aren't enabled by default any longer (they are switched on in
debug.scm). But during development we want to have them also
*inside* boot-9.scm. Therefore, two lines are added at the
beginning of boot-9.scm to enable these.
should see as little clutter as possible.
* r4rs.scm (%load-verbosely): Make this #f by default.
* boot-9.scm (scm-repl-verbose): Make this #f by default.
(scm-style-repl): Don't run 'pk' on the value passed to quit.
* r4rs.scm: New file.
* boot-9.scm: Load r4rs.scm, first thing.

that are not.
(load, %load-verbosely, %load-announce): Moved, along with code to
set %load-hook, to r4rs.scm.

* boot-9.scm (integer?): Definition deleted, in favor of the one
present in libguile (which used to be called int?). I have no
idea why integer? didn't just call int? to begin with.
* boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
=?, >?, and >=? deleted; they're defined that way by libguile now.
after-error-hook, before-backtrace-hook and after-backtrace-hook
to the error handler. E.g.: fancy emacs support could plug into
these.
(save-stack): New function. The stack is now made differently
depending on the stack id. (The motivation is to make a better
choice regarding what stack frames to present to the user.)
(error-catching-loop): Stack handling code moved outside into
save-stack.
error-catching-loop.
Don't set 'throw-handler-default property on error keys.
Just interpret (almost) any throw with 4 args as an error throw.
Delete some try-load stuff that was already commented out.
handle-system-error): Backtracing now works for signals aswell;
Backtracing mechanism can now identify the stack root created by
start-stack so that the user isn't exposed to system stack frames.
throw-handler-default.
((handle-system-error key . arg-list)): Changed the way errors are
reported.
((scm-style-repl)): Wrap up the call to eval in a start-stack
acro.
((error-catching-loop thunk)): Introduce a lazy-catch into
error-catching-loop so that the stack can be captured.
make-vector fill new vectors with '(); this will make it easier to
port Guile Scheme code to other Schemes.
* boot-9.scm (make-print-style, make-print-table): Same.
Append "." to the default %load-path.
(feature?): new function: checks for a symbol in the features list.
(module-local-variable): remove apparently useless (caddr (list m v
...))
(%load-announce): minor formatting change.
(file-exists?): use access? if posix is featured.
(file-is-directory?): use stat if i/o-extensions is featured.
(try-module-autoload module-name): use file-exists? before
file-is-directory?
to 'misc-error instead of 'error (no need to distinguish these.)
Don't set up 'error as a key.
Set up regex-error as a key, if regex is available.
(signal-handler): use scm-error, not throw.
(%try-load, try-load-with-path, %load, load-with-path,
basic-try-load-with-path, basic-load-with-path,
try-load-module-with-path,load-module-with-path): deleted, since
they seem redundant.
(try-load): define using %try-load, not try-load-with-path.
(load): rewritten. load tries to open the file directly and
with a .scm extension before searching the library directories
(should "." be added to %load-path? then load could still open
directly files starting with "/").
(try-module-autoload): use load, not load-with-path.
(%load-indent): deleted, -2 was causing errors.
(%read-sharp): use port-line, not line-number.
