Agda.Syntax.Concrete.Definitions

Description

Preprocess Declarations, producing NiceDeclarations.

Attach fixity and syntax declarations to the definition they refer to.
Distribute the following attributes to the individual definitions: abstract, instance, postulate, primitive, private, termination pragmas.
Gather the function clauses belonging to one function definition.
Expand ellipsis ... in function clauses following with.
Infer mutual blocks. A block starts when a lone signature is encountered, and ends when all lone signatures have seen their definition.
Handle interleaved mutual blocks. In an `interleaved mutual' block we:
leave the data and fun sigs in place
classify signatures in constructor block based on their return type and group them all as a data def at the position in the block where the first constructor for the data sig in question occured
classify fun clauses based on the declared function used and group them all as a fundef at the position in the block where the first such fun clause appeared
Report basic well-formedness error, when one of the above transformation fails. When possible, errors should be deferred to the scope checking phase (ConcreteToAbstract), where we are in the TCM and can produce more informative error messages.

data NiceDeclaration Source #

The nice declarations. No fixity declarations and function definitions are contained in a single constructor instead of spread out between type signatures and clauses. The private, postulate, abstract and instance modifiers have been distributed to the individual declarations.

NiceFunClause Range Access IsAbstract TerminationCheck CoverageCheck Catchall Declaration	An uncategorized function clause, could be a function clause without type signature or a pattern lhs (e.g. for irrefutable let). The `Declaration` is the actual `FunClause`.
FunSig Range Access IsAbstract IsInstance IsMacro ArgInfo TerminationCheck CoverageCheck Name Expr
FunDef Range [Declaration] IsAbstract IsInstance TerminationCheck CoverageCheck Name [Clause]	Block of function clauses (we have seen the type signature before). The `Declaration`s are the original declarations that were processed into this `FunDef` and are only used in `notSoNiceDeclaration`. Andreas, 2017-01-01: Because of issue #2372, we add `IsInstance` here. An alias should know that it is an instance.
