として、 unmanagedResourceDirectories in Compile <<= (sourceDirectory, selectedProfile, unmanagedResourceDirectories in Compile)
((dir, env, res) => env.map((dir / _.name / "resources")).toSeq ++ res),
unmanagedResources in Compile~= (_.groupBy((_: java.io.File).getName).map(_._2.head).toSeq),
リソースディレクトリの設定時に振り分け。さらに、リソースファイル設定時に一意になるようグループ化しているようなしていないような・・・いまいち何をやっているかわからないが完成・・・
final def <<=(app: Initialize[T]): Setting[T]なるほど、Initialize[T] を受け取る。 unmanagedResourceDirectories は SettingKey[Seq[File]] なので、右辺の
(sourceDirectory, selectedProfile, unmanagedResourceDirectories in Compile)
((dir, env, res) => env.map((dir / _.name / "resources")).toSeq ++ res)
は、Initialize[Seq[File]] を返すのであろう。(sourceDirectory, selectedProfile, unmanagedResourceDirectories in Compile)(なんかの処理)つまり、
(タプル).apply(なんかの処理)のように見えるが、タプルに対してそんなことできるのか・・・おそらくは暗黙の型変換・・・
implicit def t3ToApp3[A,B,C](t3: (Initialize[A], Initialize[B], Initialize[C]) ): Apply3[A,B,C] = new Apply3(t3)というのを発見。さらに、Apply3 をみると、
def apply[T](z: (A,B,C) => T) = Project.app( k3(t3) )( hf3(z) )となっている。さらに、object Project の API ドキュメントに、Init[Scope] に app の定義があり
def app[HL <: HList, T](inputs: KList[Initialize, HL])(f: (HL) ⇒ T): Initialize[T]なので、Initialize[Seq[File]] が返りそう。なんか予想が多いが・・・
(A,B,C) => T最初のタプルの設定の値がそれぞれ渡り、T つまり、Seq[File] を返す関数を渡せばよさそう。

$ cd php-5.3.8 $ find ./ -name "*.h" -or -name "*.c" > cscope.files $ cscope -b -q -kemacs で展開したディレクトリあたりを開いて、 M-x cscope-find-global-definition is_writable を実行。

14 行目で Content-Type の charset からエンコードを取得して、指定があれば、17 行明で明示的に指定してやることに。直接渡しているので、Shift_JIS 等で部分的に文字化けがおきそうだがとりあえず。this(reader,(reader instanceof InputStreamReader) ? ((InputStreamReader)reader).getEncoding() : null);となっていて、instanceof が気に入らない。Source(final Reader reader, final String encoding) が public だといいのだが。

Jericho HTML だけで対処出来る方法があればいいのだが。class ParentClass
{
private:
virtual void func1() { std::cout << "Parent private func1" << std::endl; }
protected:
virtual void func2() { std::cout << "Parent protected func2" << std::endl; }
public:
virtual void func3() { std::cout << "Parent public func3" << std::endl; }
public:
virtual ~ParentClass() {}
virtual void call()
{
func1();
func2();
func3();
}
};
private, protected, public の 3 種類のメソッドと、それらを呼び出すメソッドを作成。class Child1Class : public ParentClass
{
public:
virtual void func1() { std::cout << "Child1 private -> public func1" << std::endl; }
virtual void func2() { std::cout << "Child1 protected -> public func2" << std::endl; }
virtual void func3() { std::cout << "Child1 public func3" << std::endl; }
virtual ~Child1Class() {}
};
シンタックスエラーは起きない。class Child2Class : public ParentClass
{
protected:
virtual void func1() { std::cout << "Child2 private -> protected func1" << std::endl; }
virtual void func2() { std::cout << "Child2 protected func2" << std::endl; }
virtual void func3() { std::cout << "Child2 protected -> protected func3" << std::endl; }
public:
virtual ~Child2Class() {}
};
これもシンタックスエラーは起きない。class Child3Class : public ParentClass
{
private:
virtual void func1() { std::cout << "Child3 private func1" << std::endl; }
virtual void func2() { std::cout << "Child3 protected -> private func2" << std::endl; }
virtual void func3() { std::cout << "Child3 public -> private func3" << std::endl; }
public:
virtual ~Child3Class() {}
};
これもシンタックスエラーは起きない。ParentClass* p = new ParentClass(); p->call(); std::cout << "----------" << std::endl; delete p; Child1Class* c1 = new Child1Class(); c1->call(); std::cout << "----------" << std::endl; delete c1; Child2Class* c2 = new Child2Class(); c2->call(); std::cout << "----------" << std::endl; delete c2; Child3Class* c3 = new Child3Class(); c3->call(); delete c3;結果は、
Parent private func1 Parent protected func2 Parent public func3 ---------- Child1 private -> public func1 Child1 protected -> public func2 Child1 public func3 ---------- Child2 private -> protected func1 Child2 protected func2 Child2 protected -> protected func3 ---------- Child3 private func1 Child3 protected -> private func2 Child3 public -> private func3
