## [Unreleased]
### Added
- Compiler warnings for the follwing: shadowing, negative spends, division by zero, unused functions, unused includes, unused stateful annotations, unused variables, unused parameters, unused user-defined type, dead return value.
- The pipe operator |>
```
[1, 2, 3] |> List.first |> Option.is_some // Option.is_some(List.first([1, 2, 3]))
```
- Allow binary operators to be used as lambdas
```
function sum(l : list(int)) : int = foldl((+), 0, l)
function logical_and(x, y) = (&&)(x, y)
```
### Changed
- Error messages have been restructured (less newlines) to provide more unified errors. Also `pp_oneline/1` has been added.
- Ban empty record definitions (e.g. `record r = {}` would give an error).
### Removed
- Support for AEVM has been entirely wiped
## [6.1.0] - 2021-10-20
### Added
- `Bitwise` stdlib
- `Set` stdlib
- `Option.force_msg`
- Loading namespaces into the current scope (e.g. `using Pair`)
- Assign patterns to variables (e.g. `let x::(t = y::_) = [1, 2, 3, 4]` where `t == [2, 3, 4]`)
- Add builtin types (`AENS.name, AENS.pointee, Chain.ttl, Chain.base_tx, Chain.ga_meta_tx, Chain.paying_for_tx`) to
the calldata and result decoder
- Patterns guards
```
switch(x)
a::[] | a > 10 => 1
_ => 2
```
```
function
f(a::[]) | a > 10 = 1
f(_) = 2
```
### Changed
- Fixed the ACI renderer, it shouldn't drop the `stateful` modifier
## [6.0.2] 2021-07-05
### Changed
- `List.from_to_step` now forbids non-positive step (this change does
*not* alter the behavior of the previously deployed contracts)
- Fixed leaking state between contracts
## [6.0.1] 2021-06-24
### Changed
- Fixed a bug in calldata encoding for contracts containing multiple contracts
- Fixed a missing `include` in the `Frac` standard library
## [6.0.0] 2021-05-26
### Added
- Child contracts
- `Chain.clone`
- `Chain.create`
- `Chain.bytecode_hash`
- Minor support for variadic functions
- `void` type that represents an empty type
- `Call.fee` builtin
### Changed
- Contract interfaces must be now invocated by `contract interface` keywords
- `main` keyword to indicate the main contract in case there are child contracts around
- `List.sum` and `List.product` no longer use `List.foldl`
### Removed
## [5.0.0] 2021-04-30
### Added
- A new and improved [`String` standard library](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md#string)
has been added. Use it by `include "String.aes"`. It includes functions for
turning strings into lists of characters for detailed manipulation. For
example:
```
include "String.aes"
contract C =
entrypoint filter_all_a(s: string) : string =
String.from_list(List.filter((c : char) => c != 'a', String.to_list(s)))
```
will return a list with all `a`'s removed.
There are also convenience functions `split`, `concat`, `to_upper`,
`to_lower`, etc.
All String functions in FATEv2 operate on unicode code points.
- Operations for pairing-based cryptography has been added the operations
are in the standard library [BLS12_381](https://github.com/aeternity/aesophia/blob/master/docs/sophia_stdlib.md#bls12_381).
With these operations it is possible to do Zero Knowledge-proofs, etc.
The operations are for the BLS12-381 curve (as the name suggests).
- Calls to functions in other contracts (i.e. _remote calls_) can now be
[`protected`](https://github.com/aeternity/aesophia/blob/master/docs/sophia.md#protected-contract-calls).
If a contract call fails for any reason (for instance, the remote contract
crashes or runs out of gas, or the entrypoint doesn't exist or has the
wrong type) the parent call also fails. To make it possible to recover
from failures, contract calls takes a named argument `protected : bool`
(default `false`).
If `protected = true` the result of the contract call is wrapped in an
`option`, and `Some(value)` indicates a succesful execution and `None`
indicates that the contract call failed. Note: any gas consumed until
the failure is still charged, but all side effects in the remote
contract are rolled back on failure.
- A new chain operation [`AENS.update`](https://github.com/aeternity/aesophia/blob/master/docs/sophia.md#aens-interface)
is supported.
- New chain exploring operations `AENS.lookup` and `Oracle.expiry` to
look up an AENS record and the expiry of an Oracle respectively, are added.
- Transaction introspection (`Auth.tx`) has been added. When a Generalized
account is authorized, the authorization function needs access to the
transaction (and the transaction hash) for the wrapped transaction. The
transaction and the transaction hash is available `Auth.tx`, it is only
available during authentication if invoked by a normal contract call
it returns `None`. Example:
```
switch(Auth.tx)
None => abort("Not in Auth context")
Some(tx0) =>
switch(tx0.tx)
Chain.SpendTx(_, amount, _) => amount > 400
Chain.ContractCallTx(_, _) => true
_ => false
```
- A debug mode is a added to the compiler. Right now its only use is to
turn off hermetization.
### Changed
- The function `Chain.block_hash(height)` is now (in FATEv2) defined for
the current height - this used to be an error.
- Standard library: Sort is optimized to do `mergesort` and a `contains`
function is added.
- Improved type errors and explicit errors for some syntax errors (empty code
blocks, etc.).
- Compiler optimization: The ACI is generated alongside bytecode. This means
that multiple compiler passes can be avoided.
- Compiler optimization: Improved parsing (less stack used when transpiled).
- A bug where constraints were handled out of order fixed.
- Fixed calldata decoding for singleton records.
- Improved the documentation w.r.t. signatures, especially stressing the fact that
the network ID is a part of what is signed.

# Introduction
Sophia is a functional language designed for smart contract development. It is strongly typed and has
restricted mutable state.
Sophia is customized for smart contracts, which can be published
to a blockchain. Thus some features of conventional
languages, such as floating point arithmetic, are not present in Sophia, and
some [æternity blockchain](https://aeternity.com) specific primitives, constructions and types have been added.
!!! Note
- For rapid prototyping of smart contracts check out [AEstudio](https://studio.aepps.com/)!
- For playing around and diving deeper into the language itself check out the [REPL](https://repl.aeternity.io/)!

# Features
## Contracts
The main unit of code in Sophia is the *contract*.
- A contract implementation, or simply a contract, is the code for a
smart contract and consists of a list of types, entrypoints and local
functions. Only the entrypoints can be called from outside the contract.
- A contract instance is an entity living on the block chain (or in a state
channel). Each instance has an address that can be used to call its
entrypoints, either from another contract or in a call transaction.
- A contract may define a type `state` encapsulating its local
state. When creating a new contract the `init` entrypoint is executed and the
state is initialized to its return value.
The language offers some primitive functions to interact with the blockchain and contracts.
Please refer to the [Chain](sophia_stdlib.md#chain), [Contract](sophia_stdlib.md#contract)
and the [Call](sophia_stdlib.md#call) namespaces in the documentation.
### Calling other contracts
To call a function in another contract you need the address to an instance of
the contract. The type of the address must be a contract type, which consists
of a number of type definitions and entrypoint declarations. For instance,
```sophia
// A contract type
contract interface VotingType =
entrypoint vote : string => unit
```
Now given contract address of type `VotingType` you can call the `vote`
entrypoint of that contract:
```sophia
contract VoteTwice =
entrypoint voteTwice(v : VotingType, alt : string) =
v.vote(alt)
v.vote(alt)
```
Contract calls take two optional named arguments `gas : int` and `value : int`
that lets you set a gas limit and provide tokens to a contract call. If omitted
the defaults are no gas limit and no tokens. Suppose there is a fee for voting:
```sophia
entrypoint voteTwice(v : VotingType, fee : int, alt : string) =
v.vote(value = fee, alt)
v.vote(value = fee, alt)
```
Named arguments can be given in any order.
Note that reentrant calls are not permitted. In other words, when calling
another contract it cannot call you back (directly or indirectly).
To construct a value of a contract type you can give a contract address literal
(for instance `ct_2gPXZnZdKU716QBUFKaT4VdBZituK93KLvHJB3n4EnbrHHw4Ay`), or
convert an account address to a contract address using `Address.to_contract`.
Note that if the contract does not exist, or it doesn't have the entrypoint, or
the type of the entrypoint does not match the stated contract type, the call
fails.
To recover the underlying `address` of a contract instance there is a field
`address : address`. For instance, to send tokens to the voting contract (given that it is payable)
without calling it you can write
```sophia
entrypoint pay(v : VotingType, amount : int) =
Chain.spend(v.address, amount)
```
### Protected contract calls
If a contract call fails for any reason (for instance, the remote contract
crashes or runs out of gas, or the entrypoint doesn't exist or has the wrong
type) the parent call also fails. To make it possible to recover from failures,
contract calls takes a named argument `protected : bool` (default `false`).
The protected argument must be a literal boolean, and when set to `true`
changes the type of the contract call, wrapping the result in an `option` type.
If the call fails the result is `None`, otherwise it's `Some(r)` where `r` is
the return value of the call.
```sophia
contract interface VotingType =
entrypoint : vote : string => unit
contract Voter =
entrypoint tryVote(v : VotingType, alt : string) =
switch(v.vote(alt, protected = true) : option(unit))
None => "Voting failed"
Some(_) => "Voting successful"
```
Any gas that was consumed by the contract call before the failure stays
consumed, which means that in order to protect against the remote contract
running out of gas it is necessary to set a gas limit using the `gas` argument.
However, note that errors that would normally consume all the gas in the
transaction still only uses up the gas spent running the contract.
Any side effects (state change, token transfers, etc.) made by a failing
protected call is rolled back, just like they would be in the unprotected case.
### Contract factories and child contracts
Since the version 6.0.0 Sophia supports deploying contracts by other
contracts. This can be done in two ways:
- Contract cloning via [`Chain.clone`](sophia_stdlib.md#clone)
- Direct deploy via [`Chain.create`](sophia_stdlib.md#create)
These functions take variable number of arguments that must match the created
contract's `init` function. Beside that they take some additional named
arguments please refer to their documentation for the details.
While `Chain.clone` requires only a `contract interface` and a living instance
of a given contract on the chain, `Chain.create` needs a full definition of a
to-create contract defined by the standard `contract` syntax, for example
```sophia
contract IntHolder =
type state = int
entrypoint init(x) = x
entrypoint get() = state
main contract IntHolderFactory =
stateful entrypoint new(x : int) : IntHolder =
let ih = Chain.create(x) : IntHolder
ih
```
In case of a presence of child contracts (`IntHolder` in this case), the main
contract must be pointed out with the `main` keyword as shown in the example.
## Mutable state
Sophia does not have arbitrary mutable state, but only a limited form of state
associated with each contract instance.
- Each contract defines a type `state` encapsulating its mutable state.
The type `state` defaults to the `unit`.
- The initial state of a contract is computed by the contract's `init`
function. The `init` function is *pure* and returns the initial state as its
return value.
If the type `state` is `unit`, the `init` function defaults to returning the value `()`.
At contract creation time, the `init` function is executed and
its result is stored as the contract state.
- The value of the state is accessible from inside the contract
through an implicitly bound variable `state`.
- State updates are performed by calling a function `put : state => unit`.
- Aside from the `put` function (and similar functions for transactions
and events), the language is purely functional.
- Functions modifying the state need to be annotated with the `stateful` keyword (see below).
To make it convenient to update parts of a deeply nested state Sophia
provides special syntax for map/record updates.
### Stateful functions
Top-level functions and entrypoints must be annotated with the
`stateful` keyword to be allowed to affect the state of the running contract.
For instance,
```sophia
stateful entrypoint set_state(s : state) =
put(s)
```
Without the `stateful` annotation the compiler does not allow the call to
`put`. A `stateful` annotation is required to
* Use a stateful primitive function. These are
- `put`
- `Chain.spend`
- `Oracle.register`
- `Oracle.query`
- `Oracle.respond`
- `Oracle.extend`
- `AENS.preclaim`
- `AENS.claim`
- `AENS.transfer`
- `AENS.revoke`
- `AENS.update`
* Call a `stateful` function in the current contract
* Call another contract with a non-zero `value` argument.
A `stateful` annotation *is not* required to
* Read the contract state.
* Issue an event using the `event` function.
* Call another contract with `value = 0`, even if the called function is stateful.
## Payable
### Payable contracts
A concrete contract is by default *not* payable. Any attempt at spending to such
a contract (either a `Chain.spend` or a normal spend transaction) will fail. If a
contract shall be able to receive funds in this way it has to be declared `payable`:
```sophia
// A payable contract
payable contract ExampleContract =
stateful entrypoint do_stuff() = ...
```
If in doubt, it is possible to check if an address is payable using
`Address.is_payable(addr)`.
### Payable entrypoints
A contract entrypoint is by default *not* payable. Any call to such a function
(either a [Remote call](#calling-other-contracts) or a contract call transaction)
that has a non-zero `value` will fail. Contract entrypoints that should be called
with a non-zero value should be declared `payable`.
```sophia
payable stateful entrypoint buy(to : address) =
if(Call.value > 42)
transfer_item(to)
else
abort("Value too low")
```
## Namespaces
Code can be split into libraries using the `namespace` construct. Namespaces
can appear at the top-level and can contain type and function definitions, but
not entrypoints. Outside the namespace you can refer to the (non-private) names
by qualifying them with the namespace (`Namespace.name`).
For example,
```sophia
namespace Library =
type number = int
function inc(x : number) : number = x + 1
contract MyContract =
entrypoint plus2(x) : Library.number =
Library.inc(Library.inc(x))
```
Functions in namespaces have access to the same environment (including the
`Chain`, `Call`, and `Contract`, builtin namespaces) as function in a contract,
with the exception of `state`, `put` and `Chain.event` since these are
dependent on the specific state and event types of the contract.
To avoid mentioning the namespace every time it is used, Sophia allows
including the namespace in the current scope with the `using` keyword:
```
include "Pair.aes"
using Pair
contract C =
type state = int
entrypoint init() =
let p = (1, 2)
fst(p) // this is the same as Pair.fst(p)
```
It is also possible to make an alias for the namespace with the `as` keyword:
```
include "Pair.aes"
contract C =
using Pair as P
type state = int
entrypoint init() =
let p = (1, 2)
P.fst(p) // this is the same as Pair.fst(p)
```
Having the same alias for multiple namespaces is possible and it allows
referening functions that are defined in different namespaces and have
different names with the same alias:
```
namespace Xa = function f() = 1
namespace Xb = function g() = 2
contract Cntr =
using Xa as A
using Xb as A
type state = int
entrypoint init() = A.f() + A.g()
```
Note that using functions with the same name would result in an ambiguous name
error:
```
namespace Xa = function f() = 1
namespace Xb = function f() = 2
contract Cntr =
using Xa as A
using Xb as A
type state = int
// the next line has an error because f is defined in both Xa and Xb
entrypoint init() = A.f()
```
Importing specific parts of a namespace or hiding these parts can also be
done like this:
```
using Pair for [fst, snd] // this will only import fst and snd
using Triple hiding [fst, snd] // this will import everything except for fst and snd
```
Note that it is possible to use a namespace in the top level of the file, in the
contract level, namespace level, or in the function level.
## Splitting code over multiple files
Code from another file can be included in a contract using an `include`
statement. These must appear at the top-level (outside the main contract). The
included file can contain one or more namespaces and abstract contracts. For
example, if the file `library.aes` contains
```sophia
namespace Library =
function inc(x) = x + 1
```
you can use it from another file using an `include`:
```sophia
include "library.aes"
contract MyContract =
entrypoint plus2(x) = Library.inc(Library.inc(x))
```
This behaves as if the contents of `library.aes` was textually inserted into
the file, except that error messages will refer to the original source
locations. The language will try to include each file at most one time automatically,
so even cyclic includes should be working without any special tinkering.
## Standard library
Sophia offers [standard library](sophia_stdlib.md) which exposes some
primitive operations and some higher level utilities. The builtin
namespaces like `Chain`, `Contract`, `Map`
are included by default and are supported internally by the compiler.
Others like `List`, `Frac`, `Option` need to be manually included using the
`include` directive. For example
```sophia
include "List.aes"
include "Pair.aes"
-- Map is already there!
namespace C =
entrypoint keys(m : map('a, 'b)) : list('a) =
List.map(Pair.fst, (Map.to_list(m)))
```
## Types

## Arithmetic
Sophia integers (`int`) are represented by arbitrary-sized signed words and support the following
arithmetic operations:
- addition (`x + y`)
- subtraction (`x - y`)
- multiplication (`x * y`)
- division (`x / y`), truncated towards zero
- remainder (`x mod y`), satisfying `y * (x / y) + x mod y == x` for non-zero `y`
- exponentiation (`x ^ y`)
All operations are *safe* with respect to overflow and underflow.
The division and modulo operations throw an arithmetic error if the
right-hand operand is zero.
## Bit fields
Sophia integers do not support bit arithmetic. Instead there is a separate
type `bits`. See the standard library [documentation](sophia_stdlib.md#bits).
A bit field can be of arbitrary size (but it is still represented by the
corresponding integer, so setting very high bits can be expensive).
## Type aliases
Type aliases can be introduced with the `type` keyword and can be
parameterized. For instance
```sophia
type number = int
type string_map('a) = map(string, 'a)
```
A type alias and its definition can be used interchangeably. Sophia does not support
higher-kinded types, meaning that following type alias is invalid: `type wrap('f, 'a) = 'f('a)`
## Algebraic data types
Sophia supports algebraic data types (variant types) and pattern matching. Data
types are declared by giving a list of constructors with
their respective arguments. For instance,
```sophia
datatype one_or_both('a, 'b) = Left('a) | Right('b) | Both('a, 'b)
```
Elements of data types can be pattern matched against, using the `switch` construct:
```sophia
function get_left(x : one_or_both('a, 'b)) : option('a) =
switch(x)
Left(x) => Some(x)
Right(_) => None
Both(x, _) => Some(x)
```
or directly in the left-hand side:
```sophia
function
get_left : one_or_both('a, 'b) => option('a)
get_left(Left(x)) = Some(x)
get_left(Right(_)) = None
get_left(Both(x, _)) = Some(x)
```
*NOTE: Data types cannot currently be recursive.*
Sophia also supports the assignment of patterns to variables:
```sophia
function f(x) = switch(x)
h1::(t = h2::_) => (h1 + h2)::t // same as `h1::h2::k => (h1 + h2)::h2::k`
_ => x
function g(p : int * option(int)) : int =
let (a, (o = Some(b))) = p // o is equal to Pair.snd(p)
b
```
Guards are boolean expressions that can be used on patterns in both switch
statements and functions definitions. If a guard expression evaluates to
`true`, then the corresponding body will be used. Otherwise, the next pattern
will be checked:
```sophia
function get_left_if_positive(x : one_or_both(int, 'b)) : option(int) =
switch(x)
Left(x) | x > 0 => Some(x)
Both(x, _) | x > 0 => Some(x)
_ => None
```
```sophia
function
get_left_if_positive : one_or_both(int, 'b) => option(int)
get_left_if_positive(Left(x)) | x > 0 = Some(x)
get_left_if_positive(Both(x, _)) | x > 0 = Some(x)
get_left_if_positive(_) = None
```
Guards cannot be stateful even when used inside a stateful function.
## Lists
A Sophia list is a dynamically sized, homogenous, immutable, singly
linked list. A list is constructed with the syntax `[1, 2, 3]`. The
elements of a list can be any of datatype but they must have the same
type. The type of lists with elements of type `'e` is written
`list('e)`. For example we can have the following lists:
```sophia
[1, 33, 2, 666] : list(int)
[(1, "aaa"), (10, "jjj"), (666, "the beast")] : list(int * string)
[{[1] = "aaa", [10] = "jjj"}, {[5] = "eee", [666] = "the beast"}] : list(map(int, string))
```
New elements can be prepended to the front of a list with the `::`
operator. So `42 :: [1, 2, 3]` returns the list `[42, 1, 2, 3]`. The
concatenation operator `++` appends its second argument to its first
and returns the resulting list. So concatenating two lists
`[1, 22, 33] ++ [10, 18, 55]` returns the list `[1, 22, 33, 10, 18, 55]`.
Sophia supports list comprehensions known from languages like Python, Haskell or Erlang.
Example syntax:
```sophia
[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]
```
Lists can be constructed using the range syntax using special `..` operator:
```sophia
[1..4] == [1,2,3,4]
```
The ranges are always ascending and have step equal to 1.
Please refer to the [standard library](sophia_stdlib.md#list) for the predefined functionalities.
## Maps and records
A Sophia record type is given by a fixed set of fields with associated,
possibly different, types. For instance
```sophia
record account = { name : string,
balance : int,
history : list(transaction) }
```
Maps, on the other hand, can contain an arbitrary number of key-value bindings,
but of a fixed type. The type of maps with keys of type `'k` and values of type
`'v` is written `map('k, 'v)`. The key type can be any type that does not
contain a map or a function type.
Please refer to the [standard library](sophia_stdlib.md#map) for the predefined functionalities.
### Constructing maps and records
A value of record type is constructed by giving a value for each of the fields.
For the example above,
```sophia
function new_account(name) =
{name = name, balance = 0, history = []}
```
Maps are constructed similarly, with keys enclosed in square brackets
```sophia
function example_map() : map(string, int) =
{["key1"] = 1, ["key2"] = 2}
```
The empty map is written `{}`.
### Accessing values
Record fields access is written `r.f` and map lookup `m[k]`. For instance,
```sophia
function get_balance(a : address, accounts : map(address, account)) =
accounts[a].balance
```
Looking up a non-existing key in a map results in contract execution failing. A
default value to return for non-existing keys can be provided using the syntax
`m[k = default]`. See also `Map.member` and `Map.lookup` below.
### Updating a value
Record field updates are written `r{f = v}`. This creates a new record value
which is the same as `r`, but with the value of the field `f` replaced by `v`.
Similarly, `m{[k] = v}` constructs a map with the same values as `m` except
that `k` maps to `v`. It makes no difference if `m` has a mapping for `k` or
not.
It is possible to give a name to the old value of a field or mapping in an
update: instead of `acc{ balance = acc.balance + 100 }` it is possible to write
`acc{ balance @ b = b + 100 }`, binding `b` to `acc.balance`. When giving a
name to a map value (`m{ [k] @ x = v }`), the corresponding key must be present
in the map or execution fails, but a default value can be provided:
`m{ [k = default] @ x = v }`. In this case `x` is bound to `default` if
`k` is not in the map.
Updates can be nested:
```sophia
function clear_history(a : address, accounts : map(address, account)) : map(address, account) =
accounts{ [a].history = [] }
```
This is equivalent to `accounts{ [a] @ acc = acc{ history = [] } }` and thus
requires `a` to be present in the accounts map. To have `clear_history` create
an account if `a` is not in the map you can write (given a function `empty_account`):
```sophia
accounts{ [a = empty_account()].history = [] }
```
### Map implementation
Internally in the VM maps are implemented as hash maps and support fast lookup
and update. Large maps can be stored in the contract state and the size of the
map does not contribute to the gas costs of a contract call reading or updating
it.
## Strings
There is a builtin type `string`, which can be seen as an array of bytes.
Strings can be compared for equality (`==`, `!=`), used as keys in maps and
records, and used in builtin functions `String.length`, `String.concat` and
the hash functions described below.
Please refer to the `String` [library documentation](sophia_stdlib.md#string).
## Chars
There is a builtin type `char` (the underlying representation being an integer),
mainly used to manipulate strings via `String.to_list`/`String.from_list`.
Characters can also be introduced as character literals (`'x', '+', ...).
Please refer to the `Char` [library documentation](sophia_stdlib.md#char).
## Byte arrays
Byte arrays are fixed size arrays of 8-bit integers. They are described in hexadecimal system,
for example the literal `#cafe` creates a two-element array of bytes `ca` (202) and `fe` (254)
and thus is a value of type `bytes(2)`.
Please refer to the `Bytes` [library documentation](sophia_stdlib.md#bytes).
## Cryptographic builtins
Libraries [Crypto](sophia_stdlib.md#crypto) and [String](sophia_stdlib.md#string) provide functions to
hash objects, verify signatures etc. The `hash` is a type alias for `bytes(32)`.
## Authorization interface
When a Generalized account is authorized, the authorization function needs
access to the transaction and the transaction hash for the wrapped transaction. (A `GAMetaTx`
wrapping a transaction.) The transaction and the transaction hash is available in the primitive
`Auth.tx` and `Auth.tx_hash` respectively, they are *only* available during authentication if invoked by a
normal contract call they return `None`.
## Oracle interface
You can attach an oracle to the current contract and you can interact with oracles
through the Oracle interface.
For a full description of how Oracle works see
[Oracles](https://github.com/aeternity/protocol/blob/master/oracles/oracles.md#oracles).
For a functionality documentation refer to the [standard library](sophia_stdlib.md#oracle).
### Example
Example for an oracle answering questions of type `string` with answers of type `int`:
```sophia
contract Oracles =
stateful entrypoint registerOracle(acct : address,
sign : signature, // Signed network id + oracle address + contract address
qfee : int,
ttl : Chain.ttl) : oracle(string, int) =
Oracle.register(acct, signature = sign, qfee, ttl)
entrypoint queryFee(o : oracle(string, int)) : int =
Oracle.query_fee(o)
payable stateful entrypoint createQuery(o : oracle_query(string, int),
q : string,
qfee : int,
qttl : Chain.ttl,
rttl : int) : oracle_query(string, int) =
require(qfee =< Call.value, "insufficient value for qfee")
Oracle.query(o, q, qfee, qttl, RelativeTTL(rttl))
stateful entrypoint extendOracle(o : oracle(string, int),
ttl : Chain.ttl) : unit =
Oracle.extend(o, ttl)
stateful entrypoint signExtendOracle(o : oracle(string, int),
sign : signature, // Signed network id + oracle address + contract address
ttl : Chain.ttl) : unit =
Oracle.extend(o, signature = sign, ttl)
stateful entrypoint respond(o : oracle(string, int),
q : oracle_query(string, int),
sign : signature, // Signed network id + oracle query id + contract address
r : int) =
Oracle.respond(o, q, signature = sign, r)
entrypoint getQuestion(o : oracle(string, int),
q : oracle_query(string, int)) : string =
Oracle.get_question(o, q)
entrypoint hasAnswer(o : oracle(string, int),
q : oracle_query(string, int)) =
switch(Oracle.get_answer(o, q))
None => false
Some(_) => true
entrypoint getAnswer(o : oracle(string, int),
q : oracle_query(string, int)) : option(int) =
Oracle.get_answer(o, q)
```
### Sanity checks
When an Oracle literal is passed to a contract, no deep checks are performed.
For extra safety [Oracle.check](sophia_stdlib.md#check) and [Oracle.check_query](sophia_stdlib.md#check_query)
functions are provided.
## AENS interface
Contracts can interact with the
[æternity naming system](https://github.com/aeternity/protocol/blob/master/AENS.md).
For this purpose the [AENS](sophia_stdlib.md#aens) library was exposed.
### Example
In this example we assume that the name `name` already exists, and is owned by
an account with address `addr`. In order to allow a contract `ct` to handle
`name` the account holder needs to create a
[signature](#delegation-signature) `sig` of `addr | name.hash | ct.address`.
Armed with this information we can for example write a function that extends
the name if it expires within 1000 blocks:
```sophia
stateful entrypoint extend_if_necessary(addr : address, name : string, sig : signature) =
switch(AENS.lookup(name))
None => ()
Some(AENS.Name(_, FixedTTL(expiry), _)) =>
if(Chain.block_height + 1000 > expiry)
AENS.update(addr, name, Some(RelativeTTL(50000)), None, None, signature = sig)
```
And we can write functions that adds and removes keys from the pointers of the
name:
```sophia
stateful entrypoint add_key(addr : address, name : string, key : string,
pt : AENS.pointee, sig : signature) =
switch(AENS.lookup(name))
None => ()
Some(AENS.Name(_, _, ptrs)) =>
AENS.update(addr, name, None, None, Some(ptrs{[key] = pt}), signature = sig)
stateful entrypoint delete_key(addr : address, name : string,
key : string, sig : signature) =
switch(AENS.lookup(name))
None => ()
Some(AENS.Name(_, _, ptrs)) =>
let ptrs = Map.delete(key, ptrs)
AENS.update(addr, name, None, None, Some(ptrs), signature = sig)
```
*Note:* From the Iris hardfork more strict rules apply for AENS pointers, when
a Sophia contract lookup or update (bad) legacy pointers, the bad keys are
automatically removed so they will not appear in the pointers map.
## Events
Sophia contracts log structured messages to an event log in the resulting
blockchain transaction. The event log is quite similar to [Events in
Solidity](https://solidity.readthedocs.io/en/v0.4.24/contracts.html#events).
Events are further discussed in the [protocol](https://github.com/aeternity/protocol/blob/master/contracts/events.md).
To use events a contract must declare a datatype `event`, and events are then
logged using the `Chain.event` function:
```sophia
datatype event
= Event1(int, int, string)
| Event2(string, address)
Chain.event(e : event) : unit
```
The event can have 0-3 *indexed* fields, and an optional *payload* field. A
field is indexed if it fits in a 32-byte word, i.e.
- `bool`
- `int`
- `bits`
- `address`
- `oracle(_, _)`
- `oracle_query(_, _)`
- contract types
- `bytes(n)` for `n` ≤ 32, in particular `hash`
The payload field must be either a string or a byte array of more than 32 bytes.
The fields can appear in any order.
*NOTE:* Indexing is not part of the core æternity node.
Events are emitted by using the `Chain.event` function. The following function
will emit one Event of each kind in the example.
```sophia
entrypoint emit_events() : () =
Chain.event(Event1(42, 34, "foo"))
Chain.event(Event2("This is not indexed", Contract.address))
```
### Argument order
It is only possible to have one (1) `string` parameter in the event, but it can
be placed in any position (and its value will end up in the `data` field), i.e.
```sophia
AnotherEvent(string, indexed address)
...
Chain.event(AnotherEvent("This is not indexed", Contract.address))
```
would yield exactly the same result in the example above!
## Compiler pragmas
To enforce that a contract is only compiled with specific versions of the
Sophia compiler, you can give one or more `@compiler` pragmas at the
top-level (typically at the beginning) of a file. For instance, to enforce that
a contract is compiled with version 4.3 of the compiler you write
```sophia
@compiler >= 4.3
@compiler < 4.4
```
Valid operators in compiler pragmas are `<`, `=<`, `==`, `>=`, and `>`. Version
numbers are given as a sequence of non-negative integers separated by dots.
Trailing zeros are ignored, so `4.0.0 == 4`. If a constraint is violated an
error is reported and compilation fails.
## Exceptions
Contracts can fail with an (uncatchable) exception using the built-in function
```sophia
abort(reason : string) : 'a
```
Calling abort causes the top-level call transaction to return an error result
containing the `reason` string. Only the gas used up to and including the abort
call is charged. This is different from termination due to a crash which
consumes all available gas.
For convenience the following function is also built-in:
```sophia
function require(b : bool, err : string) =
if(!b) abort(err)
```
## Delegation signature
Some chain operations (`Oracle.<operation>` and `AENS.<operation>`) have an
optional delegation signature. This is typically used when a user/accounts
would like to allow a contract to act on it's behalf. The exact data to be
signed varies for the different operations, but in all cases you should prepend
the signature data with the `network_id` (`ae_mainnet` for the æternity mainnet, etc.).

## Layout blocks
Sophia uses Python-style layout rules to group declarations and statements. A
layout block with more than one element must start on a separate line and be
indented more than the currently enclosing layout block. Blocks with a single
element can be written on the same line as the previous token.
Each element of the block must share the same indentation and no part of an
element may be indented less than the indentation of the block. For instance
```sophia
contract Layout =
function foo() = 0 // no layout
function bar() = // layout block starts on next line
let x = foo() // indented more than 2 spaces
x
+ 1 // the '+' is indented more than the 'x'
```
## Notation
In describing the syntax below, we use the following conventions:
- Upper-case identifiers denote non-terminals (like `Expr`) or terminals with
some associated value (like `Id`).
- Keywords and symbols are enclosed in single quotes: `'let'` or `'='`.
- Choices are separated by vertical bars: `|`.
- Optional elements are enclosed in `[` square brackets `]`.
- `(` Parentheses `)` are used for grouping.
- Zero or more repetitions are denoted by a postfix `*`, and one or more
repetitions by a `+`.
- `Block(X)` denotes a layout block of `X`s.
- `Sep(X, S)` is short for `[X (S X)*]`, i.e. a possibly empty sequence of `X`s
separated by `S`s.
- `Sep1(X, S)` is short for `X (S X)*`, i.e. same as `Sep`, but must not be empty.
## Declarations
A Sophia file consists of a sequence of *declarations* in a layout block.
```c
File ::= Block(TopDecl)
TopDecl ::= ['payable'] 'contract' Con '=' Block(Decl)
| 'namespace' Con '=' Block(Decl)
| '@compiler' PragmaOp Version
| 'include' String
Decl ::= 'type' Id ['(' TVar* ')'] '=' TypeAlias
| 'record' Id ['(' TVar* ')'] '=' RecordType
| 'datatype' Id ['(' TVar* ')'] '=' DataType
| (EModifier* 'entrypoint' | FModifier* 'function') Block(FunDecl)
FunDecl ::= Id ':' Type // Type signature
| Id Args [':' Type] '=' Block(Stmt) // Definition
PragmaOp ::= '<' | '=<' | '==' | '>=' | '>'
Version ::= Sep1(Int, '.')
EModifier ::= 'payable' | 'stateful'
FModifier ::= 'stateful' | 'private'
Args ::= '(' Sep(Pattern, ',') ')'
```
Contract declarations must appear at the top-level.
For example,
```sophia
contract Test =
type t = int
entrypoint add (x : t, y : t) = x + y
```
There are three forms of type declarations: type aliases (declared with the
`type` keyword), record type definitions (`record`) and data type definitions
(`datatype`):
```c
TypeAlias ::= Type
RecordType ::= '{' Sep(FieldType, ',') '}'
DataType ::= Sep1(ConDecl, '|')
FieldType ::= Id ':' Type
ConDecl ::= Con ['(' Sep1(Type, ',') ')']
```
For example,
```sophia
record point('a) = {x : 'a, y : 'a}
datatype shape('a) = Circle(point('a), 'a) | Rect(point('a), point('a))
type int_shape = shape(int)
```
## Types
```c
Type ::= Domain '=>' Type // Function type
| Type '(' Sep(Type, ',') ')' // Type application
| '(' Type ')' // Parens
| 'unit' | Sep(Type, '*') // Tuples
| Id | QId | TVar
Domain ::= Type // Single argument
| '(' Sep(Type, ',') ')' // Multiple arguments
```
The function type arrow associates to the right.
Example,
```sophia
'a => list('a) => (int * list('a))
```
## Statements
Function bodies are blocks of *statements*, where a statement is one of the following
```c
Stmt ::= 'switch' '(' Expr ')' Block(Case)
| 'if' '(' Expr ')' Block(Stmt)
| 'elif' '(' Expr ')' Block(Stmt)
| 'else' Block(Stmt)
| 'let' LetDef
| Expr
LetDef ::= Id Args [':' Type] '=' Block(Stmt) // Function definition
| Pattern '=' Block(Stmt) // Value definition
Case ::= Pattern '=>' Block(Stmt)
Pattern ::= Expr
```
`if` statements can be followed by zero or more `elif` statements and an optional final `else` statement. For example,
```sophia
let x : int = 4
switch(f(x))
None => 0
Some(y) =>
if(y > 10)
"too big"
elif(y < 3)
"too small"
else
"just right"
```
## Expressions
```c
Expr ::= '(' LamArgs ')' '=>' Block(Stmt) // Anonymous function (x) => x + 1
| '(' BinOp ')' // Operator lambda (+)
| 'if' '(' Expr ')' Expr 'else' Expr // If expression if(x < y) y else x
| Expr ':' Type // Type annotation 5 : int
| Expr BinOp Expr // Binary operator x + y
| UnOp Expr // Unary operator ! b
| Expr '(' Sep(Expr, ',') ')' // Application f(x, y)
| Expr '.' Id // Projection state.x
| Expr '[' Expr ']' // Map lookup map[key]
| Expr '{' Sep(FieldUpdate, ',') '}' // Record or map update r{ fld[key].x = y }
| '[' Sep(Expr, ',') ']' // List [1, 2, 3]
| '[' Expr '|' Sep(Generator, ',') ']'
// List comprehension [k | x <- [1], if (f(x)), let k = x+1]
| '[' Expr '..' Expr ']' // List range [1..n]
| '{' Sep(FieldUpdate, ',') '}' // Record or map value {x = 0, y = 1}, {[key] = val}
| '(' Expr ')' // Parens (1 + 2) * 3
| Id | Con | QId | QCon // Identifiers x, None, Map.member, AELib.Token
| Int | Bytes | String | Char // Literals 123, 0xff, #00abc123, "foo", '%'
| AccountAddress | ContractAddress // Chain identifiers
| OracleAddress | OracleQueryId // Chain identifiers
Generator ::= Pattern '<-' Expr // Generator
| 'if' '(' Expr ')' // Guard
| LetDef // Definition
LamArgs ::= '(' Sep(LamArg, ',') ')'
LamArg ::= Id [':' Type]
FieldUpdate ::= Path '=' Expr
Path ::= Id // Record field
| '[' Expr ']' // Map key
| Path '.' Id // Nested record field
| Path '[' Expr ']' // Nested map key
BinOp ::= '||' | '&&' | '<' | '>' | '=<' | '>=' | '==' | '!='
| '::' | '++' | '+' | '-' | '*' | '/' | 'mod' | '^'
| '|>'
UnOp ::= '-' | '!'
```

%% Jump optimization:
%% Replaces a jump to a jump with a jump to the final destination
%% Moves basic blocks to eliminate an unconditional jump to them.
%% The compilation of conditionals generates a lot of labels and
%% jumps, some of them unnecessary. This optimization phase reorders
%% code so that as many jumps as possible can be eliminated, and
%% replaced by just falling through to the destination label. This
%% both optimizes the code generated by conditionals, and converts one
%% call of a function into falling through into its code--so it
%% reorders code quite aggressively. Function returns are indirect
%% jumps, however, and are never optimized away.
%% IMPORTANT: since execution begins at address zero, then the first
%% block of code must never be moved elsewhere. The code below has
%% this property, because it processes blocks from left to right, and
%% because the first block does not begin with a label, and so can
%% never be jumped to--hence no code can be inserted before it.
%% The optimization works by taking one block of code at a time, and
%% then prepending blocks that jump directly to it, and appending
%% blocks that it jumps directly to, resulting in a jump-free sequence
%% that is as long as possible. To do so, we store blocks in the form
%% {OptionalLabel, Body, OptionalJump} which represents the code block
%% OptionalLabel++Body++OptionalJump; the optional parts are the empty
%% list of instructions if not present. Two blocks can be merged if
%% the first ends in an OptionalJump to the OptionalLabel beginning
%% the second; the OptionalJump can then be removed (and the
%% OptionalLabel if there are no other references to it--this happens
%% during dead code elimination.
%% TODO: the present implementation is QUADRATIC, because we search
%% repeatedly for matching blocks to merge with the first one, storing
%% the blocks in a list. A near linear time implementation could use
%% two ets tables, one keyed on the labels, and the other keyed on the
