Release 0.9.6

Major feature upgrade

Notable feature enhancement:

Static linking and standalone executable support: Now you can create a standalone executable from Gauche program. See blog entry and "Building standalone executables" section.

Single shell-script installer (blog entry).

REPL enhancement: Pretty printing (blog entry), online document display (blog entry) and search (blog entry).

Method dispatch optimizations (1, 2).

Procedure inlining optimizations (1, 2)

Windows console Japanese handling: Thanks to @hamayama, numerous fixes to use Japanese on Windows command prompt is incorporated.

Bump to Boehm gc 7.6.6, thanks to @qykth-git.

Support mbedTLS as an additional TLS support, thanks to @qykth-git. See rfc.tls for the details.

for the details. format finally supports floating number formatting ~f . It also supports a subtle rounding mode switch regarding binary to decimal conversion (blog post).

finally supports floating number formatting . It also supports a subtle rounding mode switch regarding binary to decimal conversion (blog post). Support of using multiple versions of Gauche in parallel---from 0.9.6 and after, you can invoke a different version of Gauche by gosh -vVERSION , as far as VERSION of Gauche is also installed. This isn't much useful now ( VERSION must be 0.9.6 or later), but will be handy with future releases.

New modules and procedures

R7RS-Large Red Edition support (WiLiKi:Gauche:R7RS-RedEdition)

12 libraries (out of 17) are supported:

Those are still accessible as srfi-* names, but new code is recommended to use the scheme.* names.

Incompatible changes

Some change undocumented behaviors; others change because of bug fix.

Literal character sets ( #[chars] ) are now immutable, as other literal objects; it will raise an error if you try to mutate it.

) are now immutable, as other literal objects; it will raise an error if you try to mutate it. getter-with-setter now associates the setter to the getter in immutable way ('locked'); it will raise an error if you try to change it. It is the way specified in srfi-17. It also allows Gauche to inline setters. (NB: Many predefined setters are now locked. If your existing code alters them it will cause an error.)

(NB: Many predefined setters are now locked. If your existing code alters them it will cause an error.) list* , cons* - Requires at least one arg, as specified in srfi-1. Zero argument doesn't make sense, although previous versions of Gauche allowed it.

We've tolerated it before, but it's rather error prone. util.match : The way to match record instance with positional variables are changed for more reasonable way. We hope no code depends on the previous way, which was broken anyway. See the blog entry for the details.

See the blog entry for the details. twos-complement-factor : We fix the behavior when 0 is passed; it used to return 0, now it returns -1. The latter is consistent with srfi-60. Unfortunately we documented the former behavior, so it breaks compatibility.

Unfortunately we documented the former behavior, so it breaks compatibility. string-split : Splitting an empty string now yields an empty list instead of (""), as srfi-152 specifies

Other bug fixes

There are too many; we list up some notable ones.

The behavior of guard when no clauses are satisfied and the exception is reraised is now R7RS-compatible ( https://github.com/shirok/Gauche/pull/335 ). When using R7RS, with-exception-handler is R7RS compatible (which is slightly different from built-in with-exception-handler , compatible to srfi-18).
