Git shortcuts for implementing the scalable git branching model

Prerequisites

Powershell Core (7+)
git 2.41+

Installation

Install Powershell tools for macOS

Microsoft has instructions to install PowerShell for macOS. Alternatively, if you already have the latest .NET Runtime installed, you can install PowerShell as a .NET Global tool.

dotnet tool install --global PowerShell

Note: if you have an older version installed, such as .NET 7, you can install an older version of PowerShell.

Install Git Shortcuts

See the above prerequisites.
Clone this repository. If you are working on multiple projects and need specific versions of the tools, clone it once for each project (or use git workspaces).
In your terminal, navigate to the git directory in which you want to use the commands. Then run the init.ps1 from this repository. For example, if this was cloned in C:\Users\Matt\Source\scalable-git-branching-tools and you want to use them in "MyProject", run:
```
 C:\Users\Matt\Source\scalable-git-branching-tools\init.ps1
```
Relative paths work, too. To clone and run, you may use the following commands:
```
 git clone https://github.com/PrincipleStudios/scalable-git-branching-tools.git ../scalable-git-branching-tools
 ../scalable-git-branching-tools/init.ps1
```

Commands

git show-downstream

git refactor-upstream

git release

Development

Tests

Install the latest version of Pester:

Install-Module Pester -Force
Import-Module Pester -PassThru

From the git-tools folder, run:

Invoke-Pester

There are also docker integration tests that actually run the git commands; run:

docker build .

Note that, due to the use of Import-Module, PowerShell caches scripts in the local environment. This won't affect users when updating, since each git alias launches a new pwsh scope. However, for developers, you can use the following command to pick up changes in any .psm1 files within this project:

./reset.ps1

Demo

If you want to test it locally, but don't have a git repository set up, you can use one of the samples via Docker! Run one of the following:

docker build . -t git-tools-demo -f Dockerfile.demo
docker build . -t git-tools-demo -f Dockerfile.demo --build-arg demo=local
docker build . -t git-tools-demo -f Dockerfile.demo --build-arg demo=remote-release
docker build . -t git-tools-demo -f Dockerfile.demo --build-arg demo=remote-without-config
docker build . -t git-tools-demo -f Dockerfile.demo --build-arg demo=remote
# build arg matches ./demos/demo-<arg>.ps1

Then take the resulting image SHA hash and run:

docker run --rm -ti git-tools-demo

This will give you a PowerShell prompt in the repos directory; cd local and try out the commands!
