import { SquiggleEditor } from "../../src/components/SquiggleEditor";
|
|
|
|
Squiggle supports some simple types and language features.
|
|
|
|
## Numbers
|
|
|
|
<SquiggleEditor defaultCode="4.32" />
|
|
|
|
## Distributions
|
|
|
|
There are several ways of easily entering distributions. See the [documentation](/docs/Api/Dist/) on distributions for a complete API.
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`a = normal(4,2)
|
|
b = 30 to 50
|
|
c = lognormal({mean:90, stdev: 7})
|
|
d = mixture(a,b,c, [.3, .3, .4])
|
|
d`}
|
|
/>
|
|
|
|
## Lists
|
|
|
|
Squiggle lists can accept items of any type, similar to those in Python. [API](/docs/Api/List).
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`[beta(1,10), 4, isNormalized(SampleSet.fromDist(1 to 2))]`}
|
|
/>
|
|
|
|
## Dictionaries
|
|
|
|
Squiggle dictionaries work similarly to Python dictionaries. [API](/docs/Api/Dictionary).
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`d = {dist: triangular(0, 1, 2), weight: 0.25}
|
|
d.dist`}
|
|
/>
|
|
|
|
## Functions
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`f(t) = normal(t^2, t^1.2+.01)
|
|
f`}
|
|
/>
|
|
|
|
## Anonymous Functions
|
|
|
|
<SquiggleEditor defaultCode={`{|t| normal(t^2, t^1.2+.01)}`} />
|
|
|
|
## Comments
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`// This is a single-line comment\n
|
|
/*
|
|
This is a multiple
|
|
-line comment.
|
|
*/
|
|
""
|
|
`}
|
|
/>
|
|
|
|
## Pipes
|
|
|
|
Squiggle features [data-first](https://www.javierchavarri.com/data-first-and-data-last-a-comparison/) pipes. Functions in the standard library are organized to make this convenient.
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`normal(5,2) |> truncateLeft(3) |> SampleSet.fromDist |> SampleSet.map({|r| r + 10})`}
|
|
/>
|
|
|
|
## Standard Library
|
|
|
|
Squiggle features a simple [standard libary](/docs/Api/Dist).
|
|
|
|
Most functions are namespaced under their respective types to keep functionality distinct. Certain popular functions are usable without their namespaces.
|
|
|
|
For example,
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`a = List.upTo(0, 5000) |> SampleSet.fromList // namespaces required
|
|
b = normal(5,2) // namespace not required
|
|
c = 5 to 10 // namespace not required
|
|
""`}
|
|
/>
|
|
|
|
## Number Suffixes
|
|
|
|
Numbers support a few scientific notation suffixes.
|
|
|
|
| suffix | multiplier |
|
|
| ------ | ---------- |
|
|
| n | 10^-9 |
|
|
| m | 10^-3 |
|
|
| k | 10^3 |
|
|
| M | 10^6 |
|
|
| B,G | 10^9 |
|
|
| T | 10^12 |
|
|
| P | 10^15 |
|
|
|
|
<SquiggleEditor
|
|
defaultCode={`simpleNumber = 4.32k
|
|
distribution = 40M to 50M
|
|
distribution`}
|
|
/>
