       use IO::Interactive::Tiny ();

       if (Web::Detect::detect_web_fast()) {
           # do HTML
       }
       else {
           # do CLI
           if (IO::Interactive::Tiny::is_interactive()) {
               # prompt/ANSI/etc
           }
           else {
               # do not prompt/plain text/etc

DESCRIPTION

   Knowing if you are under a web environment or not is very handy.

   For example, often you need to decide whether to output HTML or
   plaintext.

FUNCTIONS

   Functions are exportable but are not exported by default.

detect_web() => HASHREF

   Return false if not detected running under any web environment.

   Return a hash otherwise.

   These keys exists if it is detected that we are running under the given
   environment and the value is suitable as a boolean (always true).
