Build Status Go Report Card Coverage Status GitHub release Discord

Our vision is to enable everyone to create production-level applications.

Easy to learn

  • Simple and easy to understand
  • Smaller syntax set than Python in best practices

Ready for large projects

  • Derived from Go and easy to build large projects from its good engineering foundation

The Go+ programming language is designed for engineering, STEM education, and data science.

  • For engineering: working in the simplest language that can be mastered by children.
  • For STEM education: studying an engineering language that can be used for work in the future.
  • For data science: communicating with engineers in the same language.

For more details, see Quick Start.

Command Style Code

Different from the function call style of most languages, Go+ recommends command style code:

println "Hello world"

To emphasize our preference for command style, we introduce echo as an alias for println:

echo "Hello world"

For more discussion on coding style, see https://tutorial.goplus.org/hello-world.

Go+ Classfiles

One language can change the whole world.
Go+ is a "DSL" for all domains.

Rob Pike once said that if he could only introduce one feature to Go, he would choose interface instead of goroutine. classfile is as important to Go+ as interface is to Go.

In the design philosophy of Go+, we do not recommend DSL (Domain Specific Language). But SDF (Specific Domain Friendliness) is very important. The Go+ philosophy about SDF is:

Don't define a language for specific domain.
Abstract domain knowledge for it.

Go+ introduces classfile to abstract domain knowledge.

Sound a bit abstract? Let's see some Go+ classfiles.

yap: Yet Another HTTP Web Framework

This classfile has the file suffix .yap.

Create a file named get.yap with the following content:

html `<html><body>Hello, YAP!</body></html>`

Execute the following commands:

gop mod init hello
gop get github.com/goplus/yap@latest
gop mod tidy
gop run .

A simplest web program is running now. At this time, if you visit http://localhost:8080, you will get:

Hello, YAP!

YAP uses filenames to define routes. get.yap's route is get "/" (GET homepage), and get_p_#id.yap's route is get "/p/:id" (In fact, the filename can also be get_p_:id.yap, but it is not recommended because : is not allowed to exist in filenames under Windows).

Let's create a file named get_p_#id.yap with the following content:

json {
	"id": ${id},
}

Execute gop run . and visit http://localhost:8080/p/123, you will get:

{"id": "123"}

See yap: Yet Another HTTP Web Framework for more details.

spx: A Go+ 2D Game Engine

Screen Shot1 Screen Shot2

Through this example you can learn how to implement dialogues between multiple actors.

Here are some codes in Kai.spx:

onStart => {
	say "Where do you come from?", 2
	broadcast "1"
}

onMsg "2", => {
	say "What's the climate like in your country?", 3
	broadcast "3"
}

We call onStart and onMsg to listen events. onStart is called when the program is started. And onMsg is called when someone calls broadcast to broadcast a message.

When the program starts, Kai says Where do you come from?, and then broadcasts the message 1. Who will recieve this message? Let's see codes in Jaime.spx:

onMsg "1", => {
	say "I come from England.", 2
	broadcast "2"
}

Yes, Jaime recieves the message 1 and says I come from England.. Then he broadcasts the message 2. Kai recieves it and says What's the climate like in your country?.

The following procedures are very similar. In this way you can implement dialogues between multiple actors.

See spx: A Go+ 2D Game Engine for more details.

gsh: Go+ DevOps Tools

Yes, now you can write shell script in Go+. It supports all shell commands.

Let's create a file named example.gsh and write the following code:

mkdir "testgsh"

Don't need a go.mod file, just enter gop run ./example.gsh directly to run.

See gsh: Go+ DevOps Tools for more details.
