expand-primitives! change, and rename from optimize!.
* module/language/tree-il/compile-glil.scm:
* module/system/repl/common.scm:
* test-suite/tests/cse.test:
* test-suite/tests/peval.test:
* test-suite/tests/tree-il.test: Adapt to expand-primitives and optimize
changes.
* module/system/repl/common.scm: Add not only 2013, but also 2012 to the
copyright notice at the top of the file, since the file was changed in
2012.
(*version*): Bump copyright year to 2013 in REPL greeting.
* module/system/repl/common.scm (make-repl): Fix to accept language
objects in addition to symbols. Fixes http://debbugs.gnu.org/9857.
Thanks to Tristan Colgate for the report.
* module/system/repl/command.scm:
* module/system/repl/debug.scm (terminal-width): Move terminal-width
here, make it thread-local, and export it.
(print-locals, print-frame, print-frames): Default width to
terminal-width.
* module/system/repl/error-handling.scm (call-with-error-handling): Add
`report' and `backtrace' on-error handlers.
* module/system/repl/common.scm (repl-default-options): Add on-error
REPL option, defaulting to `debug', but which may be changed.
* module/system/repl/repl.scm (run-repl): Pass the #:on-error REPL
option to call-with-error-handling.
Fixes bug in repl meta-commands after activating readline, which changes
the current input port.
* module/system/repl/common.scm (<repl>): Remove inport and outport
fields.
(make-repl): Adapt.
(repl-read, repl-print): Just read and write to the current ports.
* module/system/repl/repl.scm (meta-reader): Meta-read from the current
input port.
* module/system/repl/command.scm (read-command, define-meta-command):
Read from the current input port.
* 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/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/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/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*.
* 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.
* libguile/vm.h (struct scm_vm): Remove "time" and "clock" members. The
time was bogusly measured, and the "clock" measured instructions
retired, which is not a very useful measurement, and it was causing
lots of memory accesses. Not that I have done a proper profile,
though...
(scm_vm_stats): Remove this procedure, which provided access to "time"
and "clock".
* libguile/vm.c:
* libguile/vm-engine.h:
* libguile/vm-engine.c:
* libguile/vm-i-system.c: Adapt to scm_vm changes and scm_vm_stats
removal.
* module/system/repl/command.scm:
* module/system/vm/vm.scm: Adapt to vm-stats removal by removing
vm-stats from <repl>.
* module/ice-9/boot-9.scm (make-fresh-user-module): New public function,
makes an anonymous beautified module.
* module/language/objcode/spec.scm: We used to have some things in here
that allowed lexical variable names and values to be a part of the
environment, but no more. Now an environment is just a module. If you
want to "inject" free variables into code, just use lambda.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Same
here. Also, rely on the fact that an environment *will* be a module --
because (system base compile) guarantees that for us.
* module/language/scheme/spec.scm (scheme): In the reader, rely on the
environment being a module. Define a #:make-default-environment
handler, which returns a beautified module, augmented with a fresh
definition for current-reader, so that side effects to current-reader
are restricted to the compilation unit.
* module/language/tree-il/analyze.scm
(report-possibly-unbound-variables):
* module/language/tree-il/compile-glil.scm (compile-glil):
* module/language/tree-il/optimize.scm (optimize!): The environment will
be a module.
* module/system/base/language.scm (<language>): New field,
`make-default-environment'. Defaults to `make-fresh-user-module'.
(default-environment): New accessor, returns a default environment for
a language.
* module/system/repl/common.scm (repl-compile): Always compile relative
to the current module, because a module is always acceptable as an
environment.
* module/system/base/compile.scm (compile-file, compile-and-load): Both
of these have a new keyword argument, #:env. For `compile-file', it
defaults to the default environment of the source language, and for
`compile-and-load', to the current module.
(read-and-compile): If there are no expressions read, pass the joiner
its default environment (via `default-environment joint').
* module/language/assembly/spec.scm:
* module/language/brainfuck/spec.scm:
* module/language/bytecode/spec.scm:
* module/language/ecmascript/spec.scm:
* module/language/glil/spec.scm:
* module/language/scheme/spec.scm:
* module/language/tree-il/spec.scm: Language-readers now take two
arguments: the port and the environment. This should allow for
compile-environment-specific reader behavior.
* module/system/base/compile.scm (read-and-compile):
* module/system/repl/common.scm (repl-read): Pass the environment to the
language-reader.
* module/system/repl/repl.scm (meta-reader, prompting-meta-read):
* module/system/repl/command.scm (define-meta-command): Use the second
argument to repl-reader, so we avoid frobbing current-reader.
* module/system/base/compile.scm (make-compilation-module,
language-default-environment): New procedures.
(read-and-compile, compile): Have ENV default to
`(language-default-environment from)'.
(compile-and-load): Compile in `(current-module)'.
* module/system/repl/common.scm (repl-compile): Explicitly compile in
the current module so that macro definitions are visible.
* libguile/load.c (kw_env): New variable.
(do_try_autocompile): Call `compile-file' with `#:env (current-module)'.
* test-suite/tests/compiler.test ("psyntax")["compile uses a fresh module by
default", "compile-time definitions are isolated"]: New tests.
["compile in current module"]: Specify `#:env (current-module)'.
["redefinition"]: Adjust.
* test-suite/tests/bytevectors.test (c&e): Explicitly compile in the
current module so that its imports are visible.
* module/system/repl/command.scm:
* module/system/repl/common.scm:
* module/system/repl/repl.scm:
* module/system/vm/debug.scm:
* module/system/vm/trace.scm: Change #:use-syntax to #:use-module, as
that's really what we want to do.
* module/system/base/syntax.scm (define-record): So, in the generated
constructors, allow optional arguments, but not keyword arguments.
Conses much less in the constructors.
(define-record/keywords): And the old define-record is here.
* module/language/ghil.scm (parse-ghil):
* module/language/ghil/compile-glil.scm (codegen):
* module/language/scheme/compile-ghil.scm (translate-1, quote)
(quasiquote): Don't use keywords in this compiler hotpath.
* module/system/base/language.scm (<language>):
* module/system/repl/common.scm (<repl>):
* module/system/vm/debug.scm (<debugger>): Use define-record/keywords.
