Version 0.2.2 released
It’s update time and oh boy: what an update!
New CLI
First off, in our slow quest to make the Urn compiler self-hosting we’ve ported the Urn command line interface to Urn. However, this wasn’t just a boring old line-for-line port, the rewrite comes with a whole host of new options:
It uses Urn’s new argument parser library meaning it can handle all standard argument formats, as well as providing more informative help messages. This new CLI also offers finer control: allowing you to disable specific optimisations, add shebangs to your files, automatically set the executable bit, etc…
Contributions from other people
I’d like to say a big thanks to CrazedProgrammer and Lignum. CrazedProgrammer has sent a couple of PRs in, adding a
fancy io library for file manipulation, as well as several additions to the string library. Lignum has put together
a bindings for ComputerCraft, meaning you can use your
favourite APIs inside Urn. Check out the repo for more information and installation instructions.
