NAME

pepy - PE parser (yacc-based)

SYNOPSIS

pepy[-A][-a advise][-b prefix][-d][-h][-o module.c][-P][-p][-r][-s][-S section]module.py

cc ... module.c -lisode

DESCRIPTION

The pepy program reads a description of a presentation moduleand produces C routines to recognize and/or build the correspondingobjects.

The `-a' switch sets the name of the ``advise'' routine.

The `-b' switch generates a separate file for each generated routine,using the supplied prefix.

The `-d' switch directs pepy to ignore most pepy-styleaugmentations.

The `-h' switch enables additional heuristics when pepy generates aprinter.

The `-o' switch sets the name of the output file,which is normally derived from the name of the input file.The distinguished file ``-'' can be used to force the use of thestandard output.

The `-P' switch directs pepy not to include cpp-type linenumber information in the output.This is useful for debugging pepy (gasp!).

The `-p' switch directs pepy to remove the action statements from thedescription,and print the resulting information on the standard output;This typically results in a file suitable for pretty-printing.

The `-r' switch directs pepy to produce ``robust'' code.This tells pepy not to generate code to check for unknown or extraneousobjects.This is used for extensibility purposes.

Normally, pepy prints the name of each type as it works.The `-s' switch disables this behavior.

The `-S' switch sets the initial section-processing mode for pepy.The default is `-S DECODE' which causes pepy to generate a decoder.Other values are `-S ENCODE' to generate an encoder;or, `-S PRINT' to generate a printer.

The `-A' switch says that pepy should process all three modes.
