開発中に必要なときにエラーメッセージやその他の文字列をログに記録するColdFusionカスタムタグを作成しました。
私のカスタムタグはcfscriptで書かれています。私は私が得ることができるすべてを記録しようとします。したがって、「logMessage」に新しい文字列を追加するたびに、新しい行をログに記録したいと思います。
変数を含めようとしました
crlf = chr(10) & chr(13);
しかし、これは機能しません。writeLog（および対応するcflog）は新しい行を追加することになっていないと思いますか？
これが回避策を使用しようとした理由です（パイプが表示されるたびにwriteLog（）を使用）が、writeLog（）を実行するたびに非常に多くのメタデータがあるため、多くのオーバーヘッドが発生します。
これが私のスクリプトです。最初の行は、指定された属性（ "logType"やcfcatchオブジェクトなど）を評価し、定義されている場合は値を"logMessage"に追加します。
forループを含む最後の行を見下ろしてください。
<cfscript>
logMessageDelimiter="*******************************************************";
logMessage = "";
fileName = application.standard_log_path & application.server_name & "_standardLog";
logType = "information";
crlf = chr(10) & chr(13);
if(isDefined("attributes")){ //any attribute is given
if(isDefined("attributes.text")){ //a custom text is given

私は次のようにカスタムタグを使用します：
<cftry>
...some buggy code
<cfcatch>
<customTagName text="Hey, you've got an error!" file="myLogFile" type="e" catch="#cfcatch#">
</cfcatch>
</cftry>
ログに次の出力が表示されます（切り捨てられます）。

それで、あなたはしますか？writeLog（）を何度も実行せずに、新しい行を取得する方法はありますか？
私はこのような結果を見たいです：
"Information","ajp-bio-8013-exec-37118","02/11/13","14:26:09","SYS_MYSYS","LogMessage: Hey, you've got an error!"

メソッドを使用してファイルに書き込むこともできますが、それも最善の方法ではないと思いますね。さらに、アプリケーション内からColdFusionの標準のログフォルダ（例：/ path / to / coldfusion / instancename / logs / myLogFolder）に書き込めませんか？！
ログファイルに構造を設定する方法はありますか？アイデアはありますか？
