Removing eob signs in buffer

[asmodeus812]

Description

I would like to be able to clear the eob sign characters in the nvim tree buffer. Using auto command does not seem to work, and i have been facing this issue for quite some time without any progress.

Neovim version

NVIM v0.7.2
Build type: Release
LuaJIT 2.1.0-beta3
Compiled by runner@fv-az164-457

Features: +acl +iconv +tui

Operating system and version

wsl, ubuntu 20

nvim-tree version

master

Minimal config

None, using defaults, with empty setup call.

Steps to reproduce

      augroup NVIMTREE
        autocmd!
        autocmd Filetype NvimTree setlocal fillchars=eob:\ ,fold:=
      augroup END

Expected behavior

Eob characters should be cleared for the nvim tree buffer

Actual behavior

Eob characters are still visible in the buffer.

Autocommands are not particularly reliable due to inconsistent event ordering.

Try using the event API:

local Api = require('nvim-tree.api')
local Event = require('nvim-tree.api').events.Event

Api.events.subscribe(Event.TreeOpen, function()
	vim.opt_local.fillchars="eob: "
end)

Seems to work fine, is that event called each time the tree is expanded/opened, is the buffer of the tree killed each time we toggle the tree off or is it just hidden, and the window pane is what gets destroyed ?

Another question is can that not be part of the other view properties on the tree config ? Like linenumber etc ?

[alex-courtis]

The buffer is destroyed whenever the tree is closed or its window is closed.

Another question is can that not be part of the other view properties on the tree config ? Like linenumber etc ?

It's a very niche requirement, and the configuration would become very cluttered if we included every posible option.

The event exists for such niche use cases.
