Module Notation_term

notation_constr

notation_constr is the subtype of glob_constr allowed in syntactic extensions (i.e. notations). No location since intended to be substituted at any place of a text. Complex expressions such as fixpoints and cofixpoints are excluded, as well as non global expressions such as existential variables.

type notation_constr =
| NRef of Names.GlobRef.t * Glob_term.glob_level list option
| NVar of Names.Id.t
| NApp of notation_constr * notation_constr list
| NProj of Names.Constant.t * Glob_term.glob_level list option * notation_constr list * notation_constr

| NLambda of Names.Name.t * notation_constr option * notation_constr
| NProd of Names.Name.t * notation_constr option * notation_constr

| NRec of Glob_term.glob_fix_kind * Names.Id.t array * (Names.Name.t * notation_constr option * notation_constr) list array * notation_constr array * notation_constr array
| NSort of Glob_term.glob_sort
| NCast of notation_constr * Constr.cast_kind * notation_constr
| NInt of Uint63.t
| NFloat of Float64.t
| NArray of notation_constr array * notation_constr * notation_constr

Note concerning NList: first constr is iterator, second is terminator; first id is where each argument of the list has to be substituted in iterator and snd id is alternative name just for printing; boolean is associativity

Types concerning notations

type scope_name = string
type tmp_scope_name = scope_name
type subscopes = tmp_scope_name list * scope_name list
type extended_subscopes = Constrexpr.notation_entry_level * subscopes

Type of the meta-variables of an notation_constr: in a recursive pattern x..y, x carries the sequence of objects bound to the list x..y

type constr_as_binder_kind =
| AsIdent
| AsName
| AsNameOrPattern
| AsStrictPattern
type notation_binder_source =
| NtnParsedAsPattern of bool
| NtnParsedAsIdent
| NtnParsedAsName
| NtnBinderParsedAsConstr of constr_as_binder_kind
| NtnParsedAsBinder
type notation_var_instance_type =
| NtnTypeConstr
| NtnTypeBinder of notation_binder_source
| NtnTypeConstrList
| NtnTypeBinderList
type notation_var_internalization_type =
| NtnInternTypeAny of scope_name option
| NtnInternTypeOnlyBinder

Type of variables when interpreting a constr_expr as a notation_constr: in a recursive pattern x..y, both x and y carry the individual type of each element of the list x..y

This characterizes to what a notation is interpreted to
