newb question : Logging / Debugging

I read the page on doing logging/debugging but cannot seem to get any PUTS or log statements to show up on the console or in my rholog.txt file.

I'm sure I am missing something simple here.

This is a callback on an HTTP processor.   The show_error/show_results page will be displayed (if I change/comment the RhoLog.Error call) so I know we are getting to this point in the code.   However if I use puts, rholog.error, app_info, or app_error I can seem to get the test string to show up anywhere.   My guess is I'm looking in the wrong file(s)/console or have missed a config setting to enable this.

  def httpget_callback

    if @params['status'] != 'ok'

        @@error_params = @params

        WebView.navigate((url_for :action => :show_error))       

    else

      @@get_result = @params["body"]

 

      begin

        require "rexml/document"

 

        doc = REXML::Document.new(@@get_result)

        puts "doc : #{doc}"

      rescue Exception => e

        puts "Error: #{e}"

        @@get_result = "Error: #{e}"

      end

      Rholog.Error("category","************ MESS ****************")

      WebView.navigate( url_for(:action => :show_result) )

    end

    Rholog.Error("category","************ MESS 22 ****************")

    WebView.navigate((url_for :action => :show_result))

  end

My rhoconfig.txt:

# Rhodes log properties

# log level

# 0-trace, 1-info(app level), 3-warnings, 4-errors

# for production set to 3

MinSeverity  = 0

# enable copy log messages to standard output, useful for debugging

LogToOutput = 1

# '*' means all categories, otherwise list them : Cat1, Cat2

LogCategories = *

# what categories to exclude

Hi Darryn -

Thanks for the clues.

The remote object (logging text file) does not exist.   I can't seem to get this to be created regardless of my settings in the rhoconfig file.

hmmm... I've never used the product on Android so I'm not the expert... but I thought the log should also be output to logcat, do you see anything at logcat?. 

To see all the device messages, run adb -d logcat and start the application on your device.

OK, that is bizarre.   I am doing this in the code...

  puts "************* STORELOCATIONS **************"
  app_info "*** STORE LOCATIONS ***"
  app_error "*** SL error ***"

And now I am getting ALL THREE lines of logging output!!!

I/APP (18659): I 06/08/2012 16:59:23:959 00004911              APP| ************* STORELOCATIONS **************
I/APP (18659): I 06/08/2012 16:59:23:959 00004911 APP StoresController| *** STORE LOCATIONS ***
I/APP (18659): E 06/08/2012 16:59:23:960 00004911 APP StoresController| *** SL error ***

Baffling, but at least I'm getting somewhere.  I wonder if I can take out the app_error now and still see my app_info output.     

Could adding in app_error have triggered something in the build process?   Turning on a config flag possibly?     I've been trying to get those other 2 lines to show up for the past 27 builds!

Either way I can at least get output now, thanks!

I am not getting output with just app_info()

However I am new to Eclipse, Ruby, and Rhostudio so it is possible this was coming out in the log before but I simply wasn't finding it.    Though a routine ^f search in the console window was not locating the output, which is fairly rudimentary IDE/debug process stuff.

Thanks again for your help, Rob.    

I'm really liking what I see with Rho* over any other cross-platform mobile frameworks.    It is MUCH faster than anything else we've used even though the underlying principles and concepts are the same.  

Phonegap + JQM, for  example, is VERY laggy on the Android UI.      Rhomobile, same technique is MUCH more responsive.    The bytecode engine seems to be very well done.     If this  passes the litmus test with the GPS Droid/IOS apps we will be launching some very prominent services based on the platform by end-of-summer.     

Looks promising.  I'm hoping to be giving the entire Rho team props in my annual "state of mobile development" presentation this October.

Let me know what you need. 

Let me know what you need.  Just the contents of the project directory for Eclipse?    Anything from the Rhostudio install directory?

Also, the issue is resolved at this point.  I added app_error, ran, got ALL my debug ouput, removed app_error and still get my app_info output.

It is possible, though unlikely, I just missed the output before.     I'd hate to have people chasing down a non-issue.
