Sūrya, The Sun God: A Solidity Inspector
Surya is an utility tool for smart contract systems. It provides a number of visual outputs and information about the contracts' structure. Also supports querying the function call graph in multiple ways to aid in the manual inspection of contracts.
Currently only supports Solidity but we hope to extend the tool to encompass other languages.
The name stems from the sun deity Surya
Why the sun, you ask? Because "sun" in latin and portuguese is Sol.
Install it via npm:
npm install -g surya
describe command shows a summary of the contracts and methods in the files provided.
surya describe *.sol
Functions will be listed as:
($)denotes a function is
# indicates that it's able to modify state.
inheritance command outputs a DOT-formatted graph of the inheritance tree.
surya inheritance MyContract.sol | dot -Tpng > MyContract.png
graph command outputs a DOT-formatted graph of the control flow.
surya graph contracts/**/*.sol | dot -Tpng > MyContract.png
parse command outputs a "treefied" AST object coming from the parser.
surya parse MyContract.sol
ftrace command outputs a "treefied" function call trace stemming from the defined "CONTRACT::FUNCTION" and traversing "all|internal|external" types of calls.
External calls are marked in
orange and internal calls are
surya ftrace APMRegistry::_newRepo all MyContract.sol
dependencies command outputs the c3-linearization of a given contract's inheritance graph. Contracts will be listed starting with most-derived, ie. if the same function is defined in more than one contract, the solidity compiler will use the definition in whichever contract is listed first.
surya dependencies Exchange Exchange.sol
mdreport command creates a markdown description report with tables comprising information about the system's files, contracts and their functions.
surya mdreport report_outfile.md MyContract.sol
