如何用AppleScript获取终端脚本输出并显示在Scrollable Text View中？

完全可以实现这个需求。纯AppleScript本身没有原生UI控件，需要借助AppleScriptObjC调用Cocoa框架创建包含Scrollable Text View的窗口，同时捕获Shell命令的输出并展示。下面分两种场景给出实现方案：

场景1：命令执行完毕后一次性展示全部输出 #

适合不需要实时查看进度的命令，用do shell script同步捕获输出：

use framework "Cocoa"
use scripting additions

-- 创建基础窗口
set mainWindow to current application's NSWindow's alloc()'s initWithContentRect:{{100, 100}, {600, 400}} ¬
    styleMask:(current application's NSTitledWindowMask + current application's NSClosableWindowMask + current application's NSMiniaturizableWindowMask) ¬
    backing:(current application's NSBackingStoreBuffered) defer:true
mainWindow's setTitle:"Shell Output Viewer"

-- 创建滚动文本视图
set scrollView to current application's NSScrollView's alloc()'s initWithFrame:(mainWindow's contentView()'s bounds())
scrollView's setHasVerticalScroller:true
scrollView's setHasHorizontalScroller:true
scrollView's setAutoresizingMask:(current application's NSViewWidthSizable + current application's NSViewHeightSizable)

set outputTextView to current application's NSTextView's alloc()'s initWithFrame:(scrollView's bounds())
outputTextView's setEditable:false
outputTextView's setAutoresizingMask:(current application's NSViewWidthSizable + current application's NSViewHeightSizable)
scrollView's setDocumentView:outputTextView

mainWindow's contentView()'s addSubview:scrollView

-- 执行Shell命令并捕获输出（包含错误信息）
try
    set commandOutput to do shell script "git clone https://github.com/torvalds/linux.git"
on error errMsg number errCode
    set commandOutput to "执行错误 (" & errCode & "): " & errMsg
end try

-- 将输出写入文本视图
outputTextView's setString:commandOutput

-- 显示窗口并启动应用循环
mainWindow's makeKeyAndOrderFront:me
current application's NSApp's run()

场景2：实时展示命令输出（如git clone的进度） #

如果需要实时查看命令的持续输出（比如克隆仓库的进度条），do shell script的同步模式会阻塞UI，此时需要用NSTask异步执行命令并实时捕获输出：

use framework "Cocoa"
use scripting additions

property outputTextView : missing value

-- 创建基础窗口
set mainWindow to current application's NSWindow's alloc()'s initWithContentRect:{{100, 100}, {600, 400}} ¬
    styleMask:(current application's NSTitledWindowMask + current application's NSClosableWindowMask + current application's NSMiniaturizableWindowMask) ¬
    backing:(current application's NSBackingStoreBuffered) defer:true
mainWindow's setTitle:"Real-time Shell Output Viewer"

-- 创建滚动文本视图
set scrollView to current application's NSScrollView's alloc()'s initWithFrame:(mainWindow's contentView()'s bounds())
scrollView's setHasVerticalScroller:true
scrollView's setHasHorizontalScroller:true
scrollView's setAutoresizingMask:(current application's NSViewWidthSizable + current application's NSViewHeightSizable)

set outputTextView to current application's NSTextView's alloc()'s initWithFrame:(scrollView's bounds())
outputTextView's setEditable:false
outputTextView's setAutoresizingMask:(current application's NSViewWidthSizable + current application's NSViewHeightSizable)
scrollView's setDocumentView:outputTextView

mainWindow's contentView()'s addSubview:scrollView

-- 配置异步任务执行git命令
set gitTask to current application's NSTask's new()
gitTask's setLaunchPath:"/usr/bin/git"
gitTask's setArguments:{"clone", "https://github.com/torvalds/linux.git"}

-- 创建管道捕获标准输出和错误输出
set outputPipe to current application's NSPipe's pipe()
gitTask's setStandardOutput:outputPipe
gitTask's setStandardError:outputPipe -- 将错误输出合并到同一管道

set fileHandle to outputPipe's fileHandleForReading()
-- 设置可读回调，实时读取输出并更新UI
fileHandle's readabilityHandler:^(current application's NSFileHandle *handle) {
    set data to handle's availableData()
    if data's |length|() > 0 then
        set newOutput to current application's NSString's alloc()'s initWithData:data encoding:(current application's NSUTF8StringEncoding)
        -- 必须在主线程更新UI，避免线程冲突
        current application's dispatch_sync(current application's dispatch_get_main_queue(), ^{
            outputTextView's insertText:newOutput
            -- 自动滚动到最新内容
            set endRange to current application's NSMakeRange(outputTextView's string()'s |length|(), 0)
            outputTextView's scrollRangeToVisible:endRange
        })
    else
        handle's setReadabilityHandler:(missing value) -- 无数据时停止监听
    end if
}

-- 启动任务
gitTask's launch()

-- 显示窗口并启动应用循环
mainWindow's makeKeyAndOrderFront:me
current application's NSApp's run()

使用说明 #

1. 打开Script Editor，将代码粘贴进去，格式选择AppleScript + Objective-C
2. 运行脚本，会弹出对应的窗口，执行命令后输出会显示在滚动文本视图中
