Operating system

Linux (Fedora)

Terminal emulator / GUI

Ptyxis

Describe the bug

Contrary to what can be seen in the image present in the README, the three backticks are displayed above and below the code block at all times.

Expected behavior

In normal mode the backticks are hidden.

Additional information

Here's what it looks like in normal mode: Here's what the README shows:

Your screenshot is the result of having concealing disabled.

Did you configure the plugin with a different rendered conceallevel? 3 is the default.

[sandmuel]

Nope, just the default config. I have the following located within ./lua/plugins/markdown.lua

return {
    'MeanderingProgrammer/markdown.nvim',
    name = 'render-markdown', -- Only needed if you have another plugin named markdown.nvim
    dependencies = {
        'nvim-treesitter/nvim-treesitter', -- Mandatory
        'nvim-tree/nvim-web-devicons', -- Optional but recommended
    },
    config = function()
        require('render-markdown').setup({})
    end,
}

I have also tried setting it specifically to 3 in case there was some issue with the default, same results though.

return {
    'MeanderingProgrammer/markdown.nvim',
    name = 'render-markdown', -- Only needed if you have another plugin named markdown.nvim
    dependencies = {
        'nvim-treesitter/nvim-treesitter', -- Mandatory
        'nvim-tree/nvim-web-devicons', -- Optional but recommended
    },
    config = function()
        require('render-markdown').setup({
            win_options = {
                conceallevel = {
                    rendered = 3
                }
            }
        })
    end,
}

Huh, that's strange, I wouldn't expect any difference in what gets concealed.

There's a couple things it could be, I'm seeing that your rust code is not syntax highlighted so it could also be that you do not have highlights enabled with treesitter.

Can you run :checkhealth render-markdown and paste the result.

[sandmuel]

render-markdown: require("render-markdown.health").check()

markdown.nvim [nvim-treesitter] ~
- OK installed
- OK markdown: parser installed
- OK markdown_inline: parser installed
- WARNING latex: parser not installed
  - ADVICE:
    - If you do not want LaTeX support avoid this warning by setting { latex_enabled = false }
- ERROR highlights not enabled

markdown.nvim [executables] ~
- WARNING latex2text: not installed
  - ADVICE:
    - If you do not want LaTeX support avoid this warning by setting { latex_enabled = false }

markdown.nvim [configuration] ~
- OK valid

[sandmuel]

Seems the issue was in fact treesitter lacking highlights, creating ./plugins/treesitter.lua with the following did the trick:

return {
    "nvim-treesitter/nvim-treesitter",
    config = function()
        require'nvim-treesitter.configs'.setup {
            highlight = {
                enable = true,
                additional_vim_regex_highlighting = false,
            },
        }
    end,
}

Shall I close this issue?

Awesome glad it's working!
