GoGit

GoGit is a cli tool to quickly switch between github profiles/accounts.
Currently only works with very specific SSH config setup (see below).

Disclamer

This tool is under development and can cause corrupt files. Please use with caution!
Before overwriting a file (e.g. ~/.ssh/config or ~/.gitconfig), GoGit will make a copy of the previous file.
This file will have the same name as the original but with .bak appended to the end.
For example .gitconfig => .gitconfig.bak, these files can come in handy to restore the old file when a corrupt file is produced.

Problem

I found it annoying having 3 GitHub accounts at once and having to use special Host values in my SSH config like this:

# Work account (default)
Host github.com
    Hostname github.com
    Port 22
    User git
    IdentityFile ~/.ssh/id_a

Host github.com-personal
    Hostname github.com
    Port 22
    User git
    IdentityFile ~/.ssh/id_b

Host github.com-other
    Hostname github.com
    Port 22
    User git
    IdentityFile ~/.ssh/id_b

And then I had to alter the remote url for each local repo to have the correct permissions to the remote repo:
git remote add origin [email protected]:username/repo.git

After not finding a nice solution for this problem, I figured I could build one as a side project.

Solution

To fix this issue I am building a cli too that can manage my git profiles/accounts for me.
When I arrive at work, I run 1 single command to switch to my work git account and everything is setup as it should.
When I get home, I just switch accounts again with 1 command.

Building

Requirements

• git
• Go 1.20 or up

After cloning the repo, you can build and move the binary bin/gogit to a place in your PATH.
I prefer to use /usr/local/bin/

Build binary

make build

Install on MacOS or Linux
Builds binary and moves it to /usr/local/bin/

make install
sudo make install # if you require root access for /usr/local/bin/

Commands

gogit add <name> <email?> <username?> <remote?>

Add a new git account to the GoGit config with the following arguments:

• name:
  • custom name for profile
• email:
  • (optional) email of your git account
  • default = current email in ~/.gitconfig
• username:
  • (optional) name of your git user
  • default = current name in ~/.gitconfig
• remote:
  • (optional) custom remote name
  • default = github.com

---

gogit set <name>

Set the current active account.

GoGit will only change the Host values in your SSH config. 
For example: github.com-<name> to github.com and back.
All other settings will be left unchanged.

---

gogit init

Create a blank GoGit config file

---

gogit active

See the current active account

---

gogit remove <name>

Remove a profile/account from GoGit, leaves your SSH config untouched.

---

gogit list

Get a list of the current configured profiles/accounts with the arrow -> indication the active one.

profiles:
-> home
-  work
-  other

SSH config

GoGit currently requires you to have your SSH config file setup up in a specific way. This needs to be done manually for now.
See the problem section for an example structure of a working ~/.ssh/config file.

GoGit config file

Located at: ~/gogit.ini

[profiles]
first   = true
second  = false

[preferences]
# enable if you want to auto update your global git config user and email
set-git-user = false

[profile.a]
remote   = github.com
username = User a
email    = [email protected]

[profile.b]
remote   = github.com
username = User b
email    = [email protected]

• Setting set-git-user to true will make GoGit alter your ~/.gitconfig file
• Each profile has unique settings

Features to add

• Option to atuo add new block to ssh config on gogit add
• Add gogit remove command to remove a profile/account
• Add support for other git remotes
• Setting git config --global when activating account
