plugin fails to load after tiddlywiki upgrade to 5.3

[ssow]

Hi,

It seems that there is an issue with tiddlymap plugins after upgrading to tiddlywiki 5.3. The following error is printed when starting nodejs

tiddlywiki[21557]: Error executing boot module $:/plugins/felixhayashi/vis/vis.js: "Global assignment is not allowed within modules on node."

Any clue regarding how to fix this issue ?

Thank you

Have you upgraded to the latest version of vis-network? That should fix the issue.

[ssow]

I'm unable to upgrade as the instance does not start :-)

[flibbles]

So this is happening in a standalone tiddlywiki file?

[ssow]

It's a nodejs installation.

[flibbles]

Right. You did say nodejs. My listening skills are poor.

If you're installing your plugins through the browser, you must have all your plugins in a "plugin" directory off your root dir? Is that correct?

[ssow]

yes. The plugins files are actually stored in the root directory and renamed (pathname included)

[flibbles]

All right, I think I figured this out.

1. Download the vis-network json file from here.
2. On the command line, cd to the root directory of your project, and then type:
   • tiddlywiki --import <path/to/that/file.json> application/json ...where <path/to/that/file.json> is probably something like ~/Downloads/vis-network.json

That should sort you out. Sorry you have to go through this. Tiddlywiki V5.3.0 has suddenly decided to disallow Global assignment in nodejs, which is something that the vis-network relied on. The new version has a workaround for this.

Edit: corrected application/son to be application/json

[flibbles]

Crap. That's not going to work, is it? The command line won't even run because of this issue.

Let me think about this.

[ssow]

It does not work as the program stopped during loading :-) I need to remove the plugins manually, i guess.

[flibbles]

Okay, I think I figured it out.

1. Yes, remove the old vis-network plugin manually like you said.
2. You can put that vis-network.json file directly into your <root>/tiddlers directory. That appears to make it load as a plugin, and while it's not a perfect place for it, this will at least allow you to load up your tiddlywiki.

[flibbles]

But you should only need to remove the vis-network plugin, which should be in your <root>/plugins directory, I think, depending on how you installed.

[ssow]

I've removed all \$__pluginsfelixhayashi* files and the instance is online. I guess it would be wise to add a "safe mode" flag to tiddlywiki nodejs which disables plugins loading :-)

Thank you very much for your help.

Sincerely

[flibbles]

Sorry you had to fully uninstall TiddlyMap to get back online. If you upgrade to the latest versions of TMap and its dependencies, everything should be functional again.

Edit: Which, by the way, can be found here

[ssow]

No worries. I've learnt something from the experience.
