This is a mirror of http://www.vim.org/scripts/script.php?script_id=2048 This script provides a simple and fast way to see the difference between two blocks of text. This might be similar source code functions, definitions, etc. Just select the first portion, goto Menu "Tools->BlockDiff->This is block 1". Select the second portion, goto Menu "Tools->BlockDiff->This is block 2, start diff". The script will open a new tab, split it and diff the two portions. If you prefer the mouse context-menu, a key mapping or ex commands, they all are prepared in the file, just remove the comment and/or change the mappings. Currently only for Vim 7.* with GUI (and tabs).
