Extension working but images are not showing

Hi, I just installed the extension, everything seems to be working, I have no errors but the images are not showing on the right panel, I got no preview. See :

this can be caused by any of 3 2 reasons:

• You haven't installed rg (though i would personally recommend fd here) or you are missing any of the mentioned dependencies required to render images. scratch that, your image shows that files were found
• You are trying to use Ueberzug (the very core this plugin relies on), which has been discontinued and removed from pip/github/etc.
• You are trying to use this plugin on a Mac

I have an alternative in the works (that also works on OSX), but I need to refine it a bit still with proper image scaling, you can find it here: https://github.com/nvim-telescope/telescope-media-files.nvim/pull/35

you can import it as:

Plug 'HendrikPetertje/telescope-media-files.nvim', { 'branch': 'fix-replace-ueber-with-viu' }

or

use({ 
  "HendrikPetertje/telescope-media-files.nvim",
  branh = "fix-replace-ueber-with-viu"
  requires = { { "nvim-lua/popup.nvim" } } 
})

(make sure to install VIU as per instructions on https://github.com/nvim-telescope/telescope-media-files.nvim/blob/26cf84d25007544140a835c0644728e7a7e57d43/README.md)

My dotfile configuration for comparison: https://git.hendrikpeter.net/hendrikpeter/pico-vim/-/blob/master/lua/peva/telescope.lua

(notice that on line 40 i call for the media-search specifically.. these image and video searches are not bundled in to the default git_files or find_files)

Hi, I've tried to use it but I still get an error, please see (actually testing on my mac, not on my linux) : (Not supported)

What I've done :

Installing the plugin with your branch :

use({
    "HendrikPetertje/telescope-media-files.nvim",
         branh = "fix-replace-ueber-with-viu",
    requires = { { "nvim-lua/popup.nvim" } },
})

Installing viu :

tried with cargo, tried with brew too. viu is working with cli , see :

My configuration for telescope (tried to follow yours) :

local telescope = require("telescope")
local actions = require("telescope.actions")

if not telescope then
    return
end

if not actions then
    return
end
local function is_git_repo()
  local is_repo = vim.fn.system("git rev-parse --is-inside-work-tree")
  return vim.v.shell_error == 0
end

telescope.setup({
    defaults = {
        file_ignore_patterns = {
            ".git/",
            "node_modules/*",
        },
        mappings = {
            i = {
                ["<C-j>"] = actions.move_selection_next,
                ["<C-k>"] = actions.move_selection_previous,
                ["<Tab>"] = actions.toggle_selection + actions.move_selection_worse,
                ["<S-Tab>"] = actions.toggle_selection + actions.move_selection_better,
            },
            n = {
                ["<Tab>"] = actions.toggle_selection + actions.move_selection_worse,
                ["<S-Tab>"] = actions.toggle_selection + actions.move_selection_better,
            },
        },
    },
    extensions = {
        media_files = {
            -- filetypes whitelist
            filetypes = { "png", "webp", "jpg", "jpeg", "gif", "mp4", "pdf" },
        },
    },
    pickers = {
        find_files = {
            theme = "dropdown",
            previewer = false,
        },
        buffers = {
            theme = "dropdown",
            previewer = false,
        },
    },
})
telescope.load_extension("media_files")

vim.keymap.set(
  'n', 
  '<leader>,', 
  function()

    if (is_git_repo()) then
      builtin.git_files()
    else
      builtin.find_files()
    end
  end
, {})

vim.keymap.set('n', '<leader>mf', telescope.extensions.media_files.media_files, {})

thanks for the reply @ls-devs, I removed the "not supported" warnings early on in my pull request (which where initially there to stop OSX users from using the app) and made them a lot more verbose in my pull request later on. are you sure that you cleaned the old repo up from your packer cache before installing mine?

I didn't, but now even after cleaning cache and reinstalling I still get this error on OSX. On my Linux, I have no errors, but the image is not displayed on the right panel too (viu cli works on my linux too I can see the image displayed in terminal). Thanks for taking your time helping.

[HendrikPetertje]

i pushed a little fix up to always render in blocks. i noticed on Iterm and on my gnome terminal that nothing was being rendered when i was outside tmux... it can't fit images in.

it's odd that you are getting this error, I don't think there is any code left in the bash script that could echo that error to the console view in the preview window 😅

[ls-devs]

So how did you manage to make it work on your presentation ?

Can't see any new commit on your repository, where did you push your fix ?

[HendrikPetertje]

I'll try to run it with your config in a while. mine seems to be working fine, pushed additional things, but that is not fixing your issue i think (just resizing)

If you want to see the full config you can visit my nvim setup repository. Thank you for helping 👍🏼

[HendrikPetertje]

I ran your full config and I can reproduce your whoes!

it looks like when telescope-media-files gets pulled down that it just completely ignores the branch setting.

Everything starts working when i manually checkout to the correct branch, that's not really a desirable option though, I'm still on the Plug side of things, you might do some research to see if you can force packer to use the right branch.

(side-note: interesting choice to put leader on space-bar, took me a while to figure that one out :p)

Wow ! A huge thank ! I never would have thought to check this... It works now, but as you said, the image is not really well sized.

Forgot to mention I use the space-bar, I learned nvim this way !

(side-note: writing this, I discovered why packer didn't use the right branch, Ii'm gonna let you find out in the next code ahah

use({
    "HendrikPetertje/telescope-media-files.nvim",

    })

branh 🥇

small thing after my changes today. I switched from VIU to "chafa" as it is much better at putting things in the center and more importantly it uses glyphs with background/foreground colouring to make higher res images https://github.com/nvim-telescope/telescope-media-files.nvim/pull/35#issuecomment-1368915792

so since you've been testing with viu you might get some breaking changes (or warnings to install a picture lib) chafa is available on homebrew.

[ls-devs]

@HendrikPetertje Installed chafa, it's working of course, but can't get the image to display correctly. Please see :

Original image :

[HendrikPetertje]

it turns images in to ASCII art at the capability of the terminal you are working in (an inline terminal inside a vim popup) as shown here https://hpjansson.org/chafa/ when displaying an image it's not going to be able to represent each little detail (especially small text) perfectly as it does a best effort of turning the picture into ascii art
