Inno Setup：为文件夹及其子文件夹中的所有文件动态添加组件

假设文件在编译时可用，则可以使用Inno Setup Preprocessor递归宏来生成[Files]和[Components]部分。

此代码部分基于以编程方式生成Inno Setup文件标志。

#pragma parseroption -p-

#define FileEntry(Source, Dest) \
    Local[0] = Copy(Dest, 2, Len(Dest) - 1), \
    Local[1] = StringChange(Local[0], ".", ""), \
    "[Files]\n" + \
    "Source: " + Source + "; DestDir: {app}" + ExtractFileDir(Dest) + \
        "; Components: " + Local[1] + "\n" + \
    "[Components]\n" + \
    "Name: " + Local[1] + "; Description: " + ExtractFileName(Dest) + "\n"

#define DirEntry(Source, Dest) \
    Local[0] = Copy(Dest, 2, Len(Dest) - 1), \
    Local[1] = StringChange(Local[0], ".", ""), \
    "[Components]\n" + \
    "Name: " + Local[1] + "; Description: " + ExtractFileName(Dest) + "\n"

#define ProcessFile(Source, Dest, FindResult, FindHandle) \
    FindResult \
        ? \
            Local[0] = FindGetFileName(FindHandle), \
            Local[1] = Source + "\\" + Local[0], \
            Local[2] = Dest + "\\" + Local[0], \
            (Local[0] != "." && Local[0] != ".." \
                ? (DirExists(Local[1]) \
                     ? DirEntry(Local[1], Local[2]) + ProcessFolder(Local[1], Local[2]) \
                     : FileEntry(Local[1], Local[2])) \
                : "") + \
            ProcessFile(Source, Dest, FindNext(FindHandle), FindHandle) \
        : \
            ""

#define ProcessFolder(Source, Dest) \
    Local[0] = FindFirst(Source + "\\*", faAnyFile), \
    ProcessFile(Source, Dest, Local[0], Local[0])

#pragma parseroption -p+

#emit ProcessFolder("D:\SomeDirectory", "")

如果D:\SomeDirectory包含以下文件：

file1.txt
file2.txt
sub1\file11.txt
sub1\file12.txt
sub2\file21.txt
sub2\file22.txt

上面的代码将生成：

[Files]
Source: D:\SomeDirectory\file1.txt; DestDir: {app}; Components: file1txt
[Components]
Name: file1txt; Description: file1.txt
[Files]
Source: D:\SomeDirectory\file2.txt; DestDir: {app}; Components: file2txt
[Components]
Name: file2txt; Description: file2.txt
[Components]
Name: sub1; Description: sub1
[Files]
Source: D:\SomeDirectory\sub1\file11.txt; DestDir: {app}\sub1; Components: sub1\file11txt
[Components]
Name: sub1\file11txt; Description: file11.txt
[Files]
Source: D:\SomeDirectory\sub1\file12.txt; DestDir: {app}\sub1; Components: sub1\file12txt
[Components]
Name: sub1\file12txt; Description: file12.txt
[Components]
Name: sub2; Description: sub2
[Files]
Source: D:\SomeDirectory\sub2\file21.txt; DestDir: {app}\sub2; Components: sub2\file21txt
[Components]
Name: sub2\file21txt; Description: file21.txt
[Files]
Source: D:\SomeDirectory\sub2\file22.txt; DestDir: {app}\sub2; Components: sub2\file22txt
[Components]
Name: sub2\file22txt; Description: file22.txt

在安装程序中，您将获得：

但是请注意，可以通过这种方式处理的文件数受预处理程序堆栈的限制。

如果遇到这种情况，另一种（尽管很丑陋和复杂）的方法是使用用户定义的过程。有关使用此处显示的方法和用户定义的过程来实现递归文件处理的示例，请参见Inno Setup-递归子目录，而无需创建这些子目录。
