Can you explain why you need multiple GPRs and what are the issues you have?
@Fabien-Chouteau , what I mean by "gold standard" is a mature Alire-compatible project that you point to in the docs as "this is the way we expect complicated Alire-projects to be done."
For multiple GPRs, I'm just trying to split off a "testing gpr", it's probably simpler than what I think, the VS Code integration was just complaining about me having "multiple GPRs" and I'm a little confused about when I actually need an aggregate. Things are a lot easier for when I have working examples to follow to compare against documentation.
@mosteo , yes, targeted examples of especially GPR and Alire-specific things which are easier to understand with context. I was thinking maybe the example_ prefix would be protected from general use.
It'd also be a way to funnel people into the ecosystem if more comprehensive examples from learn.adacore.com were hosted on Alire.
Alejandro is working on a revamp of Alire
pins that will make things a lot cleaner and a lot easier.
About
testsing.gpr, this should not be in the root directory of your project. Tests (and everything that goes with) should be in a subdir. With the pin system you will be able to have a local crate for testing, and add specific dependencies for that testing crate (like aunit, or coverage analysis tool).
You should stay away from aggregate projects as much as possible, with Alire you should not have to use them.
Speaking of spark in Alire, is it possible there’ll be a “alr prove” option added in future? I was interested to try casually running gnatprove on my project but I realised I’d need to figure out what args to give it so it’d work like alr build does

but, you're right, it's not updating
it had autodisabled for lack of activity in the repo
I just enabled it again
thanks for the heads-up!
It was in Gemfile.lock that should not be checked-in.
Another Alire question: when I use a library from Alire, it gets fetched and obviously it has it's own GPR settings, like build mode etc. How would I propagate same settings for the libraries as well as my main project? I mean if I'd wish to do a release build? Does it happen automatically or do I just change them manually? 🤔
Oh noes, tried
alr publish command on windows, here are the results:C:\Users\hehar\dev\ada_cmd>alr -v publish

About your question about setting configuration, there's nothing standardized in gnat+gpr. You must make sure that you're setting whatever every library provides for self-config. For crates created with
alr init, they will have a crate_BUILD_MODE

NAME STATUS VERSION DESCRIPTION NOTES
sdlada X 2.5.4-1 Ada 2012 bindings to SDL 2
is my msys2 broken or what
I wish I had a proper linux box... have to fix the situation 😄
I had a bad hash on something last night, I can't remember what project it was
I'm fond of the recycled IT gear, with a bit of refurbishment (SSD drive etc). Too bad I picked a machine that has such power management that it's a bit of a mess in linux. I don't have the patience nor time anymore to hassle with those. 😒
I'll give it a try shortly
The problem is that
1.0 is broken this is hardcoded...
Nice, I saw 1.0.1 update, have to try it out. Otoh I started using virtualbox ubuntu more again. 😃
@mosteo: I rejected the Ada_cmd PR and created a new one for the Cmd_ada rename, it was such a hassle to change everything so I decided to create the PR from scratch as well 😄
But now I know that if naming things is the hardest CS problem, REnaming things must come as a close second one 😂
