What were you trying to do (and why)?

Install a newer version of youtube-dl. Since a few years, only nightlies are offered for legal reasons, so there won't be any stable release soon.

What happened (include all command output)?

not available.

What did you expect to happen?

youtube-dl is offering nightlies, which are far superior to latest version offered by brew:
https://github.com/ytdl-org/ytdl-nightly/releases

They can't be used as is, since they are hard coded to work with python, not python3 (the only one supported on macOS 14), so they require to be re-compiled with that in mind.

A feature request has been already sent but brew.sh could do that instead:
ytdl-org/youtube-dl#30129 (comment)

Step-by-step reproduction instructions (by running brew commands)

not available.

Thanks for moving, didn't know where to put it.

I think we could accept a new youtube-dl-nightly formula. It's not a big deal that it is a nightly build, as long as it gets a tag. We might need to throttle the updates though because we might not be interested to run a daily rebuild on our side.

Looks like AUR already did this:
https://repology.org/project/youtube-dl-nightly/versions
https://repology.org/project/youtube-dl/versions

Regarding python; I did not read everything in detail but we can probably work around this with some shebang rewrite. We do that in other formulae.

And if there are some legal risks regarding shipping this package for homebrew: the @Homebrew/tsc might need to have a look at this

[superbonaci]

At least the website don't allow to download the latest stable:
https://ytdl-org.github.io/youtube-dl/download.html

$ curl -L https://yt-dl.org/downloads/latest/youtube-dl -o -

The shebang will have to be adapte for each macOS version, but at least latest macOS has python3 only, not python1 or python2, and I don't think should be a good idea have any as dependency, just use:

/opt/homebrew/bin/python3
/usr/local/bin/python3
/usr/bin/python3

Do we have any other formulae we've published nightly versions for?

It instead sounds to me like youtube-dl itself should probably be either updated to a random nightly version or just removed entirely if they are no longer tagging releases.

[superbonaci]

There's no difference in "quality" between nightlies and tagged releases, so just pick any nightly as your stable.
There are at least 5 nightlies already in brew.sh:

1. https://formulae.brew.sh/cask/1password@nightly
2. https://formulae.brew.sh/cask/adguard-vpn@nightly
3. https://formulae.brew.sh/cask/adguard@nightly
4. https://formulae.brew.sh/cask/arduino-ide@nightly
5. https://formulae.brew.sh/cask/brave-browser@nightly

[SMillerDev]

Those are casks (precompiled binaries) while youtube-dl is a formula (source build). There is only one formula that is sort of a nightly, it's luajit.

Emphasis on sort of. We follow upstream's version strategy now: http://luajit.org/status.html

@superbonaci I'd like to see an upstream citation before we rely on that, sorry.

Given --HEAD exists: I am even less inclined to introduce a youtube-dl-nightly now.

Something recent Debian/Ubuntu/etc has done instead is just replace phase out youtube-dl entirely in favour of yt-dlp.

We've already deprecated youtube-dl ourselves, though we don't currently point yt-dlp in that deprecation message.

Looks like AUR already did this

AUR ships many git snapshot packages - their policies are quite different. However even they didn't replace youtube-dl regular with it.

The only package that has updated the main package to something newer is Fedora, though they use git snapshots instead of nightlies and still recommend using yt-dlp instead

If it's deprecated: let's not make any more changes.
