KCL Multiple Language Bindings and SDKs

This repo mainly includes the binding of the low-level API and spec of the KCL language core, and the SDKs of various languages are based on this to encapsulate higher-level APIs.

Bindings

Rust

cargo add --git https://github.com/kcl-lang/lib

Write the Code

use kcl_lang::*;
use anyhow::Result;

fn main() -> Result<()> {
    let api = API::default();
    let args = &ExecProgramArgs {
        k_filename_list: vec!["main.k".to_string()],
        k_code_list: vec!["a = 1".to_string()],
        ..Default::default()
    };
    let exec_result = api.exec_program(args)?;
    println!("{}", exec_result.yaml_result);
    Ok(())
}

More Rust APIs can be found here. If you want to use the sub crate of KCL Rust core, you can run the following command.

# Take the kcl-runtime as an example.
cargo add --git https://github.com/kcl-lang/kcl kcl-runtime

Go

go get kcl-lang.io/lib

Write the Code

package main

import (
	"fmt"

	"kcl-lang.io/lib/go/api"
	"kcl-lang.io/lib/go/native"
)

func main() {
	client := native.NewNativeServiceClient()
	result, err := client.ExecProgram(&api.ExecProgramArgs{
		KFilenameList: []string{"main.k"},
		KCodeList:     []string{"a = 1"},
	})
	if err != nil {
		t.Fatal(err)
	}
	fmt.Println(result.YamlResult)
}

Full Go SDK can be found here, which depends on the kcl-lang/lib Go bindings.

Java

Refer to this to configure your Maven; set up your GitHub account and Token in the settings.xml.

Maven

In your project's pom.xml, configure our repository as follows:

<repositories>
    <repository>
        <id>github</id>
        <url>https://maven.pkg.github.com/kcl-lang/*</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

This way you'll be able to import the above dependency to use the SDK.

<dependency>
    <groupId>com.kcl</groupId>
    <artifactId>kcl-lib</artifactId>
    <version>0.12.3</version>
</dependency>

Write the code

import com.kcl.api.API;
import com.kcl.api.Spec.ExecProgramArgs;
import com.kcl.api.Spec.ExecProgramResult;

public class ExecProgramTest {
    public static void main(String[] args) throws Exception {
        API api = new API();
        ExecProgramResult result = api
                .execProgram(ExecProgramArgs.newBuilder().addKFilenameList("path/to/kcl.k").build());
        System.out.println(result.getYamlResult());
    }
}

.NET

dotnet add package KclLib

Write the code

using KclLib.API;

var api = new API();
var execArgs = new ExecProgramArgs();
var path = Path.Combine("test_data", "schema.k");
execArgs.KFilenameList.Add(path);
var result = api.ExecProgram(execArgs);
Console.WriteLine(result.YamlResult);

Python

python3 -m pip install kcl-lib

Write the code

import kcl_lib.api as api

args = api.ExecProgramArgs(k_filename_list=["./tests/test_data/schema.k"])
api = api.API()
result = api.exec_program(args)
print(result.yaml_result)

Node.js

npm install kcl-lib

Write the code

import { execProgram, ExecProgramArgs } from 'kcl-lib'

function main() {
  const result = execProgram(new ExecProgramArgs(['__test__/test_data/schema.k']))
  console.log(result.yamlResult)
}

main();

Kotlin

<dependency>
    <groupId>com.kcl</groupId>
    <artifactId>kcl-lib</artifactId>
    <version>0.12.3</version>
</dependency>

Write the code

import com.kcl.api.API
import com.kcl.api.execProgramArgs

val args = execProgramArgs { kFilenameList += "schema.k" }
val api = API()
val result = api.execProgram(args)

Swift

import KclLib

let api = API()
var execArgs = ExecProgramArgs()
execArgs.kFilenameList.append("schema.k")
let result = try api.execProgram(execArgs)

C++

For CMake, you can use FetchContent to add KCL C++ Lib to your project.

FetchContent_Declare(
  kcl-lib
  GIT_REPOSITORY https://github.com/kcl-lang/lib.git
  GIT_TAG        v0.12.3
  SOURCE_SUBDIR  cpp
)
FetchContent_MakeAvailable(kcl-lib)

Or you can download the source code and add it to your project.

mkdir third_party
cd third_party
git clone https://github.com/kcl-lang/lib.git

add_subdirectory(third_party/lib/cpp)

target_link_libraries(your_target kcl-lib-cpp)

Write the code

#include "kcl_lib.hpp"
#include <iostream>

int main()
{
    auto args = kcl_lib::ExecProgramArgs {
        .k_filename_list = { "../test_data/schema.k" },
    };
    auto result = kcl_lib::exec_program(args);
    std::cout << result.yaml_result.c_str() << std::endl;
    return 0;
}
