# [TOY PATCH] diffcore-rename: replace basename_same() heuristics by levenshtein 1 messages from 2009-01-02 to 2009-01-02. Participants: Johannes Schindelin. Thread: https://gitlist.dev/t/16966 ## Johannes Schindelin, 2009-01-02 18:07 Subject: [TOY PATCH] diffcore-rename: replace basename_same() heuristics by levenshtein Message-ID: URL: https://gitlist.dev/e/alpine.DEB.1.00.0901021301560.27818%40racer ``` When the environment variable GIT_USE_LEVENSHTEIN is set, the rename score is reduced by the Damerau-Levenshtein distance. This should lead to a little more intuitive rename scores. Signed-off-by: Johannes Schindelin --- I have this in my personal tree, but I did not really use it. Maybe others want to play with it. diffcore-rename.c | 5 ++++- 1 files changed, 4 insertions(+), 1 deletions(-) diff --git a/diffcore-rename.c b/diffcore-rename.c index 168a95b..1f4b371 100644 --- a/diffcore-rename.c +++ b/diffcore-rename.c @@ -5,6 +5,7 @@ #include "diff.h" #include "diffcore.h" #include "hash.h" +#include "levenshtein.h" /* Table of rename/copy destinations */ @@ -187,7 +188,9 @@ static int estimate_similarity(struct diff_filespec *src, if (!dst->size) score = 0; /* should not happen */ else - score = (int)(src_copied * MAX_SCORE / max_size); + score = (int)(src_copied * MAX_SCORE / max_size) + - (getenv("GIT_USE_LEVENSHTEIN") ? + levenshtein(src->path, dst->path, 1, 1, 1, 1) : 0); return score; } -- 1.6.1.rc3.224.g95ac9 ```
