We do a lot of lexical processing with arbitrary strings which include arbitrary punctuation. I am divided as to whether to use magic characters/strings or symbolic constants.
The examples should be read as language-independent although most are Java....

For general string processing , I wouldn't use special!):
s.replace("String", " ");
Than:
s.replace("String", S_SPACE);
I would take special care to use things like to deal with constants....

The sample string:
this!is.an?example
I want to match: this is an example.
I tried this:
<script type="text/javascript"> var string="this!is.an?example"; var pattern=/^\W/g; alert(string.match(pattern)); </script>

If you want to split also on underscores, use this:
var words = "this!is.an?example_with|underscore....
Why you want to explicitly match , but if your goal is to strip all punctuation, this would work:
var except letters, digits and underscore.

For the hope-to-have-an-answer-in-30-seconds part of this question, I'm specifically looking for C#
But in the general case, what's the best way to strip punctuation in any language?
I should add: Ideally, the solutions won't require you to enumerate ...

Imagine is a regex.replace and have your regular expression with all the appropriate punctuation marks stripped = input.replaceAll("\\p{P}+", "");
The first version only looks at punctuation characters contained in ASCII.

It seems like there should be a simpler way than:
import string s = "string. With. Punctuation?" # Sample string out = s.translate(string.maketrans("",""), string.punctuation)
Is there?

I'm looking to remove all punctuation from a string and make all uppercase letters lower case in C, any suggestions?

Answer Snippets (Read the full thread at stackoverflow):
Whenever you meet an "alpha char" ( isalpha ), use tolower to convert.
Whenever you meet a punctuation ( ispunct ), don't copy it to the output string.
Loop over the characters of the string.

I'm trying to split a string on its punctuation, but the string may contain URLs (which conveniently has all the typical punctuation marks).
I have a basic working knowledge of RegEx, but not enough to help me out here. This is what I was using when I...

Is there a pattern that your non-URL punctuation marks follow? In most English sentences, many punctuation marks are followed (or sometimes preceeded) by a space character.

I'm trying to split a string up into words and punctuation, adding the punctuation to the list produced by the split.
For instance:
>>> c = "help, me" >>> print c.split() ['help,', 'me']
What I really want the list to look like is:

What I want to do is check for duplicated words right next to each other but even if there is punctuation in between.
For example:
Vivamus Vivamus diam, diam, Vivamus Vivamus diam, diam Vivamus
there should be 4 distinct hits here.
I can't figure out ...

You will need to use for the punctuation, but does include the captured punctuation in the first capture.
The (?: is a non-capturing parenthesis, meaning it won't store the matches .

Any one know a good way to remove punctuation from a field in SQL Server?
I'm thinking
