Support cmarkgfm 0.8

[gustaphe]

I'm having the same issue that was solved by #209 , but for 'cmarkgfm>=0.8.0. I wouldn't know how to test things because I don't know python, but presumably the same change as that PR should do the trick.

Hi @gustaphe, what exactly is the issue you're having?

Running plover from package plover-git, with package plover_plugins_manager installed on Arch Linux, gives this error message

2022-04-26 10:27:56,648 [MainThread] ERROR: error loading gui.qt.tool plugin: plugins_manager (from plover_plugins_manager.gui_qt.manager)

pkg_resources.ContextualVersionConflict: (cmarkgfm 0.7.0 (/usr/lib/python3.10/site-packages), Requirement.parse('cmarkgfm>=0.8.0'), {'readme-renderer'})

The AUR listing for the latter package has a previous issue with the same error, which spawned #209. I have no insight into what drives the requirements race on the other end. Sorry if this is X/Y.

Unfortunately I don't think there's anything we can do here, whatever is installing cmarkgfm=0.7.0 alongside the latest version of readme-renderer needs updated to install cmarkgfm>=0.8.0 instead. Sorry but I'm not familiar enough with the Arch ecosystem to know where to point you.

Sorry, I realize now this error goes the other way around. I'll try to get that package to update.
