How to pass variable length of arguments to other commands #7758
Description
Question
Hi, I really like nushell and would like to use it for my daily shell, but I met some problems when I am trying to create some aliases in nushell, specifically - how to create an alias that accepts variable parameters. Could anyone help me take a look?
It might be a dumb question, but I am kinda stuck. I did some searches and have tried several ways below to do it, but none of them works.
First, I tried to use alias keyword (https://www.nushell.sh/book/aliases.html#aliases):
C:\Users\r12f\Downloads〉alias ll = (ls -l) 01/14/2023 10:56:56 PM
C:\Users\r12f\Downloads〉ll *.zip 01/14/2023 11:00:21 PMError: nu::parser::parse_mismatch (link)
× Parse mismatch during operation.
╭─[entry #58:1:1]
1 │ ll *.zip
· ──┬──
· ╰── expected operator
╰────
Then I have tried to use custom commands with rest parameters (https://www.nushell.sh/book/custom_commands.html#rest-parameters):
C:\Users\r12f\Downloads〉def lsl [...x] { ls -l $x } 01/14/2023 10:55:56 PMC:\Users\r12f\Downloads〉lsl *.zip 01/14/2023 10:56:52 PM
Error: nu::shell::cant_convert (link)
× Can't convert to string.
╭─[entry #55:1:1]
1 │ def lsl [...x] { ls -l $x }
· ─┬
· ╰── can't convert list<string> to string
╰────
With some searches, I found a few threads discussing similar things (e.g. #1716), so I have also tried the syntax there, but it looks like the syntax is already changed:
C:\Users\r12f\Downloads〉alias ll [x...] { ls -l $x } 01/14/2023 11:00:23 PMError: nu::parser::assignment_mismatch (link)
× alias missing sign
╭─[entry #59:1:1]
1 │ alias ll [x...] { ls -l $x }
· ───┬──
· ╰── missing equal sign
╰────
So I am wondering what would be the right way to do it and is there any doc for this?
Really appreciate for the help in advance!
