[Yaml-core] emitter -> composer?

[Clark C . E. <cc...@cl...>]

We are looking for a word that is the opposite
of parser.  I proposed emitter, oren proposed
formatter, and my girlfriend proposed composer.

Any other suggestions?  Composer sounds like
the best one (but I'm biased) and the word 
composer does reflect the idea of constructing
a sequence of characters (notes) from an image.

Best,

Clark
