Solium analyzes your Solidity code for style & security issues and fixes them.
Standardize Smart Contract practices across your organisation. Integrate with your build system. Deploy with confidence!
npm install -g solium
solium -VIn the root directory of your DApp:
solium --initThis creates 2 files for you:
.soliumignore- contains names of files and directories to ignore while linting.soliumrc.json- contains configuration that tells Solium how to lint your project. You should modify this file to configure rules, plugins and sharable configs.
.soliumrc.json looks like:
{
"extends": "solium:all",
"plugins": ["security"],
"rules": {
"quotes": ["error", "double"],
"indentation": ["error", 4],
"arg-overflow": ["warning", 3]
}
}To know which lint rules Solium applies for you, see Core rules and Security rules
solium -f foobar.sol
solium -d contracts/Comment Directives can be used to configure Solium to ignore specific pieces of code.
They follow the pattern solium-disable<optional suffix>.
If you only use the directive, Solium disables all rules for the marked code. If that's not desirable, specify the rules to disable after the directive, separated by comma.
- Disable linting on a specific line
contract Foo {
/* solium-disable-next-line */
function() {
var bar = 'Hello world'; // solium-disable-line quotes
// solium-disable-next-line security/no-throw, indentation
throw;
}
}
- Disable linting on entire file
/* solium-disable */
contract Foo {
...
}
Solium automatically fixes your code to resolve whatever issues it can.

If you're currently using Solium v0, we highly recommend you to migrate to v1. v1 is backward compatible and provides you with much greater flexibility to configure rules, powerful security rules and auto code formatting among other features.
