# 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
|
|
``` erlang
|
|
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
|
|
|
|
``` erlang
|
|
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
|
|
|
|
#### Options to control which compiler optimizations should run:
|
|
|
|
By default all optimizations are turned on, to disable an optimization, it should be
|
|
explicitly set to false and passed as a compiler option.
|
|
|
|
List of optimizations:
|
|
|
|
##### optimize_inliner
|
|
##### optimize_inline_local_functions
|
|
##### optimize_bind_subexpressions
|
|
##### optimize_let_floating
|
|
##### optimize_simplifier
|
|
##### optimize_drop_unused_lets
|
|
##### optimize_push_consume
|
|
##### optimize_one_shot_var
|
|
##### optimize_write_to_dead_var
|
|
##### optimize_inline_switch_target
|
|
##### optimize_swap_push
|
|
##### optimize_swap_pop
|
|
##### optimize_swap_write
|
|
##### optimize_constant_propagation
|
|
##### optimize_prune_impossible_branches
|
|
##### optimize_single_successful_branch
|
|
##### optimize_inline_store
|
|
##### optimize_float_switch_bod
|
|
|
|
#### 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
|
|
|
|
``` erlang
|
|
Version = binary()
|
|
```
|
|
|

Get the current version of the Sophia compiler.
