Title: Windows 11: Constructing a "commit-msg" hook using Go application
In this article, we will discuss how to construct a "commit-msg" hook for Windows 11 repositories using a Go application. This hook will be used to perform custom actions whenever a commit message is created or modified.
Prerequisites
Before getting started, ensure you have the following prerequisites:
-
Installed Go (Golang) on your Windows 11 system. You can download it from the official Go website: https://golang.org/dl/
-
Basic understanding of the Go programming language.
Creating the Go Application
First, create a new directory for your project:
mkdir commit-msg-hook
cd commit-msg-hook
Next, create a new Go file named commit-msg-hook.go:
touch commit-msg-hook.go
Open the file in your favorite text editor or IDE and write the following code:
package main
import (
"fmt"
"os"
"bufio"
"strings"
)
func main() {
if len(os.Args) != 3 {
fmt.Println("Usage: git-commit-msg <msg> <file>")
os.Exit(1)
}
msg := os.Args[1]
file := os.Args[2]
// Your custom logic here
err := os.WriteFile(file, []byte(msg), 0644)
if err != nil {
fmt.Println("Error writing file:", err)
os.Exit(1)
}
}
This simple Go application takes two arguments: the commit message and the file path to write the message. You can replace the commented-out section with your custom logic.
Setting Up the Git Hook
Now, copy the Go application executable to the Git hooks directory:
go build -o commit-msg.exe commit-msg-hook.go
cd ..
mkdir .git
cd .git/hooks
ln -s ../commit-msg-hook/commit-msg.exe commit-msg
This creates a symbolic link named commit-msg that points to the Go application executable.
Testing the Hook
Commit a new message and verify that the hook is working:
git config --local core.hooksPath .git/hooks
git commit -m "Test commit"
If everything is set up correctly, you should see your custom logic executed whenever you commit a message.
Summary
In this article, we learned how to create a custom "commit-msg" hook for Windows 11 repositories using a Go application. We discussed the prerequisites, created the Go application, set up the Git hook, and tested the hook.
