How access to the command line in the console panel from my extension?

[Ebrahim]

Hi everybody,

Could you please help me how can I access to the command line in the console panel from my extension? 

I want to programmatically copy a script within my extension in the command line, run it, when is done, clear the editor. 

Thanks for any help,

Ebrahim

The Command Line implementation (module) is here:
https://github.com/firebug/firebug/blob/master/extension/content/firebug/console/commandLine.js

You can see how getExpression is done
https://github.com/firebug/firebug/blob/master/extension/content/firebug/console/commandLine.js#L719

and how clear() is done
https://github.com/firebug/firebug/blob/master/extension/content/firebug/console/commandLine.js#L375

Thanks Honza for your reply.

I am not sure I am right, but I use the following code to set value in the editor. 

-----------------------------------------------------------------------

context.commandLineText = "MY_SCRIPT_COMES_HERE";

-----------------------------------------------------------------------

My another question is that how can I trigger the "Run" button from my extension? 

Thanks again, 

Ebrahim

I don't think this would work correctly .

Take yet a look at our automated test framework here:
typeCommand:
https://github.com/firebug/firebug/blob/master/tests/FBTest/content/FBTestFirebug.js#L1313

Again you can see our test harness here, executeCommand:

Thank you very much Honza, your resources really helped me. I fixed the problem.

Rather than emulate UI actions, you might also be able to use eval or CommandLine.evaluate (the latter if you need support for command line API, evaluating code in debugger frames, etc., but it's a more complex API).

[Ebrahim]

It would be nice if I can use these functions. I tried this function:

Firebug.Debugger.evaluate(expr, context, scope); //  thisValue : null

but does not work for me. I also could not find the eval function.

What error is thrown? Are you sure you want to use Firebug.Debugger.evaluate? It should only work when stopped in the debugger, I believe. As a proof-of-concept with CommandLine.evaluate, you can evaluate the following in a chrome-scope scratchpad, with Firebug open:

        Firebug.CommandLine.evaluate("1+1", Firebug.currentContext, null, null, function(res) { alert("result: " + res); }, function failure() { /* won't happen */ });

(obviously, in real code, "1+1" and Firebug.currentContext would be more generic, the second null parameter might be a specific window).

With eval I mean the window.eval function built into the JavaScript language - try e.g. content.eval("1+1") in a scratchpad.

[Ebrahim]

Thanks Simon. I tried this function for some scripts and it works as I need. In my case, the expression to be evaluated is a bit complicated (scripts for user simulation purposes), but I expect no problem. 

Thanks again,

Ebrahim

it's also useful for my question, thank you! but i'm not clear about the Firebug.currentContext, can you help me?

Firebug.currentContext represents the data shared within Firebug. It is the context Firebug is running in.

I have noticed something strange. I use the following command to simulate click event of a radio button in my Firebug extension:

targetClickableElement.setAttribute('data-id','1'); //targetClickableElement is a radio button element

var str =  "var element = jQuery('[data-id=1]',document).get(0);"+"\n";

str = str + "jQuery(element).trigger('click');";

Firebug.CommandLine.evaluate(str, Firebug.currentContext, null, null, function(res) {}, function failure() { /* won't happen */ });

It works for some Websites (e.g., http://www.dressbydesign.com/dress/design) but not for all (e.g., http://www.mydogtag.com/#).

Obvious guess: the second page doesn't have jQuery.
