TTCN-3 syntax highlighting in gerrit [message #1838001]

As not only Osmocom but also Eclipse TITAN itself is using gerrit for code review, I think you also might be interested in having TTCN-3 syntax highlighting in gerrit.

gerrit itself uses highlight.js to perform syntax highlighting of many other programming languages, but unfortuantely not for TTCN-3.

I've created a related feature request at https://github.com/highlightjs/highlight.js/issues/2999 and would even be willing to contribute financially to it, in case somebody wants to work on it.

Just thought I'd share this here, in case somebody might already be working on this, to avoid any duplication of work. I woldn't be surprised if this has come up before within Eclipse TITAN developers.

Regards,
Harald

Hi Harald,

This is a nice initiative, thank you for raising the idea.

Some time ago, Yann Garcia - as expert from STF 569 - contributed a TTCN lexer to the Rouge ruby package that is used in Gitlab to highlight syntax. You may see the PR on the project, hopefully it may help (I am not allowed to post links, but you may find it by visiting Github, project rouge-ruby/rouge, Pull request 1337)

Also, there are some IDE support packages available at the Tools > Plugins and Extensions page on the official TTCN-3 org website (again, I can't post the direct link) , maybe they could serve as starting point.

Thanks for your feedback, Michele.

There's also a vim syntax highlighting module for TTCN-3 (which I'm using every day) available from https://github.com/gustafj/vim-ttcn - but unfortuantely neither of that (nor ruby code, ...) is going to help much with adding highlighting support ot that javascript library, I'm afraid.

Our internal gerrit server has syntax highlight for TTCN and ASN files. I\m trying to find some information about it.

Until now i found only an old mail mentioning "codemirror extension logic(mode) for TTCN3, ASN.1 and .cfg files."

Ah, thanks for mentioning this. Based on my research it would mean that highlight.js would have had to be extended - or some completely other mechanism for syntax highlighting introduced into the gerrit codebase.

In eiter case, it would be great to share with the general public, possibly even contributing it upstream.

The latter would mean that https://gerrit.eclipse.org, https://review.gerrithub.io/(both used by TITAN for many repositories) and also our https://gerrit.osmocom.org/ could benefit from this.

It seems our gerrit uses codemirror to display the code in the review plane. There is a plugin for it.
The https://codemirror.net/ supports the TTCN and the cfg syntax of the TITAN out of the box.

We're using gerrit 3.2.3 with the corresponding gerrit-codemirror plugin v3.2.3.

However, gerrit.osmocom.org does not provide any syntax highlighting: of ttcn3 code:, as you can see at https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/22802

Likweise. https://gerrit.eclipse.org/ (on gerrit 3.2.6) doesn't provide tTCN syntax highlighting either.

So I don't think that the official/public gerrit-codemirror plugin supports ttcn syntax highlighting. I would suspect you use some patches? Would it be possible to publish those, possibly even submit them upstream?

I think https://gerrit.googlesource.com/plugins/codemirror-editor/+/refs/heads/master/gr-editor/codemirror-element.html lists the languages supported by the gerrit plugin., and ttcn[3] is not part of it.

Without understanding anything about javascript or web frontend development, I've tried my humble attempt to make this work and submitted a patch in https://gerrit-review.googlesource.com/c/plugins/codemirror-editor/+/296842 - unfortuantely I'm not able to test this myself as I cannot get the build instructions for the codemirror-editor gerrit pluging to work.

So I'm not sure if that patch will go anywhere. It would still be good to understnad how the internal gerrit Gabor refers-to has adressed the question of TTCN support.

Honestly, I don't know how the codemirror plugin is integrated into the our gerrit.
Our unit just use it and supported by the central IT unit.

Maybe the mime type settings are missing, but I don't know

Our gerrit kept the old GUI. The syntax highlight works with the old UI but not with the new UI.

Thanks for following up. That must be a rather old version (2.x). Since 3.0, the "old" UI is still provided in any supported/stable versions of gerrit. We had to upgrade some time ago due to that in. The latest 2.x branch (2.16) is EOL, see https://www.gerritcodereview.com/releases-readme.html

Is highlight.js the only syntax highlighter available in gerrit or is there maybe an option to use another one, say pygments, for example?

i believe the syntax highlighting happens in the client/browser, that's why highlight.js is used.

For the same reason, I don't think you can easily adapt it to use any other tool in any other language.
