removing parenthesis
kurtz.kevin
I am not a programmer... I am just trying to remove all the instances
of parenthesis in my text. I have text that is littered with all
variations of parenthesis that I must remove.
How can textwrangler use a wildcard to find opening+anything+closing
parenthesis and delete every instance
for example...
"and the goat said to the frog (jn.3:1) that the worst..."
"in the historical instance of placards (da carson, bigtitle, p.387)
the..."
I just want all these parenthesis-es removed.
Please help!

Do you want to just remove the actual parenthesis characters, or
the text between them as well?

The 'give a man a fish' answer:
Assuming that you want to delete the text between open and close
parens, do a Find (Search -> Find...) and enable the Grep
checkbox in the Find dialog. In the Find box, enter
\(.*\)
Leave the Replace box empty (i.e. replace with an empty string).
Click Replace All. Depending on your exact needs, you might need
to adjust it, but this is the quick and dirty solution.
The 'teach a man to fish' answer:
Read the chapter in the TW user manual on Searching With GREP.

This may not be quite what you want, because it will gobble up everything on a line between ( and ).
To get rid only of the parentheses and their contents you should use a "non-greedy" search: replace \(.*?\) with empty using grep.
If those parentheses are stretching over line boundaries, you might use \([^)]*\).
If you have nested parentheses, you have to use a more complicated approach...

Here I fully agree!

I'm not quite sure what you want to accomplish. Basically, the search you're looking for should be
\[[^\]]*\]
(with [^\]] not [^\)], because you're looking for a closing ]).
But if you have examples where the brackets are not closed properly, or if brackets are nested within each other, you have to decide what that means and what you have to do.

1. xyz = find xyz --anywhere within a line
2. ^xyz = find xyz --but only at the beginning of a line
3. [xyz] = find x OR y OR z --but NOT ] or [, of course
4. [^xyz] = find anything that's NOT x or y or z
5. [^xzy]* = find a run of characters that doesn't include x, y, or z
Notice that the addition of ^ means either "start of line" OR "none of
the following", depending on where the ^ is placed. Notice also that
the brackets above are used for grouping, and not as part of the
match. Therefore to find ] itself we add a backslash:
6. \] = find ]
Putting these together, one at a time:
\] = find a bracket
[^\]] = find NOT a bracket (i.e. anything else)
[^\]]* = find any number of not-brackets
\[[^\]]*\] = find [ plus some not-brackets plus ]
This pattern is a little tricky to understand because it uses brackets
in two different ways: for grouping AND to match a literal right-
bracket. Replacing \] with x allows one to more easily see the
structure:
x[^x]*x
In other words, we're looking for x, followed by any amount of "not
x", followed by x.
And now to your second question. Since, like square brackets, the
asterisk has a special meaning in Grep, finding it requires a backslash:
\*
And so we apply what we learned above to find it at the beginning of a
line:
^\*
I hope this helps.

Hannes, here's a breakdown. In a search pattern:
1. xyz = find xyz --anywhere within a line
2. ^xyz = find xyz --but only at the beginning of a line
3. [xyz] = find x OR y OR z --but NOT ] or [, of course
4. [^xyz] = find anything that's NOT x or y or z
5. [^xzy]* = find a run of characters that doesn't include x, y, or z
Notice that the addition of ^ means either "start of line" OR "none of the following", depending on where the ^ is placed. Notice also that the brackets above are used for grouping, and not as part of the match. Therefore to find ] itself we add a backslash:
