A small correction to the docs

[lkintact]

• I've verified that I'm running youtube-dl version 2020.07.28

At https://github.com/ytdl-org/youtube-dl/blob/master/README.md#output-template the template name playlist_index is said to be "padded with leading zeros according to the total length of the playlist". This doesn't happen however (perhaps was the case in the past, then changed and not reflected in the documentation?)

To check execute
youtube-dl --get-filename -o "[index %(playlist_index)d] %(title)s.%(ext)s" "https://www.youtube.com/watch?v=a0ul-BghOAs&list=OLAK5uy_kC4d8eCdL3QzEXEAoF97MMxJLP3f6M0n0", notice the indexes 1-9 aren't padded with zeroes.

@lkintact use %(playlist_index)s instead of %(playlist_index)d

[lkintact]

@s104346 Thank you, with s it worked as described.

I think it's "playlist_index (numeric)" in the documentation that confused me. Maybe since "playlist_index" only works as described if formatted as a string, it should listed as "playlist_index (string)"?

@remitamine What do you think about the suggestion in my post above?

[remitamine]

no, the data type of the value is an integer/numeric not a string. all the examples already use the syntax that I showed you here.
