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 |
5396e592 JH |
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". | |

d7d0d977 | 21 | Multi-threading |
6dd11d31 GS |
22 | support "use Thread;" under useithreads |
23 | add mechanism to: | |
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? | |
29 | Thread::Pool? | |

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 | |

45 | Configure |
46 | make configuring+building away from source directory work (VPATH et al) | |
d57b1ce7 | 47 | this is related to: cross-compilation configuring (see Todo) |
da44fe2a | 48 | _r support (see Todo for mode detailed description) |
1d82895f JH |
49 | POSIX 1003.1 1996 Edition support--realtime stuff: |
50 | POSIX semaphores, message queues, shared memory, realtime clocks, | |
51 | timers, signals (the metaconfig units mostly already exist for these) | |
5b0d9cef | 52 | PREFERABLY AS AN EXTENSION |
1d82895f | 53 | UNIX98 support: reader-writer locks, realtime/asynchronous IO |
5b0d9cef | 54 | PREFERABLY AS AN EXTENSION |
da44fe2a | 55 | IPv6 support: see RFC2292, RFC2553 |
5b0d9cef | 56 | PREFERABLY AS AN EXTENSION |
497711e7 | 57 | there already is Socket6 in CPAN |

59 | Long doubles |
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 | |
55f6b6ec JH |
62 | regexp tricks we had to insert to t/comp/use.t and t/lib/bigfltpm.t, |
63 | (?:9|8999\d+) and the like. | |
64 | ||
65 | 64-bit support | |
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. | |
5b0d9cef | 68 | more pain: long_long, u_long_long. |

45ebb638 | 70 | Locales |
6dd11d31 | 71 | deprecate traditional/legacy locales? |
8bce6328 | 72 | How do locales work across packages? |
6dd11d31 | 73 | figure out how to support Unicode locales |
1d82895f | 74 | suggestion: integrate the IBM Classes for Unicode (ICU) |
8bce6328 | 75 | http://oss.software.ibm.com/developerworks/opensource/icu/project/ |
592fe524 JH |
76 | ICU is "portable, open-source Unicode library with: |
77 | charset-independent locales (with multiple locales | |
78 | simultaneously supported in same thread; character | |
79 | conversions; formatting/parsing for numbers, currencies, | |
80 | date/time and messages; message catalogs (resources); | |
81 | transliteration, collation, normalization, and text | |
82 | boundaries (grapheme, word, line-break))". | |
83 | Check out also the Locale Converter: | |
1d82895f | 84 | http://alphaworks.ibm.com/tech/localeconverter |
592fe524 | 85 | There is also the iconv interface, either from XPG4 or GNU (glibc). |
8bce6328 JH |
86 | iconv is about character set conversions. |
87 | Either ICU or iconv would be valuable to get integrated | |
fe32fb73 | 88 | into Perl, Configure already probes for libiconv and <iconv.h>. |
45ebb638 JH |

90 | Regexen | |
6dd11d31 | 91 | make RE engine thread-safe |
e620704b JH |
92 | a way to do full character set arithmetics: now one can do |
93 | addition, negate a whole class, and negate certain subclasses | |
94 | (e.g. \D, [:^digit:]), but a more generic way to add/subtract/ | |
95 | intersect characters/classes, like described in the Unicode technical | |
96 | report on Regular Expression Guidelines, | |
97 | http://www.unicode.org/unicode/reports/tr18/ | |
98 | (amusingly, the TR notes that difference and intersection | |
99 | can be done using "Perl-style look-ahead") | |
100 | difference syntax? maybe [[:alpha:][^abc]] meaning | |
101 | "all alphabetic expect a, b, and c"? or [[:alpha:]-[abc]]? | |
102 | (maybe bad, as we explicitly disallow such 'ranges') | |
103 | intersection syntax? maybe [[..]&[...]]? | |
b8c5462f | 104 | POSIX [=bar=] and [.zap.] would nice too but there's no API for them |
1d82895f JH |
105 | =bar= could be done with Unicode, though, see the Unicode TR #15 about |
106 | normalization forms: | |
107 | http://www.unicode.org/unicode/reports/tr15/ | |
108 | this is also a part of the Unicode 3.0: | |
109 | http://www.unicode.org/unicode/uni2book/u2.html | |
110 | executive summary: there are several different levels of 'equivalence' | |
592fe524 JH |
111 | trie optimization: factor out common suffixes (and prefixes?) |
112 | from |-alternating groups (both for exact strings and character | |
113 | classes, use lookaheads?) | |
45ebb638 JH |
114 | approximate matching |
115 | ||
19e16c31 JH |
116 | Security |
117 | use fchown, fchmod (and futimes?) internally when possible | |
118 | use fchdir(how portable?) | |
fe32fb73 JH |
119 | create secure reliable portable temporary file modules |
120 | audit the standard utilities for security problems and fix them | |

128 | Win32 stuff | |
6dd11d31 | 129 | sort out the spawnvp() mess for system('a','b','c') compatibility |

131 | |
132 | Miscellaneous | |
157fa422 | 133 | introduce @( and @) because group names can have spaces |
0ff51efc | 134 | add new modules (Archive::Tar, Compress::Zlib, CPAN::FTP?) |
fe32fb73 JH |
135 | sub-second sleep()? alarm()? time()? (integrate Time::HiRes? |
136 | Configure doesn't yet probe for usleep/nanosleep/ualarm but | |
137 | the units exist) | |
138 | floating point handling: nans, infinities, fp exception masks, etc. | |
a3540c92 JH |
139 | At least the following interfaces exist: fp_classify(), fp_class(), |
140 | class(), isinf(), isfinite(), finite(), isnormal(), unordered(), | |
141 | <ieeefp.h>, <fp_class.h> (there are metaconfig units for all these), | |
142 | fp_setmask(), fp_getmask(), fp_setround(), fp_getround() | |
143 | (no metaconfig units yet for these). | |
144 | Don't forget finitel(), fp_classl(), fp_class_l(), (yes, both do, | |
145 | unfortunately, exist), and unorderedl(). | |
5b0d9cef | 146 | PREFERABLY AS AN EXTENSION. |
a3540c92 | 147 | As of 5.6.1 there is cpp macro Perl_isnan(). |
fe32fb73 | 148 | fix the basic arithmetics (+ - * / %) to preserve IVness/UVness if |
157fa422 JH |
149 | both arguments are IVs/UVs: it sucks that one cannot see |
150 | the 'carry flag' (or equivalent) of the CPU from C, | |
151 | C is too high-level... | |
6dd11d31 | 152 | replace pod2html with new PodtoHtml? (requires other modules from CPAN) |
245ccdfc | 153 | automate testing with large parts of CPAN |
fe32fb73 JH |
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) | |
55f6b6ec | 158 | setitimer, getitimer? (the metaconfig units exist) |
