Now it's working!

This is the console log I got when running in Firefox:

Navigated to http://phorge.blackbird.turdus.local/diagram/

I'm on branch arcpatch-D25577 now but I still have an empty screen.

I might be doing something wrong.
When I open Diagrams, I see an empty screen with only the application's title "Diagram" and its corresponding icon on top

The reason why I did not put all the draw.io js and css files in the repo is because

1. draw.io is a very large repo

and 2) the draw.io people commit a lot (as in more than once a week).

Sorry for the late reply.
The Diagrams extension (which just references the draw.io codebase) already has something like that in it.
You can use {DIAG1} in remarkup for showing Diagram 1 in e.g. a wiki document.
You can also import Mermaid diagrams in here.

Mission accomplished.
Thanks

I thought this was already in the repo, but I forgot to execute arc land... (sorry)
I bump into a 403 error when I execute it now.
I had one merge conflict in resources/celerity/map.php which I corrected manually.

I copy/pasted the keys of the getStyleMap() function dictionary into chatgpt with some remark that they were part of a syntax highlighting mechanism.
I asked it to translate them into something more readable.

Can someone explain what these "Code coverage needs to be enabled in php.ini by setting 'xdebug.mode' to 'coverage'" messages mean ?
Are these automated unit tests run on we.phorge.it or on my system ?

I'm not sure if I understand your question.
I thought the fix was already implemented by aklapper?
What do you want me to do?

The change in src/applications/people/mail/PhabricatorPeopleEmailLoginMailEngine.php also seems to be solved somehow.
I tried to simulate the issue with bin/mail send-test --to mturdus --subject "" and pressing CTRL-D.
I received an empty email (containing no subject and no body).

I'm ready to publish a first version, but I don't understand how to publish it under Phactory?
Do I need to publish on Github first ?

Thanks.
Yes, it will be open source

I got a bit further and got a new issue :-)

Yes, this was indeed the answer I was afraid of...

Mistery resolved! Git was right. The patch was not successfully land-able since the kind user @aklapper already landed a fix for this 3 days ago

rP1c098c273d06: Fix PHP 8.1 "strlen(null)" exception calling Conduit's user.whoami

Ouch :D

Thank you very much anyway @mturdus - For consolation, you unlocked this command:

arc anoid

I uncommented a line in the editor executed by arc diff and it seemed to work

Updating D25267: Fix PHP 8.2 "trim(null)" exception which causes Conduit's user.whoami to fail

I'm sorry I didn't know I had to more.

This sounds indeed logical that it's only for POST calls.
I'll look into it further this week
