6dd11d31 | 1 | Unicode support |
d1edabcf GS |
2 | finish byte <-> utf8 and localencoding <-> utf8 conversions |
3 | make substr($bytestr,0,0,$charstr) do the right conversion | |
6dd11d31 GS |
4 | add Unicode::Map equivivalent to core |
5 | add support for I/O disciplines | |
d1edabcf GS |
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" | |
6dd11d31 | 12 | eliminate need for "use utf8;" |
d1edabcf | 13 | autoload byte.pm when byte:: is seen by the parser |
560a288e | 14 | check uv_to_utf8() calls for buffer overflow |

d7d0d977 | 17 | Multi-threading |
6dd11d31 GS |
18 | support "use Thread;" under useithreads |
19 | add mechanism to: | |
20 | - create new interpreter in a different thread | |
21 | - exchange data between interpreters/threads | |
22 | - share namespaces between interpreters/threads | |
23 | work out consistent semantics for exit/die in threads | |
24 | support for externally created threads? | |
25 | Thread::Pool? | |

37 | CPP-space: restrict what we export from headers when !PERL_CORE |
38 | header-space: move into CORE/perl/? | |

42 | fix the vicious cyclic multidependency of cc <-> libpth <-> loclibpth |
43 | libswanted <-> usethreads <-> use64bitint <-> use64bitall <-> | |
44 | uselargefiles <-> ... | |
45ebb638 | 45 | make configuring+building away from source directory work (VPATH et al) |
d57b1ce7 | 46 | this is related to: cross-compilation configuring (see Todo) |
da44fe2a | 47 | _r support (see Todo for mode detailed description) |
1d82895f JH |
48 | POSIX 1003.1 1996 Edition support--realtime stuff: |
49 | POSIX semaphores, message queues, shared memory, realtime clocks, | |
50 | timers, signals (the metaconfig units mostly already exist for these) | |
51 | UNIX98 support: reader-writer locks, realtime/asynchronous IO | |
da44fe2a | 52 | IPv6 support: see RFC2292, RFC2553 |

54 | Long doubles |
55 | figure out where the PV->NV->PV conversion gets it wrong at least | |
56 | in AIX and Tru64 (V5.0 and onwards) when using long doubles: see the | |
55f6b6ec JH |
57 | regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t, |
58 | (?:9|8999\d+) and the like. | |
59 | ||
60 | 64-bit support | |
61 | Configure probe for quad_t, uquad_t, and (argh) u_quad_t, they might | |
62 | be in some systems the only thing working as quadtype and uquadtype. | |

45ebb638 | 64 | Locales |
6dd11d31 | 65 | deprecate traditional/legacy locales? |
8bce6328 | 66 | How do locales work across packages? |
6dd11d31 | 67 | figure out how to support Unicode locales |
1d82895f | 68 | suggestion: integrate the IBM Classes for Unicode (ICU) |
8bce6328 | 69 | http://oss.software.ibm.com/developerworks/opensource/icu/project/ |
1d82895f JH |
70 | and check out also the Locale Converter: |
71 | http://alphaworks.ibm.com/tech/localeconverter | |
8bce6328 JH |
72 | ICU is "portable, open-source Unicode library with: |
73 | charset-independent locales (with multiple locales simultaneously | |
74 | supported in same thread; character conversions; formatting/parsing | |
75 | for numbers, currencies, date/time and messages; message catalogs | |
76 | (resources) ; transliteration, collation, normalization, and text | |
77 | boundaries (grapheme, word, line-break))". | |
78 | There is also 'iconv', either from XPG4 or GNU (glibc). | |
79 | iconv is about character set conversions. | |
80 | Either ICU or iconv would be valuable to get integrated | |
fe32fb73 | 81 | into Perl, Configure already probes for libiconv and <iconv.h>. |

83 | Regexen | |
6dd11d31 | 84 | make RE engine thread-safe |
e620704b JH |
85 | a way to do full character set arithmetics: now one can do |
86 | addition, negate a whole class, and negate certain subclasses | |
87 | (e.g. \D, [:^digit:]), but a more generic way to add/subtract/ | |
88 | intersect characters/classes, like described in the Unicode technical | |
89 | report on Regular Expression Guidelines, | |
90 | http://www.unicode.org/unicode/reports/tr18/ | |
91 | (amusingly, the TR notes that difference and intersection | |
92 | can be done using "Perl-style look-ahead") | |
93 | difference syntax? maybe [[:alpha:][^abc]] meaning | |
94 | "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]? | |
95 | (maybe bad, as we explicitly disallow such 'ranges') | |
96 | intersection syntax? maybe [[..]&[...]]? | |
b8c5462f | 97 | POSIX [=bar=] and [.zap.] would nice too but there's no API for them |
1d82895f JH |
98 | =bar= could be done with Unicode, though, see the Unicode TR #15 about |
99 | normalization forms: | |
100 | http://www.unicode.org/unicode/reports/tr15/ | |
101 | this is also a part of the Unicode 3.0: | |
102 | http://www.unicode.org/unicode/uni2book/u2.html | |
103 | executive summary: there are several different levels of 'equivalence' | |

107 | use fchown, fchmod (and futimes?) internally when possible | |
108 | use fchdir(how portable?) | |

122 | Miscellaneous | |
0ff51efc | 123 | add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?) |
fe32fb73 JH |
124 | sub-second sleep()? alarm()? time()? (integrate Time::HiRes? |
125 | Configure doesn't yet probe for usleep/nanosleep/ualarm but | |
126 | the units exist) | |
127 | floating point handling: nans, infinities, fp exception masks, etc. | |
a3540c92 JH |
128 | At least the following interfaces exist: fp_classify(), fp_class(), |
129 | class(), isinf(), isfinite(), finite(), isnormal(), unordered(), | |
130 | <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these), | |
131 | fp_setmask(), fp_getmask(), fp_setround(), fp_getround() | |
132 | (no metaconfig units yet for these). | |
133 | Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do, | |
134 | unfortunately, exist), and unorderedl(). | |
135 | As of 5.6.1 there is cpp macro Perl_isnan(). | |
fe32fb73 JH |
136 | fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if |
137 | both arguments are IVs/UVs | |
6dd11d31 | 138 | replace pod2html with new PodtoHtml? (requires other modules from CPAN) |
245ccdfc | 139 | automate testing with large parts of CPAN |

140 | Unicode collation? http://www.unicode.org/unicode/reports/tr10/ |
141 | turn Cwd into an XS module? (Configure already probes for getcwd()) | |
142 | mmap for speeding up input? (Configure already probes for the mmap family) | |
143 | sendmsg, recvmsg? (Configure doesn't probe for these but the units exist) | |
55f6b6ec | 144 | setitimer, getitimer? (the metaconfig units exist) |
