# aesophia

This is the **sophia** compiler for the æternity system which compiles contracts written in **sophia** to [FATE](https://github.com/aeternity/protocol/blob/master/contracts/fate.md) instructions.

The compiler is currently being used three places

* [The command line compiler](https://github.com/aeternity/aesophia_cli)
* [The HTTP compiler](https://github.com/aeternity/aesophia_http)
* In [æternity node](https://github.com/aeternity/aeternity) tests

## Versioning

Versioning should follow the [semantic versioning](https://semver.org/spec/v2.0.0) guidelines. Id est, given a version number MAJOR.MINOR.PATCH, increment the:

* MAJOR version when you make incompatible API changes
* MINOR version when you add functionality in a backwards compatible manner
* PATCH version when you make backwards compatible bug fixes

## Interface Modules

The basic modules for interfacing the compiler:

* [aeso\_compiler: the Sophia compiler](/developer-documentation/aesophia/docs/aeso_compiler.md)
* [aeso\_aci: the ACI interface](/developer-documentation/aesophia/docs/aeso_aci.md)
