NAME
yyextract - extract grammar rules from a yacc grammar
SYNOPSIS
yyextract [-behyV] [-o file] [-t title] [-w cols] [file ...]
DESCRIPTION
The yyextract utility extracts the grammar rules from a yacc grammar.
The options are as follows:
-b Select the Backus-Naur Form (BNF) for the output.
-e Select the Extended Backus-Naur Form (EBNF) for the output.
-h Output in HTML format.
-o file
Set the output destination to file.
-t title
Specify the page title for the generated HTML page.
-w cols
Set the width limit of the output (this sets only the width of
the %token header).
-y Select the yacc format for the output. This is the default
format.
-V Print version information on standard output then exit.
NOTES
The Extended Backus-Naur Form (EBNF) is like the Backus-Naur Form (BNF)
but with the empty rules translated with the zero-or-one operator (within
the brackets ’[’ and ’]’).
