Recognise shebangs #19

Syntax highlighting seems to br triggered by file types, i.e. file extensions. So that fred.py is highligghted as Python syntax. Unfortunately this means that a file called just fred, which is executable and has #! /usr/bin/env python on the first line is not recognised, hence not highlighted.

Oh this is a good idea. I'm using the rich.syntax.Syntax.guess_lexer method from Rich to handle this currently since the Syntax class is handling almost everything else. In turn it uses pygments to handle it.

I wonder if checking for a shebang would be a welcome addition to the upstream libraries too.
