Free software portal

The Sputnik Wiki is a lightweight, cross-platform example of the wiki software application type. It is written in Lua and runs over multiple web servers (Apache/CGI and Kepler/Xavante). A basic Sputnik wiki runs in about 2000 LOC complete. The product's extensibility and configurability allows it to be morphed into other types of webapps, such as a photo album, bug tracker (in 120 lines of code), blog, or calendar.

Features

Differentiating features (among Wikis) include:

• A Sputnik/Kepler installation uses 1Mb.^[1]
• No-compile installation
• Sputnik ships with the webapp stack included.
• Lua installation not required
• root/Administrator not required

Architecture

The Webapp architecture stacks up like this:

• Configuration managed by configuration nodes, which perform actions sent to them as much as describe configuration.
• Plugins via LuaRocks (Markup, Storage, Authentication/CAPTCHA, etc.)
• Cosmo templates
• Markup: Markdown, Medialike, or POD
• Saci document storage system, somewhat similar to a CMS.
• Versium storage management API.
• Storage options: Database (SQLite3 or MySQL) and Git
• Kepler
• Xavante, an http server using Copas (below)
• Copas
• LuaSocket
• Lua
