Local config file doesn't use environment variables

[oschrenk]

I want to write every video to the same output directory. I put

-o "$HOME/Downloads/%(title)s-%(id)s.%(ext)s"

but instead of writing to ~/Downloads/ files are written to <cwd>/$HOME/Downloads. It seems that environment variables are not expanded.

Since #1639 was closed, you can use "~/Downloads/%(title)s-%(id)s.%(ext)s"in the config file and it will be replace with your home directory.

Since youtube-dl is not a shell script, it is not really feasible for it to expand environment variables. However, like many programs, it does expand tilde user names, as @jaimeMF suggested.
