All *_p functions ought to accept anything without throwing an error.
Even if it doesn't seem to make sense. That way, I know I don't have
to validate before calling a validation routine. :-}
Anyway, *real bugs* in Guile 1.7.2 are:
1. When an error is thrown, "exit" should be called with EXIT_FAILURE, not 0.
2. After these commands:
(use-modules (ice-9 stack-catch))
(debug-enable 'backtrace)
I should be getting stack traces on Scheme errors. I'm not.
(And, yes, I invoke either ``(backtrace)'' or ``scm_backtrace()''
when a failure is detected.)
3. Either of these two implementations:
port = scm_open_input_string( AG_SCM_STR02SCM( pzExpr ));
#if GUILE_VERSION < 107000
{
static SCM file = SCM_UNDEFINED;
static char* pzFl = NULL;
scm_t_port* pt;
if ( (pzFl == NULL)
|| (strcmp( AG_SCM_CHARS( file ), pzFile ) != 0) ) {
if (pzFl != NULL)
free(pzFl);
pzFl = strdup( pzFile );
file = AG_SCM_STR02SCM( pzFile );
}
pt = SCM_PTAB_ENTRY(port);
pt->line_number = line - 1;
pt->file_name = file;
}
#else
{
static SCM file = SCM_UNDEFINED;
static char* pzOldFile = NULL;
if ((pzOldFile == NULL) || (strcmp( pzOldFile, pzFile ) != 0)) {
if (pzOldFile != NULL)
free( pzOldFile );
pzOldFile = strdup( pzFile );
file = scm_from_locale_string( pzFile );
}
scm_set_port_filename_x( port, file );
}
{
SCM ln = scm_from_int( line );
scm_set_port_line_x( port, ln );
}
#endif
should be enabling file and line numbers in errors. I've tried both methods
with 1.7 (and some others suggested in the discussion), to no avail. I can
get file and line information for 1.6.7 and earlier *only*. There seems to
be no way to do it in 1.7.
Thanks for your help! Regards, Bruce
