Module Catala_utils.Uid

Global identifiers factories using a generative functor

module type Info = sig ... end

The information carried in global identifiers

module MarkedString : Info with type info = string Mark.pos

The only kind of information carried in Catala identifiers is the original string of the identifier annotated with the position where it is declared or used.

module type Id = sig ... end

Identifiers have abstract types, but are comparable so they can be used as keys in maps or sets. Their underlying information can be retrieved at any time.

module type Style = sig ... end

Used to define a consistent specific style when printing the different kinds of uids

module Make (X : Info) (_ : Style) () : Id with type info = X.info

This is the generative functor that ensures that two modules resulting from two different calls to Make will be viewed as different types t by the OCaml typechecker. Prevents mixing up different sorts of identifiers.

module Gen (_ : Style) () : Id with type info = MarkedString.info

Shortcut for creating a kind of uids over marked strings

Handling of Uids with additional path information

module Module : sig ... end
module Path : sig ... end
module type Qualified = sig ... end
module Gen_qualified (_ : Style) () : Qualified

Same as Gen but also registers path information
