TWiki System Requirements

TWiki System Requirements

Server and client requirements for TWiki 01-Dec-2001

Low client and server requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions.

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 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 CGI support, authentication, extended path)

* Current documentation covers Linux/Apache only. See TWiki:Codev/TWikiOnWindows for work-to-date on a Windows installation guide.

Client Requirements

The TWiki standard installation has extremely low browser requirements:

HTML 3.2 compliant
generates XHTML 1.0 pages that are compatible with HTML 3.2
minimal use of JavaScript in the user interface (degrades gracefully)
no cookies
no CSS

You can easily add functionality, by customizing TWikiTemplates, for one, while tailoring the browser requirements to your situation.

Known Issues

The new TWikiPlugins feature currently does not have compatibility guidelines for developers. Plugins can require just about anything - browser-specific functions, stylesheets (CSS), Java applets, cookies, specific Perl modules,... - check the individual Plugin specs.
- Plugins included in the TWiki distribution do not add requirements.
