Hi all,
I want to implement docstrings for my extension functions, but for various
reasons I can't use snarfing (the array it generates has problems with C++
namespaces).
So I had a look through the macros for SCM_DEFINE to find out what it does
with the DOCSTRING argument, and got lost pretty quickly, so I tried
running the example through the C preprocessor, and it seems the docstring
is lost anyway:
static const char s_clear_image [] = "clear-image"; SCM clear_image (SCM
image_smob)
{
}
void
init_image_type ()
{
# 1 "clear-image.x" 1
scm_c_define_gsubr (s_clear_image, 1, 0, 0, (SCM (*)()) clear_image); ;
# 14 "clear-image.c" 2
}
after snarfing and cpping the example code:
#include <libguile.h>
SCM_DEFINE (clear_image, "clear-image", 1, 0, 0,
(SCM image_smob),
"Clear the image.")
{
/* C code to clear the image in image_smob... */
}
void
init_image_type ()
{
#include "clear-image.x"
}
Any pointers to what happens with the docstring, or how I can implement
them for my functions?
Many thanks,
dave
