Bombadil 0.3.2 is out, with support for importing local modules and external packages, and importing JSON, text, and binary files!

I've just used this to import Hunspell dictionaries in a spec, checking websites for typos using nspell. This in itself might become a community package you can just import into your Bombadil specs. More broadly, with 0.3.2 we can start reusing action generators and properties.

`rainbow_log` is becoming surprisingly useful!

It takes a regex, runs that on each line, and colors matching lines uniquely based on the matched substring.

I use this daily in my testing work at TigerBeetle.

Playing guitar, and wow it's been some time. Fingers hurt!

This is a song by Lisa Ekdahl that I've tried to Joni Mitchell-ify a bit. Vocals missing obviously.

Good vibes by the sea this morning.
Colors.
Current status: freshing up this lovely 1800's table top with some bee wax. Old furniture with this much soul bring out tears of joy.
This was a heavy one.
