* libguile/print.c (symbol_has_extended_read_syntax): Use a more
general, unicode-appropriate algorithm. Hopefully doesn't cause
any current #{}# cases to be unescaped.
(print_extended_symbol): Use more appropriate unicode algorithm, and
emit unicode hex escapes instead of our own lame escapes.
* test-suite/tests/symbols.test: Add tests.
* libguile/strings.c (STRINGBUF_HEADER_SIZE, STRINGBUF_HEADER_BYTES):
New macros.
(STRINGBUF_F_INLINE, STRINGBUF_INLINE, STRINGBUF_OUTLINE_CHARS,
STRINGBUF_OUTLINE_LENGTH, STRINGBUF_INLINE_CHARS,
STRINGBUF_INLINE_LENGTH, STRINGBUF_MAX_INLINE_LEN): Remove.
(STRINGBUF_CHARS, STRINGBUF_WIDE_CHARS): Adjust to return a fixed
location.
(STRINGBUF_LENGTH): Get the length from word 1.
(make_stringbuf, make_wide_stringbuf): Adjust to use a contiguous
memory region.
(wide_stringbuf): Renamed from `widen_stringbuf'. Adjust similarly.
Return the new stringbuf. Callers updated.
(narrow_stringbuf): Likewise.
(scm_sys_string_dump, scm_sys_symbol_dump): Remove `stringbuf-inline'
pair.
* test-suite/tests/strings.test ("string internals")["null strings are
inlined", "short Latin-1 encoded strings are inlined", "long Latin-1
encoded strings are not inlined", "short UCS-4 encoded strings are not
inlined", "long UCS-4 encoded strings are not inlined"]: Remove.
* test-suite/tests/symbols.test ("symbol internals")["null symbols are
inlined", "short Latin-1 encoded symbols are inlined", "long Latin-1
encoded symbols are not inlined", "short UCS-4 encoded symbols are not
inlined", "long UCS-4 encoded symbols are not inlined"]: Remove.
* libguile/hash.c (scm_i_string_hash): new function
(scm_hasher): don't unpack string: use scm_i_string_hash
* libguile/hash.h: new declaration for scm_i_string_hash
* libguile/print.c (quote_keywordish_symbol): use symbol accessors
(scm_i_print_symbol_name): new function
(scm_print_symbol_name): call scm_i_print_symbol_name
(iprin1): use scm_i_print_symbol_name to print symbols
* libguile/print.h: new declaration for scm_i_print_symbol_name
* libguile/symbols.c (lookup_interned_symbol): now takes scheme string
instead of c string; callers changed
(lookup_interned_symbol): add wide symbol support
(scm_i_c_mem2symbol): removed
(scm_i_mem2symbol): removed and replaced with scm_i_str2symbol
(scm_i_str2symbol): new function
(scm_i_mem2uninterned_symbol): removed and replaced with
scm_i_str2uninterned_symbol
(scm_i_str2uninterned_symbol): new function
(scm_make_symbol, scm_string_to_symbol, scm_from_locale_symbol)
(scm_from_locale_symboln): use scm_i_str2symbol
* test-suite/tests/symbols.test: new tests
* libguile/strings.c (scm_i_symbol_substring): Return a read-only string
since R5RS requires `symbol->string' to return a read-only string.
Reported by Bill Schottstaedt <bil@ccrma.Stanford.EDU>.
* test-suite/tests/symbols.test: Add `define-module' clause.
(exception:immutable-string): Adjust to current exception.
("symbol->string")["result is an immutable string"]: Use
`pass-if-exception' instead of `expect-fail-exception'.
* NEWS: Update.
