Modifying the context
modifyContextEntry :: (Dom (Name, Type) -> Dom (Name, Type)) -> ContextEntry -> ContextEntry Source #
Modify the ctxEntry
field of a ContextEntry
.
modifyContextEntries :: (Dom (Name, Type) -> Dom (Name, Type)) -> Context -> Context Source #
Modify all ContextEntry
s.
modifyContext :: MonadTCM tcm => (Context -> Context) -> tcm a -> tcm a Source #
Modify a Context
in a computation.
mkContextEntry :: MonadTCM tcm => Dom (Name, Type) -> tcm ContextEntry Source #
inTopContext :: MonadTCM tcm => tcm a -> tcm a Source #
Change to top (=empty) context.
TODO: currently, this makes the ModuleParamDict
ill-formed!
escapeContext :: MonadTCM tcm => Int -> tcm a -> tcm a Source #
Delete the last n
bindings from the context.
TODO: currently, this makes the ModuleParamDict
ill-formed!
Manipulating module parameters --
withModuleParameters :: ModuleParamDict -> TCM a -> TCM a Source #
Locally set module parameters for a computation.
updateModuleParameters :: MonadTCM tcm => Substitution -> tcm a -> tcm a Source #
Apply a substitution to all module parameters.
weakenModuleParameters :: MonadTCM tcm => Nat -> tcm a -> tcm a Source #
Since the ModuleParamDict
is relative to the current context,
this function should be called everytime the context is extended.
getModuleParameterSub :: MonadTCM tcm => ModuleName -> tcm Substitution Source #
Get substitution Γ ⊢ ρ : Γm
where Γ
is the current context
and Γm
is the module parameter telescope of module m
.
In case the current ModuleParamDict
does not know m
,
we return the identity substitution.
This is ok for instance if we are outside module m
(in which case we have to supply all module parameters to any
symbol defined within m
we want to refer).
Adding to the context
addCtx :: MonadTCM tcm => Name -> Dom Type -> tcm a -> tcm a Source #
addCtx x arg cont
add a variable to the context.
Chooses an unused Name
.
Warning: Does not update module parameter substitution!
unshadowName :: MonadTCM tcm => Name -> tcm Name Source #
Pick a concrete name that doesn't shadow anything in the context.
class AddContext b where Source #
Various specializations of addCtx
.
addContext :: MonadTCM tcm => b -> tcm a -> tcm a Source #
contextSize :: b -> Nat Source #
AddContext String Source # | |
AddContext Name Source # | |
AddContext Telescope Source # | |
AddContext a => AddContext [a] Source # | |
AddContext (Dom (String, Type)) Source # | |
AddContext (Dom (Name, Type)) Source # | |
AddContext (Dom Type) Source # | |
AddContext ([WithHiding Name], Dom Type) Source # | |
AddContext ([Name], Dom Type) Source # | |
AddContext (String, Dom Type) Source # | |
AddContext (Name, Dom Type) Source # | |
addContext' :: (MonadTCM tcm, AddContext b) => b -> tcm a -> tcm a Source #
Since the module parameter substitution is relative to the current context, we need to weaken it when we extend the context. This function takes care of that.
underAbstraction :: (Subst t a, MonadTCM tcm) => Dom Type -> Abs a -> (a -> tcm b) -> tcm b Source #
Go under an abstraction.
underAbstraction_ :: (Subst t a, MonadTCM tcm) => Abs a -> (a -> tcm b) -> tcm b Source #
Go under an abstract without worrying about the type to add to the context.
addLetBinding :: MonadTCM tcm => ArgInfo -> Name -> Term -> Type -> tcm a -> tcm a Source #
Add a let bound variable.
Querying the context
getContext :: MonadReader TCEnv m => m [Dom (Name, Type)] Source #
Get the current context.
getContextSize :: (Applicative m, MonadReader TCEnv m) => m Nat Source #
Get the size of the current context.
getContextArgs :: (Applicative m, MonadReader TCEnv m) => m Args Source #
Generate [var (n - 1), ..., var 0]
for all declarations in the context.
getContextTerms :: (Applicative m, MonadReader TCEnv m) => m [Term] Source #
Generate [var (n - 1), ..., var 0]
for all declarations in the context.
getContextTelescope :: (Applicative m, MonadReader TCEnv m) => m Telescope Source #
Get the current context as a Telescope
.
getContextId :: MonadReader TCEnv m => m [CtxId] Source #
Check if we are in a compatible context, i.e. an extension of the given context.
getContextNames :: (Applicative m, MonadReader TCEnv m) => m [Name] Source #
Get the names of all declarations in the context.
lookupBV :: MonadReader TCEnv m => Nat -> m (Dom (Name, Type)) Source #
get type of bound variable (i.e. deBruijn index)
typeOfBV' :: (Applicative m, MonadReader TCEnv m) => Nat -> m (Dom Type) Source #
typeOfBV :: (Applicative m, MonadReader TCEnv m) => Nat -> m Type Source #
nameOfBV :: (Applicative m, MonadReader TCEnv m) => Nat -> m Name Source #
getVarInfo :: MonadReader TCEnv m => Name -> m (Term, Dom Type) Source #
Get the term corresponding to a named variable. If it is a lambda bound variable the deBruijn index is returned and if it is a let bound variable its definition is returned.
