[Pythoncard-users] PythonCard, Eclipse and Pydev

[Don T. <nos...@ca...>]

Total Newbie question - I have not yet tried PythonCard or wxWidgets but 
I will 'real soon now'.

I presume that I can use Eclipse+Pydev for my Python editing while using 
Pythoncard to edit my resources.  My question is can I run and debug a 
PythonCard application from within Eclipse+Pydev?

I know that I can try this out myself (and I will) but has anyone else 
tried this, or something like it, and what pitfalls I should look out for.

Thanks,

Don.

Sorry, I haven't tried Eclipse.

I use the PythonCard editor about 90% of the time - does have some 
advantages for having built-in knowledge of the controls and events 
associated with them, plus easy access to the runtime options (debug, 
log, message watcher, etc.)

When I have complex changes to do, I use Emacs for the sake of its 
macros etc. (and out of long-term habit).

The other 5% of the time, when I want a serious debugger, I use Wing-IDE 
(Personal Edition).

I been able to use Eclipse/Pydev on "Minimal" and the debugger seems to 
work at least in a very simple set up.  Eclipse/Pydev and the 
resourceEditor seem to play quite nicely togtether.  If the resource 
files has a different extention then I could register the resourceEditor 
as an external editor on Eclipse.

I am curious about the PythonCard editor having "built-in knowledge of 
the controls and events associated with them".  A quick look at the code 
editor did not reveal this to me - what should I be looking for?

I plan to experiment further with Eclipse/Pydev - PythonCard as it seems 
like a nice combination to me.

Thanks,

Don

It's not in the "normal" codeEditor, it's in the "advanced" version, 
which can be found, rather confusingly, in
  PythonCard/tools/oneEditor/tabcodeEditor.py

Has two features not in the basic editor
 - uses tabbed notebook to allow multiple files to be edited
 - has a drop-down for all controls in the current file
       Selecting one of them makes another drop-down appear.
       This shows all events for that control type, with a "+" marking 
those for which a handler exists.

Selecting one of those will position the cursor on the first line of the 
handler.
Selecting one for which no handler exists yet will insert a "blank" handler
               (without ensuring your on a blank line - use with care :-)

This "advanced" editor is "experimental" - hasn't been as widely used or 
tested as the basic one, so use with care. Having said that, I've used 
it almost exclusively for many months and had only one (repeated) glitch 
(something to do with opening new windows while the shell window is open 
- but couldn't reproduce it).

Oh - and it doesn't yet do Ctrl-F4 to close a tab - you need to do 
Ctrl-W. Minor, but annoying.

Oh, this looks very handy indeed.  Thanks.

What about a facility for adding background event handlers too?  I 
initialize mentioned in a tutorial, but I can't find a refernce to any 
others.

They aren't used all that often (or at least, I don't use them that often).

They aren't true "background" handlers in the Hypercard sense, so you 
need to be careful (though given that I've never used Hypercard, my 
interpretation may be slightly off ....)

You can create a handler, say on_mouseMove. If there is a component 
which could have had a mouseMove handler, but doesn't, then those events 
go to the "background" handler instead. But there is no mouseMove event 
generated when the mouse is moved while not over any component, nor 
while over a component that doesn't support mouseMove.

Since the code inserted is so minimal, I'm not sure it's worth adding a 
method to insert background handlers - easy enough to do manually, or to 
add a handler to a component and remove the component name (i.e. edit 
"on_someComponent_event" to be just "on_event")

I tried this last night and it seemed to work quite nicely - at least 
for the few minutes that I played with the 'minimal' app simultaneously 
in both Eclipse/Pydev and the resource editor.  I was able to run the 
Pydev debugger on minimal and it looked OK.  Eclipse recognized when a 
file it was editing changed on the file system and offered to reload it.

More play to day.

Don.

(FWIW.  The main reason I like Eclipse is because of its local history 
feature, I don't think that I want to live without it.  You can safely 
bash away at some source and save it multiple times knowing that you can 
always go back to a working version without having to remember what you 
need to do to undo the changes.  It is like having a local version 
control system that automatically commits your changes whenever you save 
  a file.  I don't know if other editors/IDEs have this feature.)
