Lua Scriptlet Example

<%lua -- -- Defer this page -- if conversation:getQuery():get('defer') == 'true' then if conversation:defer() then conversation:stop() end end -- -- Cache this page -- caching:setDuration(5000) -- -- Calling Java -- system = luajava.bindClass('java.lang.System') print(string.format('

This page was dynamically generated at %s

', system:currentTimeMillis())) -- -- An example of a function -- function print_adapter (adapter) %>

Adapter: <%= adapter:getAttributes():get('name') %> version <%= adapter:getAttributes():get('version') %>
Language: <%= adapter:getAttributes():get('language.name') %> version <%= adapter:getAttributes():get('language.version') %>
Tags: <% local tags = adapter:getAttributes():get('tags'):toArray() for i = 1, #tags do io.write(tags[i]) if i < #tags then io.write(', ') end end %>

<% end %>

Language used:

<% print_adapter(executable:getContext():getAdapter()) %>

Available languages:

<% adapters = executable:getManager():getAdapters():toArray() for i = 1, #adapters do print_adapter(adapters[i]) end %>

The "id" attribute in the URL query is:

<%= conversation:getQuery():get('id') or '' %>

A few tests:

<% -- -- Including a document -- -- This is identical to: -- -- document:include('/triple/lua/') -- %> <%& '/triple/lua/' %> <% for i = 0, 9 do %> A multiple of three: <% print_triple(i) %>
<% end %>
