Instant Feedback for C Programming in Nano

I learned to program using python. Therefore the method I follow for learning is very experimental, I type in a bit of code, see what happens, tweak until its right then incorporate it into the larger program. With the interactive interpreter, this is easy, and can be accomplished in quite the rapid fire fashion. When I started learning C I wanted something similar, so I figured out a fine little one-liner that I was running in a split of a screen session that I had my editor running in.

gcc -x c - < hello.c; ./a.out

I came to notice that gedit has an 'External Tools' plugin which lets you execute commands in a window within the editor. So I created a tool that with one keypress will compile and execute whatever is currently on screen (saved or not). This works well for my purposes on testing non-interactive code.

To set that up in gedit;
Edit>Preferences>Plugins, Enable 'External Tools'
Tools>External Tools>New
Commands:

#!/bin/sh
gcc -x c - -o $HOME/.tempc;
$HOME/.tempc
rm .tempc

Fun!
