* libguile/srcprop.h: Remove internal scm_source_whash declaration.
* libguile/srcprop.c (scm_i_set_source_properties_x)
(scm_i_has_source_properties): New helpers.
(scm_source_whash): Make static.
* libguile/read.c (scm_read_sexp): Remove register declarations here;
let's trust the compiler. Remove code to incrementally build up a
copy; instead let's let scm_i_set_source_properties_x handle copying
the expression if needed.
(scm_read_quote, scm_read_syntax): Use scm_i_set_source_properties_x.
(recsexpr): Remove this helper from 1996.
(scm_read_sharp_extension): Instead of trying to recursively label
sharp-read subforms with source properties, just label the outside
form and rely on the macro-expander to propagate it down.
* libguile/numbers.c (scm_logand): Fix a type error (comparing a SCM
against an int, when we really wanted to compare the unpacked
fixnum).
* libguile/ports.c (scm_i_set_conversion_strategy_x): Check
scm_conversion_strategy_init, not scm_conversion_strategy.
* libguile/read.c (recsexpr): Fix loops to avoid strange test of SCM
values.
* libguile/tags.h (SCM_MAKE_ITAG8_BITS): New helper, produces a
scm_t_bits instead of a SCM, because SCM_UNPACK is not a constant
expression with SCM_DEBUG_TYPING_STRICTNESS==2.
(SCM_MAKIFLAG_BITS): Remove SCM_MAKIFLAG, and replace with this, which
returns bits.
(SCM_BOOL_F_BITS, SCM_ELISP_NIL_BITS, SCM_EOL_BITS, SCM_BOOL_T_BITS):
(SCM_UNSPECIFIED_BITS, SCM_UNDEFINED_BITS, SCM_EOF_VAL_BITS):
(SCM_UNBOUND_BITS): New definitions. Defined SCM_BOOL_F, etc in terms
of them.
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_0):
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_1):
(SCM_XXX_ANOTHER_BOOLEAN_DONT_USE_2):
(SCM_XXX_ANOTHER_LISP_FALSE_DONT_USE): Be bits instead of SCM values.
(SCM_BITS_DIFFER_IN_EXACTLY_ONE_BIT_POSITION):
(SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS): Rename from
SCM_VALUES_DIFFER_..., and take unpacked bits as the args.
* libguile/boolean.c: Update verify block to use
SCM_BITS_DIFFER_IN_EXACTLY_TWO_BIT_POSITIONS et al.
* libguile/debug.c (scm_debug_opts):
* libguile/print.c (scm_print_opts):
* libguile/read.c (scm_read_opts): Use iflags bits for initializers.
* libguile/hash.c (scm_hasher): Use _BITS for iflags as case labels.
* libguile/pairs.c: Nil/null compile-time check uses
SCM_ELISP_NIL_BITS.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_whash_get_handle, SCM_WHASHFOUNDP)
(SCM_WHASHREF, SCM_WHASHSET, scm_whash_create_handle)
(scm_whash_lookup, scm_whash_insert): Deprecate this API.
* libguile/srcprop.c:
* libguile/srcprop.h:
* libguile/read.c (scm_read_sexp): Use the hashq API instead of the
whash API.
* libguile/read.c (scm_read_extended_symbol): Interpret '\' as an escape
character. Due to some historical oddities we have to support '\'
before any character, but since we never emitted '\' in front of
"normal" characters like 'x' we can interpret "\x..;" to be an R6RS
hex escape.
* test-suite/tests/reader.test ("#{}#"): Add tests.
* libguile/read.c (scm_read_sharp): Move the "#c..." case outside of
#if SCM_ENABLE_DEPRECATED, and to the same section which handles
"#s...", "#u..." and "#f...".
Thanks to Andreas Rottmann <a.rottmann@gmx.at> for the bug report.
* libguile/read.c (scm_i_scan_for_encoding): Fix for coding on first
line #! and for !# immediately following the coding.
* test-suite/Makefile.am:
* test-suite/tests/coding.test: Add tests.
* libguile/read.c (scm_i_scan_for_encoding): If possible, just use the
read buffer for the encoding scan, and avoid seeking. Fixes
`(open-input-file "/dev/urandom")', because /dev/urandom can't be
seeked backwards.
* libguile/read.c (scm_read_scsh_block_comment): Use `scm_getc' instead
of `scm_get_byte_or_eof'.
* test-suite/tests/reader.test ("read-options")["position of SCSH block
comment"]: New test.
* libguile/read.c (scm_read_opts): Default "positions" to #t. The
compiler was already turning it on anyway, and this allows
primitive-load without --auto-compile to also propagate source
information through the expander, for better errors and to let macros
know their source.
* module/language/scheme/spec.scm: No need to enable positions here
now.
* libguile/private-options.h (SCM_HUNGRY_EOL_ESCAPES_P): New private
option.
* libguile/read.c: Define SCM_HUNGRY_EOL_ESCAPES_P, defaulting to #f.
(skip_intraline_whitespace): New helper.
(scm_read_string): If SCM_HUNGRY_EOL_ESCAPES_P,
skip_intraline_whitespace after an escaped EOL.
* test-suite/tests/reader.test ("read-options"): Add test.
* libguile/bytevectors.c:
* libguile/eval.c:
* libguile/goops.c:
* libguile/i18n.c:
* libguile/load.c:
* libguile/memoize.c:
* libguile/modules.c:
* libguile/ports.c:
* libguile/print.c:
* libguile/procs.c:
* libguile/programs.c:
* libguile/read.c:
* libguile/script.c:
* libguile/srfi-14.c:
* libguile/stacks.c:
* libguile/strings.c:
* libguile/throw.c:
* libguile/vm.c: Use scm_from_latin1_symboln to make symbols from string
literals, because they aren't in the user's locale -- they are in
ASCII, and we can optimize this case.
* libguile/vm-i-loader.c: Also use scm_from_latin1_symboln when loading
narrow symbols.
* libguile/bytevectors.c:
* libguile/goops.c:
* libguile/instructions.c:
* libguile/numbers.c:
* libguile/random.c:
* libguile/read.c:
* libguile/vm-i-scheme.c: Fix a number of assumptions that a long could
hold an inum. This is not the case on platforms whose void* is larger
than their long.
* libguile/numbers.c (scm_i_inum2big): New helper, only implemented for
sizeof(void*) == sizeof(long); produces a compile error on other
platforms. Basically gmp doesn't have a nice interface for converting
between mpz values and intmax_t.
* libguile/debug.c:
* libguile/eval.c:
* libguile/frames.c:
* libguile/objcodes.c:
* libguile/print.c:
* libguile/programs.c:
* libguile/read.c:
* libguile/struct.c:
* libguile/vm.c: Fix a number of instances in which we assumed we could
fit a pointer into a long.
This allows customizing the reader behavior for a dynamic extent more easily.
* libguile/read.c (scm_read_hash_procedures): Renamed to
`scm_i_read_hash_procedures'.
(scm_i_read_hash_procedures_ref, scm_i_read_hash_procedures_set_x):
New (internal) accessor functions for the fluid.
(scm_read_hash_extend, scm_get_hash_procedure): Use these accessor
functions.
(scm_init_read): Create the fluid, named `%read-hash-procedures' instead of
the previous plain list `read-hash-procedures'.
* test-suite/tests/reader.test: Adapt the "R6RS/SRFI-30 block comment
syntax overridden" test to make use of the fluid.
* module/ice-9/deprecated.scm (read-hash-procedures):
New identifier macro -- backward-compatibility shim.
Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* libguile/private-options.h (SCM_ELISP_VECTORS_P, SCM_ESCAPED_PARENS_P):
* libguile/read.c (scm_read_opts): Remove unused elisp-vectors option,
and the elisp-strings option (which allowed \( and \) escapes in
strings).
(scm_read_string): Remove the elisp-strings case.
* doc/ref/api-options.texi (Reader options): Update, and update wording
of the case-insensitive bit.
R6RS character hex escapes do not conflict with legacy Guile octal
character escapes, so they can be enabled by default.
* libguile/read.c (scm_read_character): modified
* test-suite/tests/reader.test: modify character escape tests
* doc/ref/api-data.texi: modified
* doc/ref/api-options.texi: modified
Note especially that the variable 'i' has two different uses in this
function, and they get confused.
* libguile/read.c (scm_i_scan_for_encoding): cleanup
* libguile/read.c (scm_read_shebang): New function;
(scm_read_sharp): Call scm_read_shebang on '!', which delegates to
scm_read_scsh_block_comment as necessary.
* test-suite/tests/reader.test ("R6RS lexeme comment", "partial R6RS
lexeme comment"): New tests.
* libguile/read.c (read_token): now takes a C buffer instead of a SCM.
string. All callers changed.
(read_complete_token): now takes C buffers, not SCM strings. No longer
does port position updates or encoding processing. All callers changed.
(scm_read_number, scm_read_mixed_case_symbol, scm_read_number_and_radix)
(scm_read_character): Do port updates and string processing no longer
done by read_complete_token. Some reordering for optimization.
* libguile/private-options.h:
* libguile/read.c (scm_read_opts, SCM_SQUARE_BRACKETS_P): Add an option
for treating [ and ] as parentheses, on by default. Note that this
makes them delimiters also, so [ and ] cannot appear in a symbol name,
with this read option on.
(scm_read_sexp): If we start with [, we end with ].
(scm_read_expression): Add case for [.
When the reader option 'r6rs-hex-escapes is enabled, the \uNNNN and
\UNNNNNN string escape sequences should be disabled.
* libguile/read.c (scm_read_string): added checks for SCM_R6RS_ESCAPES_P
This adds a reader option 'r6rs-hex-escapes that modifies the
behavior of numeric escapes in characters and strings. When enabled,
variable-length character hex escapes (#\xNNN) are allowed and become
the default output format for numerically-escaped characters. Also,
string hex escapes switch to a semicolon terminated hex escape (\xNNNN;).
* libguile/print.c (PRINT_CHAR_ESCAPE): new macro
(iprin1): use new macro PRINT_CHAR_ESCAPE
* libguile/private-options.h (SCM_R6RS_ESCAPES_P): new #define
* libguile/read.c (scm_read_opts): add new option r6rs-hex-escapes
(SCM_READ_HEX_ESCAPE): modify to take a terminator parameter
(scm_read_string): parse R6RS hex string escapes
(scm_read_character): parse R6RS hex character escapes
* test-suite/tests/chars.test (with-read-options): new procedure
(R6RS hex escapes): new tests
* test-suite/tests/strings.test (with-read-options): new procedure
(R6RS hex escapes): new tests
R6RS suggests that '\b' should be a string escape for the backspace
character.
* libguile/read.c (scm_read_string): parse backspace escape
* test-suite/tests/strings.test (R6RS backslash escapes): new test
(Guile extensions backslash escapes): remove R6RS escapes from test.
* doc/ref/api-data.texi (Strings): document new string escape
The commit "don't take string-write mutex in read.c:read_token", from
8b0d7b9d94, had a number of bugs. Not sure
how I missed these before.
* libguile/read.c (read_token): Remove a couple of bogus
scm_i_string_stop_writing () calls, now that we no longer take the
string-write mutex.
(read_complete_token): read_token really needs a fresh buffer, which
was not the case when we are reading long tokens and thus hit the
overflow case. Fixes fractions.test.
* libguile/read.c (read_token): Don't take the string-write mutex when
reading a token into a buffer, because it's assumed that the buffer is
fresh (not seen by other threads), and a soft port can call a
procedure that needs the string-write mutex.
They made Sun C 5.8 emit a warning such as:
line 71: warning: dead part of constant expression is nonconstant
* libguile/print.c (scm_print_opts): Don't use `SCM_UNPACK ()' here.
* libguile/read.c (scm_read_opts): Likewise.
* doc/ref/api-evaluation.texi (Character Encoding of Source Files):
Don't suggest `latin1' as a good encoding name since Emacs cannot deal
with it.
* libguile/read.c (scm_file_encoding): Fix "Emacs" spelling.
* libguile/read.c (scm_scan_for_encoding): Rename to ...
(scm_i_scan_for_encoding): ... this; update callers. Use
`scm_gc_strndup ()' instead of `scm_malloc ()'.
* libguile/read.h: Update accordingly.
* libguile/load.c (scm_primitive_load): Don't call free(3) on the value
returned by `scm_i_scan_for_encoding ()'.
Since combining characters, such as accents, modify the appearance of the
previous letter, it looks awkward in its character literal form (#\name)
since it modified the backslash. This instead prints the combining
character on a small circle.
* libguile/chars.h (SCM_CODEPOINT_DOTTED_CIRCLE): new #define
* libguile/print.c (iprint1): print combining characters on dotted circles
* libguile/read.c (scm_read_character): parse the combination of combining
characters and dotted circles
