Hi,
Does anyone know of smiley parser - that can parse for standard smileys
{ :), :( etc } and replace with images?
I also wanted URL parser that can automagically give hyperlinks to URLs.
Any inputs?
PS:
http://www.rubyonrails.ch/doku.php/wiki:syntax#smileys
This seemed interesting, but didnt really knw how to use it.
Regards,
Sandeep G

Sandeep,
I recently had to do this for an app... spent lots of time searching.
Here, this will save you some time:
reg = /(http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-9]+)*\.[a-z]{2,5}(:
[0-9]{1,5})?(\/[^\s]*)/ix
line.gsub(reg,%q[<a href=''\0''>\0</a>])
Do some console tests with that just to be sure it matches what you
want, but it''s the best regexp I''ve found for URL matching...
i.e. the
most complete. Note, you can grab various parts using \1, \2, etc. \0
just grabs the whole match.
As for the smilies, I have no idea... that would be a much more
complex matching algorithm. It sounds like an ideal candidate for a
plugin... i.e. "acts_as_smiley". :-)

Of course, as Fred mentioned, auto_link as a helper will do all that anyway: http://api.rubyonrails.com/classes/ActionView/Helpers/TextHelper.html#M001058 Hehe. -Dan On Mar 28, 1:34 pm, Frederick Cheung <frederick.che...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> On 28 Mar 2008, at 19:03, Sandeep Gudibanda wrote: > > > > > Hi, > > > Does anyone know of smiley parser - that can parse for standard > > smileys > > { :), :( etc } and replace with images? > > > I also wanted URL parser that can automagically give hyperlinks to > > URLs. > > auto_link ? > > I don''t know of one, but this shouldn''t be hard, just a bunch of gsubs > really. > > Fred > > > Any inputs? > > > PS: > >http://www.rubyonrails.ch/doku.php/wiki:syntax#smileys > > > This seemed interesting, but didnt really knw how to use it. > > > Regards, > > Sandeep G > > -- > > Posted viahttp://www.ruby-forum.com/.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I am not aware of a smiley parser, but it really is just a matter of
downloading the smiley images and putting them into a directory, then
creating some sort of mapping between a text pattern and a smiley image
and then looping through and doing gsubs.
images/
smilies/
happy.png
sad.png
SMILEY_HASH = { ":)" => ''happy'', ":("
=> "sad" }
def smileyize(message)
returning message do
SMILEY_HASH.each_pair do |key, value|
message.gsub!(key, image_path("#{value}.png"))
end
end
end
Air coded, but you get the idea.

Hi, Thank you all for inputs. Is there a more efficient way of doing GSUB, instead of doing gsub on entire text for each smiley? As the list of Smileys grows big, gsub in loop will be a overhead.

Hi Fred,
def smileyize(text)
smileys = {
"8-)" => ''icon_cool.gif'' ,
"8-O" => ''icon_eek.gif'',
"8-o" => ''icon_eek.gif'',
'':-('' => ''icon_sad.gif'',
'':-)'' => ''icon_smile.gif'',
}
text.gsub /("8-o")/ do |match|
image_path(smileys[match])
end
return text
end
I tried something like this, but didnt work. It sends back the same
text.Can you help me on this?
I even tried to simplify things and test with this:
<%= "XX".gsub /("XX")/ do |match| "YY" end%>
This displays XX itself :(

It occurs to me that YAML could be a real boon here. I.e. define your mappings via YAML (or XML but who does that anymore? *grin*). Probably define it as something simple like: mappings: icon_eek.gif: 8-O icon_sad.gif: :-( etc. then read it into a very similar hash table to what you have, maybe reversing the keys if need be. I think it would be cool to have an "acts_as_smiley" plugin. Maybe something where you could do: class Post < ActiveRecord::Base acts_as_smiley :body, :icons => "myicons" # (this would be a subdir of "images" in public) end Then, "underneath the covers", it redefines the body accessor so that it returns the smiley-parsed value of :body. I could even imagine some other hooks like defining additional accessors, like :body_nosmiley or :body_smiley that skips or runs the parser. Just a thought. Anyway, glad you got it working! -Danimal 8-O --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you think of adding more smileys: regexp = Regexp.new("("+ smileys.keys.map{|k| Regexp.escape(k)}.join("|") +")") with the added benefit that you need to add more smileys in just one place. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
