Luix v1.3.0 - The Tokens & Fonts Update

New diagnostics (gated by luix.propValidation.enabled, on by default)

• Numeric-range warnings — Transparency = 1.5, Rotation = 720,
  BorderSizePixel = 100, etc. Per-prop bounds.
• TextScaled gotcha — TextScaled = true with a pure-scale Size
  (or no Size) collapses text to zero — now flagged with a fix
  recommendation.

Color contrast warnings (off by default)

luix.contrastWarnings.enabled — flags any TextColor3 whose
WCAG-AA contrast ratio against the nearest ancestor's
BackgroundColor3 falls below 4.5:1. Both colors must be literal
Color3 expressions; reactive Fusion/Vide values are skipped.

Design tokens beyond color

Mirror of luix.palette for two more types:

• luix.spacing — type UDim. to surface entries like
  spacing.md → UDim.new(0, 16).
• luix.fonts — type Font. to surface entries like
  fonts.display → Font.fromName("Gotham", Enum.FontWeight.Bold).

Empty by default; opt-in via user config.

Color3 → palette extractor

Cursor on any Color3 literal → 💡 Save Color3 to luix.palette… —
prompts for a token name and a target (User / Workspace settings).
The literal is added to luix.palette so it surfaces in future
Color3. completions.

Frame-stats CodeLens (off by default)

luix.frameStatsLens.enabled — ▸ Frame — 24 descendants, 4 layers deep above every meaty subtree. luix.frameStatsLens.minDescendants
(default 5) controls the threshold.

Workspace-wide validation summary (off by default)

luix.workspaceValidation.enabled — the Luix sidebar shows
"Project diagnostics — N warnings · M errors across X files".
Click jumps to the Problems panel. Aggregates Luix + every other
publisher's diagnostics.

Class picker on ( (off by default)

luix.classNameCompletion.triggerOnOpenParen — typing e( (without
a quote) opens the class picker; accepting inserts the full
"ClassName", { … }) body. Off by default because ( is a broad
trigger; on saves one keystroke per element when enabled.

CFrame.Angles snippets

cfangles → CFrame.Angles(math.rad(…), math.rad(…), math.rad(…))
cfanglesrad → CFrame.Angles(…, …, …) (radians form)

Background — workspace index persistence (on by default)

luix.indexPersistence.enabled — the parsed component index is now
saved to disk between sessions; unchanged files skip re-parsing on
cold start. Speeds up activation on large workspaces with no
behavioral difference. Disable to keep Luix offline.

Background — opt-in Roblox API-dump augmentation

luix.useRobloxApiDump — fetch the community-maintained
Mini-API-Dump JSON once a day and add any new properties Roblox has
shipped to existing classes' completion lists. Additive only — the
hand-curated built-in data still wins on conflicts.

Roblox font family + weight autocomplete

• Inside Font.fromName("…"), the family dropdown surfaces 36
  built-in Roblox families with their supported weights. Popular UI
  families (BuilderSans, Gotham, Roboto, SourceSansPro, …) sort first.
• After Enum.FontWeight. inside a Font.fromName(...) call, the
  weight dropdown shows ONLY the weights the family actually ships.
  Font.fromName("Cartoon", Enum.FontWeight.|) lists just Regular;
  Font.fromName("Roboto", Enum.FontWeight.|) lists all nine.
• luix.customFonts lets you register custom font families and
  their supported weights — they merge into the same completions,
  surface above built-ins, and weight-filter the same way.

Font (deprecated) removed from TextLabel / TextButton / TextBox

These classes no longer suggest the deprecated Font property —
only FontFace shows up in the completion list. The existing
deprecation diagnostic still catches anyone who writes
Font = Enum.Font.X and offers the Replace with FontFace = …
quick-fix.

Smarter value completion for Color3 / UDim / Font props

Accepting BackgroundColor3 / TextColor3 / Padding / FontFace
now inserts a Color3. / UDim. / Font. prefix and auto-opens
the suggest dropdown. The dropdown lists:

• Built-in constructors first — fromRGB, fromHex, new,
  fromHSV (for Color3); new (for UDim); fromName, fromId (for
  Font). Picking one inserts the full call with per-channel tab stops
  preserved.
• Tokens defined in your settings below — palette.primary,
  spacing.md, fonts.display, … swap the prefix for the literal
  expression.

Type f to filter to constructors; type p (or s / fonts) to
filter to tokens.

RichText <font> / <stroke> / <mark> — no more presumptuous defaults

Accepting one of these tags now leaves the attribute slot empty and
parks the cursor inside the tag. Type any letter and the attribute
completion fires — pick color, size, weight, etc. and the
value-with-quote pair fills in. Previously the snippet always
pre-filled color="…" regardless of intent.

Other improvements

• Prop completion no longer doubles trailing commas: typing Bac,
  then accepting BackgroundColor3 produces a single trailing comma
  with the cursor after it, regardless of the existing ,.
• Prop / anchor-preset completions are now gated to key position —
  typing FontFace = Font.| no longer surfaces BackgroundColor3 /
  anchor:c / etc. alongside the font constructors.
• All settings now live under the luix.* prefix. The silent
  fallback to legacy reactLuauPropsHelper.* keys has been removed
  because VS Code's inspect() could mistake a user-set {} (equal
  to the default) for "not set" and quietly pick up the old keys.
  Anyone with stale reactLuauPropsHelper.* entries needs to rename
  them to luix.* (the format is identical).
• All user-visible strings, diagnostic codes, and the diagnostic
  collection have been re-branded from react-luau-props-helper to
  luix so the Problems panel and hover tooltips show the right
  source.
• .vscodeignore extended to exclude devforum-post/, design SVG /
  PNG drafts, PUBLISHING.md, lockfile, and tooling configs.
