LuCI has a simple regex based template processor which parses HTML-files to Lua functions and allows to store precompiled template files. The simplest form of a template is just an ordinary HTML-file. It will be printed out to the user as is.
In LuCI every template is an object with an own scope. It can therefore be instanciated and each instance can has a different scope. As every template processor. LuCI supports several special markups. Those are enclosed in <% %> Tags.
Strip White Space: <%- code -%>
Adding a - right after the opening <% every whitespace before the markup will be stripped.
Adding a - right before the closing %> will equivalently strip every whitespace behind the markup.
Syntax: <% include (templatename) %>
Short-Markup: <%:translation_key default_translation%>
