mozdownload

mozdownload is a python package which handles downloading of Mozilla applications.

Installation

If the tool should only be used for downloading applications we propose to install it via pip. The following command will install the latest release:

Otherwise follow the steps below to setup a development environment. It is recommended that virtualenv and virtualenvwrapper be used in conjunction with mozdownload. Start by installing these, and creating a virtualenv for the project. Then fork our repository into your own github account, and run:

API

Beside the CLI mozdownload also offers an API to be used. To create specific instances of scrapers the FactoryScraper class can be used. Here some examples:

# Create a release scraper for the German locale of Firefox 40.0.3
from mozdownload import FactoryScraper
scraper = FactoryScraper('release', version='40.0.3', locale='de')

# Create a candidate scraper for Windows 32bit of Firefox 41.0b9
from mozdownload import FactoryScraper
scraper = FactoryScraper('candidate', version='41.0b9', platform='win32')

# Create a daily scraper for the latest Dev Edition build on the current platform
from mozdownload import FactoryScraper
scraper = FactoryScraper('daily', branch='mozilla-aurora')

All those scraper instances allow you to retrieve the url which is used to download the files, and the filename for the local destination:

from mozdownload import FactoryScraper
scraper = FactoryScraper('daily')
print(scraper.url)
print(scraper.filename)

To actually download the remote file the download() method has to be called:

from mozdownload import FactoryScraper
scraper = FactoryScraper('daily')
filename = scraper.download()

Testing

To run the entire test suite to check if your changes create any errors, run tox.

If you only run very specific tests, please specify it via tox -- -k <keyword>. For example, if you are only interested in tests that look at tinderbox builds, run tox -- -k tinderbox. The -k <keyword> works for folders, filenames and even names of test methods.
