Extension talk:Highlightjs Integration/Flow

While the installation instructions are correct, there is a major issue (at least at time of writing) one needs to be aware of or else enabling this extension will make your Wiki unreachable.

The folder inside the download is called Highlightjs_Integration-master instead of just Highlightjs_Integration. This long name will be truncated by many file managers, so the difference isn't always obvious. Just copying the folder from the download to your extensions folder, will make your wiki generate a HTTP 500 error.

Rename the folder to Highlightjs_Integration before enabling the extension, and everything should be fine.

Thanks, this caught me out too! Most other extensions unzip to the correct folder name. Is it possible to make that the case for this extension too? @NikusPokus

Would like to see line numbers added like is available with the SyntaxHighlight Extension. Nicole Sharp (talk) 11:53, 27 March 2021 (UTC)

This is apparently "not an oversight but a feature:" https://highlightjs.readthedocs.io/en/latest/line-numbers.html. Nicole Sharp (talk) 14:52, 27 March 2021 (UTC)

There is an extension that uses Prism.js and it supports line numbers. I am not allowed to add the link here, but search for SyntaxHighlight_PrismJS on GitHub

Did ya get that to work, seems to not work on latest 1.4.2

sadly it is dead

Is there any way to highlight lua code with this extension? All other languages are working.

Hello,

I try to change tab-size how I can do that?

I try to change in some css with add tab-size : 4 in the part .hljs but don't work.

thank you.

Hello,

I try to get it for the vb language, so I try to follow this part so I get vb.net and I replace highlight old folders and change the extension.json thing (like in the this).

I use a black theme so it's easy to know when it's working...

But he didn’t work if I just put <syntaxhighlight lang=""> I don't have any colour (but I have my black theme), so maybe I miss something because for C# it works with the lang specific and without.

Maybe because I get itowd from Getting highlight.js (highlightjs.org) in version 11.4.

Any help is appreciated.

Hello, Does it work if you specify the language? If yes, it seems to be the detection of the language which can't find out which language it is from the code you want to highlight. So test with a bigger code to highlight. If it still doesn't work, there is a problem with the language detection and you have force it. Other question: was it working without upgrading highlight.js?

Thank you and sorry for your time, I resolved it.

So the detection of language worked but not for vb.

To resolve this I simply follow carefully this part and then it worked.

I can't remember my error so thank you again for taking your time !

Here in this wiki the SyntaxHighlight extension is at work. Usually one uses the <syntaxhighlight> tag to mark those parts which shall be highlighted. Pages like MediaWiki:Gadget-site.css are highlighted. But there I find no <syntaxhighlight> tag in the wiki code. Will this extension hightlight such css pages without the tag as well?

No. This extension only affects code contained within HTML/XML elements (tags) such as syntaxhighlight. To highlight without tags requires changing the content model of the page, such as with the SyntaxHighlightPages Extension. You can use both SyntaxHighlightPages and Highlightjs_Integration at the same time, but they use different highlighting libraries and styles (Pygments vs. HighlightJS).

I would really like to see the HighlightJS library and style options applied to page content models though like with SyntaxHighlightPages. Nicole Sharp (talk) 14:08, 27 March 2021 (UTC)

When I try to edit a page using VisualEditor, not is shown in the code lines. Is there a way to make it work in VisualEditor like SyntaxHighlight_GeSHi does?

I'm using version 1.2 in xampp with MediaWiki 1.31.1, PHP 7.0.33.

I also cannot preview the syntax highlighting using HighlightJS Integration 1.1 for MediaWiki 1.35.1 LTS (with PHP 7.4.15). A small inconvenience though for the additional language support compared to using Pygments SyntaxHighlight. Nicole Sharp (talk) 14:02, 27 March 2021 (UTC)

Where did you get version 1.2? The most recent version available on GitHub is 1.1. Nicole Sharp (talk) 14:04, 27 March 2021 (UTC)

I installed this extension (v1.2). I'm running MediaWiki v1.32 on a shared linux computer (SiteGround), PHP 7.0.33. The code highlighting works, but the background is black instead of light gray.

I fixed it by changing the style to vs.css in extension.json. I assumed the default look would be similar to what is shown in the description.

Yes, using default.min.css (for HighlightJS 10) fits in better with the MediaWiki Vector default style, but the dark background from railcasts.min.css is admittedly a bit easier to read. Haven't decided on a favorite HighlightJS style yet but you can browse through the style options on the HighlightJS demo site. Nicole Sharp (talk) 13:58, 27 March 2021 (UTC)

I can't get maxima recognized for syntax highlighting. Any suggestions? I already upgraded to HighlightJS 10.7.1, though Maxima has been available for HighlightJS since 9.2.0. Maxima highlighting is not available at all with Pygments SyntaxHighlight so would really like to see this working if possible. Nicole Sharp (talk) 11:27, 27 March 2021 (UTC)

I got it working. Add "highlight/languages/maxima.min.js", to extension.json as below.

            "scripts": [
                "highlight/highlight.min.js",
                "highlight/languages/maxima.min.js",
                "init.js"
            ],

It would be good if there was a way to load HighlightJS from a CDN hyperlink instead of needing a local copy installed. SimpleMathJax has this ability. Nicole Sharp (talk) 09:56, 27 March 2021 (UTC)
