I want to update AppVersion value in [Setup] section at compile time from config.xml file by parsing Version tag.
Config.xml file has below configuration:
<?xml version="1.0" encoding="utf-8"?>
<Configuration>
<Version>1.0.1</Version>
</Configuration>
My application is using config.xml file for application version. I also want to use the same version in Inno Setup installer version.
I am new in Inno Setup script development. It would be very helpful if someone provide me right approach.
You can use a simple PowerShell code like:
$version = ([xml](Get-Content 'config.xml')).Configuration.Version
Set-Content -Path 'version.txt' -Value $version
And run it using Inno Setup preprocessor:
#define RetrieveVersion(str FileName) \
Local[0] = AddBackslash(GetEnv("TEMP")) + "version.txt", \
Local[1] = \
"-ExecutionPolicy Bypass -Command """ + \
"$version = ([xml](Get-Content '" + FileName + "')).Configuration.Version;" + \
"Set-Content -Path '" + Local[0] + "' -Value $version;" + \
"""", \
Exec("powershell.exe", Local[1], SourcePath, , SW_HIDE), \
Local[2] = FileOpen(Local[0]), \
Local[3] = FileRead(Local[2]), \
FileClose(Local[2]), \
DeleteFileNow(Local[0]), \
Local[3]
[Setup]
AppVersion={#RetrieveVersion("C:\path\config.xml")}
For a similar question, see Read application version from a text file in Inno Setup.
Though I assume that the application compiler actually uses the config.xml for the application executable version. If that's the case, you can retrieve the version from the .exe more easily.
