TWiki System Requirements
Server and client requirements for TWiki 01-Sep-2004
Low client and server requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions.
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.
* Current documentation mainly covers Linux and Apache installations. See WindowsInstallCookbook for a Windows installation guide. See TWiki:Codev.TWikiOn for help with installation on various platforms including Unix, MacOS X, Apache
|| Required Server Environment *

diff 2.7 or higher is required when not using the all-Perl RcsLite.

Optional, but the all-Perl RCS replacement is not currently recommended for live sites - see TWiki:Codev.RcsLite
| Web server
|| Apache 1.3 is well supported; Apache 2.0 is not recommended yet (see TWiki:Codev.IssuesWithApache2dot0).
For other servers, CGI support, authentication, extended path info required; also, the
register script is likely to need significant changes
mod_perl, web hosts, etc.
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
- no cookies
- no CSS (if the ClassicSkin is used)
You can easily add functionality, by customizing TWikiTemplates
, for one, while tailoring the browser requirements to your situation.
- The 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.
