Squiggle language
An estimation language
Use the npm package
For instance, in a javascript project, you can
yarn add @quri/squiggle-lang
import { run } from "@quri/squiggle-lang";
run(
"normal(0, 1) * fromSamples([-3,-2,-1,1,2,3,3,3,4,9]"
).value.value.toSparkline().value;
However, for most use cases you'll prefer to use our library of react components, and let your app transitively depend on @quri/squiggle-lang.
Build for development
We assume that you ran yarn at the monorepo level.
yarn build
yarn bundle is needed for a deployment.
Other:
yarn start # listens to files and recompiles at every mutation
yarn test
# where o := open in osx and o := xdg-open in linux,
yarn coverage:rescript; o _coverage/index.html # produces coverage report and opens it in browser
Distributing this package or using this package from other monorepo packages
As it says in the other packages/*/README.mds, building this package is an essential step of building other packages.
Information
Squiggle is a language for representing probability distributions, as well as functions that return probability distributions. Its original intended use is for improving epistemics around EA decisions.
This package, @quri/squiggle-lang, contains the core language of squiggle. The main feature revolves around evaluating squiggle expressions. Currently the package only exports a single function, named "run", which from a squiggle string returns an object representing the result of the evaluation.
If using this package for tests or as a dependency, typescript typings are available and recommended to be used.
This package is mainly written in ReScript, but has a typescript interface.
ReScript has an interesting philosophy of not providing much in the way of effective build tools. Every ReScript file is compiled into .bs.js and .gen.ts files with the same name and same location, and then you can use these files in other .js files to create your program. To generate these files to build the package, you run yarn build.
.gen.ts files are created by the @genType decorator, which creates typescript typings for needed parts of the codebase so that they can be easily used in typescript. These .gen.ts files reference the .bs.js files generated by rescript.
