| * GUI goldens settle on the window's idle, not two captures that agreeGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | test/gui_golden.py hashed a scene once two captures 400 ms apart agreed; on a loaded machine a slow frame agreed with itself before the scene's change landed and every later hash moved up a scene. A test window now writes a status file into its capture directory each loop step (gui.zig writeTestStatus: step, frames captured, idle — nothing owes a frame, nothing moves, nothing waits on the core's clock), and the harness waits for an idle step two past the one current when it asks: a 9P write has been served by then, so the frame is the scene's. Two things kept a window from ever going idle, both fixed: - Look-hover re-armed forever: resting on a word with nothing to open, the hover wait ran its two frames, found nothing, cancelled, and the next present's pointer refresh started it again: a frame every other frame for as long as the pointer rested there, live too (CPU). The place last refused is remembered (Pardes.look_hover_refused) until the pointer moves off it. - The virtual clock moved only on a wait that timed out, so a steady trickle of events held it still; it now moves to the core's wake too when an event cut the wait short and nothing owes a frame. Captures go to a directory of their own, outside the session's (a file written there every frame is a change in the directory its panes look at). All 17 goldens match the file as recorded at oooopqyv; eight runs, five alongside a ReleaseFast build and three with all 16 cores saturated (load 13-19), were byte-identical, 14 s a run unloaded (was ~30). Tests: the resting pointer lets the core go idle.
| * G12: Occlusion, pane bodies darkening faintly toward their edgesGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | Occlusion on|off (off, a pixel shell's; Chrome.fx bit 2 — the glow bits field is now `fx`): four soft strips cast from just outside each pane body inward, clipped to the body and round a cursor, black pre-warped to linear light, 2% at most (§9.1) and under the lift's contrast ceiling, in the pane's own group. Tests: the shade stays inside the body, off the cursor, at most 2%. Gates as G11. Feel review: .scratch/render/occlusion/ (with an x40 diff).
| * G11: HoverGlow, a soft underline of light under a look-hover's wordGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | HoverGlow on|off (off, a pixel shell's; Chrome.glows bit 1, SelectionGlow bit 0 now that there are two): under the word a look-hover would open (its cells in the affordance's tint) a strip three logical pixels tall along its foot, blurred by one, in the theme's accent, at most 22% and under the text's contrast floor, fading in over 80 ms; kept to the bodies and split round a cursor. glowBlocks serves G9 and G11. The strip is cast from a row away so addSoft's caster cut-out misses it. Tests: the glow comes up by 90 ms and never falls on the cursor's cell. Gates as G10 (a loaded machine shifted the GUI goldens a scene once; a rerun matched 01-08). Feel review: .scratch/render/hover/.
* | A refusal over unsaved panes keeps its list in +Unsaved and shows a short noticeGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | Exit's refusal (and Restore's, Del's, Delcol's, get's) put its full text on a notice that went: a long list of names, gone before it was read. The list now goes into one +Unsaved pane, filled again by each refusal, a row a pane (`<name>: Modified`) and the `Exit again to discard` line; the notice is short, `3 unsaved panes — Exit again to discard`. The 9P `unsaved` records and the write's err are as they were. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | ThemeSel is Themes and FontSel is Fonts; the old words still work in init ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | files and dumps The user asked for the plainer words. Every use is renamed: the builtins, leader paths, /commands, the docs and tutor, tests, and the themesel golden, re-recorded. An init file's ThemeSel or FontSel runs the new word and says `ThemeSel: renamed to Themes`, as ColumnTags is said; a dump naming an output pane by the old word restores it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | closed file reopens it A file closed by accident, its path forgotten, could not be found again: the jumplist dropped closed panes. Every file opened (a look, a Save of a scratch, a Restore, a rename) goes first in a list of 200, kept once, its dot noted when it closes, kept across sessions in $XDG_STATE_HOME/pardes/ recent. `Recent` (SPC f r) shows it in a reused +Recent, each row `path:line:col open|closed` a look reopens; /recent reads `open|closed <path>`. The jumplist keeps a closed file's entries, +Jumps marks them `(closed)`, and Back to one opens the file at its place. acme has no such thing; its dump and Load are the nearest.

* | A column takes panes until their minimums fill it, not until none can be halvedGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | Placement halved the tallest pane or refused, so 11 panes filled 48 rows that hold 16 at their tag and two rows each: the refusal did not match the documented arithmetic. When no pane can be halved but the minimums with the new pane's fit, the column's rows are shared out again; and a refused pane's removal leaves no pane under its minimum.

* | Find and Grep share one +Search a directory, each run replacing the lastGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | Each Grep with a new pattern opened another +Search, until the column refused panes. Find and Grep now reuse their directory's one, as acme reuses +Errors, and the exec reads back the pane it filled; a plain word's LookWord list search keeps a pane a pattern as before.

| | | | | | | | | | | | | | | | | | | | | | | | are ENOENT, a GUI-only setting EINVAL A Dump into a DumpDir not there failed EIO `file not found`; `no shell "x"` read as EIO through a mount; and a GUI-only setting on a terminal, EINVAL in the reply, had no word 9ns reads as EINVAL.

A line that ran says why in its own words everywhere now; only a line refused as no message at all quotes it, as Plan 9's cmderror does. Co-Authored-By: Claude Opus 5.5 <[email protected]>

* | A shell that cannot start fails Tty and pty/ctl exec with why, before either ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | answers A shell whose exec failed (a script's missing interpreter) was reported started: Tty and pty/ctl exec succeeded, then the pane died. The child now reports a failed chdir or exec through a close-on-exec pipe the parent reads before acknowledging the shell; the host's spawn fails with the reason (`shell not found`, ENOENT), which fails the waiting write. A Tty whose first shell never ran leaves no pane; a terminal restarted by pty/ctl exec keeps its pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | says so A NUL written into a tag went into the dump, which the host then could not write, and Dump said nothing: a success that wrote nothing. Tag writes, the workspace's, a column's and a pane's, refuse control characters but tab and newline, DEL, C1 and bytes not UTF-8, EINVAL; and Dump reports any failure of its own instead of swallowing it.

* | A served-tree pane spoils no Grep, and `look .` from a gone directory is ENOENTGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | A pane named `/virtual` gave Grep the root `/`, which swallowed every other pane's directory and ran out of walk before any file: every Grep missed. Grep passes over panes of the served tree. And `.` from a pane whose directory was gone resolved to the served tree's root (/virtual/), or through the jump list to another pane's directory: a dot path is the looking pane's own, and gone it fails, `look: <dir>: no such directory`.

| | | | | | | | | | | | | | | | | | | | | | words are Edit was let through the pane-word check (the root's ctl takes it at the active pane), so `Edit ,d` written to a tag no pane owns wiped the pane with the keyboard.

* | An err record's reason that names its file already is not prefixed twiceGabriel Schneider5 days
| | | | | | | | | | | | | | A refused look logged `err N look: look: no space for a pane...`: the reason began with the file's name, and the record put it before it again. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | name as \n /index printed a name as it was, so a directory with a newline in it split its row in two, and bytes not UTF-8 went through; the log turned the newline into a space, silently another name. Both now show a name one way: a newline `\n`, other controls, DEL and C1 a space, bytes not UTF-8 `\xNN`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* | Every EINVAL a write gets says why; DEL in an exec or look line is a control ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | character An empty name, a word written to log other than follow, a data, sel, dot or dirty write to a pane with no text, a truncate other than to zero, and a control character in a look line written through a held open were refused with no words, logged as `Invalid argument`. Each says its reason now; and DEL is refused in exec and look lines as in names. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | removed under a shell leaves its name `exec` on pty/ctl restarted a shell in a directory that was gone, the write succeeding and the pane dead; and the pane was then renamed `<dir> (deleted)` from /proc, so a restart failed even once the directory was back. `exec` is now refused up front, ENOENT, where the directory is gone; a shell the host cannot start fails the waiting write (late failure, as a Save's); and a `(deleted)` cwd is no name to take.

| | | | | | | | | | | | | | | | | | | | | | | | | | shell never started ends exit 127 Exec made a command pane in a directory that was not there, whose shell never started: it said running for ever, a follower waited for an exit that never came, and Kill found it. The line now fails up front, as Tty does, `exec: <dir>: no such directory`; and a command pane whose shell the host could not start ends `exit 127` at once. A shell that could not start in its directory says `directory missing`, not `file not found`. Co-Authored-By: Claude Opus 5.5 <[email protected]>

A shell given a directory is named by it already (newShell) and is no longer asked at fork; and until it has printed anything, an answer naming this process's directory is not taken.

| | | | | | | | | | | | | | | | | | A look at a directory, or an exec at a terminal, typed its line after whatever sat unsent at the prompt and ran the two joined (`echo TYPEDls`). A terminal with text at its prompt now takes no line; a look at its directory opens a new terminal, an exec runs as a command pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | miss fails Round 18 made a search that found nothing fail, but grep and find never counted their rows (only a pane search did), so every Grep read as a miss. Both count the lines they wrote now; a Find or Grep that finds nothing fails alike, `find: no match, not found` / `grep: ...`, ENOENT, and opens no empty +Search.

* | A builtin failure over something not there answers ENOENT: Unmount of a name ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | not mounted `Unmount nothere` failed EIO with `not mounted`. It says `no such mount nothere` now, and a builtin's failure that says `no such` (this, Tty's `no such directory`) answers ENOENT, the errno 9ns reads from those words.

| | | | | | | | | | | | | | | | | | | | | | The greeting waited for any moment the cursor sat at a prompt's input, so where the first prompt was missed (a resize still pending, a line written before it), `ls` was typed later into whatever ran then. It is now sent only while nothing has run (pardes's marks saw no command start) and nothing is typed at the prompt; past that it is dropped, never typed late. A prompt drawn again for a resize is still the first. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Tty now refuses a directory that is not there, `Tty: <dir>: no such directory`, before making a pane; and a terminal whose shell the host could not start (Pardes.shellFailed, from each host's spawn) answers any run with `error shell gone`.

| * G10: the theme's chrome fades through OKLab, easing in and outGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | ChromeTheme.interpolate mixes each colour in OKLab (colors.mixOklab), so a fade between hues keeps its lightness instead of going dark and muddy mid way; animation.Fade eases it in and out (smooth), and one retargeted mid fade eases out from where it shows, so it never stalls. Still 10 frames (160 ms). The page, text and syntax colours change at once as before. Tests: OKLab round-trips its ends exactly and keeps a red-to-green mid-way brighter than the sRGB mix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SelectionGlow on|off (off; a pixel shell's, Chrome.selection_glow): each block of selected rows in a pane body casts Lift's soft kind in the selection's own colour, the block its caster (never touched) and a cursor beside it joined to the caster; clipped to the bodies (never a tag or a grip); at most 22% (§8.2), less where the text round it would drop below min(its contrast, 4.5); fading in over 100 ms with an ease-out, on the core's continuous path (shell_continuous); none while panes move. Blocks come from the cells in the theme's selection colour (documented). Tests: the halo's colour, its clip to the body, nothing at its first frame and up to its cap after 100 ms, fading done. Gates as G8. Feel review: .scratch/render/selection/.
| * G8: a notice leaves quicker than it arrivesGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | The notice chip's motion was mostly there (a drop easing out on the Motion flavour, a dissolve easing in, Lift's shadow in tier 4 at its fade). Its dissolve took 300 ms against a 180 ms fall, the wrong way round for §8.1 (leaving quicker than arriving, 100 to 160 ms): MessageDissolve now defaults to 150. The field comments had the two easings swapped; the stack test pins a longer dissolve for the case it checks. docs/config.md and docs/effects.md say so. Tests: both timings in their bands, leaving quicker. Gates as G7 (no golden moved). Feel review: .scratch/render/notices/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dissolve crossfades - Track.launch: a move retargeted mid-way (Presentation.sync) starts at the old move's speed along the new one's longest side (carriedLaunch, Motion.easeFrom/speedFrom), so a second change during a slide bends the motion instead of stopping it dead. The macOS track ABI grows the float (pardes.h, 48 bytes; its reserved byte is named motion, as in Zig). - A pane that slides, zooms or rises casts Lift's soft shadow at sin(pi x progress) of its strength, on the other panes' bodies and rails alone, under the same contrast ceiling, carried by its track. - The GUI's PanelDissolve is a crossfade: the new cell drawn first, the old one over it at 1 - progress, premultiplied, on the blending cell pipeline for such groups (new cells now emitted before old ones, as the old layers already came after the new). sRGB blend, not linear light (documented). The tty keeps its per-cell swap. Presentation.zig's and animation.zig's tests were not in any test root; pardes.zig's test block now takes them in. Tests: a retargeted move carries its speed and still lands exactly; a moving pane's shadow is clipped off every tag, grip and its own body, none at the start or the landing, most mid-way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A mouse wheel's notch (SDL's whole-number step, notchOf) scrolls the core by its lines at once, so keys and clicks act where the text is, and the picture follows on the Motion flavour's spring at half again its pace, critically damped whatever the flavour (text never passes its mark), carried from its current speed (animation.Spring.carry), so notches in a row flow on. How far the rows moved is measured on the next frame against the last (Glide.measure: a wrapped line's rows, a terminal's output, with a couple of rows' slack for the cursor's line and its number); the rows that left are kept, nearest first, and drawn in the gap the lag opens; the lag is never more than the body's height. A touchpad's fractions move the picture under the finger as before; `Motion off` lands a notch at once; a PDF page scrolls as before. The glide runs on the core's continuous path: Pardes.shell_continuous keeps frames coming every loop while it moves and carries a virtual clock with it; idle, nothing. The test feed takes wheel events (ESC]777;mouse;wheel;<amount>;<x>;<y>BEL). Tests: notch vs fraction; a carried spring keeps its speed and never passes its mark; a notch over two-row lines lags two rows, keeps the rows that left, settles frame by frame and leaves the continuous path, and lands at once with Motion off.

| * G5: lapis, 0x4200.cafe's manuscript, as a theme with its ornamentGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A native theme `lapis` (src/themes/lapis.zig) from web/theme/lapis.css: a lapis-deep page, lapis tags with gold names, vellum text, vermilion rubrics, gold rules and a vermilion tag rule, gold selection in lapis ink. Its ornament is the theme's new `decor` (colors.Decor), drawn by a pixel shell inside the chrome it already has (decision 1), all of it off every focus indicator: - page_dots: the site's gold dot grid (#e8c46a22, 22 px), drawn by the cell shader on page-coloured cells alone (flag 0x10000000), so it lies under the text and never under a selection, a tag or the cursor; fixed to the window, a page the panes lie on. - rail_checker: the dither frame's gold and lapis checker in the scroll track (a decor kind, flag 0x08000000), anchored to its rail; the thumb stays solid gold. - tag plaques (tag_border, tag_shadow, tag_stripe): every tag a raised plaque inside its own band, the site's trail: a 2px gold frame and a hard 5px vermilion shadow down and right, both within the band's rows and columns (down, what the slack under the text leaves), so no shadow reaches a body, a grip or the next pane. The focused pane's plaque is the code window's title bar, gold and lapis stripes of 2px, its words on plates of the focused ground; unfocused ones are plain; column and workspace tags take the object-label language (1px frame, 2px shadow toward the page). Drawn as decor under the cells (a group's under range), with blank tag cells see-through and the cells blended premultiplied (pipeline_over) on such frames; opaque windows only. - title_shadow: the titles' vermilion offset shadow under a file name's letters, sampled in the cell shader inside the letters' own cells (flag 0x08000000), none on a cursor. Chrome carries the decor (decor_*, name_ink, active_name_ink); a theme file folds a nested decor literal field by field. Left out, with why, in docs/effects.md: the fonts, the ornaments, a decor crossfade, and in the tty anything but the colours (a tag row has no spare cell for a shadow). An empty column is the page. The effect id is masked to 27 bits (ui.vert/ui.frag) for the fifth flag. Tests: the cell flags land only on page ground and file-name cells, never a cursor, nothing without decor; lapis's plaques stay inside their tag's band, clear of every grip, only the focused one striped; its checker is in the track; no other theme draws any; the separator and focus tests cover lapis. Goldens: theme and themesel (the ring gains lapis after acme). Gates as G4.
