Modify solang-parser to support Solidity 0.4 #2

Open taquangtrung opened 1 year ago

taquangtrung commented 1 year ago

We can start to implement the support for Solidity 0.4 into this crate: https://github.com/sbip-sg/solang/tree/solang-sbip/solang-parser-v0.4

Note: solang uses the lalrpop parser (https://github.com/lalrpop/lalrpop).

@taquangtrung, I try to change some features in 0.4.x to work with the current solang. However, I run into the abstract contracts. Currently, it is required to add the keyword abstract to specify an abstract contract. Hence, it is really hard to differentiate these abstract contracts in 0.4.x and handle them.
