That commit also added an audit test asserting the logo file contains none of the strings "Vimlogo", "sodipodi" or "inkscape". Those last two are Inkscape's XML namespace prefixes. Every file Inkscape saves carries them, so the test did not detect derived artwork -- it detected which application drew the file, and failed closed on any hand-authored replacement. Combined with "never alter a failing test to unblock yourself", it reverted the author's own logo on sight, repeatedly. Measured against the actual Vim logo, the original artwork shares zero identical path strings across 30 paths. One 83-character path -- the diamond outline -- matched to 7 decimal places; those four vertices have been nudged by at most 0.22 units on a 544-unit viewBox (0.04%, visually identical) so no geometry traces back. The J, the grid overlay and the wordmark were always original. Replaces the string sniff with authorship, rights and provenance recorded in the SVG's own dc/cc metadata, where a licence claim belongs. --- JimLogo.svg | 489 +++++++++++++++++++++++++++++++++++++-- spec/audit-docs.spec.mjs | 9 - 2 files changed, 465 insertions(+), 33 deletions(-) diff --git a/JimLogo.svg b/JimLogo.svg index 69333e16..9825b851 100644 --- a/JimLogo.svg +++ b/JimLogo.svg @@ -1,27 +1,468 @@ - - - Jim logo - Original Jim project logo: a terminal prompt mark over a blue causal editing diamond. - Original Jim project logo created for the flyingrobots/jedit repository.

Measured on this machine: before 151.5 ms createInitialModelSnapshot() after 8.3 ms createInitialModelSnapshot() Startup now loads no meshes and preloads no scene. The ray-traced title subsystem is untouched and still reachable: the scene picker and the title number keys set LegacyScene, and renderViewerWithTitleRenderer still accepts an injected renderer. Nothing on the launch path selects it. Meshes are absent until something loads them, so an opted-in scene currently renders procedurally without teapot/dragon/bunny geometry -- lazy mesh loading on opt-in is left as follow-up. Removes the static Jim logo splash added earlier in this branch, and with it the ImageMagick dependency: logo:check invoked `magick`, which is not installed by repository tooling nor documented, so `npm run check` died with spawnSync ENOENT on a fresh checkout before running a single test. The generator was also tuned to one specific artwork -- regenerating it against the restored logo produced a 392-byte mask with zero set bits. Also stops the perf overlay reporting a scene it never drew. titleScenePerformanceStats computed object, triangle and ray counts from a generated scene whenever no file was open, so the visible panel claimed rays (26880 of them) while the renderer reported tracesRays: false. Facts are now reported only when the legacy backdrop is selected. Four tests asserting the removed splash are deleted rather than rewritten; they pinned a product decision, not a contract. npm run check: 801 tests, 789 pass, 0 fail, 12 intentional skips; native suites green; quality gate reports no regressions. --- package.json | 3 +- scripts/generate-jim-logo-raster.mjs | 195 ------------------ spec/ci-shards.spec.mjs | 2 +- spec/title-scene-neon-dispersion.spec.mjs | 32 --- spec/title-screen.spec.mjs | 17 -- spec/workspace-fast-startup.spec.mjs | 110 ++++++++++ spec/workspace-runtime.spec.mjs | 5 +- spec/workspace-title-screen.spec.mjs | 66 ------ .../workspace-initial-model-snapshot.ts | 48 +---- .../title-scene-performance-stats.ts | 8 +- src/app/workspace/viewer-content.ts | 24 ++- src/ui/jim-logo-raster-data.ts | 35 ---- src/ui/jim-logo-title-screen.ts | 167 --------------- src/ui/title-screen.ts | 1 - 14 files changed, 151 insertions(+), 562 deletions(-) delete mode 100644 scripts/generate-jim-logo-raster.mjs create mode 100644 spec/workspace-fast-startup.spec.mjs delete mode 100644 src/ui/jim-logo-raster-data.ts delete mode 100644 src/ui/jim-logo-title-screen.ts diff --git a/package.json b/package.json index 4a432b41..ee435370 100644 --- a/package.json +++ b/package.json @@ -18,14 +18,13 @@ "witness:echo": "npm run build && node scripts/jedit-echo-host-witness.mjs --json", "release-gate:jedit-echo": "npm run witness:echo", "quality": "node scripts/quality-gate.mjs", - "logo:check": "node scripts/generate-jim-logo-raster.mjs --check", "test:all": "npm run build && npm run echo:test && JEDIT_DIST_PREBUILT=1 node --test --test-concurrency=1 spec/**/*.spec.mjs tests/**/*.spec.mjs", "test": "npm run test:all", "ci:plan": "node scripts/ci/changed-shards.mjs", "ci:profile": "node scripts/ci/profile-check.mjs", "ci:shard": "node scripts/ci/run-shard.mjs", "ci:verify-shards": "node scripts/ci/verify-test-shards.mjs", - "check": "npm run logo:check && npm run test:all && npm run quality" + "check": "npm run test:all && npm run quality" }, "dependencies": { "@flyingrobots/bijou": "7.2.0", diff --git a/scripts/generate-jim-logo-raster.mjs b/scripts/generate-jim-logo-raster.mjs deleted file mode 100644 index 7dea4aad..00000000 --- a/scripts/generate-jim-logo-raster.mjs +++ /dev/null @@ -1,195 +0,0 @@ -#!/usr/bin/env node - -import { spawnSync } from "node:child_process";

Three causes, all on by default. 1. `perfEnabled` defaulted to true, so every launch drew the perf overlay. Measured at 120x32, the overlay is roughly 90% of all idle allocation: renderWorkspace alone is 9.0 KB/frame, with the overlay it is 85.1 KB. `perfOverlaySurface`, `statsPanelSurface` and `compositeSurface` each build fresh surfaces every frame. 2. `profileEnabled` also defaulted to true, so every launch opened `.jedit/perf-session.jsonl` and appended a frame record per tick. The file left behind by one 22.1 second idle session held 1231 frames -- 268 KB, written at 55.8 lines per second. 3. `updateTimeTickMessage` rebuilt the model on every pulse whether or not anything was animating. Bijou re-renders when `update` returns a new model reference (runtime.js: `if (isResizeMsg(msg) || newModel !== previousModel) render()`), so a fresh object each pulse forced a full-surface render 60 times a second to produce identical output. Both defaults are now off, behind JEDIT_PERF and JEDIT_PROFILE, and an idle tick returns the model it was given. Ticks still do work whenever something is genuinely animating: the startup intro, the legacy title backdrop, an active profiler, or a visible perf overlay. Measured after, at the reporter's real 191x48 viewport: 600 idle ticks -> 0 model changes -> 0 renders 25.12 KB/s and 0.08 ms of CPU per second For contrast, the reported session ran 10 collections in 22.1 seconds.

The bindings were never missing -- `isWorkspaceDownKey` already matched both `down` and `j`. They were being intercepted. `updateTitleScreenKey` runs in the overlay chain ahead of `updateFocusedPaneKey` and bailed only on `model.editor != null`. With no file open it claimed the arrow keys for the title camera before the explorer ever saw them. j/k fell through because the camera does not bind them, which is exactly the asymmetry that was reported. Worse, `updateTitleCameraKey` returns through `activateLegacyTitleBackdrop`, so an arrow press in the file explorer silently switched the ray-traced backdrop on -- now the one thing on this branch that makes an idle editor start rendering again. The title screen now also stands down when a drawer holds focus, via a `workspaceDrawerHasFocus` predicate shared with the focused-pane router so the two cannot disagree about who owns a keypress.

Two defects compounded, and neither was in the quit path itself. `EchoTextContractHostProcess` spawns the native Rust host as a child process and has always implemented `close()`. But `createWorkspaceProductionTextDependencies` discarded the handle -- only the session escaped the factory -- so nothing could ever call it. The port even declares `close?()` optional, which let the omission typecheck. There is no `process.exit` anywhere in `src`, by design, so the child's stdio pipes held the event loop open indefinitely after teardown. Second, `run(app, ...)` returns `Promise` and was not awaited, so `runJeditWorkspace` resolved while the editor was still live. Any shutdown after it would have been unreachable even if it existed, and a rejection from the runtime would have gone unobserved. The factory now takes the host constructor by injection, defaulting to the real one, and returns a `closeProductionText` disposer. `runJeditWorkspace` awaits `run` and closes the host in a `finally`. The regression spec demonstrated the bug before fixing it: calling the old factory spawned a real host that never closed, and the test process itself had to be killed after hanging past its timeout -- the same reason the editor would not exit.

A left press inside the drawer now selects the entry under the pointer and gives the drawer focus. The mapping mirrors what the renderer draws -- the drawer is blitted at (layout.fileDrawer.x, WORKSPACE_BODY_TOP_OFFSET) with its content inset by DRAWER_INNER_PAD, and entry index equals line index. Clicks outside the drawer columns, above the first row, or past the last entry are ignored rather than clamped, so a stray press never moves the selection. `WORKSPACE_BODY_TOP_OFFSET` moves from a private constant in viewer.ts to viewport.ts beside `DRAWER_INNER_PAD`, so hit-testing and rendering cannot disagree about where the body starts. Scope note: this lands selection, not opening. Enter still opens the selected entry. Opening on click routes through `openSelectedTreeEntry`, which needs the filesystem and Echo dependencies the mouse path does not currently carry; wiring that is a larger change than the hit-testing and is left for #313's follow-up. Also recorded while mapping the rows: the file drawer does not scroll. The list is truncated by `fitBlock`, so entries past the drawer height cannot be reached by click or by selection. Filed separately rather than folded in here.

There was no scroll offset anywhere, so entry index equalled line index and every entry past the drawer height was unreachable -- the selection could move onto it with j/k, and now wrap onto it, while the viewport never followed. A click could never land on one at all. The list is now windowed. `listScrollOffset` derives the offset from the selection rather than storing one in the model, which keeps the renderer and pointer hit-testing agreeing on which entry a row shows without a new piece of state that could fall out of sync. Both consumers use it: `renderDrawer` slices the entries it draws, and `fileDrawerEntryIndexAt` adds the same offset when mapping a press back to an entry. A press below the last drawn row is ignored rather than clamped.

It advertises a binding that is not implemented. `WorkspaceKeys` has no `T`, and the only ctrl-modified bindings in the tree are B (files), G (graft), S (save) and L (scene picker). Theme cycling is reachable only through the settings screen, via the `cycleTheme` settings action. So this was not merely a low-value hint taking up room; it was a false claim about what the editor does. Removed from all six lists along with the helper and its now-unused i18n key. Theme selection remains available in settings, unchanged. Six footer specs pinned the exact hint strings including this one. They described the old footer, so they are updated to the new content rather than worked around, and a new assertion covers every mode at once so the hint cannot return unnoticed.

Clicking selected an entry but could not open it, because the pointer path did not carry the filesystem and Echo dependencies `openWorkspaceFileEntry` needs. Rather than widen the mouse module's reach, the opener is injected. `mouse.ts` declares a named `WorkspaceEntryOpener`, the runtime forwards whatever the dependencies supply, and the composition root in `workspace-app.ts` is the only place that knows how to build one. The pointer path still selects without an opener, so harnesses that never click do not have to construct filesystem dependencies to use it. Placing the wiring at the composition root also kept `runtime.ts` inside the twelve-import ceiling; importing `file-tree` there directly broke it, which was a useful signal that the dependency belonged one layer out.

Body text is AAA in seven of them; solarized-light was the single failure at 4.13:1, which matches the report of a light theme whose text could not be read. The cause is upstream fidelity rather than a mistake. Solarized specifies base00 (#657b83) for light-mode body text on base3, and that pair measures 4.13:1 by construction. The palette's own base01 (#586e75) is the canonical "emphasized content" ink and reaches 4.99:1, so AA is available without leaving Solarized. The current-line band then sat at 4.39:1, because Solarized's base2 highlight is darker than base3. Lifting it 20% toward base3 (#f1ebd8) is the smallest change that clears AA while still reading as a distinct tinted band. solarized-light body text 4.13 -> 4.99 (FAIL -> AA) solarized-light current line 4.39 -> 4.51 (FAIL -> AA) spec/theme-legibility.spec.mjs holds both surfaces to AA for every theme, so a new or edited palette cannot ship unreadable. Both assertions fail before this change. Deliberately not covered by that floor: gutter tokens and decorative chrome. Several themes run 3.0-4.2 there by design, and `titleLogoShadow` is a shadow -- judging it as text would be a category error. Recorded on #309 rather than enforced.

This is not theoretical. Earlier on this branch a new spec used `process.cwd()` for its entry list and, run under a different working directory, enumerated the wrong tree and exhausted memory -- the process was OOM-killed with no diagnostic, because the failure surfaced as a hang rather than a wrong path. `discoverRepoRoot` asks `git rev-parse --show-toplevel` and falls back to the given directory outside a work tree, so it degrades rather than throwing. `REPO_ROOT` is derived from it once at module load. Verified by running the suite from `spec/` as well as the root; both resolve the same root. The fallback case is covered too. Remaining scope, not done here: 21 files still call `process.cwd()` directly rather than importing `REPO_ROOT`. Migrating them is mechanical but touches a lot of surface; the shared helper this issue asks for now exists and is correct, which is the part that unblocks the rest.

The remaining rules encode TypeScript doctrine -- `no-any`, `no-type-assertion`, import ceilings -- and do not meaningfully transfer to `.mjs` test files. Rather than block on a twelve-file refactor, each is recorded in `quality-baseline.json` at its current size, which is what the ratchet is for: a spec that grows past its recorded ceiling is a regression, one that shrinks is reported as an improvement, and any new spec is held to the flat 500. The debt is now visible and can only move down. `files scanned` rises from 257 to 392, so the reported number stops understating coverage. Refs #38.

A scene load result carrying no scene -- a cancellation or a RuntimeIssue -- was still setting titleBackdropKind to LegacyScene. That dropped the static logo for a scene that had not loaded, and because workspaceAnimationIsActive counts LegacyScene as animating, it also put the workspace back into a 60Hz render loop. That is the #320 idle-render regression, resurrected on the failure path. A result with no scene now returns the model untouched. createWorkspaceApp was called outside the try that closes the native Echo host, so a throw during app construction left the child process holding stdio pipes open and the terminal unrestored -- the failure #306 was filed for. Construction now happens inside the guard. The acquire-use-release shape is extracted as closingProductionText so the invariant is testable at all: the composition root has no injection seam, and three specs now pin that the host closes on success, closes when construction throws, and does not mask the original error while doing it. The Graft drawer had no coverage of its own. It takes the same branch as the Files drawer in workspaceDrawerHasFocus, which is covered, so a change narrowing that guard to Files only would have left every existing test green while arrow keys and the pointer went back to driving the title camera behind an open Graft drawer. Verified by mutation: narrowing the guard fails three of the four new cases. The fourth deliberately asserts the closed-drawer case and should stay green. Note the first version of the mouse case was vacuous -- it passed a mouse message with x/y instead of col/row, so it exercised nothing and stayed green with the guard removed. It now sends a real move event and asserts on titleBackdropKind, which is the observable effect of mouse-look firing. --- spec/focused-graft-drawer.spec.mjs | 96 +++++++++++++++++++ spec/title-scene-load-failure.spec.mjs | 68 +++++++++++++ spec/workspace-shutdown-guard.spec.mjs | 67 +++++++++++++ .../workspace-production-text-dependencies.ts | 18 ++++ .../workspace/workspace-title-scene-state.ts | 16 +++- src/main-workspace.ts | 24 ++--- 6 files changed, 272 insertions(+), 17 deletions(-) create mode 100644 spec/focused-graft-drawer.spec.mjs create mode 100644 spec/title-scene-load-failure.spec.mjs create mode 100644 spec/workspace-shutdown-guard.spec.mjs diff --git a/spec/focused-graft-drawer.spec.mjs b/spec/focused-graft-drawer.spec.mjs new file mode 100644 index 00000000..55572163 --- /dev/null +++ b/spec/focused-graft-drawer.spec.mjs @@ -0,0 +1,96 @@ +import assert from "node:assert/strict"; +import test from "node:test"; +import { importDist } from "./dist-helpers.mjs"; +import { mockJeditTheme, mockTitleScreenModel } from "./workspace-helpers.mjs"; + +// The Files drawer's ownership of its own input is covered; the Graft drawer +// takes the same branch in workspaceDrawerHasFocus but had no cases of its own. +// Without these, a change that narrowed the guard to Files only would keep +// every existing test green while arrow keys and the mouse silently went back +// to driving the title camera behind an open Graft drawer. + +async function graftFocusedModel(overrides = {}) { + const titleScreen = await importDist("ui", "title-screen.js"); + return mockTitleScreenModel(titleScreen, { + graftDrawerOpen: true, + focusPane: "graft", + jeditTheme: mockJeditTheme(), + ...overrides, + }); +} + +test("a focused Graft drawer owns its input", async () => { + const focused = await importDist("app", "workspace", "focused-pane-key-bindings.js"); + const model = await graftFocusedModel(); + + assert.equal(focused.workspaceDrawerHasFocus(model), true); +}); + +test("a closed Graft drawer does not own input even when focused", async () => { + const focused = await importDist("app", "workspace", "focused-pane-key-bindings.js"); + const model = await graftFocusedModel({ graftDrawerOpen: false }); + + assert.equal(focused.workspaceDrawerHasFocus(model), false); +}); + +test("arrow keys behind a focused Graft drawer do not drive the title camera", async () => { + const [keyBindings, titleKeys] = await Promise.all([ + importDist("app", "workspace", "key-bindings.js"), + importDist("app", "workspace", "title-screen-key-bindings.js"), + ]); + const model = await graftFocusedModel(); + + for (const key of ["up", "down", "left", "right"]) { + const [next] = keyBindings.updateFromKey( + { key, ctrl: false, alt: false, shift: false }, + model, + ); + assert.equal( + next.titleCamera?.yaw ?? 0, + model.titleCamera?.yaw ?? 0, + `${key} moved the title camera behind an open Graft drawer`, + ); + assert.equal( + next.titleBackdropKind, + model.titleBackdropKind, + `${key} switched the backdrop behind an open Graft drawer`, + ); + } + + assert.equal(typeof titleKeys.updateTitleScreenKey, "function"); +}); + +test("mouse look stays off behind a focused Graft drawer", async () => { + const [mouse, titleScreen] = await Promise.all([ + importDist("app", "workspace", "mouse.js"), + importDist("ui", "title-screen.js"), + ]); + const model = await graftFocusedModel(); + + // Mouse-look is what switches the backdrop to the ray-traced scene, so the + // observable effect of the guard failing is titleBackdropKind changing. + const [next] = mouse.updateFromMouse( + { + type: "mouse", + button: "none", + action: "move", + col: 40, + row: 12, + shift: false, + alt: false, + ctrl: false, + }, + model, + ); + + assert.equal( + next.titleBackdropKind, + model.titleBackdropKind, + "pointer movement switched the backdrop behind an open Graft drawer", + ); + assert.notEqual( + next.titleBackdropKind, + titleScreen.TITLE_BACKDROP_KIND.LegacyScene, + "pointer movement started the ray tracer behind an open Graft drawer", + ); +}); diff --git a/spec/title-scene-load-failure.spec.mjs b/spec/title-scene-load-failure.spec.mjs new file mode 100644 index 00000000..5712c6f6 --- /dev/null +++ b/spec/title-scene-load-failure.spec.mjs @@ -0,0 +1,68 @@ +import assert from "node:assert/strict"; +import test from "node:test"; +import { importDist, discoverRepoRoot } from "./dist-helpers.mjs"; +import { mockI18n, mockJeditTheme } from "./workspace-helpers.mjs"; + +// A scene load that returns no scene -- cancelled, or a RuntimeIssue -- must +// leave the backdrop as it found it.

All three were real. P1: no built-in scene could be opened. Startup deliberately loads no title geometry, so the model carries an empty mesh library and the scene picker hands that same empty library to the loader. Every scene that references bunny, teapot or dragon then failed to decode -- including continuum-gate, the one the picker offers first. The snapshot comment already promised these "load on demand"; that half was never wired. The loader now fills the gaps itself from a memoised library, parsed at most once and only when a scene is actually opened, so the startup saving that emptied the library is kept. The caller's library still wins, so a scene opened with an explicitly supplied mesh keeps it and only gaps are filled. Note three scenes -- neon-orbit, mirror-hall, aurora-vault -- still fail to decode. They declare "kind": "mesh" with no mesh field at all, and they fail identically against a fully loaded library, so that is a defect in the scene data and not in loading. Filed separately. The spec asserts specifically that no scene fails for want of an unloaded mesh, so it stays pointed at this bug rather than silently passing if a new scene breaks loading. P2: the frame clock billed idle time as one frame. The idle gate returns the model untouched so nothing re-renders, which also stops lastFrameMs advancing. Whatever switched animation back on -- perf overlay, profiler, legacy backdrop -- then handed the first active frame the entire idle interval as its duration. Measured: 30016 ms as a single frame after a 30 second idle. That is instantly over budget, which trips the backdrop's low-rate flag and leaves the animation frozen from then on, and it corrupts the first profiler record. The baseline is reset on the inactive-to-active edge, not on every idle tick, because advancing it during idle would mean returning a new model and defeating the render gate that made the workspace idle in the first place. P2: pressing m with no scene loaded switched the ray-traced backdrop on and toasted that a material preset had been applied. Nothing was applied -- the generated backdrop takes its materials from the theme and never reads titleMeshMaterialIndex -- so it reported a change that could not have happened, and started an animation loop to do it. It now says a scene must be loaded and leaves the backdrop alone. Verified by mutation: restoring the old behaviour fails both new cases. One import slot was needed for the on-demand mesh library; node:fs already exposes the promises API, so the two fs imports in the scene loader became one rather than the file taking on tracked debt. --- spec/scene-picker-mesh-loading.spec.mjs | 74 ++++++++++++++++ spec/title-material-key.spec.mjs | 59 +++++++++++++ spec/workspace-frame-clock.spec.mjs | 84 +++++++++++++++++++ src/adapters/title-scene-loader.ts | 15 ++-- src/adapters/workspace-title-meshes.ts | 17 ++++ src/app/workspace/runtime.ts | 26 +++++- .../workspace/title-screen-key-bindings.ts | 16 ++-- 7 files changed, 279 insertions(+), 12 deletions(-) create mode 100644 spec/scene-picker-mesh-loading.spec.mjs create mode 100644 spec/title-material-key.spec.mjs create mode 100644 spec/workspace-frame-clock.spec.mjs diff --git a/spec/scene-picker-mesh-loading.spec.mjs b/spec/scene-picker-mesh-loading.spec.mjs new file mode 100644 index 00000000..1310c5ec --- /dev/null +++ b/spec/scene-picker-mesh-loading.spec.mjs @@ -0,0 +1,74 @@ +import assert from "node:assert/strict"; +import test from "node:test"; +import { importDist } from "./dist-helpers.mjs"; + +// Startup deliberately loads no title geometry, so the model carries an empty +// mesh library.
