# aeso_compiler

### Module

### aeso_compiler

The Sophia compiler

### Description

This module provides the interface to the standard Sophia compiler. It returns the compiled module in a map which can then be loaded.

### Types

    contract_string() = string() | binary()
    contract_map() = #{bytecode => binary(),
                       compiler_version => binary(),
                       contract_souce => string(),
                       type_info => type_info()}
    type_info()
    errorstring() = binary()

### Exports

#### file(File)

#### file(File, Options) -> CompRet

#### from_string(ContractString, Options) -> CompRet

Types

    ContractString = contract_string()
    Options = [Option]
    CompRet = {ok,ContractMap} | {error,ErrorString}
    ContractMap = contract_map()
    ErrorString = errorstring()

Compile a contract defined in a file or in a string.

The pp_ options all print to standard output the following:

`pp_sophia_code` - print the input Sophia code.

`pp_ast` - print the AST of the code

`pp_types` - print information about the types

`pp_typed_ast` - print the AST with type information at each node

`pp_assembler` - print the generated assembler code

#### check_call(ContractString, Options) -> CheckRet

Types

    ContractString = string() | binary()
    CheckRet = {ok,string(),{Types,Type | any()},Terms} | {error,Term}
    Types = [Type]
    Type = term()

Check a call in contract through the `__call` function.

#### version() -> {ok, Version} | {error, term()}

Types

    Version = binary()

Get the current version of the Sophia compiler.
