Directory size

[tambourine-man]

Hi, I couldn't figure this out

K Shows file info. [count] shows directory size.

Hitting K over a file shows its size. When over a directory it shows “0.00K”.

Trying 1K (what I understand from [count] K) displays this error:

Error detected while processing function 27_info:
line 5:
E730: using List as a String
E484: Can't open file /var/folders/t3/n79wv4td5gd2z1by299ll1pc0000gn/T/vPtth4v/0

1K should work. Just tried it and it works for me on macOS, which it looks like you're using...

Looks like vim can't open temp files on your system...? That leads to weird problems, Vim uses temp files to run shell commands (weird but true).

[tambourine-man]

Weird. I opened Vim as root, similar issue.

Yes, I'm running a Mac, Mojave 10.14.6.
Nothing special about my installation as far I as I know:

vim --version VIM - Vi IMproved 8.2 (2019 Dec 12, compiled Aug 15 2020 20:27:49) macOS version

/usr/bin/vim --version VIM - Vi IMproved 8.0 (2016 Sep 12, compiled Jun 19 2019 19:08:44) Included patches: 1-503, 505-680, 682-1283, 1365 Compiled by [email protected]

I even tried with a barebones vimrc, with only set nocompatible.

Isn't necessarily a permissions issue. You need to figure out why Vim can't open temp files it created using the Vimscript tempname() function.

[tambourine-man]

This works:

let tmpFile = tempname()
exe "w " . tmpFile
exe "e " . tmpFile

Does the Dirvish issue go away if you (do this at the top of your vimrc, before Dirvish loads):

:set noshelltemp

[tambourine-man]

Nope :(
But I'm using Vim's own package manager (the pack/*/start directory), so I'm not sure it's actually running before Dirvish

[justinmk]

Oh, that's because in Vim system() does not respect 'shelltemp' (see :help 'shelltemp'). Nice.

Can you confirm this is failing (replace /path/to/dir/ with the directory path that you want to inspect):

:echo system(['du','-hs', '/path/to/file/'])

Then try this:

:echo system('du -hs /path/to/file/')

Actually I think this is a Dirvish bug because Vim doesn't support the list form. The tempfile error was a red herring.

[tambourine-man]

I think you nailed it.
This fails
:echo system(['du','-hs', '~/Desktop'])
This works
:echo system('du -hs ~/Desktop')

[tambourine-man]

Thanks a lot.
I should probably switch to nvim, but I still like the idea of being able to run my editor anywhere.

[justinmk]

Use whatever you like, but that trope always gets me so I must respond :) If you use vim 9 or 8.2 then that also is not "everywhere". Some systems have e.g. vim 7.x, and going back to vim 7.x from nvim is analogous to going from vim 8.x. This applies to any new version of vim.

BSDs don't ship with vim at all.

[tambourine-man]

I think Ubuntu 20 comes with 8.1, which is pretty recent, but it's a fair point.

Most of my .vimrc checks for feature support, so I'm used to the vim experience being on a spectrum while remaining mostly consistent, from 7.4 to 8.2, full MacVim.app to Terminal.app, “graceful degradation” style. But I guess this could be accomplished with nvim as well. I tend to prefer stock stuff whenever possible, it's usually simpler, but the thought of writing Lua instead of Vimscript is tantalizing.

Anyway, thanks again :)
