       # Introduction
       
       I will explain how to configure Kakoune to automatically use a filetype
       (for completion/highlighting..) depending on the filename or its
       extension.
       
       # Setup
       
       The file we want to change is ~/.config/kak/kakrc , in case of issue
       you can use ":buffer *debug*" in kakoune to display the debug output.
       
       ## Filetype based on the filename
       
       I had a case in which the file doesn't have any extension.  This
       snippet will assign the filetype Perl to files named Rexfile.
       
       ```kakoune configuration example
       hook global BufCreate (.*/)?Rexfile %{
               set buffer filetype perl
       }
       ```
       
       ## Filetype based on the extension
       
       While this is pretty similar to the previous example, we will only
       match any file ending by ".gmi" to assign it a type markdown (I know
       it's not but the syntax is quite similar).
       
       ```kakoune configuration example
       hook global BufCreate .*\.gmi %{
               set buffer filetype markdown
       }
       ```
