Radreise-Wiki:Ini.pl

ini.pl enthält die Pfade des Hauptverzeichnisses Wiki-Content ($baseDir) und des Output-Verzeichnisses ($outDir). In letzterem landen alle generierten Dateien (kmz-Files, Imagemaps und Kilometrierungen). Ebenso müssen $username und $password an die lokalen Gegebenheiten angepasst werden. Das Output-Verzeichnis wird nicht automatisch angelegt. Des weiteren sind ein paar globale Encoding-Routinen und ein Filewriter im Skript enthalten.

Quellcode des Skripts:

use strict;

my $baseDir   = "../";
my $outDir    = '../out';

my $encoding = 'utf-8';  # Unicode
my $encAnsi  = 'cp1252'; # Windows Ansi
my $encOut   = 'cp850' ; # DOS Shell
