Truncate or fold file paths if out of bounds

[vuki656]

Is your feature request related to a problem? Please describe.
Yes, in a large project, there are often deeply nested files leading to file paths going out of bounds and file names not being visible:

Here a part of the file name is cut off, and if there was another file 1 level deeper, its name wouldn't be visible at all. This makes it difficult to spot what you are looking for.

Describe the solution you'd like
Not 100% sure but either to truncate the file path if too long, or fold it.

Another potential solution to this would be to display only file names in the list and the path next to them, similarly to how IntelliJ does it.

Thanks for the amazing plugin!

Telescope find_files shorten_path=true but note there will be a overhaul of how the filepath display options work: #839 this will also be cool #886

For making it dynamic there is a little bit missing because currently we don't know the result window width, when we calculate the display string, but i have an idea how we could do this.

That helps, thanks. Although I'm still looking forward as to what they will come up with in #839.

Also, not sure if I'm doing something wrong, but when I launch Telescope find_files shorten_path=true it works as expected, but If I set it in the config like so it doesn't work. Am I doing something wrong?

require('telescope').setup{
    shorten_path=true
}

[Conni2461]

Yeah currently it doesn't work in the setup table (even tho the readme says so, no idea why it does in the first place) but #839 tries to fix this issue.

[vuki656]

Oh okay, feel free to close this issue if it's not going to be used for tracking as I would consider my problem solved.

Thanks for the help.

I am closing this now as path_display={"truncate"} has been implemented.

It should goes like this in config, if you dont know how to setup it:

require('telescope').setup{
	defaults = {
		path_display={"smart"} 
	}
}

Check:
:help telescope.setup()

Thanks, it worked with find_files! However I tried the setting with Telescope lsp_references, it doesn't seem to work.

[arnevm123]

I have the same issue aas @nicos68, this works for find_files, but not for lsp_references or git_status, did anyone find a solution for this?

Similar results to @nicos68

In the uses I've tested, it seems that some of the options ("smart", "shorten", etc)

Do work with

• builtin.buffers
• builtin.find_files
• builtin.live_grep

Do NOT work with

• builtin.oldfiles
• builtin.gitfiles

Perhaps there is something I haven't configured properly?

This is what I'm currently rocking in my init.lua:

  -- telescope
  {
    'nvim-telescope/telescope.nvim',
    config = function()
      require("telescope").setup({
        defaults = {
          layout_config = {
            vertical = {
              width = 0.95
            },
            horizontal = {
              width = 0.95
            },
          },
          path_display = {
            "shorten"
          },
        },
      })
    end
  },

Agree with this and also it doesn't work with extensions

Same here. Custom function for path_display works for builtin.find_files, but not for builtin.git_status.

[jamestrew]

I fixed the path_display option for git_status here #2881

I tested out oldfiles and git_files, but they appear to be working. Also looking at the code, they should work as well.

[sassanh]

@jamestrew is there a reason why path_truncate is not exposed in utils api?
Third parties and custom pickers would really benefit from it, specially considering it is using calc_result_length and it is too complicated and hacky for other developers to come to the conclusion they can achieve line length like that, I made it public for myself and now I can truncate paths in my custom picker like this:

utils.path_truncate(display_filename, 1, {})

I can't imagine how I could achieve this myself without reusing path_truncate
