many comments like this:

There's also patience diff[1], which does a better job in some situations[2]

Fyi... a related wiki page about LCS (Longest Common Subsequence) with more diagrams and pseudocode: https://en.wikipedia.org/wiki/Longest_common_subsequence_pro...

I don't understand why there isn't a better code-aware diff tool available, like an AST diff

I strongly encourage people to read about the lesser-known Tichy diff algorithm too: https://bryanpendleton.blogspot.com/2010/04/more-study-of-di...

Any in-depth article on string diffs should mention alignment algorithms such as Smith Waterman [1]

..would love to see just one of these people actually implement diff.

After a little while, you start to get pretty comfortable with the snake notion, though my wife still doesn't want me extending any maximal snakes around the house[/i]![i]

TERRIBLE!
