- Access any LLDB CLI command in Vim by typing ":L<command>". Tab-completion works too! - See source locations for breakpoints and the current PC with vim "marks" and highlights. - Examine backtraces, locals, disassembly, registers, and breakpoints in dedicated Vim windows. - See when in-scope variables and registers change by watching for (red) highlights. This plugin opens multiple Vim "windows" to display debugger information. To quit all windows at the same time use ":qa". The alternative would be ":q" to close each window separately. This plugin is known to work on Mac OS X (Mountain Lion) with MacVim and the system-provided terminal Vim, and on Linux (Ubuntu 12.04 and 12.10) with GVim and the terminal Vim from the "vim-gnome" package. llvm-svn: 174892
