Embeddable Common-Lisp / News: Recent posts

Windows application

Michael Goffioul has updated his sample text editor. It now uses ECL's dynamic FFI to access the Windows API and can run either compiled or interpreted. Furthermore, by embedding Scintilla's component (http://www.scintilla.org), the editor can perform syntax highlighting of Lisp code.

A screenshot is here:

Dynamic FFI

ECL's unstable version (in CVS) now contains means both to call C functions and to export functions to the C world (callbacks). Furthermore, this project, initiated by M. Goffioul, has led to an implementation that, at least on the Intel platform, does not rely on the C compiler, but on assembler code generated run time. We hope to port this to the remaining architectures: PPC, Sparc, x86_64

If you want to test it, save the code below in a file called "example.lsp" and load it in the interpreter (if on x86/Windows,Linux,FreeBSD) or compile it and load it (if on other platforms).... read more

ECL 0.9g

It's been long since version 0.9f and a lot of improvements and fixes have accumulated, so it's quite a good time for a new release. As already mentioned in the newsgroups, this release is significantly faster due to optimizations in the SUBTYPEP routine, plus some minor fixes in the compiler.

As side news worth mentioning, SLIME has been ported to ECL and work is going on slowly but steadily on making the compiler more stable and efficient.... read more

Wiki for ECL

A Wiki has been set up for the ECL project, and it is now linked to in all webpages. The address is http://ecls.sourceforge.net/cgi-bin/view

Although the Wiki was set up long ago, not being very proficient with this kind of tools I preferred waiting until the stability of the setup was confirmed.

Right now the Wiki contains little but very useful data:

  • Links to the manuals
  • The FAQ, a rapidly growing document
  • A documentation of the multiprocessing capabilities in ECL.... read more

More on OSX

I have updated my laptop with OSX Tiger and in the process discovered that gcc 4.0 does not like ECL. Well, this is not a big issue, since ECL still compiles with the older gcc 3.3 which is shipped with XCode and which produces binaries that can be run on OSX 10.3. The installation instructions have been updated to reflect this fact (http://ecls.sourceforge.net/install.html#osx)

Incidentally, the newest version of perl shipped with Tiger breaks the texi2html script and is not able to process ECL's documentation. Also this has been fixed in the CVS version.... read more

Win32 bridge

Michael Goffioul has contributed a library for calling Microsoft Windows's GUI functions from ECL. The library uses ECL's own implementation of the UFFI (Unified Foreign Function Interface) and demonstrates that this is really usable. As examples, he has written both the typical button example and a small, single window text editor. You can find a screenshot at the project homepage (https://sourceforge.net/project/screenshots.php?group_id=30035)

News on OSX port

I just bought a tiny 12" iBook and compiled ECL on it. It seems that there were two problems in the latest release:

(i) The fixes on the linux platform to avoid name clashes, caused some problem on OSX.

(ii) Most important is the fact that the 10.3 seems to include a flaky (at least not good enough for ECL) dlfcn.h header, which caused ECL not to use the OSX standard functions for loading FASL files.... read more
