[Unreleased]

[0.30.0] — 2026-05-25

Changed

Breaking: ghostel_cmd (shell helper) now emits OSC 52;e instead of OSC 51;E. Libghostty parses OSC 51 into an action the standard handler ignores, so the elisp-eval extension never reached ghostel's callback through normal action dispatch — the old code worked around this with a post-write byte scanner. The extension now rides on OSC 52 with a reserved kind byte (e), which libghostty dispatches directly to ghostel's handler. Scripts that hand-roll the legacy \e]51;E…\e\\ sequence will silently no-op; update to \e]52;e;…\e\\ or call the bundled ghostel_cmd helper. The post-write byte scanner is gone; the OSC 52 path is parsed by libghostty and now reassembles payloads split across read boundaries (slow producers, SSH).
Rendering now tracks scroll position and row eviction via libghostty's pin/page primitives instead of the previous heuristic. The old method had corner cases that triggered unnecessary full rebuilds; the new path keeps incremental updates correct across scrollback growth and eviction.

Fixed

ghostel-next-hyperlink / ghostel-previous-hyperlink now dedupe by OSC 8 id=, so a single logical URL split across multiple cell runs (e.g. a URL wrapped across rows inside an ASCII box) is visited once instead of once per chunk. As a side effect, two adjacent cells pointing to different OSC 8 hyperlinks no longer merge into a single style run that clobbered the second link's text properties. Fixes #125.
M-<punct> and M-<digit> keys (e.g. M-., M-/, M-;, M-1) no longer drop silently when libghostty's encoder returns no output. The raw fallback in ghostel--raw-key-sequence previously only covered meta + lowercase a–z; it now emits ESC + char for the full printable ASCII range, matching legacy alt encoding (zsh/readline M-. → insert-last-word, etc.).
Scrollback eviction no longer drops rows incorrectly when the active pin lands at the top of the screen — found via property-based testing. Related viewport rendering paths were hardened against over/underflow.

Internal

Property-based renderer testing via Hypothesis (test/hypothesis/), with CI replay of captured failure cases as regression tests.
Renderer hardening: debug assertions on rows_in_buffer, over/underflow guards, consolidated renderer tests, CSI 3J same-count refill regression test, fix for the debug finalizer setup.
Emacs function registration refactored to be declarative with the function body next to its metadata, and link_id folded into CellProps so OSC 8 metadata lives in one place.
EMACSFLAGS now forwarded into the Hypothesis driver and small development utilities added under tools/.

[0.29.0] — 2026-05-23

Added

ghostel-comint-mode (and global-ghostel-comint-mode) replaces ansi-color-process-output with a full libghostty VT parser as a comint preoutput filter. Handles truecolor / 256-color SGR, italic / faint / strikethrough / overline, curly / dotted / dashed / double underline (including colon-separator forms), underline colour, OSC 8 hyperlinks (reusing ghostel-link-map so clicks dispatch by URI scheme), OSC 7 working-directory reports, and silently consumes DCS / APC / SS3 without leaking bytes. Unstyled runs inherit the comint buffer's default face; inverse is emitted as :inverse-video t. When font-lock-mode is on, the filter swaps face for font-lock-face to survive font-lock's unfontify pass. Ref #278.
ghostel-glyph-scale-floor buffer-local defcustom (number, 0.0–1.0, default 0.0) clamps the computed glyph scale from below. At 0.0 the existing strict-grid behaviour is unchanged; at 1.0 CJK and other fallback glyphs render at natural font size at the cost of slightly taller rows. Being buffer-local, different ghostel buffers can use different settings. Closes #298.
Semi-char mode now forwards M-<digit>, M-<punct>, and M-<uppercase> (plus M-SPC) to the terminal. Previously the M- loop only covered ?a..?z, so M-., M-1, M-/, M-;, etc. fell through to Emacs global commands instead of reaching the shell. CSI/SS3 escape-sequence prefixes (M-[, M-O) are still left to TTY input decoding. Fixes #314.

Fixed

ghostel--filter-soft-wraps was O(n²) due to one-character-at- a-time string concatenation, causing multi-second freezes when copying large selections (e.g. full scrollback) with M-w in copy mode. Replaced with a chunk-collection approach.
Skip rows-only resize while a minibuffer is active. Fish (and other shells with fish_handle_reflow on) repaints its prompt on every SIGWINCH; a consult-buffer / M-x cycle grew then shrank the body of the window showing the ghostel buffer, producing two prompt repaints in quick succession. The deferral hits the no-change branch after the minibuffer closes. Col changes and non-minibuffer vertical resizes still propagate so $LINES stays accurate. Fixes #268.
CRLF normalization is now skipped on the alternate screen. Apps like tmux, vim, and less emit VT-correct sequences where a bare \n means LF; normalizing them to \r\n corrupted their layout. Detection covers all three alt-screen entry modes (DECSET 47 / 1047 / 1049).
Default-styled text is no longer invisible on the Linux framebuffer TTY. ghostel--face-hex-color only recognised the literal "unspecified" string as unset, so on a TTY frame where the default face reports "unspecified-fg" / "unspecified-bg" it fell through to a "#000000" fallback for both attributes, collapsing fg and bg to black-on-black. All three sentinel strings are now recognised; the last-resort fallback splits into white for :foreground and black for :background. Fixes #297.

Changed

Removed ghostel-readonly-recenter — no longer needed now that scrollback is materialized into the buffer. Fixes #310.

Internal

Switched the Zig module from libghostty-vt's C API to the Zig API. OSC actions are now routed through a custom GhostelHandler that wraps libghostty's standard terminal handler and overrides the OSC arms (semantic_prompt, color_operation, report_pwd, clipboard_contents, show_desktop_notification, progress_report). This deletes ~395 lines of parallel byte-scanning code in module.zig in favour of reading ghostty's parsed Command values directly. Only OSC 51 still uses a bespoke scan since it is ghostel's elisp-eval extension.
Style-to-face translation extracted into src/style_face.zig and shared between the renderer and the ghostel-comint stream filter so they stay in sync.
Debug builds use DebugAllocator for corruption and leak detection; allocator is deinit'd on atexit and the false-positive leak check was tightened. Allocators are now injected via Zig's best-practice pattern: terminal stores alloc at init, Renderer/RowContent accept alloc parameters (unmanaged pattern), and module.zig has a single top-level alloc binding instead of scattered c_allocator references.
Zig refactors: Terminal renamed to GhostelTerm to avoid confusion with ghostty's Terminal type; Renderer stores gt.Terminal; the force_full argument is replaced by setting the render state dirty; debug-mode userptr freeing is generalized beyond GhostelTerm; Zig log output also goes to stderr.

Added

Multi-terminal navigation commands: ghostel-next, ghostel-previous, ghostel-list-buffers, plus project-scoped variants ghostel-project-next, ghostel-project-previous, and ghostel-project-list-buffers for cycling and picking among ghostel buffers. Project membership is configurable via the new ghostel-project-buffer-scope defcustom.

Changed

Font metrics are now cached during redraw, avoiding repeated font-attribute lookups per frame.

Internal

Tests run in parallel via per-file Make targets, with stamps under .build/tests/. Recommended invocation: make -j$(nproc) all (or -j$(sysctl -n hw.ncpu) on macOS). Wall-clock improvements on a warm cache: test 12.5s → 6.6s, test-native 11.2s → 7.8s, all 10.4s → 8.4s. New EMACSFLAGS variable lets callers inject load paths.
The monolithic ghostel-test.el was split into 16 per-topic ghostel-*-test.el files plus a shared ghostel-test-helpers.el. Native-only tests carry :tags '(native); the runner selects via (tag native) / (not (tag native)) instead of a hand-maintained whitelist.
A review pass over the split fixed ~30 tests that were passing for the wrong reasons (tautological assertions, mocks of the function under test, references to symbols that no longer exist).

[0.27.0] — 2026-05-18

Added

ghostel-query-before-killing defcustom controls whether Emacs asks for confirmation before killing a live ghostel buffer or exiting Emacs while one is running. Defaults to auto: quiet at the shell prompt, queries while a command is running (via OSC 133 C/D markers). Set to t for always-on confirmation, nil to restore the previous never-query behavior. Closes #288.
ghostel-macos-login-shell defcustom (default t on Darwin) wraps the shell via /usr/bin/login -flp $USER so ~/.zprofile and ~/.bash_profile are sourced, matching Terminal.app and Ghostty. Skipped for TRAMP, non-Darwin, and ghostel-exec. ghostel-shell now also accepts a list form (program + args) so users can pass extra flags like '("/bin/zsh" "--login") on any platform. Fixes #285.
ghostel-prompt-regexp defcustom provides a prompt-detection fallback for ghostel-input-start-point and ghostel-beginning-of-input-or-line when OSC 133 shell integration isn't available (raw zsh, Python REPL, sqlite3, ssh into unprovisioned hosts). Default recognizes $ # % > >>> and themed prompts (λ ❯ ➜ →). OSC 133 still wins when present.
Public cursor-state API for integrations: ghostel-input-start-point, ghostel-cursor-point, and ghostel-point-on-cursor-row-p. Pure state reads — safe to call from any input mode.

Fixed

Bash's OSC 7 cwd report now uses the real kernel hostname via ${var@P} on \H (bash 4.4+) instead of $HOSTNAME. Toolbox and container runtimes export $HOSTNAME with a value that disagrees with gethostname(2), so Emacs's (system-name) saw a mismatch and TRAMP fired on every cd. Falls back to $HOSTNAME on bash <4.4. Fixes #276.
OSC 7 is now emitted after any user-supplied PROMPT_COMMAND / precmd_functions entries, so competing emitters (e.g. Fedora's /etc/profile.d/vte.sh) can no longer overwrite ghostel's cwd report and cause buffers to be misclassified as remote.
Auto-composition is now disabled on TTY frames to fix the off-by-one column drift caused by emoji + VS-16 grapheme clusters (e.g. 🗂️) — Emacs's char-width reports 1 while VS-16-honoring terminals paint 2 columns, desyncing the TTY screen cache. GUI frames are untouched. Fixes #274.
Glyphs that occupy a narrow cell but have an empty cell after them are now promoted to wide on render, so emoji and other ambiguous-width sequences land in the right column even when upstream width tables disagree with the terminal.

Changed

Internal Zig refactor of adjustGlyphs and putTextProperty; no user-visible change beyond the width promotion above.
Removed dead debug entry points (fnDebugState, fnDebugFeed) and unused render state fields.

[0.26.0] — 2026-05-13

Added

ghostel-bold-color defcustom mirrors Ghostty 1.2.0's bold-color: bold text with palette colors 0-7 is mapped to the 8-15 bright slot when set to bright (the default), or rendered in a fixed face/color when set to a color spec. Existing terminals pick up the change live.

Changed

S-<insert> is bound to ghostel-yank, matching the conventional alternative-paste binding in browsers, terminal emulators, and file managers. In the same pass, semi-char and read-only maps layer <remap> <yank> so any key Emacs binds to yank globally — s-v on macOS plus user rebinds — routes through ghostel-yank without per-key entries. C-y stays explicitly bound so user rebinds of the global yank key cannot break ghostel paste; line mode keeps Emacs's regular yank so paste lands in the input region. Closes #263.
ghostel-readonly-RET-or-exit-and-send now honours ghostel-readonly-fast-exit when point is on a hyperlink: read-only mode exits first (capturing the URL beforehand, since exit moves point and file:// / fileref: links switch buffers), then the link is opened. Previously RET on a hyperlink left the buffer in copy mode.

Fixed

Exiting read-only modes (copy, Emacs) no longer flickers. The viewport snap-back to the live terminal cursor used to schedule an async redraw; in the gap, Emacs would observe point at point-max and recenter, only for the timer to anchor the window back a few ms later. The redraw is now synchronous, so the window is anchored to the active viewport before redisplay runs. Fixes #269.
Upgrading the elisp package ahead of the native module no longer requires two restarts. build.zig writes a ghostel-module.version sidecar next to the binary, and ghostel--load-module consults it before module-load and refuses to map a stale .so — so a fresh install loads in the same Emacs process. The interactive version check also runs unconditionally on existing installs without a sidecar, so M-x ghostel surfaces the install prompt instead of only warning. Fixes #256.

[0.25.0] — 2026-05-11

Added

ghostel-mouse-drag-input-mode defcustom: a bare left click in semi-char mode no longer freezes the buffer into copy mode on press — it only focuses the window and sets point, matching standard Emacs behavior. A drag switches input mode on release so streaming output cannot clobber the selection; the target mode is copy (default; freezes redraws, selection is rock-solid), emacs (terminal keeps streaming, buffer becomes read-only), or nil (stay in semi-char; scrollback selections still survive, selections over live-redrawn rows can be lost). Closes #257.
ghostel-module-directory defcustom selects where the compiled native module lives. Defaults to the package directory (current behavior). Set it to a path outside the package manager's tree (e.g. elpaca's repos/ dir, which gets deleted on rebuild) to keep the artifact stable across rebuilds. M-x ghostel-module-compile builds in the resource root and moves the artifact into the configured directory.
ghostel-password-prompt-debounce defcustom (default 0.2s). Ghostel's canonical+!echo heuristic is checked on every redraw (sub-100ms), so short-lived termios flips that ghostty's 200ms poller silently misses became user-visible read-passwd popups in ghostel. The rising edge is now debounced: the source chain only runs if the heuristic still reports password mode at the deadline. Sub-debounce flickers leave nothing behind except a brief mode-line indicator flash, matching ghostty's transient lock-icon UX.

Changed

ghostel-download-module and M-x ghostel-module-compile now write to a sibling temp file and rename-file it into place. Renaming swaps the directory entry to a fresh inode, so any Emacs still holding the previous file mmap'd retains a valid mapping — updating the native module is safe under a running Emacs and no longer risks crashes on the next code-resolution. Fixes #247.
Native module internals: function-registration table reworked for readability and alphabetical ordering; error/logging helpers unified; ergonomic variadic Env.f("fn", .{…}) replaces the per-arity callN family; remaining legacy interop usage removed. No user-visible API changes, but the Elisp/native pairing changes — the bundled ghostel-module-version is bumped and ghostel--minimum-module-version is now 0.25.0. Use M-x ghostel-download-module after updating ghostel.el.

Fixed

An open read-passwd minibuffer that ghostel opened auto-cancels on the falling edge of the heuristic. When the foreground program exits (e.g. the user kills sudo with C-c C-c sending Ctrl+C), the prompt now disappears with it instead of waiting for the user to dismiss it. Three gates ensure ghostel only aborts its own minibuffer (active-flag, minibuffer depth, and the minibuffer-buffer identity captured at open time), so unrelated concurrent minibuffers are never closed.

[0.24.0] — 2026-05-10

Added

OSC 133 imenu integration: each shell prompt with OSC 133 A/B/C markers becomes an imenu entry of the form <cwd> <command>, with the target landing on the prompt prefix's start. Composes with consult-imenu, imenu-list, evil's ]m/[m, etc. The cwd is captured at command-start (OSC 133 C) and tracked chronologically, so prompts issued before a cd keep the correct directory in their imenu label. Selecting an entry leaves line and copy modes untouched; only semi-char and char modes switch to Emacs mode so point can move.
ghostel-readonly-fake-cursor: shows a thin hint cursor at the live terminal-cursor position when point has moved away in copy or Emacs mode, so the next-output spot stays visible while the user reads scrollback. Faces ghostel-fake-cursor (hollow) and ghostel-fake-cursor-box (solid) are user-customisable; the hollow box uses :line-width (-1 . -1) to stay inside the character cell and not reflow the line. Updates are driven by pre-redisplay-functions installed buffer-locally on read-only entry — no post-command-hook overhead.
Click-to-focus in semi-char mode no longer drops the press when no app is tracking the mouse. Left mouse-1 falls back to mouse-drag-region / mouse-set-point / mouse-set-region when no DEC mouse-tracking mode (1000/1002/1003) is active, so click-set-point and drag-to-select work in any input mode. (Refined further in 0.25.0 by ghostel-mouse-drag-input-mode.)
ghostel-detect-password-prompts — defcustom (default t) gating the entire password-prompt detector. ghostel-compile binds it to nil buffer-locally because compile buffers run with stty -echo to avoid double-echoing the command, which puts the pty into the exact canonical+!echo state the libghostty heuristic matches — leaving detection on would pop a read-passwd minibuffer at the start of every compile.
M-x ghostel-debug-password-events-show — view the last 32 password-prompt rising edges with the detection arm that fired (zig or regex), the cursor row text, and the buffer's remote-shell state. Capture is enabled by M-x ghostel-debug-start; the events buffer survives ghostel-debug-stop.

Changed

ghostel-password-prompt-regex now defaults to comint-password-prompt-regexp (the same regex M-x shell, M-x term, and eshell use). The previous default ([Pp]ass$?:word\|phrase$[^:]*:[ \t]*\') was too permissive and caused the false-positive class fixed below. Users who want to extend the regex should prefer customizing comint-password-prompt-regexp itself (BEFORE loading ghostel) so other Emacs facilities benefit from the same change.
ghostel--password-prompt-detected-p now returns nil or a symbol (zig or regex) identifying which arm fired. Truthiness is unchanged for callers that treat the return value as a boolean.
Wide-char / emoji rendering is now handled in the native module rather than by an elisp pixel-compensation pass. The renderer reports glyph adjustments directly, so emoji-heavy output no longer trips the string-width vs. pixel-width divergence that used to overflow the window. Eliminates the ghostel--has-wide-chars / ghostel--compensate-wide-chars round-trip on every redraw.
Native module switched to strict Zig error handling: bare catch {} swallow sites in color, PWD-update, and render-state paths now log to *Messages* (or signal) with the unified ghostel: [function] failed: [error] pattern. Cursor tracking no longer goes through accessor methods that clobbered render state; the renderer publishes cursor position as buffer-local variables matching what was rendered, which removes a class of subtle bugs.

Fixed

Spurious read-passwd minibuffer prompts when the terminal cursor row happened to end in Password: / passphrase: — typing echo Password: at a local shell prompt would pop a password prompt because the regex fallback ran unconditionally whenever the libghostty heuristic returned nil, and the regex itself was anchored only at end-of-line. The fallback regex now defaults to comint-password-prompt-regexp (structurally anchored at start-of-line or after curated trigger words), and the fallback only runs when ghostel--remote-shell-p indicates a remote shell — local raw-mode TUIs (vim, less, htop) don't risk false positives from coincidental cursor-row content. Fixes #244.
consult-line, consult-imenu, and other goto-char jumps in line mode no longer snap back to the live cursor. The minibuffer that consult opens resizes the ghostel window twice (open + close); each resize forced a redraw whose anchored-window predicate ignored window-point, so the closing resize re-anchored the window and yanked point back to the live cursor. The predicate now also checks window-point against the anchor.
Several evil-ghostel operator and motion bugs in multi-line TUI input and single-line shell prompts: dd / cc on a non-cursor row of a multi-line input (pi, ipython, prompt_toolkit) now deletes the line at point instead of the last line; cw lands at the start of the deleted range, not at column 0; dw on a single trailing space treats it as content in single-line ranges; 0 / ^ skip the shell prompt prefix on prompt rows and fall through to the original motion on scrollback / output rows; ^ / $ / 0 followed by i preserves the navigated column across scrollback; column navigation in normal state survives idle redraws on the cursor's line; evil-replace's paste count matches its delete count when trailing whitespace is stripped. Underneath: cursor delta math now subtracts scrollback before comparing buffer to viewport rows, and a new evil-ghostel--shadow-cursor models the pending terminal cursor between PTY-bound key emits and their echo back through the redraw. Fixes #218.
<mouse-2> in semi-char or copy mode no longer drops the click when no app is tracking the mouse. Middle-click now feeds gui-get-primary-selection to ghostel--paste-text (bracketed paste at the live prompt) when no tracking mode is on, matching the standard X primary-selection paste on Linux. In copy / Emacs mode with ghostel-readonly-fast-exit on, the click exits to the prior input mode first so the paste lands at the prompt; with fast-exit off it pastes in place, mirroring ghostel-yank / C-y.
RET in copy mode no longer dies in text-read-only after ghostel-mouse-press-or-copy-mode flipped the buffer into copy mode on a focus click. RET now exits read-only mode (when ghostel-readonly-fast-exit is on) and forwards a CR via the encoder; hyperlinks under point still call ghostel-open-link-at-point as before. C-c C-l was renamed to C-c M-l so the parent map's ghostel-line-mode binding is no longer shadowed. Fixes #251.

[0.23.0] — 2026-05-08

Added

Eat-style input modes. Five modes replace the old semi-char / copy duality: semi-char (terminal-focused default), char (send-everything, including most Emacs prefixes), emacs (live but read-only — buffer keeps streaming while isearch, occur, M-x, mark + M-w all work over the same vocabulary that reads any Emacs buffer), copy (frozen, point-based navigation), and line (shell-style local edit, send whole lines on RET, with filename / env / executable / pcomplete / bash-completion-backed TAB completion, history ring on M-p / M-n, C-c C-c interrupt, and C-d EOF on empty input). Mode switches live in a slim base map so they work from every live mode: C-c C-j semi-char, C-c M-d char, C-c C-e emacs, C-c C-t copy, C-c C-l line, M-RET escape from char mode. Prompt navigation (C-c M-n / C-c M-p) auto-enters Emacs mode so the terminal keeps running while the user jumps between prompts. Line mode discovers the prompt via the terminal cursor (new ghostel--cursor-row-char-offset Zig binding that walks the cursor row's cells so wide / box-drawing glyphs map correctly), refined by OSC 133 markers when present, so it works in REPLs and shells without integration loaded. README gains an "Input modes" section and evil-ghostel now gates on semi-char specifically. Closes #40.
ghostel-compile is now read-only by default, mirroring M-x compile: g reruns, n / p walk errors, RET jumps, C-c C-c jumps, C-c C-k interrupts. C-u M-x ghostel-compile opens a writable ghostel terminal (the previous default); useful for htop, less, read -p, test prompts. Two new commands flip a buffer between states mid-run without restarting: ghostel-compile-switch-to-interactive (C-c C-j) and ghostel-compile-switch-to-readonly (C-c C-e). mode-line-process shows :run / :run/i so the current state is visible at a glance. ghostel-recompile and M-x revert-buffer both preserve the launch mode of the source buffer; next-error / M-g n / M-g p work mid-run in either variant. ghostel-compile-global-mode advice now routes compilation-start CMD t to a writable ghostel terminal — callers asking for the comint variant still get a real TTY, just rendered by ghostel.
Password prompt detection. When sudo, ssh, gpg, passwd, etc. ask for a password ghostel pops up read-passwd and sends the answer through the PTY — the keystrokes never flow through Emacs's normal key pipeline, so the password does not land in view-lossage, the recent-keys ring, or any keyboard-macro recording. Detection mirrors libghostty's heuristic (the slave tty is in canonical mode with echo off) via a tiny tcgetattr Zig binding, with a regex fallback on the cursor row when the local tty's echo state can't be observed (remote ssh, programs that don't toggle echo). Mode-line shows 🔒Password while a prompt is open, the wire copy of the password is clear-string'd immediately after the send, and wrong-password retries auto-detect via cursor movement. Customize ghostel-password-prompt-functions — a chain of (ROW) -> string-or-nil sources tried in order — to plug in auth-source (or Keepass / pass / etc); the defcustom docstring includes a TRAMP-aware auth-source-pick-first-password example. PR #241.
ghostel-debug-ghostel, a wrapper around M-x ghostel that installs self-removing advice on ghostel--spawn-pty and ghostel--start-process to capture program / args / geometry / stty-flags / extra-env / process-environment, the wrapper command list passed to make-process (caught via cl-letf* on make-process so TRAMP's file handler can't rewrite it before capture), per-phase spawn timings, the first ~16 KB of PTY output as a (timestamp . chunk) event log, and the first ~64 sends. ghostel-debug-info renders the capture on a single chronological timeline (sends and PTY output interleaved) and grows a TRAMP section with tramp-version, tramp-terminal-type, the resolved tramp-direct-async-process, multi-hop length, and the local-vs-toplevel TERM divergence diagnostic that surfaces when tramp-local-environment-variable-p would silently strip the pushed TERM. C-u M-x ghostel-debug-info on a remote buffer additionally runs a single-round-trip remote probe (infocmp, xterm-ghostty / xterm-256color terminfo, ~/.local/share/ghostel/terminfo paths, /bin/sh identity, remote bash --version, $INPUTRC, and the first 80 lines of ~/.inputrc). All capture lives in ghostel-debug.el — plain M-x ghostel sessions are unaffected.
Local "Key encoding (legacy mode)" section in ghostel-debug-info that probes a fresh terminal for the chords commonly cited in inputrc reports (C-Backspace, M-f, C-M-f, C-M-v, …) and shows the resulting bytes, mirroring ghostel--send-encoded's encoder + raw fallback so the output matches what a real keystroke produces.
repeat-mode support for prompt and link navigation: C-c C-n C-n C-n cycles hyperlinks, C-c M-n M-n M-n cycles prompts (bare n / p work after releasing the modifier). Internally, eight keymaps in ghostel.el are converted from let / define-key blocks to defvar-keymap; compat 30.1.0.1 is added to Package-Requires so defvar-keymap is available on Emacs 28.

Changed

C-M-<letter> chords (C-M-f, C-M-v, …) are now bound in ghostel-mode-map and routed through libghostty's encoder so readline .inputrc rules like "\e\C-f": dump-functions actually fire. Without the binding, Emacs's forward-sexp / scroll-down-command ran instead of reaching the shell. Fixes #239.
Remote spawns now apply stty sane as a baseline (matching vterm) instead of the prior per-spawn flag list that omitted echo on the remote path without ghostel-tramp-shell-integration. Any upstream that left the PTY with echo cleared (TRAMP env stripping, custom remote /etc/bashrc, old bash readline) no longer produces silent input on the remote shell. All five spawn paths share a single ghostel--default-stty constant. Fixes #224 (third iteration).
ghostel--set-buffer-face now caches the last (FG . BG) pair and short-circuits the face-remap round-trip when the colors haven't changed. The render path called this on every dirty redraw, and face-remap-remove-relative / face-remap-add-relative each call force-mode-line-update internally — measured at ~960 FMLU per 5s with two visible buffers running spinners, dropping to ~50 after the cache. The visible symptom was the minibuffer flickering and C-g / RET taking several attempts to land while output was streaming.

Fixed

ghostel-next-prompt / ghostel-previous-prompt now land correctly with the realistic two-property ghostel-prompt / ghostel-input row layout. ghostel--prompt-input-start used skip-chars heuristics that jumped past the last char + newline for any input ending in a single-char arg (e.g. echo b) and landed on the last word for multi-word commands; previous-prompt failed to recognize point inside a ghostel-input region or at the start of input as "still on the current prompt" and snapped back to the same prompt instead of the prior one.
C-g in semi-char and char input modes now reaches ghostel-send-C-g rather than the raw ^G lambda installed by ghostel--define-terminal-keys. The terminal-key loop ran on the per-mode child maps and shadowed the parent's C-g binding, re-introducing #200 — deactivate-mark and the quit-flag clear were skipped. The loop now skips ?g, and char mode binds it explicitly.
ghostel-readonly-copy (M-w / C-w) and the copy-mode branch of ghostel-xterm-paste now honour ghostel-readonly-fast-exit nil instead of unconditionally exiting copy/Emacs mode on those keys.
ghostel-readonly-copy deactivates the mark like kill-ring-save does, so M-w / C-w no longer leaves the region highlighted when ghostel-readonly-fast-exit is nil. Closes #238.
RET on a ghostel--detect-urls-linkified cell no longer hijacks the keystroke away from the PTY in the default terminal mode. RET is dropped from ghostel-link-map (text-property keymaps outrank even emulation-mode-map-alists) and bound on ghostel-copy-mode-map instead, so click is still a real click in any mode but RET routes to the local map. Link detection on the cursor's own row is now skipped regardless of OSC 133 state, so REPLs and shells without integration loaded (Gemini CLI, raw bash, …) no longer linkify the typed command.
In evil normal state, output that grew scrollback no longer leaves point above the new prompt. The around-redraw advice used to restore point by buffer position; it now tracks the buffer line where the previous redraw placed point at the terminal cursor and lets the renderer's new placement stand when the user has not navigated. Closes #228.
ghostel-debug-info no longer raises void-variable on Emacs 28/29. tramp-direct-async-process was added in Emacs 30.1's bundled TRAMP; the variable read is guarded with boundp and a forward defvar quiets byte-compile-error-on-warn in CI.

[0.22.1] — 2026-05-04

Fixed

Loading ghostel.el no longer prompts to download or compile the native module under any circumstances. Previously ghostel.el consulted ghostel-module-auto-install at load time and could open an interactive read-char-choice prompt — this hung Emacs 31 user-lisp/ auto-byte-compile and similar harnesses where a user (setq ghostel-module-auto-install nil) had not yet been evaluated. Module installation now happens only on an explicit user action: M-x ghostel, M-x ghostel-download-module, or M-x ghostel-module-compile. When the module is missing at load time the package issues a display-warning instead. Closes #231.
No-echo on remote shells launched from a TRAMP default-directory (ghostel-tramp-shell-integration nil). The previous fix rebound tramp-terminal-type, which only takes effect on the generic tramp-handle-make-process path; the ssh-method path (tramp-sh-handle-make-process) ignores it. In addition, when the local default-toplevel process-environment already has TERM=xterm-ghostty (e.g. Emacs launched from ghostty), tramp-local-environment-variable-p strips ghostel's pushed TERM as "ambient", and the remote shell inherits TERM=dumb from TRAMP's connection shell — disabling readline/ZLE/fish line editing.

The per-spawn /bin/sh -c wrapper now sets TERM itself on the remote, after probing for xterm-ghostty terminfo via infocmp. Single path covers auto-integration (TERMINFO pushed), manual install (system or ~/.terminfo), and the bare case (fall back to xterm-256color so echo works). The bogus local TERMINFO path is no longer pushed to the remote. Closes #224 again.

Added

Manual remote-integration setups can now drop the bundled xterm-ghostty terminfo at ~/.local/share/ghostel/terminfo/ alongside the shell scripts (scp -r etc/terminfo/{x,78} from the local package). TRAMP-spawned remote shells detect it and prepend the directory to TERMINFO_DIRS automatically — no tic, no touching ~/.terminfo. README "Option 2: Manual setup" updated with the one-shot install recipe.

[0.22.0] — 2026-05-04

Added

ghostel-pre-spawn-hook, run inside ghostel--spawn-pty just before make-process with process-environment dynamically bound to the about-to-be-spawned env. Hook functions can setenv to inject entries the child inherits. Intended for integrations like with-editor — with a with-editor-setup-environment exposed upstream, users can wire Magit's EDITOR plumbing into ghostel buffers via (add-hook 'ghostel-pre-spawn-hook #'with-editor-setup-environment). Fires for both ghostel/ghostel-project and ghostel-exec spawns; ghostel-compile has its own make-process and is not covered.
evil-ghostel-escape controls how ESC is routed in evil insert state: auto (default) inspects DECSET 1049 to send ESC to the terminal in alt-screen apps (vim, less, htop, …) and otherwise fall back to evil-normal-state; explicit terminal and evil values force one or the other. A toggle command with numeric prefix support is also bound. The terminal-bound ESC snaps to the live viewport like every other typed key; the evil-bound fallback lands on evil-force-normal-state when the user's <escape> binding is missing or a chord prefix (#215).
make bench-e2e (and a --e2e flag on run-bench.sh) measures whole-pipeline throughput by installing each backend's production filter+sentinel on a cat subprocess and waiting for full quiescence, so the wall clock reflects what users actually feel (including ghostel's delayed-redraw link detection / anchoring, vterm's regex split + decode loop, and eat's deferred queue). Composes with --quick, --size, --iterations, and the backend-skip flags.

Changed

The Zig native module has been broadly refactored ("Zigify everything"): libghostty calls are wrapped to be return-value oriented rather than out-pointer oriented, errors propagate via Zig's try/catch and error unions instead of C error codes, optional absence is distinguished from real errors, and per-error logging/handling is consistent across the module (#217). This is internal — no user-visible API changes — but bumps the minimum required native module version, so update both ghostel.el and the prebuilt .so/.dylib together.
Render code is reorganised around a single property-run abstraction (prompt cells, input cells, and ordinary content all flow through the same path), and uses a new internal FixedArrayList to cut per-row allocation overhead. Adds an Emacs↔Zig logging/debugging layer used during the refactor and available for future native-module work.

Fixed

Launching M-x ghostel from a TRAMP default-directory (e.g. after find-file /ssh:host:) now produces a usable remote shell. Previously TRAMP's make-process' handler reset TERM to tramp-terminal-type' (default "dumb"'), which caused bash/readline, zsh/ZLE, and fish to disable interactive line editing on the remote: typed characters didn't echo, although Enter still submitted the line. Ghostel now rebinds tramp-terminal-type' for its remote spawns to xterm-256color' (or xterm-ghostty' when `ghostel-tramp-shell-integration' has pushed the bundled terminfo), restoring echo and line editing (#224).
Shell integration survives prompt themes and rcfile assignments that overwrite PROMPT/PS1/fish_prompt after ghostel sourced its bootstrap. The OSC 133 A/B markers are now (re)installed every prompt cycle — modeled on ghostty's own zsh/bash/fish integrations — so powerlevel10k, agnoster, Pure, oh-my-zsh / prezto add-zle-hook chains, bash PROMPT_COMMAND reassignments, and fish themes loaded via conf.d/ no longer strip the prompt-range markers. Without those markers, the file-path link detector linkified user-typed cells and the link keymap's RET binding shadowed the normal terminal RET in tty Emacs — pressing RET on a typed cd some/path opened the link instead of executing the command (#199).
New terminals no longer briefly flash with libghostty's default colors before ghostel applies the Emacs theme. A regression test guards against the flicker reappearing (#219).
ghostel-keymap-exceptions now also excludes special keys (<return>, <tab>, <f1>, …, including their S-/C-/M-/ C-S-/M-S-/C-M- variants). The special-keys binding loop in ghostel-mode-map was missing the exceptions check that the C-<letter> and M-<letter> loops had, so users could not exclude e.g. C-<return> or C-M-<down> (#210).
ghostel-download-module no longer segfaults when the module is already loaded. Calling module-load on a path whose shared library is mapped into the running Emacs makes dyld/ld.so return the existing handle and resolve emacs_module_init via dlsym on the stale image. Ghostel now skips the second module-load when the module is already featurep'd and tells the user to restart Emacs to pick up the new version (#78).

[0.21.0] — 2026-05-01

Added

ghostel-spinner-progress, a built-in handler for ghostel-progress-function that animates mode-line-process via spinner.el during indeterminate progress (e.g. while Claude Code is working) and shows percentage text for determinate states. spinner.el is a soft dependency: when it is on the load-path at ghostel load time, ghostel-progress-function defaults to this handler; otherwise the existing ghostel-default-progress text indicator is used. New ghostel-spinner-type defcustom (default progress-bar) selects the spinner style.

Changed

Resize redraw work now scales with the resized axis. Column changes still trigger a full scrollback rebuild (cell wrapping depends on width), but row-only changes only re-render the visible area and defer until after the next redraw, eliminating noticeable lag when only the height changes (24f6653).

Fixed

Claude Code's progress reports now update mode-line-process in ghostel buffers. Claude Code gates OSC 9;4 progress emission on TERM_PROGRAM_VERSION parsing as semver >= 1.2.0; ghostel advertised TERM_PROGRAM=ghostty without the version, so the gate failed and progress was silently dropped. Ghostel now also exports TERM_PROGRAM_VERSION matching the vendored libghostty pin, satisfying Claude Code's check and any other consumer that applies the same probe.
Plain-text URL/file detection no longer linkifies the cell the user is typing into. In tty Emacs, RET on a linkified cell resolved to ghostel-open-link-at-point (text-property keymap overrides ghostel-mode-map), so pressing return at a path the shell echoed — e.g. cd src/main.rs — opened the file instead of running the command. The renderer now marks OSC 133 B..C cells as ghostel-input and ghostel--detect-urls skips the prompt prefix unconditionally and the active input line. The bundled bash/zsh/fish integrations are updated to emit 133;A and 133;B from inside the prompt itself rather than back-to-back before prompt expansion, so libghostty sees a non-empty PROMPT range (c145c5e, closes #199).
OSC 51;E callbacks dispatch synchronously from the process filter rather than waiting for the next redraw timer tick. Callers like b4 prep --edit-cover write the OSC and continue, cleaning up their tempdir before deferred elisp could find-file the path; deferred dispatch produced Setting current directory: No such file or directory. Matches vterm's behavior. OSC 51;A (directory tracking) is left deferred since it has no such race (3f8846c, fixes #209).

[0.20.1] — 2026-04-29

Changed

Style-run break detection during render uses a cheap CellStyleKey rather than a full CellStyle comparison, cutting per-cell overhead on large dirty regions (81f1258).
libghostty can now be built with optimization settings independent from the ghostel module itself, so debug ghostel builds no longer drag libghostty into debug mode (5baea2d).

[0.20.0] — 2026-04-29

Added

Kitty graphics protocol support — render images inline in the ghostel buffer for both traditional non-virtual placements (timg, kitty +kitten icat, applications using direct kitty graphics) and unicode-placeholder placements (yazi, modern image previewers). All decoding, storage, and protocol parsing flow through libghostty's kitty graphics C API; ghostel queries the placement iterator each redraw and applies image overlays in Emacs. Non-PNG pixel data (RGBA / RGB / GrayAlpha / Gray) is converted to PPM (P6) for Emacs's built-in image renderer; PNGs go through libghostty's PNG-decode hook backed by vendored stb_image. Per-row slicing (:ascent 'center plus a line-height clamp on the trailing newline) keeps image rows flush even when the placeholder line's line-pixel-height is pulled above frame-char-height by a fallback font or nerd-font icon on the same line (57ef5a7).
ghostel-cell-pixel-scale controls the physical:logical pixel ratio reported to apps that probe XTWINOPS CSI 14/16/18 t. Apps like timg and yazi expect cell dimensions in physical pixels (what standalone Ghostty advertises via the OS window server's backing scale factor), but Emacs only exposes logical pixels — reporting them unscaled makes apps either fall back to half-blocks (timg) or fill many more cells than expected with upscaled, blocky output (yazi). The auto default derives a float scale from display DPI (display-pixel-width / display-mm-width compared to the 96 DPI reference); a numeric override is available for pixel-perfect parity with standalone Ghostty (57ef5a7).
File detection recognises tilde-prefixed paths (~/file.el:42) — ~ is added to the leading character class and leading anchor of ghostel-file-detection-path-regex (abae518).

Changed

OPT_SIZE (XTWINOPS CSI 14/16/18 t) is now answered by ghostel, alongside the existing OPT_DEVICE_ATTRIBUTES reply. Image- rendering tools probe these queries to detect kitty graphics support and pick image dimensions; without a response timg fell back to half-block rendering even when TERM_PROGRAM=ghostty. Cell pixel dimensions are stored on the Terminal struct and updated on every resize, and ghostel--set-size is seeded once between ghostel--new and the process spawn so the very first output (e.g. timg's transmit-and-place) reports authoritative values rather than zero (57ef5a7).

Fixed

ghostel-exec uses the universal 80×24 default when BUFFER is not displayed in any window, instead of sizing the PTY from (selected-window). The selected window had nothing to do with where the agent buffer would eventually be shown — programs ending up in a different window had to rely on SIGWINCH to recover, and TUIs that latch initial dimensions at startup rendered against the wrong size. Matches eat's behaviour; the displayed-buffer path is unchanged (a8bf9ae).

0.19.0 — 2026-04-29

Added

ghostel-debug-keypress arms a one-shot capture of the next keystroke in the current ghostel buffer and renders a paste-ready diagnostic (raw event, resolved keymap binding, every byte sent, active DEC mode flags, coalesce-buffer state) into *ghostel-debug-keypress* — enough to distinguish kitty CSI-u from legacy encoding without any new native binding (07b8438).
ghostel-debug-info gains an Environment block (env vars passed to the spawned shell — TERM, COLORTERM, TERMINFO, TERM_PROGRAM, INSIDE_EMACS, ghostel-environment overrides, and pass-through LANG/LC_*), a Size sync block (Emacs window body rows vs ghostel--term-rows vs Emacs's recorded old-body-pixel-height, with explicit verdicts for in-sync / chrome-absorbed-but-unreconciled / pending-redisplay), and a Rendering block (default face, resolved font with fallback/remap detection, line-spacing broken into buffer-local / default-value / frame-parameter, face-remapping-alist). The buffer is now read-only (special-mode, q to quit), module-file lookup works in the dev / package-vc layout, and customized defcustoms are auto-detected by comparing against standard-value (0b19011, d717732, ea594fc, e8eb2f8).
FreeBSD release artifact built via Zig cross-compile from the Linux CI runner, using the same matrix-driven -Dtarget=... pattern as aarch64-linux-gnu (81abb18).
list-buffers-directory is set to the buffer's default-directory in ghostel-mode and ghostel-compile-view-mode, and is updated by OSC 7 directory tracking — so buffer-menu / ibuffer (and any consumer that reads the variable) can categorise ghostel terminals by working directory. Mirrors shell-mode's convention (75fe69f).
tui-partial benchmark renders the static screen once, then updates only the bottom row per iteration — the workload that status bars and prompt redraws actually produce. Exposes that ghostel's per-row dirty-bit branch is 8–13× faster than full mode at 24×80 and 40×120 (6a4a069).

Changed

Native rendering rewritten. Each pass parks the libghostty terminal at max_offset - 1, which lets us track scrollback correctly across the libghostty cap by detecting eviction from the parked offset, identify scrollback-clear (CSI 3J et al.) reliably via the offset+len==total snap-back signal without per-byte VT scanning, use libghostty dirty flags directly to identify stale lines (fixes the case where promoted scrollback rows could carry outdated content), and evict old scrollback rows from the Emacs buffer in lockstep with libghostty's ring-buffer wrap. OSC 8 hyperlink handling switches from storing URI strings on every run to a lazy help-echo lookup via ghostel--native-uri-at. The Emacs buffer now always carries a trailing newline so line-math is uniform across the codebase (8e3135f).
PTY size is now captured against the buffer's window via window-screen-lines, not the selected window via window-body-height. When a theme remaps the buffer's default face — e.g. nano-light/nano-dark bumping it ~7% — the two metrics disagree and the previous capture spawned the PTY too tall, then issued a startup SIGWINCH that some TUIs (Claude Code's /tui fullscreen) mishandle. Updates every spawn / commit / reconcile site (ghostel--init-buffer, ghostel-exec, ghostel--commit-cropped-size, ghostel-compile). Closes #192 (23cdc7c, ce966eb).
Terminal size is reconciled via window-buffer-change-functions (event-driven) instead of a 50 ms idle timer. When a ghostel buffer migrates to a window of a different size (popup dismissed, +popup/raise, etc.) no Emacs-visible window-size-change event fires — only the buffer-to-window mapping changed — so the existing adjust-window-size-function machinery did not run. The hook covers the buffer's whole lifetime cleanly (387c275, b9c12ca).
README's manual ~/.bashrc / ~/.zshrc / ~/.config/fish/config.fish source gate now uses a prefix match (${INSIDE_EMACS%%,*}, fish-anchored regex) so TRAMP-rewritten INSIDE_EMACS=ghostel,tramp:VER matches. The remote-host gate adds a TERM=xterm-ghostty fallback because plain ssh cannot propagate INSIDE_EMACS without AcceptEnv configured server-side. Also updates the source-comment header in etc/shell/ghostel.{bash,zsh,fish} and adds a TRAMP canary test on tramp-inside-emacs (d3ecac0).
package-lint, checkdoc, and docquotes (a regex check for back/front-quoted non-symbols, widened from melpazoid's [A-Z]+ to [A-Z_]+ so identifiers like INSIDE_EMACS aren't skipped) now run in CI as a single Emacs 29.4 lint job; evil-ghostel.el is byte-compiled and linted alongside lisp/ (5d73106, 5321d1b).

Fixed

Coalesced single-byte input is drained before every direct PTY write from Zig (key encoder, mouse encoder, OSC 4/10/11 replies, focus events, VT write-back). Encoded keystrokes could otherwise overtake preceding self-insert bytes (0b37dae).
C-g in a ghostel buffer now also deactivates the active region, matching the side effect users expect from keyboard-quit (the inhibit-quit binding routes C-g through the keymap to ghostel-send-C-g, which previously only sent SIGINT). Closes #200 (14b4e85, 7631ea9).
IME preedit anchor stays stable during redraw — the cursor row no longer drifts while typing into an active preedit window (90f1f71).
Evil state transitions no longer wipe + rebuild the buffer once any scrollback exists. A defer in fnCursorPosition / fnDebugState / fnDebugFeed was scoped to an inner if (term.getScrollbar()) |sb| { … } block, so the viewport-restore fired before the SCROLL_BOTTOM call below it. Each call left libghostty parked at the bottom (offset+len==total), which the next redraw mistook for a scrollback-clear signal. Hoisted the defer to function scope. Folded in: a heap-fallback defer ... .free(buf) in fnUriAt was scoped to the inner alloc block and freed before makeString read through the alias — hoisted, plus a SUCCESS check on ghostty_grid_ref_hyperlink_uri so error returns no longer stringify uninitialised data (8e3135f).

0.18.1 — 2026-04-25

Added

ghostel-plain-link-detection-delay user option (default 0.1s) controls how long ghostel waits after a redraw before scanning for plain-text URLs and file paths. Set to 0 to restore the previous synchronous behavior (671d3ee).

Changed

Plain-text link detection is now deferred off the redraw path and coalesced via a single timer, so bursts of redraws collapse into one scan instead of running detection on every dirty redraw. Native OSC-8 hyperlink spans continue to be handled inside the renderer. The process sentinel cancels the pending detection timer so it cannot fire against a buffer that is about to be killed (671d3ee).
Scrollback rotation detection now snapshots the first scrollback row directly (std.mem.eql over all term.cols cells) instead of hashing the first 16 cells with FNV-1a. Removes a small collision probability and the arbitrary 16-cell sample that could miss rotation when two rows shared the same opening cells; the cached-read optimisation that skips the end-of-redraw round trip is preserved (4b1a0ba).

0.18.0 — 2026-04-24

Breaking

Repository layout reorganized. Elisp sources now live under lisp/ (the ghostel package) and extensions/ (independent evil-ghostel package); vendored headers moved from include/ to vendor/; the bundled compiled terminfo moved from terminfo/ to etc/terminfo/; shell-integration assets restructured into etc/shell/ghostel.{bash, fish,zsh} (user-sourced rc files) and etc/shell/bootstrap/ (env- hook shims for local auto-injection) (266e3e9).
Users who source ghostel's shell rc files manually from their own shell configuration must update the path: etc/ghostel.{bash,zsh, fish} → etc/shell/ghostel.{bash,zsh,fish}.
evil-ghostel is now published as a separate MELPA package. Users who relied on installing ghostel alone and getting evil integration for free must now install evil-ghostel separately. In return, package-vc-install ghostel no longer pulls evil in as a transitive dependency of the single-repo scan.
Removed the ghostel-evil compatibility shim that was deprecated in 0.13.0. Replace any (require 'ghostel-evil) with (require 'evil-ghostel) and any ghostel-evil-mode calls with evil-ghostel-mode.

Added

ghostel-environment user option (mirrors vterm-environment): list of KEY=VALUE strings prepended to process-environment before spawning the shell. Honors .dir-locals.el via hack-dir-local-variables, propagates to TRAMP remote shells, and applies to both shell spawns and ghostel-compile spawns. User entries take precedence over ghostel's own TERM/INSIDE_EMACS. Closes #176 (87c99e5).
ghostel-default face (inherits default) as the per-buffer customization point for terminal foreground/background, allowing e.g. a dark terminal inside a light Emacs without resorting to defadvice. Closes #178 (7c3fa5b).

Changed

ghostel and ghostel-project now explicitly return the buffer they create or switch to, so callers can use the buffer programmatically without relying on pop-to-buffer side effects. Closes #185 (fdfb68f).
ANSI color faces now inherit from ansi-color-* instead of term-color-*. Themes (notably modus) deliberately remap term-color-black / term-color-white to bright palette entries to keep them distinct from term.el's buffer face — that accommodation made e.g. htop's status bar render gray-on-green and unreadable. ansi-color-* is the canonical ANSI face family since Emacs 28.1 and themes customize it to the proper palette. Closes #175 (a27f2fa).

Fixed

Scrollback no longer leaves stale rows after CSI 3J (clear-scrollback) followed by enough new output to restore the same scrollback depth. A unified rebuild_pending flag now tracks all scrollback-validity signals (resize, CSI 3J, rotation hash mismatch); the surgical-trim fallback that misbehaved on reflow is replaced with a single full-erase path. Closes #160 (f5524ef).
A ghostel buffer that received output while hidden no longer shows a stale pre-hide screen on re-show. A per-window snap list populated via window-buffer-change-functions forces the next redraw to anchor to the latest output. Closes #177 (63e008f).
The first ghostel buffer in a session now respects display-buffer-alist. Fixes #179 (d33052d).
ghostel and ghostel-project reuse an existing terminal buffer even after ghostel--set-title-default has renamed it. Buffers now carry a sticky ghostel--buffer-identity set at creation time, and lookup matches on identity rather than current buffer name. Fixes #168 (465030e).
Bind [xterm-paste] to a ghostel-aware handler so clipboard pastes delivered by the host terminal (TTY Emacs with bracketed paste) reach the inferior shell instead of being inserted into the renderer-owned buffer and wiped on the next redraw. Fixes #172 (5546b97).
Meta-modified keys (M-x, M-DEL, …) now reach the terminal in TTY Emacs. TTY Emacs delivers M-<key> as an ESC prefix that consumes the meta modifier before the binding fires; the dispatch path now detects the esc-map lookup via this-command-keys-vector and re-injects meta. Follow-up to 43220db; fixes #48 (c42451e).
Fish auto-inject now installs xterm-ghostty terminfo on remote hosts via the ssh wrapper (parity with bash/zsh), and no longer leaks fish's internal vendor-conf xdg_data_dirs (with /fish appended) into XDG_DATA_DIRS for every spawned subprocess. The vendor-conf shim now chains to etc/ghostel.fish instead of carrying a drifting inline copy (d9fd009).
package-vc-install on Emacs 30.x no longer fails byte-compiling test/, bench/, and extensions/. A .elpaignore scopes recompilation to the package's lisp directory via byte-compile-ignore-files. Emacs 31 fixed this upstream (573acd97); the .elpaignore covers the un-backported case (bcba725).

0.17.0 — 2026-04-21

Added

evil-ghostel-initial-state defcustom controls the initial evil state in ghostel buffers (default insert). Replaces a hard-coded evil-set-initial-state call that fired on every ghostel buffer creation and silently clobbered user overrides. :set re-applies the value on change, and the setq-before-require path is honoured on load (5fcbb19).

Changed

Replaced ghostel-enable-title-tracking (boolean) with ghostel-set-title-function. The new option holds the function invoked on OSC 2 title changes; set to nil to disable title tracking, or to a custom function to fully override the rename behaviour (5bd67f1).

Fixed

mark now survives native redraws. The full-redraw path (eraseBuffer) previously snapped every marker to point-min, and the partial-redraw path drifted markers asymmetrically by insertion-type — so C-SPC-set marks or normal-state region commands lost their anchor on every frame (4816ece).
Evil visual selections no longer stretch to a multi-row phantom region in a buffer that is streaming output. The around-redraw advice now saves and restores evil-visual-beginning / evil-visual-end while in visual state, in addition to point (606ec4d).
Removed the evil-ghostel normal-state-entry hook that corrupted point after operator commands — yy, v..y, and v..<escape> could discard the motion and land point on the TUI cursor row. Evil's own operator/visual machinery places point correctly without the extra snap (b955dbb).

0.16.3 — 2026-04-20

Fixed

Block cursor no longer drifts up a row when a TUI parks it on an empty last row via absolute positioning (CUP). The window-point clamp from 0.16.1 is broadened via a new ghostel--cursor-on-empty-row-p native predicate so the clamp fires on both pending-wrap and empty-trailing-row conditions. Closes #157 (d4fdc8e).
The bundled ssh wrapper in ghostel.bash / ghostel.zsh no longer fails with a parse error when the user has alias ssh=… set before sourcing the integration. Uses function ssh { … } form to sidestep alias expansion. Fixes #155 (44aaf67).

0.16.2 — 2026-04-20

Added

Bundled xterm-ghostty terminfo under terminfo/ (both Linux and macOS hashed-dir layouts). Terminal sessions now set TERM=xterm-ghostty + TERMINFO=<bundled> + TERM_PROGRAM=ghostty so TUI apps that consult terminfo see ghostel's real capabilities — most notably DEC 2026 (Sync), which Claude Code needs to avoid cascading unsynchronised redraws on M-x with large scrollback. TRAMP pushes terminfo to a remote temp dir over the existing connection; outbound ssh from a local buffer is shadowed with a wrapper that installs terminfo on the remote via tic on first use (cached per-host under $XDG_CACHE_HOME/ghostel/, invalidated on libghostty bumps). New options: ghostel-term, ghostel-ssh-install-terminfo, M-x ghostel-ssh-clear-terminfo-cache (2c92f68).

Fixed

Minibuffer activation (M-x, vertico, consult) no longer repaints the shell prompt or forces full TUI redraws. Shrinks caused by the minibuffer stealing window space are treated as viewport crops instead of real resizes, suppressing the spurious SIGWINCH. Apps on the alternate screen (vim, htop, less, Claude Code) still receive SIGWINCH because they own the full viewport; selecting the ghostel window while the minibuffer is open commits the cropped size (3e8d9c7).
ghostel-compile header and early output no longer wrap at the wrong column when the compile buffer lands in a smaller window than the selected one. The VT is now reconciled to the output window's dimensions before rendering the header and before spawning the process (dcbbf1d).
M-x kill-compilation now finds and terminates a live ghostel-compile run. compilation-locs is declared buffer-locally during the run so compilation-buffer-internal-p recognises the buffer (dcbbf1d).

0.16.1 — 2026-04-20

Fixed

Block cursor no longer draws on top of the last character while the user is typing at a shell prompt. The window-point clamp introduced in 0.16.0 is narrowed to fire only when libghostty reports the cursor in pending-wrap state, exposed via a new ghostel--cursor-pending-wrap-p native function. Fixes #146 (ad8536e).

0.16.0 — 2026-04-19

Added

Desktop notifications via OSC 9 (iTerm2) and OSC 777 (rxvt notify), plus ConEmu OSC 9;4 progress reports. Notifications route through ghostel-notification-function (default uses notifications-notify with a message fallback, dispatched via run-at-time so a slow DBus broker can't stall the VT parser); progress routes through ghostel-progress-function (default shows [42%] / [...] / [err] / [paused] in the mode line). OSC 9;9 CWD reports are handled the same way as OSC 7. Closes #141 (4f7b1cd).
ghostel-compile-global-mode: opt-in global minor mode that advises compilation-start so every caller (compile, recompile, project-compile, ...) automatically runs in a ghostel buffer. Falls through to the stock implementation for grep-mode, comint, and continue=non-nil; excluded set is customisable via ghostel-compile-global-mode-excluded-modes (e7164ec).
ghostel-send-string and ghostel-send-key public API for external packages (agent integrations, custom keymaps) to drive a ghostel buffer without reaching into ghostel-- internals. The old internal ghostel--send-key is kept as an obsolete alias; the raw-byte primitive is now ghostel--send-string (5453c22).
<XF86Paste> and <XF86Copy> media keys are now bound to ghostel-yank and kill-ring-save. Previously they fell through to the global commands and got overpainted by the next redraw (65932e6).

Changed

ghostel-compile no longer types its command into an interactive shell. Each invocation spawns shell-file-name -c COMMAND directly via make-process through a PTY owned by the ghostel renderer. Multi-line scripts with embedded newlines now pass through verbatim (the old type-into-shell path interpreted each newline as RET), exit status comes from the process sentinel, and shell integration is no longer required. The banner is written to the VT before spawn so it appears live; interactive programs like htop, less, and read prompts keep working because the buffer stays in ghostel-mode during the run (e7164ec).
ghostel-recompile now re-runs into the current buffer when it holds a local ghostel-compile--command, so pressing g in a *compilation* buffer produced by ghostel-compile-global-mode reuses the buffer and window instead of opening a second one (e7164ec).
ghostel-compile opens its buffer in a non-selected window, matching M-x compile exactly. Respects display-buffer-alist, keeps focus on the caller, and quit-window disposes of the window the way users expect. Closes #122 (9846c64).
evil-ghostel point now tracks the terminal cursor in evil-emacs-state, not just insert-state — emacs-state is evil's vanilla-Emacs escape hatch and should behave like a normal terminal (f05e0db).
Large TUI redraws (Claude Code, post-resize frames) now stream in a single filter call. process-adaptive-read-buffering is disabled and read-process-output-max raised to at least 1 MB for ghostel PTYs; pre-Emacs 31 this collapses a 570 KB post-resize frame from ~9 filter calls to 1 — a ~15-second cascading repaint becomes instant. Mirrors what vterm does for the same reason. Fixes #85 (bcf2f0c).

Fixed

Child programs that enable focus reporting (Claude Code, btop, vim) now see focus-out when the user selects a different window inside Emacs, not only when the whole frame blurs. Adds hooks on window-selection-change-functions and window-buffer-change-functions in addition to frame focus. Closes #140 (ddaefbc).
Process sentinel no longer removes the focus-reporting hook globally on exit, which had broken focus reports for every other live ghostel buffer (ddaefbc).
TUI cursor no longer disappears on the last viewport row when it lands in pending-wrap state. Clamps window-point back by one when pt equals point-max so Emacs redisplay stops shifting window-start up by a row to "make it visible." Closes #138 (17fc791).
Viewport no longer snaps to the prompt when the minibuffer opens (and the ghostel window shrinks) in a scrolled-up TUI. During a resize-triggered redraw, windows that were auto-following before the resize are treated as still anchored rather than as a user scroll. Closes #127 (aa4912d).
Per-cell face properties (colours from SGR sequences) now survive when font-lock-mode is force-enabled in a ghostel buffer — e.g. Doom Emacs sets font-lock-defaults globally, which reactivates font-lock after ghostel-mode's (font-lock-mode -1). A buffer-local font-lock-unfontify-region-function neutralises the unfontify pass in both ghostel-mode and ghostel-compile-view-mode (28f5071).
evil-ghostel: entering normal state in a buffer with any scrollback no longer snaps point to row N of the scrollback region instead of row N of the visible viewport — the row offset now accounts for scrollback line count (69d4b0d).

0.15.0 — 2026-04-17

Added

ghostel-compile and ghostel-recompile: M-x compile-style workflow backed by a real PTY, so commands that need a terminal (colour output, progress bars, curses tools) work normally. Finished buffers support next-error navigation and share compile-command / compile-history with M-x compile; g recompiles in the original directory, C-u g prompts to edit the command (5280db2, d72751e).
ghostel-eshell-visual-command-mode: overrides eshell-exec-visual so TUI programs invoked from eshell (vim, htop, less, top) run in a dedicated ghostel buffer instead of the default term-mode fallback. Adds ghostel-exec as the public primitive for running an arbitrary program in a ghostel buffer and an eshell/ghostel builtin (8df9fc7).
ghostel-next-hyperlink / ghostel-previous-hyperlink navigate OSC 8 hyperlinks, auto-detected URLs, and file:line references via C-c C-n / C-c C-p; prompt navigation moves to C-c M-n / C-c M-p (895e55b).
ghostel-debug-info command collects Emacs version, system info, native module version (with mismatch warning), terminal state, and settings into *ghostel-debug* for pasting into bug reports. Resize and redraw events are now logged when ghostel-debug-start is active (b5d7b4d).
ghostel-ignore-cursor-change option ignores terminal requests that change cursor shape or visibility; useful when editor-owned cursor behaviour should take precedence (c901c02).
M-y with no preceding yank now opens a completing-read browser over the kill ring (works with consult/vertico) instead of signalling an error (e1e1896).

Changed

C-g is now sent to the terminal instead of triggering keyboard-quit; in copy mode it still exits copy mode (057fb1f).
Linkified file paths in terminal output now also match bare relative paths (e.g. src/foo.rs:43:4), paths wrapped in punctuation (Python tracebacks, backticks, brackets), and an optional :column after the line number. Configurable via ghostel-file-detection-regex. Closes #107 (ed17efb).
Module auto-download now works on systems that report amd64/arm64 in system-configuration (27dcec0).
OSC dispatch rewritten to scan each PTY write once instead of five times. A single OscIterator yields (code, payload, terminator) and one dispatchPostWriteOscs handles codes 7/51/52/133 in document order. Engine micro-benchmarks improve ~20–28% on bulk input (819098f, 1729f24).
CRLF normalisation is now zero-allocation and zero-copy. The old path allocated up to 131 KB of scratch (with heap fallback and a silent-truncation failure mode) and walked the input twice; the new path streams raw segments into libghostty's VT parser and emits \r\n inline at each bare \n. State is persisted across calls so a CRLF pair split between two writes isn't double-normalised (42092e7, 1729f24).
Module loader unified into a single helper. Load-time and interactive-command paths no longer diverge in guard checks, directory resolution, or failure mode (bbe1c41).
evil-ghostel now included in make checkdoc (0a9faa1).

Fixed

Top line no longer renders clipped after a terminal redraw when pixel-scroll-precision-mode had left a partial pixel offset. Closes #105 (bfb6e7c).
Scroll position preserved across window resizes (M-x, vertico open/close, window splits). A pre-redraw classifier tags windows as auto-follow vs. user-scrolled via multi-line content keys that survive scrollback eviction, full-redraw erase, and viewport rewrite — so scrolling up to read history and pressing M-x no longer yanks the view back to the prompt. Also eliminates a 1-row per-keystroke flicker seen in Claude Code's TUI. Closes #115 (2efecf2).
Backspace now works in terminal mode (emacs -nw). The event arrives as integer 127 and is now normalised to "backspace" at the Emacs-event boundary before key-name dispatch. Fixes #114 (c5b38d5).
Typing or pasting while point is in scrollback (after mouse wheel, M-v, pixel-scroll) now jumps the viewport to the terminal prompt as intended. Fixes #113 (31bdc9c).
Wheel events on an unselected ghostel window no longer hang Emacs. The scroll intercept was running in the selected window's buffer instead of the event window's, so the re-dispatched event hit the intercept again — infinite loop, recoverable only via C-g. Fixes #119 (305eacd).
ghostel-compile no longer leaves ~24 blank rows between the output and the footer on short commands. Trailing blank grid rows from the VT render are trimmed on finalise. Fixes #111 (60ab84f).
OSC iterator no longer cannibalises the next OSC's bytes when a preceding OSC is missing its terminator — a new \e] introducer now ends the current payload (1729f24).

Fixed
