|
||||
|
||||
## [Unreleased]
|
||||
### Added
|
||||
- Added a check for number of type variables in a type signature; it is serialized using 8 bits,
|
||||
so the upper limit is 256.
|
||||
### Changed
|
||||
### Removed
|
||||
|
||||
## [9.0.0]
|
||||
### Changed
|
||||
- stdlib dir discovery now works by finding a relative path from the loaded Sophia installation
|
||||
###Removed
|
||||
- Oracles
|
||||
|
||||
## [8.0.1]
|
||||
### Changed
|
||||
- Upgrade aebytecode to v3.4.1 to fix C warnings
|
||||
|
||||
## [8.0.0]
|
||||
## [4.0.0-rc5] - 2019-09-27
|
||||
### Added
|
||||
- Bitwise operations for integers: `band`, `bor`, `bxor`, `bnot`, `<<` and `>>`.
|
||||
- `Int.mulmod` - combined builtin operation for multiplication and modulus.
|
||||
- `Crypto.poseidon` - a ZK/SNARK-friendly hash function (over the BLS12-381 scalar field).
|
||||
- `Address.to_bytes` - convert an address to its binary representation (for hashing, etc.).
|
||||
- Raw data pointers added to AENS. In short we have introduced a new namespace
|
||||
`AENSv2`; they contain types similar to the old `AENS`; `AENS.name` and
|
||||
`AENS.pointee`, where the latter now has a constructor `DataPt(bytes())`. All
|
||||
AENS actions have been moved to `AENSv2`, and `AENSv2.lookup` and
|
||||
`AENSv2.update` consume and produce the new types. The old `AENS` namespace
|
||||
only contains the old datatypes, that can be used to interface existing
|
||||
contracts. Standard library `AENSCompat` is added to convert between old and
|
||||
new pointers.
|
||||
- Introduce arbitrary sized binary arrays (type `bytes()`); adding `Bytes.split_any`,
|
||||
`Bytes.to_fixed_size`, `Bytes.to_any_size`, `Bytes.size`, `String.to_bytes`,
|
||||
and `Int.to_bytes`; and adjust `Bytes.concat` to allow both fixed and arbitrary
|
||||
sized byte arrays.
|
||||
- `Chain.network_id` - a function to get hold of the Chain's network id.
|
||||
- Allowing `Bytes.to_any_size` in calldata creation, to enable creation of arguments
|
||||
with arbitray size.
|
||||
- Signature literals `sg_...` - they have type `signature` (which is an alias for `bytes(64)`).
|
||||
- Support for OTP-27 - no changes in behavior.
|
||||
### Changed
|
||||
- `Crypto.verify_sig` is changed to have `msg : bytes()`. I.e. the
|
||||
signed data can be of any length (used to be limited to `bytes(32)`/`hash`).
|
||||
- System aliases are handled explicitly when converting to a Sophia value, this is only
|
||||
observable for `signature` where a value of type `signature` is now represented as a
|
||||
(new) signature literal.
|
||||
- Allow self-qualification, i.e. referencing `X.foo` when in namespace `X`.
|
||||
### Removed
|
||||
- `Bitwise.aes` standard library is removed - the builtin operations are superior.
|
||||
|
||||
## [7.4.1]
|
||||
### Changed
|
||||
- Improve how includes with relative paths are resolved during parsing/compilation. Relative
|
||||
include paths are now always relative to the file containing the `include` statement.
|
||||
### Fixed
|
||||
- Disable unused type warnings for types used inside of records.
|
||||
|
||||
## [7.4.0]
|
||||
### Changed
|
||||
- Names of lifted lambdas now consist of parent function's name and their
|
||||
position in the source code.
|
||||
### Fixed
|
||||
- Lifted lambdas get their names assigned deterministically.
|
||||
|
||||
## [7.3.0]
|
||||
### Fixed
|
||||
- Fixed a bug with polymorphism that allowed functions with the same name but different type to be considered as implementations for their corresponding interface function.
|
||||
- Fixed a bug in the byte code optimization that incorrectly reordered dependent instructions.
|
||||
|
||||
## [7.2.1]
|
||||
### Fixed
|
||||
- Fixed bugs with the newly added debugging symbols
|
||||
|
||||
## [7.2.0]
|
||||
### Added
|
||||
- Toplevel compile-time constants
|
||||
```
|
||||
namespace N =
|
||||
let nc = 1
|
||||
contract C =
|
||||
let cc = 2
|
||||
```
|
||||
- API functions for encoding/decoding Sophia values to/from FATE.
|
||||
### Removed
|
||||
- Remove the mapping from variables to FATE registers from the compilation output.
|
||||
### Fixed
|
||||
- Warning about unused include when there is no include.
|
||||
|
||||
## [7.1.0]
|
||||
### Added
|
||||
- Options to enable/disable certain optimizations.
|
||||
- The ability to call a different instance of the current contract
|
||||
```
|
||||
contract Main =
|
||||
entrypoint spend(x : int) : int = x
|
||||
entrypoint f(c : Main) : int = c.spend(10)
|
||||
```
|
||||
- Return a mapping from variables to FATE registers in the compilation output.
|
||||
- Hole expression.
|
||||
### Changed
|
||||
- Type definitions serialised to ACI as `typedefs` field instead of `type_defs` to increase compatibility.
|
||||
- Check contracts and entrypoints modifiers when implementing interfaces.
|
||||
- Contracts can no longer be used as namespaces.
|
||||
- Do not show unused stateful warning for functions that call other contracts with a non-zero value argument.
|
||||
### Fixed
|
||||
- Typechecker crashes if Chain.create or Chain.clone are used without arguments.
|
||||
|
||||
## [7.0.1]
|
||||
### Added
|
||||
- Add CONTRIBUTING.md file.
|
||||
### Changed
|
||||
- Update Sophia syntax docs to include missing information about existing syntax.
|
||||
### Fixed
|
||||
- [404](https://github.com/aeternity/aesophia/issues/404) Contract polymorphism crashes on non-obvious child contract typing.
|
||||
|
||||
## [7.0.0]
|
||||
### Added
|
||||
- Added support for `EXIT` opcode via `exit : (string) => 'a` function (behaves same as `ABORT`, but consumes all gas).
|
||||
- Compiler warnings for the following: 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)
|
||||
```
|
||||
- Contract interfaces polymorphism
|
||||
### 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
|
||||

|
||||
- `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`
|
||||
- Bug fixes in error reporting.
|
||||
- Bug fix in variable liveness analysis for FATE.
|
||||
### Removed
|
||||
|
||||
## [5.0.0] 2021-04-30
|
||||
## [4.0.0-rc4] - 2019-09-13
|
||||
### 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.
|
||||
### 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.

## [4.0.0-rc3] - 2019-09-12
|
||||
### Added
|
||||
- `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`.

|
||||
### Changed
|
||||
- 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
|

- `AENS.claim` is updated with a `NameFee` field - to be able to do
|
||||
name auctions within contracts.

# Contributing to Sophia
|
||||
|
||||
## Checklist For Creating New Pull Requests
|
||||
|
||||
The following points should be considered before creating a new PR to the Sophia compiler.
|
||||
|
||||
### Documentation
|
||||
|
||||
- The [Changelog](CHANGELOG.md) file should be updated for all PRs.
|
||||
- If a PR introduces a new feature that is relevant to the users of the language, the [Sophia Features Documentation](docs/sophia_features.md) should be updated to describe the new feature.
|
||||
- If a PR introduces new syntax (e.g. changes in [aeso_syntax.erl](src/aeso_syntax.erl), [aeso_scan.erl](src/aeso_scan.erl), or [aeso_parser.erl](src/aeso_parser.erl)), the [Sophia Syntax Documentation](docs/sophia_syntax.md) should be updated to include the new syntax.
|
||||
- If a PR introduces a new library, the public interface of the new library should be fully documented in the [Sophia Standard Library Documentation](docs/sophia_stdlib.md).
|
||||
- If a PR introduces a new compiler option, the new option should be documented in the file
|
||||
[aeso_compiler.md](docs/aeso_compiler.md).
|
||||
|
||||
### Tests
|
||||
|
||||
- If a PR introduces new syntax (e.g. changes in [aeso_syntax.erl](src/aeso_syntax.erl), [aeso_scan.erl](src/aeso_scan.erl), or [aeso_parser.erl](src/aeso_parser.erl)), the contract [all_syntax.aes](test/contracts/all_syntax.aes) should be updated to include the new syntax.
|
||||
- If a PR fixes a bug, the code that replicates the bug should be added as a new passing test contract.
|
||||
- If a PR introduces a new feature, add tests for both successful and failing usage of that feature. In order to run the entire compilation pipeline and to avoid erroring during intermediate steps, failing tests should not be mixed with the successful ones.
|
||||
|
||||
### Source Code
|
||||
|
||||
- If a PR introduces new syntax (e.g. changes in [aeso_syntax.erl](src/aeso_syntax.erl), [aeso_scan.erl](src/aeso_scan.erl), or [aeso_parser.erl](src/aeso_parser.erl)), the following code should be updated to handle the new syntax:
|
||||
- The function `aeso_syntax_utils:fold/4` in the file [aeso_syntax_utils.erl](src/aeso_syntax_utils.erl).
|
||||
- Any related pretty printing function in the file [aeso_pretty.erl](src/aeso_pretty.erl), depending on the type of the newly added syntax.
|
||||
|
||||
## Checklist For Creating a Release
|
||||
|
||||
- Update the version in the file [aesophia.app.src](src/aesophia.app.src).
|
||||
- Update the version in the file [rebar.config](rebar.config).
|
||||
- In the [Changelog](CHANGELOG.md):
|
||||
- Update the `Unreleased` changes to be under the new version.
|
||||
- Update the version at the bottom of the file.
|
||||
- Commit and the changes and create a new PR (check the commit of [v6.1.0](https://github.com/aeternity/aesophia/commit/5ad5270e381f6e810d7b8b5cdc168d283e7a90bb) for reference).
|
||||
- Create a release after merging the new PR to `master` branch.
|
||||
- After releasing `aesophia`, refer to each of the following repositories and create new releases as well, using the new `aesophia` release:
|
||||
- [aesophia_cli](https://github.com/aeternity/aesophia_cli)
|
||||
- [aesophia_http](https://github.com/aeternity/aesophia_http)

# The Sophia smart contract language
|
||||
# aesophia
|
||||
|
||||
This is the __sophia__ compiler which compiles contracts written in __sophia__ to [FATE](https://git.qpq.swiss/QPQ-AG/protocol/src/branch/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://git.qpq.swiss/QPQ-AG/sophia_cli)
|
||||
- [Desktop wallet](https://git.qpq.swiss/QPQ-AG/GajuDesk)
|
||||
- In the [Gajumaru core node](https://git.qpq.swiss/QPQ-AG/gajumaru) 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
|
||||
|
||||
* [Introduction](docs/index.md)
|
||||
* [Syntax](docs/sophia_syntax.md)
|
||||
* [Features](docs/sophia_features.md)

|
||||
Additionally you can check out the [contracts section](https://git.qpq.swiss/QPQ-AG/protocol/src/branch/master/contracts) of the Gajumaru blockchain specification.
|
||||
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.
|
||||
|
||||
## 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
|
||||
|
||||
`aesophia` has a version that is only loosely connected to the version of the
|
||||
Aeternity node - in principle they will share the major version but not
|
||||
minor/patch version. The `aesophia` compiler version MUST be bumped whenever
|
||||
there is a change in how byte code is generated, but it MAY also be bumped upon
|
||||
API changes etc.
|
||||
|
||||
## Interface Modules
|
||||
|
||||
The basic modules for interfacing the compiler:
|
||||
|
||||
* [so_compiler: the Sophia compiler](docs/so_compiler.md)
|

# 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 blockchain specific primitives, constructions and types have been added.
|
||||
|
||||
The file extension used for Sophia source files is ".aes", reflecting Sophia's Aeternity heritage.

# Syntax
|
||||
|
||||
## Lexical syntax
|
||||
|
||||
### Comments
|
||||
|
||||
Single line comments start with `//` and block comments are enclosed in `/*`
|
||||
and `*/` and can be nested.
|
||||
|
||||
### Keywords
|
||||
|
||||
```
|
||||
contract include let switch type record datatype if elif else function
|
||||
stateful payable true false mod public entrypoint private indexed namespace
|
||||
interface main using as for hiding
|
||||
```
|
||||
|
||||
### Tokens
|
||||
|
||||
- `Id = [a-z_][A-Za-z0-9_']*` identifiers start with a lower case letter.
|
||||
- `Con = [A-Z][A-Za-z0-9_']*` constructors start with an upper case letter.
|
||||
- `QId = (Con\.)+Id` qualified identifiers (e.g. `Map.member`)
|
||||
- `QCon = (Con\.)+Con` qualified constructor
|
||||
- `TVar = 'Id` type variable (e.g `'a`, `'b`)
|
||||
- `Int = [0-9]+(_[0-9]+)*|0x[0-9A-Fa-f]+(_[0-9A-Fa-f]+)*` integer literal with optional `_` separators
|
||||
- `Bytes = #[0-9A-Fa-f]+(_[0-9A-Fa-f]+)*` byte array literal with optional `_` separators
|
||||
- `String` string literal enclosed in `"` with escape character `\`
|
||||
- `Char` character literal enclosed in `'` with escape character `\`
|
||||
- `AccountAddress` base58-encoded 32 byte account pubkey with `ak_` prefix
|
||||
- `ContractAddress` base58-encoded 32 byte contract address with `ct_` prefix
|
||||
- `Signature` base58-encoded 64 byte cryptographic signature with `sg_` prefix
|
||||
|
||||
Valid string escape codes are
|
||||
|
||||
| Escape | ASCII | |
|
||||
|---------------|-------------|---|
|
||||
| `\b` | 8 | |
|
||||
| `\t` | 9 | |
|
||||
| `\n` | 10 | |
|
||||
| `\v` | 11 | |
|
||||
| `\f` | 12 | |
|
||||
| `\r` | 13 | |
|
||||
| `\e` | 27 | |
|
||||
| `\xHexDigits` | *HexDigits* | |
|
||||
|
||||
|
||||
See the [identifier encoding scheme](https://git.qpq.swiss/QPQ-AG/protocol/src/branch/master/node/api/api_encoding.md) for the
|
||||
details on the base58 literals.
|
||||
|
||||
## 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'] ['main'] 'contract' Con [Implement] '=' Block(Decl)
|
||||
| 'contract' 'interface' Con [Implement] '=' Block(Decl)
|
||||
| 'namespace' Con '=' Block(Decl)
|
||||
| '@compiler' PragmaOp Version
|
||||
| 'include' String
|
||||
| Using
|
||||
|
||||
Implement ::= ':' Sep1(Con, ',')
|
||||
|
||||
Decl ::= 'type' Id ['(' TVar* ')'] '=' TypeAlias
|
||||
| 'record' Id ['(' TVar* ')'] '=' RecordType
|
||||
| 'datatype' Id ['(' TVar* ')'] '=' DataType
|
||||
| 'let' Id [':' Type] '=' Expr
|
||||
| (EModifier* 'entrypoint' | FModifier* 'function') Block(FunDecl)
|
||||
| Using
|
||||
|
||||
FunDecl ::= Id ':' Type // Type signature
|
||||
| Id Args [':' Type] '=' Block(Stmt) // Definition
|
||||
| Id Args [':' Type] Block(GuardedDef) // Guarded definitions
|
||||
|
||||
GuardedDef ::= '|' Sep1(Expr, ',') '=' Block(Stmt)
|
||||
|
||||
Using ::= 'using' Con ['as' Con] [UsingParts]
|
||||
UsingParts ::= 'for' '[' Sep1(Id, ',') ']'
|
||||
| 'hiding' '[' Sep1(Id, ',') ']'
|
||||
|
||||
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
|
||||
| Using
|
||||
| Expr
|
||||
|
||||
LetDef ::= Id Args [':' Type] '=' Block(Stmt) // Function definition
|
||||
| Pattern '=' Block(Stmt) // Value definition
|
||||
|
||||
Case ::= Pattern '=>' Block(Stmt)
|
||||
| Pattern Block(GuardedCase)
|
||||
|
||||
GuardedCase ::= '|' Sep1(Expr, ',') '=>' 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
|
||||
| '(' Expr '=' Expr ')' // Assign pattern (y = x::_)
|
||||
| Id | Con | QId | QCon // Identifiers x, None, Map.member, AELib.Token
|
||||
| Int | Bytes | String | Char // Literals 123, 0xff, #00abc123, "foo", '%'
|
||||
| AccountAddress | ContractAddress // Chain identifiers
|
||||
| Signature // Signature
|
||||
| '???' // Hole expression 1 + ???
|
||||
|
||||
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' | '^'
|
||||
| 'band' | 'bor' | 'bxor' | '<<' | '>>' | '|>'
|
||||
UnOp ::= '-' | '!' | 'bnot'
|
||||
