bigsqrt - Python vs Pike

[Skaperen]

emacs is the only editor i know (besides tools like sed) and it has don untabify wrong before so i want to avoid that.

i tried that code:

Output:
lt1/forums /home/forums 6> py3 untab.py bigsqrt.py fixed.py
Traceback (most recent call last):

    for line in source:

    return codecs.ascii_decode(input, self.errors)[0]

lt1/forums /home/forums 7> cat untab.py
def main():
    from sys import argv
    fn = argv[1]
    tf = argv[2]
    with open(fn, 'r') as source:
        with open(tf, 'w') as out:
            for line in source:
                if line.startswith('\t'):
                    line = ' '*4 + line[1:]
                print(line, end='', file=out)
    return

main()

google tells me about the GNU expand command which i found is already in Ubuntu 16.04.1 LTS :)  it seems to work so i will attach the fixed file.  the attach system here does not like .pike so an untabify of that is not attached.
