* doc/guile.1: Remove reference to the version and date. Mention R5RS,
instead of R4RS. Explicitly say that the full documentation is in
Texinfo (as other GNU packages do).
When you use GDS to evaluate Scheme code from Emacs, you can now use
`C-u' to indicate that you want to single step through that code. See
`Evaluating Scheme Code' in the manual for more details.
* scheme-using.texi (Evaluating Scheme Code): Document use of
`C-u' prefix with evaluation commands.
* gds-scheme.el (gds-eval-region, gds-eval-expression)
(gds-eval-defun, gds-eval-last-sexp): Support `C-u' prefix,
meaning that user wants to single step through the code.
* gds-client.scm (handle-nondebug-protocol): Add support for
setting a trap on code that is about to be evaluated.
* debugger/commands.scm (evaluate, info-args, info-frame,
position, up, down): Improve/fix doc strings.
* Makefile.am (SUBDIRS): Add debugging.
(ice9_sources): Add gds-client.scm and gds-server.scm.
* scheme-debugging.texi: Remove lots of text that is now
duplicated (exactly) elsewhere, leaving only the `Tracing' node.
* guile.texi: Replace `Debugging Features' (scheme-debugging.texi)
by `Using Guile Interactively' and `Using Guile in Emacs'
(scheme-using.texi). Move the `Tracing' content of
scheme-debugging.texi to the Modules section.
* api-options.texi (Evaluator trap options): Move doc for
with-traps and debug-object? to here.
* api-modules.texi (Included Guile Modules): Change reference from
`Debugging Features' to `Tracing'.
* api-evaluation.texi (Evaluator Behaviour): Add reference to
`Evaluator trap options'.
* api-debug.texi (Examining the Stack): Minor improvements to
display-backtrace doc.
* api-debug.texi (Debug on Error): New text on how to catch errors
and the error stack.
* api-debug.texi (High Level Traps): New.
* api-debug.texi (Debugging): New intro text. New subsection
"Evaluation Model". Moved existing subsections "Capturing the
Stack or Innermost Stack Frame", "Examining the Stack", "Examining
Stack Frames", "Source Properties", "Decoding Memoized Source
Expressions" and "Starting a New Stack" under "Evaluation Model".
(Capturing the Stack or Innermost Stack Frame): Some new text, and
correction to doc for last-stack-frame.
(Debug on Error): Renamed from "Interactive Debugging".
* configure.in (AC_CONFIG_FILES): Add emacs/Makefile and
ice-9/debugging/Makefile.
* Makefile.am (SUBDIRS): Add emacs.
* scheme-using.texi: New (merged with modifications from CVS
HEAD).
* Makefile.am, gds-scheme.el, gds-server.el, gds.el: New (merged
with modifications from CVS HEAD).
* debugging/Makefile.am, debugging/example-fns.scm,
debugging/ice-9-debugger-extensions.scm, debugging/steps.scm,
debugging/trace.scm, debugging/traps.scm, debugging/trc.scm: New
(merged with modifications from CVS HEAD).
* gds-client.scm, gds-server.scm: New (merged with modifications
from CVS HEAD).
