/whois merb

•started as a hack

•http://pastie.org/14416

•3 parts: core, more, plugins

•less opinions

•ORM agnostic

•view agnostic

•JS agnostic

•“no code is faster than no code”

merb-core

•actionpack light

•routing, controllers, bootloader, rack

•merb-guts

merb-more•the rest of actionpack, with a little activesupport

•merb-mailer, merb-haml, merb-action-args

render/display

•what the action returns, the client is served

•explicit

•render a view

•display a resource

merb-action-args

•allows an action to receive parameters as arguments

•uses ParseTree

regex routes

•complex routes that don’t always fit the slash as a separator pattern

•view matchers use Hpricot

we ain’t got no rspec

•merb_test_unit

•works great with shoulda

•merb_stories
