PROGRAM:
NAME
pbyacc - an LALR(1) parser generator
SYNOPSIS
pbyacc [ -CPcdlrtv ] [ -b file_prefix ] [ -p symbol_prefix ] filename
DESCRIPTION
pbyacc reads the grammar specification in the file filename and generates an LR(1) parser
for it. The parsers consist of a set of LALR(1) parsing tables and a driver routine
written in the C or Perl programming languages. pbyacc normally writes the parse tables
and the driver routine to the file y.tab.c, using the C programming language.
The following options are available:
-b file_prefix
The -b option changes the prefix prepended to the output file names to the
string denoted by file_prefix. The default prefix is the character y.
-C or -c
Use the C programming language (default).
-d The -d option causes the header file y.tab.h to be written (or y.tab.ph, for
Perl).
-l If the -l option is not specified, pbyacc will insert #line directives in
the generated code. The #line directives let the C compiler relate errors
in the generated code to the user's original code. If the -l option is
specified, pbyacc will not insert the #line directives. #line directives
specified by the user will be retained.
-p symbol_prefix
Change the prefix in symbols in the generated code to the string denoted by
symbol_prefix rather than the default of "yy". Only symbols generated by
pbyacc are affected. Symbols in the definition and user subroutine sections
are not changed.
The symbol_prefix can contain upper or lower case letters, digits, or _
(underline or underscore). It must start with either an underline or a
letter and must contain at least one lower case letter.
All lower case letters in the symbol prefix will be converted to upper case
letters when defined values or typedefs are generated.
For example, if '-p ftp_' is specifed on the pbyacc command line:
┌─────────────┬──────────────┐
│ old symbol │ new symbol │
├─────────────┼──────────────┤
│ YYABORT │ FTP_ABORT │
│ YYACCEPT │ FTP_ACCEPT │
│ YYBYACC │ FTP_BYACC │
│ YYDEBUG │ FTP_DEBUG │
│ YYSTYPE │ FTP_STYPE │
│ yyabort │ ftp_abort │
│ yyerrok │ ftp_errok │
│ yylex │ ftp_lex │
│ yylval │ ftp_lval │
│ yyparse │ ftp_parse │
Binary file (standard input) matches
