Sharefix

Sharefix (GitHub: samiconductor / vim-sharefix, License: MIT) by Sam Simmons makes it easier to work with multiple quickfix lists. If you're running unit tests and getting a list of failing tests in your quickfix list, then it can be annoying when another command overwrites it. This plugin helps make quickfix commands work together.

Once installed, a Sharefix function is exposed that can be used to wrap commands or functions that update the quickfix list. The author has included documentation and usage examples.

GDBFromVim

GDBFromVim (GitHub: skibyte / gdb-from-vim, License: GPL2) by Fernando Castillo provides gdb integration that automatically starts and manages a gdb instance. It requires Python and Gdb lib, and provides lots of commands for interacting with the debugger, like GdbFromVimRun and GdbFromVimNext.

The g:gdb_from_vim_app variable controls which application will be debugged, and arguments can be passed with g:gdb_from_vim_args.
