* *.c: Pervasive software-engineering-motivated rewrite of
function headers and argument checking. Switched SCM_PROC, SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names later, but was useful to keep old versions around while migrate) that has docstrings and argument lists embedded in the GUILE_PROC macro invocations that expand into a function header. Use lots of new SCM_VALIDATE_* macros to simplify error checking and reduce tons of redundancy. This is very similar to what I did for Scwm. Note that none of the extraction of the docstrings, nor software engineering checks of Scwm is yet added to Guile. I'll work on that tomorrow, I expect. * Makefile.am: Added scm_validate.h to modinclude_HEADERS. * chars.c: Added docstrings for the primitives defined in here. * snarf.h: Added GUILE_PROC, GUILE_PROC1. Added SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC still remains for now. Changed naming convention for the s_foo string name of the primitive to be s_scm_foo for ease of use with the macro. * scm_validate.h: Lots of new SCM_VALIDATE macros to simplify argument checking through guile. Maybe some of these should be folded into the header file for the types they check, but for now it was easiest to just stick them all in one place.
