% This module defines the program listing which takes a mercury module
|
|
% and a predicate name, a function name or a type name and outputs the
|
|
% corresponding source code or hlds code in the file listing_output.
|
|
% It is intended to be used within the Mercury debuggers.
|
|
%
|
|
% Usage: listing <module_name> <pred_name>[.hlds_dump.*] [<arity>]
|
|
% If arity is not typed in, listing will display all the predicates
|
|
% pred_name/n. If the ".hlds_dump.*" extension is typed in, it will
|
|
% display the hlds code of the file <pred_name>.hlds_dump.*.
