Bison 3.2.1 released [stable]

Item posted by Akim Demaille <akim> on Sat 10 Nov 2018 06:56:33 AM UTC.

We would have been happy not to have to announce the release of Bison 3.2.1,
which fixes portability issues of Bison 3.2.

Bison 3.2 brought massive improvements to the deterministic C++ skeleton, When variants are enabled and the compiler supports C++11 or
better, move-only types can now be used for semantic values. C++98 support
is not deprecated. Please see the NEWS below for more details.

Many thanks to Frank Heckenbach for paving the way for this release with his
implementation of a skeleton in C++17, and to Nelson H. F. Beebe for testing
exhaustively portability issues.


Bison is a general-purpose parser generator that converts an annotated
context-free grammar into a deterministic LR or generalized LR (GLR) parser
employing LALR(1) parser tables. Bison can also generate IELR(1) or
canonical LR(1) parser tables. Once you are proficient with Bison, you can
use it to develop a wide range of language parsers, from those used in
simple desk calculators to complex programming languages.

Bison is upward compatible with Yacc: all properly-written Yacc grammars
ought to work with Bison with no change. Anyone familiar with Yacc should be
able to use Bison with little trouble. You need to be fluent in C or C++
programming in order to use Bison. Java is also supported.

Here are the compressed sources: (4.1MB) (2.1MB)

Here are the GPG detached signatures[*]:

Use a mirror for higher download bandwidth:

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:

gpg --verify bison-3.2.1.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

gpg --keyserver --recv-keys 0DDCAA3278D5264E

and rerun the 'gpg --verify' command.

This release was bootstrapped with the following tools:
Autoconf 2.69
Automake 1.16.1
Flex 2.6.4
Gnulib v0.1-2176-ga79f2a287
