addConstant :: QName -> Definition -> TCM ()

Add a constant to the signature. Lifts the definition to top level.

addConstant' :: QName -> ArgInfo -> QName -> Type -> Defn -> TCM ()

A combination of addConstant and defaultDefn. The Language does not need to be supplied.

setTerminates :: QName -> Bool -> TCM ()

Set termination info of a defined function symbol.

setCompiledClauses :: QName -> CompiledClauses -> TCM ()

Set CompiledClauses of a defined function symbol.

setSplitTree :: QName -> SplitTree -> TCM ()

Set SplitTree of a defined function symbol.

modifyFunClauses :: QName -> ([Clause] -> [Clause]) -> TCM ()

Modify the clauses of a function.

addClauses :: QName -> [Clause] -> TCM ()

Lifts clauses to the top-level and adds them to definition. Also adjusts the funCopatternLHS field if necessary.

mkPragma :: String -> TCM CompilerPragma

addPragma :: BackendName -> QName -> String -> TCM ()

Add a compiler pragma `{-# COMPILE backend name text #-}`

getUniqueCompilerPragma :: BackendName -> QName -> TCM (Maybe CompilerPragma)

setFunctionFlag :: FunctionFlag -> Bool -> QName -> TCM ()

markStatic :: QName -> TCM ()

markInline :: Bool -> QName -> TCM ()

markInjective :: QName -> TCM ()

unionSignatures :: [Signature] -> Signature

addSection :: ModuleName -> TCM ()

Add a section to the signature.

The current context will be stored as the cumulative module parameters for this section.

setModuleCheckpoint :: ModuleName -> TCM ()

Sets the checkpoint for the given module to the current checkpoint.

getSection :: (Functor m, ReadTCState m) => ModuleName -> m (Maybe Section)

Get a section.

Why Maybe? The reason is that we look up all prefixes of a module to compute number of parameters, and for hierarchical top-level modules, A.B.C say, A and A.B do not exist.

lookupSection :: (Functor m, ReadTCState m) => ModuleName -> m Telescope

Lookup a section telescope.

If it doesn't exist, like in hierarchical top-level modules, the section telescope is empty.

addDisplayForms :: QName -> TCM ()

Add display forms for a name f copied by a module application. Essentially if f can reduce to

λ xs → A.B.C.f vs

by unfolding module application copies (defCopy), then we add a display form

A.B.C.f vs ==> f xs

applySection

Arguments

:: ModuleName

Name of new module defined by the module macro.

-> Telescope

Parameters of new module.

-> ModuleName

Name of old module applied to arguments.

-> Args

Arguments of module application.

-> ScopeCopyInfo

-> TCM ()

Module application (followed by module parameter abstraction).

applySection' :: ModuleName -> Telescope -> ModuleName -> Args -> ScopeCopyInfo -> TCM ()

moduleParamsToApply :: (Functor m, Applicative m, HasOptions m, MonadTCEnv m, ReadTCState m, MonadDebug m) => ModuleName -> m Args

We have to insert the module telescope of the common prefix of the current module and the module where the definition comes from. (Properly raised to the current context.)

Example: module M₁ Γ where module M₁ Δ where f = ... module M₃ Θ where ... M₁.M₂.f [insert Γ raised by Θ]

inFreshModuleIfFreeParams :: TCM a -> TCM a

Unless all variables in the context are module parameters, create a fresh module to capture the non-module parameters. Used when unquoting to make sure generated definitions work properly.

inAbstractMode :: MonadTCEnv m => m a -> m a

Enter abstract mode. Abstract definition in the current module are transparent.

inConcreteMode :: MonadTCEnv m => m a -> m a

Not in abstract mode. All abstract definitions are opaque.

ignoreAbstractMode :: MonadTCEnv m => m a -> m a

Ignore abstract mode. All abstract definitions are transparent.

inConcreteOrAbstractMode :: (MonadTCEnv m, HasConstInfo m) => QName -> (Definition -> m a) -> m a

Enter concrete or abstract mode depending on whether the given identifier is concrete or abstract.

treatAbstractly :: MonadTCEnv m => QName -> m Bool

Check whether a name might have to be treated abstractly (either if we're inAbstractMode or it's not a local name). Returns true for things not declared abstract as well, but for those makeAbstract will have no effect.

treatAbstractly' :: QName -> TCEnv -> Bool

Andreas, 2015-07-01: If the current module is a weak suffix of the identifier module, we can see through its abstract definition if we are abstract. (Then treatAbstractly' returns False).

If I am not mistaken, then we cannot see definitions in the where block of an abstract function from the perspective of the function, because then the current module is a strict prefix of the module of the local identifier. This problem is fixed by removing trailing anonymous module name parts (underscores) from both names.

isInlineFun :: Defn -> Bool

Is it a function marked INLINE?

isProperProjection :: Defn -> Bool

Returns True if we are dealing with a proper projection, i.e., not a projection-like function nor a record field value (projection applied to argument).

projectionArgs :: Definition -> Int

Number of dropped initial arguments of a projection(-like) function.

usesCopatterns :: HasConstInfo m => QName -> m Bool

Check whether a definition uses copatterns.

applyDef :: HasConstInfo m => ProjOrigin -> QName -> Arg Term -> m Term

Apply a function f to its first argument, producing the proper postfix projection if f is a projection which is not irrelevant.
