doCommand() bug?

[Phil]

In an @button node I have the following text:

      c.doCommand(c.copyOutline, label='Copy Node')

When I click the button, I get the error below:

exception executing script
TypeError: doCommand() got an unexpected keyword argument 'label'

--------------------
  line 2: #@+node:phil.20200202134614.6: * @button Copy Node
* line 3: c.doCommand(c.copyOutline, label='Copy Node')
  line 4: #@-leo
  line 5: 

I am running this:

Leo 6.6b2-devel, devel branch, build f85969ae8c
2021-12-21 06:16:01 -0600
Python 3.7.3, PyQt version 5.12.4

Did this work in the past?  The call signature doesn't match your usage.  Here is the signature of doCommand, from PyLeoRef -

def doCommand(self, command_func, command_name, event):

You could just call c.copyOutline() directly, without invoking c.doCommand().

It is documented that way here:

So maybe things have changed...

Thanks for this.  I have just removed the discussion of doCommand from the documentation from this section in leoDocs.leo and will update the web docs when I return home.

Leo always catches exceptions, so there is no need to complicate the discussion. The section now discusses only c.executeMinibufferCommand.
