Cabal often needs to do slightly different things on specific platforms. You
probably know about the os
however using that is very
inconvenient because it is a string and different Haskell implementations
do not agree on using the same strings for the same platforms! (In
particular see the controversy over "windows" vs "mingw32"). So to make it
more consistent and easy to use we have an OS
enumeration.

buildPlatform :: Platform Source #
The platform Cabal was compiled on. In most cases,
LocalBuildInfo.hostPlatform
should be used instead (the platform we're
targeting).
Internal
knownArches :: [Arch] Source #
Classification
data ClassificationStrictness Source #
How strict to be when classifying strings into the OS
and Arch
enums.
The reason we have multiple ways to do the classification is because there are two situations where we need to do it.
For parsing OS and arch names in .cabal files we really want everyone to be referring to the same or arch by the same name. Variety is not a virtue in this case. We don't mind about case though.
For the System.Info.os/arch different Haskell implementations use different names for the same or/arch. Also they tend to distinguish versions of an OS/arch which we just don't care about.
The Compat
classification allows us to recognise aliases that are already
in common use but it allows us to distinguish them from the canonical name
which enables us to warn about such deprecated aliases.
