One thing I’ve been working on for a little while now is revamping CC: Tweaked documentation situation. As part of that, I had the fantastic idea of “could we run CC: Tweaked in the browser?”, allowing people to run code samples with a click of a button.
Now, at the time, I wasn’t aware of EveryOS’s fantastic Mimic fork, and so I did the only thing logical and went on a long yak shaving expedition. The result of this is copy-cat, a ComputerCraft emulator which runs in your browser.
As it’s original aim was to be used for documentation, it aims to be as accurate and up-to-date as possible. In order to achieve this, copy-cat is built from a modified version of CC: Tweaked’s source code - both the Lua VM and Java APIs behave exactly the same1.
While this is all well and good, that’s not all copy-cat can do. There’s all sorts of other fancy features, including:
- Built-in editor, with access to all of Monaco’s goodness.
- Download the computer’s file contents as a zip file. And then drag-and-drop that zip back into the file browser to open it again!
- Take screenshots and record gifs of the terminal.
- Access to all of ComputerCraft’s settings. You can enable and disable Lua 5.1 support to your heart’s content.
