## Why is it called salsa?
I like salsa! Don't you?! Well, ok, there's a bit more to it. The
underlying algorithm for figuring out which bits of code need to be
re-executed after any given change is based on the algorithm used in
rustc. Michael Woerister and I first described the rustc algorithm in
terms of two colors, red and green, and hence we called it the
"red-green algorithm". This made me think of the New Mexico State
Question --- ["Red or green?"][nm] --- which refers to chile
(salsa). Although this version no longer uses colors (we borrowed
revision counters from Glimmer, instead), I still like the name.
[nm]: https://www.sos.state.nm.us/about-new-mexico/state-question/
## What is the relationship between salsa and an Entity-Component System (ECS)?
You may have noticed that Salsa "feels" a lot like an ECS in some
ways. That's true -- Salsa's queries are a bit like *components* (and
the keys to the queries are a bit like *entities*). But there is one
big difference: **ECS is -- at its heart -- a mutable system**. You
can get or set a component of some entity whenever you like. In
contrast, salsa's queries **define "derived values" via pure
computations**.
Partly as a consequence, ECS doesn't handle incremental updates for
you. When you update some component of some entity, you have to ensure
that other entities' components are updated appropriately.
Finally, ECS offers interesting metadata and "aspect-like" facilities,
such as iterating over all entities that share certain components.
Salsa has no analogue to that.

*A generic framework for on-demand, incrementalized computation.*
## Obligatory warning
Very much a WORK IN PROGRESS at this point.
## Credits
This system is heavily inspired by [adapton](http://adapton.org/), [glimmer](https://github.com/glimmerjs/glimmer-vm), and rustc's query
system. So credit goes to Eduard-Mihai Burtescu, Matthew Hammer,
Yehuda Katz, and Michael Woerister.
## Key idea
The key idea of `salsa` is that you define your program as a set of
**queries**. Every query is used like function `K -> V` that maps from
some key of type `K` to a value of type `V`. Queries come in two basic
varieties:
- **Inputs**: the base inputs to your system. You can change these
whenever you like.
- **Functions**: pure functions (no side effects) that transform your
inputs into other values. The results of queries are memoized to
avoid recomputing them a lot. When you make changes to the inputs,
we'll figure out (fairly intelligently) when we can re-use these
memoized values and when we have to recompute them.
## Want to learn more?
To learn more about Salsa, try one of the following:
- read the [heavily commented examples](https://github.com/salsa-rs/salsa/tree/master/examples);
- check out the [Salsa book](https://salsa-rs.github.io/salsa);
- [中文版](https://rust-chinese-translation.github.io/salsa-book)
- watch one of our [videos](https://salsa-rs.github.io/salsa/videos.html).
## Getting in touch
The bulk of the discussion happens in the [issues](https://github.com/salsa-rs/salsa/issues)
and [pull requests](https://github.com/salsa-rs/salsa/pulls),
but we have a [zulip chat](https://salsa.zulipchat.com/) as well.
## Contributing
To create a release and publish to crates.io, update the `version` field in Cargo.toml.
After pushed, GitHub Actions will publish the crates to crates.io automatically.

- **Breaking change:** adopt the new `Durability` API proposed in [RFC #6]
- this replaces and generalizes the existing concepts of constants
- **Breaking change:** remove "volatile" queries
- instead, create a normal query which invokes the
`report_untracked_read` method on the salsa runtime
- introduce "slots", an optimization to salsa's internal workings
- document `#[salsa::requires]` attribute, which permits private dependencies
- Adopt `AtomicU64` for `runtimeId` (#182)
- use `ptr::eq` and `ptr::hash` for readability
- upgrade parking lot, rand dependencies
