SharpC: A C Interpreter In C# - 0000
Update: igame@May/16/2019: Removed "ExternalFunction": it's redundent. So did the "RegesterExternalFunction". Renamed "InternalFunctions"directory(or namespace) to "ExtraFunctions". Removed Flex/Bison project which based on WinSDK 8.1. Renamed extra function "input"to "inputDlg". Fixed bug: "inputDlg"won't work.
新しいオブジェクト(my son)を維持する際,オブジェクトが休眠する暇を利用して習作を書いた.
塩少々.
通常、コンパイル原理またはコンパイル技術は、yaccまたはlexを使用して言語、式の解釈器またはコンパイラを実現することを推奨します.言語コンパイラや解釈器を実現する困難を考慮すると、多くの猿類はこのようなツールを使用します.しかし、本文はツールが登場する以前の時代にタイムスリップし、同時に金の指を開いた:c#、Flex、Bisonを持っていた.習作であるため、FlexやBisonではなく、c#を使用して簡単なc言語解釈器を手作業で作成しました.この解釈器はむやみにSharpCと命名された.c言語の次の特性の一部を実現しました.
とくせい
サポートの程度
説明
基本的なタイプ
char, short, int, float, struct
unsignedの場合、signedの区別は明らかではなく、constキーワードnow keyword「const」is supportedはサポートされていません.
関数＃カンスウ＃
サポート
不定パラメータ関数、再帰をサポート、ネスト定義をサポートします.
式＃シキ＃
サポートされていない場合のみ:さんげんオペレータ
カンマオペレータがテストされていません.
ししん
サポート
これは、メモリ操作をサポートすることを意味し、文字列をサポートすることを意味します.
せいぎょこうぞう
gotoのみサポートされていません
if/else,for,while,do/while,switch/case/default/break,return,continueを含む.
ビルド関数
malloc(), free(), print(), vararg(), varlen(), input(), InputDlg(), prompt(), confirm()
According updating of May-16-19, it's easier to add new functions into system.
その他
その他のc言語機能はすべてサポートされていません
例えば、#記号、macro、typedefなどです.
まず、最終結果を見てみましょう.このようなc言語テストコードについて:
SharpCの分析結果は以下の通りである.
解析によって生成された構文ツリーを印刷して、コードを復元します.
結果はソースコードとほぼ同じであることがわかります.
