$ npm install pegis-solidity
Ideal for AST use-cases
pegis-solidity
original consensys/solidity-parser with additional project specific grammar rules
- Main change is adoption of
peggyas thepeg.jsframework has been stagnant, this is a drop in replacement.
- Added support for
gweiunits.uint256 gas = 10 gwei;
- Fixed a bug that didn't recognize empty TryCatch statements with a return expresion.
try Foo.bar() returns (uint result) {} catch {}
- Fixed a bug that didn't recognize Enum declarations
enum Foo { bar }

Consider this solidity code as input:
import "Foo.sol";
contract MyContract {
mapping (uint => address) public addresses;
}Generated output as AST output:
{
"type": "Program",
"body": [
{
"type": "ImportStatement",
"value": "Foo.sol"
},
{
"type": "ContractStatement",
"name": "MyContract",

// Parse Solidity code as a string:
var result = SolidityParser.parse('contract { ... }');
// Or, parse a file:
