The ability to automatically change current working directory

[Shatur]

NERDTree have the ability to automatically synchronize vim working directory with current root. Could you add an option for it in Fern? For example, change vim working directory on fern-action-leave, fern-action-enter, etc. and on reveal.

Probably, this tip helps you.

Thanks for the tip!
I tried it, but it not works as expected for me.
After performing this action I stay in the previous directory.
For example:

I would expect to stay in the drawer directory after cd.

Got it. It's a bit complicated than I thought and the tips does not work currently.
I'm working on this issue on #108 👍

[Shatur]

@lambdalisue, thanks! Should I use on of these commands in the tip above instead?

[lambdalisue]

I'll mention you once the PR become ready to test 👍

[Shatur]

Okay, thanks :)

I tried the following mappings, but this the directory still mapped to the previous dir. Am I using it ok?

nmap <buffer><expr> <S-k> '<Plug>(fern-action-leave)<Plug>(fern-action-cd:root)'
nmap <buffer><expr> <C-CR> '<Plug>(fern-action-enter)<Plug>(fern-action-cd:root)'

That's why the PR said "partial". Please check #108 and give me your opinion.

And actually your usage was wrong. You need to use " and escape <Plug> or <C-x> or soon with \ when you use string in mapping

Tested, works! But it looks like fern-action-cd:root changes directory only for current fern buffer. I would expect to change directory globally.

Did not know about it. I used the following mappings and it works as expected:

nmap <buffer><expr> m '<Plug>(fern-action-move)'
nmap <buffer><expr> r '<Plug>(fern-action-rename)'
nmap <buffer><expr> d '<Plug>(fern-action-trash)'
nmap <buffer><expr> y '<Plug>(fern-action-clipboard-copy)'
nmap <buffer><expr> c '<Plug>(fern-action-clipboard-move)'

Also, the following works too:

nmap <buffer><expr><silent> <S-k> '<Plug>(fern-action-leave):call fern#smart#ready("\<Plug>(fern-action-tcd:root)")<CR>'
nmap <buffer><expr><silent> <C-CR> '<Plug>(fern-action-enter):call fern#smart#ready("\<Plug>(fern-action-tcd:root)")<CR>'

Also, in documentation you have examples without ' and ". Is it a typo?

It's strange. I confirmed that cd action invoke :cd command and it change global cwd.
Are you sure that no :lcd or :tcd had applied? These command fix cwd on buffers.

Also, in documentation you have examples without ' and ". Is it a typo?

My bad. I didn't know that ' is accepted and \ escape is not required for <expr> mapping. These are required for :normal thus I mis-understood.

Only 2 does not work

  nmap <buffer> 1 <Plug>(fern-action-debug)
  nmap <buffer> 2 '<Plug>(fern-action-debug)'
  nmap <buffer><expr> 3 '<Plug>(fern-action-debug)'
  nmap <buffer><expr> 4 "<Plug>(fern-action-debug)"
  nmap <buffer><expr> 5 '\<Plug>(fern-action-debug)'
  nmap <buffer><expr> 6 "\<Plug>(fern-action-debug)"
