gitweb.cgi で日本語 (Shift_JIS) の文字化け回避
to_utf8 という関数があるのですが、ここを以下のようにすると
日本語が文字化けしなくなるはずです。
Perl は長らく書いてないので正直適当です。
sub to_utf8 {
my $str = shift;
return undef unless defined $str;
my $enc = guess_encoding($str, qw/shiftjis/);
if (ref $enc && $enc->name eq "shiftjis")...

関数の循環的複雑度
次に，関数の簡潔さ／複雑さを測定するにはどのようにしたらよいでしょうか。簡潔に記述された関数は，十分な命名と抽象化がなされていることが多く，読みやすく改修しやすいものになります。関数の簡潔さ／複雑さを測定する指標の一つに，ロジックの循環的複雑度（Cyclomatic Complexity）というものがあります。
まず単一の関数の循環的複雑度（M）は，次の式によって得られます。
M＝E－N＋2P
E：グラフのエッジ（関数内の処理のブロックをつなぐ線）数
N：グラフのノード（関数内の処理のブロック）数
P：連結されたグラフの数
