Question

I’m trying to replace every multiline import inside a Python source file.. So, the source goes like

from XXX import (    AAA,    BBB, ) from YYY import (    CCC,    DDD,    EEE,    ... ) ...other instructions... 

and I’d like to get something like

from XXX import AAA, BBB from YYY import CCC, DDD, EEE, ... ...other instructions... 

I tried to use sed but it looks like it doesn’t support non-greedy matching of the closing parenthesis, so it ‘eats’ the second import.. 🙁
Any hint? Is this impossible with sed? Should I try with another tool?

Ummm… what’s wrong with Python?

lineIter= iter(aFile) for aLine in lineIter:     if aLine.startswith('import'):         if aLine.endswith('('):             for aModule in lineIter:                 if aModule.endwith(')'):                     break                 print 'import', aModule.strip()         else:             print aLine.stri()     else:         print aLine.strip()
