-
-To prevent unwanted runtime errors, this project uses [eslint](https://eslint.org/).
-
-- You can check for lint errors by running `pnpm lint`
-
-There are also eslint extensions / plugins for most editors.
-
-## Running Tests
-
-- Run all tests with `pnpm test`
-- Run all tests with UI using `pnpm test-ui`

-## Running all CI Checks
-
-When opening a PR, the CI runner will automatically check the code style and eslint, as well as run all tests.
-You can run the same check with `pnpm check`

 The project is split into multiple [packages](https://github.com/tidalcycles/strudel/tree/main/packages) with independent versioning.
-When you run `pnpm i` on the root folder, [pnpm workspaces](https://pnpm.io/workspaces) will install all dependencies of all subpackages. This will allow any js file to import `@strudel.cycles/<package-name>` to get the local version,

-pnpm --filter "./packages/**" publish --dry-run
-
-# the last command was only a dry-run, make sure everything looks ok, if yes, run the same command without flag
 ```
 
-To manually publish a single package, increase the version in the `package.json`, then run `pnpm publish`.
-Important: Always publish with `pnpm`, as `npm` does not support overriding main files in `publishConfig`, which is done in all the packages.
-
 ### New Packages
 
 To add a new package, you have to publish it manually the first time, using:
 
 ```sh

 ## deploy
 
-### 1. fork the [strudel repo on github](https://github.com/tidalcycles/strudel.git)
+1. in your fork, go to settings -> pages and select "Github Actions" as source
-
+2. edit `website/public/CNAME` to contain `<your-username>.github.io/strudel`
-### 2. clone your fork to your machine `git clone https://github.com/<your-username>/strudel.git strudel && cd strudel`
+3. edit `website/astro.config.mjs` to use site: `https://<your-username>.github.io` and base `/strudel`
-
+4. go to Actions -> `Build and Deploy` and click `Run workflow`
-### 3. create a separate branch like `git branch patternuary && git checkout patternuary`
+5. view your patterns at `<your-username>.github.io/strudel/swatch/`
-
-### 4. save one or more .txt files in the my-patterns folder
-
-### 5. edit `website/public/CNAME` to contain `<your-username>.github.io/strudel`
-
-### 6. edit `website/astro.config.mjs` to use site: `https://<your-username>.github.io` and base `/strudel`, like this
-
-```js
-const site = 'https://<your-username>.github.io';
-const base = '/strudel';
-```
-
-### 7. commit & push the changes
-
-```sh
-git add . && git commit -m "site config" && git push --set-upstream origin
-```
-
-### 8. deploy to github pages
-
-- go to settings -> pages and select "Github Actions" as source
-- go to settings -> environments -> github-pages and press the edit button next to `main` and type in `patternuary` (under "Deployment branches")
-- go to Actions -> `Build and Deploy` and click `Run workflow` with branch `patternuary`
-
-### 9. view your patterns at `<your-username>.github.io/strudel/swatch/`
 
 Alternatively, github pages allows you to use a custom domain, like https://mycooldomain.org/swatch/. [See their documentation for details](https://docs.github.com/en/pages/configuring-a-custom-domain-for-your-github-pages-site).
-
-### 10. optional: automatic deployment
-
-If you want to automatically deploy your site on push, go to `deploy.yml` and change `workflow_dispatch` to `push`.
-
-## running locally
-
-- install dependencies with `npm run setup`
-- run dev server with `npm run repl` and open `http://localhost:3000/strudel/swatch/`
-
-## tests fail?
-
-Your tests might fail if the code does not follow prettiers format.
-In that case, run `npm run codeformat`. To disable that, remove `npm run format-check` from `test.yml`
-
-## updating your fork
-
-To update your fork, you can pull the main branch and merge it into your `patternuary` branch.

+# @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.
+
+## 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)
