controls whether autoloading is attempted or not. Default is #t.
(process-define-module): Don't autoload the defined module.
(try-module-autoload): Don't autoload the directory modules.
* * boot-9.scm (process-define-module): Ensure that the-scm-module
is last in the `uses' list to allow shadowing builtin
bindings. All :use-module options are added in the order they
appear in the arguments but before anything already on the list
(such as the-scm-module).
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.
(OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
open-output-file, open-io-file, close-input-port,
close-output-port, close-io-port, call-with-input-file,

with-error-to-file, with-input-from-string, with-output-to-string,
with-error-to-string, the-eof-object): Definitions moved to
r4rs.scm. Not all of them are R4RS, but those that are use those
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.
%try-load itself was the primitive.
(load-with-path): use scm-error instead of %load-announce-lossage.
Errors are thrown to 'misc-error instead of 'could-not-load.
(%load-announce-lossage): deleted.
SCM-style errors. handle the case that an unexpected number
of args are supplied.
(%%system-errors): removed.
(error): redefine using a throw with key and 4 args.
('error): associate 'error, 'error-signal keys with
%%handle-system-error.
(%%default-error-handler): removed.
(signal-handler): throw with 4 args and use the error-signal key.
Create an error message instead of using numerical codes.
(%%bad-throw): call error instead of throw if key not found.
* boot-9.scm: initialize new error keys (see libguile/ChangeLog).
(%%handle-system-error key): check subr is not #f before printing.
Recognize %s (embed an argument using "display") and
%S (embed an argument using "write").
* error.c, error.h: setup scm_num_overflow key.
* __scm.h: SCM_NUM_OVERFLOW: macro for reporting numerical overflow.
Remove definition of SCM_OVSCM_FLOW.
* fports.c (scm_open_file): use SCM_SYSERROR_M.
* __scm.h: SCM_SYSERROR_M: new macro for system errors with an
explicit message and args.
* error.c, error.h, __scm.h: change system_error_sym to
scm_system_error.
* error.c (system_error_sym): remove leading %% from the Scheme name
"%%system-error".
* __scm.h (SCM_SYSMISSING): Redefine using lgh_error.
* boot-9.scm: remove leading %% from references to '%%system-error.
(%%handle-system-error): don't pass all the thrown arguments when
aborting, just the key and subr.
Remove the code to "Install default handlers for built-in errors."
Remove the definition of the syserror procedure.
Associate 'numerical-overflow with default handler.
resolved-ref --> nested-ref Motivation: conformance to the other
dictionary operators: list-ref operates on list, vector-ref
operates on vector, nested-ref operates on nested namespace,
local-ref operates on the local nested namespace.
(implementation-vicinity, parse-path): Deleted, along with code to
initialize %load-path.
* boot-9.scm (in-vicinity): If the vicinity doesn't end with a
"/", use one to separate it from the file.
Add the directory named after the version number.
Prepend the version number to the other directories in the path.
Simplify by mapping the common prefix onto each item.
* Makefile.in (datadir, pkgdatadir, pkgverdatadir, subpkgdatadir,
sitedatadir): New definitions.
(libparent, libdir, install_path): Replaced by above.
(install): Create the above directories.
Put the source files into subpkgdatadir.
(uninstall): Remove the above directories.
