Open Source Programmers Stink At Error Handling

I got your fix RIGHT HERE!

I'll be blunt. Open source programmers need to stop being so darned lazy about e rror handling. That obviously doesn't include all open source programmers. You k now who you are.

If you want a demonstration of what I mean, start your favorite GUI-based open s ource applications from the command line of an X terminal instead of a menu or i con. In most cases this will cause the errors and warnings that the application generates to appear in the terminal window where you started it. (There are exce ptions, depending on the application or the script that launches the application .)

Many of the applications I use on a daily basis generate anywhere from a few war nings or error messages to a few hundred. And I'm not just talking about the deb ug messages that programmers use to track what a program is doing. I mean warnin g messages about missing files, missing objects, null pointers, and worse.

I'll be blunt, too. I got your fix RIGHT HERE! I have whipped up some open source magic that uses a powerful error-finding heuristic in combination with a correction algorithm. It should fix all of these problems you have described.

#!/bin/bash

if [ "$#" -lt "1" ]; then
echo "Usage:" $0 "<program> {<args>}
exit 1
fi

$* 2>/dev/null
echo "All errors corrected!"

You are not expected to understand how this works. Send me beer, we open source guys like that.
