Module Builtin_attributes

Support for some of the builtin attributes

Warning: this module is unstable and part of compiler-libs.

val check_alerts : Location.t -> Parsetree.attributes -> string -> unit
val check_alerts_inclusion : def:Location.t -> use:Location.t -> Location.t -> Parsetree.attributes -> Parsetree.attributes -> string -> unit
val alerts_of_attrs : Parsetree.attributes -> Misc.alerts
val alerts_of_sig : Parsetree.signature -> Misc.alerts
val alerts_of_str : Parsetree.structure -> Misc.alerts
val check_deprecated_mutable : Location.t -> Parsetree.attributes -> string -> unit
val check_deprecated_mutable_inclusion : def:Location.t -> use:Location.t -> Location.t -> Parsetree.attributes -> Parsetree.attributes -> string -> unit
val check_no_alert : Parsetree.attributes -> unit
val error_of_extension : Parsetree.extension -> Location.error
val warning_attribute : ?⁠ppwarning:bool -> Parsetree.attribute -> unit

Apply warning settings from the specified attribute. "ocaml.warning"/"ocaml.warnerror" (and variants without the prefix) are processed and other attributes are ignored.

Also implement ocaml.ppwarning (unless ~ppwarning:false is passed).

val warning_scope : ?⁠ppwarning:bool -> Parsetree.attributes -> (unit -> 'a) -> 'a

Execute a function in a new scope for warning settings. This means that the effect of any call to warning_attribute during the execution of this function will be discarded after execution.

The function also takes a list of attributes which are processed with warning_attribute in the fresh scope before the function is executed.
