How do I run a script for multiple files/glob input?

[Gremious]

I have a folder with a few videos and I wanna occatinally run ffmpeg to extract their audio.

./script.nu *.mp4 doesn't work, it says paramtere missing

nu script.nu *.mp4 auto expands and now my funciton is expected to take in a specific number of string, not even a list or antying

I would pass in a glob string but
a) it's annoyting to have to quote every time and
b) The docs says that I'm supposed to use into glob to convert from string but that doesn't seem to work:

┌in ~\test
└❯ glob *.mp4
╭───┬──────────────────────────────────────────╮
│ 0 │ C:\Users\Gremious\test\angry_dog_265.mp4 │
│ 1 │ C:\Users\Gremious\test\who is nl.mp4     │
╰───┴──────────────────────────────────────────╯

............................[04:40:25 PM] [took 1ms]............................

┌in ~\test
└❯ '*.mp4' | into glob
*.mp4

Please, how do I just provide my script a glob/an arbitrary number of files and run ffmpeg -i $input -vn -acodec copy $input on all of them?

i think the thing you are looking for is ...:

def main [...files] {
  print $files
}

->

$ ./test.nu *.txt
╭───┬───────────────────╮
│ 0 │ a.txt             │
│ 1 │ en_wos_nu.txt     │
│ 2 │ english.txt       │
│ 3 │ viewerlist.txt    │
╰───┴───────────────────╯

glob is a datatype like path, date, etc. | into glob changes a string into this filetype and does not expand it.

when passing aruments to a external command (or script), which does not have a definition nu expands globs (*.txt -> multiple arguments) in order to be backwards-compatible with POSIX (and generally easier to use). when defining a nushell function you have to define each argument and expanded globs are multiple arguments. therefore a single basic argument defined in nushell just accepts 1 argument (file). the ... says "accept any amount and put it into a list".
