For more informations look at: +http://www.symbian.com/ -You will need ~4MB free space in order to run perl. +This is a port of perl to the epocemx SDK by Eberhard Mattes, which +itself uses the SDK by symbian. Essentially epocemx it is a POSIX +look alike environment for the EPOC OS. For more information look at: +http://epocemx.sourceforge.net/ -Install perl.sis on the EPOC machine (most likely a PSION Series -5). If you do not know how to do that, you are on your own. You may -have to use a CF Card in order to work with perl. The perl debugger -uses more then 1.5 MB additional RAM. The heap is limited to 2 MB. +perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, +Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc +Release 3 Hardware (Series 5 classic), too. For more information about +this hardware please refer to http://www.psion.com/ -Perl itself and its standard library are using 1.7MB disk space. I -left out UTF support and modules which will not work with this -version. (For details look into epoc/createpkg.pl). +Vendors which like to have support for their devices are free to send +me a sample. -Copy eshell.exe to the same location as perl. Start eshell.exe with a -double click. +=head1 INSTALLING PERL ON EPOC -Now you can enter: perl -de 0 in order to run the perl debugger. If -you are leaving perl, you have to switch back manually to eshell.exe -(With Ctrl-System or the button in the upper right corner of the -System screen.) When perl is running, you will see a task with the -name STDOUT in the task list. +You can download a ready-to-install version from +http://www.oflebbe.de/oflebbe/perl/ -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. +You will need at least ~6MB free space in order to install and run perl. -perl test.pl >stdout_file stderr_file +Please install the emxusr.sis package from +http://epocemx.sourceforge.net/ first. -Alternativly you can use 2>&1 in order to add the standard error output to -stdout. +Install perl.sis on the EPOC machine. If you do not know how to do +that, consult your PsiWin documentation. -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 -is the path perl.exe is / (???). +Perl itself and its standard library is using 4 MB disk space. +Unicode support and some other modules are left out. (For details, +please look into epoc/createpkg.pl). If you like to use these modules, +you are free to copy them from a current perl release. -i.e. command lines look a little bit funny: +=head1 STARTING PERL ON EPOC -D:\perl.exe C:/test.pl >C:/output.txt +Please use the epocemx shell to start perl. perl integrates with the +conventions of epocemx. -In order to use Getopt::Long you have to autosplit this module by hand: run +=head2 Editors on Epoc -\perl.exe \autosplit.pl in order to create the necessary files. +A suitable text editor can be downloaded from symbian +http://www.symbian.com/developer/downloads/files/editor.zip -You may have a problem to create perl scripts. A cumbersome workaround -is to use the OPL Editor and exporting to text. +=head2 Features of Perl on Epoc -Problems --------- +The built-in function EPOC::getcwd returns the current directory. -The following known problems exist: +=head2 Restrictions of Perl on Epoc -1) no support for system, backquoting, pipes etc. One cannot exec a - different process. +Features are left out, because of restrictions of the POSIX support in +EPOC: -2) no signals, kill, alarm.
