Git Crypto

Nobody asked or wanted this Curse.

How this Curse came into existence

So last night at about 3am I was part of a discussion on discord about git, at teh same time there was another discussion in a different channel about crypto.
So our git discussion got tainted with stuff like:

Person 1: git burn evidence
...
Person 2: something something git isn't a real blockchain because you can do that
Person 2: or conversely, blockchains are just worse git

Person 3: blockckain based source control

As it turns out it is pretty easy to create sub commands for git so I did the normal thing and start thinking up of ~~cursed~~ implementations for git crypto.

Just think about it, git already has hashes and local and remote copies (wallets?) so it only needs a few more tweaks to make it properly crypto!

Cast the Curse

Go to:
- Windows: C:\Program Files\Git\mingw64\libexec\git-core
- Linux: Any $PATH location such as /usr/bin
Make a file called git-crypto there.
Paste in the contents below.
On linux you may need to make it executable.


#!/bin/sh

# mostly taken from https://blog.sebastian-daschner.com/entries/custom-git-subcommands
# assumes a remote named origin

# get the current branch
branch=$(git symbolic-ref -q HEAD | sed -e 's|^refs/heads/||')

# got to record every transaction
git add --all
git commit -m "HODL"
# make sure you are up to date with transactions other have done
git pull --rebase origin ${branch}
# send your transactions off
git push origin ${branch}

Now you should be freely able to use git crypto to shove everything that you did locally into the cloud.

Intensify the Curse

The above is a good start but it isn't fully blockchain yet, it is still mutable.

Person 4: Ironman git, no resets to make it true Blockchain

Thankfully on *nix this can be rectified.
To your ~/.<shell>rc file add the following lines to make your wallet secure.


# from https://stackoverflow.com/a/25886149/11964934

git() {
    if [[ "$1" = "revert" || "$1" = "reset" || "$1" =  "rebase"]]; then
        printf "No 'git %s' Only HODL.\n" "$1";
    else
      # catch sneaky amends
      if [ "$2" = "--amend" ]; then
            printf "No 'git %s' Only HODL.\n" "$1";
        else
            command git "$@";
        fi
    fi;
}

Dispel the Curse

Delete git-crypto.
Remove the override from ~/.<shell>rc.
Disinfect your keyboard/screen.
Donate to mental health services.
Heal your soul:
