在编辑特定类型的文件时，我经常使用数字，而且这大多是乏味的工作。该文件的格式如下：

damagebase = 8.834
    "abc_foo.odf" 3.77
    "def_bar.odf" 3.77
    "ghi_baz.odf" 3.77
    "jkl_blah.odf" 4.05
    ...

对于编写一个解析这个并让我以编程方式更改每个数字的脚本，你会推荐什么？

语言：我使用 C#、一些 F#（菜鸟）和 Lua。如果您建议正则表达式，您能否提供具体的，因为我不熟悉它们？

Perl 非常适合这样的东西。这是一个 perl 脚本，可以做你想做的事。

#!/usr/bin/env perl

$multiplier = 2.0;

while (<>)
{
    $n = /=/ ? 2 : 1;
    @tokens = split;
    $tokens[$n] *= $multiplier;

    print "\t" if not /=/;
    print join(' ', @tokens) . "\n";
}

用法：

./file.pl input_file > output_file

如果这真的是您想要做的，请使用 awk：

awk '{$NF *= 2.5 ; print }' < input_file > output_file

编辑：好的，如果你想保留你描述的空格，这应该可以工作（尽管它变得不优雅）。

awk '{$NF *= 2.5} /^\"/{print "\t" $0} !/^\"/{print}' < input_file > output_file

您可以像这样使用 AWK（请注意如何轻松转换格式），

sed 's/damagebase =/damagebase=/g' input.txt |\
    awk '{printf "     %s %s\n",$1,3.1*$2}' |\
    sed 's/.*damagebase=/damagebase =/g'

3.1我在这个示例脚本中将第二列乘以。
请注意，要恢复您的格式，
在 printf 的开头插入了一个 TAB，
这两个sed命令将您的格式来回转换为适合 AWK 命令的格式

您可以匹配非空白的运行并平底船到Double.Parse：

int multiplier = 3;

string input =
  "damagebase = 8.834\n" +
  "  \"abc.odf\" 3.77\n" +
  "  \"def.odf\" 3.77\n" +
  "  \"ghi.odf\" .77\n" +
  "  \"jkl.odf\" -4.05\n" +
  "  \"mno.odf\" 5\n";

Regex r = new Regex(@"^(\w+)\s*=\s*(\S+)" +
                    @"(?:\s+""([^""]+)""\s+(\S+))+",
                    RegexOptions.Compiled | RegexOptions.Multiline);

Match m = r.Match(input);
if (m.Success) {
  double header = Double.Parse(m.Groups[2].Value);
  Console.WriteLine("{0} = {1}", m.Groups[1].Value,
                                 header * multiplier);

  CaptureCollection files = m.Groups[3].Captures;
  CaptureCollection nums  = m.Groups[4].Captures;
  for (int i = 0; i < files.Count; i++) {
    double val = Double.Parse(nums[i].Value);
    Console.WriteLine(@"  ""{0}"" {1}", files[i].Value,
                                        val * multiplier);
  }
}
else
  Console.WriteLine("no match");

运行它给出

damagebase = 26.502
  "abc.odf" 11.31
  "def.odf" 11.31
  "ghi.odf" 2.31
  "jkl.odf" -12.15
  "mno.odf" 15

我试过了

static void Main(string[] args)
{
    Console.WriteLine("Please enter the multiplier:");
    string stringMult = Console.ReadLine();
    int multiplier;
    Int32.TryParse(stringMult, out multiplier);
    StreamReader sr = new StreamReader(@"C:\Users\[obscured]\Desktop\Fleetops Mod\Data To Process.txt", true);
    string input = sr.ReadToEnd();
    sr.Close();
    StreamWriter sw = new StreamWriter(@"C:\Users\[obscured]\Desktop\Fleetops Mod\Data To Process.txt", false);
    Regex r = new Regex(@"^(\w+)\s*=\s*(\S+)" +
            @"(?:\s+""([^""]+)""\s+(\S+))+",
            RegexOptions.Compiled | RegexOptions.MultiLine);
    Match m = r.Match(input);
    if (m.Success) {
        double header = Double.Parse(m.Groups[2].Value);
        sw.WriteLine("{0} = {1}", m.Groups[1].Value,
                         header * multiplier);
        CaptureCollection files = m.Groups[3].Captures;
        CaptureCollection nums  = m.Groups[4].Captures;
        for (int i = 0; i < files.Count; i++) {
            double val = Double.Parse(nums[i].Value);
            sw.WriteLine(@"  ""{0}"" {1}", files[i].Value,
                                val * multiplier);
        }
    }
    else
        Console.WriteLine("no match");
    sw.Close();
    Console.WriteLine("Done!");
    Console.ReadKey();
}

（感谢 gbacon）即使我输入正确的数据，它也会返回“不匹配”。为什么这样做？这是测试数据：

我的理论是，因为每个非标题行之前的空格是一个制表符（它不会在这里显示），所以正则表达式不匹配。如果您想知道，空格很重要。
