AppleWatch　Tide(潮汐) 実装を妄想

はじめに

イカダでの釣行するとき、潮汐が重要みたいです。
釣行に行く、三重県南伊勢町、愛知県知多市の２つで十分
湾内では、気圧や風の影響がでるので大まかな値で十分。気にしません

参考にする潮位プログラム

http://fmie.cside7.com/program/tide/download.html
この中の「TIDEソース公開版(C++)」を利用させていただきます
港データ(TD)は別途「TIDEforWIN」からいただきます

C言語の準備

Mac上のWin11にMS-DOS Playerを使ってTurbo Cをインストールしてみました。
- 階層：Mac　→　Win11　→　MS-DOS Player　→　Turbo C
  qiita.com
ヤッターと思いましたが。。。　　日本語が「化けとるみ」たいです
- 入手したTurbo Cですが、PC-98というNECのパソコン用みたいです。グーグルで調べたところ、「DOSBox-X」上でTurbo Cを使うと良いとのことでした
- 階層としては、Mac　　→　Win11　→　DOSBox-X　→　Turbo C　となります
- キーボードは Mac US　 →　win US →　win JP　　 →　win JP　となります。１つのキーボードでMacUS、WinUS、WinJPを切り替えれるものを以前作成してあり、とても役立っています。
  - yshigu.net
- dosbox-x.com
- インストールしたところ、デフォルトで日本語が正しく表示されましたが、枠線が文字化けしています。PC-98用に設定すれば良いかと思いますが、大きな問題ではありません。そのまま使います。

コンパイルしましたらエラーだらけですーーー！
- プログラムはマイクロソフト系のようです。テキスト画面とグラフィック画面の処理をTurbo C用に書き換えました。

結果確認
- HPデータ　
- 今回作成したデータ

AppleWatchで動かす準備
- 釣行先を決めました

ソフトの移行
- 元になる「int main( int argc, char *argv[] )」は次のようにしました
  - C言語で作られており、クラス化してないので見にくいです。
  - 暫くはデータの変化を順番に確認し、問題がなければ改良していきたいと考えて行きます。
  - 課題は沢山有ります
    - 配列の初期化　ｰ>　addで配列追加
    - 余分な「let」
    - IntとDoubleの使い分け
    - クラス化してデータの影響範囲指定する
  - func tideLineSet() -> [Double] {

- 取りあえず移行してみました。実務での使い方を妄想し、少しづつ詰めて行きます
  - デフォルト日付は、その日とする
  - 場所は最後に実施した場所とする
  - グラフを24時間アナログ表記してみる
  - など色々と妄想してみます。
