• an update for a package

0.2.0 - 2026-07-06

Added

• Automatic label placement (collision avoidance), on by default: labels
  are placed as close as possible to the requested anchor without overlapping
  drawn segments, circles, point markers or other labels. Labels without an
  explicit position are fully automatic (labels: true). Guarantees: a label
  is always closer to its own point than to any other point by a clear margin
  (never reads as the neighbor's label); the font is shrunk (85%, then 70%)
  only when no full-size position exists — and then all labels of the
  figure share the same scale. Global switch ctz-label-avoid(false),
  per-label (pos: "above", avoid: false), tunable via
  ctz-label-avoid((rings: ..., shrink: ..., assoc-factor: ...)). Angle
  labels slide along the bisector to stay clear.
• Exterior angle support (quill:0.1.0 #2): ctz-draw-angle(..., angle-type: "reflex")
  (explementary) and angle-type: "supplementary" (exterior).
• ctz-def-golden(..., inside: false) for the external golden section.
• ctz-def-translate accepts a pair of point names as the vector.
• ctz-draw(points: ..., shape: ..., size: ..., color: ...) style overrides.
• ctz-style(angle: (...)) is now honored by ctz-draw-angle.
• Greek point names render as symbols in labels ("alpha" → α, "Omega1" → Ω1).

Fixed

• Arc rendering (gloss-awe:0.0.3 #4): arcs, sectors, semicircles and compass marks were
  drawn offset by one radius (cetz anchors arcs at their start point, not
  their center) and with mirrored start/end angles.
• Systemic calc.atan2 argument-order bug affecting slope calculations,
  tangent points from an external point, sector/semicircle angles, the
  german-style right-angle mark, sloped segment labels, ellipse
  projections/tangents and automatic label placement.
• cetz version conflict (mathtext:0.0.1 #1): upgraded to CeTZ 0.5.2 — no more conflict
  when combining ctz-euclide with cetz-plot or your own cetz import, in any
  import order.
• ctz-def-golden crashed on every call.
• ctz-draw(name, sketchy: true) crashed on named lines and polygons.
• ctz-def-excenter/ctz-def-excircle vertex is now case-insensitive (the
  default silently computed the excenter opposite C).
• Feuerbach point returned the incenter instead of the tangency point.
• Tangent points from an external point used asin instead of acos.
• Duplicate labels for the same point (same content) are now drawn only once.
• Labels for point names longer than 5 characters were silently dropped.
• Grids and axes no longer drop their last line/tick to float rounding.
• Internal module names (util, draw, circle, ...) are no longer leaked
  into your document by the wildcard import (the cetz binding is still
  exported on purpose, for import cetz.draw: *).
• ctz-version is now read from typst.toml (was stuck at 0.1.0).

0.1.5

• Main-levée (hand-drawn/sketchy) style, including sketchy: true on ctz-draw
• Global style configuration variables for colors, point shapes, sizes, and mark widths
• Canvas-level clipping via ctz-canvas(clip-canvas: ...) with line/segment clipping
• Labels now render in math font by default
• Expanded docs and gallery examples for styling, main-levée, and clipping
