When a rebase (or multi-commit cherry-pick or revert) stops with a
conflict, it is often useful to look at the diff of the "<-- CONFLICT"
commit to double-check that the conflict resolution matches the diff of
the original commit. To make that easier, select that commit
automatically.
This doesn't change anything, we just pin down the selection behavior
around conflicts; we are going to change that behavior, and these tests
will make it obvious how when they change in the next commit.
I'm not a skilled UI designer, so I suspect there may be even better
options, but it's definitely already better than the raw ASCII "---" we
had before.
Put the line only at the beginning because it looks bad if the line
after the label is misaligned when labels don't have the same width
(e.g. "Remote" vs. "Local" in the divergence view).
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).
