如何在GUI界面中最佳地显示rsync进度？

Question

我使用 rsync以一种与服务器无关的方式同步文件到Windows客户端。有哪些方法可用于将rsync的进度发送给父进程，以在GUI进度条中显示？我想有两三个选择。(1) 观察STDOUT (2) 观察rsync.exe日志文件，类似于unix的tail (3) 在内存中观察rsync控制台输出。哪一个是最好/首选的？

对于这种类型的任务，我使用自己的AutoIt脚本（免费软件，仅适用于Windows）。该脚本将标准输出重定向到一个图形窗口中，并显示它，具有滚动回退等功能（在像XCOPYs / PKZIPs这样的长时间处理中非常有用，以检查是否发生任何错误）。

我使用AutoIt是因为它是免费的，非常易于使用，并且可以快速编译成.EXE文件。我认为它是这种类型任务的完美替代品，而不必使用完整的编程语言。缺点是它仅适用于Windows系统。

$sCmd = "DIR E:\*.AU3 /S"  ; Test command
$nAutoTimeout = 10      ; Time in seconds to close window after finish

$nDeskPct = 60          ; % of desktop size (if percent)

; $nHeight = 480          ; height/width of the main window (if fixed)
; $nWidth = 480

$sTitRun = "Executing process. Wait...."     ; 
$sTitDone = "Process done"                ; 

$sSound = @WindowsDir & "\Media\Ding.wav"       ; End Sound

$sButRun = "Cancel"                           ; Caption of "Exec" button
$sButDone = "Close"                            ; Caption of "Close" button

#include <GUIConstants.au3>
#include <Constants.au3>
#Include <GuiList.au3>

Opt("GUIOnEventMode", 1)

if $nDeskPct > 0 Then
    $nHeight = @DesktopHeight * ($nDeskPct / 100)
    $nWidth = @DesktopWidth * ($nDeskPct / 100)
EndIf


If $CmdLine[0] > 0 Then
    $sCmd = ""
    For $nCmd = 1 To $CmdLine[0]
        $sCmd = $sCmd & " " & $CmdLine[$nCmd]
    Next

    ; MsgBox (1,"",$sCmd)
EndIf

; AutoItSetOption("GUIDataSeparatorChar", Chr(13)+Chr(10))

$nForm = GUICreate($sTitRun, $nWidth, $nHeight)
GUISetOnEvent($GUI_EVENT_CLOSE, "CloseForm")

$nList = GUICtrlCreateList ("", 10, 10, $nWidth - 20, $nHeight - 50, $WS_BORDER + $WS_VSCROLL)
GUICtrlSetFont (-1, 9, 0, 0, "Courier New")

$nClose = GUICtrlCreateButton ($sButRun, $nWidth - 100, $nHeight - 40, 80, 30)
GUICtrlSetOnEvent (-1, "CloseForm")

GUISetState(@SW_SHOW)   ;, $nForm)

$nPID = Run(@ComSpec & " /C " & $sCmd, ".", @SW_HIDE, $STDOUT_CHILD)
; $nPID = Run(@ComSpec & " /C _RunErrl.bat " & $sCmd, ".", @SW_HIDE, $STDOUT_CHILD)     ; # Con ésto devuelve el errorlevel en _ERRL.TMP

    $sLine = StdoutRead($nPID)
    If @error Then ExitLoop

    If StringLen ($sLine) > 0 then
        $sLine = StringReplace ($sLine, Chr(13), "|")
        $sLine = StringReplace ($sLine, Chr(10), "")
        if StringLeft($sLine, 1)="|" Then
            $sLine = " " & $sLine
        endif

        GUICtrlSetData ($nList, $sLine)

        _GUICtrlListSelectIndex ($nList, _GUICtrlListCount ($nList) - 1)
    EndIf
Wend

$sLine = " ||"
GUICtrlSetData ($nList, $sLine)
_GUICtrlListSelectIndex ($nList, _GUICtrlListCount ($nList) - 1)

GUICtrlSetData ($nClose, $sButDone)

WinSetTitle ($sTitRun, "", $sTitDone)
If $sSound <> "" Then
    SoundPlay ($sSound)
EndIf

$rInfo = DllStructCreate("uint;dword")      ; # LASTINPUTINFO
DllStructSetData($rInfo, 1, DllStructGetSize($rInfo));

DllCall("user32.dll", "int", "GetLastInputInfo", "ptr", DllStructGetPtr($rInfo))
$nLastInput = DllStructGetData($rInfo, 2)

$nTime = TimerInit()

While 1
    If $nAutoTimeout > 0 Then
        DllCall("user32.dll", "int", "GetLastInputInfo", "ptr", DllStructGetPtr($rInfo))
        If DllStructGetData($rInfo, 2) <> $nLastInput Then
            ; Tocó una tecla
            $nAutoTimeout = 0
        EndIf
    EndIf

    If $nAutoTimeout > 0 And TimerDiff ($nTime) > $nAutoTimeOut * 1000 Then
        ExitLoop

.NET有一种非常直接的方法来读取和观察STDOUT。
我想这可能是最干净的方式，因为它不依赖于任何外部文件，只需要rsync的路径。如果没有包装库，也不会太惊讶。如果没有，就编写并开源它吧 :)

我已经为此构建了自己的简单对象，我可以在其中获得很多重复使用，我可以用 cmdline、web page、webservice 包装它，将输出写入文件等等。

注释项包含一些 rsync 示例--

有时我想做的是将 rsync（和 cygwin）嵌入资源中，并将其制作成单个 .net 可执行文件--
