Description

Dynamic flags

Most flags are dynamic flags, which means they can change from compilation to compilation using `OPTIONS_GHC` pragmas, and in a multi-session GHC each session can be using different dynamic flags. Dynamic flags can also be set at the prompt in GHCi.

warningGroups :: [(String, [WarningFlag])] #

Warning groups.

As all warnings are in the Weverything set, it is ignored when displaying to the user which group a warning is in.

warningHierarchies :: [[String]] #

Warning group hierarchies, where there is an explicit inclusion relation.

Each inner list is a hierarchy of warning groups, ordered from smallest to largest, where each group is a superset of the one before it.

Separating this from `warningGroups` allows for multiple hierarchies with no inherent relation to be defined.

The special-case Weverything group is not included.

data HscTarget #

The target code type of the compilation (if any).

Whenever you change the target, also make sure to set `ghcLink` to something sensible.

`HscNothing` can be used to avoid generating any output, however, note that:

- If a program uses Template Haskell the typechecker may need to run code from an imported module. To facilitate this, code generation is enabled for modules imported by modules that use template haskell. See Note [-fno-code mode].

Constructors

HscC | Generate C code.
HscAsm | Generate assembly using the native code generator.
HscLlvm | Generate assembly using the llvm code generator.
HscInterpreted | Generate bytecode. (Requires `LinkInMemory`)
HscNothing | Don't generate any code. See notes above.

isObjectTarget :: HscTarget -> Bool #

Will this target result in an object file on the disk?

defaultObjectTarget :: Platform -> HscTarget #

The `HscTarget` value corresponding to the default way to create object files on the current platform.

targetRetainsAllBindings :: HscTarget -> Bool #

Does this target retain *all* top-level bindings for a module, rather than just the exported bindings, in the TypeEnv and compiled code (if any)? In interpreted mode we do this, so that GHCi can call functions inside a module. In HscNothing mode we also do it, so that Haddock can get access to the GlobalRdrEnv for a module after typechecking it.

data GhcMode #

The `GhcMode` tells us whether we're doing multi-module compilation (controlled via the GHC API) or one-shot (single-module) compilation. This makes a difference primarily to the Finder: in one-shot mode we look for interface files for imported modules, but in multi-module mode we look for source files in order to check whether they need to be recompiled.

data ModRenaming #

Represents the renaming that may be associated with an exposed package, e.g. the `rns` part of `-package "foo (rns)"`.

Here are some example parsings of the package flags (where a string literal is punned to be a `ModuleName`:

- `-package foo` is `ModRenaming True []`
- `-package foo ()` is `ModRenaming False []`
- `-package foo (A)` is `ModRenaming False [(A, A)]`
- `-package foo (A as B)` is `ModRenaming False [(A, B)]`
- `-package foo with (A as B)` is `ModRenaming True [(A, B)]`

data Option #

When invoking external tools as part of the compilation pipeline, we pass these a sequence of options on the command-line. Rather than just using a list of Strings, we use a type that allows us to distinguish between filepaths and 'other stuff'. The reason for this is that this type gives us a handle on transforming filenames, and filenames only, to whatever format they're expected to be on a particular platform.

## Manipulating DynFlags

addPluginModuleName :: String -> DynFlags -> DynFlags #

defaultDynFlags :: Settings -> LlvmTargets -> DynFlags #

The normal `DynFlags`. Note that they are not suitable for use in this form and must be fully initialized by `runGhc` first.

defaultWays :: Settings -> [Way] #

interpWays :: [Way] #

interpreterProfiled :: DynFlags -> Bool #

interpreterDynamic :: DynFlags -> Bool #

initDynFlags :: DynFlags -> IO DynFlags #

Used by `runGhc` to partially initialize a new `DynFlags` value

defaultFatalMessager :: FatalMessager #

defaultLogAction :: LogAction #

defaultLogActionHPrintDoc :: DynFlags -> Handle -> SDoc -> PprStyle -> IO () #

Like `defaultLogActionHPutStrDoc` but appends an extra newline.

defaultLogActionHPutStrDoc :: DynFlags -> Handle -> SDoc -> PprStyle -> IO () #

defaultFlushOut :: FlushOut #

defaultFlushErr :: FlushErr #

getOpts #

Arguments

:: DynFlags | `DynFlags` to retrieve the options from
-> (DynFlags -> [a]) | Relevant record accessor: one of the `opt_*` accessors
-> [a] | Correctly ordered extracted options

Retrieve the options corresponding to a particular `opt_*` field in the correct order

getVerbFlags :: DynFlags -> [String] #

Gets the verbosity flag for the current verbosity level. This is fed to other tools, so GHC-specific verbosity flags like `-ddump-most` are not included

updOptLevel :: Int -> DynFlags -> DynFlags #

Sets the `DynFlags` to be appropriate to the optimisation level

setTmpDir :: FilePath -> DynFlags -> DynFlags #

setUnitId :: String -> DynFlags -> DynFlags #

interpretPackageEnv :: DynFlags -> IO DynFlags #

Find the package environment (if one exists)

We interpret the package environment as a set of package flags; to be specific, if we find a package environment file like

    clear-package-db
    global-package-db
    package-db blah/package.conf.d
    package-id id1
    package-id id2

we interpret this as

    [ -hide-all-packages
    , -clear-package-db
    , -global-package-db
    , -package-db blah/package.conf.d
    , -package-id id1
    , -package-id id2
    ]

There's also an older syntax alias for package-id, which is just an unadorned package id

    id1
    id2

canonicalizeHomeModule :: DynFlags -> ModuleName -> Module #

Given a `ModuleName` of a signature in the home library, find out how it is instantiated. E.g., the canonical form of A in `p[A=q[]:A]` is `q[]:A`.

## Parsing DynFlags

parseDynamicFlagsCmdLine #

Arguments

:: MonadIO m |
=> DynFlags |
-> [Located String] |
-> m (DynFlags, [Located String], [Warn]) | Updated `DynFlags`, left-over arguments, and list of warnings.

Parse dynamic flags from a list of command line arguments. Returns the the parsed `DynFlags`, the left-over arguments, and a list of warnings. Throws a `UsageError` if errors occurred during parsing (such as unknown flags or missing arguments).

parseDynamicFilePragma #

Arguments

:: MonadIO m |
=> DynFlags |
-> [Located String] |
-> m (DynFlags, [Located String], [Warn]) | Updated `DynFlags`, left-over arguments, and list of warnings.

Like `parseDynamicFlagsCmdLine` but does not allow the package flags (-package, -hide-package, -ignore-package, -hide-all-packages, -package-db). Used to parse flags set in a modules pragma.

parseDynamicFlagsFull #

Arguments

:: MonadIO m |
=> [Flag (CmdLineP DynFlags)] | valid flags to match against
-> Bool | are the arguments from the command line?
-> DynFlags | current dynamic flags
-> [Located String] | arguments to parse
-> m (DynFlags, [Located String], [Warn]) |

Parses the dynamically set flags for GHC. This is the most general form of the dynamic flag parser that the other methods simply wrap. It allows saying which flags are valid flags and indicating if we are parsing arguments from the command line or from a file pragma.

## Available DynFlags

allNonDeprecatedFlags :: [String] #

All dynamic flags option strings without the deprecated ones. These are the user facing strings for enabling and disabling options.
