Distribution.Compiler
Description
This has an enumeration of the various compilers that Cabal knows about. It also specifies the default compiler. Sadly you'll often see code that does case analysis on this compiler flavour enumeration like:
case compilerFlavor comp of GHC -> GHC.getInstalledPackages verbosity packageDb progdb
Obviously it would be better to use the proper Compiler abstraction
because that would keep all the compiler-specific code together.
Unfortunately we cannot make this change yet without breaking the
UserHooks api, which would break all custom Setup.hs files, so for the
moment we just have to live with this deficiency. If you're interested, see
ticket #57.

defaultCompilerFlavor :: Maybe CompilerFlavor Source #
The default compiler flavour to pick when compiling stuff. This defaults to the compiler used to build the Cabal lib.
However if it's not a recognised compiler then it's Nothing and the user
will have to specify which compiler they want.
Per compiler flavor
data PerCompilerFlavor v Source #
PerCompilerFlavor carries only info per GHC and GHCJS
Cabal parses only ghc-options and ghcjs-options, others are omitted.
