Description of your issue, suggested solution and other information

Please allow the variables used with the -o flag (%(title)s , %(uploader)s , etc) to also be used with other flags such as
[deleted]
--download-archive
&tc.

It would make my life a whole lot easier.

Just parse JSON, we are not going to bloat the cli interface with all these commands.

I have literally no idea how to do that.

Here's what I'm trying to do:

https://stackoverflow.com/questions/36637319/youtube-dl-problems-scripting

I just want to put the archive file in the same folder as the channel that I'm downloading, but the --download-archive flag doesn't support any of the python vars used to create the folder/file name for the -o tag.

How would expanding the formatting support you already have to other output file arguments "bloat" the cli interface exactly?

Also what json should he be parsing and how would that solve the problem of putting the other output files in the same single location easily?

Bump.

You should better describe your issue. None of

--write-description
--write-info-json
--write-annotations

receive any parameters so -o-like template does not make any sense for them. I thought first your request is about adding --write-uploader etc. Still adding template support for --download-archive is bad idea.

My issue is that I'm downloading entire youtube channels to folders that are named via vars used with the -o flag. Since the --download-archive flag doesn't take any variables from the -o flag, I have to manually move them after the fact, which defeats the whole purpose of an automated script.
