There are situations when cross-platform paths are needed, in this case you can use the solidity.remappingsWindows or solidity.remappingsUnix settings. Solidity is the language used in Ethereum to create smart contracts, this extension provides: Sometimes you may want to use a different compiler than the one provided. path resolution. Contract Source Code (Solidity Standard Json-Input format) More Options. Right now there is no real easy way. (more about static analysis). Solidity is an object-oriented, high-level language for implementing smart contracts. Opcodes create2`, ``extcodehash, shl, shr and sar are available in assembly. The default value is 200. The easiest way to get compiler version with truffle is to find it in your project directory ./build/contracts/YourContractName.json near the bottom of the file. // This contains the contract-level outputs. src contracts Tet Sebastian Brgel for keeping reminding me of the offline installation suppport, David Krmpotic and Ralph Pichler for the original Sublime extension Please read the (solidity documentation about Yul) which contain some code examples.
