TWiki System Requirements

Server and client requirements

Low client and server base requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions. Many Plugins and contrib modules exist which enhance and expand TWiki's capabilities; they may have additional requirements.

Server Requirements

TWiki is written in Perl 5, uses a number of shell commands, and requires RCS (Revision Control System), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.

Required CPAN Modules

Module	Preferred version
Algorithm::Diff (included)
Error (included)
Text::Diff (included)
File::Temp	(included with perl 5.6 and later)
Config	>=0
File::Find	>=1.05
IO::File	>=1.10
Time::Local	>=1.11
CGI::Carp	>=1.26
FileHandle	>=2.01
File::Copy	>=2.06
Data::Dumper	>=2.121
Cwd	>=3.05
File::Spec	>=3.05

Optional CPAN Modules

Most of them will probably already be available in your installation. You can check version numbers with the configure script, or if you're still trying to get to that point, check from the command line like this:

perl -e 'use FileHandle; print $FileHandle::VERSION."\n"'

Client Requirements

The TWiki standard installation has relatively low browser requirements:

• HTML 3.2 compliant
• Cookies, if persistent sessions are required

CSS and Javascript are used in most skins, although there is a low-fat skin (Classic skin) available that minimises these requirements. Some skins will require more recent releases of browsers. The default skin (Pattern) is tested on IE 6, Safari, and Mozilla 5.0 based browsers (such as Firefox).

You can easily select a balance of browser capability versus look and feel. Try the installed skins at TWikiSkinBrowser and more at TWiki:Plugins.SkinPackage.

Important note about TWiki Plugins

• Plugins can require just about anything - browser-specific functions, stylesheets (CSS), Java applets, cookies, specific Perl modules,... - check the individual Plugin specs.
  • Note: Plugins included in the TWiki distribution do not add requirements, except for the CommentPlugin which requires Perl 5.6.1.
