How To Remove Indents From Code?

Lets consider this example of code... Don't look at code, but at indents.

        protected function _hashPassword( $password, $salt, $nuts = '' ) {

            if ( $nuts === '' ) {
                $nuts = Kohana::config( 'a11n' )->nuts;
            }


            $password =
                sha1(
                    $password
                    . $salt
                    . $nuts
                );


            return $password;

        }

It's taken from much bigger source code. As you can se开发者_如何转开发e, it's indented by 2 tabs. I want to somehow remove indent from it without using typing. Somehow.

If I use in-editor build-in 'Replace' function and remove those two tabs like...

I get something like this (not in all cases, but almost)...

protected function _hashPassword( $password, $salt, $nuts = '' ) {

    if ( $nuts === '' ) {
$nuts = Kohana::config( 'a11n' )->nuts;
    }


    $password =
sha1(
    $password
    . $salt
    . $nuts
);


    return $password;

}

It's because there are more than only two tabs on one line and it replaces all 4 tabs.

I'm looking for regular expression that's powerful enough to remove indent nicely! Maybe there are any other solutions? Just don't suggest to write code without indents!

Select the code in your favorite modern editor, and hit Shift+Tab.

Surely you want to simply replace ^\t\t, or use whatever character your editor has for the start-of-line anchor if it's not ^ (I have no idea what the capabilities of your particular editor are, only a (pretty good) understanding of how most regular expression engines are driven).

This will only replace two-tab items at the start of each line.

For example, if I were doing this from the command line under Linux,

sed 's/^\t\t//g' oldfile.c >newfile.c

would do what you desire.

Using regular expressions, replace ^\t\t with the empty string. Without using regular expressions, simply replace \n\t\t with \n. Also consider using a source code formatter.

The following applies to Notepad++:

1) Set search mode to: Regular expression

2) Find what: ^[\t]+

3) Replace with:

Edit: This will replace 1 or more tabs from the beginning of every line.

Alternative method: select the whole source code and hit Shift-Tab multiple times. It will remove the tabs from the beginning of every line, just like the regex above. I hope this helps!
