I happened to stumble upon Guido's announcement of his python2 to python3 refactoring tool earlier today (http://mail.python.org/pipermail/python-3000/2006-December/005102.html), and, after playing with it a bit, I have some use questions as I don't quite understand how the pattern matching language works.
In some instances I cannot grok matching certain sorts of patterns, sometimes very simple ones. For instance, how is the following incorrect for matching pass statements? pass_stmt< 'pass'> If I wanted to insert "# Do nothing, and well." after each pass statement how would the transformation work? Why would this pattern not match function statements? funcdef< decorators < decs=any > 'def' atom < def_name=NAME > parameters < pars=any > ':' suite < suite_content=any > > If I wanted to change the function name how would I do so? How about parts of the function body? -- http://mail.python.org/mailman/listinfo/python-list
