From 52e9578985fb636ec1d3f6cf794fdadd5ec896fc Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sat, 21 May 2005 02:40:01 -0700 Subject: [PATCH] Introducing software archaeologist's tool "pickaxe". This steals the "pickaxe" feature from JIT and make it available to the bare Plumbing layer. From the command line, the user gives a string he is intersted in. Using the diff-core infrastructure previously introduced, it filters the differences to limit the output only to the diffs between and where the string appears only in one but not in the other. For example: $ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M would show the diffs that touch the string "diff-tree-helper". In real software-archaeologist application, you would typically look for a few to several lines of code and see where that code came from. The "pickaxe" module runs after "rename/copy detection" module, so it even crosses the file rename boundary, as the above example demonstrates.
