inspect: get the calling command (solved)

[Hans Georg Krauthaeuser]

I got a working solution by myself:

import inspect

def call(a,b,c,d,e):
     s = inspector()
     return s

def inspector():
     frame = inspect.currentframe()
     outerframes = inspect.getouterframes(frame)
     ccframe = outerframes[2][0]
     ccmodule = inspect.getmodule(ccframe)
     try:
         slines, start = inspect.getsourcelines(ccmodule)
     except IOError:
         clen = 10
     else:
         clen = len(slines)
     finfo = inspect.getframeinfo(ccframe, clen)
     theindex = finfo[4]
     lines = finfo[3]
     theline = lines[theindex]
     cmd = theline
     for i in range(theindex-1, 0, -1):
         line = lines[i]
         try:
             compile (cmd.lstrip(), '<string>', 'exec')
         except SyntaxError:
             cmd = line + cmd
         else:
             break
     return cmd

if __name__ == '__main__':
     s1 = call (1,2,3,4,5)
     s2 = call (1,\
                2,\
                3,\
                4,\
                5)
     print '-'*10
     print s1
     print '-'*10
     print s2
     print '-'*10
