Description of your pull request and other information

Various other applications and services embed youtube-dl and its forks, in way that may present error messages designed for direct users of youtube-dl to the users of such embedding applications and services. Since such users ran the embedding application or connected to the embedding service, they are generally not competent to respond to an error message that asks them to run youtube-dl with certain command-line options and therefore cannot be helped to solve the issue. They should instead turn to the support channel for the embedding application and service.

Examples: #30140, https://github.com/ytdl-org/youtube-dl/issues?q=is%3Aissue+telegram.

This PR rewords the default postfix message for errors to direct consumers of embedding applications and services away from the youtube-dl bug tracker and towards the support channel for the embedding application and service.

implying people will not just ignore it

🤦‍♂️

Indeed; that message is long enough as it is, my eyes already glaze over most of it. Better would be to modify the message to point to the issue tracker only in the CLI frontend (__main__), and then only if os.isatty(1) and os.isatty(2). And that’s assuming this pull request will be merged in the first place, which looks less likely by the day.

Also, while the error message itself is otherwise okay, the wording of the pull request title/commit description is rather unfortunate. You’re basically calling users idiots.

While that might sometimes be fair, 'competent' should be interpreted in the legal sense as 'having the jurisdiction, capacity and resources'. The embedded context typically denies that to the user.

point to the issue tracker only in the CLI frontend (main), ...

The embedder may be running the yt-dl program rather than a Python program that imports it.

and then only if os.isatty(1) and os.isatty(2)

Well, that may be a better idea, but wouldn't we like to tell the failing app about the error?

[fstirlitz]

Then tell it. Just don’t include the bug report instructions.
