Not running on save. Did I skip a step?

[coolaj86]

1. I've installed shfmt:

   curl -sS https://webinstall.dev/shfmt | bash
   

2. I've installed vim-shfmt in the vim 8 plugin style:

   mkdir -p ~/.vim/pack/plugins/start/
   git clone --depth=1 https://github.com/z0mbix/vim-shfmt.git ~/.vim/pack/plugins/start/shfmt
   

3. I've created a file with the options I want:

   ~/vim/plugins/shfmt.vim
   let g:shfmt_extra_args = '-i 4 -sr -s'
   let g:shfmt_fmt_on_save = 1
   

4. I've sourced that file in my ~/.vimrc:

   " Shfmt: TODO add to Webi
   source ~/.vim/plugins/shfmt.vim
   

Now if I run :Shfmt I can see that it indents, but it's not indenting on save.

What have I misunderstood or done wrong?

Are your settings actually in ~/vim/plugins/shfmt.vim or was that a typo?

also, is the file you’re editing detected as a shell script (filetype sh)?
