* Implemented new editor-based debugger, which uses the standard
debugger to generate its presentations (by means of new hooks in the
runtime system). The debugger can be invoked manually by the command
`browse-continuation', or automatically by setting one of the
following variables true:
debug-on-evaluation-error error during evaluation
debug-on-editor-error editor error (user error)
debug-on-internal-error editor bug
Normally `debug-on-evaluation-error' is true and the others are false.
* Controlification redone so that controlification of all ASCII
control characters is uniform. Previously characters such as newline
and page were handled specially. The net result of this is that
controlification of an ASCII control character has no effect.
* C-x C-c is now bound to a command which exits Scheme and returns to
the unix shell.
* All messages are cleared immediately after reading the first
character of a command key sequence. This is similar to the action of
GNU Emacs, and prevents non-temporary messages from sticking around
for a long time.
* Dired now handles symbolic links specially, showing the file linked
to in the usual way.
* Bug fix in `clear-message': this procedure now preserves the
command-prompt; previously it was clearing both the message and the
command-prompt.
* Bug fix in "cterm": the `move-cursor!' operation must move the
cursor immediately if an update is not in effect.
* Bug fix in `revert-buffer': can't assume that the buffer being
reverted is current.
* Bug fix: `with-output-to-string' had incorrect indentation method.
* Bug fix: typo in dired sorting routine.
Chris Hanson [Mon, 7 Aug 1989 07:37:09 +0000 (07:37 +0000)]
* Major rewrite of `debug' and `where' to allow their code to be used
as a presentation mechanism for the editor. The basic new design has
these features:
** All commands now accept a state argument, which they manipulate,
allowing the entire debugger state to be passed around easily.
** All output from the commands is wrapped by the procedure
`presentation', which can be grabbed to control the presentation
characteristics. For example, the editor uses this hook to clear the
debugger buffer, change current-output-port to go to that buffer, and
then reset the modified flag after the presentation is complete.
** "Failure" conditions generated by the debugger are signalled
through the new procedure `debugger-failure', which can be grabbed.
The editor grabs this and binds it to `editor-failure'.
** Advisory messages generated by the debugger are signalled through
the new procedure `debugger-message', which can be grabbed. The
editor grabs this and binds it to `editor-message'.
* The contracts for `prompt-for-confirmation?' and
`prompt-for-expression' have been changed to make them compatible with
the editor's versions of these procedures.
* The package loader no longer offers the "load interpreted?" option.
This is controlled by a flag which can be set should this option be
desired. Similarly, the cold-loader no longer offers this option --
in that case you must move or delete the ".com" files to get an
interpreted cold-load.
* A new operation `pretty-print' is similar to `pp' except that it
doesn't print a prefix newline and it does nothing special about hash
numbers or named structures.
