. # gsub(pattern) -> Enumerator (101.0) -
$_.gsub とほぼ同じですが、置換が発生したときは、$_の内容を置き換える点が異なります。 コマンドラインオプションで -p または -n を指定した時のみ定義されます。
$_.gsub とほぼ同じですが、置換が発生したときは、$_の内容を置き換える点が異なります。
コマンドラインオプションで -p または -n を指定した時のみ定義されます。
暗号的になりすぎるきらいがあるため、このメソッドの使用は推奨されていません。
今後はより明示的な $_.gsub を使ってください。
$_.gsub とこのメソッド gsub は以下の点で違いがあります。
* gsub は $_ の値をコピーして、コピーの方を更新し、
$_ に再代入します。
@param pattern 置き換える文字列のパターンを表す文字列か正規表現。

# convertible _ int(type , headers = nil , opts = nil) (65.0) -
Returns the convertible integer type of the given +type+. You may optionally specify additional +headers+ to search in for the +type+. _Convertible_ means actually same type, or typedefed from same type. If the +type+ is a integer type and _convertible_ type is found, following macros are passed as preprocessor constants to the compiler using the +type+ name, in uppercase. * 'TYPEOF_', followed by the +type+ name, followed by '=X' where 'X' is the found _convertible_ type name. * 'TYP2NUM' and 'NUM2TYP, where 'TYP' is the +type+ name in uppercase with replacing '_t' suffix with 'T', followed by '=X' where 'X' is the macro name to convert +type+ to +Integer+ object, and vice versa. For example, if foobar_t is defined as unsigned long, then convertible_int("foobar_t") would return "unsigned long", and define macros: #define TYPEOF_FOOBAR_T unsigned long #define FOOBART2NUM ULONG2NUM #define NUM2FOOBART NUM2ULONG

# check _ signedness(type , headers = nil , opts = nil) -> "signed" | "unsigned" | nil (49.0) -
Returns the signedness of the given +type+. You may optionally specify additional +headers+ to search in for the +type+.

For example, if size_t is defined as unsigned, then check_signedness('size_t') would returned +1 and the SIGNEDNESS_OF_SIZE_T=+1 preprocessor macro would be passed to the compiler, and SIGNEDNESS_OF_INT=-1 if check_signedness('int') is done.
