1.2.2 (2021-08-24)

  • Blocks that accept child values can now be called without braces around them
  • Fixed confusing error messages caused by mesh commands being unavailable in certain scopes
  • Made script evaluation cancellable in case of infinite iteration or recursion
  • Fixed bug in Viewer app where view fails to refresh after loading geometry
  • Improved and simplified error handling logic

1.2.1 (2021-08-19)

  • Fixed crash when for loop end index < start index
  • Improved print log output, especially for arrays/tuples and nested values
  • Added Loggable protocol for stringifying values logged using the ShapeScript print command
  • Replaced TokenType.description with TokenType.errorDescription to aid debugging
  • Text now supports using \n for line-breaks (this was documented as working, but never implemented)
  • Fixed confusing error message when first value of tuple matches expected type
  • Fixed nonsensical error message when a command is used in an expression
  • Bumped Euclid to 0.5.9, which includes fixes for extruded paths
  • Extruding along a compound path now forms a union between the resultant shapes
  • Fixed typos and improved help documentation
  • Fixed member lookup precedence
  • Improved test coverage

1.2.0 (2021-08-15)

  • Improved progressive rendering logic, reducing wait before seeing first results in viewer
  • Geometry cache is now limited to ~1GB per open document instead of being unbounded
  • Cached geometry is now cleared when document is closed instead of persisting for app lifetime
  • Invalid font names now produce an error instead of silently falling back to Helvetica
  • Paths are now drawn in white when background is set to a dark color or texture
  • Fixed an index out-of-bounds crash in the Levenshtein distance function
  • Bumped Euclid to 0.5.8, which includes several bug fixes
  • Renamed GeometryType.none to the more descriptive GeometryType.group
  • Made Geometry.mesh and Geometry.associatedData properties thread-safe using NSLock
  • Removed Scene.deepCopy() and Geometry.deepCopy() methods as instances are now thread-safe
  • Moved selection logic out of ShapeScriptLib and into Viewer example application
  • Fixed bug in Viewer where geometries would be deselected during progressive loading
  • Added LRUCache dependency

1.1.6 (2021-08-04)

  • Paths are now drawn using polygons strips, which looks sharper and renders more consistently
  • Made further improvements to cancelling in-progress rendering when reloading a file
  • Bumped Euclid to 0.5.4, which includes several bug fixes and performance improvements
  • Improved performance when rendering scenes with nested CSG operations or groups
  • Fixed rendering and bounds calculation of non-planar extruded shapes

1.1.5 (2021-08-02)

  • Info window in ShapeScript Viewer no longer includes imported models in texture count
  • Fixed a regression in ShapeScript Viewer 1.1.4 where error message wouldn't refresh correctly on reload
  • Improved error messaging for errors that occur in an imported file
  • Reloading a partially-rendered scene should now terminate the rendering more quickly, freeing up CPU
  • Rendering is now cancelled when document is closed (previously it continued in background)
  • Improved responsiveness of incremental rendering for complex scenes
  • Program source and statements properties are now public

1.1.4 (2021-07-31)

  • Increased time precision of document file monitoring in ShapeScript Viewer app
  • Improved threading a progress logging in ShapeScript Viewer app
  • Added Linux support for ShapeScriptLib (excluding rendering and text functions)
  • Made static color constants immutable
  • Bumped Euclid version to 0.5.3

1.1.3 (2021-07-10)

  • Fixed assertion failure if a parsing error occurs at the last character in the .shape file
  • Fixed bug in Path plane calculation that could result in corrupted extrusion shapes
  • Fixed a tessellation bug affecting anti-clockwise polygons

1.1.2 (2021-07-03)

  • Fixed bug where CRLF was treated as two separate linebreaks, resulting in a crash
  • Error column indicator is now better aligned when code contains wide characters (e.g. emoji)
  • Fixed inverted black/white squares on chessboard example

1.1.1 (2021-06-26)

  • Fixed operator associativity (addition/subtraction were previously right-associative)
  • Performing CSG operations on complex geometry no longer causes a stack overflow
  • Bumped Euclid version to 0.4.5

1.1.0 (2021-04-08)

  • Added support for background colors and images
