yyextract — extract grammar rules from a yacc grammar
yyextract [-behyV] [-o file] [-t title] [-w cols] [file ...]
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.
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 ']').
