Show HN: X11 tool to share a screen area in any video meeting

I love how simple this is- Barely 100 lines or C++ (ignoring comments). That's one thing that makes me prefer X11 over Wayland.

there's very little code because there's very little error handling / sanity checking. not saying X11 isn't hackable and cool, but a lot of code gets bloated and complex (and robust!) by not assuming perfect usage.

for example. run ./clipscreen 1 2 3 4

True. If something goes wrong this will just crash. But to be fair, the only error handling I could think of would probably just exit with a vague error message... Pull requests to make it more robust welcome anyway!
