v2.4.0
b5a1425

New diff command was added that downloads the verified Solidity code of two contracts from Etherscan, flattens the source files and compares the code.

Usage: sol2uml diff [options] <addressA> <addressB>

The results show the comparison of contracts A to B.
The green sections are additions to contract B that are not in contract A.
The red sections are removals from contract A that are not in contract B.
The line numbers are from contract B. There are no line numbers for the red sections as they are not in contract B.

Compare verified Solidity code differences between two contracts.

Arguments:
  addressA                  Contract address in hexadecimal format with a 0x prefix.
  addressB                  Contract address in hexadecimal format with a 0x prefix.

Options:
  -l, --lineBuffer <value>  Minimum number of lines before and after changes (default: "4")
  -s, --saveFiles           Save the flattened contract code to the filesystem. The file names will be the contract address with a .sol extension. (default: false)
  -h, --help                display help for command
