As far as I can tell std.process can only run commands in the working directory of the currently executing function. I want to execute a certain program inside a subdirectory on windows and can't get it to work:

myproject
 |- subdir

So my executable has "myproject" as working directory. And I want to execute "dmd" with "subdir" as working directory.

Isn't it possible to execute a command like "cd subdir && dmd"?

Thanks. That works. It still would be nice if std.process had this in its API.

this is a command use case. Further,relying on shell such as  cd subdir &&
foo is fragile: if it fails, we're not sure whether it's because it
couldn't cd to subdir or because of foo.

Woudl the following be as efficient?
system_in_dir(string dir, string action){
auto path=getcwd
scope(exit)
  chdir(path)
chdir(dir)
system(action)
}

Well at least the windows API call CreateProcess already has a parameter which you can use to specify the working directory. Its just not exposed in the implementation of std.process. I don't know how things are on linux though.
