## Summary We're planning to move the documentation from [https://beta.ruff.rs/docs](https://beta.ruff.rs/docs) to [https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), for a few reasons: 1. We want to remove the `beta` from the domain, as Ruff is no longer considered beta software. 2. We want to migrate to a structure that could accommodate multiple future tools living under one domain. The docs are actually already live at [https://docs.astral.sh/ruff](https://docs.astral.sh/ruff), but later today, I'll add a permanent redirect from the previous to the new domain. **All existing links will continue to work, now and in perpetuity.** This PR contains the code changes necessary for the updated documentation. As part of this effort, I moved the playground and documentation from my personal Cloudflare account to our team Cloudflare account (hence the new `--project-name` references). After merging, I'll also update the secrets on this repo.

# Preview
|
|
|
|
Ruff includes an opt-in preview mode to provide an opportunity for community feedback and increase confidence that
|
|
changes are a net-benefit before enabling them for everyone.
|
|
|
|
Preview mode enables a collection of newer rules and fixes that are considered experimental or unstable.
|
|
|
|
## Enabling preview mode
|
|
|
|
Preview mode can be enabled with the `--preview` flag on the CLI or by setting `preview = true` in your Ruff
|
|
configuration file (e.g. `pyproject.toml`).
|
|
|
|
## Using rules that are in preview
|
|
|
|
If a rule is marked as preview, it can only be selected if preview mode is enabled. For example, consider a
|
|
hypothetical rule, `HYP001`. If `HYP001` were in preview, it would _not_ be enabled by adding following to your
|
|
`pyproject.toml`:
|
|
|
|
```toml
|
|
[tool.ruff]
|
|
extend-select = ["HYP001"]
|
|
```
|
|
|
|
It also would _not_ be enabled by selecting the `HYP` category, like so:
|
|
|
|
```toml
|
|
[tool.ruff]
|
|
extend-select = ["HYP"]
|
|
```
|
|
|
|
Similarly, it would _not_ be enabled via the `ALL` selector:
|
|
|
|
```toml
|
|
[tool.ruff]
|
|
select = ["ALL"]
|
|
```
|
|
|
|
However, it would be enabled in any of the above cases if you you enabled preview in your configuration file:
|
|
|
|
```toml
|
|
[tool.ruff]
|
|
extend-select = ["HYP"]
|
|
preview = true
|
|
```
|
|
|
|
Or, if you provided the `--preview` CLI flag.
|
|
|
