[SOLVED] Find a directory using wildcard in Inno Setup

Find a directory using wildcard in Inno Setup

I'm trying to get all the files in a directory recursively while using wildcard within the name of the directory in Inno Setup script.

I have came across examples for filename but none for a directory search.

Use Case: Basically, we have moved to using NuGet packages for our internal development projects. So each project makes a NuGet package which can be consumed by other project and/or developer.

Part of this we wish to use the Inno Setup to use the dlls and/or files from a NuGet package.

For example, we need to find the package folder matching "../packages/PackagesA.../", e.g. "PackageA v1.2.0".

Came across this How to bundle run-time-only dependencies from NuGet packages in Inno Setup installer?, which is almost exactly I want but it seems the code doesn't work in my Inno Script.

Any help or suggestion as how to approach this?

Solution

You can define an Inno Setup preprocessor function that will resolve the directory file mask. Use FindFirst function for that:

#define FindFolder(Path) \
    Local[0] = FindFirst(Path, faDirectory), \
    Local[0] ? \
        AddBackslash(ExtractFileDir(Path)) + FindGetFileName(Local[0]) : Path

[Files]
Source: "{#FindFolder("..\packages\PackagesA*")}\*.*"; DestDir: "{app}"; \
    flags: recursesubdirs

If you add SaveToFile call to the end of the script:

#expr SaveToFile(AddBackslash(SourcePath) + "Preprocessed.iss")

... you will see that the above code resolves to:

[Files]
Source: "..\packages\PackageA1.2.0\*.*"; DestDir: "{app}"; flags: recursesubdirs

If no such folder is found, the code resolves to:

[Files]
Source: "..\packages\PackageA*\*.*"; DestDir: "{app}"; flags: recursesubdirs

... and the compiler will then fail with "No files found matching ...".
