How to show full file path in preview title

[rbhanot4739]

I want the preview title to show the full file path instead of just the file name. Is there a way I can do that ?

Give me a screenshot of where you want to see the preview title.

For example, if you look at the first screenshot in the repo, the file preview window title just shows the file name(profiler.lua).

So I want to show full path, i.e. lua/trouble/sources/profiler.lua in the preview window title on the right side.

The reason is that sometimes, when the path is longer than 40 chars, it gets truncated and it becomes difficult to figure out which directory the file is in.

Variant 1

picker = {
  sources = {
    files = {  
      on_change = function(picker, item)
        vim.schedule(function()
          picker.preview.win:set_title(item.file)
          -- WARN: `picker.preview:set_title(item.file)` doesn't work
        end)
      end,

picker = {
  sources = {
    files = {  
      on_change = function(picker, item)
        vim.schedule(function()
          picker.preview.title = item.file
          picker:update_titles()
        end)
      end,

Variant 2

For file preview

vim.schedule(function()
  local file = Snacks.picker.preview.file
  Snacks.picker.preview.file = function(ctx)
    local ret = file(ctx)
    if ctx.item.file then
      ctx.picker.preview:set_title(ctx.item.file)
    end
    return ret
  end
end)

For files source

picker = {
  sources = {
    files = {  
      preview = function(ctx)
        local res = Snacks.picker.preview.file(ctx)
        if ctx.item.file then
          ctx.picker.preview:set_title(ctx.item.file)
        end
        return res
      end,

Thank you @drowning-cat

I am trying to do a similar thing with a terminal window.
I have

local term = require'snacks.terminal'
term.open("ls", {win = {on_win = function(win) vim.schedule(function() win:set_title("list files") end) end}})

but this isn't working... Do you know what is wrong?

Bottom

Snacks.terminal('ls -la', {
  auto_close = false,
  win = {
    position = 'bottom',
    wo = { winbar = 'Hello B*tch' },
  },
})

Float

Snacks.terminal('ls -la', {
  auto_close = false,
  win = {
    border = 'single',
    on_win = function(win)
      vim.schedule(function()
        win:set_title 'list files'
      end)
    end,
  },
})

Yes thank you! I used the winbar option as a backup.
I there a reason why the win:set_title is not working for me when not a float? Is the title something different from the winbar?

[drowning-cat]

Because non-floating windows do not have titles in Neovim.
