fix(conflict)!: change default nav keymaps from ]x/[x to ]c/[c (#132) 
## Problem

The default conflict navigation keymaps `]x`/`[x` are non-standard. Vim
natively uses `]c`/`[c` for diff navigation, so the same keys are far
more
intuitive for conflict jumping.

## Solution

Change the defaults for `conflict.keymaps.next` and
`conflict.keymaps.prev`
to `]c` and `[c`. This is a breaking change for users relying on the
previous
defaults without explicit configuration.

*diffs.nvim.txt* Syntax highlighting for diffs in Neovim
Author: Barrett Ruth <br.barrettruth@gmail.com>
License: MIT
==============================================================================
INTRODUCTION *diffs.nvim*
diffs.nvim adds syntax highlighting to diff views. It overlays language-aware
highlights on top of default diff highlighting in vim-fugitive, Neogit, and
Neovim's built-in diff mode.
Features: ~
- Syntax highlighting in |:Git| summary diffs and commit detail views
- Diff header highlighting (`diff --git`, `index`, `---`, `+++`)
- Syntax highlighting in |:Gdiffsplit| / |:Gvdiffsplit| side-by-side diffs
- |:Gdiff| command for unified diff against any git revision
- Background-only diff colors for any `&diff` buffer (vimdiff, diffthis, etc.)
- Vim syntax fallback for languages without a treesitter parser
- Blended diff background colors that preserve syntax visibility
- Optional diff prefix (`+`/`-`/` `) concealment
- Gutter (line number) highlighting
- Inline merge conflict marker detection, highlighting, and resolution
==============================================================================
REQUIREMENTS *diffs-requirements*
- Neovim 0.9.0+
- vim-fugitive (https://github.com/tpope/vim-fugitive) (optional, for unified
diff syntax highlighting in |:Git| and commit views)
- Treesitter parsers for languages you want highlighted
Note: The diff mode feature (background-only colors for |:diffthis|, vimdiff,
etc.) works without vim-fugitive.
==============================================================================
SETUP *diffs-setup*
Install with lazy.nvim: >lua
{
'barrettruth/diffs.nvim',
dependencies = { 'tpope/vim-fugitive' },
}
<
The plugin works automatically with no configuration required. For
customization, see |diffs-config|.
==============================================================================
CONFIGURATION *diffs-config*
Configuration is done via `vim.g.diffs`. Set this before the plugin loads:
>lua
vim.g.diffs = {
debug = false,
hide_prefix = false,
fugitive = false,
neogit = false,
extra_filetypes = {},
highlights = {
background = true,
gutter = true,
blend_alpha = 0.6,
context = {
enabled = true,
lines = 25,
},
treesitter = {
enabled = true,
max_lines = 500,
},
vim = {
enabled = false,
max_lines = 200,
},
intra = {
enabled = true,
algorithm = 'default',
max_lines = 500,
},
priorities = {
clear = 198,
syntax = 199,
line_bg = 200,
char_bg = 201,
},
overrides = {},
},
conflict = {
enabled = true,
disable_diagnostics = true,
show_virtual_text = true,
show_actions = false,
keymaps = {
ours = 'doo',
theirs = 'dot',
both = 'dob',
none = 'don',
next = ']c',
prev = '[c',
},
},
}
<
*diffs.Config*
Fields: ~
{debug} (boolean, default: false)
Enable debug logging to |:messages| with
`[diffs]` prefix.
{hide_prefix} (boolean, default: false)
Hide diff prefixes (`+`/`-`/` `) using virtual
text overlay. Makes code appear without the
leading diff character. When `highlights.background`
is also enabled, the overlay inherits the line's
background color.
{fugitive} (boolean|table, default: false)
Enable vim-fugitive integration. Pass `true`
for defaults, `false` to disable, or a table
with sub-options (see |diffs.FugitiveConfig|).
Passing a table implicitly enables the
integration — no `enabled` field needed.
When active, the `fugitive` filetype is
registered and status buffer keymaps are set. >lua
vim.g.diffs = { fugitive = true }
vim.g.diffs = {
fugitive = { horizontal = 'dd' },
}
<
{neogit} (boolean|table, default: false)
Enable Neogit integration. Pass `true` or
`{}` to enable, `false` to disable. When
active, `NeogitStatus`, `NeogitCommitView`,
and `NeogitDiffView` filetypes are registered
and Neogit highlight overrides are applied.
See |diffs-neogit|. >lua
vim.g.diffs = { neogit = true }
<
{extra_filetypes} (table, default: {})
Additional filetypes to attach to, beyond the
built-in `git`, `gitcommit`, and any enabled
integration filetypes. Use this to enable
highlighting in plain `.diff` / `.patch`
files: >lua
vim.g.diffs = {
extra_filetypes = { 'diff' },
}
<
{highlights} (table, default: see below)
Controls which highlight features are enabled.
See |diffs.Highlights| for fields.
{conflict} (table, default: see below)
Inline merge conflict resolution options.
See |diffs.ConflictConfig| for fields.
*diffs.Highlights*
Highlights table fields: ~
{background} (boolean, default: true)
Apply background highlighting to `+`/`-` lines
using `DiffsAdd`/`DiffsDelete` groups (derived
from `DiffAdd`/`DiffDelete` backgrounds).
{gutter} (boolean, default: true)
Highlight line numbers with matching colors.
Only visible if line numbers are enabled.
{blend_alpha} (number, default: 0.6)
Alpha value for character-level blend intensity.
Controls how strongly changed characters stand
out from the line-level background. Must be
between 0 and 1 (inclusive). Higher values
produce more vivid character-level highlights.
{context} (table, default: see below)
Syntax parsing context options.
See |diffs.ContextConfig| for fields.
{treesitter} (table, default: see below)
Treesitter highlighting options.
See |diffs.TreesitterConfig| for fields.
{vim} (table, default: see below)
Vim syntax highlighting options (experimental).
See |diffs.VimConfig| for fields.
{intra} (table, default: see below)
Character-level (intra-line) diff highlighting.
See |diffs.IntraConfig| for fields.
{priorities} (table, default: see below)
Extmark priority values.
See |diffs.PrioritiesConfig| for fields.
{overrides} (table, default: {})
Map of highlight group names to highlight
definitions (see |nvim_set_hl()|). Applied
after all computed groups without `default`,
so overrides always win over both computed
defaults and colorscheme definitions.
*diffs.ContextConfig*
Context config fields: ~
{enabled} (boolean, default: true)
Read lines from disk before and after each hunk
to provide surrounding syntax context. Improves
accuracy at hunk boundaries where incomplete
constructs (e.g., a function definition with no
body) would otherwise confuse the parser.
{lines} (integer, default: 25)
Number of context lines to read in each
direction. Lines are read with early exit —
cost scales with this value, not file size.
*diffs.PrioritiesConfig*
Priorities config fields: ~
{clear} (integer, default: 198)
Priority for `DiffsClear` extmarks that reset
underlying diff foreground colors. Must be
below {syntax}.
{syntax} (integer, default: 199)
Priority for treesitter and vim syntax extmarks.
Must be below {line_bg} so that colorscheme
backgrounds on syntax groups do not obscure
line-level diff backgrounds.
{line_bg} (integer, default: 200)
Priority for `DiffsAdd`/`DiffsDelete` line
background extmarks. Must be below {char_bg}.
{char_bg} (integer, default: 201)
Priority for `DiffsAddText`/`DiffsDeleteText`
character-level background extmarks. Highest
priority so changed characters stand out.
*diffs.TreesitterConfig*
Treesitter config fields: ~
{enabled} (boolean, default: true)
Apply treesitter syntax highlighting to code.
{max_lines} (integer, default: 500)
Skip treesitter highlighting for hunks larger than
this many lines. Prevents lag on massive diffs.
*diffs.VimConfig*
Vim config fields: ~
{enabled} (boolean, default: false)
Use vim syntax highlighting as fallback when no
treesitter parser is available for a language.
Creates a scratch buffer, sets the filetype, and
queries |synID()| per character to extract
highlight groups. Slower than treesitter but
covers languages without a TS parser installed.
{max_lines} (integer, default: 200)
Skip vim syntax highlighting for hunks larger than
this many lines. Lower than the treesitter default
due to the per-character cost of |synID()|.
*diffs.IntraConfig*
Intra config fields: ~
{enabled} (boolean, default: true)
Enable character-level diff highlighting within
changed lines. When a line changes from `local x = 1`
to `local x = 2`, only the `1`/`2` characters get
an intense background overlay while the rest of the
line keeps the softer line-level background.
{algorithm} (string, default: 'default')
Diff algorithm for character-level analysis.
`'default'`: use |vim.diff()| with settings
inherited from |'diffopt'| (`algorithm` and
`linematch`). `'vscode'`: use libvscodediff FFI
(falls back to default if not available).
{max_lines} (integer, default: 500)
Skip character-level highlighting for hunks larger
than this many lines.
Note: Header context (e.g., `@@ -10,3 +10,4 @@ func()`) is always
highlighted with treesitter when a parser is available.
Language detection uses Neovim's built-in |vim.filetype.match()| and
|vim.treesitter.language.get_lang()|. To customize filetype detection
or register treesitter parsers for custom filetypes, use
|vim.filetype.add()| and |vim.treesitter.language.register()|.
==============================================================================
COMMANDS *diffs-commands*
:Gdiff [revision] *:Gdiff*
Open a unified diff of the current file against a git revision. Displays
in a horizontal split below the current window.
The diff buffer shows `+`/`-` lines with full syntax highlighting for the
code language, plus diff header highlighting for `diff --git`, `---`,
`+++`, and `@@` lines.
If a `diffs://` window already exists in the current tabpage, the new
diff replaces its buffer instead of creating another split.
Parameters: ~
{revision} (string, optional) Git revision to diff against.
Defaults to HEAD.
Examples: >vim
:Gdiff " diff against HEAD
:Gdiff main " diff against main branch
:Gdiff HEAD~3 " diff against 3 commits ago
:Gdiff abc123 " diff against specific commit
<
:Gvdiff [revision] *:Gvdiff*
Like |:Gdiff| but opens in a vertical split.
:Ghdiff [revision] *:Ghdiff*
Like |:Gdiff| but explicitly opens in a horizontal split.
==============================================================================

Jump to next unresolved conflict hunk in merge diff.
*<Plug>(diffs-merge-prev)*
<Plug>(diffs-merge-prev)
Jump to previous unresolved conflict hunk in merge
diff.
Diff buffer mappings: ~
*diffs-q*
q Close the diff window. Available in all `diffs://`
buffers created by |:Gdiff|, |:Gvdiff|, |:Ghdiff|,
or the fugitive status keymaps.
==============================================================================
FUGITIVE STATUS KEYMAPS *diffs-fugitive*
When inside a vim-fugitive |:Git| status buffer, diffs.nvim provides keymaps
to open unified diffs for files or entire sections.
Keymaps: ~
*diffs-du* *diffs-dU*
du Open unified diff in a horizontal split.
dU Open unified diff in a vertical split.
These keymaps work on:
- File lines (e.g., `M src/foo.lua`) - opens diff for that file
- Section headers (e.g., `Staged (3)`) - opens diff for all files in section
- Hunk/context lines below a file - opens diff for the parent file
Behavior by file status: ~
Status Section Base Current Result ~
M Unstaged index working tree unstaged changes
M Staged HEAD index staged changes
A Staged (empty) index file as all-added
D Staged HEAD (empty) file as all-removed
R Staged HEAD:oldname index:newname content diff
U Unstaged :2: (ours) :3: (theirs) merge diff
? Untracked (empty) working tree file as all-added
On section headers, the keymap runs `git diff` (or `git diff --cached` for
staged) and displays all changes in that section as a single unified diff.
Untracked section headers show a warning since there is no meaningful diff.
Configuration: ~
*diffs.FugitiveConfig*
>lua
vim.g.diffs = {
fugitive = {
horizontal = 'du', -- keymap for horizontal split, false to disable
vertical = 'dU', -- keymap for vertical split, false to disable
},
}
<
Passing a table enables fugitive integration. Use `fugitive = false`
to disable. There is no `enabled` field; table presence is sufficient.
Fields: ~
{horizontal} (string|false, default: 'du')
Keymap for unified diff in horizontal split.
Set to `false` to disable.
{vertical} (string|false, default: 'dU')
Keymap for unified diff in vertical split.
Set to `false` to disable.
==============================================================================
CONFLICT RESOLUTION *diffs-conflict*
diffs.nvim detects inline merge conflict markers (`<<<<<<<`/`=======`/
`>>>>>>>`) in working files and provides highlighting and resolution keymaps.
Both standard and diff3 (`|||||||`) formats are supported.
Conflict regions are detected automatically on `BufReadPost` and re-scanned
on `TextChanged`. When all conflicts in a buffer are resolved, highlighting
is removed and diagnostics are re-enabled.
Configuration: ~
*diffs.ConflictConfig*
>lua
vim.g.diffs = {
conflict = {
enabled = true,
disable_diagnostics = true,
show_virtual_text = true,
show_actions = false,
priority = 200,
keymaps = {
ours = 'doo',
theirs = 'dot',
both = 'dob',
none = 'don',
next = ']c',
prev = '[c',
},
},
}
<
Fields: ~
{enabled} (boolean, default: true)
Enable conflict marker detection and
resolution. Set to `false` to disable
entirely.
{disable_diagnostics} (boolean, default: true)
Suppress LSP diagnostics on buffers with
conflict markers. Markers produce syntax
errors that clutter the diagnostic list.
Diagnostics are re-enabled when all conflicts
are resolved. Set `false` to leave
diagnostics alone.
{show_virtual_text} (boolean, default: true)
Show `(current)` and `(incoming)` labels at
the end of `<<<<<<<` and `>>>>>>>` marker
lines. Also controls hunk hints in merge
diff views.
{format_virtual_text} (function|nil, default: nil)
Custom formatter for virtual text labels.
Receives `(side, keymap)` where `side` is
`"ours"` or `"theirs"` and `keymap` is the
configured keymap string or `false`. Return
a string (label text without parens) or
`nil` to hide the label. Example: >lua
format_virtual_text = function(side, keymap)
if keymap then
return side .. ' [' .. keymap .. ']'
end
return side
end
<
{show_actions} (boolean, default: false)
Show a codelens-style action line above each
`<<<<<<<` marker listing available resolution
keymaps. Renders as virtual lines using the
`DiffsConflictActions` highlight group.
Only keymaps that are not `false` appear.
{priority} (integer, default: 200)
Extmark priority for conflict region
backgrounds and markers. Adjust if other
plugins use the same priority range.
{keymaps} (table, default: see above)
Buffer-local keymaps for conflict resolution
and navigation. Each value accepts a string
(custom key) or `false` (disabled).
*diffs.ConflictKeymaps*
Keymap fields: ~
{ours} (string|false, default: 'doo')
Accept current (ours) change.
{theirs} (string|false, default: 'dot')
Accept incoming (theirs) change.
{both} (string|false, default: 'dob')
Accept both changes (ours then theirs).
{none} (string|false, default: 'don')
Reject both changes (delete entire block).
{next} (string|false, default: ']c')
Jump to next conflict marker. Wraps around.
{prev} (string|false, default: '[c')
Jump to previous conflict marker. Wraps
around.
User events: ~
*DiffsConflictResolved*
DiffsConflictResolved Fired when the last conflict in a buffer is
resolved. Useful for triggering custom actions
(e.g., auto-staging the file). >lua
vim.api.nvim_create_autocmd('User', {
pattern = 'DiffsConflictResolved',
callback = function()
print('all conflicts resolved!')
end,
})
<
==============================================================================
MERGE DIFF RESOLUTION *diffs-merge*
When pressing `du`/`dU` on an unmerged (`U`) file in the fugitive status
buffer, diffs.nvim opens a unified diff of ours (`git show :2:path`) vs
theirs (`git show :3:path`) with full treesitter and intra-line highlighting.
The same conflict resolution keymaps (`doo`/`dot`/`dob`/`don`/`]c`/`[c`)
are available on the diff buffer. They resolve conflicts in the working
file by matching diff hunks to conflict markers:
- `doo` replaces the conflict region with ours content
- `dot` replaces the conflict region with theirs content
- `dob` replaces with both (ours then theirs)
- `don` removes the conflict region entirely
- `]c`/`[c` navigate between unresolved conflict hunks
Resolved hunks are marked with `(resolved)` virtual text. Hunks that
correspond to auto-merged content (no conflict markers) show an
informational notification and are left unchanged.
The working file buffer is modified in place; save it when ready.
Phase 1 inline conflict highlights (see |diffs-conflict|) are refreshed
automatically after each resolution.
==============================================================================
NEOGIT *diffs-neogit*
diffs.nvim works with Neogit (https://github.com/NeogitOrg/neogit) out of
the box. Enable Neogit support in your config: >lua
vim.g.diffs = { neogit = true }
<
When a diff is expanded in a Neogit buffer (e.g., via TAB on a file in the
status view), diffs.nvim applies treesitter syntax highlighting and
intra-line diffs to the hunk lines, just as it does for fugitive.
Neogit highlight overrides: ~
On first attach to a Neogit buffer, diffs.nvim overrides Neogit's diff
highlight groups (`NeogitDiffAdd*`, `NeogitDiffDelete*`,
`NeogitDiffContext*`, `NeogitHunkHeader*`, `NeogitDiffHeader*`, etc.) by
setting them to empty (`{}`). This gives diffs.nvim sole control of diff
line visuals. The overrides are reapplied on `ColorScheme` since Neogit
re-defines its groups then. When `neogit = false`, no highlight overrides
are applied.
==============================================================================
API *diffs-api*
attach({bufnr}) *diffs.attach()*
Manually attach highlighting to a buffer. Called automatically for
fugitive buffers via the `FileType fugitive` autocmd.
Parameters: ~
{bufnr} (integer, optional) Buffer number. Defaults to current buffer.
refresh({bufnr}) *diffs.refresh()*
Manually refresh highlighting for a buffer. Useful after external changes
or for debugging.
Parameters: ~
{bufnr} (integer, optional) Buffer number. Defaults to current buffer.
==============================================================================
IMPLEMENTATION *diffs-implementation*
Summary / commit detail views: ~
1. `FileType` autocmd for computed filetypes (see |diffs-config|) triggers
|diffs.attach()|. For `git` buffers, only `fugitive://` URIs are attached.
2. The buffer is parsed to detect file headers (`M path/to/file`,
`diff --git a/... b/...`) and hunk headers (`@@ -10,3 +10,4 @@`)
3. For each hunk:
- Language is detected from the filename using |vim.filetype.match()|
- Diff prefixes (`+`/`-`/` `) are stripped from code lines
- Code is parsed with |vim.treesitter.get_string_parser()|
- If no treesitter parser and `vim.enabled`: vim syntax fallback via
scratch buffer and |synID()|
- `DiffsClear` extmarks at priority 198 clear underlying diff foreground
- Syntax highlights are applied as extmarks at priority 199
- Background extmarks (`DiffsAdd`/`DiffsDelete`) at priority 200
- Character-level diff extmarks (`DiffsAddText`/`DiffsDeleteText`) at
priority 201 overlay changed characters with an intense background
- Conceal extmarks hide diff prefixes when `hide_prefix` is enabled
- All priorities are configurable via |diffs.PrioritiesConfig|
4. A decoration provider re-highlights visible hunks on each redraw
Diff mode views: ~
1. `OptionSet diff` detects when any window enters diff mode
2. All `&diff` windows in the tabpage receive a window-local 'winhighlight'
override that remaps `DiffAdd`/`DiffDelete`/`DiffChange`/`DiffText` to
background-only variants, allowing existing treesitter highlighting to
show through the diff colors
==============================================================================
KNOWN LIMITATIONS *diffs-limitations*
Incomplete Syntax Context ~
*diffs-syntax-context*
Treesitter parses each diff hunk in isolation. Context lines within the hunk
(lines with a ` ` prefix) provide syntactic context for the parser. In rare
cases, hunks that start or end mid-expression may produce imperfect highlights
due to treesitter error recovery.
Syntax Highlighting Flash ~
*diffs-flash*
When opening a fugitive buffer, there is an unavoidable visual "flash" where
the buffer briefly shows fugitive's default diff highlighting before
diffs.nvim applies treesitter highlights.
This occurs because diffs.nvim hooks into the `FileType fugitive` event,
which fires after vim-fugitive has already painted the buffer. The
decoration provider applies highlights on the next redraw cycle.
Conflicting Diff Plugins ~
*diffs-plugin-conflicts*
diffs.nvim may not interact well with other plugins that modify diff
highlighting or the sign column in diff views. Known plugins that may
conflict:
- diffview.nvim (sindrets/diffview.nvim)
Provides its own diff highlighting and conflict resolution UI.
When using diffview.nvim for viewing diffs, you may want to disable
diffs.nvim's diff mode attachment or use one plugin exclusively.
- mini.diff (echasnovski/mini.diff)
Visualizes buffer differences with its own highlighting system.
May override or conflict with diffs.nvim's background highlighting.
- gitsigns.nvim (lewis6991/gitsigns.nvim)
Generally compatible for sign column decorations, but both plugins
modifying line highlights may produce unexpected results.
- git-conflict.nvim (akinsho/git-conflict.nvim)
Provides conflict marker highlighting and resolution keymaps.
diffs.nvim now has built-in conflict resolution (see
|diffs-conflict|). Disable one or the other to avoid overlap.
If you experience visual conflicts, try disabling the conflicting plugin's
diff-related features.
==============================================================================
HIGHLIGHT GROUPS *diffs-highlights*
diffs.nvim defines custom highlight groups. All groups use `default = true`,
so colorschemes can override them by defining the group before the plugin
loads.
All derived groups are computed by alpha-blending a source color into the
`Normal` background. Line-level groups blend at 40% alpha for a subtle tint;
character-level groups blend at 60% for more contrast. Line-number groups
combine both: background from the line-level blend, foreground from the
character-level blend.
Fugitive unified diff highlights: ~
*DiffsAdd*
DiffsAdd Background for `+` lines. Derived by blending
`DiffAdd` background with `Normal` at 40% alpha.
*DiffsDelete*
DiffsDelete Background for `-` lines. Derived by blending
`DiffDelete` background with `Normal` at 40% alpha.
*DiffsAddNr*
DiffsAddNr Line number for `+` lines. Foreground from
`DiffsAddText`, background from `DiffsAdd`.
*DiffsDeleteNr*
DiffsDeleteNr Line number for `-` lines. Foreground from
`DiffsDeleteText`, background from `DiffsDelete`.
*DiffsAddText*
DiffsAddText Character-level background for changed characters
within `+` lines. Derived by blending `diffAdded`
foreground with `Normal` background at 60% alpha.
Only sets `bg`, so treesitter foreground colors show
through.
*DiffsDeleteText*
DiffsDeleteText Character-level background for changed characters
within `-` lines. Derived by blending `diffRemoved`
foreground with `Normal` background at 60% alpha.
Conflict highlights: ~
*DiffsConflictOurs*
DiffsConflictOurs Background for "ours" (current) content lines.
Derived by blending `DiffAdd` background with
`Normal` at 40% alpha (green tint).
*DiffsConflictTheirs*
DiffsConflictTheirs Background for "theirs" (incoming) content lines.
Derived by blending `DiffChange` background with
`Normal` at 40% alpha.
*DiffsConflictBase*
DiffsConflictBase Background for base (ancestor) content lines in
diff3 conflicts. Derived by blending `DiffText`
background with `Normal` at 30% alpha (muted).
*DiffsConflictMarker*
DiffsConflictMarker Dimmed foreground with bold for `<<<<<<<`,
`=======`, `>>>>>>>`, and `|||||||` marker lines.
*DiffsConflictOursNr*
DiffsConflictOursNr Line number for "ours" content lines. Foreground
from higher-alpha blend, background from line-level
blend.
*DiffsConflictTheirsNr*
DiffsConflictTheirsNr Line number for "theirs" content lines.
*DiffsConflictBaseNr*
DiffsConflictBaseNr Line number for base content lines (diff3).
*DiffsConflictActions*
DiffsConflictActions Dimmed foreground (no bold) for the codelens-style
action line shown when `show_actions` is true.
Diff mode window highlights: ~
These are used for |winhighlight| remapping in `&diff` windows.
*DiffsDiffAdd*
DiffsDiffAdd Background-only. Derived from `DiffAdd` bg.
Treesitter provides foreground syntax highlighting.
*DiffsDiffDelete*
DiffsDiffDelete Foreground and background from `DiffDelete`.
Used for filler lines (`/////`) which have no real
code content to highlight.
*DiffsDiffChange*
DiffsDiffChange Background-only. Derived from `DiffChange` bg.
Treesitter provides foreground syntax highlighting.
*DiffsDiffText*
DiffsDiffText Background-only. Derived from `DiffText` bg.
Treesitter provides foreground syntax highlighting.

vim.api.nvim_set_hl(0, 'DiffsAdd', { bg = '#2e4a3a' })
vim.api.nvim_set_hl(0, 'DiffsDiffDelete', { link = 'DiffDelete' })
<
Or via `highlights.overrides` in config: >lua
vim.g.diffs = {
highlights = {
overrides = {
DiffsAdd = { bg = '#2e4a3a' },
DiffsDiffDelete = { link = 'DiffDelete' },
},
},
}
