kmyacc version 4.1.4 (2006/02/15) ================================= kmyacc is an LALR(1) parser generator, hopefully compatible with AT&T yacc. Features: - Generates smaller table than Yacc/Berkeley yacc/Bison. - Supports multi-language (currenly C and Java). INSTALL ======= (1) You must have ANSI C compiler. (2) Read Makefile and change macro BIN and PARLIB appropriately. (3) Type make make install HOW TO USE ========== Command kmyacc foo.y generates parser code "y.tab.c", same as original yacc. Command kmyacc Foo.jy creates parser code "Foo.java", its class name is "Foo". Synopsys: kmyacc [ -dvltani ] [ -b X ] [ -p XX ] [ -m MODEL ] [ -L LANG ] grammar Options: -d Makes definition file named y.tab.h, which contains definitions of token values and the type of semantic stack. (C language only) -v Generates file y.output which contains human-readable parser tables and diagnostics. -l Does not insert #line control directives in y.tab.c. -t Generates debugging code. Compiling with -DYYDEBUG option gives the same effect. -a Makes semantic actions individual functions rather than blocks in one switch statement. This option is useful if your compiler can not compile big functions/methods. -b X Uses X rather than y as the prefix of generated filenames. X.tab.c for C, X.java for Java. -p XX Uses XX rather than yy as the prefix of global identifiers in the parser. You can avoid collision of external symbols when you use more than one parser in the same program by specifing this option. (C language only) -m MODEL Uses file MODEL as prototype of parser code. When defaulted, file /usr/local/lib/kmyacc.LANG.parser is taken, where LANG is a host language name deduced from source file extension(.y/.jy), or one specified by -L switch explicitly. -L LANG Specifies LANG as host programming language. c,java,javascript,perl are available. -n Allows referencing semantic values by name. -i Inhibits referencing semantic values by $$, $1, $2 form. Environment KMYACCPAR Prototype file name. Same as -m option. Differences between kmyacc and AT&T yacc ======================================== - Options -b, -p, -a, -m, -L added - Bison's %expect, %pure_parser statement added - Treat // as comment - Following obsolete features deleted o literal tokens surrounded by " o \left, \right etc. o %<, %>, %binary, %2, %0, %= - YYBACKUP macro not supported COPYRIGHT ========= Copyright (C) 1987,1989,1992,1993,2005,2006 MORI Koichiro.
