return the quit args.
(scm-style-repl): call -quit, passing return value from
error-catching-repl. Make -quit return its args.
stand-along-repl: comment out, since it seems unused.
(top-repl): convert the value returned by scm-style-repl to
an integer and return it.
(error-catching-loop thunk): discard trailing junk after a (quit).
* r4rs.scm (apply, call-with-current-continuation): Added comment
explaining why apply and call/cc need to be closures.
* boot-9.scm (apply, call-with-current-continuation): Bugfix:
Removed. These definitions are already present in r4rs.scm.
it anyway because 1. it is very useful, and, 2. you can start
making it less premature by complaining to me and by modifying
the source! :-)
(trace): Given one or more procedure objects, trace each one.
Given no arguments, show all traced procedures.
(untrace): Given one or more procedure objects, untrace each one.
Given no arguments, untrace all traced procedures. The tracing in
Guile have an advantage to most other systems: We don't create new
procedure objects, but mark the procedure objects themselves.
This means that also anonymous and internal procedures can be
traced.
* boot-9.scm (error-catching-loop): Added handling of apply-frame
and exit-frame exceptions.
* * boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
(set-repl-prompt!): Setter for repl prompt.
(scm-style-repl): If prompt is #f, don't prompt; if prompt is a
string, display it; if prompt is a thunk, call it and display its
result; otherwise display "> ".
(Change suggested by Roland Orre <orre@nada.kth.se>.)
`module-defined?', since the module system isn't bootstrapped when
we load r4rs.scm. This is just a temporary fix to make the
repository version runnable.
recording of source code positions. This was placed there for our
convenience, but it has already sneaked into the distribution
once... so we'd better add this in our local copies instead when
we need it. (These options are normally enabled at the end of
boot-9.scm when loading the debug module.)
(macroexpand-1, macroexpand): Use local-ref instead of defined?
and eval.
* r4rs.scm (%load-verbosely): Use "module-defined?" instead of
"defined?".
* slib.scm (defined?): New function to take the place of the
builtin "defined?". It allways examines the slib module.
* boot-9.scm (split-c-module-name, convert-c-registered-modules,
init-dynamic-module, dynamic-maybe-call,
find-and-link-dynamic-module, link-dynamic-module,
try-module-dynamic-link, registered-modules): New definitions for
dynamic linking of modules.
(resolve-module): Try to dynamically link the requested module
after failing to load it as Scheme code.
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
* debug.scm: Enable debugging evaluator and recording of positions
by default.
