customFieldsPD

[snoyberg]

I have a use case where I'd like to use customFieldsPD. However, the documentation for that field makes it clear that the field has some deeply magical stuff going on, and shouldn't be trusted. My question is: is there any use case under which it's safe to use that field? For example, is there a guarantee that if I use parsePackageDescription and then use customFieldsPD on those results that I'll get the fields I'm looking for?

We are talking about:

cabal/Cabal-syntax/src/Distribution/Types/PackageDescription.hs

Lines 125 to 127 in 0abbe37

	customFieldsPD :: [(String,String)], -- ^Custom fields starting
	-- with x-, stored in a
	-- simple assoc-list.

I've not found nothing in docs about custom fields so i am not sure if the warning is there anymore.
However iirc there are some actual usages and the question were not answered so i guess we can close this, feel free to reopen on toher case
