gocsp-select

select from multiple channels, thunks, promises, events, etc

Example

var co = require('gocsp-co')
var select = require('gocsp-select')

co(function* () {
    yield select(s => s
        .take(chan_0, function (val) {
            // default: identity
        })
        .put(chan_1, val, function (ok) {
            // default: identity
        })
        .wait(thunk_or_promise, function (err, data) {
            // default: forward
        })
        .once(event, type, function (a, b, c) {
            // default: identity
        })
        .timeout(1000, function () {
            // default: timeout error
        })
    )
})()

or in coffeescript

co = require 'gocsp-co'
select = require 'gocsp-select'

# probably need latest coffee (1.8.* or 1.9.* ?) for generator syntax
do co ->
  yield select ->
    @take chan_0, (obj) ->
      # default: identity
      # do something
    @put chan_1, val, (ok) ->
      # default: identity
      # do something
    @wait thunk_or_promise, (err, data) ->
      # default: forward
      # do something
    @once event, type, (a, b, c) ->
      # default: identity
      # do something
    @timeout 1000, ->
      # default: timeout error
      # do something
