1=encoding utf8 2 3=head1 BASE PORT 4 5=head2 Console 6 7- The Console only does "ASCII" input: e.g. pressing the "2" 8 key five times, "aaaaa", does not produce "ä" ("a diaeresis"), 9 but instead the "2" key rotates through "abc2abc2...". 10 This is a pity because the Console is actually capable of full 11 Unicode input and output (if you have the fonts, that is). You 12 can verify this by entering e.g. the euro character, which is 13 U+20AC, well beyond U+00FF. I don't know why the full repertoire 14 of the keyboard is not available. 15- Enhance the console? (line editing, full x-y movement, history) 16- The role of the console needs to be rethought: the best way 17 would be to have the console visible in the same screen as 18 the GUI elements (an "embedded console"?) 19 20=head2 Core Language 21 22- the $^E does not work 23- select() does not work (not our fault) 24- starting external application: what now (0.1.0) works is: 25 - system("app"); 26 - system("app&"); 27 - and those with arguments: 28 - system("app arg1 arg2") 29 - system("app arg1 arg2 &") 30 but remember that a Symbian process does get only argv[0] 31 and argv[1]: all the arguments of the application are passed 32 in as a single argument, the second one ("arg1 arg2" in the above) 33 What does not work: 34 - I/O redirection 35 - piped open, in either direction 36 - qx/backtick/` 37 - fork/wait (these unlikely to ever work as in POSIX) 38 - IO redirection or filename globbing in system() 39 (since there is no POSIX shell beneath) 40 What might work in future: 41 - some I/O redirection 42 - exec() might be made to work 43 - Symbian::spawn("cmd args") returning a process id (what does Win32 do?) 44 - Symbian::waitpid($spawned_pid) 45 46=head2 Platform 47 48- in S60 1.2 (at least in 3650 Nokia 3650 v3.11) setjmp/longjmp is 49 fragile (see Symbian FAQ-0929), intensive debugging and fix needed 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 (see symbian\ext\README and symbian\ext\Moped\Msg\README) 66- now the .mmp functions both as input and as output - bad 67- MakeMaker? Pure PM, PM + XS? 68- currently the PerlApp UID is in both config.pl (hardwired) and 69 in makesis.pl (computed), this is quite error prone 70- Enable building also under Cygwin? (could be really hard, 71 the Symbian SDKs pretty much assume cmd.exe) 72 73=head1 PACKAGING 74 75- subdivide perlext.sis? 76- pm-stripper: strip pod and comments, while inserting the appropriate 77 #line commands to keep linenumbers in sync. Shaves off easily 50% 78 of the code, making install packages smaller. 79- Get MakeMaker to create SIS packages? In non-Win32? 80- Symbian has APIs for opening .zip files 81- Investigate Autrijus Tang's PAR format 82 http://www.autrijus.org/par-intro/ 83 84=head1 PerlBase 85 86- review for proper Symbian coding practices 87 88=head1 PerlApp 89 90- In "Run" see how one could show also the file extensions. 91- How to allow passing command line options to scripts being run? 92- Terminate/Pause menu entries (to be used while the script is running)? 93- review for proper Symbian coding practices 94 95=head2 All UIs 96 97- Make it possible to call UI elements (or any other Symbianic 98 asynchronous services) from Perl. 99 100 There is now a sample of enabling calling CPerlUi::TextQueryDialogL() 101 from Perl as PerlApp::TextQuery(), see symbian_utils.c. This, however, 102 does not work: calling the dialog code blocks so that the screen is not 103 redrawn at all. Perl should do both: "yield" so that the GUI framework 104 can redraw, but in the meanwhile Perl should wait for the completion 105 (OK or Cancel) of the dialog, but Perl must not exit the current PL_op. 106 Welcome to the wonderful world of cooperative multitasking. The right 107 solution surely involves Active Objects. The problem may require having 108 a different Perl op dispatch loop than the standard and debug ones in 109 run.c and dump.c. 110 111- menu/toolbar support 112- selection lists (single cf multi cf radio) 113- on/off (special case of two-item radio selection list) 114- forms (multicontrols) 115- "secret editor" (special case of text query) 116 117=head2 Series 60 118 119- in S60 2.6 (at least in Nokia 6630 v4.03.11) launching scripts via 120 FExplorer does not open up the console 121 122=head2 Series 80 123 124- On exit "PerlApp" gets Symbian USER Panic 44: "This panic is raised 125 by the Free() and FreeZ() member functions of an RHeap. It is caused 126 when the cell being freed overlaps the next cell on the free list 127 (i.e. the first cell on the free list with an address higher than the 128 one being freed)." Reason unknown. 129- Hotkey Newline so that it functions as 'OK' in dialogs 130 131=head2 UIQ 132 133- UIQ 3.0? UIQ 2.0? (now only tried in UIQ 2.1) 134- UIQ, at least UIQ 2.1, does not have "file select dialogs" since 135 "files" are supposed to be hidden from the user. Therefore, no 136 "Run" in PerlApp. (For similar stylistic reasons there is no "Exit".) 137- Long notes (e.g. the EPerlAppCommandAbout) are shown badly truncated. 138 139=head1 CPAN LIBRARIES 140 141- Include/Package more modules (or work harder on getting CPAN.pm working?) 142 (but note that lib/**/*.pm is 3.5 megabytes, probably not worth including 143 all of it, even after pm-stripping): 144 - libnet 145 - Bundle::CPAN 146 - Archive::Tar (now included in 5.9.x) 147 - Term::ReadKey (useless?) 148 - Term::ReadLine (useless?) 149 - Bundle::LWP 150 - URI 151 - HTML::TagSet 152 - HTML::Parser 153 - HTML::Entities 154 - HTML::HeadParser 155 - LWP 156 - Crypt::SSLeay? (ssl?) 157 - IMAP? 158 - Net::Telnet? 159 - Archive::Zip? 160 - Mail::Send? 161 - Date::Calc? 162 - XML? XML::Simple? (expat?) (there is builtin xml support) 163 - RSS? 164 - DBI (DBD::???) 165 - DBD::SQLite? (sqlite?) 166 - SOAP? XML-RPC? 167 168=head1 CORE LIBRARIES 169 170- Fix Devel::PPPort (worth it?) (Note that there is D::PPP 3.x out by now) 171- Fix Encode to not to have writeable data: seems to be tricky indeed 172 because of copious global non-const data. 173- Verify that the modified File::Spec::Win32 does work in Symbian. 174 (File::Spec::Epoc does not seem to be relevant?) 175- What does Cwd really do since the concept of cwd is a bit fuzzy in Symbian. 176- What should Sys::Hostname return? GPRS? BT? WLAN? 177- ByteLoader problem: byterun.c does not see VERSION and XS_VERSION. 178- POSIX problem: STDLIB POSIX is not that POSIX. 179 180=head1 REGRESSION SUITE 181 182- how to run the standard test suite on a Symbian device? 183 184=head1 FUTURE POSSIBILITIES 185 186- GUI support (problematic that the MVC model enforces an "application") 187 (name suggestion: Moped::Gui) 188 (see above for the need of sorting out the Active Objectedness) 189- Messaging support (sms:, mms:, mailto:, irdaobex:, btobex:, 190 cell location, WLAN) 191 (name suggestion: Moped::Msg) 192- PDA support (address book) 193 (name suggestion: Moped::PDA) 194- Device support (memory, camera) 195 (name suggestion: Moped::Dev::Memory, Moped::Dev::Drives, Moped::Dev::Camera) 196- Phone APIs (e.g. how to catch an incoming call: BIO messaging) 197- Remote console (Bluetooth/IR/USB?) 198 199
