* module/system/base/language.scm (current-language): Default to 'scheme
here, rather than relying on *current-language* always being bound.
Thanks to 亚光唐 <texnician@gmail.com> for the report.
* module/language/tree-il/primitives.scm (+, *, cons*): In the case of
just one argument (the identity case), expand to (values x) instead of
just x. Fixes values truncation in that case.
(values): Likewise remove (values x) -> x translation, as the compiler
will do it for us, and this fixes (values (values 1 2)).
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Handle
`values' in a push context here.
* test-suite/tests/tree-il.test ("values"): Add some tests.
http://savannah.gnu.org/bugs/?33362
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Rename
from flatten, as it really just takes a particular case. Instead of
iteratively compiling lambda cases through `comp', tail-call through
flatten-lambda-case. This allows code to see which case it's being
compiled in. Take advantage of that to limit the self-tail-call
optimization to self-calls to the same case -- otherwise we might be
jumping to a label without having reserved the right number of
locals.
(flatten-lambda): Adapt the caller.
* test-suite/tests/compiler.test ("case-lambda"): Add a test.
* module/ice-9/psyntax.scm (generate-temporaries): Give temporaries the
current module, so that they may be bound at the top level.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/Makefile.am:
* module/system/base/target.scm: Add a minimal module to parameterize
the target system type and inspect properties on it like cpu, vendor,
os, endianness, and word size.
* module/rnrs/io/ports.scm (open-file-input-port)
(open-file-output-port): Ensure the resulting ports are binary when no
transcoder is specified.
* test-suite/tests/r6rs-ports.test: Remove superfluous global change of
`%default-port-encoding' and accompanying comment.
("7.2.7 Input Ports"): Add test ensuring `open-file-input-port' opens
a binary port when no transcoder is specified.
("8.2.10 Output ports"): Strengthen existing `open-file-output-port'
binary-ness test by setting `%default-port-encoding' to "UTF-8".
...by not using its own-rolled getopt, and moving the `list' function
to a separate script
* meta/guile-tools.in: Use (ice-9 getopt-long).
(directory-files, strip-extensions, unique, find-submodules,
list-scripts): Deleted (and moved to new `list.scm' file).
(getopt): Deleted.
(main): Use getopt-long. Default to calling the `list' script if no
script is specified.
* module/scripts/list.scm: New script.
* module/Makefile.am (SCRIPTS_SOURCES): Add list.scm.
(For use by guile-tools)
* module/ice-9/getopt-long.scm: Use (ice-9 optargs) so we can use
define*.
(process-options): Add stop-at-first-non-option parameter. When
this is true, stop processing when we hit a non-option (so long as
that non-option isn't something that resulted from the unclumping of
a short option group).
(getopt-long): Add #:stop-at-first-non-option keyword; pass it on to
process-options.
* test-suite/tests/getopt-long.test ("stop-at-first-non-option"): New
test (for the above).
This is needed as a prerequisite for the following change that
introduces the stop-at-first-non-option option, because when that
option is used we don't know upfront how far through the command
line we should proceed with unclumping.
* module/ice-9/getopt-long.scm (expand-clumped-singles): Delete.
(process-options): Add a loop variable to indicate how many elements
at the start of `argument-ls' are known not to be clumped. When we
see a short option and this variable is <= 0, perform unclumping
(using code that used to be in expand-clumped-singles) and loop with
the variable > 0.
(getopt-long): Don't call expand-clumped-singles upfront here.
Basically, accumulate values in the `process-options' loop variables,
instead of using set-option-spec-value!
* module/ice-9/getopt-long.scm (option-spec): Delete the `value' slot.
(process-options): Delete `val!loop' and just use `loop' everywhere
instead. When adding an option spec to `found', add the
corresponding value too; hence `found' becomes an alist, where it
was previously a list of specs.
(getopt-long): Use assq-ref to get values out of `found'. Remove
unhittable error condition for detecting an option that requires an
explicit value, where a value wasn't supplied. This condition is
actually caught and handled in `process-options'. Rewrite the end
of the procedure much more simply.
* module/ice-9/futures.scm (%workers, %create-workers!)
(create-workers!): Define a mechanism to spawn off the future threads
only when the first future is created.
(make-future): Call create-workers! here.
* module/ice-9/boot-9.scm (define-module): Fix to load the #:use-module
clauses in the order in which they appear in the define-module form.
Thanks to Jan Nieuwenhuizen for the report.
* test-suite/standalone/test-import-order: Add new test that
define-module and use-modules resolve the interface in the right
order.
* test-suite/standalone/Makefile.am:
* test-suite/standalone/test-import-order-a.scm:
* test-suite/standalone/test-import-order-b.scm:
* test-suite/standalone/test-import-order-c.scm:
* test-suite/standalone/test-import-order-d.scm: Aux files.
* module/rnrs/io/ports.scm (open-file-output-port): Handle `no-fail'
file option.
(with-i/o-filename-conditions): Use `with-throw-handler' instead of `catch'.
(with-i/o-port-error,
with-textual-output-conditions. with-textual-input-conditions): New
exception-conversion helpers.
(put-char, put-datum, put-string, display): Use
`with-textual-output-conditions' instead of `with-i/o-encoding-error'
to get proper conditions in case of write errors.
(get-char, get-datum, get-line, get-string-all, lookahead-char):
Likewise, for the input case.
* test-suite/tests/r6rs-ports.test (pass-if-condition, test-file,
make-failing-port): New helpers.
("8.2.10 Output ports"): Add some tests for `open-file-output-port'.
("8.2.9 Textual Input"): Add tests read error conditions.
("8.2.12 Textual Output"): Add tests for write error conditions.
("8.3 Simple I/O"): Add tests for conditions, `call-with-input-file'
and `call-with-output-file'.
* module/ice-9/vlist.scm (vlist-fold-right): Avoid `vlist-reverse' and
instead `vlist-ref' individual elements. The result is about twice
faster. Thanks Andy for suggesting it indirectly. :-)
* module/language/glil/compile-assembly.scm: Clean up code for
subprograms (not needed, we just cache the glil) and object alists
(replaced by constants tables).
* module/language/glil/compile-assembly.scm (compile-assembly): Rework
to handle toplevel-specific code generation here, instead of in
glil->assembly. Specifically, here we build a global constant table,
and arrange for it to be the objtable of the toplevel thunk.
(compile-program): New helper, compiles a <glil-program> and returns
just the (load-program ...) form.
(compile-objtable): New helper, generates assembly to build an object
table, using some other constants table, and possibly recursing to
`compile-program' for cached GLIL programs.
(glil->assembly): Simplify, removing the toplevel? argument, and
replacing the object alist with an objtable computed in a previous
pass. Adapt to the new form of the objtable, and to use
compile-program and compile-objtable.
* module/language/glil/compile-assembly.scm (dump-constants): New
helper. Generates bytecode that will result in a vector for the
global object table being pushed on the stack. The items in the
global object table will share state as much as possible.
* module/language/glil/compile-assembly.scm (immediate?): New helper.
(build-constant-store): New helper. Walks the GLIL tree and builds up
a constant table, as a vhash.
(build-object-table): Another helper, builds a constant table for a
given GLIL program.
* module/rnrs/io/ports.scm (display): Implement as an
exception-converting wrapper around Guile's core display.
* module/rnrs/io/simple.scm: Don't export Guile's corresponding core
procedures, but use `(rnrs io ports)' instead. This way, we get the
conditions required by R6RS raised.
* doc/ref/r6rs.texi (rnrs io simple): Mention that these procedures are
supposed to raise R6RS conditions.
* module/srfi/srfi-1.scm (map-in-order): As we are not extending the
core `map' binding, actually make a new `map-in-order' alias here.
Fixes fresh builds.
* module/ice-9/boot-9.scm (map, for-each): Implement in Scheme instead
of C. There are boot versions before `cond' is defined.
(map-in-order): Define this alias here instead of in evalext.h.
* libguile/eval.c: Stub out the map and for-each definitions to just
call into Scheme.
* libguile/evalext.c: Remove map-in-order definition.
* module/srfi/srfi-1.scm: Replace all calls to map1 with calls to map.
(map, for-each): Define implementations here, in Scheme, instead of in
C.
* test-suite/tests/eval.test (exception:wrong-length, "map"): Update the
expected exception for mapping over lists of different lengths.
* libguile/srfi-1.h:
* libguile/srfi-1.c: Remove map and for-each definitions. Remove the
bit that extended the core `map' primitive with another method: the
right way to do that is with modules.
* libguile/srfi-1.c:
* libguile/srfi-1.h (scm_srfi1_member): Move implementation to Scheme.
* module/srfi/srfi-1.scm (member): Implement here, with the inlining
cases for eq? and eqv?. Speeds up a compiled bootstrap of
psyntax.scm, because lset-adjoin inlines to the memq case.
(lset<=): Reindent.
(lset-adjoin, lset-union): If the comparator is eq? or eqv?, just pass
it through to `member', so we inline to memq / memv. Use something
closer to the reference implementations.
* module/language/assembly/compile-bytecode.scm (compile-bytecode):
Rewrite to fill a bytevector directly, instead of using bytevector
ports. `write-bytecode' itself is still present and almost the same
as before; it's just that `write-byte' et al now inline the effect of
writing a byte to a binary port.
* test-suite/tests/asm-to-bytecode.test (comp-test): Refactor to use
public interfaces.
* module/language/assembly.scm (byte-length): Silly, minor tweak: put
the fixed-length instruction case first. Seems to shave some 10% off
the time compiling psyntax.scm (when the whole rest of the system is
compiled, of course).
* module/statprof.scm (statprof-reset): Make full-stacks? into an
optional arg instead of doing the rest arg dance.
(statprof-display): Format gc-time-taken appropriately.
* module/ice-9/r4rs.scm (call-with-input-file, call-with-output-file): Rewrite
with call-with-values.
(with-input-from-file): use call-with-input-file.
(with-output-to-file, with-error-to-file): use call-with-output-file.
Update docstrings to make clear that multiple values may be yielded.
* module/ice-9/boot-9.scm (while): Specify the return value as #f under
normal conditions, #t under (break), and arg... under (break arg...).
* test-suite/tests/syntax.test ("while"): Test.
* doc/ref/api-control.texi (while do): Document.
* module/ice-9/control.scm (reset, shift): Add implementations of these
operators from Wolfgang J Moeller, derived from implementations by
Oleg Kiselyov.
(reset*, shift*): Procedural variants.
* test-suite/tests/control.test ("shift and reset"): Add tests,
originally from Oleg Kiselyov.
