Error in "Generate Single-page HTML Export" after upgrade to jArchi 1.6.1

[Xiaoqi]

Hello,

I use the "Generate Single-page HTML Export" quite a lot, after upgrading to jArchi 1.6.1, I start to see below error which looks like the "_" is not recognized:

Code Select Expand

org.graalvm.polyglot.PolyglotException: ReferenceError: "_" is not defined
at <js>.:program(Generate Single-page HTML Export.ajs:44)
at <js>.:program(<eval>:1)
at org.graalvm.polyglot.Context.eval(Context.java:399)
at com.oracle.truffle.js.scriptengine.GraalJSScriptEngine.eval(GraalJSScriptEngine.java:478)
at com.oracle.truffle.js.scriptengine.GraalJSScriptEngine.eval(GraalJSScriptEngine.java:446)

In the source, the line 44 shows this usage:

Code Select Expand

// Use Mustache.js-style templating
_.templateSettings = {                      --> this is line 44
  interpolate: /\{\{(.+?)\}\}/g
};

And the GitHub site for the plug-in script is still the old one, do you have any advise what I can change to make it working again? Or downgrade jArchi?

Thanks,
Xiaoqi

Added: I tried to downgrade to jArchi 1.6.0, it's the same error message.
Further downgrade back to jArchi 1.5.0, now the Export to Single HTML Page is working again.

So suspect something different from 1.5.0 to later version. FYI...

Hi, there's a preference in Archi, under "Scripting" tab to "Enable Common JS Support". You can turn that off to get it working for now.

The script needs changing those instances of __DIR__ loading. See https://github.com/archimatetool/archi-scripting-plugin/wiki/Using-Node.js-modules

@Jean-Baptiste Sarrodie What do you advise?

[Phil Beauvoir]

I think you need to replace those load statements with these:

const _ = require(__DIR__ + "libs/underscore-min.js");
const readFully = require(__DIR__ + "libs/marked.min.js");
const marked = require(__DIR__ + "libs/marked.min.js");

Thanks Phil for your quick reply, yes, that's the one, I upgraded to 1.6.1 again and as you mentioned, uncheck that "Enable Common JS Support" and the script can generate one-page HTML now.

So, it would need to wait JB to update this script then I can check this option I think. For now, I can continue work.

Thanks!

You could edit your copy of the script if you want.

Thanks Phil again.

I've tested and it's working now with following changes in the definition part:

Code Select Expand

// 2024/02/08: Comment below after jArchi 1.6.1 and give cost definition
load(__DIR__ + 'libs/nashorn-polyfills.js');
// load(__DIR__ + 'libs/underscore-min.js');
// load(__DIR__ + 'libs/marked.min.js');
const _ = require(__DIR__ + 'libs/underscore-min.js');
const marked = require(__DIR__ + 'libs/marked.min.js');

I only change the "underscore-min.js" and "marked.min.js", then re-check the "Enable CommonJS Support", it's enough for generating the HTML. So I leave the first Load without change yet.

Regards,
Xiaoqi
