Python could easily process the escape codes for any given terminal; but, in general, you would want something that works for more then a single terminal type. This means that you need something that can do a reverse translation of the termcap/terminfo database. What you might be able to do, is build a dictionary by querying all of the possible termcap/terminfo functionalities using tgetstr(). Then when you encounter an escape sequence, you can use the escape sequence from the dictionary as a template to parse the sequence. > str = ''aaaa\x1B[K\x1B[D\x1B[D\x1B[D\x1B[D\x1B[C\x1B[C\x1B[C\x1B[C > \x1b[d\x1b[d\x...@q\x1b[@q\x...@q'' > > as a result of printing it (print str), the console's output is as > follows: > > aaqqqaa Your example is rather simplified. Terminal escape coding can get rather complex. Paul Williams of vt100.net has some information on writing terminal emulators at: http://www.vt100.net/emu/ > Having such string with the escape codes I would like to call a > function that would process the input and return the "aaqqqaa" string. > Of course I'm aware that any information about colors will be missed. > I'm wondering if the curses module has such functionality. Not that I am aware of. There are a couple of terminal emulation libraries around that you might want to take a look at. I don't know of any that currently provide Python interfaces; but, they shouldn't be too difficult to interface using something like SWIG. -- http://mail.python.org/mailman/listinfo/python-list
