Removing text from parenthesis on

[Howard]

Here is an input sample:

Arizona (5)

Minnesota (4)

Cleveland (2)

San Diego (4)

Using Grep, I want to remove all the text in each item from the left parenthesis on. How can I do that?

[Jean-Christophe Helary]

including the left parenthesis:
search for \(.+$
replace with nothing

excluding the left parenthesis:
search for (?<=\().+$
replace with nothing

The "exclusion" uses a "lookbehind" match as in "look behind this to see if the rest matches, but only act on the rest". So here, it says "look behind a left parenthesis see if you find anything"

What if I wanted to extract all the text up to, but not including, the left parenthesis?

Then you need to check that the left parenthesis is ahead of the stuff you need to match. So it's a "lookahead is there's a left parens!":

^.+(?=\()

And if you want to *extract* the stuff that matches, you have a cute "Extract" button in the Search dialog to do that.

The manual is of tremendous help too.

search for 

\(.*

and replace it with nothing.

You may want to add a space before it if you want to exclude the space

That is quite an easy way to do it. Thanks.
