It is a quick hack that was not ment for publication, I'm not proud of it:
#!/usr/bin/lua
fd_out = nil
function w(...)
fd_out:write(string.format(...) .. "\n")
end
fd = io.open("manual.html")
html = fd:read("*a")
fd:close()
while true do
name, html = html:match('<a name=".-"><code>(.-)</code></a></h3>(.*)')
fd_out = io.open("man3/" .. name .. ".3", "w")
w('.TH %s 3 "2010" "Lua 5.1" "Lua 5.1 manual"', name:upper())
w('.SH NAME')
w(name)
api = nil
api, tmp = html:match('^<p>\n<span class="apii">(.-)</span>(.*)')
if api then
api = api:gsub("<em>(.-)</em>", "%1")
html = tmp
end
proto, html = html:match("<pre>(.-)</pre>(.*)")
w('.SH SYNOPSIS')
for l in proto:gmatch("([^\n]+)") do
w('.B " %s', l)
w('.br')
end
w('.br\n')
if api then
w('%s\n', api)
w('.br\n')
end
desc, html = html:match("(.-)<h3>(.*)")
w('.SH DESCRIPTION')
if not desc then break end
desc = desc:gsub("<hr>", "")
desc = desc:gsub("§", "#")
desc = desc:gsub(" ", " ")
desc = desc:gsub("<a.->(.-)</a>", "%1")
desc = desc:gsub("<p>", "\n.br\n")
desc = desc:gsub("</?ul>", "")
desc = desc:gsub("<li>(.-)</li>", "%1")
desc = desc:gsub("<b>(.-)</b> *", "\n.B %1\n")
desc = desc:gsub("<em>(.-)</em> *", "\n.B %1\n")
desc = desc:gsub("<pre>(.-)</pre>", ".nf%1.fi")
desc = desc:gsub("<code>(.-)</code> *", "\n.I %1\n")
desc = desc:gsub("\n\n", "\n")
w("%s", desc)
end
