Specification

No package main

package main

func f() {
}

will be converted into:

func f() {
}

No func main

package main

func main() {
    a := 0
}

will be converted into:

a := 0

Replace fmt.Print to builtin

import "fmt"

n, err := fmt.Println("Hello world")

will be converted into:

n, err := echo("Hello world")

Note:

• Convert fmt.Errorf => errorf
• Convert fmt.Fprint => fprint
• Convert fmt.Fprintf => fprintf
• Convert fmt.Fprintln => fprintln
• Convert fmt.Print => print
• Convert fmt.Printf => printf
• Convert fmt.Println => echo
• Convert fmt.Sprint => sprint
• Convert fmt.Sprintf => sprintf
• Convert fmt.Sprintln => sprintln

Command style first

import "fmt"

fmt.Println()
fmt.Println(fmt.Println("Hello world"))

will be converted into:

echo
echo echo("Hello world")

Note:

• Only the outermost function call statement is converted into command style. So fmt.Println(fmt.Println("Hello world")) is converted into echo echo("Hello world"), not echo echo "Hello world".

pkg.Fncall starting with lowercase

import "math"

echo math.Sin(math.Pi/3)

will be converted into:

echo math.sin(math.Pi/3)

Funclit of params convert to lambda in fncall (skip named results)

echo(demo(func(n int) int {
	return n+100
}))

echo(demo(func(n int) (v int) {
	return n+100
}))

onStart(func() {
	echo("start")
})

will be converted into:

echo demo(n => n + 100)

echo demo(func(n int) (v int) {
	return n + 100
})

onStart => {
	echo "start"
}
