PyQt ui2py 使用PowerShell将ui文件转为py文件并且将导入模块PyQt或PySide转换为qtpy模块开箱即用

前言

由于需要使用不同的qt环境（PySide，PyQt）所以写了这个脚本，使用找到的随便一个uic命令去转换ui文件，然后将导入模块换成qtpy这个通用库(支持pyside2-6，pyqt5-6)，老版本的是Qt.py(支持pyside0-2~pyqt4-5)你可以自己改

使用

将内容保存为 ui2py.ps1 放置到后缀 ui 文件的同目录下
在拥有环境的powershell中运行 .\ui2py

<#
.SYNOPSIS
Convert all ui files in the same directory to py files for Python to use

.DESCRIPTION
It needs to be used on terminals that have a Python environment, making sure that pyuic* or pyside*-uic is present
This script replaces the import 'from PyQt*' or 'from PySide*' in the py file with the 'from qtpy' module after compilation

.EXAMPLE
PS> .\MyScript.ps1
Run directly, no parameters required

# Check whether the uic command exists
$_commands = @("pyuic5", "pyside2-uic", "pyuic6", "pyside6-uic", "pyside-uic", "pyuic")
$command = $null
foreach ($cmd in $_commands)
{
    $command = Get-Command $cmd -ErrorAction SilentlyContinue
    if ($command)
    {
        break
    }
}
if (-not$command)
{
    Write-Host "Command not found."
    exit 1
}
$command = $command.Name
Write-Output "Use command: $command"

# Gets the folder where the current script is located
$scriptDirectory = Split-Path -Parent $MyInvocation.MyCommand.Definition

# Perform conversion operations for all *.ui files in the folder
Get-ChildItem -Path $scriptDirectory -Filter *.ui | ForEach-Object {
    $uiFile = $_.FullName
    $pyFile = $_.BaseName + ".py"
    $pyFilePath = Join-Path $scriptDirectory $pyFile

    Write-Host $uiFile
    Write-Host $pyFilePath

    # Convert '.ui' to '.py'
    & $command -o $pyFilePath $uiFile

    # Check whether the file is successfully converted
    if (Test-Path $pyFilePath)
    {
        # Replace import module
        (Get-Content $pyFilePath -Encoding UTF8) -replace "from (PyQt[456]?|PySide[26]?)", "from qtpy" | Set-Content $pyFilePath -Encoding UTF8
        Write-Host "Files have been converted and modified successfully: $pyFile"
    }
    else
    {
        Write-Host "convert failed: $uiFile"
    }
}

如果你的项目是有结构的比如下图
目录结构
需要将ui转出的py文件放置到上层的ui目录中的话，可以修改以下内容
添加父文件夹$parentDirectory = Split-Path -Parent $scriptDirectory


# Gets the folder where the current script is located
$scriptDirectory = Split-Path -Parent $MyInvocation.MyCommand.Definition
$parentDirectory = Split-Path -Parent $scriptDirectory

# Perform conversion operations for all *.ui files in the folder
Get-ChildItem -Path $scriptDirectory -Filter *.ui | ForEach-Object {
    $uiFile = $_.FullName
    $pyFile = $_.BaseName + ".py"
    $pyFilePath = Join-Path $parentDirectory ("ui/" + $pyFile)
