在软件开发过程中，编写清晰且符合规范的 Git 提交信息至关重要。为了提高效率和规范性，可以利用 Ollama 和 PowerShell 脚本自动生成提交信息。本文将介绍如何实现这一功能。
前置条件
git
ollama，并 pull model ， 比如这里使用
codegeex4:latest
1. 添加 PowerShell 函数
执行notepad $PROFILE 添加加以下内容，其中 model codegeex4:latest,你可以改成其它 model （qwen2.5-coder、deepseek-coder-v2），请参考ollama.com/library?q=c… ：
function gco {
# Function to generate commit message
function Generate-CommitMessage {
$diff = git diff --cached
$message = $diff | & ollama run codegeex4:latest "
Below is a diff of all staged changes, coming from the command:
\`\`\`
git diff --cached
\`\`\`
Please generate a concise, one-line commit message for these changes, conforming to the Conventional Commits specification."
return $message
}
# Function to read user input
function Read-Input {
param (
[string]$Prompt
)
Write-Host -NoNewline $Prompt
return Read-Host
}
# Main script
Write-Host "Generating..."
$commitMessage = Generate-CommitMessage
while ($true) {
Write-Host "`nProposed commit message:"
Write-Host $commitMessage
$choice = Read-Input "Do you want to (a)ccept, (e)dit, (r)egenerate, or (c)ancel? "
switch ($choice.ToLower()) {
'a' {
if ($commitMessage) {
git commit -m "$commitMessage"
if ($?) {
Write-Host "Changes committed successfully!"
return 0
} else {
Write-Host "Commit failed. Please check your changes and try again."
return 1
}
} else {
Write-Host "Commit message cannot be empty. Please try again."
}
}
'e' {
$commitMessage = Read-Input "Enter your commit message: "
if ($commitMessage) {
git commit -m "$commitMessage"
if ($?) {
Write-Host "Changes committed successfully with your message!"
return 0
} else {
Write-Host "Commit failed. Please check your message and try again."
return 1
}
} else {
Write-Host "Commit message cannot be empty. Please try again."
}
}
'r' {
Write-Host "Regenerating commit message..."
$commitMessage = Generate-CommitMessage
}
'c' {
Write-Host "Commit cancelled."
return 1
}
default {
Write-Host "Invalid choice. Please try again."
}
}
}
}
除此之外，你还可以使用其它网络上的大语言模型 api 端点，比如使用 github model 的 gpt-4o-mini
function Invoke-ChatCompletion {
param (
[string]$GitHubToken = "你的 GitHub 令牌填写在此处",
[string]$UserMessage,
[string]$SystemMessage = "You are a helpful assistant."
)
# 设置请求头
$headers = @{
"Content-Type" = "application/json"
"Authorization" = "Bearer $GitHubToken"
}
# 创建请求体
$body = @{
"messages" = @(
@{
"role" = "system"
"content" = $SystemMessage
},
@{
"role" = "user"
"content" = $UserMessage
}
)
"temperature" = 1.0
"top_p" = 1.0
"max_tokens" = 1000
"model" = "gpt-4o-mini"
}
# 将请求体转换为 JSON 格式
$bodyJson = $body | ConvertTo-Json
try {
# 发送 POST 请求
$response = Invoke-RestMethod -Uri "https://models.inference.ai.azure.com/chat/completions" -Method Post -Headers $headers -Body $bodyJson
# 输出响应中的 content 内容
$content = $response.choices[0].message.content
Write-Output $content
} catch {
# 输出错误信息
Write-Error $_.Exception.Message
}
}
function Generate-CommitMessage {
$diff = git diff --cached
$userMessage = @"
Below is a diff of all staged changes, coming from the command:
\`\`\`
git diff --cached
\`\`\`
Please generate a concise, one-line commit message for these changes, conforming to the Conventional Commits specification.
$diff
"@
# 调用 Invoke-ChatCompletion 函数生成提交信息
$commitMessage = Invoke-ChatCompletion -GitHubToken "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" -UserMessage $userMessage
return $commitMessage
}
function Read-Input {
param (
[string]$Prompt
)
Write-Host -NoNewline $Prompt
return Read-Host
}
function gco {
Write-Host "Generating..."
$commitMessage = Generate-CommitMessage
while ($true) {
Write-Host "`nProposed commit message:"
Write-Host $commitMessage
$choice = Read-Input "Do you want to (a)ccept, (e)dit, (r)egenerate, or (c)ancel? "
switch ($choice.ToLower()) {
'a' {
if ($commitMessage) {
git commit -m "$commitMessage"
if ($?) {
Write-Host "Changes committed successfully!"
return 0
} else {
Write-Host "Commit failed. Please check your changes and try again."
return 1
}
} else {
Write-Host "Commit message cannot be empty. Please try again."
}
}
'e' {
$commitMessage = Read-Input "Enter your commit message: "
if ($commitMessage) {
git commit -m "$commitMessage"
if ($?) {
Write-Host "Changes committed successfully with your message!"
return 0
} else {
Write-Host "Commit failed. Please check your message and try again."
return 1
}
} else {
Write-Host "Commit message cannot be empty. Please try again."
}
}
'r' {
Write-Host "Regenerating commit message..."
$commitMessage = Generate-CommitMessage
}
'c' {
Write-Host "Commit cancelled."
return 1
}
default {
Write-Host "Invalid choice. Please try again."
}
}
}
}
2. 执行，生成 git commit message
在 PowerShell 执行. $PROFILE 重新加载配置文件，在项目目录执行 gco
