console object improvements
---------------------------
Key: CB-348
URL: https://issues.apache.org/jira/browse/CB-348
Project: Apache Callback
Issue Type: Improvement
Components: CordovaJS
Reporter: Patrick Mueller
Assignee: Patrick Mueller
There is some room for improvement in the console object we support in Cordova.
# not all of the common API is supported. Here is the API as implemented by
Firebug, most of which is also implemented in Web Inspector: [Firebug Console
API|http://getfirebug.com/wiki/index.php/Console_API]. An example of the issue
with this is that the weinre demo makes use of markTimeline (actually, that's a
WebKit-only console method - I think the only one!). So the demo dies an early
death, if Cordova's console wins the "overwrite the native" battle.
\\ \\
# which naturally leads to the next issue - the console should daisy chain its
calls to the "native" console, if it exists. An example of this issue is that
if you use iWebInspector on a Cordova app, console logging happens in the Xcode
console, not the iWebInspector console. I'm fine to have it in both places.
\\ \\
# console output operations should "buffer". An example of this issue is that
any console operations which occur BEFORE deviceReady are passed directly to
the bit bucket. Instead, we should "buffer" these, and then when deviceReady
occurs, the console can dump what it's buffered.
Turns out, I have some of these same issues in weinre, but I don't think we can
share an implementation. weinre generally just delegates everything to the
weinre client - eg, arguments to console.log() are sent as 'remote objects',
whereas in Cordova we actually need to evaluate them. The buffering and daisy
chaining should be exactly the same, and perhaps those need to be configured
(eg, console.daisyChainNative(false)) - maybe the code or at least design could
be shared there.
