What is Alleyoop?
Alleyoop is a graphical front-end to the increasingly popular Valgrind memory checker for the x86 and x86_64 flavors of Linux using the Gtk+ widget set and other GNOME libraries for the X-Windows environment.
Features include a right-click context menu to intelligently suppress errors or launch an editor on the source file/jumping to the exact line of the error condition. A searchbar at the top of the viewer can be used to limit the viewable errors to those that match the regex criteria entered. Also included is a fully functional Suppressions editor.
