　現在私は予備校の寮でパートとして働いている。そこでは、退寮日を寮生全体に尋ね、その日時と部屋番号、そして寮費の納入方式（一括or二回or月払い）に応じて一月に引き落とされる金額が決定される。そこで私は、これをPerlで計算させようと決意した。四月からはこれぐらいできないといけないだろうし。今ならいっぱい失敗することもできるしね。プログラミングの初歩をかじったことのある人による、Perl体験日記。

<ul>
<li>
わかったこと <ul>
<li>
一括と二回は計算方法が同じ
</li>
<li>
一括と二回は1/16-2/15までは計算方法が同じ
</li>
</ul>
</li>
</ul>
<h4>
必要になるもの
</h4>
<p>
　計算方法の分析ができたので、次は引き落とし金額を求めるのに必要となるデータについて考えた。基本的には、
</p>
<ul>
<li>
必要なもの <ul>
<li>
B棟なのかC棟なのか？
</li>
<li>
部屋番号（後で個人を特定するために）
</li>
<li>
退寮日
</li>
<li>
12月分光熱費
</li>
</ul>
</li>
</ul>
<p>
ということが判明。『<a href="http://d.hatena.ne.jp/asin/4797336803" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://d.hatena.ne.jp/asin/4797336803', '新版Perl言語プログラミングレッスン入門編');">新版Perl言語プログラミングレッスン入門編</a>』を参考にCSVからデータを吸い上げる方法がわかる。だがここで、退寮日の記述方式が「月/日」という形式だと現状の自分の手には余ると判断。「退寮日」を「退寮する月」と「退寮する日」に分割することでこの問題の回避をはかった。従って、用意するCSVには
</p>
<ol>
<li>
CSVファイル <ol>
<li>
棟
</li>
<li>
部屋番号
</li>
<li>
退寮する月
</li>
<li>
退寮日
</li>
<li>
12月分光熱費
</li>
</ol>
</li>
</ol>
<p>
という構成にすることにした。このデータはExcelを使えば簡単に作れるだろうから、後はPerlで計算する部分を作る。<span class="footnote"><a href="/sirocco634/#f1" name="fn1" title="「Excelですべて作ってしまえば」という声もあるけれど、何十もの括弧で区切られる数式をいちいちやるのが面倒くさかったりして">*1</a></span>
</p>
<h4>
はまった部分
</h4>
<ul>
<li>
foreach構文の$_の部分（→$_に格納されるのってカウンタじゃなくて、配列の具体的な値なのですね。。。）
</li>
<li>
初歩的だけど、elseifじゃなかったんだ。。。elsif
</li>
<li>
Cygwin上のchompはうまく動かない（改行コードとか文字コードの違いかな？）
</li>
</ul>
