Atom Custom File Type Detection

In this example I will show you how you can set OpenCart’s .tpl file extension to read as PHP when opening in Atom Editor.

Open your config.cson file. Underneath core: add:

customFileTypes:
        'text.html.php': [
            'tpl'
    ]

text.html.php is the “source” and the tpl is the file extension. Now when you open a .tpl file it will read as a PHP file by default.

If you want any other custom file types you can follow this format, full directions found on flight manual.
