* libguile/backtrace.c (scm_print_exception): Add C binding for
print-exception, which dispatches to whatever is defined in Scheme.
(boot_print_exception): Add initial binding, replaced later in
Scheme.
* module/ice-9/boot-9.scm: Expect there to already be a print-exception
binding.
* module/system/repl/error-handling.scm (error-string): Just use
print-exception instead of rolling our own printer.
(call-with-error-handling): Simplify.
* module/ice-9/boot-9.scm (set-exception-printer!, print-exception):
Define an extensible exception-printing mechanism.
Also register printers for all keys thrown by Guile.
Inspired by a patch by Andreas Rottmann.
* libguile/frames.c (scm_frame_source): Don't call out to (system vm
frames), as this routine is used when printing exceptions. Make
available in the default environment (ugh).
* module/system/vm/frame.scm: Remove frame-source definition and
export.
* libguile.h:
* libguile/Makefile.am:
* libguile/deprecated.h:
* libguile/deprecated.c:
* libguile/init.c:
* libguile/properties.c:
* libguile/properties.h: Deprecate the "primitive properties"
interface. It was only used to implement object properties, and that
is no longer the case.
* module/ice-9/boot-9.scm (make-object-property): Reimplement just in
terms of weak hash tables, and make threadsafe.
* NEWS:
* doc/ref/api-utility.texi: Update.
* module/ice-9/getopt-long.scm (fatal-error): New helper. For errors
that come from the user -- i.e., not the grammar -- we will handle our
own error printing and call `exit' rather than relying on the root
catch handler. This is more friendly to the user than a Scheme
backtrace.
(parse-option-spec, process-options, getopt-long): Call `fatal-error'
as appropriate.
* test-suite/tests/getopt-long.test (pass-if-fatal-exception): New
helper, checks that a certain key was thrown to, and that suitable
output has been printed on an error port.
(deferr): Change to expect a 'quit key instead of 'misc-error. Update
exceptions to not match the beginning of the string, as that will be
the program name. Update tests to use pass-if-fatal-exception.
* module/ice-9/getopt-long.scm: #:keywords in the define-module block.
(option-spec): Define as a srfi-9 record instead of playing macro
games with boot-9 records.
* module/ice-9/format.scm (format): When DESTINATION is #f, use a
Unicode-capable output string port.
* test-suite/tests/format.test ("format basic output")["default to
Unicode-capable port"]: New test.
* module/system/repl/error-handling.scm (display-syntax-error)
(error-string): Until we get the exception-printing patch merged in,
copy display-syntax-error into error-handling so that we avoid
display-error. Fixes bug 32365.
* module/ice-9/psyntax.scm (quasiquote): Import new definition from
upstream psyntax, to allow unquote and unquote-splicing to take
multiple arguments.
(unquote, unquote-splicing): Adapt to not require a particular syntax
form.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/tree-il/inline.scm (boolean-value): Add a case for
applications of primitives, and move the memq/memv->bool code here.
(inline!): We were inlining (memq 'a '(a b c)) => #t, and not the list
tail, which was an embarrassing bug. Fixed by moving this code to the
boolean-value function. Thanks to Mark Harig for the report.
* module/rnrs/io/ports.scm (&i/o-encoding): New error condition type.
(with-i/o-encoding-error): New macro.
(put-char, put-datum, put-string): Use it.
* test-suite/tests/r6rs-ports.test ("8.2.6 Input and output
ports")["transcoded-port, output [error handling mode = raise]"]: New
test.
* module/rnrs/io/ports.scm (&i/o-decoding): New error condition type.
(with-i/o-decoding-error): New macro.
(get-char, get-datum, get-line, get-string-all, lookahead-char): Use
it.
* test-suite/tests/r6rs-ports.test ("8.2.6 Input and output
ports")["transcoded-port [error handling mode = raise]"]: Use `guard'
and `i/o-decoding-error?'.
* module/system/repl/command.scm (warranty, copying, version): Use
`define-meta-command' to define these procedures, so they are entered
into the *command-infos* table.
* module/ice-9/psyntax.scm (chi-top): When adding to the toplevel
environment at compile-time, default to undefined variables, not
variables defined to #f.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/boot-9.scm (module-add!): Add a new pre-modules version
of this function, so we can add variables the environment, not just
values.
(module-define!): Use module-add!.
* libguile/numbers.c (scm_euclidean_quo_and_rem, scm_euclidean_quotient,
scm_euclidean_remainder, scm_centered_quo_and_rem,
scm_centered_quotient, scm_centered_remainder): New extensible
procedures `euclidean/', `euclidean-quotient', `euclidean-remainder',
`centered/', `centered-quotient', `centered-remainder'.
* libguile/numbers.h: Add function prototypes.
* module/rnrs/base.scm: Remove incorrect stub implementations of `div',
`mod', `div-and-mod', `div0', `mod0', and `div0-and-mod0'. Instead do
renaming imports of `euclidean-quotient', `euclidean-remainder',
`euclidean/', `centered-quotient', `centered-remainder', and
`centered/', which are equivalent to the R6RS operators.
* module/rnrs/arithmetic/fixnums.scm (fxdiv, fxmod, fxdiv-and-mod,
fxdiv0, fxmod0, fxdiv0-and-mod0): Remove redundant checks for division
by zero and unnecessary complexity.
(fx+/carry): Remove unneeded calls to `inexact->exact'.
* module/rnrs/arithmetic/flonums.scm (fldiv, flmod, fldiv-and-mod,
fldiv0, flmod0, fldiv0-and-mod0): Remove redundant checks for division
by zero and unnecessary complexity. Remove unneeded calls to
`inexact->exact' and `exact->inexact'
* test-suite/tests/numbers.test: (test-eqv?): New internal predicate for
comparing numerical outputs with expected values.
Add extensive test code for `euclidean/', `euclidean-quotient',
`euclidean-remainder', `centered/', `centered-quotient',
`centered-remainder'.
* test-suite/tests/r6rs-arithmetic-fixnums.test: Fix some broken test
cases, and remove `unresolved' test markers for `fxdiv', `fxmod',
`fxdiv-and-mod', `fxdiv0', `fxmod0', and `fxdiv0-and-mod0'.
* test-suite/tests/r6rs-arithmetic-flonums.test: Remove `unresolved'
test markers for `fldiv', `flmod', `fldiv-and-mod', `fldiv0',
`flmod0', and `fldiv0-and-mod0'.
* doc/ref/api-data.texi (Arithmetic): Document `euclidean/',
`euclidean-quotient', `euclidean-remainder', `centered/',
`centered-quotient', and `centered-remainder'.
(Operations on Integer Values): Add cross-references to `euclidean/'
et al, from `quotient', `remainder', and `modulo'.
* doc/ref/r6rs.texi (rnrs base): Improve documentation for `div', `mod',
`div-and-mod', `div0', `mod0', and `div0-and-mod0'. Add
cross-references to `euclidean/' et al.
* NEWS: Add NEWS entry.
* module/oop/goops/compile.scm (compute-cmethod): Fix a bug
that caused the method compiler to barf while compiling a
method that calls (next-method), if there is no applicable
next method.
* module/rnrs/base.scm (real-valued?, rational-valued?,
integer-valued?): Implement in compliance with R6RS.
* test-suite/tests/r6rs-base.test: Add test cases for
`real-valued?', `rational-valued?', and `integer-valued?'.
* NEWS: Add NEWS entries.
* libguile/numbers.c (scm_finite_p): Add new predicate `finite?' from
R6RS to guile core, which returns #t if and only if its argument is
neither infinite nor a NaN. Note that this is not the same as (not
(inf? x)) or (not (infinite? x)), since NaNs are neither finite nor
infinite.
* test-suite/tests/numbers.test: Add test cases for `finite?'.
* module/rnrs/base.scm: Import `inf?' as `infinite?' instead of
reimplementing it. Previously, the R6RS implementation of
`infinite?' did not detect non-real complex infinities, nor did it
throw exceptions for non-numbers. (Note that NaNs _are_ considered
numbers by scheme, despite their name).
Import `finite?' instead of reimplementing it. Previously, the R6RS
implementation of `finite?' returned #t for both NaNs and non-real
complex infinities, in violation of R6RS.
* NEWS: Add NEWS entries, and reorganize existing numerics-related
entries together under one subheading.
* doc/ref/api-data.texi (Real and Rational Numbers): Add docs for
`finite?' and scm_finite_p.
* module/ice-9/format.scm (format): Test to make sure an argument is a
number before applying `inf?' and `nan?' to it. Formerly, format
would call `inf?' and `nan?' on arguments that might be either a
number or a string, although those predicates should ideally throw an
exception when applied to non-number objects.
This is so that compiling the same code on environments with different
locale settings yields the same result.
* module/system/base/compile.scm (compile-file): When ENC if #f, default
to "UTF-8" instead of `(fluid-ref %default-port-encoding)'.
* doc/ref/api-evaluation.texi (Compilation): Document the default output
file name and default source file encoding for `compile-file' and
`guile-tools compile'.
* module/language/tree-il/fix-letrec.scm: Replace U+2019 with an ASCII
quote. The iconv implementation on FreeBSD would immediately notice
and bail out when reading it under a US-ASCII locale.
* module/web/request.scm (build-request): Make URI a positional
argument.
* module/web/response.scm: Remove extend-response.
(read-response): Fix a docstring.
* module/web/server.scm (extend-response): Include extend-response here,
but not exported.
