ghcWorker :: [String] -> Ghc () -> IO (Worker Ghc)

Ghc worker. Pass options and initializer action

ghciWorker :: IO (Worker Ghc)

Interpreter worker is worker with preludeModules loaded

Initializers and actions

ghcRun :: [String] -> Ghc a -> Ghc a

Run ghc

withFlags :: Ghc a -> Ghc a

Alter DynFlags temporary

modifyFlags :: (DynFlags -> DynFlags) -> Ghc ()

addCmdOpts :: [String] -> Ghc ()

Add options without reinit session

setCmdOpts :: [String] -> Ghc ()

Set options after session reinit

importModules :: [String] -> Ghc ()

Import some modules

preludeModules :: [String]

evaluate :: String -> Ghc String

Evaluate expression

clearTargets :: Ghc ()

Clear loaded targets

makeTarget :: String -> Maybe String -> Ghc Target

Utils

listPackages :: Ghc [ModulePackage]

Get list of installed packages

spanRegion :: SrcSpan -> Region

Get region of SrcSpan

withCurrentDirectory :: FilePath -> Ghc a -> Ghc a

Set current directory and restore it after action

logToChan :: Chan (Note OutputMessage) -> DynFlags -> Severity -> SrcSpan -> PprStyle -> SDoc -> IO ()

Log ghc warnings and errors as to chan You may have to apply recalcTabs on result notes

logToNull :: DynFlags -> Severity -> SrcSpan -> PprStyle -> SDoc -> IO ()

Don't log ghc warnings and errors

data Ghc a :: * -> *

A minimal implementation of a GhcMonad. If you need a custom monad, e.g., to maintain additional state consider wrapping this monad or using GhcT.
