I've just checked in a new version of riaxpander with initial support for compiling syntax extensions.
Previously, any file containing macros that you wanted to export you would mark as (syntax) in the .setup file, and just install the file as a .scm without compiling it. Now, when using riaxpander, you have the option of compiling the file with the -Dcompile-syntax option and it works the same way (for all macros, including syntax-rules, explicit-renaming, etc.). There's an example in the wiki documentation. The compiled syntax can only be currently used only with riaxpander (though I'm considering adding support so that it can be loaded from the syntactic-closures egg as well). Because of this, you probably don't want to make published eggs compiled, since it removes the option of using alternate macro systems. It can be useful for private code, though. The effect of this is to speed load-time, and for complex macros speed expansion (compile) time. It won't make any resulting code any faster, it just speeds up the development process. It's also essential if you want to distribute proprietary macro code, and is the first step towards a proper module system. Even if you don't compile any syntax yourself, users of riaxpander will notice a huge difference in that riaxpander now loads *instantly* (because it of course compiles all its own syntax), whereas all the other hygienic macro systems take forever and a day to load. -- Alex _______________________________________________ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
