ClangNet : libclangの.NET(C#) Bindingを作りました

## まえがき
LLVM/Clangに同梱されているlibclangの.NET(C#) Bindingライブラリ(ClangNet)を作成しました。
libclangはC/C++/Objective-Cソースコードの解析や自動補完機能を提供する高レベルのAPIで、オリジナルはC言語ベースのAPIが提供されています。

libclangのC# Bindingはいくつかありますが、最新のVer.8.0に対応したものがなかったので作ってみました。

なお、以下の環境でビルドおよび簡易的な動作確認を行っています。

- Visual Studio 2019 Community
- Visual Studio for Mac

※ すべての機能に対するテストは出来ていませんので、不具合等ありましたらご連絡いただければと思います。

## ダウンロード先
### GitHub
ClangNet本体、動作サンプルを含むソースコードは[GitHub](https://github.com/an-embedded-engineer/ClangNet)に置いてあります。

### NuGet
ClangNetをプロジェクトに組み込んで使いたい場合は、[NuGet](https://www.nuget.org/packages/ClangNet/)からパッケージをインストールしてください。

### libclang
libclang本体はプロジェクトに含まれていませんので、[公式](http://releases.llvm.org/download.html)などから取得してください。
Windows版の組み込み方法は↓の動作サンプルの項で説明しています。

## 動作サンプル
ここでは、Windowsで動作させるための手順を紹介していきます。
MacやLinuxでも基本的には同じようにして動作させることができると思います。
(違うのはlibclangの準備くらいだと思います)

### 事前準備
##### LLVM/Clangインストール
libclang本体を入手するために、公式で配布されているインストーラを使ってLLVM/Clangをインストールします。
libclang本体もその中に含まれています。

1. [公式](http://releases.llvm.org/download.html)から、最新Ver(現在は8.0.1)のWindows 64bit用のインストーラを[ダウンロード](https://github.com/llvm/llvm-project/releases/download/llvmorg-8.0.1/LLVM-8.0.1-win64.exe)します
2. ダウンロードしたインストーラ(LLVM-XX-Win64.exe)をダブルクリックし、インストーラを起動します
3. インストールウィザードに従ってLLVM/Clangをインストールします(特に設定変更などは不要です)

インストールが完了すると、以下のパスにlibclang本体が格納されています。
C:\Program Files\LLVM\bin\libclang.dll

##### プロジェクト作成

1. Visual StudioでC#プロジェクト[^1]を作成します
2. Visual StudioからNuGetパッケージマネージャでClangNetを検索してインストールします
![SnapCrab_NoName_2019-9-8_5-16-20_No-00.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/64578/62b0656c-5e12-683b-9c22-6e976a7c44ae.png)
3. ↑でインストールしたlibclang.dllをVisual Studioプロジェクトディレクトリ内にコピーします
4. libclang.dllのプロパティから「出力ディレクトリにコピー」を「常にコピーする」に変更します[^2]
![SnapCrab_NoName_2019-9-8_5-21-57_No-00.png](https://qiita-image-store.s3.ap-northeast-1.amazonaws.com/0/64578/07a6fec3-ccb9-3550-f396-8f58129e2cfd.png)


[^1]: ClangNet自体は.NET Standardで作成していますので、作成するプロジェクトは.NET Framework/.NET Coreのどちらでも利用可能です
[^2]: これで、プロジェクトビルド時に、実行ファイルと同じディレクトリにlibclangがコピーされます

### 解析対象ソース
次に、解析対象となるC/C++のソースコードを準備します。
今回は、クラスや継承、テンプレートなどを使った↓のようなソースを準備しました。
※ 解析対象ソースの中身の説明については割愛します

ソースファイルは、実行ファイルと同じディレクトリのCodeディレクトリ配下に配置します。
libclangと同様に、プロジェクトディレクトリに配置して、「出力ディレクトリにコピー」を設定しておくと良いと思います。

```cpp:Code/inc/Calculator.h
#pragma once

        return a - b;
    case Mode::Mul:
        return a * b;
    case Mode::Div:
        return a / b;
    case Mode::Mod:

```

### ClangNetによる解析コードサンプル
今回は、「main.cpp」ファイルを解析して、以下の情報を出力するサンプルを作成しました。

- 抽象構文木(Abstract Syntax Tree:AST)を再帰的にパースして、各要素の種類、名前、ソース位置情報を出力する
- インクルードしているヘッダファイルのパスと階層構造を出力する

## あとがき
気が向いたら、他の実用例のサンプルなども書いていきたいと思います。

 - より詳しい情報の取得方法
 - コールツリーの出力方法
 - etc...
