ruby on rails - How can I identify and process all URLs in a text string? -

-

I would like to enumerate all the URLs in a text string, for example: 

  Text = "fasòls http://george.it sdafsda"

found for each URL, I want to apply a function method (...) Am string

I am using a method like this now: 

  msg = "" if i (i = ~ URI :: regexp) in text.split Nil? Msg = = "" + I and msg + = "" + method (i) end and text = msg

this works, but it is slow for long string how do i Can I increase

I think "gsub" is your friend here: 

  Category UrlParser attr_accessor: text, url_counter ,: urls def initial (text) @text = parse (text) end personal def pars (text) @ counter = 0 @urls = [] text.gsub (% R {(\ A | \ S +) (http: // [^ \ s] +)}) do @hamles & lt; & Lt; $ 2 "# {$ 1} # {replace_url ($ 2)}" end-end DRP replace_url (url) @counter + = 1 "[# {@ counter}]" end and processed_rill = urppres.new ("a http: // x .com / url two ") parsed_url.text puts parsed_url.urls

If you really need extra extraction of strings for long periods of time, Create a C extension.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
