2: Using functions instead of strings as the replacement in sub(). If
you're looking to do a fair amount of conditional logic in your replacement,
it might be more easily written by having a function do it, rather than
attempt to do it all with a regex.
Does the couple replace.py + fixes.py allow me to use own functions in
replacements? I don't want to lose the comfort of replace.py, it is well
As far as I can tell from looking at the code, the replacement is done by
replaceExcept() in textlib.py, and the documentation there clearly states
that you can use a function for replacing (there's a check if the
replacement is a callable function, and if it is that function is called,
thus working the same way as re.sub() does).
The documentation in replace.py states that both parts of the tuple for
replacement must be a string, which appears to contradict textlib.py, but I
think that might be a bug. While I haven't tested this, it appears to me
that writing a function and referring to that should work. Of course you'd
have to test it to be sure.
