Before request handler

Execute your code before a request is handled.

void _before ( ) ...

Every Vely request goes through a request dispatcher (i.e. vely_dispatch_request() function), which is auto-generated. In order to specify your code to execute before a request is handled, create a source file "_before.vely" and implement a function "void _before()", which will be automatically picked up and compiled with your application.

If no request executes (for example if your application does not handle a given request), before-request handler does not execute either.

Here is a simple implementation of before-request trigger that just outputs "Getting Started!!":

#include <vely.h>

void _before()
{
    out-header default
    @Getting Started!!
}
