TWiki Implementation Notes

Platforms and System Requirements

TWiki is written in Perl 5 and also uses some shell commands. The current implementation runs best on a Unix machine, but it is also possible on Microsoft Windows. RCS (for revision control) must be installed on the system. [ MM: Locate elsewhere and/or include one-liner and link for RCS... ]

Required Environment by Platform
Packages: Linux/Unix: Windows:
Perl 5.x 5.x
Non-standard Perl modules   MIME::Base64, Digest::SHA1 (for password generation)
Optional Perl modules Net::SMTP (or sendmail) Net::SMTP
RCS 5.7 5.7 (including diff
Other external programs ls, fgrep, egrep ls, fgrep, egrep
Web server Apache Apache, IIS
OS versions Linux, Unix... every last Win?!

Directory Structure

You can easily rename the root TWiki directory - twiki - to whatever you like by changing a configuration file value. For the simplest installation and future upgrades, you should leave the subdirectory structure exactly as is:

Directory: Files: Used for:
twiki list Start-up info
twiki/bin list Perl scripts
twiki/lib list Configuration file & main library
twiki/lib/TWiki list Perl modules
twiki/lib/TWiki/Plugins list TWikiPlugins Perl modules
twiki/pub list Public support files (ex: FileAttachments, images) and RCS histories)
twiki/data list Topic text (page content) and RCS histories;
twiki/templates list HTML templates, used by TWiki scripts

Note: about the additional directories in data, elsewhere
