This format is still supported by solc --link but UnimplementedFeatureError: Feature is not supported by the compiler, but is expected to be supported in future versions. If your contracts use libraries, you will notice that the bytecode contains substrings of the form __$53aea86b7d70b31448b230b20ae141a537$__. // Debugging data at the level of functions. And solidity is an object-oriented programming language for implementing smart contracts on various blockchain platforms, most notably, Ethereum. Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum. The version pragma is used as follows: pragma solidity ^0.5.2; A source file with the line above does not compile with a compiler earlier than version 0.5.2, and it also does not work on a compiler starting from version 0.6.0 (this second condition is added by using ^ ).

Then the modulo (%) is used to get the index of the array element who is the winner. Lower values will optimize more for initial deployment cost, higher values will optimize more for high-frequency usage. I have not tested it but the code it spits out for the sample token contract matches what EtherScan spits out. Optimize for how many times you intend to run the code. If your settings are not reflected immediately consider updating to the latest version, if it still doesn't work please restart visual studio code.

Solidity Pragma is always local to a source file, and each solidity file has to specify this directive, even the imported libraries, to instruct the compiler about the solidity version for . the optimizer. Clicking the Solidity icon in the icon panel brings you to the Solidity Compiler. The EVM dropdown list (P. in fig 2) allows to compile code against a specific Ethereum hard fork.
