This is a
playground to test code. It runs a full
Node.js environment and already has all of
npm’s 1,000,000+ packages pre-installed, including
@d4nyll/git-tt with all
npm packages installed. Try it out:
@d4nyll/git-tt lists no main file and has no index.js, so it can't be directly required. If this is a mistake, please let us know. It may however contain internal files that you can require manually:

git tt (short for time travel) is a Git extension that makes it super easy™ for you to commit in the future or the past!
$ git tt -m "Commit in the past" --date "2 weeks ago" $ git tt -m "Commit in the future" --date "3 hours from now"
$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash $ source ~/.bashrc $ nvm install node
After Node.js is installed, install
git tt globally it using npm.
$ npm install --global @d4nyll/git-tt
git tt works in the exact same way as
git commit, apart from the
--date option, which differs in the following ways:
git commit, the
--dateoption allows you to specify the author date, whilst with
git tt, the
--datespecifies both the author date and committer date.
--date, which means you can use date strings like
"yesterday at 20:43"or
"30 minutes from now", as well as the usual RFC 2822, ISO 8601, RFC 3339, and other common formats

Note on timezone -
git ttuses your machine's local timezone (the same behavior as
git commit). When time-travelling,
git ttwill use the timezone that would apply at the time you're travelling to. (Basically, you don't need to care about timezones)
git tt, make sure you have Node.js and the yarn package manager installed. Please use yarn as the primary lock file we use is
Next, clone the repository.
$ cd ~/projects $ git clone firstname.lastname@example.org:d4nyll/git-tt.git
Then, every line of relevant code is defined in
I did not follow test-driven development (TDD) because I was initially just playing around, and was unsure about the interface that
git tt should expose. I will continue to use
git tt in my every day workflow to make sure it's user-friendly, fix any bugs, and once I am happy, the plan is to revisit this and write the unit tests.
To test it manually, run
npm link, which will make the
git tt command available on your shell. Once you've finished testing, run
npm unlink to reset it.
If this tool becomes more popular, or if you'd like to contribute to new features, here are some of the features I have in mind (in order of importance):
--fuzzyflag, add a few seconds/minutes in a random fashion so the dates are not so 'precise'. E.g. instead of
Thu Oct 25 12:00:00 2018 +0100, make it
Thu Oct 25 12:03:56 2018 +0100
