This is a simple Emacs interface to DXR. While earlier versions relied on a separate dxr executable, this version is standalone.

There are three main ways to use dxr.el:

• dxr-browse-url. This opens a DXR page for the current file and line in a browser window.

• dxr-kill-ring-save. Like dxr-browse-url, but instead of opening the URL, copies it to the kill ring.

• dxr. This runs a DXR query and puts the results into a *grep*-like buffer.

You can install this by checking it out, opening dxr.el, and then running M-x package-install-from-buffer. It is also available in Marmalade.
