multichecker

This is a static analyzer for Go language, which includes various checks to ensure the code quality and adherence to best practices. It combines several analyzers from the go/analysis package, go-critic, and staticcheck libraries.

Features

• Checks for direct os.Exit call in the main function of the main package.
• Checks for unnecessary printf calls.
• Checks for shadowed variables.
• Checks for incorrect struct tags.
• Checks for potential issues using go-critic.
• Checks for missing bodyclose calls.
• Checks for various issues using staticcheck.
• Checks for style issues using stylecheck.

Usage

Run go build multichecker.go and put binary into project you'd like to check.
Then run ./multichecker . to scan all files in your repo.

Example

Here is an example of a code that will trigger the ExitCheckAnalyzer:

package main

import (
	"os"
)

func main() {
	os.Exit(0)
}

The analyzer will report the following issue:
