1.If the project don't have "LICENSE" in root dir, please define all the license files in this project in , OAT will check license files according to this rule.
tasklist(only for batch mode):
1. task: Define oat check thread, each task will start a new thread.
2. task name: Only an name, no practical effect.
3. task policy: Default policy for projects under this task, this field is required and the specified policy must defined in policylist.
4. task filter: Default filefilter for projects under this task, this field is required and the specified filefilter must defined in filefilterlist.
5. task project: Projects to be checked, the path field define the source root dir of the project.
policyList:
1. policy: All policyitems will be merged to default OAT.xml rules, the name of policy doesn't affect OAT check process.
2. policyitem: The fields type, name, path, desc is required, and the fields rule, group, filefilter is optional,the default value is:
<policyitem type="" name="" path="" desc="" rule="may" group="defaultGroup" filefilter="defaultPolicyFilter"/>
3. policyitem type:
"compatibility" is used to check license compatibility in the specified path;
"license" is used to check source license header in the specified path;
"copyright" is used to check source copyright header in the specified path;
"import" is used to check source dependency in the specified path, such as import ... ,include ...
"filetype" is used to check file type in the specified path, supported file types: archive, binary
"filename" is used to check whether the specified file exists in the specified path(support projectroot in default OAT.xml), supported file names: LICENSE, README, README.OpenSource
4. policyitem name: This field is used for define the license, copyright, "*" means match all, the "!" prefix means could not match this value. For example, "!GPL" means can not use GPL license.
5. policyitem path: This field is used for define the source file scope to apply this policyitem, the "!" prefix means exclude the files. For example, "!.*/lib/.*" means files in lib dir will be exclude while process this policyitem.
6. policyitem rule and group: These two fields are used together to merge policy results. "may" policyitems in the same group means any one in this group passed, the result will be passed.
7. policyitem filefilter: Used to bind filefilter which define filter rules.
8. filefilter: Filter rules, the type filename is used to filter file name, the type filepath is used to filter file path.

### Usage Guidelines<a name="section33105542504"></a>
You can run **node --expose-gc _your\_path_\_to/index.js \[options\] _your\_file_.js** to convert a JS file into an ARK bytecode file using ts2abc. If no parameter is specified for **\[options\]**, an ARK binary file is generated by default. The **index.js** file is the executable file generated after ts2abc compilation.

## 说明<a name="section0446154755015"></a>
ts2abc组件采用命令行交互方式，支持将JavaScript代码转换为方舟字节码文件，使其能够在方舟运行时上运行。支持Windows/Linux/MacOS平台。
### 使用说明<a name="section33105542504"></a>
ts2abc组件将JavaScript文件转换为方舟字节码文件，命令行格式为： node --expose-gc your\_path\_to/index.js \[options\] your\_file.js。当不输入任何option参数时，默认生成方舟二进制文件。其中index.js是ts2abc组件编译后的可执行文件。

## File overview:
```
es5_tests.txt: This file contains a list of ES5 test cases. If useful cases are found missing, you can add them as needed.
es2015_tests.txt: This file contains a full list of use cases of ES2015 except those filtered out with'es6id'. If useful cases are found missing, you can add them as needed.
skip_tests.json: This file contains a list of use cases that do not meet the requirements. If useful cases are found missing, you can add them according to the specified format.
```
## 1. Compile ts2abc and ark_js_vm project
```
./build.sh --product-name Hi3516DV300 --build-target ark_js_vm --build-target ark_ts2abc_build
```
## 2 Run test cases
### 2.1 Options
```
usage: run_test262.py [-h] [--dir DIR] [--file FILE] [--mode [{1,2,3}]]
[--es51] [--es2015 [{all,only}]] [--esnext]
[--engine FILE] [--babel] [--timeout TIMEOUT]
[--threads THREADS] [--hostArgs HOSTARGS]
[--ark-tool ARK_TOOL]
[--ark-frontend-tool ARK_FRONTEND_TOOL]
[--libs-dir LIBS_DIR]
[--ark-frontend [{ts2panda,es2panda}]]
optional arguments:
-h, --help show this help message and exit
--dir DIR Directory to test
--file FILE File to test
--mode [{1,2,3}] selection information as: 1: only default 2:
only strict mode 3: both default and strict mode
--es51 Run test262 ES5.1 version
--es2015 [{all,only}]
Run test262 - ES2015. all: Contains all use cases for
ES5 and ES2015, only: Only include use cases for
ES2015
--esnext Run test262 - ES.next.
--engine FILE Other engine binarys to run tests with
(as:d8,hermes,jsc,qjs...)
--babel Whether to use Babel conversion
--timeout TIMEOUT Set a custom test timeout in milliseconds !!!
--threads THREADS Run this many tests in parallel. Note that the browser
runners don't work great with t > 1.
--hostArgs HOSTARGS command-line arguments to pass to eshost host
--ark-tool ARK_TOOL ark's binary tool
--ark-frontend-tool ARK_FRONTEND_TOOL
ark frontend conversion tool
--libs-dir LIBS_DIR The path collection of dependent so has been divided
by':'
--ark-frontend [{ts2panda,es2panda}]
Choose one of them
```
### 2.2 run all the test cases
```
python3 test262/run_test262.py
```
### 2.3 run `es51` related test cases
```python
python3 test262/run_test262.py --es51
```
After the execution finished, a directory named `test_es51` is created under directory `test262/data` , which is used to store all `es51` cases.
### 2.4 run `es2015` related test cases
#### 2.4.1 only include use cases for ES2015
```python
python3 test262/run_test262.py --es2015 only
```
#### 2.4.2 contains all use cases for ES5 and ES2015
```python
python3 test262/run_test262.py --es2015 all
```
### 2.5 run single test case
```python
python3 test262/run_test262.py --file test262/data/test_es5/language/statements/break/12.8-1.js
```
### 2.6 run all the test cases under specified directory
```python
python3 test262/run_test262.py --dir test262/data/test_es5/language/statements
```
### 2.7 run single test case with other engines. Take d8 as an example
```python
python3 test262/run_test262.py --engine="/home/share/v8-code/v8/out.gn/x64.release/d8" --file test262/data/test_es5/language/statements/break/12.8-1.js
```
### 2.8 run single test case with `babel` conversion
```
python3 test262/run_test262.py --babel --file test262/data/test_es5/language/statements/break/12.8-1.js
```
### 2.9 Get test result
take the following code as an example:
```shell
zgy@lfgphicprd23154:/home/share/OpenHarmony2.0_20210604/ark/ts2abc$ python3 -B test262/run_test262.py --file test262/data/test_es51/language/statements/break/12.8-1.js

* `default` indicates `non-strict` mode, `strict mode` indicates the strict mode.
* After the execution finished, the following files are generated under directory `out/test262/` (you can specified it in `test262/config.py`):
```

```
`.abc` indicates the generated binary `abc` file.
`.err` indicates error occurs during the test.
`.fail/.pass` is the file saved after `js` file has been preprocessed.
The `result.txt` file is generated under directory `out/test262` to save statistics after the test finished.

### ts2panda
ts2panda aims to translate JavaScript source files into ARK bytecode which could be executed by the ARK runtime.
The whole converter could be splited into several phases.
* tsc(TypeScript compiler) automatically builds the AST for us
* translate TypeScript AST into panda instruction arrays
* apply several passes with the instruction arrays, including:
* [register allocator](doc/register_allocator.md)
* [intrinsic expander](doc/intrinsic_expander.md)
* [panda assembly dumper](doc/assembly_dumper.md)
* [panda binary dumper](doc/binary_dumper.md)
### Run a case
The whole ARK project needs to be built before running cases.
#### dump panda binary
```
node --expose-gc ../../out/release/clang_x64/ark/ark/build/src/index.js <your/path/to/case_jsFile> <--> <--output> <output-filename>
```
#### dump panda assembly
```
node --expose-gc ../../out/release/clang_x64/ark/ark/build/src/index.js <your/path/to/case_jsFile> --dump-assembly
```
