0.9.4

@quri/squiggle-lang

Standard library:

  • Added Spec.make function and @spec tag (#3113)

  • Added the basic try() function (#3137)

  • Added PointSet.support function and a new MixedSet.* namespace with several functions for working with 1-dimensional sets of points and segments (#3115, #3151)

  • Added Danger.yTransform function (#3127)

Bugfixes:

  • Fixed the issue with very slightly negative KDE values because of floating point errors (#3114)

  • Fixed parsing of x = {|...|...} -> ... statements(#3136)

Internals:

  • Use a custom PRNG (aleaPRNG) and always require seed in environment (#3006)

    • Note that this can make some models up to 2x slower, because it's hard to beat the native Math.random; but we'll make up for it with other optimizations in future releases

  • Variable stack is array-based, with up to 50% better performance in synthetic tests (#3054)

  • All Squiggle values are serializable (#3158)

  • Support pluggable runners, including the experimental webworker runner (#3158)

  • Simplified AST representation (#3136)

  • Disallow overrides of an internal function responsible for index lookups (#3135)

@quri/squiggle-components

Features:

  • Stable seeds; re-runs of the same model with the same seed will always give the identical result (#3006)

  • Added Meta+PageUp/PageDown shortcuts to control the current viewer tab (#3055)

  • Added clickable gutter lines to focus on value variables (#2980)

  • Show export data and links in Viewer (#3056)

  • Support autorun={false} prop in <SquigglePlayground> component (#3119)

Bugfixes:

  • Fixed the regression where stacktrace locations weren't clickable

  • Recognize != operators during highlighting (#3133)

  • Fixed the issue with persisting focus and collapse/expand state after errors (#3129)

  • Render negative values in pointsets correctly (#3126)

Experimental:

  • Support Spec values (#3113)

  • WebWorker runner (#3158)
