* call-seq:

* Regexp.new(string, [options [, kcode]]) -> regexp
|

|
* Regexp.new(regexp) -> regexp
|

|
* Regexp.compile(string, [options [, kcode]]) -> regexp
|

* Regexp.compile(regexp) -> regexp

* Regexp.new(string, [options]) -> regexp

* Regexp.new(regexp) -> regexp

|
* Regexp.compile(string, [options) -> regexp
|
||
|
* Regexp.compile(regexp) -> regexp
|
||
|
*
|
||
|
* Constructs a new regular expression from +pattern+, which can be either a
|
||
|
* String or a Regexp (in which case that regexp's options are propagated),
|
||
| ... | ... | |
|
* <em>or</em>-ed together. Otherwise, if +options+ is not
|
||
|
* +nil+ or +false+, the regexp will be case insensitive.
|
||
|
*
|
||
|
* When the +kcode+ parameter is `n' or `N' sets the regexp no encoding.
|
||
|
* It means that the regexp is for binary strings.
|
||
|
*
|
||
|
* r1 = Regexp.new('^a-z+:\\s+\w+') #=> /^a-z+:\s+\w+/
|
||
|
* r2 = Regexp.new('cat', true) #=> /cat/i
|
||
|
* r3 = Regexp.new(r2) #=> /cat/i
