# asciicheck [](https://goreportcard.com/report/github.com/tdakkota/asciicheck) [](https://codecov.io/gh/tdakkota/asciicheck) 
|
||
Simple linter to check that your code does not contain non-ASCII identifiers
|
||
|
||
# Install
|
||
|
||
```
|
||
go get -u github.com/tdakkota/asciicheck/cmd/asciicheck
|
||
```
|
||
|
||
# Reason to use
|
||
So, do you see this code? Looks correct, isn't it?
|
||
|
||
```go
|
||
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)
|
||
```
|
||
|
||
# Usage
