## Move to codeberg
We are currently in the process of moving from github to codeberg -- not everything is working, please bear with us.
To update your local clone, you can run this command:
```
git remote set-url origin git@codeberg.org:uzu/strudel.git
```
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.

## 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.
## Report a Bug
If you've found a bug, or some behaviour that does not seem right, you are welcome to file an [issue](https://codeberg.org/uzu/strudel/issues).

/***
* 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!
