在Inno Setup中使用Define和Constant

问题描述

我对Inno Setup中的#define有疑问.我已经进行了设置，确定谁可以很好地工作，并且如果我需要做一些修改，我正在考虑应用程序的未来.例如，如果我更改版本(主要版本，次要版本，内部版本，补丁程序...)，则我不想每次都更改所有行(如注册表).

I've a question about the #define in Inno Setup. I've make a setup who's working well and i'm thinking of the future of app if i have some modification to do. For example, if i change the version (Major, Minor, Build, Patch,...) i doesn't want to change all the line (like Registry) at each time.

所以我尝试做这样的事情:

So i try to make something like that :

#define MyAppMajor "5"
#define MyAppMinor "5"
#define MyAppBuild "1"
#define MyAppPatch "1"

...

[Files]
Source: "D:\ProgramFiles\..."; DestDir: "{app}\Program\{MyAppMajor}.{MyAppMinor}\"; Flags: ignoreversion;

[Registry]
Root: "HKLM32"; Subkey: "Software\program\"; ... ; ValueData: "{MyAppMajor}.{MyAppMinor}.{MyAppBuild}.{MyAppPatch}";

但是无法编译，它说:

"未知常量"MyAppMajor".如果要嵌入单个"{"而不是常量，请使用两个连续的"{"字符"..

是否可以执行类似的操作来进行版本控制或其他常量?

Is there a way to do something like that for versionning or another constant ?

推荐答案

您错过了使用#字符(或 #emit ，是该版本的较长版本)，用于将已定义的变量内联到脚本中，例如:

You missed to use the # char (or #emit, which is the longer version of the same), that is used to inline a defined variable into the script, e.g.:

#define MyAppMajor "5"
#define MyAppMinor "5"
#define MyAppBuild "1"
#define MyAppPatch "1"

[Files]
...; DestDir: "{app}\Program\{#MyAppMajor}.{#MyAppMinor}\"; Flags: ignoreversion;

[Registry]
...; ValueData: "{#MyAppMajor}.{#MyAppMinor}.{#MyAppBuild}.{#MyAppPatch}";

如果缺少此常量，则编译器会期望(内置)名为MyAppMajor，MyAppMinor等的常量，而这些常量不存在；这些常量不存在.因此是错误.

When missing this, the compiler expected (built-in) constants called MyAppMajor, MyAppMinor etc., whose doesn't exist; hence the error.

但是，您要复制的内容可能是Inno Setup中内置的，其 AppVersion 指令.这可能是有用的，例如结合从包含的文件版本信息中读取应用程序二进制文件的版本:

But, what you're trying to replicate is probably built-in in Inno Setup as the AppVersion directive. It might be useful e.g. in conjunction of reading the version of the application binary from its included file version information:

#define AppVersion GetFileVersion('C:\MyApp.exe')

[Setup]
...
AppVersion={#AppVersion}
