4d2c4e07 | 10 | Introduction |

13 | EPOC is a OS for palmtops and mobile phones. For more informations look at: |

16 | This is a port of perl to EPOC. It runs on the Psion Series 5, 5mx, |
17 | 5mx Pro, Psion Revo and on the Ericson M128. I have no report about | |
18 | the Psion Netbook or the S7. For information about this hardware | |
19 | please refer to http://www.psion.com. | |

ae2d1787 | 22 | Installation/Usage |
3a2f06e9 | 23 | ===================================================================== |
4d2c4e07 | 24 | |
3a2f06e9 | 25 | You will need ~4MB free space in order to install and run perl. |
ae2d1787 | 26 | |
3a2f06e9 GS |
27 | Install perl.sis on the EPOC machine (most likely a PSION Series 5, |
28 | 5mx). If you do not know how to do that, you are on your own. | |
ae2d1787 | 29 | |
3a2f06e9 GS |
30 | Perl itself and its standard library are using 2.5 MB disk space. I |
31 | left out unicode support modules and modules which will not work with | |
32 | this version. (For details look into epoc/createpkg.pl). If you like | |
33 | to use them, you are free to copy them from a current perl release. | |
ae2d1787 | 34 | |
ed79a026 OF |
35 | Get ESHELL from symbian: |
36 | http://developer.epocworld.com/downloads/progs/Eshell.zip | |
ae2d1787 OF |
37 | |
38 | Now you can enter: perl -de 0 in order to run the perl debugger. If | |
3a2f06e9 | 39 | you are leaving perl, you get into the system screen. You have to |
ed79a026 | 40 | switch back manually to ESHELL. When perl is running, you will see |
3a2f06e9 GS |
41 | a task with the name STDOUT in the task list. |
42 | ||
43 | ====================================================================== | |
44 | IO Redirection | |
45 | ====================================================================== | |
ae2d1787 OF |
46 | |
47 | You can redirect the output with the UNIX bourne shell syntax (this is | |
48 | built into perl rather then eshell) For instance the following command | |
49 | line will run the script test.pl with the output redirected to | |
50 | stdout_file, the errors to stderr_file and input from stdin_file. | |
51 | ||
52 | perl test.pl >stdout_file <stdin_file 2>stderr_file | |
53 | ||
3a2f06e9 GS |
54 | Alternativly you can use 2>&1 in order to add the standard error |
55 | output to stdout. | |
56 | ||
57 | ====================================================================== | |
58 | PATH Names | |
59 | ====================================================================== | |
ae2d1787 | 60 | |
ed79a026 OF |
61 | ESHELL looks for executables in ?:/System/Programs. The SIS file |
62 | installs perl in this special folder directory. The default drive and | |
63 | path are the same as folder the executable resides. The EPOC | |
64 | filesystem is case-preserving, not case-sensitive. | |
65 | ||
66 | EPOC uses the ?: syntax for establishing a search order: First in C: (RAM), | |
67 | then on D: (CF Card) and last in Z: (ROM). | |
68 | ||
69 | The perl @INC search path is now implemented with '?:'. Your perl | |
70 | executable can now live on a different drive than the perl library or | |
71 | even your scripts. | |
ae2d1787 | 72 | |
ed79a026 OF |
73 | ESHELL paths have to be written with backslashes '\', file arguments |
74 | to perl with slashes '/'. Remember that I/O redirection is done | |
75 | internally in perl, so please use slashes for redirects. | |
ae2d1787 | 76 | |
ed79a026 | 77 | perl.exe C:/test.pl >C:/output.txt |
4d2c4e07 | 78 | |
3a2f06e9 | 79 | You can automatically search for file on all EPOC drives with a ? as |
ed79a026 | 80 | the driver letter. For instance ?:\a.txt searches for C:\a.txt, |
3a2f06e9 | 81 | D:\b.txt (and Z:\a.txt). |

91 | Features | |
92 | ==================================================================== | |
4d2c4e07 | 93 | |
ed79a026 | 94 | The built-in function EPOC::getcwd returns the current directory. |

97 | Restrictions | |
98 | ====================================================================== | |
4d2c4e07 | 99 | |
ed79a026 OF |
100 | Features are left out, because of restrictions of the POSIX support in |
101 | EPOC: | |
4d2c4e07 | 102 | |
3a2f06e9 | 103 | + backquoting, pipes etc. |
ae2d1787 | 104 | |
3a2f06e9 GS |
105 | + system() does not inherit ressources like: file descriptors, |
106 | environment etc. | |
ae2d1787 | 107 | |
3a2f06e9 GS |
108 | + signal, kill, alarm. Do not try to use them. This may be |
109 | impossible to implement on EPOC. | |
ae2d1787 | 110 | |
3a2f06e9 | 111 | + select is missing. |
ae2d1787 | 112 | |
3a2f06e9 | 113 | + binmode does not exist. (No CR LF to LF translation for text files) |
ae2d1787 | 114 | |
3a2f06e9 GS |
115 | + EPOC does not handle the notion of current drive and current |
116 | directory very well (i.e. not at all, but it tries hard to emulate | |
117 | one) See PATH. | |
4d2c4e07 | 118 | |
3a2f06e9 GS |
119 | + You need the shell eshell.exe in order to run perl.exe and supply |
120 | it with arguments. | |
4d2c4e07 | 121 | |
3a2f06e9 | 122 | + Heap is limited to 4MB. |
4d2c4e07 | 123 | |
3a2f06e9 | 124 | =================================================================== |
4d2c4e07 | 125 | Compiling Perl 5 on the EPOC cross compiling envionment. |
3a2f06e9 | 126 | =================================================================== |
4d2c4e07 | 127 | |
3a2f06e9 | 128 | Sorry, this is far too short. |
4d2c4e07 | 129 | |
3a2f06e9 | 130 | You will need the C++ SDK from http://developer.epocworld.com/. |
4d2c4e07 | 131 | |
3a2f06e9 | 132 | You will need to set up the cross SDK from |
ed79a026 | 133 | http://members.linuxstart.com/~oflebbe |
4d2c4e07 | 134 | |
3a2f06e9 GS |
135 | You may have to adjust config.sh (cc, cppflags) for your epoc |
136 | install location. | |

167 | I'm offering this port "as is". You can ask me questions, but I can't |
168 | guarantee I'll be able to answer them. |
