v0.7.0

0.7.0

Published April 10, 2023

@quri/squiggle-lang

Language:

• New functions: List.concat, List.uniq, List.append, List.flatten, List.join, Dict.mapKeys.
• stdev and variance work for all kinds of distributions.
• Support for ==, != and + on strings.
• Support for trailing comma in arrays: arr = [5,6,] is now allowed.
• Plot.fn allows for programmatical control of min..max range in charts.
• Support for { p10: ..., p90: ... } and { p25: ..., p75: ... } in normal() and lognormal().
• Non-integer key lookups in arrays are now disallowed; arr[1.5] and arr[3/0] will result in error; previously non-integer keys got rounded to 0 or the closest integer.
• Fix for zero parameter function quirks; the checks are now stricter and some existing code might break.
• Fix for normal(5,2) * 0 special case.
• Fix for summary stats and inv function on pointMass distributions.
• Fix for inv and sample on discrete distributions.

JS API:

• sq function allows to embed Squiggle code in JS with syntax highlighting in VS Code (when VS Code extension is installed).
• value.asJS() method for easier conversion of results to JS values.

Other:

• ES6 modules build (we still provide CommonJS build as well).

@quri/squiggle-components

UI:

• New code editor based on Codemirror, with the improved syntax highlighting and auto-completion for variables and stdlib functions.
• Charts are now implemented in pure Canvas with D3 (instead of Vega), with some improvements in UI and rendering speed.

Other:

• This package is now ESM-only! We depend on D3, and D3 is ESM-only, so squiggle-components has to be ESM-only as well. If your project still uses CommonJS and you doesn't use Next.js or other smart transpiler, you might encounter problems. See this document for advice.
• Much smaller bundle size, thanks to removing some heavy dependencies.
• oneLine prop in SquiggleEditor removed (probably no one used it).
