TW5: splitting a TW file based on tags

[HowardM]

I have a large file which is very slow to save individual tiddler edits on my iPad - I gather this is a recognised issue with the current version of the app which will be addressed in a future version of it.  In the meantime, I would like to split the file based on tags, but cannot find a way of doing so without individually dragging and dropping a very large number of tiddlers.  Has anyone found a simple way of doing this ?

I have previously applied a method using the Chrome Javascript console to delete tiddlers defined in a filter - I cannot remember who posted this advice - but this does not seem to work on TW5.1.2 - I just get 'invalid - unexpected token' messages.

Grateful for any help.

Hi Howard

Here's a JavaScript snippet to delete all tiddlers matching a filter. It uses the filter string currently loaded in the advanced search tiddler so you can preview which tiddlers will be deleted:

var tiddlers=$tw.wiki.filterTiddlers($tw.wiki.getTiddlerText("$:/temp/advancedsearch"));for(var t=0;t<tiddlers.length;t++) {console.log("Deleting " + tiddlers[t]);$tw.wiki.deleteTiddler(tiddlers[t])};console.log(tiddlers.length + " tiddlers deleted");

Best wishes

Jeremy

Hi Jeremy

That was great - your snippet allowed me to split my large file into seven separate files in 20 minutes.

Thanks for your help

Hi, this is exactly what I want to do.
Could you please give some instructions of where to put the snippet and how to execute it?

Thanks
Jon

Open your browser's debugger console (ctrl-shift-J in Chrome).  Typically, to invoke javascript code from the console, you just type (or paste) the code into the input area, and press enter to execute.   The snippet of code that Jeremy provided should be copied/pasted as a single line of text.  That should do it.

enjoy,
