Dired Flat File Listings (opens in new tab)

It turns out that if you call Dired from Elisp, you can pass it a list of files to display. Protesilaos Stavrou (Prot) leveraged that fact to write a bit of Elisp that provides him with a flat list of files matching a regular expression in a specified directory structure. His post has the code so you can see how he did it but it’s mostly what you’d expect: after some setup, he calls directory-file-recursively to gather the list of files that he then passes on to Dired.
