From 8af84dadb142f7321ff0ce8690385e99da8ede2f Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sun, 31 Aug 2008 15:50:23 +0200 Subject: git wrapper: DWIM mistyped commands This patch introduces a modified Damerau-Levenshtein algorithm into Git's code base, and uses it with the following penalties to show some similar commands when an unknown command was encountered: swap = 0, insertion = 1, substitution = 2, deletion = 4 A typical output would now look like this: $ git sm git: 'sm' is not a git-command. See 'git --help'. Did you mean one of these? am rm The cut-off is at similarity rating 6, which was empirically determined to give sensible results. As a convenience, if there is only one candidate, Git continues under the assumption that the user mistyped it. Example: $ git reabse WARNING: You called a Git program named 'reabse', which does not exist. Continuing under the assumption that you meant 'rebase' [...] Signed-off-by: Johannes Schindelin Signed-off-by: Alex Riesen Signed-off-by: Junio C Hamano --- Makefile | 2 ++ 1 file changed, 2 insertions(+) (limited to 'Makefile') diff --git a/Makefile b/Makefile index bf400e64f3..3daa6dcdb0 100644 --- a/Makefile +++ b/Makefile @@ -358,6 +358,7 @@ LIB_H += graph.h LIB_H += grep.h LIB_H += hash.h LIB_H += help.h +LIB_H += levenshtein.h LIB_H += list-objects.h LIB_H += ll-merge.h LIB_H += log-tree.h @@ -433,6 +434,7 @@ LIB_OBJS += hash.o LIB_OBJS += help.o LIB_OBJS += ident.o LIB_OBJS += interpolate.o +LIB_OBJS += levenshtein.o LIB_OBJS += list-objects.o LIB_OBJS += ll-merge.o LIB_OBJS += lockfile.o -- cgit v1.2.3
