|

Go bindings to QuickJS: a fast, small, and embeddable ES2020 JavaScript interpreter.
|
||||
|
||||
|
||||
## Features
|
||||
* Evaluate script
|
||||
* Compile script into bytecode and Eval from bytecode
|
||||
* Operate JavaScript values and objects in Go
|
||||
* Bind Go function to JavaScript async/sync function
|
||||
* Simple exception throwing and catching
|
||||
|
||||
## Guidelines
|
||||
|
||||
1. Free `quickjs.Runtime` and `quickjs.Context` once you are done using them.
|
||||
2. Free `quickjs.Value`'s returned by `Eval()` and `EvalFile()`. All other values do not need to be freed, as they get garbage-collected.
|
||||
3. Use `ExecuteAllPendingJobs` wait for promise/job result after you using promise/job
|
||||
4. You may access the stacktrace of an error returned by `Eval()` or `EvalFile()` by casting it to a `*quickjs.Error`.
|
||||
5. Make new copies of arguments should you want to return them in functions you created.
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
import "apigo.cloud/git/apigo/qjs"
|
||||
```
|
||||
|
||||
### Run a script
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"apigo.cloud/git/apigo/qjs"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new runtime
|
||||
rt := quickjs.NewRuntime()
|
||||
defer rt.Close()
|
||||
|
||||
// Create a new context
|
||||
ctx := rt.NewContext()
|
||||
defer ctx.Close()
|
||||
|
||||
ret, err := ctx.Eval("'Hello ' + 'QuickJS!'")
|
||||
if err != nil {
|
||||
println(err.Error())
|
||||
}
|
||||
fmt.Println(ret.String())
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
### Get/Set Javascript Object
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"apigo.cloud/git/apigo/qjs"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new runtime
|
||||
rt := quickjs.NewRuntime()
|
||||
defer rt.Close()
|
||||
|
||||
// Create a new context
|
||||
ctx := rt.NewContext()
|
||||
defer ctx.Close()
|
||||
|
||||
test := ctx.Object()
|
||||
test.Set("A", ctx.String("String A"))
|
||||
test.Set("B", ctx.String("String B"))
|
||||
test.Set("C", ctx.String("String C"))
|
||||
ctx.Globals().Set("test", test)
|
||||
|
||||
ret, _ := ctx.Eval(`Object.keys(test).map(key => test[key]).join(" ")`)
|
||||
defer ret.Free()
|
||||
fmt.Println(ret.String())
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
### Bind Go Funtion to Javascript async/sync function
|
||||
```go
|
||||
package main
|
||||
import "apigo.cloud/git/apigo/qjs"
|
||||
|
||||

rt := quickjs.NewRuntime()
|
||||
defer rt.Close()
|
||||
|
||||
// Create a new context
|
||||
ctx := rt.NewContext()
|
||||
defer ctx.Close()
|
||||
|
||||
// Create a new object
|
||||
test := ctx.Object()
|
||||
defer test.Free()
|
||||
// bind properties to the object
|
||||
test.Set("A", test.Context().String("String A"))
|
||||
test.Set("B", ctx.Int32(0))
|
||||
test.Set("C", ctx.Bool(false))
|
||||
// bind go function to js object
|
||||
test.Set("hello", ctx.Function(func(ctx *quickjs.Context, this quickjs.Value, args []quickjs.Value) quickjs.Value {
|
||||
return ctx.String("Hello " + args[0].String())
|
||||
}))
|
||||
|
||||
// bind "test" object to global object
|
||||
ctx.Globals().Set("test", test)
|
||||
|
||||
// call js function by js
|
||||
js_ret, _ := ctx.Eval(`test.hello("Javascript!")`)
|
||||
fmt.Println(js_ret.String())
|
||||
|
||||
// call js function by go
|
||||
go_ret := ctx.Globals().Get("test").Call("hello", ctx.String("Golang!"))
|
||||
fmt.Println(go_ret.String())
|
||||
|
||||
//bind go function to Javascript async function
|
||||
ctx.Globals().Set("testAsync", ctx.AsyncFunction(func(ctx *quickjs.Context, this quickjs.Value, promise quickjs.Value, args []quickjs.Value) {
|
||||
promise.Call("resolve", ctx.String("Hello Async Function!"))
|
||||
}))
|
||||
|
||||
ret, _ := ctx.Eval(`
|
||||
var ret;
|
||||
testAsync().then(v => ret = v)
|
||||
`)
|
||||
defer ret.Free()
|
||||
|
||||
// wait for promise resolve
|
||||
rt.ExecuteAllPendingJobs()
|
||||
|
||||
//get promise result
|
||||
asyncRet, _ := ctx.Eval("ret")
|
||||
defer asyncRet.Free()
|
||||
|
||||
fmt.Println(asyncRet.String())
|
||||
|
||||
// Output:
|
||||
// Hello Javascript!
|
||||
// Hello Golang!
|
||||
// Hello Async Function!
|
||||
}
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|

||||
// raise error
|
||||
return ctx.ThrowError(expected)
|
||||
})
|
||||
|
||||
_, actual := ctx.Eval("A()")
|
||||
fmt.Println(actual.Error())

[English](README.md) | 简体中文
|

Go 语言的QuickJS绑定库：快速、小型、可嵌入的ES2020 JavaScript解释器。
|
||||
|
||||
## 功能
|
||||
* 执行javascript脚本
|
||||
* 编译javascript脚本到字节码并执行字节码
|
||||
* 在 Go 中操作 JavaScript 值和对象
|
||||
* 绑定 Go 函数到 JavaScript 同步函数和异步函数
|
||||
* 简单的异常抛出和捕获
|
||||
|
||||
## 指南
|
||||
|
||||
1. 在使用完毕后，请记得关闭 `quickjs.Runtime` 和 `quickjs.Context`。
|
||||
2. 请记得关闭由 `Eval()` 和 `EvalFile()` 返回的 `quickjs.Value`。其他值不需要关闭，因为它们会被垃圾回收。
|
||||
3. 如果你使用了promise 或 async function，请使用 `ExecuteAllPendingJobs` 等待所有的promise/job结果。
|
||||
4. You may access the stacktrace of an error returned by `Eval()` or `EvalFile()` by casting it to a `*quickjs.Error`.
|
||||
4. 如果`Eval()` 或 `EvalFile()`返回了错误，可强制转换为`*quickjs.Error`以读取错误的堆栈信息。
|
||||
5. 如果你想在函数中返回参数，请在函数中复制参数。
|
||||
|
||||
## 用法
|
||||
|
||||
```go
|
||||
import "apigo.cloud/git/apigo/qjs"
|
||||
```
|
||||
|
||||
### 执行javascript脚本
|
||||
```go

||||
package main
|
||||
|
||||
import (
|
||||
"fmt"

|
||||
"apigo.cloud/git/apigo/qjs"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Create a new runtime
|
||||
rt := quickjs.NewRuntime()
|
||||
defer rt.Close()
|
||||
|
||||
// Create a new context
|
||||
ctx := rt.NewContext()
|
||||
defer ctx.Close()
|
||||
|
||||
ret, err := ctx.Eval("'Hello ' + 'QuickJS!'")
|
||||
if err != nil {
|
||||
println(err.Error())
|
