Location.Error
For a detailed explanation on error reporting, refer to the relevant part of the tutorial.
val message : t -> string
val register_error_of_exn : (exn -> t option) -> unit
Register an exception handler. Exception registered this way will be properly displayed by report_exception
.
val of_exn : exn -> t option
val to_extension :
t ->
string Astlib.Location.loc * Astlib.Ast_502.Parsetree.payload
Convert an error to an extension point. The compiler recognizes this and displays the error properly.
val raise : t -> 'a
Raise a compiler Parsing.Location.Error
exception. The composition of Location.Error.createf
with Location.Error.raise
is the same as Location.raise_errorf
.
Update where the error is located. The old location will be overwritten.
val of_extension :
(string Astlib.Location.loc * Astlib.Ast_502.Parsetree.payload) ->
t option
Convert an extension point to an error. Extension points must have the exact form as created by to_extension
.
