The +list-themes interactive preview dropped the second emoji of ZWJ
clusters (e.g. woman + ZWJ + rocket) in the search box. Zig's libvaxis
enables Unicode grapheme mode 2027 for its session and sizes text per
grapheme cluster; the Rust preview did neither, so the terminal split
the cluster at the ZWJ and the cursor column was computed from summed
per-codepoint widths (4 instead of 2).
- The preview sends ?2027h on entry and ?2027l on exit like vaxis.
- tui::gwidth follows vaxis's unicode width rules per grapheme cluster
(VS15/VS16, emoji presentation, regional-indicator pairs) using the
ghostty-unicode emoji table; the preview's print path uses it.
+list-colors and +list-keybinds pretty output (also using gwidth) stays
byte-identical to /usr/bin/ghostty at widths 40/80/132.
Test Plan:
- cargo test -p ghostty-cli --test list_themes_pty
zwj_emoji_cluster_is_drawn_whole_in_search_box
- cargo test --workspace --no-fail-fast
Windows was previously only compile-checked. With Wine 11 (staging)
and mingw available, scripts/windows-wine-test.sh (`just
test-windows-wine`) builds expat/FreeType/fontconfig for mingw under
target/wine-deps and runs the test suites of ghostty-vt, unicode,
datastruct, input, os, config, terminal, crash, termio and cli under
Wine (~2,700 tests). New termio/tests/exec_windows.rs drives real
cmd.exe children over ConPTY through Termio (output, exit codes,
typing, 120 KiB writes, stop, start failure). Fixes found: Windows
paths from fs::canonicalize leaked the \\?\ prefix (new
ghostty_os::path::realpath strips it like Zig); ghostty-font compiles
hb-ft for bundled HarfBuzz on Windows; ~25 tests had Unix assumptions.
Wine limitations are ignored with reasons (ResizePseudoConsole stub,
no POSIX rename over existing files) - docs/rewrite/notes/windows-wine.md.
+list-themes preview parity (former KNOWN_DIFFERENCES rows 5-9): the
search box ports vaxis TextInput (word navigation and editing bindings,
grapheme-wise editing), ASCII-only case folding, light initial colors
until terminal reports arrive (no COLORFGBG), and load errors end the
preview with exit 1; PTY tests compare with /usr/bin/ghostty.
Test Plan:
- just test-windows-wine
- cargo test -p ghostty-cli --test list_themes_pty
- cargo test --workspace --no-fail-fast (3601 passed)
