The functions below can be used to parse Longident safely.
val longident : Lexing.lexbuf -> Longident.t
The function longident is guaranteed to parse all subclasses of Longident.t used in OCaml: values,
constructors, simple or extended module paths, and types or module types.
However, this function accepts inputs which are not accepted by the compiler, because they combine
functor applications and infix operators. In valid OCaml syntax, only value-level identifiers may end
with infix operators Foo.( + ) . Moreover, in value-level identifiers the module path Foo must be simple
( M.N rather than F(X) ): functor applications may only appear in type-level identifiers. As a
consequence, a path such as F(X).( + ) is not a valid OCaml identifier; but it is accepted by this
function.
The next functions are specialized to a subclass of Longident.t
val val_ident : Lexing.lexbuf -> Longident.t
This function parses a syntactically valid path for a value. For instance, x , M.x , and (+.) are valid.
Contrarily, M.A , F(X).x , and true are rejected.
Longident for OCaml's value cannot contain functor application. The last component of the Longident.t is
not capitalized, but can be an operator A.Path.To.(.%.%.(;..)<-)
val constr_ident : Lexing.lexbuf -> Longident.t
This function parses a syntactically valid path for a variant constructor. For instance, A , M.A and
M.(::) are valid, but both M.a and F(X).A are rejected.
Longident for OCaml's variant constructors cannot contain functor application. The last component of the
Longident.t is capitalized, or it may be one the special constructors: true , false , () , [] , (::) .
Among those special constructors, only (::) can be prefixed by a module path ( A.B.C.(::) ).
val simple_module_path : Lexing.lexbuf -> Longident.t
This function parses a syntactically valid path for a module. For instance, A , and M.A are valid, but
both M.a and F(X).A are rejected.
Longident for OCaml's module cannot contain functor application. The last component of the Longident.t
is capitalized.
val extended_module_path : Lexing.lexbuf -> Longident.t
This function parse syntactically valid path for an extended module. For instance, A.B and F(A).B are
valid. Contrarily, (.%()) or [] are both rejected.
The last component of the Longident.t is capitalized.
val type_ident : Lexing.lexbuf -> Longident.t
This function parse syntactically valid path for a type or a module type. For instance, A , t , M.t and
F(X).t are valid. Contrarily, (.%()) or [] are both rejected.
In path for type and module types, only operators and special constructors are rejected.
