1 | =head1 BASE PORT |
2 | |
3 | =head2 Console |
4 | |
5 | - The Console only does "ASCII" input: e.g. pressing the "2" |
6 | key five times, "aaaaa", does not produce "รค" ("a diaeresis"), |
7 | but instead the "2" key rotates through "abc2abc2...". |
8 | This is a pity because the Console is actually capable of full |
9 | Unicode input and output (if you have the fonts, that is). You |
10 | can verify this by entering e.g. the euro character, which is |
11 | U+20AC, well beyond U+00FF. I don't know why the full repertoire |
12 | of the keyboard is not available. |
13 | - Enhance the console? (line editing, full x-y movement, history) |
14 | - The role of the console needs to be rethought: the best way |
15 | would be to have the console visible in the same screen as |
16 | the GUI elements (an "embedded console"?) |
17 | |
18 | =head2 Core Language |
19 | |
20 | - the $^E does not work |
21 | - select() does not work (not our fault) |
22 | - starting external application: what now (0.1.0) works is: |
23 | - system("app"); |
24 | - system("app&"); |
25 | - and those with arguments: |
26 | - system("app arg1 arg2") |
27 | - system("app arg1 arg2 &") |
28 | but remember that a Symbian process does get only argv[0] |
29 | and argv[1]: all the arguments of the application are passed |
c8f896e5 |
30 | in as a single argument, the second one ("arg1 arg2" in the above) |
27da23d5 |
31 | What does not work: |
c8f896e5 |
32 | - I/O redirection |
27da23d5 |
33 | - piped open, in either direction |
34 | - qx/backtick/` |
35 | - fork/wait (these unlikely to ever work as in POSIX) |
36 | - IO redirection or filename globbing in system() |
37 | (since there is no POSIX shell beneath) |
38 | What might work in future: |
c8f896e5 |
39 | - some I/O redirection |
27da23d5 |
40 | - exec() might be made to work |
41 | - Symbian::spawn("cmd args") returning a process id (what does Win32 do?) |
42 | - Symbian::waitpid($spawned_pid) |
43 | |
44 | =head2 Platform |
45 | |
46 | - in S60 1.2 (at least in 3650 Nokia 3650 v3.11) setjmp/longjmp is |
47 | fragile (see Symbian FAQ-0929), intensive debugging and fix needed |
0added8b |
48 | - in S60 2.6 (at least in Nokia 6630 v4.03.11) launching scripts via |
27da23d5 |
49 | FExplorer does not open up the console |
50 | |
51 | =head2 Unicode |
52 | |
53 | - Symbian has Unicode filenames, and Unicode all over the place. |
54 | - Encode and the use of Symbian Unicode in general |
55 | tie into the overall usefulness of PerlIO. |
56 | |
57 | =head2 Portability |
58 | |
59 | - Slash versus Backslash: where does one need to use "\\"? |
60 | writing Perl applications, where can one get away with using "/" ? |
61 | |
62 | =head2 Build |
63 | |
64 | - make xsbuild.pl much more robust (for building external extensions) |
65 | - MakeMaker? Pure PM, PM + XS? |
66 | - currently the PerlApp UID is in both config.pl (hardwired) and |
67 | in makesis.pl (computed), this is quite error prone |
68 | - Enable building also under Cygwin? |
69 | |
70 | =head1 PACKAGING |
71 | |
72 | - subdivide perlext.sis? |
73 | - pm-stripper: strip pod and comments, while inserting the appropriate |
74 | #line commands to keep linenumbers in sync. Shaves off easily 50% |
75 | of the code, making install packages smaller. |
76 | - Get MakeMaker to create SIS packages? In non-Win32? |
77 | - Symbian has APIs for opening .zip files |
78 | - Investigate Autrijus Tang's PAR format |
79 | http://www.autrijus.org/par-intro/ |

81 | =head1 PerlBase |
82 | |
83 | - review for proper Symbian coding practices |
84 | |
85 | =head1 PerlApp |
86 | |
87 | - In "Run" see how one could show also the file extensions. |
88 | - when autostarting also offer to display the file (via Notes?) |
89 | instead of installing/running it? |
90 | - Allow passing command line options to scripts being run? |
91 | - Add "OneLiner" menu item? (-e, -M) (requires a UI form) |
92 | - Terminate/Pause menu entries? |
93 | - review for proper Symbian coding practices |
94 | |
95 | =head1 CORE LIBRARIES |
96 | |
97 | - Fix Devel::PPPort (worth it?) (Note that there is D::PPP 3.x out by now) |
98 | - Fix Encode to not to have writeable data: seems to be tricky indeed |
99 | because of copious global non-const data. |
100 | - Verify that the modified File::Spec::Win32 does work in Symbian. |
101 | (File::Spec::Epoc does not seem to be relevant?) |
102 | - What does Cwd really do since the concept of cwd is a bit fuzzy in Symbian. |
103 | - What should Sys::Hostname return? GPRS? BT? WLAN? |
104 | - ByteLoader problem: byterun.c does not see VERSION and XS_VERSION. |
105 | - POSIX problem: STDLIB POSIX is not that POSIX. |
106 | |
107 | =head1 REGRESSION SUITE |
108 | |
109 | - how to run the standard test suite on a Symbian device? |
110 | |
111 | =head1 CPAN LIBRARIES |
112 | |
113 | - Include/Package more modules (or work harder on getting CPAN.pm working?) |
114 | (but note that lib/**/*.pm is 3.5 megabytes, probably not worth including |
115 | all of it, even after pm-stripping): |
116 | - libnet |
117 | - Bundle::CPAN |
118 | - Archive::Tar |
27da23d5 |
119 | - Term::ReadKey (useless?) |
120 | - Term::ReadLine (useless?) |
121 | - Bundle::LWP |
122 | - URI |
123 | - HTML::TagSet |
124 | - HTML::Parser |
125 | - HTML::Entities |
126 | - HTML::HeadParser |
127 | - LWP |
128 | - Crypt::SSLeay? (ssl?) |
27da23d5 |
129 | - IMAP? |
130 | - Net::Telnet? |
131 | - Archive::Zip? |
132 | - Mail::Send? |
133 | - Date::Calc? |
134 | - XML? XML::Simple? (expat?) (there is builtin xml support) |
135 | - RSS? |
c042ae3a |
136 | - DBI (DBD::???) |
27da23d5 |
137 | - DBD::SQLite? (sqlite?) |
138 | - SOAP? XML-RPC? |
139 | |
140 | =head1 FUTURE POSSIBILITIES |
141 | |
142 | - Remote console (Bluetooth/IR) |
143 | - S60 GUI support |
144 | - S60 PDA support |
145 | - Phone APIs |
146 | - S80 |
147 | - UIQ |
