For more informations look at: -http://www.symbian.com/ +=head1 SYNOPSIS -This is a port of perl to EPOC. It runs on the Psion Series 5, 5mx, -5mx Pro, Psion Revo and on the Ericson M128. I have no report about -the Psion Netbook or the S7. For information about this hardware -please refer to http://www.psion.com. +Perl 5 README file for the EPOC Release 5 operating system. -===================================================================== -Installation/Usage -===================================================================== +=head1 INTRODUCTION -You will need ~4MB free space in order to install and run perl. +EPOC is an OS for palmtops and mobile phones. For more information look +at: L -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. +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: +L -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. +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 L -Get ESHELL from symbian: -http://developer.epocworld.com/downloads/progs/Eshell.zip +Vendors which like to have support for their devices are free to send +me a sample. -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. When perl is running, you will see -a task with the name STDOUT in the task list. +=head1 INSTALLING PERL ON EPOC -====================================================================== -IO Redirection -====================================================================== +You can download a ready-to-install version from +L -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 +L 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. -====================================================================== -PATH Names -====================================================================== +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. -ESHELL looks for executables in ?:/System/Programs. The SIS file -installs perl in this special folder directory. The default drive and -path are the same as folder the executable resides. The EPOC -filesystem is case-preserving, not case-sensitive. +=head1 STARTING PERL ON EPOC -EPOC uses the ?: syntax for establishing a search order: First in C: (RAM), -then on D: (CF Card) and last in Z: (ROM). +Please use the epocemx shell to start perl. perl integrates with the +conventions of epocemx. -The perl @INC search path is now implemented with '?:'. Your perl -executable can now live on a different drive than the perl library or -even your scripts. +=head2 Features of Perl on Epoc -ESHELL paths have to be written with backslashes '\', file arguments -to perl with slashes '/'. Remember that I/O redirection is done -internally in perl, so please use slashes for redirects. +The built-in function EPOC::getcwd returns the current directory. -perl.exe C:/test.pl >C:/output.txt +=head2 Restrictions of Perl on Epoc -You can automatically search for file on all EPOC drives with a ? as -the driver letter. For instance ?:\a.txt searches for C:\a.txt, -D:\b.txt (and Z:\a.txt). +Features are left out, because of restrictions of the POSIX support in +EPOC: -====================================================================== -Editors -====================================================================== +=over 4 -A suitable text-editor can be downloaded -from symbian http://developer.epocworld.com/downloads/progs/Editor.zip +=item * -==================================================================== -Features -==================================================================== +socket IO is only implemented poorly.
