The pane beside a commit's diff showed the patch being built from it by
assembling the text itself. That text could not be handed to a diff
renderer the way a diff can: a stdin filter might have coped, but a tool
that diffs two files could not. Its idea of how much context to show
around a hunk was also its own rather than git's.
Materialize the patch instead: write each of its files as it is before the
patch into one tree and as it is after into another, and let git diff the
two trees. The patch becomes a diff of real files, rendered by whatever
renders the rest of them, with git's own context around it. Its lines can
then be pointed at; taking them back out of the patch will need that.
The trees are named a and b, so that with git's own prefixes suppressed
the paths read like an ordinary diff's over the repo's own paths. They are
written when the patch changes rather than when it is shown, the patch
builder counting its own versions for that, and they go away with the
patch.
A renamed file is materialized under the name the patch expects to find it
under. Where the patch carries the rename, that is the name the file had
before, so the rename comes out as a rename. git names the trees
themselves in the two rename lines, having only the two paths to go by.

Two things about a diff command follow from what its output is for: whether
the diff renderer produces it, and whether it is coloured. That was a
`plain` flag, which covers two of the three cases — the diff as configured,
and git's own uncoloured diff for building patches out of — and leaves no
room for the third, which is about to be needed: git's own diff, coloured,
for showing where the renderer's version of it can't be acted on.
So the flag becomes a mode. It also takes over deciding the colour, which
each command spelled out for itself, and it settles a question the flag
couldn't put: whether ignoring whitespace applies. It is about what the user
wants to see, so it holds for anything shown, and not for a diff a patch is
built from, which has to describe every change.

The detailed commit graph is only drawn for users who set
gui.commitGraphStyle to 'detailed'. Many users of terminals that can
draw it will never find out about it. A terminal can't be asked whether
it draws a given character, but it does tell us its name and version
when tcell asks for them with XTVERSION at startup.
Add an 'auto' value and make it the default. It uses the detailed graph
in kitty from 0.36.2 and in Ghostty from 1.0.0 on. These are the first
versions that draw all of the symbols. Everywhere else it stays with
the classic graph. This includes tmux, because tmux answers XTVERSION
itself. So far, WezTerm draws the symbols only in its nightly builds, so
it isn't detected until a release has them. VS Code isn't detected
either, because it only draws the symbols with GPU acceleration.
The expected output of the integration tests has the classic graph, so
pin it in their config. Otherwise they would fail when run with a
visible UI in one of these terminals.
Log the terminal's name and version at startup, to make it possible to
find out why 'auto' picked what it did.

If a branch forks off a merge commit, the graph can't show both lines
in the merge commit's row. The line from the branch's first commit ends
in the same cell in which the merge's line to its second parent starts.
The box drawing characters have no symbol for a line from above that
bends to the left combined with a line from the left that bends down,
so one of the two gets lost. Today the cell shows a plain vertical
line, and the branch looks as if it sat on the merge's second parent
(#5497).
The branch drawing symbols in the Unicode Private Use Area (U+F5D0 to
U+F60D) have a symbol for every way in which lines meet in a cell.
kitty introduced them for git graph viewers like vim-flog, and Ghostty,
Contour, the terminal of VS Code and nightly builds of WezTerm render
them too. Other terminals need a font that contains them.
Add the gui.commitGraphStyle config. Its 'detailed' style draws the
graph with these symbols, and the commit symbols of the set connect to
their lines. Commits are drawn as hollow circles and merge commits as
filled ones. The default stays the 'classic' style with the box drawing
characters, because not every terminal can display the others.
A cell has only one colour. Where two lines meet, the symbol takes the
colour of the line from above. With the box drawing characters,
highlighting the lines of the selected commit clears the cells they run
through. The branch drawing symbols keep the other lines. A cell in
which a highlighted line bends is highlighted as a whole. Where a
highlighted line crosses the vertical line of another commit, it is
drawn over that line, so that it reads as one line. In a cell in which
another line bends, the symbol keeps the colour of that line.

This separates choosing the characters from writing them out with their
styles, so that the next commit can add another set of characters.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
A cell of the commit graph only records which of its edges are touched
by lines. That's all the box drawing characters can show, but it
doesn't say how the lines connect. A vertical line with a horizontal
line passing behind it touches all four edges. So does a cell in which
the line from above bends to the left, the line below comes in from the
left, and a horizontal line passes through.
For the lines at the top and bottom edges, record whether they run
straight on or bend to the left or right, and record whether a line
passes through horizontally. Nothing reads this yet. It prepares for
drawing the graph with symbols that can show these differences.

If a root commit isn't the last one in the list, the graph draws a
vertical line below it in every row that follows. A root commit's pipe
to the empty tree never terminates, because no commit comes after it,
so it is carried on from row to row. The line also takes up its column,
and an unrelated commit after the root commit is placed to the right of
it.
Drop that pipe after the root commit's row. In its own row, it still
gives the commit symbol the style of the commit. Also, place a commit
that no line leads to next to the lines that go on into its row, not
next to the lines that ended in the row before. Their columns are free
again.

If a root commit isn't the last one in the list, the graph draws a
vertical line below it in every row that follows, although nothing
comes after a root commit. This happens in repos with more than one
root commit, for example when showing all branches of a repo with a
gh-pages branch, or after merging an unrelated history.
Also, a commit that no line leads to is placed to the right of the
lines that ended in the row before it, although their columns are free
again.

When somebody else rebases a branch and force-pushes it, our branch
shows up as diverged, say ↓5↑3, and that looks exactly like a branch
that carries three commits of our own. The two want different treatment.
The first one only has to be moved to its upstream, while the second one
needs a decision about what to do with those commits. The panel doesn't
tell them apart, so users have to look at each branch in turn to find
out which one they are dealing with.
Determine for every diverged branch whether it has commits of its own,
and dim its divergence when it doesn't. This runs on a worker, as it
takes a few git commands per diverged branch, and a branch keeps the
answer from the previous load while a new one is in flight, so that the
display doesn't flicker. A later commit teaches the fast-forward command
to act on such a branch.

While bisecting, the hashes of the commits outside the bisect range are
black. On a dark gray background this makes them recede, but on a black
one they are invisible, and on a light one they stand out more than any
other hash.
Draw them in faint text instead. The terminal shades faint text toward
its background, whatever that is.

We are about to add overrides of gui.theme for dark and light
backgrounds. Author and branch colors need them too, because a color
that reads well on a dark background may be hard to read on a light
one. Move them into gui.theme, so that the overrides cover them without
a mechanism of their own.
The migration of gui.branchColors creates gui.branchColorPatterns, so it
now has to run before the moves.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
If several patterns in gui.branchColorPatterns match a branch, the color
it gets is picked at random, and it can change from one render to the
next. The patterns are kept in a Go map, and Go randomizes the order in
which a map is iterated.
Keep the patterns in a list instead, in the order in which they are
written, and let the first match win. If a repo's config file has
patterns too, put them in front of those of the global config file,
because they are more specific.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
gui.branchColors has been deprecated in favor of gui.branchColorPatterns
since 0.44.0. We are about to move gui.branchColorPatterns into
gui.theme, and the deprecated key would have to move along with it.
Migrate it instead, so that we can remove it.
gui.branchColors matched its keys against the part of a branch name
before the first slash. The pattern ^<key>(/|$), with the key escaped,
matches the same branches.
If gui.branchColorPatterns is set, gui.branchColors has no effect; in
that case the migration removes it. This check is done per file. So if
the global config sets gui.branchColorPatterns and a repo config sets
only gui.branchColors, the repo's colors were ignored so far, and now
they apply.

The colors that lazygit derives from the names of authors are picked
for a dark background. On a light one, they are too pale to read;
against white, every author has a contrast ratio between 2.2:1 and
3.5:1.
Now that lazygit knows whether the terminal is dark or light, pick them
from a darker range of lightness when it is light. Against white, the
contrast ratio is now between 5.2:1 and 9.2:1, and against the
background of Solarized Light between 4.8:1 and 8.5:1. On a dark
background, nothing changes. If the terminal switches between dark and
light while lazygit is running, draw the commits again in the new
colors.
Add gui.colorScheme for terminals that don't tell us, and for anyone
who wants to override what they tell. It is 'auto' by default; 'dark'
and 'light' ignore what the terminal says.

If gui.authorColors names no color for an author, lazygit picks one
from a hash of their name, at an HSL lightness between 0.4 and 0.6.
HSL lightness says nothing about how bright a color looks, though. At
0.5 a yellow is glaring and a blue is nearly black, so whether an
author's initials can be read comes down to where their name happens
to hash to. Against a background of #1e1e1e, 45% of four thousand
names fall below a contrast ratio of 4.5:1 and 21% below 3:1, with the
worst at 1.46:1. Several issues have been raised about author colors
being too dark to read.
Use HSLuv instead. Its lightness tracks perceived brightness, so the
range can be narrow now that a number in it means something. Against
#1e1e1e, every author now lands between 4.7:1 and 7.7:1, so no name is
unlucky any more.
This changes the color of every author who isn't named in
gui.authorColors. On a light background, the new colors are uniformly
too pale, where before they were mostly too pale. The next commit gives
a light background a range of its own.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
If gui.authorColors names no color for an author, lazygit derives one
from a hash of their name. Checking whether these colors are readable
means looking at a repository, but the authors of a real one rarely
land near the edges of the range, so the worst cases go unseen.
Add cmd/author_colors_repo. It searches for names at the lowest and
highest lightness and saturation, at twelve hues, and commits once as
each of them. The names depend only on the hashing, so the same
repository shows the colors of any lazygit build and can be kept
around to compare them.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
The next commit adds a tool that creates a repository of authors at
the edges of the range their colors are picked from. To find such
names, it needs to know where a name lands in the range, and it
shouldn't keep a copy of the hashing that could drift from this one.
Later commits test the colors, and need the colors themselves for that
rather than the styles made from them.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
When the config is reloaded, SetCustomAuthors replaces the styles of
authors, but the initials and names that were rendered with the old
styles stay cached. So do the pipes of the commit graph; each of them
carries the style of the author of the commit it starts at.
Drop these whenever the colors of authors change. The graph's cache
finds out by itself, by comparing a version number, so that nothing
has to remember to reset it.

If gui.authorColors changes while lazygit is running, the authors that

The styles from gui.authorColors and the ones derived from the names
of the other authors share a map, so the derived ones can't be dropped
without the configured ones. A later commit needs to drop the derived
ones on their own, when the terminal switches between dark and light.

Pad the date of every line to the width that the oldest entry in the
reflog asks for, so that the column keeps its width as the user scrolls.
This is the same treatment the commits panel's date column gets, with the
same limits; getReservedColumnWidths spells them out.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The reflog panel renders only the lines that are on screen too, so the
expanded panel's date column is only as wide as gui.shortTimeFormat while
nothing but entries from today is visible, and the message of every entry
jumps to the left. A reflog reaches back in time, so scrolling crosses
that boundary soon enough.
GetReflogCommitListDisplayStrings had no tests at all, so cover the two
shapes it can return along the way.
This file is deliberately left un-gofumpt'd: gofumpt indents the body of
the commented-out block by a tab, which would fill the diff of the commit
that swaps the two blocks with whitespace-only changes.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The reflog commits context slices the visible lines out itself and passes
only those, so the function has no way to look at the rest of the list. A
following commit needs the oldest entry to work out how much width the
date column needs. Take the whole list along with the range to render, the
way GetCommitListDisplayStrings already does.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
During an interactive rebase, scrolling down far enough that the pending
todos leave the screen makes the author and subject of every commit jump
to the left; scrolling back up makes them jump back. During a bisect the
column that holds "<-- current" and "?" comes and goes the same way, and
in the expanded commits panel the date column is only as wide as
gui.shortTimeFormat while nothing but today's commits is on screen.
A column is as wide as the widest string in it, and a column whose strings
are all empty is dropped altogether. The commits and sub-commits panels
render only the lines that are on screen, so those widths come from the
visible lines alone and follow the scroll position.
Pad the hash, bisect, action and date cell of every line to the width that
all the commits in the list need. A padded cell is no longer empty, so its
column is never dropped, and the column is already as wide as the whole
list needs, so its width no longer depends on what is visible.
The date column is the exception. Formatting the date of every commit on
every render costs too much, so it measures the oldest commit only. That
covers the conventional time formats; getReservedColumnWidths says what it
misses, and why it can never reserve width that no commit asks for.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The commits panel renders only the lines that are on screen, so the width
of a column follows what happens to be visible, and a column all of whose
visible lines are empty disappears altogether. Scrolling past the pending
rebase todos takes the action column away with them, and everything to its
right jumps to the left.
Cover the same problem for two more columns: the hash column, which goes
away while only hashless todos such as "update-ref" are on screen, and the
date column in the expanded commits panel, which is as narrow as the time
format while only commits from today are on screen.
This file is deliberately left un-gofumpt'd: gofumpt indents the body of
the commented-out block by a tab, which would fill the diff of the commit
that swaps the two blocks with whitespace-only changes.

formatExpected runs the expected output through strings.TrimSpace to get
rid of the newlines that the raw string literal starts and ends with, but
that also eats the indentation of the first line. A scenario whose first
line starts with an empty column can't express what it expects, and a
later commit adds two of those. Trim the newlines only.

These three cells are built and styled in one step, so their width can
only be measured by stripping the styling off again. A later commit needs
those widths to reserve space for the columns they go into. Pull the text
out into getHashText, getActionText and a getBisectStatusText that no
longer styles what it returns, and apply the styling at the call site.
A commit with no hash, such as a "break" or "update-ref" todo, now gets an
empty hash cell instead of one holding nothing but colour codes. Nothing
can see the difference: both render as the same number of blank columns.

The recent repos menu is about to show the same text for a repo that has
no branch checked out. Hardcoding the English a second time would leave

In the branches list we show the checks icon (✓, ✗ etc) instead of the
gihub icon for branches that are open and have a state. It is a little
confusing, because the ✓ in front of the name means something very
different than the ✓ after it, but the checks status is just too useful
to see in the list.
In the main view we show it as a compact status before the PR title,
with a hyperlink that takes you directly to the checks tab in Github.
The branch controller should decide which pull request to show, not how its
header is styled and linked. Move the existing formatter and state badge next
to the branch presentation helpers so subsequent header changes stay in one
layer.
When loading the files of a commit we passed --no-renames, so a rename
showed up as a separate delete and add rather than a single R entry.
That made it impossible to work with a rename that also modifies the
file: the modifications were spread across a full deletion and a full
addition instead of appearing as the handful of lines that actually
changed. The staging view already shows renames and lets you stage
their hunks, so there was no good reason for the patch builder to
differ; the flag was only there because the commit-file parser couldn't
cope with the rename record format.
Switch the commit-file loader and the per-file diff to --find-renames,
teach the parser about the rename record (a status followed by two
paths), and carry the previous path through the patch builder so the
diff for a rename is loaded with both paths, which is what makes git
emit the rename in the first place.
A whole-file selection keeps the rename in the header, so the rename
moves or is discarded together with the file's contents. A partial
selection instead strips the rename metadata and points the header at
the new path, so applying the patch only changes the contents and
leaves the rename in place; the blob index line is kept so that a 3-way
apply can still fall back to a blob merge.
Discarding a renamed file from a commit now discards both the new and
the old path, so the new file is removed and the old one is restored.
Changing the rename similarity threshold refreshes the commit files
panel too, not just the files panel, so that a rename can turn into a
delete and add or back. It is disabled while building a patch, however,
because the patch builder caches each file's diff by path and would
desync if a rename changed into a delete and add underneath it.
Finally, copying a file's diff from the commit files panel now passes
both paths for a rename, so the copied diff shows the rename instead of
a new-file add.

The commit graph used '⏣' (U+23E3 BENZENE RING WITH CIRCLE) for merge
commits and '◯' (U+25EF LARGE CIRCLE) for regular commits. Both have
very poor coverage in popular monospace fonts:
- '⏣' lives in the Misc Technical block and is essentially absent from
every common monospace font (Source Code Pro, JetBrains Mono, Fira
Code, Cascadia Code, Hack, Iosevka, Menlo, Consolas, Monaco, IBM
Plex Mono, Ubuntu Mono, Noto Sans Mono, Inconsolata). It is always
drawn from a system fallback font.
- '◯' is the late-addition LARGE CIRCLE codepoint. It is present in
some fonts (Cascadia, Fira Code, Hack, Iosevka, Menlo, Noto Sans
Mono) but missing from many others, including Source Code Pro and
most Nerd Font derivatives based on it.
This is why the graph renders inconsistently across platforms even
when the same monospace font is configured: each OS picks a different
fallback font (Apple Symbols on macOS, Segoe UI Symbol on Windows,
Noto/DejaVu/Symbola on Linux), and the substituted glyphs differ in
shape, weight, and advance width. '◯' is also East Asian Ambiguous
width, so some terminals render it wider than one cell, exaggerating
the misalignment.
Replace the symbols with codepoints from the foundational 1991
Geometric Shapes block, which has far broader font coverage:
- Merge: '◎' U+25CE BULLSEYE -- concentric circles, the visually
closest cousin to the previous benzene-ring glyph.
- Commit: '○' U+25CB WHITE CIRCLE -- the same hollow-circle silhouette
as before, just a more universally available codepoint.
The new symbols are present in the font directly in significantly
more cases; and when fallback is still required, they are universally
well-drawn (unlike '⏣', which many fallback fonts also lack).

The call was meant to guarantee a UTC time zone to make the tests deterministic,
but as the previous commit explained, this only worked on Mac and Linux, not on
Windows. Since we now have a better fix, this workaround is no longer needed.
This is so that they look the same no matter what color palette the terminal is
using. (One user complained that the text for the Open state is barely readable,
because they are using a palette that has a very pale green.)
GitHub uses slightly different colors depending on light vs. dark mode;
fortunately they are very close, so hopefully we can ignore this. I picked the
ones for dark mode here, on the assumption that this is more common.
Also, not all terminals support true hex colors; for example, Terminal.app on
macOS doesn't, so it maps the colors to the closest ones in the Xterm-256
palette. This shouldn't be a huge problem, but for some reason it displays draft
PRs as something closer to Cyan than grey, and I don't understand why.
The assumption is that if a pull request exists on a main branch, it was usually
created by mistake and then closed, and showing it serves no purpose and is only
distracting.
We keep showing open pull requests for main branches though, because this allows
you to notice that there is one that you probably want to close.
This only affects the display (in the branches list and in the main view);
opening the PR in the browser using shift-G is still possible, as is copying its
URL to the clipboard.
The only information that this carries is whether an entry is a real branch or a
detached head. Detached heads can only be at the top, and they are easy to tell
apart from the other branches by their name, so the icon is not really very
useful.
We are going to show PR icons in this column.
If the showDivergenceFromBaseBranch config is not none, the expanded branches
panel would no longer show the remote branch and subject; the reason was that we
padded the name all the way to the right edge of the view so that the divergence
information is right-aligned.
To fix this, we simply don't right-align the divergence in half or full screen
mode. This is a bit unfortunate, but it's hard to do any better, because we
don't know the width of our column in advance. One thing I tried is to make the
divergence a separate column in that case (with an explicit right-alignment set
on it via getColumnAlignments; however, this makes it harder to properly
truncate the name when the window is too narrow.
When a branch is checked out by another worktree, show the worktree
name in the label, e.g. "(worktree cosmos2)" instead of just
"(worktree)", so you can immediately see which worktree holds it.
The worktrees tab now displays the checked-out branch (or detached HEAD
state) for each worktree, making it much easier to see which worktree
holds which branch.
This is useful when you need to "unlock" a branch that's occupied by
another worktree: you can now clearly see which worktrees are on a
branch vs detached, without having to select each one individually.
Also rename the "(main)" label to "(main worktree)" to avoid confusion
with the common "main" branch name, and move it after the branch column.
When replacing the naked return with a `return result`, the linter starts to
complain about "return copies lock value: sync/atomic.Int32 contains
sync/atomic.noCopy". I suspect this is also a problem when using a naked return,
and the linter just doesn't catch it in that case. Either way, it's better to
use a pointer to ensure that the atomic is not copied.

I took the set of enabled checks from revive's recommended configuration [1],
and removed some that I didn't like. There might be other useful checks in
revive that we might want to enable, but this is a nice improvement already.
The bulk of the changes here are removing unnecessary else statements after
returns, but there are a few others too.
