.bat 脚本删除尾随空格

Question

我对通过 Windows 编写脚本相当陌生。也许我什至需要脚本以外的东西。我在 linux 中使用 sed 和 csv 文件做了一些类似的事情，但我想制作一个 .bat 脚本文件（或类似的东西），它会接收一个 c 头文件并删除所有尾随空格。

编辑原因：（我的 Svn 存储库不允许尾随空格，并且在使用 C++ UI 表单时，每次添加新对象时都会添加带有尾随空格的 cmets，例如按钮）

编辑： 它发生在如下所示的 cmets 之后

        "// 
         // outputStringsTab
         // "

示例代码段：

#pragma region Windows Form Designer generated code
      /// <summary>
      /// Required method for Designer support - do not modify
      /// the contents of this method with the code editor.
      /// </summary>

Windows 批处理脚本不提供图灵完备的编程语言，主要用于顾名思义 - 将多个命令批处理在一起（否则您会从命令行执行）。现代 Windows 确实提供了大量对 MS-DOS 批处理文件的扩展，但它仍然不是满足您要求的合适工具。

Windows 现在包含PowerShell 作为基本命令行处理器和批处理文件的替代品；使用它可能会更好，但是如果您可能正在使用 C 和 C++，那么使用您已经熟悉的语言编写自己的实用程序就足够简单了？

Answer 2

修剪空间

filter ts {l|r|lr|lc count}

修剪一行中的前导和尾随空格。

l - 删除前导空格。

r - 删除尾随空格。

lr - 删除前导和尾随空格。

lc - 删除 <count> 前导空格。

示例

修复win.ini，不需要修复，发送到屏幕

filter trimspace lc 5 <"%systemroot%\win.ini"

vbs 脚本

Set Arg = WScript.Arguments
set WshShell = createObject("Wscript.Shell")
Set Inp = WScript.Stdin
Set Outp = Wscript.Stdout

If LCase(Arg(1)) = "l" then 
    Do Until Inp.AtEndOfStream
        Line=Inp.readline
        outp.writeline LTrim(Line)
    Loop
ElseIf LCase(Arg(1)) = "r" then
    Do Until Inp.AtEndOfStream
        Line=Inp.readline
        outp.writeline RTrim(Line)
    Loop
ElseIf LCase(Arg(1)) = "lr" then
    Do Until Inp.AtEndOfStream
        Line=Inp.readline
        outp.writeline Trim(Line)
    Loop
ElseIf LCase(Arg(1)) = "lc" then
    Count = Cint(LCase(Arg(2)))
    Do Until Inp.AtEndOfStream
        Line=Inp.readline
        If Left(Line,Count) = Space(Count) then
            outp.writeline Mid(Line, Count +1)
        Else
            outp.writeline LTrim(Line)
        End If
    Loop
End If

使用批处理文件来启动它

  cscript //nologo <pathtovbsscript\vbsscript.vbs> lc 5 <file.h

一般用途

过滤器用于命令提示符。 Filter.vbs 必须与 cscript.exe 一起运行。如果您只是输入 filter，它将运行一个批处理文件，该文件会自动执行此操作。

 filter subcommand [parameters]

过滤器仅读取和写入标准输入和标准输出。这些仅在命令提示符下可用。

filter <inputfile >outputfile
filter <inputfile | other_command
other_command | filter >outputfile
other_command | filter | other_command
