The same way you would for other events, such as your :on-click example. Here's a little something to get you started: https://www.refheap.com/73581 Also, getting info from things *while* you are dragging can be quite difficult. I'd suggest using storage-atom for this: https://github.com/alandipert/storage-atom. It plays quite well with Reagent. -- Note that posts from new members are moderated - please be patient with your first post. --- You received this message because you are subscribed to the Google Groups "ClojureScript" group.

Re: [ClojureScript] Wrong script order
Thanks! I somehow had Javascript in mind... where you don't declare the
dependencies (kinda overlooked the :require part in my scripts). But it makes
sense ;)

[ClojureScript] Error Running Advanced Unit Tests of Modern ClojureScript Tutorial
I'm working through the (great!) Modern ClojureScript tutorials. I'm working on tutorial 16. I'm in the section named "Dancing alone on the client-side of the browser." When I run the ClojureScript unit tests, the whitespace tests and the simple tests pass, but the advanced tests fail. Because of all the changes made by the Google Closure Compiler, I'm uncertain how to even start diagnosing this issue. I've tried to follow the tutorial steps faithfully; however, I have included the most up-to-date of the various libraries mentioned in the tutorial. I did try reverting back to clojurescript.test to 0.2.1 and I see similar (but not identical) behavior. I've attached my project.clj file for information. What recent experience have others had running unit tests in these three different configurations? Thanks. -- Note that posts from new members are moderated - please be patient with your first post. --- You received this message because you are subscribed to the Google Groups "ClojureScript" group.

Components do not handle state changes themselves, they request state changes via cursors. Cursors handle state changes and cursors are a customizable abstraction by the user. If you want a component to write its state elsewhere go for it. People continue to think that cursors do both more and less than they actually do. I encourage people to actual read and fully understand source before coming to any conclusions as to their purpose.

[ClojureScript] Re: Om cursors explained
I too have been thinking about the concept of cursors. Cursors are meant to enable reusable components but the way I see it they can easily couple your view code with the rest of your program (they are mutable and are meant to be used that way). If every component takes (and uses) a cursor are we back to a network of mutable stuff? I think you can achieve the same level of reuse with either callbacks or channels. As a simple example should a button component expose an on-click event (or a click channel) or fiddle with application state directly via cursors, which is more reusable? I suppose it’s possible to not use cursors when you don’t have to and I think that in many cases it’s better for components to not handle state changes directly themselves and instead emit (either via channels or callbacks) data about user interactions which can be handled separately by a different part of your program.

Re: [ClojureScript] Re: Om cursors explained
Interacting with cursors is restricted to render for *consistency*. No one should be able to mutate the data during render, it's that simple. In between renders we do not allow interacting with cursors for *consistency* beyond the few operations covered in the documentation and docstrings. This is because it's not possible to know who is changing the state between renders (outside of subscribing to :tx-listen). On Tue, Apr 8, 2014 at 3:06 PM, William Sommers wrote: > > what’s the role of IValue and ICloneable in cursors life? > Not sure. > ICloneable can be converted to cursors for free. IValue exists because for various reasons you may want to read a *stale* value in an event handler or go loop or whatever. Generally you should not do this and instead deref. deref is only allowed outside of render because of ... *consistency*. During render you have consistent picture of the world. Outside rendering you do not. > why do we have to implement ICloneable on Strings (in an immutable > language!) in order for cursors to work? > Not sure. The documentation and the tutorials now specifically state to not do this. It's only there for people who absolutely are OK with the myriad of issues around JavaScript natives versus objects for String/Number/Boolean/etc. I show this only to demonstrate it's possible achieve uniform handling of values at the leaves of your application state. I don't actually recommend it in practice. While I'm not taking pull requests on Om, documentation like this is a great place for people to start and continue contributing.

Re: [ClojureScript] Om cursrors explained
Those are a lot of interesting questions best answered by just hunkering down and reading the source. Once you understand them please feel free to add a documentation section to the Om wiki that answers these questions if you feel inclined. A design goal of Om is for it to be small enough that more detail oriented questions not addressed by existing documentation can be quickly answered by reading some code. If you still have questions, feel free to ask for clarifications.

Reading through script/bootstrap, it appears that we always downloads latest during bootstrap, which would indicate that we're not actually depending on a specific version of the closure-compiler?

In order to test the new Closure compiler you need to update the bootstrap
script to download the right jar. The project.clj is only for development
and is not actually involved in managing ClojureScript dependencies in
anyway.

[ClojureScript] Export properties and methods?
I'm using deftype and the Object protocol to create objects with properties and methods that are natural to use from JS client code. But I can't get this to work with advanced optimizations enabled, it seems that only functions can be exported with the ^:export tag. Is this true? It seems like it would be possible to export the methods and properties using the closure exportProperty and exportSymbol functions and I could write a macro to do this automatically, but I just want to make sure that an existing solution does not already exist.
