## Aqua
|
||
|
||
[](https://github.com/fluencelabs/aqua/actions/workflows/release.yml)
|
||
|
||
Aqua is a new-gen language for distributed systems.
|
||
|
||
Aqua programs are executed on many peers, sequentially
|
||
or in parallel, forming a single-use coordination network.
|
||
|
||
Aqua's runtime is heterogeneous: it includes browsers, servers, devices, all involved in solving a single task.
|
||
Therefore, Aqua scripts are compiled into several targets at once, with AIR and Typescript as a default.
|
||
|
||
## Using Aqua
|
||
|
||
Please refer to [aqua-playground](https://github.com/fluencelabs/aqua-playground) to learn how to use Aqua.
|
||
|
||
## Compiler CLI
|
||
|
||
To build the Aqua compiler, clone the repo & run `sbt assembly`,
|
||
or simply download the latest JAR file from the [releases](https://github.com/fluencelabs/aqua/releases) page.
|
||
|
||
It requires `java` to run Aqua compiler from the command line:
|
||
|
||
```commandline
|
||
java -jar aqua-cli-%version_number%.jar -i path/to/input/dir -o path/to/output/dir
|
||
```
|
||
|
||
Input directory should contain files with `aqua` scripts.
|
||
|
||
## Repository structure
|
||
|
||
- **[types](./types)** – data types, arrows, stream types definitions and variance
|
||
- **[parser](./parser)** - parser, takes source text and produces a source AST
|
||
- **[model](./model)** - middle-end, internal representation of the code, optimizations and transfromations
|
||
- **[semantics](./semantics)** - rules to convert source AST into the model
|
||
- **[linker](./linker)** - checks dependencies between modules, builds and combines an abstract dependencies tree
|
||
- **[backend/air](./backend/air)** – generates AIR code from the middle-end model
|
||
- **[backend/ts](./backend/ts)** - generates AIR code and Typescript wrappers for use with Fluence JS SDK
|
||
- **[cli](./cli)** - CLI interface
