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.

https://github.com/lambdalisue/fern.vim/wiki/Tips#perform-tcd-when-enterleave-only-in-drawer-style

[Shatur]

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.

[lambdalisue]

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)'

[lambdalisue]

That's why the PR said "partial". Please check #108 and give me your opinion. @Shatur95

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 ```vim nmap 1 (fern-action-debug) nmap 2 '(fern-action-debug)' nmap 3 '(fern-action-debug)' nmap 4 "(fern-action-debug)" nmap 5 '\(fern-action-debug)' nmap 6 "\(fern-action-debug)" ```

[lambdalisue]

I changed the way. Please check https://github.com/lambdalisue/fern.vim/pull/112 @Shatur95

[Shatur]

I like new way much more :) Tested, it works, but I have the same issue with cd. Here is the video, maybe I doing something wrong: (I missed \ for enter action, but it do not used on the video)

Only 2 does not work

Yes, also it looks like mappings to keyboard with <expr> works too:

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)'

[lambdalisue]

I'd love to classify the issue so please execute cd:root action and cd action directly (from hitting a) and see what happen.

Additionally, I guess that cd:root or cd does not work on your environment so please provide me your environment information (OS, Vim/Neovim, version, etc.)

Closed by #112

[Shatur]

You are right, the problem is in cd and cd:root command in my environment. I will test without any plugins first (except fern.vim) and then will open a new issue.

The last thing about current issue: I can automatically make a command to cd:root after Fern execution in my shortcut, but maybe add an option to cd to current root automatically on -reveal?

[Shatur]

I'm very sorry, the issue not in fern.vim at all. For some reason when opening a buffer from Startify :cd (even Ex command) do not affects to this opened buffer when executed in other buffer. Very strange.

[lambdalisue]

Then Startify may invoke :lcd or :tcd internally. Use tcd:root action instead then.

I tried, even :tcd Ex command not work :(

[Shatur]

I tried, even :tcd Ex command not work :(

I looked as Startify source code and it uses :lcd. After :lcd I can't change current directory for such buffers even with :tcd.

That's sad. But I understand that lcd is more specific than tcd....

Then probably you should maka an issue report on startify.
