[Bug] File not reloaded after using ’restore_entry‘

[ycycyyc]

Description

When I use DiffViewOpen to open the panel, and then want to roll back the modification through restore_entry, the corresponding file is not reloaded.

Expected behavior

Like the vim-fugitive plugin, pressing the X key can roll back the modification of the file and take effect immediately.

Actual behavior

File modifications are not rolled back.

Steps to reproduce

1. create a file and initialize the git repository

   
   package main

import "fmt"

func main() { fmt.Println("hello") }

2. add a new line and save:

package main

import "fmt"

func main() { // new line here fmt.Println("hello") }

3. :DiffviewOpen
4. Restore this file by pressing the "X" key
5. :DiffviewClose
6.  It's strange that the newly added line was not rolled back.
7. If I save the file directly, there is a warning message:

WARNING: The file has been changed since reading it!!! Do you really want to write to it (y/n)?

 The extra line only disappears when I press ':e<cr>'.

By default nvim doesn't automatically reload files that have been changed externally. You can make it do that with a simple auto command:

vim.api.nvim_create_autocmd({ "BufEnter", "CursorHold" }, {
  -- Automatically reload file if it's been changed externally.
  command = "silent! checktime %",
})
