TWiki Requirements

Server and client system requirements; file system structure

Overview

Maintaining minimum client and server requirements is necessary to keep TWiki deployment as broad as possible.

Server-Side Requirements

TWiki is written in Perl 5 and uses a number of shell commands. It requires GNU RCS (Revision Control System) to be installed on the same system. TWiki is developed in a standard Linux/Apache environment. It can also work with Microsoft Windows and other platforms.

Required Server Environment
Resource	Unix	Windows
Perl	5.005_03 or higher
Non standard Perl modules	Net::SMTP (or sendmail)	Net::SMTP, MIME::Base64, Digest::SHA1
RCS	5.7 or higher
Other external programs	ls, fgrep, egrep
Web server	Apache; others (with support for CGI, authentication, extended path) *

Current documentation covers Linux only. Compiling a basic TWikiOnWindows installation guide is an ongoing effort.

Client-Side Requirements

The TWiki standard installation has extremely low browser requirements:

• HTML 3.2 compliant
• minimal use of JavaScript in the user interface (degrades gracefully)
• no cookies
• no CSS

TWiki generates XHTML 1.0 code as long as it is compatible with HTML 3.2.

Known Issues

• The new TWikiPlugins feature currently does not have any compatibility guidelines for developers. Plugins can require just about anything: browser-specific functions, stylesheets (CSS), Java, cookies, etc.
