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.

data DiagnosticReason Source #
The reason why a Diagnostic
was emitted in the first place.
Diagnostic messages are born within GHC with a very precise reason, which
can be completely statically-computed (i.e. this is an error or a warning
no matter what), or influenced by the specific state of the DynFlags
at
the moment of the creation of a new Diagnostic
. For example, a parsing
error is always going to be an error, whereas a 'WarningWithoutFlag
Opt_WarnUnusedImports' might turn into an error due to '-Werror' or
'-Werror=warn-unused-imports'. Interpreting a DiagnosticReason
together
with its associated Severity
gives us the full picture.
WarningWithoutFlag | Born as a warning. |
WarningWithFlag !WarningFlag | Warning was enabled with the flag. |
ErrorWithoutFlag | Born as an error. |

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 GHC.Unit.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.

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.

i.e. if ~.ghc$UNIQUE_SUBDIR exists we use that otherwise we use $XDG_DATA_HOME/$UNIQUE_SUBDIR
UNIQUE_SUBDIR is typically a combination of the target platform and GHC version

Parsing DynFlags
parseDynamicFlagsCmdLine Source #
:: MonadIO m | |

Parse dynamic flags from a list of command line arguments. Returns
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 Source #

Like parseDynamicFlagsCmdLine

Used to parse flags set in a modules pragma.

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.
