Hi, all!
I'm finally done with my Lua decoder and thought I would post a link to
it here, both for any constructive criticism anyone might have and for
helping out anyone who was in the same situation I was in. Here's the link:

Looks quite reasonable to me. Nice work!
This was basically born out of the need to parse fractional seconds in
the WebSphere systemout.log files. Go's time package doesn't recognize
separators that aren't periods. (There's an open issue for adding
support for commas, at least.) So I was unable to use
PayloadRegexDecoder; I saw no way to do it other than writing a Lua
decoder or a Go decoder.
Using Lua and LPeg is the recommended way to do parsing in Heka.
PayloadRegexDecoder is available for very simple cases, but it's not very fast
nor is it very flexible, and there is very little benefit to writing a custom
Go decoder.
Thanks for sharing your code.
