Question

I'm trying to create a keymap to jump to the current buffer in the MiniFiles navigation.
Usually, I open nvim in the root of my project, so, when using MiniFiles.open(), it opens the root directory. But when setting the current file as argument, it does not 'persist' the navigation when changing directories in Mini.

My idea would be to open Mini.Files on the root directory, with 'persistence', and have a keymap that updates the MiniFIles window to point to the current buffer (and updates the 'last used state' when the Mini window is closed).

vim.api.nvim_create_autocmd('User', {
  pattern = 'MiniFilesBufferCreate',
  callback = function(args)
    local mini_buf = args.data.buf_id
    local src_file = vim.api.nvim_buf_get_name(args.buf)

    vim.keymap.set('n', ',', function()
      MiniFiles.refresh({...}) -- How can I update the current position?
    end, { buffer = mini_buf, desc = 'Jump to current buffer' })
  end,
})

Sorry, I don't think I understand the issue/idea of "does not 'persist'" here. Could you elaborate about your use case with exact steps (preferably with screencast)?

Starting explorer with MiniFiles.open(vim.api.nvim_buf_get_name(0)) focuses on the current file in its parent directory. If you want to show it relative to current working directory (i.e. project root in this case), you can press @ to reveal current working directory. If you want that automated programmatically, there is reveal_cwd() function.

Thanks for the quick response. With persists, i meant that it keeps the 'last used state'.

Idea is as following: I want to open MiniFiles with MiniFiles.open() (no arguments), so that it opens in the cwd. And I want a keymap to be able to focus the current file in its parent directory.

That is relatively straightforward set_branch() and most effort is spent into getting the data for what is "current file" (i.e. the file for the buffer that is displayed in the window which was current when explorer opened). So something like this:

local focus_target_file = function()
  local target_window = MiniFiles.get_explorer_state().target_window
  local target_buf_id = vim.api.nvim_win_get_buf(target_window)
  local cur_filepath = vim.api.nvim_buf_get_name(target_buf_id)
  if vim.loop.fs_stat(cur_filepath) == nil then return vim.notify('Current buffer is not for file on disk') end

  MiniFiles.set_branch({ vim.fs.dirname(cur_filepath), cur_filepath })
end

vim.api.nvim_create_autocmd('User', {
  pattern = 'MiniFilesBufferCreate',
  callback = function(args)
    vim.keymap.set('n', ',', focus_target_file, { buffer = args.data.buf_id, desc = 'Focu on target file' })
  end,
})

Thanks a lot! That's exactly what I wanted!
It seems I didn't read the documentation for set_branch carefully enough.
Cheers! 👍
