Tup uses the backslash character in paths as an escape character, primarily to support filenames with spaces. Eg: an output of "foo bar" can be written as foo\ bar in the output section. To put an actual backslash in the path, you'd have to use \\, so the example should work with ..\\<submodgroup>
Note that tup should work fine on Windows when the subprocess uses files with backslash as the path separator. So both of the following should work: : |> cmd /c copy input foo\bar |> foo/bar : |> cmd /c copy input foo\bar2 |> foo\\bar2 I'm not sure about the difference between single and double-quotes, and I'm unable to reproduce it. Is that still causing a problem for you? -Mike On Tue, Jan 9, 2024 at 7:20 AM Peter Jaspers <[email protected]> wrote: > I found my mistake: I used backward slash instead of forward slash: > ..\<submodgroup> must be ../<submodgroup> > And for who wonders what " Het systeem kan het opgegeven bestand niet > vinden" means: it is Dutch for "The system can not find the given file". > > > Op maandag 8 januari 2024 om 15:43:23 UTC+1 schreef Peter Jaspers: > >> I tried to reproduce the %<group> example in the %-flags section of the >> tup manual >> on my Windows computer.
