Sorry for delay, I will check it soon and write to you results :)

top -b -n 1 should work.

On my side though, no matter what I use, ps, top, df, I don't get output with the top example. Heck, even if I use gon.watch.top = "Some String" does not work. I could only get it to work if I set gon.watch.top = Time.now in the controller. In the source, I do see `gon.top=" PID TTY TIME CMD\n 8<..snipped..8<", but nothing is seen in the html.

@wari I solved the same problem using to_json. For example:

gon.watch.top = `top -b -n 1`.to_json

Great @fermuch! I think I missed here to_json call on value https://github.com/gazay/gon/blob/master/lib/gon/watch.rb#L50. I have to check it

Thanks @fermuch btw, @gazay I wanted to re-report this issue (as promised in rdrc), but hey, had a long holiday in Bali, and the internet is bad there. ;)

Still does not explain why Time.now works without converting to JSON

Not sure if this is the right place for this, but I am also seeing the issue that gon.watch does not seem to work when passing in a string.

For example, gon.watch.var1 = "foo" does not work, but putting the string in an array like gon.watch.var1 = ["foo"] does work.

There are some problems while using watch. Maybe the best to do is to call a to_json on every object, and then use base64 to pass the variable, so we avoid unexpected calls. So, the client has to first transform base64 into JSON, and then parse the JSON.

What do you think about this?

I'm looking at a push solution and this seemed like the lightweight solution to fit my needs. So I tried the gon.watch.top example. Like to the others I ran into the issue with ubuntu 12x. Solved with suggestions posted. However, if I use the controller variable top (gon.watch.top), gon.watch.top or gon.all_variables returns nil (logged debug). If I change it to something else as in btop voila, values. The next issue is the data will not update the dom element. I get a continuous reload of the top.html.erb view but no data. It's a copy paste example and hard to screw up. The only change I made to example source was "top" to "btop". A view source shows the data getting picked up by gon.watch.btop but never makes it to the DOM. What might I be missing here?

TIA!

I cannot replicate your error. You can try by encoding to base64 and decoding in your function before using the data.

No joe. I deleted and recreated the example project. Interestingly, when <%= include_gon :watch => true %> is included in the application.html layout file, the value of gon.watch.top = nil when logging the result out to log each time the top method is called. If I remove the include tag and call the top method then gon.watch.top has the result of the top -n1 -b call. Would there be a version conflict?
