bdf8afffb5 * backtrace.c: Introduced exception handlers which now enclose 
`display-error' and `display-backtrace' so that error reporting
won't get into infinite loops if an error occurs during displaying
of the error.  This can very easily happen with user supplied
print call-back routines.

23f53cd3e2 * backtrace.c (scm_backtrace): Split message string across

compilers.
 1997-04-16 22:52:47 +00:00
Mikael Djurfeldt
78f9f47bb5 * snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL.

is an immediate.

e3c37929e0 * * backtrace.c (scm_display_application): New procedure: 
display-application; Set fancy printing parameters individually
	for different types of display (backtrace, error, application).
	(These should of course be customizable!)

Mikael Djurfeldt
5aab5d961c * symbols.c (scm_sysintern0): New function. Contains the core of 
old scm_sysintern but doesn't take a second value argument.
(scm_sysintern): Now uses scm_sysintern0.
(scm_sysintern_no_module_lookup): Renamed to
scm_sysintern0_no_module_lookup and doesn't take a second value
argument any longer.

* symbols.h (scm_sysintern0: Added declaration.

* options.c (scm_init_opts): Use scm_sysintern0 instead of
scm_sysintern when interning option keys.  Otherwise we risk
destroying the values of already interned variables.

* symbols.c (scm_sym2vcell): Bugfix: Treat definedp as
scheme-level boolean (use SCM_NFALSEP).

* backtrace.c (scm_init_backtrace): Make Scheme-level variable
`the-last-stack'.
(scm_backtrace): New function. (C version of old function from
boot-9.scm) Motivation: Make it possible to display backtraces
without depending on boot-9.scm.  (I'm uncertain if this
motivation is good enough...)

* root.h (scm_root_state): Add member the_last_stack_var.
(scm_the_stack_var): Defined to scm_root->the_last_stack_var.

* root.c (mark_root): Mark scm_the_last_stack_var.

* init.c (scm_start_stack): Initialize scm_the_last_stack_var to
SCM_BOOL_F.

Jim Blandy
f3acc5c15f * backtrace.c (scm_display_error_message): Made non-static, and

 1996-12-10 01:41:37 +00:00

841076acf4 * backtrace.c (scm_display_error): Just a safety measure: Stacks 
aren't created with zero length, but should such a strange
creature suddenly turn up...
 1996-10-17 23:32:47 +00:00
Mikael Djurfeldt
ab4f3efbfc * Makefile.in: Added entries for new files: backtrace.c,
