GoPlus - The Go+ language for data science

Build Status Go Report Card GitHub release Coverage Status REPL Playground VSCode GoDoc

NOTE: Go+ is still under heavy developement. Please don't use it in production environment.

Summary about Go+

What are mainly impressions about Go+?

  • A static typed language.
  • Fully compatible with the Go language.
  • Script-like style, and more readable code for data science than Go.

For example, the following is legal Go+ source code:

a := [1, 2, 3.4]
println(a)

How do we do this in the Go language?

package main

func main() {
    a := []float64{1, 2, 3.4}
    println(a)
}

Of course, we don't only do less-typing things.

For example, we support list comprehension, which makes data processing easier.

a := [1, 3, 5, 7, 11]
b := [x*x for x <- a, x > 3]
println(b) // output: [25 49 121]

mapData := {"Hi": 1, "Hello": 2, "Go+": 3}
reverseMap := {v: k for k, v <- mapData}
println(reverseMap) // output: map[1:Hi 2:Hello 3:Go+]

We will keep Go+ simple. This is why we call it Go+, not Go++.

Less is exponentially more.

It's for Go, and it's also for Go+.

Compatibility with Go

All Go features will be supported (including partially support cgo, see below).

All Go packages (even these packages use cgo) can be imported by Go+.

import (
    "fmt"
    "strings"
)

x := strings.NewReplacer("?", "!").Replace("hello, world???")
fmt.Println("x:", x)

Be interested in how it works? See Import Go packages in Go+ programs.

Also, all Go+ packages can be converted into Go packages and imported in Go programs.

First, let's make a directory named tutorial/14-Using-goplus-in-Go.

Then write a Go+ package named foo in it:

package foo

func ReverseMap(m map[string]int) map[int]string {
    return {v: k for k, v <- m}
}

Then use it in a Go package:

package main

import (
	"fmt"

	"github.com/goplus/gop/tutorial/14-Using-goplus-in-Go/foo"
)

func main() {
	rmap := foo.ReverseMap(map[string]int{"Hi": 1, "Hello": 2})
	fmt.Println(rmap)
}

How to compile this example?

gop go tutorial/ # Convert all Go+ packages in tutorial/ into Go packages
go install ./...

Or:

gop install ./... # Convert Go+ packages and go install ./...

Go+ features

Bytecode vs. Go code

Go+ supports bytecode backend and Go code generation.

When we use gop go or gop install command, it generates Go code to covert Go+ package into Go packages.

When we use gop run command, it doesn't call go run command. It generates bytecode to execute.

In bytecode mode, Go+ doesn't support cgo. However, in Go-code-generation mode, Go+ fully supports cgo.

Commands

gop run         # Run a Go+ program
gop repl        # Run Go+ in REPL/Console mode
gop go [-test]  # Convert Go+ packages into Go packages. If -test specified, it tests related packages.
gop fmt         # Format Go+ packages
gop export      # Export Go packages for Go+ programs

See https://github.com/goplus/gop/wiki/Commands for details.

Note:

  • gop go -test <gopSrcDir> converts Go+ packages into Go packages, and for every package, it call go run <gopPkgDir>/gop_autogen.go and gop run -quiet <gopPkgDir> to compare their outputs. If their outputs aren't equal, the test case fails.

Rational number: bigint, bigrat, bigfloat

We introduce the rational number as native Go+ types. We use suffix r to denote rational literals. For example, (1r << 200) means a big int whose value is equal to 2200. And 4/5r means the rational constant 4/5.

a := 1r << 65   // bigint, large than int64
b := 4/5r       // bigrat
c := b - 1/3r + 3 * 1/2r
println(a, b, c)

Map literal

x := {"Hello": 1, "xsw": 3.4} // map[string]float64
y := {"Hello": 1, "xsw": "Go+"} // map[string]interface{}
z := {"Hello": 1, "xsw": 3} // map[string]int
empty := {} // map[string]interface{}

Slice literal

x := [1, 3.4] // []float64
y := [1] // []int
z := [1+2i, "xsw"] // []interface{}
a := [1, 3.4, 3+4i] // []complex128
b := [5+6i] // []complex128
c := ["xsw", 3] // []interface{}
empty := [] // []interface{}

List comprehension

a := [x*x for x <- [1, 3, 5, 7, 11]]
b := [x*x for x <- [1, 3, 5, 7, 11], x > 3]
c := [i+v for i, v <- [1, 3, 5, 7, 11], i%2 == 1]
d := [k+","+s for k, s <- {"Hello": "xsw", "Hi": "Go+"}]

arr := [1, 2, 3, 4, 5, 6]
e := [[a, b] for a <- arr, a < b for b <- arr, b > 2]

x := {x: i for i, x <- [1, 3, 5, 7, 11]}
y := {x: i for i, x <- [1, 3, 5, 7, 11], i%2 == 1}
z := {v: k for k, v <- {1: "Hello", 3: "Hi", 5: "xsw", 7: "Go+"}, k > 3}

Select data from a collection

type student struct {
    name  string
    score int
}

students := [student{"Ken", 90}, student{"Jason", 80}, student{"Lily", 85}]

unknownScore, ok := {x.score for x <- students, x.name == "Unknown"}
jasonScore := {x.score for x <- students, x.name == "Jason"}

println(unknownScore, ok) // output: 0 false
println(jasonScore) // output: 80

For loop

sum := 0
for x <- [1, 3, 5, 7, 11, 13, 17], x > 3 {
    sum += x
}

Error handling

We reinvent the error handling specification in Go+. We call them ErrWrap expressions:

expr! // panic if err
expr? // return if err
expr?:defval // use defval if err

How to use them? Here is an example:

import (
	"strconv"
)

func add(x, y string) (int, error) {
	return strconv.Atoi(x)? + strconv.Atoi(y)?, nil
}

func addSafe(x, y string) int {
	return strconv.Atoi(x)?:0 + strconv.Atoi(y)?:0
}

println(`add("100", "23"):`, add("100", "23")!)

sum, err := add("10", "abc")
println(`add("10", "abc"):`, sum, err)

println(`addSafe("10", "abc"):`, addSafe("10", "abc"))

The output of this example is:

add("100", "23"): 123
add("10", "abc"): 0 strconv.Atoi: parsing "abc": invalid syntax

===> errors stack:
main.add("10", "abc")
	/Users/xsw/goplus/tutorial/15-ErrWrap/err_wrap.gop:6 strconv.Atoi(y)?

addSafe("10", "abc"): 10

Compared to corresponding Go code, It is clear and more readable.

And the most interesting thing is, the return error contains the full error stack. When we got an error, it is very easy to position what the root cause is.

How these ErrWrap expressions work? See Error Handling for more information.

Auto property

Let's see an example written in Go+:

import "github.com/goplus/gop/ast/goptest"

doc := goptest.New(`... Go+ code ...`)!

println(doc.Any().FuncDecl().Name())

In many languages, there is a concept named property who has get and set methods.

Suppose we have get property, the above example will be:

import "github.com/goplus/gop/ast/goptest"

doc := goptest.New(`... Go+ code ...`)!

println(doc.any.funcDecl.name)

In Go+, we introduce a concept named auto property. It is a get property, but is implemented automatically. If we have a method named Bar(), then we will have a get property named bar at the same time.

Unix shebang

You can use Go+ programs as shell scripts now. For example:

#!/usr/bin/env -S gop run

println("Hello, Go+")

println(1r << 129)
println(1/3r + 2/7r*2)

arr := [1, 3, 5, 7, 11, 13, 17, 19]
println(arr)
println([x*x for x <- arr, x > 3])

m := {"Hi": 1, "Go+": 2}
println(m)
println({v: k for k, v <- m})
println([k for k, _ <- m])
println([v for v <- m])

    Feature requests

    在今年 ecug 大会前(2020.12.30 日前),完成 qlang v6 (alias v1.6) 版本。

    核心变化:

    • 完全推翻重来,从动态类型转向静态类型!
    • 完全兼容 Go 语言文法。
    • 在 Go 语言兼容基础上,保留当初 qlang 动态类型版本的重要特性。比如:
    a := [1, 2, 3.4]
    // 等价于 Go 中的  a := []float64{1, 2, 3.4}
    
    b := {"a": 1, "b": 3.0}
    // 等价于  b := map[string]float64{"a": 1, "b": 3.0}
    
    c := {"a": 1, "b": "Hello"}
    // 等价于 c := map[string]interface{}{"a": 1, "b": "Hello"}
    

    当然也会放弃一些特性,比如:

    a = 1   // 需要改为 a := 1,放弃该特性是为了让编译器更好地发现变量名冲突。

    Additional Notes

    If i remove go.mod file at the target dir, then gop run command will successed.

    If i readd go.mod file and remove auto generated gop_autogen.go file, then gop run will failed again.

    The above experiment should not be run under gop repo dir, any other dir which has a go.mod file will get such error.

    exec/bytecode bug: swap struct slice element

    In bytecode mode (https://jsplay.goplus.org/):

    type student struct {
        name	string
        age		int
        score	int
    }
    
    a := [student{"A", 13, 90}, student{"B", 12, 72}, student{"C", 12, 85}]
    a[1], a[2] = a[2], a[1]
    
    println(a)
    

    It got:

    [{A 13 90} {B 12 72} {B 12 72}]
    

    But int slice is good:

    a := [1, 3, 2]
    a[1], a[2] = a[2], a[1]
    
    println(a)
    

    It got:
