Module Debug

module Debug: Debug

include Core_kernel.Debug

val am : Core_kernel.Std.Source_code_position.t -> unit

am, ams, and amf output a source code position and backtrace to stderr. amf accepts a printf-style format string. ams accepts a message, value, and sexp converter for that value. Typical usage looks like:

      ...;
      Debug.am _here_;
      ...;
      Debug.amf _here_ "hello (%s, %s)" (X.to_string x) (Y.to_string y);
      ...;
      Debug.ams _here_ "hello" (x, y) <:sexp_of< X.t * Y.t >>;
      ...;
    

The am* functions output source code positions in the standard format "FILE:LINE:COL", which means that one can use a tool like emacs grep-mode on a buffer containing debug messages to step through one's code by stepping through the messages.

val ams : Core_kernel.Std.Source_code_position.t ->
       string -> 'a -> ('a -> Core_kernel.Std.Sexp.t) -> unit

val amf : Core_kernel.Std.Source_code_position.t ->
       ('r, unit, string, unit) Pervasives.format4 -> 'r
