Unicode support
finish byte <-> utf8 and localencoding <-> utf8 conversions
make substr($bytestr,0,0,$charstr) do the right conversion
- a way to set default disciplines for all handle constructors:
use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
eliminate need for "use utf8;"
- autoload utf8_heavy.pl's swash routines in swash_init()
autoload byte.pm when byte:: is seen by the parser
check uv_to_utf8() calls for buffer overflow
(see also "Locales", "Regexen", and "Miscellaneous")
API-space: complete the list of things that constitute public api
Configure
+ fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
+ libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
+ uselargefiles <-> ...
make configuring+building away from source directory work (VPATH et al)
- _r support
- cross-compilation configuring
+ this is related to: cross-compilation configuring (see Todo)
+ _r support (see Todo for mode detailed description)
POSIX 1003.1 1996 Edition support--realtime stuff:
POSIX semaphores, message queues, shared memory, realtime clocks,
timers, signals (the metaconfig units mostly already exist for these)
UNIX98 support: reader-writer locks, realtime/asynchronous IO
+ IPv6 support: see RFC2292, RFC2553
Long doubles
figure out where the PV->NV->PV conversion gets it wrong at least
in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
- regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t.
+ regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
+ (?:9|8999\d+) and the like.
+
+64-bit support
+ Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
+ be in some systems the only thing working as quadtype and uquadtype.
Locales
deprecate traditional/legacy locales?
+ How do locales work across packages?
figure out how to support Unicode locales
suggestion: integrate the IBM Classes for Unicode (ICU)
- http://www10.software.ibm.com/developerworks/opensource/icu/index.html
+ http://oss.software.ibm.com/developerworks/opensource/icu/project/
and check out also the Locale Converter:
http://alphaworks.ibm.com/tech/localeconverter
- ICU has it all: locales and character sets, the 'iconv' seems to have
- 'only' the character sets. Either would be valuable to get integrated
+ ICU is "portable, open-source Unicode library with:
+ charset-independent locales (with multiple locales simultaneously
+ supported in same thread; character conversions; formatting/parsing
+ for numbers, currencies, date/time and messages; message catalogs
+ (resources) ; transliteration, collation, normalization, and text
+ boundaries (grapheme, word, line-break))".
+ There is also 'iconv', either from XPG4 or GNU (glibc).
+ iconv is about character set conversions.
+ Either ICU or iconv would be valuable to get integrated
into Perl, Configure already probes for libiconv and <iconv.h>.
- How do locales work across packages?
Regexen
make RE engine thread-safe
+ a way to do full character set arithmetics: now one can do
+ addition, negate a whole class, and negate certain subclasses
+ (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
+ intersect characters/classes, like described in the Unicode technical
+ report on Regular Expression Guidelines,
+ http://www.unicode.org/unicode/reports/tr18/
+ (amusingly, the TR notes that difference and intersection
+ can be done using "Perl-style look-ahead")
+ difference syntax? maybe [[:alpha:][^abc]] meaning
+ "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
+ (maybe bad, as we explicitly disallow such 'ranges')
+ intersection syntax? maybe [[..]&[...]]?
POSIX [=bar=] and [.zap.] would nice too but there's no API for them
=bar= could be done with Unicode, though, see the Unicode TR #15 about
normalization forms:
floating point handling: nans, infinities, fp exception masks, etc.
at least the following interfaces exist: fp_classify(), fp_class(),
class(), isnan(), isinf(), isfinite(), finite(), isnormal(),
- fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
- ieeefp.h, fp_class.h. There are metaconfig units for all of these.
+ ordered(), fp_setmask(), fp_getmask(), fp_setround(), fp_getround(),
+ ieeefp.h, fp_class.h. There are metaconfig units for most of these.
+ Search for ifdef __osf__ in pp.c to find a temporary fix that
+ needs to be done right.
fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
both arguments are IVs/UVs
replace pod2html with new PodtoHtml? (requires other modules from CPAN)
turn Cwd into an XS module? (Configure already probes for getcwd())
mmap for speeding up input? (Configure already probes for the mmap family)
sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
- setitimer, getitimer? (the units exist)
+ setitimer, getitimer? (the metaconfig units exist)

keep filenames 8.3 friendly, where feasible
