Inno Setup中的通配符(测试固定字符串前缀后是否有任何值) [英] Wildcard characters in Inno Setup (test if there is any value after fixed string prefix)

问题描述

Inno Setup是否有一些通配符?我正在尝试遍历字符串，如果要搜索某个值，程序应返回1(我正在使用Pos()函数，该函数已经完成了我需要的操作)，但是我的问题是该部分我要搜索的字符串不是静态的，因此我需要一些通配符，例如*，可以替换一个或多个字符.

Is there some wildcard characters for Inno Setup? I am trying to go through string and if there is some value that I'm searching for, the program should return 1 (I'm using Pos() function that already does what I need), but my problem here is that the part of string that I'm searching for is not static, so I need some wildcard character like * that can replace one or more characters.

推荐答案

Inno Setup Pascal脚本中没有模式匹配功能.

There's no pattern matching functionality in Inno Setup Pascal Script.

但是您可以使用如下函数:

But you can use a function like this:

function AnythingAfterPrefix(S: string; Prefix: string): Boolean;
begin
  Result := 
     (Copy(S, 1, Length(Prefix)) = Prefix) and
     (Length(S) > Length(Prefix));
end;

并像这样使用它:

if AnythingAfterPrefix(S, 'Listing connections...') then

您可能想添加 TrimRight 来忽略尾随空格:

You may want to add TrimRight to ignore trailing spaces:

if AnythingAfterPrefix(TrimRight(S), 'Listing connections...') then
