I'll show you what I want to do using a textmate command or bundle:
Lets say we have the following document:
foo
diddy
bah
foo
foobah
diddy
I want to find and delete all the lines matching bah, the desired ouput in this case would be:
foo
diddy
foo
diddy
Thanks!
With the document you want to filter open,
Cmd-F to bring up the Finder window
Next, below the two text-entry boxes, click Regular Expression
In the Find text box, type in this regexp (without the spaces):
^ . * ? bah . * ? $
In the Replace text box, do not type in anything--make sure it blank, i.e., no whitespace characters
With the cursor at the beginning of the document you want to filter, click one of the buttons at the bottom of the Find Window--e.g., Replace All to remove all of the matching lines in one step, or Replace and Find to step through the lines one at a time
That's it.
Here's a more automated way to do the same thing:
from the Menu Bar, select Filter Through Command from the Text pull-down menu
enter this into the text box at the top of the small window that appears:
sed ' / ^ . * bah . * $ / d '
select Document as Input and select Replace Document as Output
Click Execute
[Note: i inserted spaces between the regexp tokens in both examples because for some reason the asterisks '' were not rendering in HTML page]
