Looks like maybe this one is done? I'm not sure where the packages were supposedly used, but I don't see them in composer.json.

Can offer a random confirmation.

I can if not here, I can only assume it got fixed upstream...
Regardless, it's not pinned to crazy broken library and works on current php (7.4.6)

Actually I misunderstood the OP. They mentioned 3 packages by name and claimed they were abandoned. I looked for them in php-gui's composer.json and didn't see them. That is all I was observing. I didn't realize this was something composer was reporting. I thought I had a memory of eventually noticing similar but different messages from composer about packages while installing, but now I can't reproduce it, at least not by removing and then adding it again. Perhaps I was thinking of a different tool I tried...

Anyway, php-gui may not be dependent on abandoned packages, but the v0.4.3 of react/child-process that it installs is very out of date, and I suspect it is partially broken for the purposes of this project. According to their README and their release notes, "limited Windows support" was not added until v0.6.0. I suspect this is connected to a problem I have been having where, after adding a decent number of components to a window, if I keep starting and stopping the program while developing, it sometimes does not close down all the way, and has to be force closed. Then once you start it again, the UI is all messed up, so you have to close the window, force close the messaging (with Ctrl+C at the terminal), and then if you start it again, the UI usually goes back to normal.

Also, every time the window gets closed (my project only has one main window) there is an error that occurs. The error message:

proc_terminate() expects parameter 1 to be resource, null given

Here is a print_r() of the entire exception (after I have converted the error into an ErrorException) :

RECURSION

The dump keeps going on after that for thousands of lines. I suspect this is all because of using a version of react/child-process that is not really supposed to be compatible with Windows. You can see their README and release notes for more information about how to use the newer version in a Windows compatible way. It is not as simple as just updating to the new version or else I would have made a PR. If you just update to the new version, it throws a LogicException, as you are supposed to use it in a specific way on Windows to get limited Windows support.

I'm on:
Windows 10 Home 64 bit. Version 1909. OS build 18363.836
php 7.4.6

UPDATE: The error occuring upon closing the program still happens every time for me, but the other one where the lazarus messaging remains running in the terminal until force closing is very hard to reproduce now.
