add (task) helper to pass in curried tasks about ember-concurrency HOT 7 CLOSED

I think this is what you want (though you might want to rename some things):

// template
{{search-input on-input=search}}

// component
<input type="text" value={{query}} oninput={{perform on-input value="target.value"}}>
{{if (get on-input 'isRunning') "never true"}}

The perform helper produces a regular ol function that's compatible with APIs expecting you to pass in closure actions / functions. The way you had it, you were basically doing a lookup of isRunning on a function, rather than a task. If you're writing a component that is task-aware, you can just pass in the task directly, and then call perform on the task from within the component's template.

Would be nice, status on this?

@Padchi still thinking through some ideas about whether this should be task-helper specific or whether in JS it should be easy to create tasks that are curried versions of other tasks.

I don't think this was my problem tho. I just want to pass down a task to a component, perform it from the component and be able to to see if it's running or not. Maybe I'm doing something wrong but isRunning is undefined:

// template 
{{search-input on-input=(perform search)}}

// component
<input type="text" value={{query}} oninput={{action on-input value="target.value"}}>
{{if (get on-input 'isRunning') "never true"}}

Well that work's except that the value that is passed to the task is the whole oninput event:
Event {isTrusted: true, type: "input", target: input, currentTarget: input, eventPhase: 2…}

@Padchi I believe that's fixed on master but I still need to cut a release :/ will try and get that out soon.

(task) has now been implemented and released in 0.6.0, as is support for value="..."; there is an example for value="" at the bottom of http://ember-concurrency.com/#/docs/writing-tasks
