max twiddlers in a wiki?

[John Meyer]

Is there a practical limit to the number of Twiddlers in a TiddlyWiki?

I imported over 1000 bookmarks into TiddlyWiki from Evernote, and I'm still under 4MB (only about 40 or so have notes, the rest are just title & link)... anyway, it's become very fragile... for example I tried to change the default Twiddler & got the JavaScript error (parsing JSON, per Chrome dev tools) & had to fall back to a backup.  So I tried adding a Table of Contents, saved 2 tiddlers, hit F5, error... restore the backup again

seems strange for a tool that's been around so long, I'm thinking it must be something I'm doing, but damned if I can figure out what?

P.S. I'm a dev (.NET, mostly web), so don't worry about being too technical

Thanks!

Should absolutely not be a problem. I think successful tests have been made with 80.000 tiddlers and 4MB is pretty small.

That's a basic thing to do so exactly what did you do?

Again, you're not really describing what you're doing but adding a ToC should not cause any problems at all. 

 

You can put up a public wiki test case via e.g http://tiddlywiki5.tiddlyspot.com/

So in an effort to get more information, I tried the following... opened the last known good version of my TW in Chrome (PC is less than a week old, so definitely a current version of Chrome)... I clicked edit on the GettingStarted tiddler, then save on that tiddler, then save on the wiki... the resulting file won't open & is 9kb smaller (went from 3.86MB to 3.85MB... in theory the should be identical)

diffing the files shows that all the &amp; got unescaped to just &, including all the tiddler titles inside the "This <a class="tc-tiddlylink-external" href="https://tiddlywiki.com" rel="noopener noreferrer" target="_blank">TiddlyWiki</a> contains the following tiddlers:" tiddler as well as a bunch of JS files embedded in a JSON object (which explains the JSON parse error... but not why the change happened)

example:

good:

        &quot;$:/language/ControlPanel/Basics/DefaultTiddlers/BottomHint&quot;: {

            &quot;title&quot;: &quot;$:/language/ControlPanel/Basics/DefaultTiddlers/BottomHint&quot;,

            &quot;text&quot;: &quot;Use &amp;#91;&amp;#91;double square brackets&amp;#93;&amp;#93; for titles with spaces. Or you can choose to &lt;$button set=\&quot;$:/DefaultTiddlers\&quot; setTo=\&quot;[list[$:/StoryList]]\&quot;&gt;retain story ordering&lt;/$button&gt;&quot;

        },

bad:

        &quot;$:/language/ControlPanel/Basics/DefaultTiddlers/BottomHint&quot;: {

            &quot;title&quot;: &quot;$:/language/ControlPanel/Basics/DefaultTiddlers/BottomHint&quot;,

            &quot;text&quot;: &quot;Use &#91;&#91;double square brackets&#93;&#93; for titles with spaces. Or you can choose to &lt;$button set=\&quot;$:/DefaultTiddlers\&quot; setTo=\&quot;[list[$:/StoryList]]\&quot;&gt;retain story ordering&lt;/$button&gt;&quot;

        },

How did you import from Evernote?

[John Meyer]

used the Evernote import plugin, then uninstalled that plugin when I was done... I think I'm going to try doing an upgrade from my last known good into a new wiki, to see if that makes a difference... maybe something got corrupted on import... it does make kind of a mess of the tiddlers it creates

[Mark S.]

My guess is that some of the titles or fields created have illegal characters or characters that TW doesn't know how to handle. It might even be just one bad title.

[John Meyer]

Don't know, but "upgrading" it seems to have done the trick

been looking for a way out of Evernote's annoying bugs & pricey subscription without losing the convenience/syncing/etc... TiddlyDesktop & TW5 in the Sky seem like problem solved :)
