27 conversion functions follow the GUILE naming convention, i.e.
31 SCM ly_str02scm (char const*c);
32 SCM ly_deep_copy (SCM);
35 SCM ly_symbol2scm (char const *);
36 String ly_scm2string (SCM s);
37 String ly_symbol2string (SCM);
38 SCM ly_offset2scm (Offset);
39 Offset ly_scm2offset (SCM);
41 Interval ly_scm2interval (SCM);
42 SCM ly_interval2scm (Interval);
44 SCM ly_parse_scm (char const* s, int* n);
45 SCM ly_quote_scm (SCM s);
49 display and print newline.
51 void ly_display_scm (SCM s);
55 void read_lily_scm_file (String);
56 void init_lily_guile ();
61 these conversion functions also do a typecheck on the argument, and
62 return a default value if S has the wrong type.
