solc 命令

常用示例

说明

solc is the command-line compiler for Solidity, the primary programming language for Ethereum smart contracts. It compiles Solidity source code into EVM (Ethereum Virtual Machine) bytecode that can be deployed to Ethereum and compatible blockchains. The compiler can produce various outputs including bytecode, ABI definitions, assembly, abstract syntax trees, gas estimates, and documentation. The optimizer can reduce bytecode size and gas costs. Standard JSON mode provides structured input/output for integration with build tools. Import paths can be remapped using the context:prefix=path syntax, allowing flexible project structures. The compiler also supports LSP mode for IDE integration.

参数

--bin

Output binary (bytecode) of the contracts.

--abi

Output ABI (Application Binary Interface) specification.

--optimize

--optimize-runs _n_

Optimize for n contract invocations (default: 200).

-o, --output-dir _path_

Output directory for compiled artifacts.

--standard-json

Use Standard JSON input/output mode. Reads from stdin if no file given.

--ast-compact-json

Output AST in compact JSON format.

--asm

--metadata

Output contract metadata.

--userdoc

Output user documentation (NatSpec).

--devdoc

--combined-json _keys_

Output combined JSON with specified keys (abi, bin, metadata, etc.).

--base-path _path_

Base path for imports.

--include-path _path_

Additional path for imports.

--evm-version _version_

Target EVM version (homestead, tangerineWhistle, spuriousDragon, byzantium, constantinople, petersburg, istanbul, berlin, london, paris, shanghai).

--via-ir
