One of the issues people raised with moving the non-block/function/class specific documentation from Doxygen to this wiki is that people won't have a local copy of the Usage Manual anymore. To solve this I put together a little script that exports a list of pages on this wiki to the raw source which looks almost exactly the same as the doxygen source. This script just has to be run a few times a year and then the resulting files committed to gnuradio git (the location of these files within the git repo has yet to be determined).

To use this script, you will have to download geckodriver and change the line that points to where it is located. After running it there should be a new directory called "Usage Manual" created in whatever directory you ran the script from, containing a bunch of text files.

  1. Download latest version of geckodriver from here and extract it to a known location, then modify the line "driver = webdriver.Firefox(..." below (I've had the best luck with v0.21)
  2. sudo pip install selenium HTMLParser
  3. Make sure the two versions match, see this table

Note that this script now also exports the Blocks Docs pages
