Claude helped test and clean up a pure-Ruby terminal

rubyterm is an X11 terminal built entirely in Ruby. Its font rendering and X11 bindings are also written in Ruby, and it is used as a regular replacement for xterm by its maker.

It supports double-width and double-height text, Unicode, layered fonts, special handling for box-drawing characters, and fairly complete behavior. It is available as a Rubygem and includes an , so it can run a terminal inside another terminal.

Most of the code was written by hand, but Claude was used over the last few days to create a , find several bugs, and begin and cleaning up the codebase. The code still has rough parts.
