How to setup diff view colorscheme like the one in the readme (the screenshot)?

[gaoxiaoliangz]

I know it's not an issue of the project, but I really can't find any place to discuss this. The diff view in the screen shot looks really cool. Especially the diff color schemes.

vim diff highlight groups are DiffAdd, DiffDelete, DiffChange and DiffText. And I noticed that in the screenshot, the DiffAdd are rendered as red on the left, just like what vscode does. On the right side it's bluish.

Is there any config reference you can provide, so that I can achieve the same diff color scheme?

I am also curious about the specific values set for the fg/bg of the highlight group. I'm currently setting them in the diff_buf_win_enter hook but cannot get the values to match.

@gaoxiaoliangz I was able to figure it out. The example in the screenshot is just using the existing hl group provided by the tokyonight theme (I believe the 'night' variation specifically). In my case, I was already using this theme but the hl groups and a few other background-related colors were not showing up right due to my use of tmux. If that's what's happening to you, try disabling tmux and viewing the diff.

Thanks for opening this, I was wondering the same thing. I use gruvbox, but want to figure out how to get those fancy empty line symbols. Mine show up as ugly -----!

@jamesgour You can try this vim.opt.fillchars:append("diff:╱")

Thanks @gaoxiaoliangz, that's pretty close! Doesn't look exact on my terminal but maybe it's because I'm using Wezterm :D

Hey! Based on @jdela22 comments above, I manually changed my colors to follow the tokyonight color schemes for the diff sections in my init.lua:

vim.api.nvim_set_hl(0, "DiffAdd", {bg = "#20303b"})
vim.api.nvim_set_hl(0, "DiffDelete", {bg = "#37222c"})
vim.api.nvim_set_hl(0, "DiffChange", {bg = "#1f2231"})
vim.api.nvim_set_hl(0, "DiffText", {bg = "#394b70"})

Just posting it here as a reference if anyone want to copy paste!

This is what I have in my highlights configuration:

vim.api.nvim_set_hl(0, 'DiffAdd', { bg = '#34462F' })
vim.api.nvim_set_hl(0, 'DiffDelete', { bg = '#462F2F' })
vim.api.nvim_set_hl(0, 'DiffChange', { bg = '#2F4146' })
vim.api.nvim_set_hl(0, 'DiffText', { bg = '#463C2F' })

vim.api.nvim_set_hl(0, 'DiffAdded', { fg = colors[3], bold = true })
vim.api.nvim_set_hl(0, 'DiffRemoved', { fg = colors[2], bold = true })
vim.api.nvim_set_hl(0, 'DiffChanged', { fg = colors[4], bold = true })

vim.api.nvim_set_hl(0, 'DiffviewWinSeparator', { fg = colors[9] })
vim.api.nvim_set_hl(0, 'DiffviewDiffDelete', { fg = colors[9] })
vim.api.nvim_set_hl(0, 'DiffviewFilePanelSelected', { fg = colors[6] })

vim.api.nvim_set_hl(0, 'DiffviewStatusAdded', { fg = colors[3], bold = true })
vim.api.nvim_set_hl(0, 'DiffviewStatusUntracked', { fg = colors[8], bold = true })
vim.api.nvim_set_hl(0, 'DiffviewStatusModified', { fg = colors[4], bold = true })
vim.api.nvim_set_hl(0, 'DiffviewStatusRenamed', { fg = colors[3], bold = true })
vim.api.nvim_set_hl(0, 'DiffviewStatusDeleted', { fg = colors[2], bold = true })
vim.api.nvim_set_hl(0, 'DiffviewStatusIgnored', { fg = colors[9], bold = true })

vim.api.nvim_set_hl(0, 'DiffAdd', { bg = '#34462F' })
vim.api.nvim_set_hl(0, 'DiffDelete', { bg = '#462F2F' })
vim.api.nvim_set_hl(0, 'DiffChange', { bg = '#2F4146' })
vim.api.nvim_set_hl(0, 'DiffText', { bg = '#463C2F' })

These are not the colors from the image tho... But also nice.

I was looking for this exact discussion lol. The whole neovim environment in the screenshot looks so good!

Can someone point to what's being used? i.e. Statusbar, Tabsbar, fonts, theme (judging from the discussion, it seems to be TokyoNight-Night), etc.?

I have diffview installed and running off the supplied configuration in the readme but it looks no where near what it looks like in the screenshot lol. I'm still pretty new to neovim so any pointers would be greatly appreciated!!

Based on these lines

diffview.nvim/lua/diffview/hl.lua

Lines 465 to 468 in 4516612

	DiffAdd = "DiffAdd",
	DiffDelete = "DiffDelete",
	DiffChange = "DiffChange",
	DiffText = "DiffText",

I believe, it should be possible to customize this way

vim.api.nvim_set_hl(0, 'DiffAdd', { ... })
vim.api.nvim_set_hl(0, 'DiffDelete', { ... })
vim.api.nvim_set_hl(0, 'DiffChange', { ... })
vim.api.nvim_set_hl(0, 'DiffText', { ... })

or you might try

vim.api.nvim_set_hl(0, 'DiffviewDiffAdd', { ... })
vim.api.nvim_set_hl(0, 'DiffviewDiffDelete', { ... })
vim.api.nvim_set_hl(0, 'DiffviewDiffChange', { ... })
vim.api.nvim_set_hl(0, 'DiffviewDiffText', { ... })
