just execute zdict after modification.
Don't need to install it again.

We use py.test::

$ pip install pytest pytest-cov coverage
$ python test


$ py.test

After runing testing, we will get a coverage report in html.
We can browse around it::

$ cd htmlcov
$ python -m http.server

Also, there is some configs for py.test in setup.cfg.
Change it if you need.


py.test can prompt pdb shell when your test case failed::

$ python test -a "--pdb"


$ py.test --pdb

Bug Report

Feel free to send a bug report to
Please attach the error message and describe how to reproduce the bug.
PR is also welcome.

Please use the -d/--disable-db-cache option to query before sending the bug report.
Sometimes we modify the data schema in database for a dictionary,
but the default dictionary query of zdict uses the cache in the database which may be stored within an old schema.
This might cause an error while showing the result.
Just use the -d/--disable-db-cache to update the cache in database.
