I have an Inno Setup script with preprocessor directives (#define
s, #if
s, etc.)
I want to run the Inno Setup preprocessor on my script and see the preprocessor's output (translation in Inno-Setup-speak). That is, I want to look at the result of the preprocessor which it normally feeds into the Inno Setup Compiler, where all the references to {#something}
are changed into whatever something
was defined as.
I look at the command line options (of iscc.exe
) and #pragma
directives and did not find what I'm looking for. I see that I can specify not to run the compiler (#pragma -c- | /$c-
) but I did not find a way to look at the output of the preprocessor.
In short, how do I look at the output of the Inno Setup preprocessor?
When all else fails look for the answer yourself
Add the following line right at the end of the script.
This will generate a file preprocessed.iss
with all macros expanded and #define
s, #if
s etc. processed.
#expr SaveToFile(AddBackslash(SourcePath) + "Preprocessed.iss")
