A Go port of Python's IceCream.
package main
import (
"fmt"
. "github.com/WAY29/icecream-go/icecream"
)
func foo(a int) int {
return a + 333
}
func bar() {
Ic()
}
func main() {
Ic(foo(123));
// Outputs:
// ic| foo(123): 456
Ic(1 + 5);
// Outputs:
// ic| 1 + 5: 6
Ic(foo(123), 1 + 5);
// Outputs:
// ic| foo(123): 456, 1 + 5: 6
bar();
}
// Outputs:
// ic| main.go:12 in main.bar()go get -u "github.com/WAY29/icecream-go/icecream"
If you want to change the prefix of the output, you can call icecream.ConfigurePrefix("Hello| ") (by default the prefix is ic| ).
If you want to change how the result is outputted, you can call icecream.ConfigureOutputFunction(f). func may be type of func(s interface{}).
For example, if you want to log your messages to a file:
func logfile(s string) {
filePath := "log.log"
file, err := os.OpenFile(filePath, os.O_WRONLY|os.O_APPEND|os.O_CREATE, 0666)
if err != nil {
fmt.Println(err)
}
defer file.Close()
write := bufio.NewWriter(file)
write.WriteString(s)
write.Flush()
}
func main() {
ic.ConfigureOutputFunction(logfile)
ic.Ic(1, 2, 3)
}If you want to change how the value is outputted, you can call icecream.ConfigureArgToStringFunction(f), func may be type of func(v interface{}) interface{}.
For example, if you want to print more detail about a string:
func toString(v interface{}) interface{} {
rv := reflect.ValueOf(v)
if rv.Kind() == reflect.String {
return fmt.Sprintf("[!string %#v with length %d!]", v, len(v.(string)))
}
return fmt.Sprintf("%#v", v)
}
func main() {
s := "string"
ic.ConfigureArgToStringFunction(toString)
ic.Ic(s)
ic.Ic("test")
}If you want to add call's filename, line number, and parent function to ic's output, you can call icecream.ConfigureIncludeContext(true).
func main() {
ic.ConfigureIncludeContext(true)
ic.Ic(1, "asd")
}If you want to reset configuration, you can call icecream.ResetPrefix(),icecream.ResetOutputFunction(), icecream.ResetArgToStringFunction(),icecream.ResetIncludeContext() .
