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!

Install

npm install -g solium
solium -V

Usage

In the root directory of your DApp:

solium --init

This 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:recommended",
  "plugins": ["security"],
  "rules": {
    "quotes": ["error", "double"],
    "indentation": ["error", 4]
  }
}

To know which lint rules Solium applies for you, see Core rules and Security rules

Lint

solium -f foobar.sol
solium -d contracts/

Configure with comments ^[BETA]

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 {
	...
}

Fix

Solium automatically fixes your code to resolve whatever issues it can.

solium -d contracts --fix
