autocomplete - how to implement a file name completion in Emacs -


recently, want make library operate windows registry.

the first thing want making input of registry key path easily. since looks file path, maybe can achieved methods read-file-name'? every time user input the/' , push key, can use `reg query' shell command next possible sub keys.

but how make in real emacs lisp code?

or maybe there full functional library?

you'll have write "completion-table" registry keys. don't think completion table exists in emacs. can use code of completion-file-name-table inspiration.
