[resend to guile-user, first copy went to bug-guile] Hi, All,
For use from a Fortran program I am collecting API fixes for libguile.so as wrapper functions for what is provided to C-programs as macros. I noted that some of the macros are function-macros some are symbol macros. An example of the latter is #define scm_to_int scm_to_int23 This is inconsistent and makes escaping such macros slightly more difficult. (Honestly I dont know a way yet). One guile developer on IRC said this is "probably a good thing to fix" so I report it here. I dont build Guile 2 myself as the installations I use are quite dated/conservative. As a background, Fortran allows you to declare "foreign" functions, for example, like this: type, public, bind(c) :: scm_t private integer(c_intptr_t) :: do_not_ever_use end type scm_t interface function scm_symbol_p (obj) result (yes) bind (c) type(scm_t), intent(in), value :: obj type(scm_t) :: yes end function scm_symbol_p ... end interface This makes use of library functions quite handy. But it does not provide a way to access a C-macro, naturally. Alexei #include <libguile.h> SCM guile_macro_scm_from_int (int i); int guile_macro_scm_to_int (SCM obj); int (scm_is_true) (SCM obj); int (scm_is_symbol) (SCM obj); int (scm_is_null) (SCM obj); SCM (scm_eol) (void); SCM guile_macro_scm_from_int (int i) { return scm_from_int(i); } int guile_macro_scm_to_int (SCM obj) { return scm_to_int(obj); } int (scm_is_true) (SCM obj) { return scm_is_true(obj); } int (scm_is_symbol) (SCM obj) { return scm_is_symbol(obj); } int (scm_is_null) (SCM obj) { return scm_is_null(obj); } SCM (scm_eol) () { return SCM_EOL; }
