# IDLizer

## Description

This folder contains collection of tools for analyzing and transformation of
.d.ts files, with aim of exposing ArkUI interfaces to more languages and runtimes.

## Tools available

### Peer generator

Prerequisites:

Add registry to the `.npmrc` file in the `$HOME` directory (`~/.npmrc`):
```text
registry=https://repo.huaweicloud.com/repository/npm/
@ohos:registry=https://repo.harmonyos.com/npm/
strict-ssl=false
lockfile=false
@azanat:registry=https://nexus.bz-openlab.ru:10443/repository/koala-npm/
@koalaui:registry=https://nexus.bz-openlab.ru:10443/repository/koala-npm/
@panda:registry=https://nexus.bz-openlab.ru:10443/repository/koala-npm/
//nexus.bz-openlab.ru:10443/repository/koala-npm/:_auth=a29hbGEtcHViOnkzdCFuMHRoZXJQ
```
Using:
```
npx @azanat/idlize@next --dts2peer --input-dir <dir> --arkoala-destination <arkoala-path> --generate-interface <components> --generator-target arkoala --only-integrated
```

Run:
```bash
cd idlize
git submodule update --init
git submodule update --remote
npm i
npm run compile
```

#### Generating libace interface files:

Given interface definitions it will produce for libace
  * For libace interface
    * arkoala_api.h header
    * api discovery code
    * component modifiers
    * etc

```bash
node . --dts2peer --input-dir sdk/component --generator-target libace --api-version 140
```

#### Generating high level language peer files:

Given interface definitions it will produce for Arkoala
  * For high language bindings (arkoala)
    * C++ glue code
    * high level language peer classes (TS, ArkTS, Java, etc)
    * etc


```bash
node . --dts2peer --input-dir sdk/component --generator-target arkoala --api-version 140
```


#### To test for full sdk

```bash
cd idlize
npm i
npm run check:peers:run
```

The output is in `out/ts-peers` directory

#### To test with a simple subset sdk

```bash
cd idlize
npm i
npm run check:subset:run
```

The output is in `out/ts-subset` directory

### .d.ts linter

 Tool checking that given folder (ArkUI interface declarations downloaded by Arkoala build by default) only contains reasonable set of TypeScript features allowed for usage in public interfaces.

To run

```bash
cd idlize
npm i
npm run compile
node . --linter --input-dir ../arkui-common/ohos-sdk-ets/openharmony/10/ets/component
```

Results are in `./<outputDir>/linter.txt` if  `--output-dir` parameter specified, otherwise printed to stdout.
If there are no unsuppressed errors - exit code is 1, otherwise it is 0.

Linter support whitelist files in JSON:
```json
{
    "suppressErrors": ["TYPE_ELEMENT_TYPE", "INDEX_SIGNATURE"],
    "suppressIdentifiers": {
        "cursorControl": ["NAMESPACE"]
    }
}
```
can be passed with `--linter-whitelist whitelist.json`.

### IDL generator

 Tool producing set of WebIDL-compatible interface definitions from .d.ts interface definitions.
 Still in progress, may produce incorrect IDL.

```bash
cd idlize
npm i
npm run compile
node . --dts2idl --input-dir ../arkui-common/ohos-sdk-ets/openharmony/10/ets/component --output-dir ./idl
```

Results are in `./idl/` folder.

### Typescript declaration files generator

Tool producing set of typescript declaration files from .idl interface definitions.

```bash
cd idlize
npm i
npm run compile
node . --idl2dts --input-dir ./test/from-idl/idl --output-dir ./dts
```

Results are in `./dts` folder.
