### Changed
### Removed
## [4.3.0]
### Added
- Added documentation (moved from `protocol`)
- `Frac.aes` library for rational numbers
- Added some more meaningful error messages
- Exported several parsing functionalities
- With option `keep_included` it is possible to see which files were included during the parse
- There is a function `run_parser` that be used to evaluate any parsing rule
- Exported parsers: `body`, `type` and `decl`
### Changed
- Performance improvements in the standard library
- Fixed ACI encoder to handle `-` unary operator
- Fixed including by absolute path
- Fixed variant type printing in the ACI error messages
- Fixed pretty printing of combined function clauses
### Removed
- `let` definitions are no longer supported in the toplevel of the contract
- type declarations are no longer supported
## [4.2.0] - 2020-01-15
### Added
- Allow separate entrypoint/function type signature and definition, and pattern
matching in left-hand sides:
```
function
length : list('a) => int
length([]) = 0
length(x :: xs) = 1 + length(xs)
```
- Allow pattern matching in list comprehension generators (filtering out match
failures):
```
function somes(xs : list(option('a))) : list('a) =
[ x | Some(x) <- xs ]
```
- Allow pattern matching in let-bindings (aborting on match failures):
```
function test(m : map(int, int)) =
let Some(x) = Map.lookup(m, 0)
x
```
### Changed
- FATE code generator improvements.
- Bug fix: Handle qualified constructors in patterns.
- Bug fix: Allow switching also on negative numbers.
### Removed
## [4.1.0] - 2019-11-26
### Added
- Support encoding and decoding bit fields in call arguments and results.
### Changed
- Various improvements to FATE code generator.
### Removed
## [4.0.0] - 2019-10-11
### Added
- `Address.to_contract` - casts an address to a (any) contract type.
- Pragma to check compiler version, e.g. `@compiler >= 4.0`.
- Handle numeric escapes, i.e. `"\x19Ethereum Signed Message:\n"`, and similar strings.
- `Bytes.concat` and `Bytes.split` are added to be able to
(de-)construct byte arrays.
- `[a..b]` language construct, returning the list of numbers between
`a` and `b` (inclusive). Returns the empty list if `a` > `b`.
- [Standard libraries](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md)
- Checks that `init` is not called from other functions.
- FATE backend - the compiler is able to produce VM code for both `AEVM` and `FATE`. Many
of the APIs now take `{backend, aevm | fate}` to decide wich backend to produce artifacts
for.
- New builtin functions `Crypto.ecrecover_secp256k1: (hash, bytes(65)) => option(bytes(20))`
and `Crypto.ecverify_secp256k1 : (hash, bytes(20), bytes(65)) => bool` for recovering
and verifying an Ethereum address for a message hash and a signature.
- Sophia supports list comprehensions known from languages like Python, Haskell or Erlang.
Example syntax:
```
[x + y | x <- [1,2,3,4,5], let k = x*x, if (k > 5), y <- [k, k+1, k+2]]
// yields [12,13,14,20,21,22,30,31,32]
```
- A new contract, and endpoint, modifier `payable` is introduced. Contracts, and enpoints,
that shall be able to receive funds should be marked as payable. `Address.is_payable(a)`
can be used to check if an (contract) address is payable or not.
### Changed
- Nice type error if contract function is called as from a namespace.
- Fail on function definitions in contracts other than the main contract.
- Bug fix in variable optimization - don't discard writes to the store/state.
- Bug fixes in error reporting.
- Bug fix in variable liveness analysis for FATE.
- Error messages are changed into a uniform format, and more helpful
messages have been added.
- `Crypto.<hash_fun>` and `String.<hash_fun>` for byte arrays now only
hash the actual byte array - not the internal ABI format.
- More strict checks for polymorphic oracles and higher order oracles
and entrypoints.
- `AENS.claim` is updated with a `NameFee` field - to be able to do
name auctions within contracts.
- Fixed a bug in `Bytes.to_str` for AEVM.
- New syntax for tuple types. Now 0-tuple type is encoded as `unit` instead of `()` and
regular tuples are encoded by interspersing inner types with `*`, for instance `int * string`.
Parens are not necessary. Note it only affects the types, values remain as their were before,
so `(1, "a") : int * string`
- The `AENS.transfer` and `AENS.revoke` functions have been updated to take a name `string`
instead of a name `hash`.
- Fixed a bug where the `AEVM` backend complained about a missing `init` function when
trying to generate calldata from an ACI-generated interface.
- Compiler now returns the ABI-version in the compiler result map.
- Renamed `Crypto.ecverify` and `Crypto.ecverify_secp256k1` into `Crypto.verify_sig` and
`Crypto.verify_sig_secp256k1` respectively.
### Removed
## [3.2.0] - 2019-06-28
### Added
- New builtin function `require : (bool, string) => ()`. Defined as
```
function require(b, err) = if(!b) abort(err)
```
- New builtin functions
```
Bytes.to_str : bytes(_) => string
Bytes.to_int : bytes(_) => int
```
for converting a byte array to a hex string and interpreting it as a
big-endian encoded integer respectively.
### Changed
- Public contract functions must now be declared as *entrypoints*:
```
contract Example =
// Exported
entrypoint exported_fun(x) = local_fun(x)
// Not exported
function local_fun(x) = x
```
Functions in namespaces still use `function` (and `private function` for
private functions).
- The return type of `Chain.block_hash(height)` has changed, it used to
be `int`, where `0` denoted an incorrect height. New return type is
`option(hash)`, where `None` represents an incorrect height.
- Event name hashes now use BLAKE2b instead of Keccak256.
- Fixed bugs when defining record types in namespaces.
- Fixed a bug in include path handling when passing options to the compiler.
### Removed
## [3.1.0] - 2019-06-03
### Added
### Changed
- Keyword `indexed` is now optional for word typed (`bool`, `int`, `address`,
...) event arguments.
- State variable pretty printing now produce `'a, 'b, ...` instead of `'1, '2, ...`.
- ACI is restructured and improved:
- `state` and `event` types (if present) now appear at the top level.
- Namespaces and remote interfaces are no longer ignored.
- All type definitions are included in the interface rendering.
- API functions are renamed, new functions are `contract_interface`
and `render_aci_json`.
- Fixed a bug in `create_calldata`/`to_sophia_value` - it can now handle negative
literals.
### Removed
## [3.0.0] - 2019-05-21
### Added
- `stateful` annotations are now properly enforced. Functions must be marked stateful
in order to update the state or spend tokens.
- Primitives `Contract.creator`, `Address.is_contract`, `Address.is_oracle`,
`Oracle.check` and `Oracle.check_query` has been added to Sophia.
- A byte array type `bytes(N)` has been added to generalize `hash (== bytes(32))` and
`signature (== bytes(64))` and allow for byte arrays of arbitrary fixed length.
- `Crypto.ecverify_secp256k1` has been added.
### Changed
- Address literals (+ Oracle, Oracle query and remote contracts) have been changed
from `#<hex>` to address as `ak_<base58check>`, oracle `ok_<base58check>`,
oracle query `oq_<base58check>` and remote contract `ct_<base58check>`.
- The compilation and typechecking of `letfun` (e.g. `let m(f, xs) = map(f, xs)`) was
not working properly and has been fixed.
### Removed
- `let rec` has been removed from the language, it has never worked.
- The standalone CLI compiler is served in the repo `aeternity/aesophia_cli` and has
been completely removed from `aesophia`.

# 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.
This is the __sophia__ compiler for the æternity system which compiles contracts written in __sophia__ code to the æternity VM code.
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 [Aeternity node](https://github.com/aeternity/aeternity) tests
For more information about æternity smart contracts and the sophia language see [Smart Contracts](https://github.com/aeternity/protocol/blob/master/contracts/contracts.md) and the [Sophia Language](https://github.com/aeternity/protocol/blob/master/contracts/sophia.md).
## Documentation
* [Smart Contracts on aeternity Blockchain](https://github.com/aeternity/protocol/blob/master/contracts/contracts.md).
* [Sophia Documentation](docs/sophia.md).
* [Sophia Standard Library](docs/sophia_stdlib.md).
It is an OTP application written in Erlang and is by default included in
[the æternity node](https://github.com/aeternity/epoch). However, it can
also be included in other systems to compile contracts coded in sophia which
can then be loaded into the æternity system.

#### contract\_interface(aci\_type(), string()) -> {ok, json() | string()} | {error, term()}
#### encode_contract(ContractString) -> {ok,JSONstring} | {error,ErrorString}
Generate the JSON encoding of the interface to a contract. The type definitions
and non-private functions are included in the JSON string.
Types
#### render\_aci\_json(json() | json\_text()) -> string().
``` erlang
ConstractString = contract_string()
JSONstring = json_string()
```
Take a JSON encoding of a contract interface and generate a contract interface
that can be included in another contract.
This is equivalent to `aeso_aci:encode_contract(ConstractString, [])`.
#### encode_contract(ContractString, Options) -> {ok,JSONstring} | {error,ErrorString}
Types
``` erlang
ConstractString = contract_string()
Options = [option()]

#### encode_type(TypeAST) -> JSONstring.
Types
``` erlang
JSONstring = json_string()
```
Generate the JSON encoding of a type from the AST of the type.
#### encode_arg(ArgAST) -> JSONstring.
Types
``` erlang
JSONstring = json_string()
```
Generate the JSON encoding of a function argument from the AST of the argument.
#### encode_stmt(StmtAST) -> JSONstring.
Types
``` erlang

### Notes
The deprecated functions `aseo_aci:encode/2` and `aeso_aci:decode/1` are still available but should not be used.
### Example run
This is an example of using the ACI generator from an Erlang shell. The file
called `aci_test.aes` contains the contract in the description from which we
want to generate files `aci_test.json` which is the JSON encoding of the
contract interface and `aci_test.include` which is the contract definition to
be included inside another contract.
