Seth Brown’s markdown “flip links” script
-
I’m curious to know if Pythonista for iOS supports Seth Brown’s python script within the “md - flip links” workflow, posted at:
https://brettterpstra.com/projects/markdown-service-tools/#linksfliplinkstyle
I copied the python script out of the macOS workflow, saved it within Pythonista, and enabled it as a share extension shortcut. When I select the markdown text in iAWriter and launch the shortcut, nothing happens. What other tweaks do I need to make?
Thanks!
Here’s the code:

@crankygeologist some little modifications but I'm not sure I did not destroy the logic because I replace md by self.text in lines 69 and 77.
I also move the appex.get to the main

@cvp Thank you, so much. It works! Now to study your changes. ;-)
