(** {6 Design note} *)
This module is meant to factorize code to create located error messages, for a
public or an internal audience.
This module uses internally the [passlib] which offers the opportunity to passes
and checkers to be more verbose and outputting a detailed context in the track
system, which can be analyzed after the compilation (or after the last error),
using [opatrack]
(** {6 Context} *)
module Context :
type context
(** Merging several context *)
val merge2 : context -> context -> context
val merge : context -> context list -> context
(** As we fail on surface ast, we have still all posititions from the user code *)
val pos : FilePos.pos -> context
(** Temporary, until we do the refactoring of pos in the Surface Ast *)
val label : 'a QmlLoc.label -> context
val annot : QmlLoc.annot -> context
(** if needed, add some other context constructors, and merge,
like [qmlError] *)
type context = Context.context
The documentation of these function is in [PassHandler] and [PassError]
(** {6 Interaction with Checkers} *)
(** *)
val check_fail : PassHandler.cond_id -> context -> ('a, 'error) OManager.oformat -> 'a
val scheck_fail : PassHandler.cond_id -> context -> ('a, unit) OManager.oformat -> 'a
(** {6 Interaction with Passes} *)
(** Internal Errors *)
(** *)
val cond_violation : PassHandler.cond_id -> context -> ('a, 'error) OManager.oformat -> 'a
val scond_violation : PassHandler.cond_id -> context -> ('a, unit) OManager.oformat -> 'a
val i_error : PassHandler.cond_id option -> context -> ('a, 'error) OManager.oformat -> 'a
val i_serror : PassHandler.cond_id option -> context -> ('a, unit) OManager.oformat -> 'a
(** Public Errors *)
(** *)
val error : context -> ('params, 'exit) OManager.oformat -> 'params
val serror : context -> ('params, unit) OManager.oformat -> 'params
val warning : wclass:WarningClass.wclass -> context -> ('params, unit) OManager.oformat -> 'params
