i love tiddlywiki as a single file application for years, but now i had the task to migrate the content to a web based wiki. there are a lot of guides old and new, but nothing really worked for me. my task was to export each tiddler into a .txt file (can be changed to .md as well, but you have to tweak the content yourself to the official markdown language)
There are few similar tools, albeit some of them are years old. I researched the ecosystem of Python tools for TiddlyWiki a couple of months ago and this is what I managed to comb into my bookmarks:
Did you write your tool to solve a problem with a strictly defined final requirement, or are you planning to extend it in the future, like adding support for importing tiddlers into a single file wiki, adding support for import/export operations on encrypted single file wikis etc?
