Opening DiffViewFileHistory without Folds

[harrisoncramer]

First off, thank you for the awesome plugin, I use it regularly.

Is it possible to configure the :DiffviewFileHistory command to open the diffs without folds? There's a similar discussion about Vim's built-in diff functionality here which is the same functionality that I'm hoping to accomplish.

Hopping into each buffer and running zR to expand them every time I switch a entry in the history isn't really a practical way of accomplishing this. Thanks again!

There was a problem with the order in which hooks were called before, but after the latest commit you should be able to do something like:

require("diffview").setup({
  hooks = {
    diff_buf_read = function(bufnr)
      vim.cmd("norm! gg]ckzt") -- Set cursor on the first hunk
    end,
    diff_buf_win_enter = function(bufnr)
      vim.opt_local.foldlevel = 99
    end,
  },
})

If you only want it to apply to file history views, you could do:

diff_buf_win_enter = function(bufnr)
  local FileHistoryView = require("diffview.views.file_history.file_history_view").FileHistoryView
  local view = require("diffview.lib").get_current_view()
  if view and view:instanceof(FileHistoryView) then
    vim.opt_local.foldlevel = 99
  end
end

You could obviously also do vim.opt_local.foldenable = false if you want to disable folds entirely in those windows.

Although, I have to ask: what is the point of this? In large files this will show a lot of irrelevant information, no?

This works great, apologies I didn't see this notification. Thank you!

I can't seem to get this to work, is it possible that I have some local plugin that might be overriding the hooks? I'm trying the following:

require("diffview").setup({
    enhanced_diff_hl = true,
    hooks = {
        diff_buf_read = function(bufnr) 
            vim.opt_local.foldlevel = 99
            vim.opt_local.foldenable = false
        end,
        diff_buf_win_enter = function(bufnr) 
            vim.opt_local.foldlevel = 99
            vim.opt_local.foldenable = false
        end
    }
})

And I'm still seeing folds when using :DiffviewFileHistory.

@norbertkeri Sorry, there was a regression related to the order of execution for hooks after a recent refactor. I just fixed this in the latest commit. Setting local options from these hooks should work as expected now.

No worries, works perfect now, thank you!
