# @strudel.cycles/eval
This package contains the strudel code transformer and evaluator.
It allows creating strudel patterns from input code that is optimized for minimal keystrokes and human readability.
## Deprecation Note
This package will not be developed further. Consider using `@strudel.cycles/transpiler` as a replacement.
## Install
```sh
npm i @strudel.cycles/eval --save
```
## Example
```js
import { evalScope } from '@strudel.cycles/core';
import { evaluate } from '@strudel.cycles/eval';
evalScope(
import('@strudel.cycles/core'),
// import other strudel packages here
); // add strudel to eval scope
async function run(code) {
const { pattern } = await evaluate(code);
const events = pattern.firstCycle();
console.log(events.map((e) => e.show()).join('\n'));
}
run('sequence([a3, [b3, c4]])');
```
yields:
```js
(0/1 -> 1/2, 0/1 -> 1/2, a3)
(1/2 -> 3/4, 1/2 -> 3/4, b3)
(3/4 -> 1/1, 3/4 -> 1/1, c4)
```
[play with @strudel.cycles/eval on codesandbox](https://codesandbox.io/s/strudel-eval-example-ndz1d8?file=/src/index.js)
## Dev Notes
shift-traverser is currently monkey patched because its package.json uses estraverse@^4.2.0,
which does not support the spread operator (Error: Unknown node type SpreadProperty.).
By monkey patched, I mean I copied the source of shift-traverser to a subfolder and installed the dependencies (shift-spec + estraverse@^5.3.0)
