PathMatchSpecの挙動

04 Sep

Windows上でワイルドカードを処理するAPIがPathMatchSpecである。

http://msdn.microsoft.com/en-us/library/bb773727(VS.85).aspx

しかしここに載っているサンプルがあまりにもセンスが悪い。

ということでテストコードを書いた。コードは後述。結果は以下。

&#034;somepath.html&#034; , &#034;somepath?html&#034; =&#062; true
&#034;somepath.html&#034; , &#034;&#034; =&#062; true
&#034;somepath.html&#034; , &#034;(null)&#034; =&#062; false
&#034;&#034; , &#034;&#042;&#034; =&#062; true
&#034;&#034; , &#034;a&#034; =&#062; false
&#034;somepath&#034; , &#034;&#042;.&#034; =&#062; false
&#034;somepath&#034; , &#034;&#042;.&#042;&#034; =&#062; true
&#034;hoge&#092;fuga.html&#034; , &#034;hoge&#042;&#034; =&#062; true
&#034;hoge&#092;fuga.html&#034; , &#034;hoge&#042;html&#034; =&#062; true
&#034;hoge&#092;fuga.html&#034; , &#034;hoge&#092;&#042;&#034; =&#062; true

"somepath.html" , "somepath?html" => true

"somepath.html" , "" => true

"somepath.html" , "(null)" => false

"" , "*" => true

"" , "a" => false

"somepath" , "*." => false

"somepath" , "*.*" => true

"hoge\fuga.html" , "hoge*" => true

"hoge\fuga.html" , "hoge*html" => true

"hoge\fuga.html" , "hoge\*" => true
