Sputnik (http://sputnik.freewisdom.org/) generates RSS for changes to
wiki pages. The relevant code is:
1. A template library called "Cosmo" (http://sputnik.freewisdom.org/en/Cosmo)
2. A Cosmo template for RSS 2.0:
RSS = [====[<rss version="2.0">
<channel>
<title>$title</title>
<description/>
<link>$baseurl</link>
$items[[
<item>
<link>$link</link>
<title>$title</title>
<guid isPermalink="$ispermalink">$guid</guid>
<description>$summary</description>
</item>]]
</channel>
</rss>
]====]
3. Code that fills it with the appropriate content (somewhat
simplified from the actual Sputnik usage):
return cosmo.fill(templates.RSS, {
title = "My RSS Feed",
baseurl = MY_BASE_URL,
items = function()
for i, page in ipairs(recently_changed_pages) do
cosmo.yield{
link = page.url,
title = page.title.." change by "..page.author,
ispermalink = "false",
guid = page.name .. "/" .. page.version,
summary = page.summary
}
end
end,
}), "application/rss+xml"
