They're all way too low contrast. There's a stream of theprimeagen spending way too long trying to find a good screenshot. (He finally manages to get one here.)

I don't know what the hell you used, but please for the love of your theme, don't disgrace it with these terrible screenshots. For the record, it looks great on my machine (and probably yours too).

This is my config:

use { "shaunsingh/oxocarbon.nvim", run = "./install.sh" }

I install successfully using :PackerSync but enabling the colourscheme displays the following error:

Before I made my changes, my c++ code wasn't being highlighted very well. Most noticeable were the lack of highlighting on the builtin types and the namespaces. This confused me at first as I thought that treesitter wasn't working.

After adding highlighting to builtin types and namespaces, the highlighting looks something like this:

I hope that this is an improvement that fixes something that just wasn't implemented and doesn't break some other language's highlighting.

Thanks for this amazing theme!

To reproduce:

1. remove everything that sets a colorscheme from your neovim config
2. run :colorscheme oxocarbon
3. run :colorscheme blue (or any other colorscheme)
4. run :colorscheme oxocarbon again

The first two colorscheme will work, but setting oxocarbon as colorscheme a second time does not work. This is relevant for some use cases where you want to change your colorscheme during runtime, for example styler or auto-dark-mode.

I checked, oxocarbon seems to be the only theme that has this issue, other themes, builtin or from the community, do not have this problem.

I have treesitter with typescript and tsx installed.

When I do this:

vim.cmd.colorscheme "oxocarbon"

I get incorrect colors:

But when I load a different theme first:

vim.cmd.colorscheme "everforest"
vim.cmd.colorscheme "oxocarbon"

I get correct colors:

Am I doing something wrong? It might have to do something with #4

Hey! Great colorscheme.

For some reason, a few days ago it started crashing nightly neovim for me. I'm using the AppImage version.

It crashes with the above message. With RUST_BACKTRACE=1, we get more verbosity.

fatal runtime error: Rust panics must be rethrown

Hi, I get this error when trying the theme with :colo oxocarbon.

E5113: Error while calling lua chunk: .../site/pack/packer/start/impatient.nvim/lua/impatient.lua:264: ...m/site/pack/packer/start

The theme has been installed, the install.sh script has been run by packer and I tried running it manually (it succeeded). Rust version is 1.62, neovim is latest head:

NVIM v0.8.0-dev-751-g8952def50

LuaJIT 2.1.0-beta3 

EDIT: Forgot to add, I'm on macOs Monterey, 12.3.1, Apple M1.

Only applying the colors to custom components (like "Section") and not for normal tags (like "div"): Obs: I don't know if it's a bug report or a feature request. Also, white for props/attributes doesn't seems right.

I'm running nvim version 0.9.0 installed from Brew

After setting the color theme to oxocarbon, neovim crashes with this message:

nvim(64121,0x1047ec580) malloc: *** error for object 0x1046886ae: pointer being freed was not allocated
nvim(64121,0x1047ec580) malloc: *** set a breakpoint in malloc_error_break to debug
zsh: abort
nvim init.lua

I'm assuming that this is due to the new nvim minor version. Just guessing that the native oxocarbon stuff was compiled against 0.8.*.

Hello, seems like oxocarbon.nvim does not set up any highlighting groups for diffs. This results in ugly (default) highlights in various plugins like neogit and diffview.

Also, CurSearch highlight is used for highlighting search result under the cursor - at the moment such search result gets no highlight at all. It could be as simple as linking it to IncSearch.

Could you please add those as well?

closes #22 and other crashes related to neovim 0.8

This was done by bumping the version of nvim-oxi dependency.

To make this backwards compatible and not cause breaking changes to those who already have a working version, the package now incorporates the same features as nvim-oxi. As for the installer, install.sh script was also updated to grab neovim's current minor release and match it with the corresponding feature to compile appropriately.

my config used lazy.nvim

local M = {
  "nyoom-engineering/oxocarbon.nvim",
  lazy = false,
  priority = 1000,
  enabled = function() return vim.g.theme == 'oxocarbon' end,
}

function M.config()
  require('oxocarbon').setup {
  }
  vim.cmd [[ colorscheme 'oxocarbon' ]]
end

return M

I am in love with the theme, I just have trouble reading comments because of the current gray in base03. The new value improves legibility while not standing out too much.

Currently the fold column is not visible. (If this is intentional please disregard)

I have included pull request with cyan;

NOTE: I have a few other tweaks on the way....

Hi, I just started using oxocarbon, both the dark and light versions and really like it. Thanks for this!

In the light version everything is great, however the LspReferenceText background is quite dark, I think it is base03=#161616. Not sure if this is a choice by design, but it really makes it difficult to see the text behind it many times:

I just want to know if this is a design choice, otherwise I can change it in my own config.

Thanks in advance!
