quickjs VS mpv

You can use it as en embedded scripting language within Python.

You could run the webextention javascript in quickjs.

I was interested to see that this uses the DukPy wrapper around Duktape for the JavaScript interpreter: https://browser.engineering/scripts.html

This made me start digging into whether this was considered a "safe" way of executing untrusted JavaScript in a sandbox.

its not completely clear to me if DukPy currently attempts safe evaluation - it's missing options for setting time or memory limits on executed code for example: https://github.com/amol-/dukpy

There's a QuickJS Python wrapper here which offers those limits: https://github.com/PetterS/quickjs

I'm pretty paranoid though any time it comes to security and dependencies written in C, so I'd love to see a Python wrapper around a JavaScript engine that has safe sandbox execution as a key goal plus an extensive track record to back it up!

https://mpv.io/ has yt-dlp support, if yt-dlp is installed you just need to throw the URL at it and it plays the video (without download).

See https://github.com/mpv-player/mpv/issues/9053

I apologise for not following procedure. I am in the middle of building mpv 0.37 from source. Irrespective of the outcome I will document what I had to do in addition to the instructions on mpv.io and if the problem perststs, where it happens and where not with kernel version, mpv version taken from the screen, and the terminal output.

Use MPV. Partticularily shinchiro's builds. Extract the folder where you want its installation directory to be, if you decide to install it. Otherwise, just drag and drop files on top of its window or executable.

Author of ripgrep here.

Like automatic encoding detection and transparently searching UTF-16?

Or simple ways for composing character classes, e.g., `[\pL&&\p{Greek}]` for all codepoints in the Greek script that are letters. Another favorite of mine is `\P{ascii}`, which will search for any codepoint that isn't in the ASCII subset.

Or more sophisticated filtering features that let you automatically respect things like gitignore rules.

Those are all things that ripgrep does that grep does not. So I do not favor this explanation personally.

ripgrep has just about all of the functionality that GNU grep does. I would say the two biggest missing pieces at this point are:

* POSIX locale support. (But this might be a feature[1].)

* Support for "basic" regexes or some equivalent that flips the escaping rules around. i.e., You need to write `\+` to match 1 or more things, where as `+` will just match `+ literally.

Otherwise, ripgrep has unfortunately grown just about as many flags as GNU grep.
