trick to make eco templates work well with asset pipeline

eco-snipppet.coffee

# Client side eco templating
assets.jsCompilers.eco =
        match: /\.eco$/
        compileSync: (sourcePath, source) ->
                fileName = path.basename sourcePath, '.eco'
                directoryName = (path.dirname sourcePath).replace "#{__dirname}/public/js/templates", ""
                jstPath = if directoryName then "#{directoryName}/#{fileName}" else "/#{fileName}"
                "(function() {window.JST || (window.JST = {});window.JST['#{jstPath}'] = #{eco.precompile source}}).call(this);"

app.set 'view engine', 'eco'
app.set 'views', __dirname + '/public/js/templates'
