Download a Tiddler Using Python/Bash

[j3d1H]

Maybe a little off-topic, sorry. I want to use Python and/or Bash to copy a single tiddler from the TiddlyWiki file to a different file. Any clues on how to do this?

I would attempt to parse the file for the correct tiddler, but I would prefer not to do that, if there's a simpler way. It seems like it would be hard to do. I need to do this in a script, so I can't click "export tiddler".

Any help is appreciated!

You may be able to do it using node, there is a script called ginsu in the repo that splits a wiki into tiddlers but I am not sure how to convert it to use python or bash.

Well, the ginsu script would already be bash, or something similar. You need the node executable to run the script but you can call it from python or bash and then process the output.

Jed: I would really rather not use node, it hasn't worked very well for me in the past. Any other possible solution?

[Jed Carty]

I haven't found any good server-side html parsing solutions. The node scripts are the only thing I have found that is at all reliable for pulling out tiddlers.

I don't think there's really anything else someone's made.  You can try to do HTML munging using BeautifulSoup in python.  Should be able to use something like:

with open("NameOfFile.html") as f:
 soup = BeautifulSoup(f.read(), "html.parser")


soup.find_all('div', attrs={'title': 'NameOfTiddler'})

That'll get the the Div that represents the tiddler, but you'll have to figure out how to parse it.  And it relies on BeautifulSoup4, which you can get with 

pip install beautifulsoup4

If you end up writing something from scratch, you might want to refer to the fairly simple code that TW5 uses to extract the tiddlers from TWC/TW5 HTML files:

Matthew Lauber: Sorry for getting back to you so late, but this works perfectly for what I need! Thank you.

[Matthew Lauber]

Glad to help.  If you do end up figuring out how to parse tiddlywiki wikitext in python/bash, please post about it to the group.
