* module/system/repl/repl.scm (run-repl): Run the thunk in a stack in a
prompt, similar to the default prompt. Gives proper backtraces.
* module/system/repl/error-handling.scm (call-with-error-handling):
Narrow one more outer frame, for the %start-stack thunk invocation.
* module/ice-9/boot-9.scm (%start-stack): Reindent.
* module/system/repl/common.scm: Use (ice-9 history). Turns on value
history by default.
(repl-default-options): Expand the format of options to include an
optional value transformer, run when setting a value. Add prompt and
value-history options.
(repl-prepare-eval-thunk): Use repl-option-ref.
(repl-option-ref): Error if the option is unknown.
(repl-option-set!, repl-default-option-set!): Error if the option is
unknown. Pass the val through the transformer procedure.
(repl-default-prompt-set!): Just use repl-default-option-set!.
* module/system/repl/command.scm (option): Update for the new options
format.
* module/system/repl/common.scm (repl-default-options): Heap-allocate
the repl-default-options, to avoid mutating a literal.
(make-repl): Copy repl-default-options.
* module/system/repl/repl.scm (abort-on-error): New helper.
(run-repl): Don't enter the debugger during parsing or compilation of
a repl expression. If you want to debug compilation, run compilation
from the repl, not as part of the repl.
* module/system/repl/debug.scm (print-locals): Run the before-print-hook
on the values, so we can hook into (ice-9 history) if available. Don't
bother printing binding indices. Give a little per-line-prefix.
* module/system/repl/command.scm (read-command): Remove a pk.
* module/system/repl/repl.scm (run-repl): Export. Use % and abort to
implement the prompt.
* module/system/repl/debug.scm: New file, defines a data type to hold
state for a debugger stack, and some helper procedures to print the
stack or print a frame. Most pieces are from (system vm debug).
* module/system/repl/error-handling.scm: New file, implements
call-with-error-handling and with-error-handling, and instead of going
into a debugger, we go into a recursive repl that happens to have
debugging information. Will be removing the old debugger from (system
vm debug) shortly.
* module/Makefile.am (SYSTEM_SOURCES): Add error-handling and debug scm
files.
* module/system/repl/repl.scm (prompting-meta-read): Better error
handling -- we don't want to go into a debugger when reading a
command.
(start-repl): Add #:debug keyword argument, and just dispatch to
run-repl.
(run-repl): New function, with the guts of the old start-repl. Added a
prompt, to which a throw to 'quit will abort.
* module/system/repl/common.scm (repl-prepare-eval-thunk): New
helper. In the future we will use this to not enter the debugger on
errors that happen at compile time.
(repl-eval): Use repl-prepare-eval-thunk.
(repl-print): Run the before-print-hook when printing a value.
* module/system/repl/command.scm (*command-table*): Move `option' to the
`system' group. Move `trace' to the `profile' group. Add `debug' and
`inspect' groups.
(command-abbrevs): Rename from command-abbrev, and allow multiple
abbreviations.
(display-group): Fix the case where abbrev? was #f.
(display-summary): Fix alignment of the command and
abbreviations. Allow multiple abbreviations.
(read-command): Rename from read-datum, and have better error
handling.
(meta-command): Better error handling.
(define-meta-command): Better error handling.
(help, show, import, compile, disassemble, time, profile, trace): Fix
docstrings and error messages.
(define-stack-command): New helper, for commands that operate on a
saved stack.
(backtrace, up, down, frame, procedure, locals): New debugger
commands, in the REPL now.
(inspect, pretty-print): New "inspect" commands.
* module/ice-9/boot-9.scm (*repl-stack*): Instead of repl-level, have a
stack.
(batch-mode?): Change to poke the stack.
* module/ice-9/deprecated.scm (set-batch-mode?!): Update deprecation
method.
* module/system/repl/common.scm (repl-prompt): Update to poke
*repl-stack* to get the level.
* module/system/repl/repl.scm (start-repl): Bind *repl-stack*
appropriately.
* module/system/repl/common.scm (<repl>): Add inport and outport fields
and accessors.
(make-repl): Add optional "debug" argument. Bind inport and outport to
the current inport and output ports at the time of repl creation.
(repl-read): Read from the repl inport.
(repl-print): Write to the repl outport.
* module/system/repl/command.scm (read-datum, read-line, meta-command):
Respect repl-inport, and bind the outport of meta-commands to the repl
outport.
* module/ice-9/boot-9.scm (*repl-level*): New global fluid, moved here
from (system repl common).
(batch-mode?): Reimplement in terms of *repl-level*.
(ensure-batch-mode!): A replacement for set-batch-mode?!.
* module/ice-9/deprecated.scm (set-batch-mode?!): Deprecate.
* module/ice-9/popen.scm (open-process): Use ensure-batch-mode!.
* module/ice-9/scm-style-repl.scm (error-catching-loop): Override
ensure-batch-mode!.
* module/system/repl/common.scm: Remove *repl-level*.
* module/system/repl/common.scm (repl-default-option-set!): New
interface.
(repl-default-prompt-set!): New procedure, sets the 'prompt property
in the default env.
(repl-prompt): Use the 'prompt repl option if available.
* module/system/repl/repl.scm (start-repl): If the debugging ports are
unbound, bind them to the current i/o ports. Allows errors within
with-output-to-foo / with-input-from-foo to be sensibly debugged.
* module/system/repl/repl.scm (prompting-meta-read): Use
call-with-error-handling.
* module/system/vm/debug.scm (call-with-error-handling): Add case for
#:on-error 'pass. Have the catch handler return the unspecified value.
* module/system/repl/repl.scm (prompting-meta-read): Catch and print
read errors here, returning unspecified in that case.
(start-repl): Don't enable the debugger while reading expressions.
Adapt with-backtrace to with-error-handling.
* module/system/vm/debug.scm (run-debugger, debugger-repl): No need to
take a stack, the frames vector is sufficient.
(call-with-error-handling, with-error-handling): New public utilities.
Notably they do not poke the-last-stack.
* module/system/vm/debug.scm (frame->module): Actually bind frame-local
variables to values in the new anonymous module. Setting settable vars
should work too :)
* module/system/repl/common.scm (*repl-level*): New public fluid.
(repl-prompt): If *repl-level* is a positive integer, add it to the
prompt.
* module/system/repl/repl.scm (start-repl): The `lang' argument is now
optional, and defaults to (current-language). New kwargs level and
welcome; level defaults to 0, or 1+ the existing level, and the
welcome is a boolean, true if level is 0. Parameterize *repl-level*
during the dynamic extent of this repl. Also, parameterize
the-last-stack to #f for the duration of this repl.
* module/system/vm/debug.scm (frame->module, debugger-repl): Stubs of a
recursive repl implementation. The idea is to be a repl in the lexical
context of the error; but it would be nice to be able to operate in
the module of the proc too, for example to export bindings. Hmm.
* module/system/base/compile.scm:
* module/system/base/language.scm (*current-language*, current-language):
Move this fluid and thunk down to (system base language).
* module/system/base/language.scm (<language>): Remove the `version'
field from languages. It just wasn't useful.
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:
* module/language/elisp/spec.scm:
* module/language/glil/spec.scm:
* module/language/objcode/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm:
* module/language/value/spec.scm: Remove #:version from all language
definitions. Shorten some language names (e.g. "Guile Scheme" ->
"Scheme").
* module/system/base/compile.scm (compile-file, compile-and-load): Add a
keyword arg #:canonicalization, which defaults to 'relative. In this
way, one might compile "../module/ice-9/boot-9.scm", but the path that
gets residualized into the .go is "ice-9/boot-9.scm".
* libguile/programs.h:
* libguile/programs.c (scm_program_name): Remove. procedure-name is
sufficient.
* module/system/vm/program.scm (program-name): Remove from exports list.
(program-documentation): Remove; procedure-documentation is
sufficient.
* libguile/debug.c (scm_procedure_name): Remove special case for
programs.
* module/language/tree-il/analyze.scm (validate-arity): Use
procedure-name.
* module/ice-9/documentation.scm (object-documentation): Just use
procedure-documentation, without special cases for programs.
* libguile/programs.h:
* libguile/programs.c (scm_i_program_properties): Make internal.
(scm_program_name): Use scm_i_program_properties.
* libguile/procprop.c (scm_procedure_properties): Use
scm_i_program_properties, for programs.
* libguile/procs.c (scm_procedure_documentation): Use procedure-property
to get to 'documentation, not program-property.
* module/system/vm/program.scm (program-properties, program-property):
Remove from the exports list.
(program-documentation): Use procedure-property.
* module/texinfo/reflection.scm (macro-arguments)
(macro-additional-stexi)
(object-stexi-documentation): Use procedure-property, not
program-property.
* module/system/vm/debug.scm (*debug-input-port*):
(*debug-output-port*): New public fluids.
(run-debugger): Add some kwargs for input and output ports, defaulting
to the debug input and output ports.
(debug-pre-unwind-handler): Print to debug output port.
(debug): Untabify.
* module/system/repl/command.scm: Add support for ,show with topics
"warranty", "copying", and "version".
(language): Don't re-print the welcome; print sometime more terse.
* module/system/repl/common.scm (*version*, *warranty*, *copying*): New
public globals.
(repl-welcome): Display *version*.
* libguile/foreign.c (sym_null, null_pointer): New variables.
(scm_foreign_to_bytevector): Raise an error when PTR is NULL.
(scm_init_foreign): Define SYM_NULL.
* module/system/foreign.scm (%null-pointer): New exported binding.
* libguile/Makefile.am (lib_LTLIBRARIES): Instead of just "libguile.la",
make "libguile-@EFFECTIVE_VERSION@.la". This allows multiple versions
of Guile to be installed at once. See
http://www106.pair.com/rhp/parallel.html for a rationale.
(libguile_@GUILE_EFFECTIVE_VERSION@_la_CFLAGS):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):

(libguile_@GUILE_EFFECTIVE_VERSION@_la_DEPENDENCIES):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD):
(libguile_@GUILE_EFFECTIVE_VERSION@_la_LDFLAGS): Fixup automake vars
to include the effective version.
(guile_LDADD): Fix up the spelling of libguile.
* libguile/bytevectors.c (scm_bootstrap_bytevectors):
* libguile/foreign.c (scm_register_foreign):
* libguile/i18n.c (scm_bootstrap_i18n):
* libguile/instructions.c (scm_bootstrap_instructions):
* libguile/objcodes.c (scm_bootstrap_objcodes):
* libguile/programs.c (scm_bootstrap_programs):
* libguile/vm.c (scm_bootstrap_vm): Register extensions using e.g.
"libguile-2.0" as the libname -- i.e., including the effective version
in the libname.
* module/ice-9/i18n.scm:
* module/rnrs/bytevector.scm:

* module/system/foreign.scm:
* module/system/vm/instruction.scm:
* module/system/vm/objcode.scm:
* module/system/vm/program.scm:
* module/system/vm/vm.scm: When doing a load-extension for something in
Guile, use the effective version also.
* meta/guile-2.0-uninstalled.pc.in (Libs):
* meta/guile-2.0.pc.in (Libs): Use -lguile-@EFFECTIVE_VERSION@. This
change should mean that code built against Guile should not be
affected by the libguile rename.
* guile-readline/Makefile.am (libguilereadline_v_@LIBGUILEREADLINE_MAJOR@_la_LIBADD):
* srfi/Makefile.am
(libguile_srfi_srfi_1_v_@LIBGUILE_SRFI_SRFI_1_MAJOR@_la_LIBADD):

* module/ice-9/boot-9.scm (top-repl): Map (debug) at the repl to (system
vm debug).
* module/system/vm/debug.scm (run-debugger, debugger-repl): Don't take
the index as an arg, for now anyway.
(debug): New wrapper.
* libguile/stacks.c (scm_sys_stacks): New global variable, moved here
from boot-9.scm.
(scm_init_stacks): Define scm_sys_stacks to %stacks.
(stack_depth): Remove narrowing by frame pointer.
(find_prompt): New helper.
(narrow_stack): Clean up a bit, and allow narrowing by prompt tag.
(scm_make_stack): Update docs, and use scm_stack_id to get the stack
id.
(scm_stack_id): The current stack id may be fetched as the cdar of
%stacks.
(stack_id_with_fp): Remove helper.
* module/ice-9/boot-9.scm (%start-stack): Fix indentation.
(%stacks): Remove definition, it's in stacks.c now.
(default-pre-unwind-handler): Narrow by another frame.
(save-stack): Remove special handling for certain stack ids, as it is
often possible that the function isn't on the stack -- in the
interpreter, or after a tail call. Better to narrow by prompt ids.
* module/system/vm/debug.scm (print-frames): Change to operate on a
vector of frames.
(run-debugger): Change to receive a vector of frames. The debugger
also has the full stack, so it can re-narrow (or widen) to get the
whole stack, if the user wants.
(stack->vector): New helper.
(debug-pre-unwind-handler): Narrow by more frames, and to the most
recent start-stack invocation. Adapt to run-debugger change.
* module/system/repl/common.scm (<repl>): Remove "vm" field and repl-vm
accessor. I think the correct model is to just use the-vm. This change
was prompted by the need to have the REPL itself not cause a recursive
VM invocation, so that captured prompts at the REPL are rewindable.
(make-repl): Remove treatment of #:vm.
(repl-eval): Load a compiled expression as a simple thunk, avoiding a
recursive VM call.
* module/system/repl/command.scm (profile, trace): Remove repl-vm
treatment.
(backtrace, debugger, step): Remove, as they were not implemented.
* module/ice-9/control.scm (%): Add a single-argument case, which
instates a default prompt with a default handler.
* libguile/script.c (scm_compile_shell_switches): Wrap user programs in
a default prompt.
* module/system/repl/common.scm (repl-eval): REPL expressions are user
programs too; wrap each one in a default prompt.
* module/system/base/compile.scm (compiled-file-name): Add a comment.
* module/ice-9/boot-9.scm (load): Avoid loading up (system base compile)
just to compute an autocompiled file name. Fixes the issue whereby
guile-tools snarf-check-and-output-texi was inadvertantly loading up
srfi-1, and thereby a stale library, just to see if guile-tools itself
had a compiled version.
Not sure what the right unit test is here, other than vigilance.
