This is the next pre-release of what will eventually become the 2.0 release series. 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-devel@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, 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=20C 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-1.9.2.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 2.64 Automake 1.11 Libtool 2.2.6 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 1.9.1 pre-release: ** VM speed improvements Closures now copy the free variables that they need into a flat vector instead of capturing all heap-allocated variables. This speeds up access to free variables, avoids unnecessary garbage retention, and allows all variables to be allocated on the stack. Variables which are `set!' are now allocated on the stack, but in "boxes". This allows a more uniform local variable allocation discipline, and allows faster access to these variables. The VM has new special-case operations, `add1' and `sub1'. ** VM robustness improvements The maximum number of live local variables has been increased from 256 to 65535. The default VM stack size is 64 kilo-words, up from 16 kilo-words. This allows more programs to execute in the default stack space. In the future we will probably implement extensible stacks via overflow handlers. Some lingering cases in which the VM could perform unaligned accesses have been fixed. The address range for relative jumps has been expanded from 16-bit addresses to 19-bit addresses via 8-byte alignment of jump targets. This will probably change to a 24-bit byte-addressable strategy before Guile 2.0. ** Compiler optimizations Procedures bound by `letrec' are no longer allocated on the heap, subject to a few constraints. In many cases, procedures bound by `letrec' and `let' can be rendered inline to their parent function, with loop detection for mutually tail-recursive procedures. Unreferenced variables are now optimized away. ** Compiler robustness Guile may now warn about unused lexically-bound variables. Pass `-Wunused-variable' to `guile-tools compile', or `#:warnings (unused-variable)' within the #:opts argument to the `compile' procedure from `(system base compile)'. ** Incomplete support for Unicode characters and strings Preliminary support for Unicode has landed. Characters may be entered in octal format via e.g. `#\454', or created via (integer->char 300). A hex external representation will probably be introduced at some point. Internally, strings are now represented either in the `latin-1' encoding, one byte per character, or in UTF-32, with four bytes per character. Strings manage their own allocation, switching if needed. Currently no locale conversion is performed. Extended characters may be written in a string using the hexadecimal escapes `\xXX', `\uXXXX', or `\UXXXXXX', for 8-bit, 16-bit, or 24-bit codepoints, respectively. This support is obviously incomplete. Many C functions have not yet been updated to deal with the new representations. Users are advised to wait for the next release for more serious use of Unicode strings. ** `defined?' may accept a module as its second argument Previously it only accepted internal structures from the evaluator. ** `let-values' is now implemented with a hygienic macro This could have implications discussed below in the NEWS entry titled, "Lexical bindings introduced by hygienic macros may not be referenced by nonhygienic macros". ** Global variables `scm_charnames' and `scm_charnums' are removed These variables contained the names of control characters and were used when writing characters. While these were global, they were never intended to be public API. They have been replaced with private functions. ** EBCDIC support is removed There was an EBCDIC compile flag that altered some of the character processing. It appeared that full EBCDIC support was never completed and was unmaintained. ** Packaging changes Guile now provides `guile-2.0.pc' (used by pkg-config) instead of `guile-1.8.pc'. ** 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-guile@gnu.org'. We also welcome reports of successful builds, which can be sent to the same email address.
