Steps to reproduce this bug using minimal vimrc

Open a Markdown file with the following contents:

*foo* ~bar~

Expected behavior

The text is italic and strikethrough, as shown in the tree-sitter-markdown readme

Actual behavior

The text is normal

[antoineco]

This looks like a terminal-related issue to me.

Here is how it looks in WezTerm for me:

I have this option set in my wezterm.lua, as well as the wezterm terminfo installed:

config.term = 'wezterm'

Reference: https://wezfurlong.org/wezterm/config/lua/config/term.html?h=tic#term-xterm-256color

[flexagoon]

@antoineco I am using Wezterm. Using the wezterm terminfo doesn't seem to help.

[flexagoon]

@antoineco are you sure you're using markdown+markdown_inline treesitter instead of regular syntax highlighting?

[antoineco]

Could you please hover the text that is supposed to be displayed as ~strikethrough~, execute :Inspect in Neovim, and share the result?

My output, for reference:

Same thing for italics:

[antoineco]

I do use Treesitter, but I'm also running Neovim's dev builds: NVIM v0.10.0-dev-2282+gabfcdd9bf. This could be making a major difference here. Let's see what your commands return.

[flexagoon]

Here:

Italic:

Strikethrough:

It seems like in my case they just link to regular @markup whereas on your screenshots they're linked to @markup.(italic|strikethrough)

[flexagoon]

In comparison, they are linked correctly when using the Catppuccin theme, and indeed, italic and strikethrough work with it:

[antoineco]

It could be because Catppuccin explicitly defines the @markup.italic and @markup.strikethrough groups, whereas we don't. I suspect that these may be built-in on Neovim's development branch, but not in v0.9. I need to investigate though. It should be relatively non intrusive to define them explicitly.

[antoineco]

Ok, I found why this is working out if the box on my build, those features made their way into Neovim in https://github.com/neovim/neovim/pull/27067

And the corresponding changes in Catppuccin: https://github.com/catppuccin/nvim/pull/630

[zirdl]

Any possible solutions for this? I have the same case with @flexagoon, only that I'm using Kitty

[flexagoon]

@zirdl btw I switched to Neovim nightly and the issue no longer happens for me, so you can do that if that's an option

Neovim nightly is available pre-built on AUR and Fedora COPR and Ubuntu PPA so it's not that hard to install

Thank you for this

[antoineco]

@zirdl like @flexagoon said, since nightlies already include that feature and Neovim 0.10 is likely to be released soon, I didn't feel pressed to implement this in the colorscheme.

I understand that Neovim 0.9 users may want to use the latest features from the Tree-sitter integration, so I'm going to add it now to Gruvbox Material.
