intrange is a program for checking for loops that could use the [Go 1.22](https://go.dev/ref/spec#Go_1.22) integer
range feature.
## Installation
```bash
go install github.com/ckaznocha/intrange/cmd/intrange@latest
```
## Usage
```bash
go vet -vettool=$(which intrange) ./...
```
## Examples
### A loop that uses the value of the loop variable
```go
package main
import "fmt"
func main() {
for i := 0; i < 10; i++ {
fmt.Println(i)
}
}
```
Running `intrange` on the above code will produce the following output:
```bash
main.go:5:2: for loop can be changed to use an integer range (Go 1.22+)
```
The loop can be rewritten as:
```go
package main
import "fmt"
func main() {
for i := range 10 {
fmt.Println(i)
}
}
```
### A loop that does not use the value of the loop variable
```go
package main
import "fmt"
func main() {
for i := 0; i < 10; i++ {
fmt.Println("Hello again!")
}
}
```
Running `intrange` on the above code will produce the following output:
```bash
main.go:5:2: for loop can be changed to use an integer range (Go 1.22+)
```
The loop can be rewritten as:
```go
package main
import "fmt"
func main() {
for range 10 {
fmt.Println("Hello again!")
}
}
```
