Environment values of spawned process

[pjljvandelaar]

When an alire project spawns a process, does that process get the same environment values as the original process / alire project?

I am asking since Non_Blocking_Spawn of GNAT.EXPECT (g-expect.adb) called by gnatcoll-projects.adb crashes on windows on the command gnatls.exe -v
while

> alr printenv --powershell | Invoke-Expression
> gnatls.exe -v

succeeds.

Alire sets the environment that you can see with alr printenv for its spawned build processes, and for alr exec. We are using the functions in GNAT.OS_Lib though.

For other processes unrelated to Ada like git, they will see the same environment as alr itself.

So the process spawning gnatls from inside my program (started with alr run) will have the environment as shown with alr printenv?

We have a little inconsistency here now that I've inspected the code but yes, as long as you don't use alr run --skip-build, the environment will have been set during the build for any subsequent spawn.
