thx for that. I had a file called 'tktest.py' lying around, and I did:
'>>> a = compiler.parseFile('tktest.py')
And "a" looks something like this:
***
Stmt([Import([('Tkinter', None)]), Function(None, 'add_rows', ['w',
'titles', 'rows'], [], 0, None, Stmt([Discard(CallFunc(Getattr(Name('w'),
'configure'), [Keyword('state', Const('normal'))], None, None)),
For(AssName('r', 'OP_ASSIGN'), Name('rows'),
Stmt([For(AssTuple([AssName('t', 'OP_ASSIGN'), AssName('v',
'OP_ASSIGN')]), CallFunc(Name('zip'), [Name('titles'), Name('r')], None,
None), Stmt([Discard(CallFunc(Getattr(Name('w'), 'insert'), [Const('end'),
Mod((Const('%s:\t%s\n'), Tuple([Name('t'), Name('v')])))], None, None))]),
None), Discard(CallFunc(Getattr(Name('w'), 'insert'), [Const('end'),
Const('\n')], None, None))]), None), Discard(CallFunc(Getattr(Name('w'),
'configure'), [Keyword('state', Const('disabled'))], None, None))])),
Assign([AssName('app', 'OP_ASSIGN')], CallFunc(Getattr(Name('Tkinter'),
'Tk'), [], None, None)), Assign([AssName('t', 'OP_ASSIGN')],
CallFunc(Getattr(Name('Tkinter'), 'Text'), [Name('app'), Keyword('state',
Const('disabled'))], None, None)), Discard(CallFunc(Getattr(Name('t'),
'pack'), [], None, None)), Assign([AssName('info', 'OP_ASSIGN')],
List([List([Const('Ali'), Const(18)]), List([Const('Zainab'), Const(16)]),
List([Const('Khalid'), Const(18)])])), Discard(CallFunc(Name('add_rows'),
[Name('t'), List([Const('Name'), Const('Age')]), Name('info')], None,
None)), Discard(CallFunc(Getattr(Name('app'), 'mainloop'), [], None,
None))])
***
Pretty impressive :)
Do you know of more batteries that can process this stuff further, for
interest sake (and maybe the OP)?
thx again
