Ask HN: Created my first Ruby Gem. How'd I do?

Last weekend I was working on a Rails project and realized that I was creating the same utility function for the third time in a row. In the spirit of DRY, I figured it was time to package it up into a gem that I could drop into any project.

The basic problem was creating a place to quickly and easily shove config values and application wide state. CONSTANTS in the environment work ok, but can't be modified by the run time. What I ultimately wanted was memcache, with persistence.

So I created the entity_store gem, which allows you to drop a persistent key/value store into any rails app in about 5 minutes. After initialization, you can use commands like:

# Get key value.

e = EntityStore["testkey"]

e = EntityStore.testkey

e = EntityStore[:testkey]

# sets key named 'happened' to a Time object of now

EntityStore[:happened] = Time.now

EntityStore["happened"] = Time.now

EntityStore.happened = Time.now

Everything syncs instantly with the database, so state is preserved even if the server goes down. Additionally, it allows you to initialize with some defaults for keys - which works great for getting initial state going on your app.

Overall, packaging up and publishing the gem in a decent state online took longer than actually writing the functionality. Talk about yak shaving! But it was fun... hope someone else finds it useful.

Any ideas for the next version would be greatly appreciated.
