Obsidian to org-roam migration kit – a completely half-baked attempt at moving from Obsidian to org-roam which nevertheless works (for me).

No, no! Good job I'd say, Python is meant for such hackery.
Hey @s-c-p, thanks for the comment. That is really kind of you. Hope it has helped you, though I have found a few bugs which I manually corrected over my transition to org-roam.
Hi @rberaldo! I took this code and ran with it to make https://github.com/jml/obsidian-to-org, which I've used to convert my Obsidian files to org-roam. I hope you don't mind.
Let me know if you have an opinion about license. I'll default to GPL 3 if I don't hear from you.
@jml really cool work! GPL 3 is good to me. Maybe I'll update this gist to set a license and link to your work.
Thanks :) I've updated the repo with the license.

This is absolutely half-assed – I'm a linguist, not a programmer – but it still seems to have worked to migrate my largish collection of notes from Obsidian to org-roam.
Feel free to criticize the hell out of it.
I start by converting all my beginning-of-line non-markdown-standard comments – lines starting and ending by
%%– to transitional comments which are later translated into properorgformat comments.I ensure there's
\nbetween instances of---and text sopandocdoesn't go all crazy making new headers.Then
pandocdoes its thing.After converting the comments into their final form, some arcane index alchemy I concocted converts wiki-style links into
org-style links.This took me more than I'd like to admit to put together, so I hope someone gets good use out of it and contributes a better version.
Have fun! All hail Eris!
