ArkCompiler Development

Introduction

ArkCompiler is a unified programming platform. Its key components include a compiler, toolchain, and runtime. ArkCompiler supports compilation and running of high-level programming languages on the multi-chip platform and accelerates the running of applications and services on mobile phones, PCs, tablets, TVs, automobiles, and smart wearables.

Environment Setup

Ubuntu 18.04 or later is recommended.

Install dependent tools. shell sudo apt-get update && sudo apt-get install python ruby python3-pip git-lfs gcc-multilib g++-multilib zlib1g-dev libc++1 curl nodejs
Install the repo tool. shell mkdir ~/bin/ curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > ~/bin/repo chmod a+x ~/bin/repo export PATH=~/bin:$PATH pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple requests

Download source code.

repo init -u https://gitee.com/ark-standalone-build/manifest.git -b master
repo sync -c -j8
repo forall -c 'git lfs pull'

Install the compiler and binary tool.
```
./prebuilts_download.sh
```

How to Develop

Create the build products ark_js_vm and es2panda.
```
python ark.py x64.release
```
- ark_js_vm: executable program for running .abc files.
- es2panda: tool that converts ArkTS files into ArkCompiler bytecode files.

Use es2panda to convert a TypeScript file to an .abc file.

out/x64.release/arkcompiler/ets_frontend/es2abc helloworld.ts

Code snippet of the TypeScript case file helloworld.ts:

declare function print(arg:string):string;
print('Hello world!');

Run the generated .abc file.
```
out/x64.release/arkcompiler/ets_runtime/ark_js_vm helloworld.abc
```
.abc file: ArkCompiler bytecode file.

The execution output is as follows:
```
Hello world!
```
