Along with many other live coding projects, we have moved from Microsoft's Github platform to Codeberg for ethical reasons. Please don't fork the project back to github.

## Propose a Feature
If you want a specific feature that is not part of strudel yet, feel free to use one of the communication channels above. Please bear in mind that this is a free/open source project, oriented around collaborative discussion. Maybe you even want to help with the implementation of that feature!
## Contribute a feature
Pull requests welcome! Consider starting with discussion or proof-of-concept first, rather than do loads of work on something and then find it doesn't fit the collective goals of the project, or something like that.
At the time of writing we have a PR backlog, and generally prioritise bugfixes and contributions that have arisen through community discussion.
### AI/LLM policy
Strudel is a project handmade by humans, with thought and nuance.
If you have used LLMs (so called 'AI'), please detail that in the pull request. We are still developing our response to the onslaught of LLM technology, but for practical and legal reasons are currently not accepting wholly LLM-generated code. We are also not accepting PRs that add LLM features to strudel itself.
There are #llm-chat and #llm-share channels on our discord. Please do not discuss or share LLM-related things outside of those channels.

/***
* Allows you to switch a pattern between different 'timelines'. This is particularly useful when
* live coding, for example when you want to cue a pattern up to play from its start.
*
* Timelines are specified by number, so that if you had a pattern like
* `n("<0 1 2 3>").s("num").timeline(1)` playing, then changed the '1'
* to '2', it would always align '0' to the nearest cycle. You will likely want to trigger
* an evaluation a little bit before the cycle starts, to avoid missing events.
*
* After the first use, a timeline will continue with the same 'offset'. That is, if you change
* a pattern without changing its timeline number, it will stay on that timeline without resetting.
*
* Rather than incrementing a timeline to reset it, it's easier to negate it, e.g. by switching between `-2`
* and `2`. This is because when you negate a timeline it will always reset.
*
* You can also pattern the timeline if you want, to create strange resetting patterns.
* @param {number | Pattern} timeline The timeline that the pattern should play on.
* @example
* n("<0 1 2 3>(3,8)")
* .sound("num")
* // resets the timeline every two cycles, by negating the timeline.
* // in a lot of cases this will be edited by a human live coder
* // rather than patterned!

### --port
Now open Supercollider (with the super dirt startup file)
By default it will use port 57120 for the osc client, which is what [superdirt](https://github.com/musikinformatik/SuperDirt) uses. You can change it via the `--port` option:
```sh
npx @strudel/osc --port 7771 # classic dirt
```
### --debug
To log all incoming osc messages, add the `--debug` flag:
```sh
npx @strudel/osc --debug
```
## Usage in Strudel
To test it in strudel, you have can use `all(osc)` to send all events through osc:
Now open the REPL and type:
```js
$: s("bd*4")
all(osc)
s("<bd sd> hh").osc()
```
[open in repl](https://strudel.cc/#JDogcygiYmQqNCIpCgphbGwob3NjKQ%3D%3D)
or just [click here](https://strudel.cc/#cygiPGJkIHNkPiBoaCIpLm9zYygp)...
You can read more about [how to use Superdirt with Strudel](https://strudel.cc/learn/input-output/#oscsuperdirtstrudeldirt) in the tutorial.
