git wrapper: DWIM mistyped commands
Subsystems (2)
PATCH 1/1 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' [...]
---
So I mistyped 'reabse' for the hundred trillionth time, but I will never have to correct my mistakes again.
Note: this patch is _not_ meant for inclusion.

Or use a decent shell:
When typing e.g.: git tsa<tab>, it yields:
$ git status
---- corrections (errors 1)
status -- show working-tree's status
tag -- create tag object signed with GPG
tar-tree -- create tar archive of the files in the named tree
---- original
tsa
and it even works for non git commands ;)
</SCNR>
Despite that, I really like your idea. **hint hint** One could even hook that for long options into parse-options.

Oh, that would make me suspicios (and I hit Ctrl-C fast when I get suspicios about what happens to my precious data). Could it be configurable? For example, BASH's cdspell is configurable and even off by default.
P.S. I'm still using your first patch and am forced to like it every day :)

In that case, you need to put in the "one of these" / "this" conditional again, which I ripped out because I do not need it any more.

This "if" already checks if there is only one candidate. So you should just add an inner "if (autocorrect) ... else single = 1;" or some such.
However, I think that the intention of this patch is too much DWIMery, which might be good for me (just like my "git add remote" patch), but not for the general audience.

Please make autocorrect not a binary but optionally the number of deciseconds before it continues, so that I have a chance to hit ^C ;-)

Mustn't be good for all (for the "general audience" it is even common practice to forget to thank. It may be even a sign of bad manners for it). It is good for me though. And thanks for sharing.
Moved git_config before the calls where current directory is changed:
so that it has the same filesystem context as in normal case. Less surprises.

Yes. So check cnt > 0 && best_similarity > 5 says if it is 0, and cnt > 1 && best_similarity < similarity(...[1]...) says if it is 1.
