We are pleased to announce GNU Guile release 1.9.14. This may be the last pre-release before the 2.0 release.
It provides many new noteworthy features, most notably the addition of a compiler and virtual machine. We encourage you to test them and provide feedback to `guile-de...@gnu.org'. The Guile web page is located at http://gnu.org/software/guile/, and among other things, it contains a link to the Guile FAQ and pointers to the mailing lists. Guile is an implementation of the Scheme programming language, with support for many SRFIs, packaged for use in a wide variety of environments. In addition to implementing the R5RS Scheme standard and a large subset of R6RS, Guile includes a module system, full access to POSIX system calls, networking support, multiple threads, dynamic linking, a foreign function call interface, and powerful string processing. Guile can run interactively, as a script interpreter, and as a Scheme compiler to VM bytecode. It is also packaged as a library so that applications can easily incorporate a complete Scheme interpreter/VM. An application can use Guile as an extension language, a clean and powerful configuration language, or as multi-purpose "glue" to connect primitives provided by the application. It is easy to call Scheme code From C code and vice versa. Applications can add new functions, data types, control structures, and even syntax to Guile, to create a domain-specific language tailored to the task at hand.

First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify guile-1.9.14.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 keys.gnupg.net --recv-keys EA52ECF4 and rerun the `gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.68 Automake 1.11.1 Libtool 2.4 Gnulib v0.0-4496-g6491120 This is a new release series with many new features and differences compared to 1.8. The complete list of changes compared to the 1.8.x series is available in the `NEWS' file. Changes since the 1.9.13 pre-release: ** New module: `(ice-9 futures)'. See "Futures" in the manual, for more information. ** Add bindings to GNU `sched_setaffinity' and `sched_getaffinity'. See "Processes" in the manual, for more information. ** New module `(srfi srfi-38)', External Representation for Data With Shared Structure See "SRFI-38" in the manual, for more information. Thanks to Andreas Rottmann. ** New module: `(web uri)', URI data type, parser, and unparser ** New module: `(web http)', HTTP header parsers and unparsers ** New module: `(web request)', HTTP request data type, reader, and writer ** New module: `(web response)', HTTP response data type, reader, and writer ** New module: `(web server)', Generic HTTP server ** New module: `(ice-9 poll)', a poll wrapper ** New module: `(web server http)', HTTP-over-TCP web server implementation See "Web" in the manual, for more information, but as a taste of things, try the following command line: meta/guile examples/web/debug-sxml.scm Then visit http://localhost:8080/ in your web browser. Let us know how it goes! ** Better Emacs Lisp implementation Brian Templeton's Summer-of-Code work was finally merged in, which should improve the state of Guile's Elisp support. There is still some work to do, so patches are welcome! ** R6RS fixes There were many fixes and enhancements to the R6RS support. Thanks to Julian Graham, Andreas Rottmann, and Göran Weinholt. ** Expression-oriented readline history Guile's readline history now tries to operate on expressions instead of input lines. Let us know what you think! ** Better syntax errors The Scheme expander, Ecmascript compiler, and other language implementations now produce more useful syntax errors. The default error handlers print them out more nicely now. ** Lots of documentation updates In particular, the documentation for GOOPS and regular expressions has seen some work. Unfortunately the code has come too fast and furious for full documentary folios, so some of the new modules are still undocumented. ** Better pretty-printing Indentation recognizes more special forms, like `syntax-case', and read macros like `quote' are printed better. ** Multicast socket options Support was added for the IP_MULTICAST_TTL and IP_MULTICAST_IF socket options. See "Network Sockets and Communication" in the manual, for more information. ** Deprecate `cuserid' `cuserid' has been deprecated, as it only returns 8 bytes of a user's login. Use `(passwd:name (getpwuid (geteuid)))' instead. ** New procedure `reload-module', and `,reload' REPL command See "Module System Reflection" and "Module Commands" in the manual, for more information. ** New `,in' REPL command See "Module Commands" in the manual, for more information. ** Allow user-defined REPL meta-commands This feature is not documented yet. See `define-meta-command' in `(system repl command)'. ** Add support for unbound fluids See `make-unbound-fluid', `fluid-unset!', and `fluid-bound?' in the manual. ** Add `variable-unset!' See "Variables" in the manual, for more details. ** New procedures: `compose', `negate', and `const' See "Higher-Order Functions" in the manual, for more information. ** Command line additions The guile binary now supports a new switch "-x", which can be used to extend the list of filename extensions tried when loading files (%load-extensions). ** And of course, the usual collection of bugfixes Interested users should see the ChangeLog for more information. You can follow Guile development in the Git repository and on the Guile mailing lists. Guile builds from the `master' branch of Git have version number 1.9.x. Guile versions with an odd middle number, e.g., 1.9.*, are unstable development versions. Even middle numbers indicate stable versions. This has been the case since the 1.3.* series. Please report bugs to `bug-gu...@gnu.org'. We also welcome reports of successful builds, which can be sent to the same email address. Ludovic Courtès, on behalf of the Guile team.
