|

Wikimedia dumps are usually in a compressed format such as 7z (most common), gz, or bz2. Wikiq uses your computer's compression software to read these files. Therefore wikiq depends on
|
||||
`7za`, `gzcat`, and `zcat`.
|
||||
|
||||
Dependencies
|
||||
----------------
|
||||
These non-Python dependencies must be installed on your system for wikiq and its
|
||||
associated tests to work.
|
||||
|
||||
- 7zip
|
||||
- ffmpeg
|
||||
|
||||
Tests
|

----
|
||||
To run tests::
|

|

python -m unittest test.Wikiq_Unit_Test
