Possible to use conditional filenames?

[KonoVitoDa]

I would like to use different file name patterns, depending on given conditions. It is possible? Or will it be someday?

Conditional filenames are now possible with 4cf4043. Not sure if this is the best or a good way of doing it, but for now you set the default filename like before with the filename option, and everything that depends on a condition with filename-conditions:

    "sitename": {
        "filename": "default filename",
        "filename-conditions": {
            "extension == 'mp4'": "video filename",
            "len(title) < 16"   : "some other filename"
        }
    }

I've also considered combining the two into just the regular filename option like the following. It looks cleaner here, but the underlying code it more awkward.

    "sitename": {
        "filename": {
            "extension == 'mp4'": "video filename",
            "len(title) < 16"   : "some other filename",
            "": "default filename"
        }
    }

Let me know if this is OK like this or how I should change things.

Update: I changed it to the second example from #1394 (comment), i.e. filename-conditions got dropped and everything is done with just filename.
