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 better shadow password support: see pp_sys.c:pp_gpwent()
56 UNIX98 support: reader-writer locks, realtime/asynchronous IO
57 IPv6 support: see RFC2292, RFC2553
60 figure out where the PV->NV->PV conversion gets it wrong at least
61 in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the
62 regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t,
63 (?:9|8999\d+) and the like.
66 Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might
67 be in some systems the only thing working as quadtype and uquadtype.
70 deprecate traditional/legacy locales?
71 How do locales work across packages?
72 figure out how to support Unicode locales
73 suggestion: integrate the IBM Classes for Unicode (ICU)
74 http://oss.software.ibm.com/developerworks/opensource/icu/project/
75 ICU is "portable, open-source Unicode library with:
76 charset-independent locales (with multiple locales
77 simultaneously supported in same thread; character
78 conversions; formatting/parsing for numbers, currencies,
79 date/time and messages; message catalogs (resources);
80 transliteration, collation, normalization, and text
81 boundaries (grapheme, word, line-break))".
82 Check out also the Locale Converter:
83 http://alphaworks.ibm.com/tech/localeconverter
84 There is also the iconv interface, either from XPG4 or GNU (glibc).
85 iconv is about character set conversions.
86 Either ICU or iconv would be valuable to get integrated
87 into Perl, Configure already probes for libiconv and <iconv.h>.
90 make RE engine thread-safe
91 a way to do full character set arithmetics: now one can do
92 addition, negate a whole class, and negate certain subclasses
93 (e.g. \D, [:^digit:]), but a more generic way to add/subtract/
94 intersect characters/classes, like described in the Unicode technical
95 report on Regular Expression Guidelines,
96 http://www.unicode.org/unicode/reports/tr18/
97 (amusingly, the TR notes that difference and intersection
98 can be done using "Perl-style look-ahead")
99 difference syntax? maybe [[:alpha:][^abc]] meaning
100 "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]?
101 (maybe bad, as we explicitly disallow such 'ranges')
102 intersection syntax? maybe [[..]&[...]]?
103 POSIX [=bar=] and [.zap.] would nice too but there's no API for them
104 =bar= could be done with Unicode, though, see the Unicode TR #15 about
106 http://www.unicode.org/unicode/reports/tr15/
107 this is also a part of the Unicode 3.0:
108 http://www.unicode.org/unicode/uni2book/u2.html
109 executive summary: there are several different levels of 'equivalence'
110 trie optimization: factor out common suffixes (and prefixes?)
111 from |-alternating groups (both for exact strings and character
112 classes, use lookaheads?)
116 use fchown, fchmod (and futimes?) internally when possible
117 use fchdir(how portable?)
118 create secure reliable portable temporary file modules
119 audit the standard utilities for security problems and fix them
123 alternate runops() for signal despatch
124 figure out how to die() in delayed sighandler
125 make Thread::Signal work under useithreads
128 sort out the spawnvp() mess for system('a','b','c') compatibility
129 work out DLL versioning
132 add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?)
133 sub-second sleep()? alarm()? time()? (integrate Time::HiRes?
134 Configure doesn't yet probe for usleep/nanosleep/ualarm but
136 floating point handling: nans, infinities, fp exception masks, etc.
137 At least the following interfaces exist: fp_classify(), fp_class(),
138 class(), isinf(), isfinite(), finite(), isnormal(), unordered(),
139 <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these),
140 fp_setmask(), fp_getmask(), fp_setround(), fp_getround()
141 (no metaconfig units yet for these).
142 Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do,
143 unfortunately, exist), and unorderedl().
144 As of 5.6.1 there is cpp macro Perl_isnan().
145 fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if
146 both arguments are IVs/UVs
147 replace pod2html with new PodtoHtml? (requires other modules from CPAN)
148 automate testing with large parts of CPAN
149 Unicode collation? http://www.unicode.org/unicode/reports/tr10/
150 turn Cwd into an XS module? (Configure already probes for getcwd())
151 mmap for speeding up input? (Configure already probes for the mmap family)
152 sendmsg, recvmsg? (Configure doesn't probe for these but the units exist)
153 setitimer, getitimer? (the metaconfig units exist)
156 keep filenames 8.3 friendly, where feasible
