如何在Inno Setup中为OutputBaseFilename的版本组件填充零 [英] How to pad version components with zeroes for OutputBaseFilename in Inno Setup
问题描述
我有Inno Setup 6.1.2安装脚本,其中的 main.sub.batch
版本是这样形成的:
I have Inno Setup 6.1.2 setup script where the version main.sub.batch
is formed like this:
#define AppVerText() \
GetVersionComponents('..\app\bin\Release\app.exe', \
Local[0], Local[1], Local[2], Local[3]), \
Str(Local[0]) + "." + Str(Local[1]) + "." + Str(Local[2])
稍后在安装程序部分中,我将其用作安装程序包的名称:
Later in the setup part, I use it for the name of setup package:
[Setup]
OutputBaseFilename=app.{#AppVerText}.x64
生成的文件名将为 app.1.0.2.x64.exe
,这很好.为了使其完美,我想以带有零填充组件的形式 app.1.00.002.x64.exe
结尾.
The resulting filename will be app.1.0.2.x64.exe
, which is mighty fine. To make it perfect, I'd like to end up with form app.1.00.002.x64.exe
with zero-padded components.
我在文档中没有找到 PadLeft
之类的东西.不幸的是,我也无法理解如何在这种情况下使用我自己的Pascal函数.我可以在 Code
部分为此定义一个函数吗?
I did not find anything like PadLeft
in documentation. Unfortunately I also fail to understand how to use my own Pascal function in this context. Can I define a function in Code
section for this?
推荐答案
一种快速而肮脏的解决方案,用于将数字填充到 Inno Setup预处理器:
A quick and dirty solution to pad the numbers in the Inno Setup preprocessor:
#define AppVerText() \
GetVersionComponents('..\app\bin\Release\app.exe', \
Local[0], Local[1], Local[2], Local[3]), \
Str(Local[0]) + "." + \
(Local[1] < 10 ? "0" : "") + Str(Local[1]) + "." + \
(Local[2] < 100 ? "0" : "") + (Local[2] < 10 ? "0" : "") + Str(Local[2])
如果您想为填充使用通用函数,请使用以下命令:
If you want a generic function for the padding, use this:
#define PadStr(S, C, L) Len(S) < L ? C + PadStr(S, C, L - 1) : S
使用方式如下:
#define AppVerText() \
GetVersionComponents('MyProg.exe', \
Local[0], Local[1], Local[2], Local[3]), \
Str(Local[0]) + "." + PadStr(Str(Local[1]), "0", 2) + "." + \
PadStr(Str(Local[1]), "0", 3)
Pascal脚本 Code
(例如这一个)在这里无济于事,因为它在安装时运行,而您在编译时需要它.因此,预处理器是唯一的方法.
Pascal Script Code
(like this one) won't help here, as it runs on the install-time, while you need this on the compile-time. So the preprocessor is the only way.
