data UniqSupply Source #

Unique Supply

A value of type UniqSupply is unique, and it can supply one distinct Unique. Also, from the supply, one can also manufacture an arbitrary number of further UniqueSupply values, which will be distinct from the first and from all others.

getPmNablas :: DsM Nablas Source #

Get the current pattern match oracle state. See dsl_nablas.

updPmNablas :: Nablas -> DsM a -> DsM a Source #

Set the pattern match oracle state within the scope of the given action. See dsl_nablas.

dsGetCompleteMatches :: DsM DsCompleteMatches Source #

The COMPLETE pragmas that are in scope.

diagnosticDs :: DsMessage -> DsM () Source #

Emit a diagnostic for the current source location. In case the diagnostic is a warning, the latter will be ignored and discarded if the relevant WarningFlag is not set in the DynFlags. See Note [Discarding Messages] in Error.

errDsCoreExpr :: DsMessage -> DsM CoreExpr Source #

Issue an error, but return the expression for (), so that we can continue reporting errors.

Fields

  • eqn_pat :: LPat GhcTc

    The first pattern of the equation

    NB: The location info is used to determine whether the pattern is generated or not. This helps us avoid warnings on patterns that GHC elaborated.

    NB: We have already applied decideBangHood to this pattern. See Note [decideBangHood] in GHC.HsToCore.Utils

  • eqn_rest :: EquationInfo

    The rest of the equation after its first pattern

data MatchResult a Source #

This is a value of type a with potentially a CoreExpr-shaped hole in it. This is used to deal with cases where we are potentially handling pattern match failure, and want to later specify how failure is handled.

Constructors

MR_Infallible (DsM a)

We represent the case where there is no hole without a function from CoreExpr, like this, because sometimes we have nothing to put in the hole and so want to be sure there is in fact no hole.

MR_Fallible (CoreExpr -> DsM a) 

Instances

Applicative MatchResult Source #

Product is an "or" on fallibility---the combined match result is infallible only if the left and right argument match results both were.

This is useful for combining a bunch of alternatives together and then getting the overall fallibility of the entire group. See mkDataConCase for an example.

Arguments

:: String

header

-> SDoc

information to output

-> CoreExpr

expression

-> DsM CoreExpr 

Inject a trace message into the compiled program. Whereas pprTrace prints out information *while compiling*, pprRuntimeTrace captures that information and causes it to be printed *at runtime* using Debug.Trace.trace.

pprRuntimeTrace hdr doc expr

will produce an expression that looks like

trace (hdr + doc) expr

When using this to debug a module that Debug.Trace depends on, it is necessary to import {-# SOURCE #-} Debug.Trace () in that module. We could avoid this inconvenience by wiring in Debug.Trace.trace, but that doesn't seem worth the effort and maintenance cost.
