What's new in CLISP 2.49

Jul 8, 2010
  • User visible changes:
  • New command line option -disable-readline lets working around bugs and incompatibilities between readline CLISP was built against and the library actually installed. See for details.
  • FFI:OPEN-FOREIGN-LIBRARY now accepts the :REQUIRE argument. See for details.
  • New user variable CUSTOM:*USER-LIB-DIRECTORY* is respected by REQUIRE and used by "clisp-link install". Dynamic modules are now the default build option. See and for details.
  • Function RENAME-FILE now accepts :IF-EXISTS argument which determines the action when the destination exists, unless, of course, *ANSI* is T. See for details.
  • The replacement value entered by the user in STORE-VALUE and USE-VALUE restarts is now EVALuated.
  • The old user variable CUSTOM:*PRINT-CLOSURE* now controls interpreted closure output too (RFE#3001956). This is a tricky feature, read up! See .
  • Module readline now supports readline 6.1. (Older versions are, of course, still supported). See for details.
  • Module pcre now supports pcre 8.01. (Older versions are, of course, still supported). See for details.
  • Module libsvm does not come with the upstream sources anymore, install locally and pass --with-libsvm-prefix to the top-level configure instead. All upstream versions up to 2.91 are supported. See for details.
  • Module berkeley-db now supports Berkeley-DB 4.8. (Older versions are, of course, still supported). See for details.
  • Module postgresql now supports PostgreSQL 8.4. (Older versions are, of course, still supported). See for details.
  • Module pari has been updated to support both 64 & 32 bit platforms with and without GMP. See for details.
  • New functions OS:VERSION-COMPARE et al call strverscmp. See for details.
  • Bug fixes:
  • Do not eliminate function calls which are advertised to have exceptional situation in unsafe code (bug#2868166).
  • Fix an internal error in DECLAIM on bad OPTIMIZE quality (bug#2868147).

  • Handle TWO-WAY-STREAM and ECHO-STREAM correctly by (SETF STREAM-EXTERNAL-FORMAT) (bug#3020933).
  • Fix unbuffered output pipe stream initialization (bug#3024887).
  • ANSI compliance:
  • Implement the ANSI issue COMPILER-DIAGNOSTICS:USE-HANDLER: use the CL Condition System for compiler diagnostics.

New in CLISP 2.47 (Oct 24, 2008)

  • New module DBUS interfaces to the D-Bus message bus system.
