7 - The Console only does "ASCII" input: e.g. pressing the "2"
8 key five times, "aaaaa", does not produce "รค" ("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"?)
22 - the $^E does not work
23 - select() does not work (not our fault)
24 - starting external application: what now (0.1.0) works is:
27 - and those with arguments:
28 - system("app arg1 arg2")
29 - system("app arg1 arg2 &")
30 but remember that a Symbian process does get only argv[0]
31 and argv[1]: all the arguments of the application are passed
32 in as a single argument, the second one ("arg1 arg2" in the above)
35 - piped open, in either direction
37 - fork/wait (these unlikely to ever work as in POSIX)
38 - IO redirection or filename globbing in system()
39 (since there is no POSIX shell beneath)
40 What might work in future:
41 - some I/O redirection
42 - exec() might be made to work
43 - Symbian::spawn("cmd args") returning a process id (what does Win32 do?)
44 - Symbian::waitpid($spawned_pid)
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
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.
59 - Slash versus Backslash: where does one need to use "\\"?
60 writing Perl applications, where can one get away with using "/" ?
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)
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/
86 - review for proper Symbian coding practices
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
97 - Make it possible to call UI elements (or any other Symbianic
98 asynchronous services) from Perl.
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
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)
119 - in S60 2.6 (at least in Nokia 6630 v4.03.11) launching scripts via
120 FExplorer does not open up the console
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
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.
139 =head1 CPAN LIBRARIES
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):
146 - Archive::Tar (now included in 5.9.x)
147 - Term::ReadKey (useless?)
148 - Term::ReadLine (useless?)
156 - Crypt::SSLeay? (ssl?)
162 - XML? XML::Simple? (expat?) (there is builtin xml support)
165 - DBD::SQLite? (sqlite?)
168 =head1 CORE LIBRARIES
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.
180 =head1 REGRESSION SUITE
182 - how to run the standard test suite on a Symbian device?
184 =head1 FUTURE POSSIBILITIES
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:,
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?)
