|
||
This section describes how to develop and test ARK runtime.
|
||
|
||
## HelloWorld<a name="section105987593810"></a>
|
||
|
||
### Preparations
|
||
|
||
1. Run the following command to compile ARK runtime:
|
||
|
||
```
|
||
./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages # arm platform and host side running tool
|
||
```
|
||
|
||
2. Run the following command to compile the ARK frontend:
|
||
|
||
x64：
|
||
```
|
||
./build.sh --product-name rk3568 --build-target ark_js_host_linux_tools_packages --build-target ark_ts2abc_build # arm平台和host端运行工具
|
||
```
|
||
|
||
arm64：
|
||
```
|
||
./build.sh --product-name ohos_arm64 --build-target ark_js_vm --build-target ld-musl-aarch64.so.1
|
||
```
|
||
|
||
arm32:
|
||
```
|
||
./build.sh --product-name rk3568 --build-target ark_js_runtime --build-target ld-musl-arm.so.1
|
||
```
|
||
|
||
**NOTE**: Run the compilation commands in the project root directory.
|
||
|
||
|
||
### Running **hello-world.js**
|
||
|
||
Create the **hello-world.js** file and write the following source code into the file:
|
||
|
||
```
|
||
print("Hello World!!!");
|
||
```
|
||
|
||
Run the **hello-world.js** file.
|
||
|
||
1. Use the ARK frontend to create the **hello-world.abc** file.
|
||
|
||
```
|
||
node --expose-gc /your code path/out/hispark_taurus/clang_x64/ark/ark/build/src/index.js hello-world.js
|
||
```
|
||
|
||
2. Run the **hello-world.abc** file.
|
||
1. Set the search path.
|
||
|
||
```
|
||
export LD_LIBRARY_PATH= out/hispark_taurus/clang_x64/ark/ark:out/hispark_taurus/clang_x64/ark/ark_js_runtime:out/hispark_taurus/clang_x64/global/i18n_standard:prebuilts/clang/ohos/linux-x86_64/llvm/lib
|
||
```
|
||
|
||
2. Run **ark\_js\_vm**.
|
||
|
||
```
|
||
/your code path/out/hispark_taurus/clang_x64/ark/ark_js_runtime/ark_js_vm hello-world.abc
|
||
```
|
||
|
||
The execution result is as follows:
|
||
|
||
```
|
||
Hello World!!!
|
||
```
|
||
|
||
**NOTE**: In the preceding command, _your code path_ indicates the source code directory.
|
||
|
||
### Disassembling **hello-world.abc**
|
||
|
||
Run the following command to export the result to the **output** file:
|
||
|
||
```
|
||
./your code path/out/hispark_taurus/clang_x64/ark/ark/ark_disasm hello-world.abc output
|
||
```
|
||
|
||
The output is as follows:
|
||
|
||
```
|
||
#
|
||
# source binary: hello-world.abc
|
||
#
|
||

|
||
builtin.acc
|
||
sta.dyn v5
|
||
builtin.idi "print", 0x0 // Load the print function.
|
||
sta.dyn v3
|
||
lda.str "Hello World!!!" // Load the Hello World!!! string.
|
||
sta.dyn v4
|
||
builtin.tern3 v3, v4 // Call the print function.
|
||
builtin.acc
|
||
}

### Example
|
||
|
||
- Run test case ES51.
|
||
|
||
```
|
||
python3 test262/run_test262.py --es51
|
||
```
|
||
|
||
- Run test case ES2015 only.
|
||
|
||
```
|
||
python3 test262/run_test262.py --es2015
|
||
```
|
||
|
||
- Run test case ES2021 only.
|
||
|
||
```
|
||
python3 test262/run_test262.py --es2021 only
|
||
|
||
- Run all ES2015 and ES51 and ES2021 test cases.
|
||
|
||
```
|
||
python3 test262/run_test262.py --es2021 all
|
||
```
|
||
|
||
- Run a test case.
|
||
|
||
```
|
||
python3 test262/run_test262.py --file test262/data/test_es5/language/statements/break/12.8-1.js
|
||
```
|
||
|
||
- Run all test cases in a directory.
|
||
|
||
```
|
||
python3 test262/run_test262.py --dir test262/data/test_es5/language/statements
|
||
```
|
||
|
||
|
||
- Use Babel to convert a test case into ES5 and then run the test case.
|
||
|
||
```
|
||
python3 test262/run_test262.py --babel --file test262/data/test_es5/language/statements/break/12.8-1.js
|
||
```
|
||
|
||
|
||
### Test Output
|
||
|
||
The results of all Test262 test cases are available in the **_Project root directory_/ark/ts2abc/out**. The test result in the shell is as follows:
|
||
|
||
```
