Masked edits?

Jeff_Childers · February 11, 2003, 1:59pm

I would be happy to help with this, if I can. Send me code to test, or send
me what you've got and assign me a function or two.

Regards,

Jeff Childers

What else would we need besides # for digit?

I think it's a good idea to avoid reinventing the wheel.

Actually, considering what I just said, I feel that there
are two natural forms of syntax for edit masks. One is
string formatting, and the other is regular expressions.
Why should programmers have to learn a third way of saying
more or less the same thing?

Rather than: Format='(###)###-####' I would suggest that we
either write Format='(%3i)%3i-%4i' or
Format=r'\(\d\d\d\)\d\d\d-\d\d\d'

I realize that RE and format strings are different from edit
masks, but at least we won't have to invent so much, and
programmers won't have yet another syntax to learn. One could
actually imagine reusing the strptime syntax as well, it fits
with string syntax.

I guess the regular expression syntax is the most versitile
of these though. We have \d for digit and \w for alphanumeric.
If we want to be able to enter floats, we can type
Format = r'-?\d+\.\d*' only letters Format=r'[A-Za-z]*' and
so on.

One thing to consider though: Don't forget that not all people
use US ASCII letters, or decimal points. (Some countries actually
follow the ISO standard...)

I have not been able to put time into this endeavor yet. You can start it if
you wish. I will eventually need this, so I'll end up doing it if it's not
already done by the time I get to it. But for the time being I've been put
on higher priority stuff.

The functions I listed were just to illustrate an idea - the notion was that
you can assign the behavior by calling a function, and leave the format
specs as a parameter. At that time we had people wanting to use RE, I was
concerned with easy formatting of currency, and someone wanted printf
styles. So rather than bicker about which one to use, I wanted to show that
you could use all of them on the same class, and infer the behavior

Also, I'm rather new to Python and wxWindows so I probably won't write the
best code. I'm picking it up quickly though!
