git-novelty

This is a dumb Go binary to create cool Git commit hashes. Once installed, you can sort of use it in place of git commit.

Build Dependencies

• go
• latest libgit2 release
• git2go (go get github.com/libgit2/git2go)

Syntax

git-novelty -m <message> (-p <prefix>|-r <repeat> -c <cycle>)

If git-novelty is in your shell path, you can use:

git novelty -m <message> (-p <prefix>|-r <repeat> -c <cycle>)

Modes

In prefix mode, git-novelty will try to create a commit with a hash that begins with your specified string. For example, git-novelty -m "foo" -p "0123456" might produce this hash: 01234569ba676004aa72a83ed2ce0f61ab663fc5.

In repeat mode, git-novelty will try to create a commit with a hash that has a repeating pattern for each cycle you specify. For example, git-novelty -m "foo" -r "0123" -c 10 might produce this hash: 0123bf19ba012304aa720123d2ce0f0123663fc5.

Caveats

This works by adding in salt to the commit message, kind of like how Bitcoin hashing works. Finding the desired hash can take a very long time, depending on the number of target bytes.

Example

mkdir foo
cd foo
git init
echo foo > foo
git add foo
git commit -m "Initial commit"
echo bar > bar
git add bar
git novelty -m "Added bar" -p "beef"
