shrink-whitespace.el

shrink-whitespace is a DWIM whitespace removal key for emacs. The behaviour is pretty simple, but I haven't found anything else that does what I want.

Usage

Consider the following scenario, point represented by (|):

Here is some text


(|)



Here is some more text

When you invoke shrink-whitespace, the whitespace between the lines is reduced to a single line like so:

Here is some text
(|)
Here is some more text

If you want to remove further whitespace, just invoke it again:

Here is some text
(|)Here is some more text

Now there is no space between the two lines, and point is at the beginning of the second line.

This same function works with horizontal space, and uses the same general logic. Consider the following scenario:

int main(int argc,     (|) char *argv[])
{

	return 0;
}

Invoking shrink-whitespace removes the extra whitespace around point:

int main(int argc, (|)char *argv[])
{

	return 0;
}

And can be invoked again:

int main(int argc,(|)char *argv[])
{

	return 0;
}

That's really all there is to it, but I find it remarkably useful, and use it every single day.
