## Templates
See [online wiki](https://github.com/openwrt/luci/wiki/Templates) for latest version.
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 instanced and each instance can have a different scope.
As every template processor. LuCI supports several special markups. Those are enclosed in `<% %>`-Tags.
By adding `-` (dash) 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.
