2 finish byte <-> utf8 and localencoding <-> utf8 conversions
3 make substr($bytestr,0,0,$charstr) do the right conversion
4 add Unicode::Map equivivalent to core
5 add support for I/O disciplines
6 - a way to specify disciplines when opening things:
7 open(F, "<:crlf :utf16", $file)
8 - a way to specify disciplines for an already opened handle:
9 binmode(STDIN, ":slurp :raw")
10 - a way to set default disciplines for all handle constructors:
11 use open IN => ":any", OUT => ":utf8", SYS => ":utf16"
12 eliminate need for "use utf8;"
13 autoload byte.pm when byte:: is seen by the parser
14 check uv_to_utf8() calls for buffer overflow
15 make \uXXXX (and \u{XXXX}?) where XXXX are hex digits
16 to work similarly to Unicode tech reports and Java
17 notation \uXXXX (and already existing \x{XXXX))?
18 more than four hexdigits? make also \U+XXXX work?
19 See also "Locales", "Regexen", and "Miscellaneous".
22 support "use Thread;" under useithreads
24 - create new interpreter in a different thread
25 - exchange data between interpreters/threads
26 - share namespaces between interpreters/threads
27 work out consistent semantics for exit/die in threads
28 support for externally created threads?
32 auto-produce executable
33 typed lexicals should affect B::CC::load_pad
34 workarounds to help Win32
35 END blocks need saving in compiled output
37 fix comppadlist (names in comppad_name can have fake SvCUR
38 from where newASSIGNOP steals the field)
41 CPP-space: restrict what we export from headers when !PERL_CORE
42 header-space: move into CORE/perl/?
43 API-space: complete the list of things that constitute public api
46 fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth
47 libswanted <-> usethreads <-> use64bitint <-> use64bitall <->
49 make configuring+building away from source directory work (VPATH et al)
50 this is related to: cross-compilation configuring (see Todo)
51 _r support (see Todo for mode detailed description)
52 POSIX 1003.1 1996 Edition support--realtime stuff:
53 POSIX semaphores, message queues, shared memory, realtime clocks,
54 timers, signals (the metaconfig units mostly already exist for these)
55 PREFERABLY AS AN EXTENSION
56 UNIX98 support: reader-writer locks, realtime/asynchronous IO
57 PREFERABLY AS AN EXTENSION
58 IPv6 support: see RFC2292, RFC2553
59 PREFERABLY AS AN EXTENSION
60 there already is Socket6
63 figure out where the PV->NV->PV conversion gets it wrong at least
64 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
65 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
66 (?:9|8999\d+) and the like.
69 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
70 be in some systems the only thing working as quadtype and uquadtype.
71 more pain: long_long, u_long_long.
74 deprecate traditional/legacy locales?
75 How do locales work across packages?
76 figure out how to support Unicode locales
77 suggestion: integrate the IBM Classes for Unicode (ICU)
78 http://oss.software.ibm.com/developerworks/opensource/icu/project/
79 ICU is "portable, open-source Unicode library with:
80 charset-independent locales (with multiple locales
81 simultaneously supported in same thread; character
82 conversions; formatting/parsing for numbers, currencies,
83 date/time and messages; message catalogs (resources);
84 transliteration, collation, normalization, and text
85 boundaries (grapheme, word, line-break))".
86 Check out also the Locale Converter:
87 http://alphaworks.ibm.com/tech/localeconverter
88 There is also the iconv interface, either from XPG4 or GNU (glibc).
89 iconv is about character set conversions.
90 Either ICU or iconv would be valuable to get integrated
91 into Perl, Configure already probes for libiconv and <iconv.h>.
94 make RE engine thread-safe
95 a way to do full character set arithmetics: now one can do
96 addition, negate a whole class, and negate certain subclasses
97 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
98 intersect characters/classes, like described in the Unicode technical
99 report on Regular Expression Guidelines,
100 http://www.unicode.org/unicode/reports/tr18/
101 (amusingly, the TR notes that difference and intersection
102 can be done using "Perl-style look-ahead")
103 difference syntax? maybe [[:alpha:][^abc]] meaning
104 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
105 (maybe bad, as we explicitly disallow such 'ranges')
106 intersection syntax? maybe [[..]&[...]]?
107 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
108 =bar= could be done with Unicode, though, see the Unicode TR #15 about
110 http://www.unicode.org/unicode/reports/tr15/
111 this is also a part of the Unicode 3.0:
112 http://www.unicode.org/unicode/uni2book/u2.html
113 executive summary: there are several different levels of 'equivalence'
114 trie optimization: factor out common suffixes (and prefixes?)
115 from |-alternating groups (both for exact strings and character
116 classes, use lookaheads?)
120 use fchown, fchmod (and futimes?) internally when possible
121 use fchdir(how portable?)
122 create secure reliable portable temporary file modules
123 audit the standard utilities for security problems and fix them
127 alternate runops() for signal despatch
128 figure out how to die() in delayed sighandler
129 make Thread::Signal work under useithreads
132 sort out the spawnvp() mess for system('a','b','c') compatibility
133 work out DLL versioning
136 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
137 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
138 Configure doesn't yet probe for usleep/nanosleep/ualarm but
140 floating point handling: nans, infinities, fp exception masks, etc.
141 At least the following interfaces exist: fp_classify(), fp_class(),
142 class(), isinf(), isfinite(), finite(), isnormal(), unordered(),
143 <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these),
144 fp_setmask(), fp_getmask(), fp_setround(), fp_getround()
145 (no metaconfig units yet for these).
146 Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do,
147 unfortunately, exist), and unorderedl().
148 PREFERABLY AS AN EXTENSION.
149 As of 5.6.1 there is cpp macro Perl_isnan().
150 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
151 both arguments are IVs/UVs
152 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
153 automate testing with large parts of CPAN
154 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
155 turn Cwd into an XS module? (Configure already probes for getcwd())
156 mmap for speeding up input? (Configure already probes for the mmap family)
157 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
158 setitimer, getitimer? (the metaconfig units exist)
161 keep filenames 8.3 friendly, where feasible
