F＃FAKE WixHelper使用fileFilter

Question

Looking at the WixHelper for F# documentation it looks like I can pass in a -filter parameter. I am still learning F# and I can't figure out how this method is supposed to work.

https://github.com/fsharp/FAKE/blob/master/src/app/FakeLib/WiXHelper.fs#L60-60

METHOD

wixDir fileFilter asSubDir directoryInfo

I am trying to adapt this call to filter out *.exe (I do not want to include them).

 wixDir (fun file -> true) true (DirectoryInfo (buildDir @@ "/SetupFiles"))

You just need to change (fun file -> true) to only return true when the file doesn't end with ".exe" I assume file is a FileInfo , so you would check if the file extension is "exe". I haven't tested this, but it should be something like this:

(fun file -> not (file.Extension = ".exe"))
