* clipboard, n/N and the tty prompt: three things that were half-wiredGabriel Schneider2026-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Three changes that all turned out to be the same shape -- a feature that worked in one direction, or for one pane kind, and quietly did not in the others. CLIPBOARD. Every register write emitted set_clipboard, so deleting one character threw away whatever the desktop was holding; multi-cursor yank took the join's early return and emitted nothing at all, so the same key reached the clipboard on one cursor and not on two. Nothing could READ the clipboard: the SDL shell had no SDL_GetClipboardText anywhere in it, and the tty shell never asked for OSC 52, so `p` from another application was dead in both. Now it is helix's split. y/d/c/p/P/R and the acme chords are the DEFAULT REGISTER and nothing else; the system clipboard is five words on helix's own letters -- SPC y, SPC Y, SPC p, SPC P, SPC R -- spelled as builtins so they land in Help and are executable like every other verb. The one exception is the tag `y` chord, which still mirrors out because a tag is always insert, so SPC cannot be pressed there, and copying the path out is the whole point of the chord. Reading is a new read_clipboard effect answered by an ordinary Event.paste, so the round trip is honest about being one: SDL and NSPasteboard answer inside the same drain, the browser answers a promise, and a terminal answers over OSC 52 or -- far more often -- refuses. A refused read is a paste that does not happen, and the request dies at the next keystroke rather than landing minutes late in whatever pane is focused by then. The tty shell also enables BRACKETED PASTE now and coalesces paste_start..paste_end into one event. Before this a paste arrived as a flood of individual key presses: plausible in insert mode, and in normal mode every pasted character ran as a command. n/N. They stepped the armed results buffer and immediately Looked each row, so you could not walk past a hit without opening it. They are a MOTION now: select the next look-able text, open nothing, and let Enter decide. What they step is the largest whitespace-delimited run look.resolve can act on (look.lookableSpan, wrapper punctuation peeled), over a RING of panes -- every pane that has performed a look, most recent first, then the output buffers that have not, newest first, and only if both are empty the pane in front of you. N is the exact inverse of n, computed rather than remembered: both directions ask the same question about the same spans and compare against the column the walk parks on, so x presses one way and x back land exactly where you started, pane boundaries and the ring's seam included. A ring rather than a list with two ends because a shell's cursor sits at the prompt, below everything it has printed, so a walk that could not come round would have nowhere to go on the very first press -- which is the case n/N were written for. One motion everywhere, no pane-kind or buffer-kind special case. The only thing a buffer may change is the GRAIN of what a step selects, and it does it with one flag rather than a branch: output_pane.Traits.commands (renamed from `executes`, which named one reader's behaviour rather than the fact) makes a row select WHOLE, because a ThemeSel line is a word to run and has no path inside it to pick out. `]d`/`[d` are not n/N -- they are helix's diagnostic motions, their job is to ARRIVE, and they still reach searchStep. THE TTY PROMPT. Leaving raw tty blanked the prompt row, and the command you had typed at that prompt shares the row, so it went too -- a shell out of tty read as output only. OSC 133 marks the row CELL by cell, so the two are separable: config.tty_blank = .prompt cuts the prompt's own columns and leaves the command, left-hugged at column 0 in line with the output under it rather than in a bay of blanks. .prompt_and_input is the old behaviour, kept. Because the row is now something you can put a cursor in, enterTty adds the hidden prompt width back before asking ghostty to walk the shell's own cursor to it -- the modal column on a cut row is short by exactly that much. Verified: unit-test 186/186 (nine new), snap 87/87 (new ttyprompt.snap), hxdiff 481 and hxparity 561 with 0 mismatches, tty and gui both build. And against the real binaries rather than the harness: in a pty, SPC y emits OSC 52 carrying exactly the selection while plain y emits nothing, SPC p issues the read and pastes the reply, and a bracketed paste of "dd..." inserts text instead of deleting two lines. In a real SDL window, SPC y then SPC p round trips through the system clipboard while the default register holds different text. Setting tty_blank back to .prompt_and_input reproduces all 86 old goldens byte for byte.
* macos: pixel attachments, live theming, and a signed appGabriel Schneider2026-08-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AppKit shell now draws what the core renders, follows the theme without a relaunch, and builds into something you can hand to someone. - Pixel attachments. Surface.images was dropped on the floor here, so a PDF pane showed nothing at all: native_images is now set, pardes_image_s carries the geometry the core already clipped, and PardesView keeps one CGImage per (serial, page, revision) so scrolling costs a draw and not a decode. Image panes get real pixels instead of the petscii fallback. - Themes take hold live. pardes_tick never advanced the chrome animation, so every tagline kept the previous theme's colours until the next launch and the 16 ms re-pump spun for the rest of the session. pardes_theme_bg retires the hand-agreed #121212 and drives the window background and the titlebar appearance; a theme with no background of its own now gets a transparent window over an NSVisualEffectView. - The cell snaps to whole DEVICE pixels rather than whole points. Monaco advances 8.4014pt at 14, so ceiling to 9 spaced every column 7.1% wider than the face was drawn for. - The dial is one notch per 10 degrees instead of 20, and a release keeps turning in proportion to how hard it was thrown -- ramping up from zero at the floor, so a slow twist coasts not a little but not at all. - A file dropped on the grid is a click plus Look, so it opens beside the pane it was dropped on. No drop concept was added to the core. - The titlebar follows the focused pane: proxy icon, filename, and the dirty dot. File.saved_revision is the watermark that last one needed. - Config (SPC f c) prints the resolved startup config path. - build.zig assembles, signs and packages the bundle itself; build-app.sh is gone. -Dmacos-identity= takes a Developer ID, macos-dmg makes the image, and the icon is Glenda.

* Help lists every builtin and every way to reach itGabriel Schneider2026-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Not a second builtin: Help already rendered "every builtin with a leader path and the key that runs it", and the ask is "every builtin and every shortcut" — the same listing with three more rows and one more column. A new builtin would have been a second renderer over a superset of the same rows, and the two would drift the first time a column moved. The prefix filter is now the degenerate case of the index rather than a separate mode: SPC h ? reads the same array with prefix "h", and the path-less builtins fall out on their own because an empty path starts with nothing. The shortcut column is folded, never typed: chordName spells a chord from Key's OWN declarations, so a new special key names itself and an unnamed non-printable codepoint is a compile error instead of garbage; shortcuts() walks the cmd columns of window_keys and jump_keys, look_cmd/exec_cmd with their keys and buttons, and topbar_str. Retarget a binding in config.zig and this re-renders. So Look reads `enter, right-click`, Back reads `C-o`, Kill reads `topbar`, and Theme reads nothing at all — which is the information. Not a picker, deliberately: n/N stepping a list holding Kill, Del and Delcol would end the session. The names are live text, so middle-click the one you want. Alt-n, Alt-c, the tty toggle and the cut/paste chords cannot appear — they are inline handlers that reach no builtin, so there is no row to put them on. Make one a struct with a cmd column beside its binding and it appears for free. Three goldens moved, all of them the +Help buffer's contents.
* themes: one file each, generated from helix and zed, picked by stepping a listGabriel Schneider2026-08-01
| | | | | | | | | | | | | | | | | | | | | | | | | Each theme is a .zig file of pure data and nothing enumerates them by hand — fold() walks the container's declarations, so a theme is a file and that is the whole registration. Field by field rather than a wholesale coercion, which makes a missing field a compile error that names it. tools/gen_themes.zig reads helix .toml and zed .json out of vendor/themes and emits one .zig each; build.zig reads that directory, so adding a theme is dropping a file in. Output goes to the build cache rather than the tree, so zig owns the freshness check and a deleted source cannot leave a stale theme behind. Vendored, not read from the genizah: the build stays offline. A source it cannot map is a hard error naming the file and the key, never a silently black-on-black theme. ThemeSel is the clever half. Traits gained an `executes` column, so n/N over that buffer hands the whole line to Exec instead of the leading word to Look — both arms the ordinary builtin, so a stepped row does exactly what the matching mouse button on it would. Stepping the list previews each theme live. The trait is a pane property, not an output-pane branch, so any pane whose lines are commands can opt in. Goldens: leader gains SPC t t; theme's fourth NextColor no longer wraps to helix because the ring is fifteen long. New: themesel.
* focus history is a stack of locations, and the Jumplist is that same stackGabriel Schneider2026-08-01
| | | | | | | | | | | | | | | | | | | | | | | One container, not two: focus_hist (a stack of pane ids rebuilt every sync) is now jumps[] + a current pointer, and the +Jumps buffer is a RENDERING of that array — nothing copies it, nothing shadows it. prevFocus, Toggleterm, Look's directory order, Back/Forward, Last and Jumplist all walk the one list. A pane id is reused, so a location that only remembered an id would retarget after a respawn: panes now carry a monotonic serial and an entry whose slot holds a different serial is dead. trackJump compacts those out and fixes the pointer in the same pass. The push rule lives in ONE place and says: a location is worth remembering when you cannot see it any more — a different pane, or more than a bodyful of rows away in the same one. So hjkl never grows the list and 100G, a search hit and a goto-definition do. Ctrl-o/Ctrl-i walk it, SPC j j toggles the last two, SPC j l lists them. Ctrl-i IS Tab on a legacy host, where the binding simply never fires and Tab-executes is untouched; kitty reports them apart. SPC j o/i work anywhere. Two goldens moved, both the SPC ? Help listing gaining four rows.
* output panes remember the command that opened themGabriel Schneider2026-08-01
| | | | | | | | | | | | | | | | An output buffer was a file pane with a flag, and everything special about it was re-derived from outside by asking the wrong question: the buffer NAME ("+Search", "+Help"), a parallel search_kind field, and f.output predicates sprinkled through kind-agnostic code. Now it carries its Origin — the Builtin, or the lsp.Kind for the five gotos helix binds as motions rather than words — plus that command's argument, and one Traits table answers every question the scattered code used to ask: what it is called, whether n/N steps it, whether it is a doc for layout, whether Esc dismisses it, whether it saves. The name is derived FROM the command instead of being the thing that identifies it. Adding a kind of output pane is adding a row. No golden moved.
* config.zig: every binding and every piece of Look syntax in one fileGabriel Schneider2026-08-01
| | | | | | | | | | | | | | | | | | | Retargeting a key, a mouse chord or a spelling is now an edit to src/config.zig and nothing else. Three parts in reading order: pardes's own bindings (where a reader lands), the Look/Exec syntax, then the helix keymap under a banner saying hxdiff/hxparity are differential suites against real helix, so a key moved there is a divergence and not a tweak. The bindings are data a comptime loop can walk, because the builtin index is going to walk them. Duplication this cut: is/isC/isA became one hit(key, chords) over ~132 call sites, and a binding being a LIST collapses the letter-or-arrow chains; swap_enter_tab is gone, replaced by look_key/exec_key that can point anywhere; the four focus builtins' h/j/k/l lived hardcoded in two places and is now one table. No golden moved.
* structure: backends into src/{tty,gui,lsp}, pane kinds and builtins into ↵Gabriel Schneider2026-08-01
their own files The core now lies FLAT at src/ and every subdirectory is one backend, so a file being in no directory at all is what says it is core. Pane-kind bodies leave pardes.zig for term_pane.zig / file_pane.zig / output_pane.zig, leaving it the layout, the event/effect machine and the generic render loop. Builtins are one struct each in builtins.zig, and the enum is folded out of the file's own declaration list at comptime — a zig file IS a struct, so the list of builtins and the builtins themselves are the same text. Adding one is writing a struct. Key paths deliberately stay one table for the config pass. Pure refactor: no golden moved.
