Log Machinery

include Plugin.S
include Log.Messages
type category

category for debugging/verbose messages. Must be registered before any use. Each column in the string defines a sub-category, e.g. a:b:c defines a subcategory c of b, which is itself a subcategory of a. Enabling a category (via -plugin-msg-category) will enable all its subcategories.

  • since Fluorine-20130401
type warn_category

Same as above, but for warnings

  • since Chlorine-20180501
val verbose_atleast : int -> bool
  • since Beryllium-20090601-beta1
val debug_atleast : int -> bool
  • since Beryllium-20090601-beta1
val printf : ?level:int -> ?dkey:category -> ?current:bool -> ?source:Filepath.position -> ?append:(Stdlib.Format.formatter -> unit) -> ?header:(Stdlib.Format.formatter -> unit) -> ('a, Stdlib.Format.formatter, unit) Stdlib.format -> 'a

Outputs the formatted message on stdout. Levels and key-categories are taken into account like event messages. The header formatted message is emitted as a regular result message.

val result : ?level:int -> ?dkey:category -> 'a Log.pretty_printer

Results of analysis. Default level is 1.

  • since Beryllium-20090601-beta1
val has_tty : unit -> bool

Returns true is this Log's channel is in console mode

val feedback : ?ontty:Log.ontty -> ?level:int -> ?dkey:category -> 'a Log.pretty_printer

Progress and feedback. Level is tested against the verbosity level.

  • since Beryllium-20090601-beta1
val debug : ?level:int -> ?dkey:category -> 'a Log.pretty_printer

Debugging information dedicated to Plugin developers. Default level is 1. The debugging key is used in message headers. See also set_debug_keys and set_debug_keyset.

  • since Beryllium-20090601-beta1
val warning : ?wkey:warn_category -> 'a Log.pretty_printer

Hypothesis and restrictions.

  • since Beryllium-20090601-beta1
val error : 'a Log.pretty_printer

user error: syntax/typing error, bad expected input, etc.

  • since Beryllium-20090601-beta1
val abort : ('a, 'b) Log.pretty_aborter

user error stopping the plugin.

  • raises AbortError

    with the channel name.

  • since Beryllium-20090601-beta1
val failure : 'a Log.pretty_printer

internal error of the plug-in.

val fatal : ('a, 'b) Log.pretty_aborter

internal error of the plug-in.

  • raises AbortFatal

    with the channel name.

  • since Beryllium-20090601-beta1
val verify : bool -> ('a, bool) Log.pretty_aborter

If the first argument is true, return true and do nothing else, otherwise, send the message on the fatal channel and return false.

The intended usage is: assert (verify e "Bla...") ;.

  • since Beryllium-20090601-beta1
val not_yet_implemented : ?current:bool -> ?source:Filepath.position -> ('a, Stdlib.Format.formatter, unit, 'b) Stdlib.format4 -> 'a

raises FeatureRequest but does not send any message. If the exception is not caught, Frama-C displays a feature-request message to the user.

  • since Beryllium-20090901
  • before 23.0-Vanadium

    there was no current and source arguments.

val deprecated : string -> now:string -> ('a -> 'b) -> 'a -> 'b

deprecated s ~now f indicates that the use of f of name s is now deprecated. It should be replaced by now.

  • returns

    the given function itself

  • since Lithium-20081201 in Extlib
  • since Beryllium-20090902
val with_result : (Log.event option -> 'b) -> ('a, 'b) Log.pretty_aborter

with_result f fmt calls f in the same condition as logwith.

  • since Beryllium-20090601-beta1
val with_warning : (Log.event option -> 'b) -> ('a, 'b) Log.pretty_aborter

with_warning f fmt calls f in the same condition as logwith.

  • since Beryllium-20090601-beta1
val with_error : (Log.event option -> 'b) -> ('a, 'b) Log.pretty_aborter

with_error f fmt calls f in the same condition as logwith.

  • since Beryllium-20090601-beta1
val with_failure : (Log.event option -> 'b) -> ('a, 'b) Log.pretty_aborter

with_failure f fmt calls f in the same condition as logwith.

  • since Beryllium-20090601-beta1
val log : ?kind:Log.kind -> ?verbose:int -> ?debug:int -> 'a Log.pretty_printer

Generic log routine. The default kind is Result. Use cases (with n,m > 0):

  • log ~verbose:n: emit the message only when verbosity level is at least n.
  • log ~debug:n: emit the message only when debugging level is at least n.
  • log ~verbose:n ~debug:m: any debugging or verbosity level is sufficient.
  • since Beryllium-20090901
val logwith : (Log.event option -> 'b) -> ?wkey:warn_category -> ?emitwith:(Log.event -> unit) -> ?once:bool -> ('a, 'b) Log.pretty_aborter

Recommanded generic log routine using warn_category instead of kind. logwith continuation ?wkey fmt similar to warning ?wkey fmt and then calling the continuation. The optional continuation argument refers to the corresponding event. None is used iff no message is logged. In case the wkey is considered as a Failure, the continution is not called. This kind of message denotes a fatal error aborting Frama-C. Notice that the ~emitwith action is called iff a message is logged.

  • since 18.0-Argon
val register : Log.kind -> (Log.event -> unit) -> unit

Local registry for listeners.

val register_tag_handlers : ((string -> string) * (string -> string)) -> unit

Functors for late option registration

Kernel_function-related options cannot be registered in this module: They depend on Globals, which is linked later. We provide here functors to declare them after Globals
