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

Go

go get kcl-lang.io/lib

Write the Code

package main

import (
	"kcl-lang.io/lib/go/install"
)

func main() {
    path = "path/to/install/lib"
    _ := install.InstallKclvm(path)
}

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>0.10.0-alpha.1-SNAPSHOT</version>
</dependency>

Write the code

import com.kcl.api.API;
import com.kcl.api.Spec.ExecProgram_Args;
import com.kcl.api.Spec.ExecProgram_Result;

public class ExecProgramTest {
    public static void main(String[] args) throws Exception {
        API api = new API();
        ExecProgram_Result result = api
                .execProgram(ExecProgram_Args.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 ExecProgram_Args();
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.ExecProgram_Args(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();

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        v0.10.0-alpha.1
  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();
    auto files = rust::Vec<rust::String>();
    files.push_back(rust::String("../test_data/schema.k"));
    args.k_filename_list = files;
    auto result = kcl_lib::exec_program(args);
    std::cout << result.yaml_result.c_str() << std::endl;
}
