Package jay.yydebug
invalid reference
jay
An implementation of yyDebug
is passed as
an additional argument to yyparse() to trace a Java-based
parser generated by
invalid reference
jay
yyDebugAdapter
produces one-line messages,
by default to standard output. The messages are designed to be
filtered by a program such as grep.
yyAnim
provides an animation of the parsing
process:

Terminal symbols are displayed in the token field as
they are read by the parser, state/value stack activities are
shown in the stack panel, and a running commentary appears
in the comments area. The text area at the bottom simulates
a terminal if the flags 1 for standard input and/or
2 for standard and diagnostic output are passed to yyAnim
.
The parser is stopped if there is an activity in an area with an activated checkbutton. continue will continue the parsing activities.
- Can a skeleton be written which uses the debug interface
to call the action interface created by
invalid reference

- Animation is not (yet?) available for C#.

- 1.1.0, August 2004.
