Berkeley Yacc

Berkeley Yacc is the best yacc variant available for Linux systems, compared to bison.

Also known as byacc, Berkeley Yacc is able to avoid dependencies of a peculiar compiler.

What is new in this release:

• yacc.1: document %token-table, improve presentation of double-quotes
• test/calc.tab.c, test/calc1.tab.c, test/calc2.tab.c, test/calc3.tab.c, test/code_calc.code.c, test/code_calc.tab.c, test/code_error.code.c, test/code_error.tab.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c, test/pure_calc.tab.c, test/pure_error.tab.c, test/quote_calc-s.tab.c, test/quote_calc.tab.c, test/quote_calc2-s.tab.c, test/quote_calc2.tab.c, test/quote_calc3-s.tab.c, test/quote_calc3.tab.c, test/quote_calc4-s.tab.c, test/quote_calc4.tab.c: regen
• output.c, skeleton.c: amend the last change so that yytname is #define'd as needed rather than permanent - to avoid breaking cproto for instance.
• output.c, defs.h, main.c, reader.c, skeleton.c: changes to build ntpd using byacc:
• rename yyname[] to yytname[]
• add YYTRANSLATE() macro
• recognize bison's %token-table declaration
• configure: regen
• yacc.1: s/EE/XE/ to work around groff bug on Debian 6
• makefile.in: use CF_MAKE_DOCS
• aclocal.m4: add CF_MAKE_DOCS
• configure.in: use CF_MAKE_DOCS

What is new in version 20130304:

• package/debian/changelog, VERSION, package/byacc.spec: bump
• aclocal.m4: adapt tweak from Dave Becket to work around long-ago breakage in "new" autoconf.
• output.c: fix bogus #include if "-i" is given but not "-d" (report by Richard Mitton).
• also while testing that, found a case where the union_file is unused; added a check for address that.
• test/ftp.output, test/ftp.tab.c, test/ftp.tab.h: regen
• test/ftp.y: fix most compiler warnings for "make check_make"
• test/calc1.tab.c: regen
• test/calc1.y: fix most compiler warnings for "make check_make"
• test/calc.tab.c, test/calc1.tab.c, test/calc2.tab.c, test/calc3.tab.c, test/code_calc.code.c, test/code_error.code.c, test/error.tab.c, test/ftp.tab.c, test/grammar.tab.c, test/pure_calc.tab.c, test/pure_error.tab.c, test/quote_calc-s.tab.c, test/quote_calc.tab.c, test/quote_calc2-s.tab.c, test/quote_calc2.tab.c, test/quote_calc3-s.tab.c, test/quote_calc3.tab.c, test/quote_calc4-s.tab.c, test/quote_calc4.tab.c: regen
• skeleton.c: quiet a gcc conversion-warning in yygrowstack()
• configure: regen
• aclocal.m4: another fix for CF_GCC_VERSION to handle Debian's modification of gcc message.

What is new in version 20121003:

• This version alters the configure script to allow experimentation with different autoconf versons (no code changes).

What is new in version 20120526:

• This version adds minor changes to easily build on FreeBSD and for other packagers who prefer not to use the configure script.

What is new in version 20101229:

• Several minor fixes/improvements from NetBSD.

What is new in version 20101226:

• defs.h, main.c: change return-type of allocate() to avoid warnings of alignment problems
• main.c: Solaris declares chmod() in
• configure: regen
• main.c: ifdef'd use of fcntl.h
• configure.in: add configure checks for fcntl.h, atexit and mkstemp
• main.c: for cases where mkstemp() is not available, use tempnam/open
• aclocal.m4: add CF_MKSTEMP
• aclocal.m4: improve quoting, deprecate ${name-value} in favor of standard ${name:-value}

What is new in version 20101126:

• package/byacc.spec, package/debian/changelog, VERSION: bump
• output.c:corrected use of %parse-param value in yyerror(); it doesn't use &yylva (report by Clifford Yapp)

What is new in version 20101122:

• output.c: add ifdef to guard against redefinition of YYSTYPE union (request by Clifford Yapp).
• test/calc1.tab.c: regen
• test/calc1.y: cleanup compiler warnings
• test/grammar.y: add "%expect"
• test/calc1.tab.h: regen * test/calc1.output, test/calc1.tab.c, test/calc1.tab.h: RCS_BASE test/calc2.tab.c, test/calc3.tab.c: regen
• test/calc1.y: advanced example from Steve Johnson's paper, uses unions
• test/calc3.y, test/calc2.y: init 'base', so examples can run
• test/ftp.tab.c, test/ftp.y: tweaks to compile with g++
• output.c: compensate for fix in reader.c
• reader.c: add/use putc_both() and puts_both(), incidentally fixing a place where a union copied to the union_file may be missing the end of the last line.
• package/debian/changelog, package/byacc.spec, VERSION: bump

What is new in version 20090221:

• The declaration of yylval was restored to the skeleton, as it was omitted in the fixes made in 20080824.
