fromDefaults :: GenericPackageDescription -> CondVars Source #

Create a CondVars from the default flags of the cabal package description. The os, arch and compilerFlavor fields are initialized by the ones the cabal library was build on.

enableFlag :: FlagName -> CondVars -> CondVars Source #

Enable the given flag in CondVars.

disableFlag :: FlagName -> CondVars -> CondVars Source #

Disable the given flag in CondVars.

eval :: CondVars -> Condition ConfVar -> Bool Source #

Evaluate the Condition using the CondVars.
