For more informations look at: +http://www.symbian.com/ -There are many features left out, because of restrictions of the posix -support in the SDK. +This is a port of Perl version 5.5.650 to EPOC. It runs on the Perl +Series 5, Series 5mx and the Psion Revo. I have no reports for other +EPOC devices. -The following known problems do exist: +Features are left out, because of restrictions of the POSIX support. -1) very little testing. +===================================================================== +Installation/Usage +===================================================================== -2) no support for system, backquoting, pipes etc. One cannot exec a - different process. +You will need ~4MB free space in order to install and run perl. -3) no signals, kill. Do not try to use them. +Install perl.sis on the EPOC machine (most likely a PSION Series 5, +5mx). If you do not know how to do that, you are on your own. -4) select is missing. +Perl itself and its standard library are using 2.5 MB disk space. I +left out unicode support modules and modules which will not work with +this version. (For details look into epoc/createpkg.pl). If you like +to use them, you are free to copy them from a current perl release. -5) binmode does not work. (No CR LF to LF translation for text files) +Copy eshell.exe from the same page you got perl to your EPOC device. +Start eshell.exe with a double tap. -6) no Config.pm +Now you can enter: perl -de 0 in order to run the perl debugger. If +you are leaving perl, you get into the system screen. You have to +switch back manually to eshell.exe When perl is running, you will see +a task with the name STDOUT in the task list. -7) no I/O redirection. +====================================================================== +IO Redirection +====================================================================== -8) it may not run from a drive other than C: (I have no CF Card to test) +You can redirect the output with the UNIX bourne shell syntax (this is +built into perl rather then eshell) For instance the following command +line will run the script test.pl with the output redirected to +stdout_file, the errors to stderr_file and input from stdin_file. -9) sockets may hardly of any use. +perl test.pl >stdout_file stderr_file -10) You need a shell in order to run perl.exe. +Alternativly you can use 2>&1 in order to add the standard error +output to stdout. +====================================================================== +PATH Names +====================================================================== +Pathnames to executables in eshell.exe have to be written with +backslashes '\', file arguments to perl with slashes '/'. The default +drive of perl is the same as the drive perl.exe is located on, the +default path seems to be '/'. + +i.e. command lines look a little bit funny: + +D:\perl.exe C:/test.pl >C:/output.txt + +You can automatically search for file on all EPOC drives with a ? as +the driver letter. For instance ?:\a.txt seraches for C:\a.txt, +D:\b.txt (and Z:\a.txt). + +====================================================================== +Editors +====================================================================== + +You may have a problem to create perl scripts. A cumbersome workaround +is to use the OPL Editor and exporting to text. + +The OPL+ Editor is quite good. (Shareware: http://www.twiddlebit.com) +There is a port of vim around: + http://www.starship.freeserve.co.uk/index.html + +====================================================================== +Restrictions +====================================================================== + +The following things are left out of this perl port: + ++ backquoting, pipes etc. + ++ system() does not inherit ressources like: file descriptors, + environment etc. + ++ signal, kill, alarm. Do not try to use them. This may be + impossible to implement on EPOC. + ++ select is missing. + ++ binmode does not exist. (No CR LF to LF translation for text files) + ++ EPOC does not handle the notion of current drive and current + directory very well (i.e. not at all, but it tries hard to emulate + one) See PATH. + ++ You need the shell eshell.exe in order to run perl.exe and supply + it with arguments. + ++ Heap is limited to 4MB. + +=================================================================== Compiling Perl 5 on the EPOC cross compiling envionment. --------------------------------------------------------- +=================================================================== -0.
