Elfeed Tube - Youtube on your terms

I am speechless. You've outdone yourself.

Impressive. I just might have to try it. I also hadn't seen [aio](https://github.com/karthink/elfeed-tube) before. It seems easier to use than [async.el](https://github.com/jwiegley/emacs-async).

I've just tried it and it works out of the box. Thank you very much.

Time to switch :)

Cool idea for a package. I got the following byte copilations warnings when installing on Emacs 29: elfeed-tube-contrib.el:33:38: Warning: Unused lexical variable `tx' elfeed-tube-contrib.el:35:25: Warning: Unused lexical variable `captions' elfeed-tube-contrib.el:42:25: Warning: Unused lexical variable `captions' elfeed-tube-contrib.el:25:41: Warning: ‘nreverse’ called with 0 args, but requires 1 elfeed-tube-contrib.el:25:41: Warning: ‘nreverse’ called with 0 arguments, but requires 1 elfeed-tube-contrib.el:27:41: Warning: ‘url-hexify-string’ called with 0 arguments, but requires 1-2 elfeed-tube-contrib.el:14:28: Warning: Unused lexical variable `st' elfeed-tube-contrib.el:14:31: Warning: Unused lexical variable `dt' elfeed-tube-contrib.el:24:37: Warning: the function ‘->’ is not known to be defined. elfeed-tube-contrib.el:19:32: Warning: the function ‘elfeed-tube-curl-enqueue’ is not known to be defined. elfeed-tube-contrib.el:36:49: Warning: the function ‘elfeed-tube--preprocess-captions’ is not known to be defined. elfeed-tube-mpv.el:41:11: Warning: Package vc-mtn is deprecated elfeed-tube-test.el:48:23: Warning: ‘system-name’ is an obsolete variable (as of 25.1); use (system-name) instead elfeed-tube-utils.el:41:53: Warning: Unused lexical argument `save' elfeed-tube-utils.el:207:30: Warning: attempt to inline ‘prophelp’ before it was defined elfeed-tube-utils.el:176:21: Warning: Unused lexical variable `author' elfeed-tube-utils.el:177:21: Warning: Unused lexical variable `feed' elfeed-tube-utils.el:237:14: Warning: Unused lexical variable `window' elfeed-tube-utils.el:261:10: Warning: Unused lexical variable `authors' elfeed-tube-utils.el:261:18: Warning: Unused lexical variable `feeds' elfeed-tube-utils.el:264:21: Warning: Unused lexical variable `author' elfeed-tube-utils.el:264:28: Warning: Unused lexical variable `query' elfeed-tube-utils.el:291:10: Warning: Unused lexical variable `authors' elfeed-tube-utils.el:291:18: Warning: Unused lexical variable `feeds' elfeed-tube-utils.el:293:19: Warning: Unused lexical variable `author' elfeed-tube-utils.el:293:26: Warning: Unused lexical variable `query' elfeed-tube-utils.el:207:30: Warning: the function ‘prophelp’ is not known to be defined. elfeed-tube.el:146:2: Warning: custom-declare-variable `elfeed-tube-auto-fetch-p' docstring wider than 80 characters elfeed-tube.el:324:16: Warning: variable ‘_’ not left unused elfeed-tube.el:361:25: Warning: Unused lexical variable `error' elfeed-tube.el:407:21: Warning: variable ‘_’ not left unused elfeed-tube.el:438:23: Warning: variable ‘_’ not left unused elfeed-tube.el:454:26: Warning: variable ‘_’ not left unused elfeed-tube.el:506:40: Warning: Unused lexical variable `dur' elfeed-tube.el:570:9: Warning: value returned from (format segment: %s elfeed-tube.el:564:35: Warning: Unused lexical argument `win' elfeed-tube.el:564:39: Warning: Unused lexical argument `obj' elfeed-tube.el:655:11: Warning: variable ‘_’ not left unused elfeed-tube.el:722:25: Warning: Unused lexical variable `error' elfeed-tube.el:767:17: Warning: Unused lexical variable `type' elfeed-tube.el:767:22: Warning: Unused lexical variable `time' elfeed-tube.el:914:25: Warning: reference to free variable ‘duraion’

Instead of providing the pair of `steup` and `teardown` functions, this could be implemented as a minor mode. Then users could just add `elfeed-tube-mode` to the `elfeed-show-mode` and/or `elfeed-search-mode` hooks.

Are you a wizard?

Thanks, I'm aware the byte compilation isn't clean yet. Will address these before submitting to MELPA.

The introductory blog post for aio is fantastic, too. It's actually what finally allowed me to make sense of async in JavaScript and Python.

That's really cool. Nice one karthink!

This was the original idea but it didn't fit some of the intended behavior, such as also fetching video metadata when running `elfeed-update`. It would have to be a global minor-mode. I've settled on this approach for now instead. `elfeed-tube-setup` does not need to run to use the functionality in this package, you can call `elfeed-tube-fetch` manually on a per-entry basis in Elfeed.

If I understand correctly, `async` is true multithreading for Emacs using child Emacs processes. `aio` is quite different, it's a (much) more convenient way of writing callbacks on the main event loop. It can't provide any actual async processing.

Which theme are you using ?

It's modus-vivendi, part of the modus-themes package.

I already have my YouTube subscriptions in elfeed via elfeed-protocol-ttrss, can I get them to open with elfeed-tube?

That certainly seems to be how it works, yes. I think `async` was made that way because it was the most straightforward way to do it. It has some benefits (namely actual multi-core use), but I've used it more for the concurrency it provides than the parallelism.

If I understand what `elfeed-protocol-ttrss` does correctly, elfeed-tube should work fine. All it needs is for Elfeed to be able to see the Youtube feed. However any video metadata you may save to your elfeed-db will not be synced back to tt-rss via elfeed-protocol.

Right, I was just confused since it threw an error and I didn't notice anything changing: Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) signal(wrong-type-argument (number-or-marker-p nil)) #f(compiled-function () #<bytecode -0x1a47d4fb57193062>)() #f(compiled-function (fetched-p) #<bytecode 0x15863fb8bc41fb12>) (#f(compiled-function () #<bytecode -0x1a47d4fb57193062>)) apply(#f(compiled-function (fetched-p) #<bytecode 0x15863fb8bc41fb12>) #f(compiled-function () #<bytecode -0x1a47d4fb57193062>)) timer-event-handler([t 25255 38796 82214 nil #f(compiled-function (fetched-p) #<bytecode 0x15863fb8bc41fb12>) (#f(compiled-function () #<bytecode -0x1a47d4fb57193062>)) nil 26000 nil])

Please raise an issue on the repo with more information if you have the time, I'd like to address this.

Awesome! Thanks for sharing.
