| | * Post chain: Shadertoy passes compiled by glslc; Crt, Ripple and Glitch ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rewritten as Shadertoy files Stage 9 of docs/render-pipeline.md. src/gui/Post.zig runs the chain over the finished frame: each pass reads the one before, ping-pong textures between, the last writes the window; an empty chain is the direct path. The prefix (shaders/post/prefix.glsl) is ghostty's uniform block, name for name and offset for offset (tested against a copy of its Uniforms, the selection colours by their GLSL names), at SDL GPU's bindings, y down. A user's file (Shader <path>) is compiled by glslc with compileGlsl's own flags on a thread of its own, taken in at the next loop step; errors name the file's own lines; a failed compile keeps the last good pipeline; glslc missing is said once. The bundled passes compile with the build, through the same prefix. Crt, Ripple and Glitch are Shadertoy files, rewritten: no barrel (input is identity, tested), everything in linear light and dithered, keyed to iTime. scene_effects, crt.zig and crt.frag.glsl are gone; the core keeps no clock for the chain. ShaderAnimation off|on|always drives redraw level A: the chain alone over the retained frame (34 us CPU a redraw, measured). Shared files touched: pardes.zig (nextWake loses the scene line, disableSceneEffects empties the chain, two tests), builtins.zig (one switch arm), ninep/ctl.zig (two switch arms), macos.zig (flags from the chain), gui.zig. Not touched: Messages.zig, mouse.zig, detached/*, host_io, tty.
| | * The GUI draws in tiers from the regions; pane chrome moves with its paneGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stage 8 of docs/render-pipeline.md. The frame is drawn in groups: tier 0, one per track in paint order (tiers 2 and 3), tier 4 (notices, then guides and the debug box), tier 5 (bar cursors), each cells, images, decor. Decor (rules, rails, thumbs, grip marks, spines, the workspace and column rules, the bottom band, notice rules, bar cursors) is whole-pixel rects through the new decor.frag over ui.vert, so it carries its track's transition and clip. A closing pane's chrome comes from Surface.previous_regions. Deleted: taglineBaseRgb, topbarPaneBorderHeight, bottomTaglinePresent, frameChromeBg, cellBackgroundIs and the rail inference, paneGripCell's scan, transient_on, PaintPlan. One cover map (coverFrame) is marked from the layers and regions once a frame. New regions column, guide and debug; Surface.chrome is the palette, carried in wire v8 (not shipped yet), so an attached GUI draws the same chrome (test). A per-instance clip replaces the vertical transition's scissor. Goldens: 01-12 byte-identical. 13-17 differ only past the grid: the image pass left its scissor at the grid's size, cutting rule ends, rail feet and the bottom band in the leftover pixels whenever a picture was on screen. 16-debug now shows the debug box, which a context-row layer had hidden. 18-mid-transition is new: virtual clock (PARDES_TEST_CLOCK in the GUI), PanelSlide Newcol with the picture, frame 6 of 12. Also: the GUI sleeps when idle instead of polling every 16 ms, and a minimized or occluded window sleeps through animation. Tracy 'gui frame build' at 200x60: 992/1015 us median before, 989/987 us after. Shared files touched: pardes.zig (one export), detached/client.zig, detached/server.zig, detached/wire.zig (all additive), gui.zig. Not touched: Messages.zig, mouse.zig, tagline.zig, colors.zig, tty.zig, host_io.zig, dump.zig, exec.zig, panes.zig.
| | * One Layer for tags, notices, headers and bodies; a taller tag is one layer ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of rows; wire v8 src/Layer.zig merges TagLayer and BodyLayer. `rows` (0 = no layer) and a cursor at {x, y}. A tag of N rows is ONE layer of N grid rows: tagHit answers the row as `line`, bodyHit keeps its meaning, and the per-line layer bases (TAG_LINE_LAYER_BASE, HEADER_LINE_LAYER_BASE) are gone, not aliased. Wire v8, the one bump: tag layers carry rows and cursor y, and the frame carries the placed region list. v7 and v9 peers are refused in both directions (server test over both, a new frontend test over both). web: tag_layer_value 11 = rows, 12 = cursor y; app.mjs lays every row. macOS: the Zig side compiles against Layer; pardes.h still sees one row per tag layer (accepted, the macOS shell is ignored for now). No visual change: snapshot goldens and the 17 GUI goldens byte-identical. Shared files touched: pardes.zig, Messages.zig, gui.zig, macos.zig, detached/client.zig, detached/server.zig, detached/wire.zig (plus web.zig, app.mjs, edit.zig, look.zig). Not touched: mouse.zig, tagline.zig, colors.zig, tty.zig, dump.zig, exec.zig, host_io.zig, panes.zig.
| | * Place every part of the frame once, before painting itGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | draw.place builds the Surface's region list at the head of render: the page; each pane's grip, tag rows, body, rail with its thumb, and notice chips; each column's grip and tag; the workspace tag. The painters read their geometry from it instead of working it out again: the grid's notice chips and the notice layers share one chip rectangle, the rails (file, terminal, image, PDF page) paint the placed thumb (a native PDF measures its own into the region as it places its pages), and the body, tag, notice and column layers take their viewports from their regions. A collapsed pane places only its grip and tag. The column-move rail's one-cell clip of the layers under it is now a region field set in place, not a mutation of the built layers. No behaviour change; a test checks every region against the old geometry, the painted rail and the layer viewports across tag bottom, column tags, notices, a collapsed pane and a multi-line tag.
| | * Step core animation by the shell's clock and sleep to the next wakeGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A shell now answers Host.now, its monotonic clock in ns, and the pump advances core animation to it: one .tick per whole 16 ms frame since core time last stood still. The same animation therefore takes the same time at 60, 120 and 144 Hz, over ssh and after a slow frame (the GUI's re-armed clock ran them ~25% slow at 144 Hz; the tty's post-frame sleep drifted). nextWake() lists every core animation in one place: a frame from now while anything moves, the end of the wait while something only waits (a message lingering, the look-hover delay), null when idle. Shells sleep exactly that long, and a wait is jumped to its end in one step, so an 800 ms linger costs one frame instead of fifty. An overshoot under 1.5 ms after a step is let go: at 60 and 120 Hz every display frame takes exactly one step (a 16 ms frame against a 16.67 ms vsync would otherwise double-step every 24th). The six tick drivers are gone: tty's timer thread only times the wait, interruptibly (a newer, shorter request cuts short a sleep still timing a longer one); the GUI's AnimationClock, web's JS tick bank (pardes_tick now takes rAF's timestamp), the detached server's and the board's ticks; grid mode steps a virtual clock straight to each wake. PARDES_TEST_CLOCK, set by the snapshot harness, gives tty and the detached server the same virtual clock. Every stepped frame is drawn. The old pump never drew the last frame of a fade (a .tick asks for no frame, and the fade was over by the check), so a theme switch stopped at 9/10 of the way until the next input: theme.golden, themesel.golden and the GUI's acme-light scene move to the theme's true colours, and nothing else changes. The frozen previous grid is captured only while a panel transition is chosen, not on every idle frame.
| | * Move the frame into draw.zig and the transitions out of layout.zigGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pure moves, no behaviour change. draw.zig holds the whole core frame in order: render, the pane, tag, header and notice painters it calls, and the character-effect composition (Pardes.render stays a declaration alias). Presentation.zig is the panel presentation state as a file struct, and animation.zig the easing curves, transition kinds, tracks and boxes, the character effects' sources and the generic displayed-value transition, all of which lived in layout.zig. layout.zig keeps only layout.
| * | A selection's other ranges live out of line, made at the second range and ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | freed at one The ranges beside the primary were an inline array in every Text, which at 1024 grew each pane by about 60 KiB. They are now allocated when a second range appears (Text.reserveSels) and given back when the selection is one range again (Text.dropSels); a column's or the workspace's tag allocates from Text.gpa, any other text from its pane's. A refused tag edit restores them by copy. The Pane size budget is back to 128 KiB, and a test holds that a single cursor allocates nothing for them.

| * | gw labels the words in view and jumps to the one whose label is typedGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | helix goto_word: the words of two or more word characters between the view's first and last lines get two-letter labels, nearest the cursor first, one forward and one back in turn (modal.jumpWords). The next two keys choose one and select it, stretching the selection to it in select mode; any other key takes the labels away. The words live on Pane.jump, and renderBody paints their labels over the body's cells in the selection colours, the one change on the render side. Co-Authored-By: Claude Opus 5.5 <[email protected]>
| * | K and Alt-K keep or drop the ranges a regex matches in; Alt-: turns every ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | range forward K and Alt-K share the s/S prompt, which now carries a mode rather than a split flag: a range stays when a match starts inside it (K) or when none does (Alt-K), the primary becomes the first, and keeping none leaves the selection as it was (helix keep_or_remove_matches). Alt-: is ensure_selections_forward. Co-Authored-By: Claude Opus 5.5 <[email protected]>
| * | A selection holds up to 1024 ranges on the desktop, 64 on the boardGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The limit was 64 everywhere, which helix-golf's enumerate_and_align outgrows (%s |\d+ makes 121 ranges). It is now memory.limits.selections, per platform, and the counts that hold it are u16. The ranges stay inline in each Text, so a pane grows by about 80 KiB on the desktop (three texts and the regex prompt's snapshot); the Pane size budget in Terminal.zig moves from 128 to 160 KiB and says why.

| * | Q records keys into a register and q types them again; . repeats the last insertGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Macro.zig keeps keys to be typed again. Q records into @ (or "<reg>) in helix's key notation until the next Q; q replays a register's keys count times through the modal handling, where Esc does not hop panes and Enter, Tab and Space neither look, execute nor open the leader. . replays the normal command that entered the last insert session once and what was typed in it count times (helix repeat_last_insert). a at the end of the text now adds the newline helix's append_mode does, which a terminal's text does not. helix-golf's invert_dictionary passes.

| * | A tag's edited text stays alive until the next edit, so ms and md in a tag ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read it whole setEditText freed the text a tag edit was handed once it had copied the tag's own part out of it, but every caller reads that text back to place the cursor, and surround goes on to edit it again: ms and md in a tag read freed memory. The same held for a terminal without an edit buffer and a text with no pane. The text is now kept until the next such edit (edit.retireEditText), which covers every caller at once; the callers the audit found reading it back are surround's two, the paste and replace paths, the number adjust, and the insert-mode Enter.

| * | Registers hold a value per range, and "<reg> names oneGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Registers.zig replaces the one yank buffer: every register keeps a value per range, y fills them in document order, and p, P, R and insert Ctrl-r put value i at range i, repeating the last (helix paste_impl). "<reg> names the register for the next command; _ swallows, # numbers the ranges, . is each range's text, % the file's name, / the last s/S pattern, and + and * are the system clipboard through the ClipYank and ClipPaste paths. SPC y now writes + alone, as helix's does. The acme chords and a paste into a terminal take the default register joined by newlines. The msel-yank-paste waiver is gone.

* | | A REPL question's answer goes to the pane its letter offered, or says that ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | one is gone The letter was looked up again when answered, so a REPL closed or rebound while the question stood could hand the text to another pane with the same letter, or drop it without a word. The question now keeps each letter's serial; the answer is that pane, still bound and running, or a message. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | | Errors are said in words, and a refusal names what it takesGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | A failure read `Del k|j: InvalidArgument`, `Kill: NoSuchCommand`, `ill-formed control message`, or nothing at all. reportError now spells an error's name as words, and the refusals name their accepted forms: pty/ctl lists its verbs, a flag file takes 1 or 0, a setting word takes on or off, Del takes k, j or nothing, Repl takes - or a language. Kill with nothing to stop says so, /focus says pane, a Look that found nothing says no match, and pty/run on a command pane says it is not a shell. A ctl write's failure has room for the Repl list and is cut between words, the Repl word at a character. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | | A REPL's language is named and found as the syntax table finds one: aliases, ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | any case Repl took only the grammar's exact name, and a file's language was found by a case-sensitive suffix of its path, apart from the aliases a code fence already had. The aliases move to grammar_manifest with byName and byPath, which syntax, Repl and langOf share, so `Repl py` and a .PY file work. The line-by-line warning is for the python language, not an id that starts with python. Joincol's doc line was sitting on Repl. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | | Focus on a closed pane goes to the pane that takes its place, never to the ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | one focused before Dogfood closed a pane in one column and focus jumped to another column, only because that pane was focused last. Now removePane decides for every route (Del, a ctl del, a command pane's end, a 9P remove, a stillborn scratch replaced): the pane that grew into the rows, or the scratch standing in an emptied column; removeColumn gives it to the pane level with it in the column that takes the width. Closing an unfocused pane leaves focus alone. The per-caller focus lines in Del and replaceStillborn are gone, and so is prevFocus. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | | Text sent to a REPL is plain lines, sent whole or not at allGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A CRLF became two line ends, the blank line ending a Python block; an ESC in the text, ESC[201~ above all, could end a bracketed paste early; and on the board, whose writes are 128 effects of 64 bytes with nothing pending, a send past 8 KB was cut and lost its closing ESC[201~ and Enter, leaving the REPL in a paste. Lines now end in LF alone, ESC and every control byte but tab and newline are dropped, and a send larger than can be written at once (Pardes.writeRoom) is refused with a message instead of cut.

* | | A command's exit is told once its output is in, by the pty's state, not a timerGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The watcher woke the host a second time 60 ms after the exit by its own clock while the grace was counted from the reap: a host busy for 10 ms missed it, and the tag said running for ever and Kill did nothing; and under load exit 0 could land before the last output. As decided, no timer: the exit is told once it is reaped and the pty says nothing is left (poll: no POLLIN, and no POLLHUP, which means the end of file is on its way behind the output), else at that end of file, checked after each chunk of output. The tty host checks inside its step so the frame shows it. The four hosts' copies are one host_io.takeExits/commandEof, which close a told command's pty at its end of file (the fd and the GUI's reader leaked when the exit came first). A finished command pane whose pty a job it left still holds is not reused, so that job is not hung up; and the reset before a reuse is SGR 0, not DECSTR, which ghostty's stream does not implement.

* | | A click written back to event is done as the click, REPL and all; a REPL's ↵Gabriel Schneider3 days

An F record, a line written to exec, was never a click and still runs as a command. For a readable list of bindings, the smallest place: a bound terminal's ctl line ends with its id after current/notcurrent. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the REPL The execute key and the middle click marked a global flag that the first execute cleared, so of several selections executed at once only the first reached a bound REPL and the rest ran as commands. Where an exec came from now goes with it, as acme's execute() asks of its Text (exec.c:122,169): builtins.Ctx carries from_body, runBuiltinFrom and executeFrom take it, the gestures set it, and chordEachSel sets it for each selection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | before it is answered A pane that joins a column holding only an empty +New takes the column, but that replacement ran at the end of the editor's next update, not of a 9P request: a look answered 19 while index still listed the +New 18, whose del came later. serveFs, a step of its own, now runs it too before answering.

* | | A restored terminal's tag names neither the REPL it was nor the shell it hadGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A dump keeps a terminal's whole tag, and restoring read its tail from it after the directory: the REPL id and Tty+fish, which were live facts and not the tag's text, came back as a custom tail, so the tags said python-a over a fresh shell bound to nothing. Restoring now sees through the id and the shell in the Tty word, a default tail stays the default, and the new shell names itself when it starts. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | | A REPL takes text only while its program has the terminalGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A binding outlived its program: a command pane reused kept the REPL of the command before, a done command pane could be bound, a document pane (a terminal with no emulator) was accepted, and after Ctrl-D in python3 the text went to the shell, which ran import os as ImageMagick's. A command pane's binding now ends with its command and a done one is refused, a pane with no emulator is refused, and an interactive terminal's REPL is live only while a program other than its shell holds the tty (the host's tty_taken); when none of the language's REPLs is, nothing is sent or run and the pane says so.

* | | Tty with a shell that is not there says so, and never sets the caller's shellGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tty /nonexistent or Tty fsh started the host's fallback shell without a word, and when spawnTty made no pane, the argument became the calling pane's shell. Tty now looks the shell up first and fails 'Tty: no shell "fsh"' when it is neither a name on the usual paths nor a path to one; spawnTty answers the pane it made, the one given the shell, and says why when it made none. The lookup (host_io Shell.find) gives the turn up around its access() calls, since a typed path may be under a mount this editor serves, and forkShell copies the pane's shell before looking it up and checks the pane is still its own after.

* | | A command pane echoes its first command as it does the later onesGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | Only a reused pane showed '% line' above its command, so the first command's output stood with nothing saying what made it.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | never panics on a longer prefix A two-line exec made a command pane whose tag prefix held the line's newline, so the tag ran to a second row and tagTintRange sliced its first row past its end: panic. acme runs a multi-line selection as one command, and so does pardes; the tag now shows the line's first row, cut at a character's start, and '...', tagTintRange stays inside the row it is given, and the '% line' echo turns the line's newlines into the terminal's, so it does not staircase.

* | A terminal bound as a language's REPL takes the execs made on that ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | language's files Repl python in a terminal's tag or on its ctl binds it (Repl - unbinds, Repl bare says the binding, the same word again changes nothing), with an id, python-a, python-b, in its tag. An exec made by a gesture on the body of a file in that language -- a middle click or the execute key, on any text, a single word too -- or on the REPL's own body is typed into it, bracketed if its program asked for that, else line by line with a once-said warning for Python's blank lines, then Enter; the message row says -> python-a in the tag's name tint, the log send <from> <to> <id>. Several bound for the language: the pane asks which on its notice band, as Del asks, one key answering, Esc none, nothing remembered. The gesture is known where it is dispatched (mouse.zig, the execute key), so the tag's words, Exec <text> run by name and a command word @`cmd` stay commands, and a 9P exec is never sent. A finished command pane is no REPL; bindings are not dumped. The docs spell out the escapes, the pdb and input() caveat and the no-bracketed-paste papercut.

* | Kill signals a command only while it runs, and only the pane it was meant forGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | A signal effect carried only a slot, so a Kill followed in the same step by the pane's closing and its slot's reuse signalled the new pane's child; and a command pane whose child had exited and been reaped kept a process group id another process could take. The effect now carries the pane's serial, checked as it is performed, and a host signals no command whose exit it has recorded; the core already sends Kill only to a command it has not been told is done.

* | A command pane's command is over when its process exits, not when its pty closesGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A job left in the background (sleep 100 &) held the pty open, so the pane stayed running and the child a zombie until the job ended; a command that closed its terminal and ran on got its end of file at once, the host waited 100 ms for an exit, reported exit ? and hung it up. Now each command's child is watched on a thread (waitid with WNOWAIT, so its pid stays its own until the host reaps it), and the host tells the core the exit from that: after the pty's end of file, so the output before the exit is in, or 50 ms after the exit without one, a job holding the pty. The pty stays open until both, so a command that let go of its terminal is never hung up by it. All four front ends; a host that cannot start the watcher reads the exit at end of file as before.

| | | | | | | | | | | | | | | | | | | | | | | | | | command A program that crashed out of a full screen left the command pane's emulator in the alternate screen with mouse reports, bracketed paste or a hidden cursor on, and the next command ran in that. Before the '% line' separator the pane now leaves the alternate screen, turns those modes off and soft-resets (DECSTR). The docs add that a command which clears the screen and its scrollback erases the pane's history above it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | Only Tty reads Word+arg as its argumentGabriel Schneider3 days
| | | | | | | | | | | | | | | | Every builtin that takes an argument split a word at its first +, so Dump+2024.zon ran Dump with 2024.zon. A builtin now opts in with plus_arg, read by the registry, and only Tty does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | A spawn names the pane it was made for, so a pane closed and its slot ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | retaken spawns nothing The spawn effect carried only a slot, and the host read the command and shell off whatever pane held the slot as it forked: a command pane closed and its slot taken by the next one before the effects ran forked the new pane's command twice. The effect now carries the pane's serial and is dropped when the slot holds another; forkShell checks it again after giving up the turn for its directory's stat, the one moment a 9P client can change the panes under it. Every front end performs spawns with the turn, from its step. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | A terminal's Tty word names its shell, Tty+fish, and a click on it opens anotherGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A terminal's tag said Tty whatever shell it ran. The host's acknowledgement of the shell it forked now sets the word to Tty+<shell>, tinted like the tag's name. Word+arg is taken as Word arg, one word a tag can hold and a click can take whole (+ is a word character), so Tty+fish opens a terminal on fish, as Tty fish does; Tty takes the shell as its argument, which the host forks for that pane instead of the configured one. Every snapshot whose screen shows a terminal's tag changes: 69 goldens, re-recorded by name, whose 297 changed lines are all Tty becoming Tty+bash (the harness runs bash), the cursor columns and style spans that moved with it, or that text cut at a pane's width.

* | A command line runs as its own command pane unless it is clicked at a ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | shell's prompt A middle click, an exec write or a tag word that no builtin knows was typed into some terminal for the pane's directory, sharing whatever state that shell was in and answering nothing, so a misspelling vanished into a shell. Now only a line clicked at an interactive terminal's prompt is typed there. From anywhere else it runs as a command pane: a terminal whose child is $SHELL -c the line in the pane's directory, full emulation, which shows its output and then exit N from the host's reaping of the child, and stays. A finished command pane is the next command's for its directory, which runs below what it showed after a '% line' line (acme appends to +Errors and never clears it, util.c:213); a running one gets a second pane. Kill ends a command pane's whole process group, the log records run and exit, exec reads back the command pane's serial, and a line is at most 1 KB, read off the pane as the host forks rather than carried in every spawn effect. ttyForDir's search for a free shell is gone. The goldens of chordcut, cmdword and layout-open change where a file's exec now opens a command pane, and ttytaken is rewritten to exec from the terminal itself; docs/open-questions.md records the decision.

* | Unattended messages expire in the detached session's loop, not as a 9P ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | request is served serveFs expired them, but a read is answered while a step is out in a syscall, because reads change nothing, and this one changed pane messages and needs_frame from under the step. The detached session's loop now expires them between steps, and while nobody is attached and a message is up it looks again every 100 ms rather than waiting for something to wake it.

* | With no frontend attached, a detached session's messages go after MessageLingerGabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | | | | | A message lingers until input dismisses it, and a detached session with nobody attached has no input: its messages, and /screen, kept what was said long ago. The session now marks the core unattended while no client is attached, and the core drops a pane's messages once the newest has been up MessageLinger on the clock, checked as it is stepped or served. A pane's older lines go with its newest rather than each on its own clock; the render pipeline's clock is the place for that. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | A Restore answers its writer before hanging up, and the log records dumps ↵Gabriel Schneider3 days
|/ | | | | | | | | | | | | | | | and restores A client that wrote Restore saw its connection cut with no answer, and could not tell a Restore from a crash. The listener now lets the writer's answer out before the cut, and cuts only the old editor's connections, refusing their requests meanwhile; a client that dials during it is the new editor's and stays. Dump logs 'dump <path>' and the restored editor's log 'restore <path>'. Keeping connections across a Restore was weighed and left: the fids name the old editor's panes and opens, so it would mean carrying serials and open records into the new one, where acme's Load only adds windows. tty's Restore also closed its shells' ptys without reaping them; it retires them now.

* Kill asks the host to signal at once and says when a shell has no job to signalGabriel Schneider3 days
| | | | | | | | | | | Kill queued a signal effect for later, so the job it saw running by its marks could have ended, and another started, before the signal went; and with job control off the job shares the shell's process group, so the host skipped it and Kill reported nothing. Kill now calls the host's kill_job while it holds the turn, and when the only job is the shell's own group says 'Kill: no job to signal', which also fails a write of Kill to ctl.

* A closed terminal's shell is reaped on tty and macOS, killed if it ignores ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | the hangup tty and macOS hung the pty up and called waitpid once without waiting, so a shell still exiting, or one that ignores SIGHUP, stayed a zombie or ran on with nobody reading it; tty also never reaped a shell that exited by itself, and its spawn into an occupied slot closed the old pty without ending the shell. host_io's retireShell says hangup, waits 100 ms on a thread (macOS has no host timer to poll from), then kills and reaps. The gui's own retired list, when full, left the slot holding the old shell and refused the next spawn into that pane; it now hands that shell to retireShell instead.

* Exit quits and Kill stops commands, as in acmeGabriel Schneider3 days
| | | | | | | | | | | | | | | | Kill quit the editor, which in acme is Exit; acme's Kill stops the commands it started. Exit now quits as acme's does (exec.c, rowclean): it refuses once, naming each pane with unsaved text, and quits when asked again with nothing edited since (a small scratch is not asked about). Kill, bare or with names, stops the commands pardes typed into a terminal (an exec, a middle click, a pty/run) while their shell's marks say they run, by SIGTERM to the terminal's foreground job, never to the shell (acme posts the kill note, which terminates). Both are session builtins; the topbar's Kill becomes Exit, same width, and every golden's topbar row changed by exactly that word (checked line by line); the builtins script scrolls one more row for the index's new line.

* Normal mode's s and S search as addr does, through one shared regexp.zigGabriel Schneider3 days
| | | | | | | | | | | | The sam-style calling convention for mvzr (a line per haystack, . made [^\\n] only when a pattern names \\n) lived in addr.zig; normal mode's s and S called mvzr over the raw selection, where ^ meant the selection's start and . crossed lines. src/regexp.zig now holds the one Regex (compile, find) both call, and fs.zig and pardes.zig drop an unused mvzr import. hxdiff and hxparity stay at their known 17 and 6 mismatches, none of them regex cases.

* A refused or failed write is an err record in the log, naming the file and ↵Gabriel Schneider3 days
| | | | | | | | | | | | the reason Through a mount every refusal reads as Invalid argument, so a shell user could not tell a missing regexp match from a bad ctl word. Every write or truncation the tree refuses or that fails now adds err <serial|-> <file>: <why> to /log. No per-pane readable error file: acme's errors only takes text, and one stream is simpler to watch. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A terminal's new directory is a rename in the log, and its ctl counts its bodyGabriel Schneider3 days
| | | | | | | | | | The log said new N / and later del N <cwd> for a terminal, with no rename in between, though a terminal is named by its directory. setCwd now logs the rename once the pane has been announced. A terminal's ctl line gave body length 0 while its body reads its history; it now counts that history (without keeping a copy). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pty/run on a fresh terminal waits for the shell's first prompt instead of ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | answering busy A new terminal's shell takes tens of milliseconds to draw its first prompt, and a run written meanwhile answered busy, so a script's first command was lost, while pty/status said busy 0. A line written before the first prompt now waits for it and is sent then (a respawn in between keeps it waiting for the new shell), and pty/status's third field says what a run would be told: busy while a command runs or text is typed at the prompt, not before the first prompt.

* A terminal pane that closes takes its shell and pty with it, in every front endGabriel Schneider3 days
| | | | | | | | | | | | | The detached server closed a pane's pty only when the shell was respawned, hit EOF or the session shut down, so rmdir, Del or Delcol on a terminal left its shell running with nobody to read it; the tty front end and macOS did the same. Retiring a terminal pane now emits a close_pty effect, which each host that runs shells answers by hanging the pty up and ending the shell (the detached server's and the GUI's existing retire-and-reap path, and a close plus SIGHUP in the tty and macOS shells).

* Split control messages by scope: the root ctl takes the session's builtins ↵Gabriel Schneider3 days
| | | | | | | | | | | | | | | | | | | | and reads the settings, a pane's ctl its own Every builtin could only be clicked, or written to exec, and the settings could be read only as the Config window's prose. acme keeps window verbs on a window's ctl, and webfs and upas/fs keep session settings on a root ctl. Each builtin now declares its scope (scope = .session; settings are all session, the rest pane), read by the registry. The root /ctl takes session builtins and reads every setting in the words a write takes, so its read written back changes nothing (panel and scene effects now take on/off like the toggles, to make that true); a pane's ctl takes the pane's builtins beside get, lock and unlock. Writes are checked whole and refused in Plan 9's ctl words (unknown control message "X", wrong #args ...), which 9ns now maps to EINVAL (cloud9 re-pinned at a8c7a715). A builtin that would prompt for its argument fails the write instead, and a refusal is answered at once, not after the frame. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Let the keyboard reach a tag's path, read-onlyGabriel Schneider3 days
| | | | | | | | | | | | | | The tag's computed path, dirty marker and page were out of the keyboard's reach: its cursor lived in the text after them. It now lives in the tag as shown, as in acme where the name is ordinary text at the start of the tag, so `0` goes to the line's start and motions select and yank the path. The path stays read-only: an edit that would change it is refused and leaves the cursor where it was, and typing into a file's path drafts a new name as a click on it does. Sync moves the tag's positions when the prefix changes length, so a rename or the dirty marker still never moves the cursor off the text after it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
