alibuild recipe (reference) : requirements

[maireiphc]

Adding extra details about the logic I understood for the fields :

• requires,
• build_requires,
• runtime_requires

This comes after some mail exchanges with Adrian Sevcenco, Giulio Eulisse + some local tests on one alidist recipe (lhapdf.sh). To be revised by Giulio to make sure that this is correct.

Thank you for this. We should probably check the the runtime_requires behave correctly. I do no think we ever used them...

I confess that I discovered the runtime_requires feature by re-reading your text a few hours ago (in the env variables). I extrapolated the text, I did not test the thing. I have been so far unaware of such a thing to exist. I indeed never stumbled upon runtime_requires in any recipe. At the moment, there is no occurrence of it among our alidist recipes.
