Gauche is an R7RS Scheme implementation developed to be a handy script interpreter, which allows programmers and system administrators to write small to large scripts for their daily chores. Quick startup, built-in system interface, native multilingual support are some of my goals.

Gauche runs on several Unix-like platforms.

Gauche - minor bug fixes

Several bug fixes since, plus a couple of improvements. I made a new package since one bug caused build problems in certain settings, and having a fixed tarball saved lots of troubles.

  • Bug fixes:
    • If DESTDIR was set and the platform didn't have previous Gauche installed, make install failed saying something like "libgauche-0.9.so.0.3: cannot open shared object file: No such file or directory". The order of installation was adjusted to avoid it.
    • On FreeBSD, a bug in signal setup routine caused memory corruption.
    • every with more than one argument list didn't return the last return value of the predicate when all the arguments satisfied it, as specified in srfi-1 (it returned #t instead). It was also the case in stream-every. Both are fixed.
    • On MinGW, info command didn't work.
    • On MinGW, when you used non-console version gosh-noconsole.exe and tried to spawn a child process to communicate via pipes, gosh-noconsole.exe just died.
  • Improvements:
    • New procedure: string-scan-right
    • GC is now 7.2b
