In python I can write:
myregex = r’\sAnd\s’
s = re.sub(myregex,’ & ',‘Bake Beans And spam.txt’)
print s ## prints: Bake Beans & spam.txt
However using:
var = self.AdvanceReplace.GetValue()
f is filename: Bake Beans And spam.txt
TextCtrl contains r’\sAnd\s’
print var # Bake Beans And spam.txt
s = re.sub(var,’ & ',f)
print s # Bake Beans And spam.txt
How can I use my box to accept an regex?
Wow, this reads like a koan.
If you want to get a string from a wxTextCtrl, then using the .GetValue() method will, yes, in fact return a string. Then you can do whatever you want with that string.
I beg-to-differ
Here is my complete code. Add a folder with a text called “Bake Beans Amd spam.txt”
The bottom TextCtrl you can add an regex. r’\sAnd\s’
You will see that the regex will not accept the first agument as a string!

I even used Tim Roberts suggestion and got the same results.

Use meaningful names for controls, methods, variables etc and it will help you.
Your first sample is better:
s = re.sub(myregex,' & ','Bake Beans And spam.txt')
so change that to:
s = re.sub(myregex, ' & ', filename)
And use a debugger to step through your code and make sure that the variables really contain what you think they contain.
var = self.AdvanceReplace.GetValue()
print var, " print v"
s = re.sub(var,' & ',f)
print s, " print s"
In your full script you have the above, verify with the debugger that at this point "var" contains "r'\sAnd\s'"

I doubt that this is your problem.
But frankly I can't follow this thread anymore - what are your comments above relate to? Please use interspersed format, i.e. put the relevant comment below the text you are commenting on and maybe this way we get a bit further.
I suggest you create a small runnable application which just has hard coded the above values - i.e. not be dependend on some file on disk or whatever.

Hi,
I confess, I am almost lost in the code as well as in the further
comments, but just in case it could be the issue here:
the raw string form like:
r'\sAnd\s'
is meant to be used in the source code - apostrophes to delimit
string, r-prefix the avoid special evaluation of backslash (or you can
use '\\sAnd\\s' .
In the gui textcontrol like wx.TextCtrl the above would be displayed just as
\sAnd\s
and the GetValue call will return the same pattern string.

I adjusted your sample to relate to my problem. Enter a regex in the second TextCtrl and you will see that
that self.regEx = wx.TextCtrl is not passing a regex function. The user enters regex.
I hope this states my problem better.

What exactly is being entered into the TextCtrl?
I hope this states my problem better.
I didn't know how to do that but reading the earlier post of Vlastimil gave me the hint.
So attached a modified version which works for me.

There is no such thing as a "regex function". A regular expression is
just a string that happens to use some special characters. That string
gets passed to the re.sub function, which processes it.
Your sample code also works just fine. If I type \sAnd\s in the box,
the substitution happens. So, what is the problem?
By the way, this is silly:
c = Sample(None)
with c as dlg:
dlg.ShowModal()
The whole point of the "with" block is ti make sure the object doesn't
exist when the "with" is completed. You should just do this:
with Sample(None) as dlg:
dlg.ShowModal()
(Although my version of wx doesn't support that yet.)

Great that things work for you now.
Obviously much nicer, in my “defense” this is a copy/paste thingy where I didn’t
think much, in my case the code is normally:
c = Sample(None)
… do other stuff to init this thing
with c.view as dlg:
dlg.ShowModal()
I think the “with” context manager support for Dialog etc has been
added as of 2.8.11.0 - a loooooooooooong time ago.

Then I just missed it – I have 2.8.10.1. wx is not part of my
