We are delighted to announce GNU Guile release 2.2.7, the seventh
bug-fix release of the “legacy” 2.2 series (the current stable series is
3.0). See the NEWS excerpt that follows for full details.
* * *
Guile is an implementation of the Scheme programming language.
The Guile web page is located at https://gnu.org/software/guile/, and
among other things, it contains a copy of the Guile manual and pointers
to more resources.
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.
Guile implements many common Scheme standards, including R5RS, R6RS, and
a number of SRFIs. In addition, Guile includes its own module system,
full access to POSIX system calls, networking support, multiple threads,
dynamic linking, a foreign function call interface, and powerful string
processing.
Guile 2.2.7 can be installed in parallel with Guile 3.0.x; see
https://www.gnu.org/software/guile/manual/html_node/Parallel-Installations.html.
* * *
Changes in 2.2.7 (since 2.2.6)
* New interfaces and functionality
** (texinfo plain-text) now exports '*line-width*' fluid
The new '*line-width*' fluid allows users to specify the width of a line
for the purposes of line wrapping. See "texinfo plain-text" in the
manual.
* Bug fixes
** Reduce GC pressure when using bignums
Guile no longer installs a finalizer on each bignum (large integer) it
creates. This significantly improves speed and memory usage on
applications that make heavy use of bignums, such as the compiler
itself.
** Fix peval bug that ignored excess arguments
In an expression like:
((lambda ()
(define (add1 n)(+ 1 n))
(add1 1 2)))
the compiler (specifically 'peval') would silently ignore the excess
argument to 'add1'.
** Respect thread local fluid defaults
Previously (fluid-ref (make-thread-local-fluid #t)) would return #f.
This is now fixed.
** Fix non-deterministic crash in 'finalization_thread_proc'
(<https://bugs.gnu.org/37757>)
** texinfo properly renders @acronym in plain text
(<https://bugs.gnu.org/37846>)
** 'scm_port_poll' honors "w" flags
(<https://bugs.gnu.org/36709>)
** Do not record LDFLAGS in .pc file
(<https://bugs.gnu.org/36339>)
** Fix Readline configure check for the sake of libedit
This fixes builds on macOS against the system-provided libedit.
** Fix build on platforms where the stack grows upwards

[*] 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 guile-2.2.7.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 pool.sks-keyservers.net \
--recv-keys 3CE464558A84FDC69DB40CFB090B11993D9AEBB5
and rerun the 'gpg --verify' command.
This release was bootstrapped with the following tools:
Autoconf 2.69
Automake 1.16.1
Libtool 2.4.6
Makeinfo 6.7
Gnulib v0.1-1157-gb03f418
Happy hacking with Guile!
