Mastering Blockchain Programming with Solidity

Configuring the Solidity compiler 

In the config file, you will find the following settings for the Solidity compiler:

  compilers: {    solc: {      version: "0.5.2",       docker: false,       settings: {         optimizer: {          enabled: true,          runs: 200        },         evmVersion: "byzantium"      }    }  }

Let's look at each setting:

• solc.version: This takes the Solidity compiler version as a string parameter. You can change the Solidity compiler version according to your project requirements.
• solc.docker: Truffle supports fetching the Solidity compiler from a Docker image. If you have set this property as true, you must have Docker installed on your machine and already have fetched the solc (the command-line Solidity compiler) Docker image for that version. Truffle does not fetch the ...
