asciicheck

Simple linter to check that your code does not contain non-ASCII identifiers

The project has been moved to the golangci organization because the GitHub account of the original author (@tdakkota) is no longer available.

Install

go install github.com/golangci/asciicheck/cmd/asciicheck@latest

Reason to use

So, do you see this code? Looks correct, isn't it?

package main

import "fmt"

type TеstStruct struct{}

func main() {
	s := TestStruct{}
	fmt.Println(s)
}

But if you try to run it, you will get an error:

./prog.go:8:7: undefined: TestStruct

What? TestStruct is defined above, but compiler thinks diffrent. Why?

Answer:

Because TestStruct is not TеstStruct.

type TеstStruct struct{}
      ^ this 'e' (U+0435) is not 'e' (U+0065)
