Hi Forum, I have various trap messages stored as text in my DB and accessable in my view as @trap. (trap.ipadd, trap.desc etc..) I would like to highlight certain key words in red if they exist in the text. I was thinking of trying to use gsub and add <font> tags when displaying in my view. Can anyone think of an easier way to do this? thanks jackster -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I was thinking about the one in ActionView::Helpers::TextHelper. The description is as follows: highlight(text, phrases, highlighter = ''<strong class="highlight">\1</ strong>'') Highlights one or more phrases everywhere in text by inserting it into a highlighter string. The highlighter can be specialized by passing highlighter as a single-quoted string with \1 where the phrase is to be inserted (defaults to ''<strong class="highlight">\1</strong>'') --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

How do I include that Rails application. I tried just putting this in my
view and it does nothing:
highlight(''this is sample text'', ''text'')
How does rail know about it..maybe I should requiring action_view ?

It should be available in your view. I just tried adding this to my
view and it worked as advertised:
<%= highlight("this is sample text", "text") %>
I''m using Rails 2.0.2.

sorry for that...I didn''t even try it with the <%= at the beginning.....it does work for me too now....thanks for the help on this. The only issue I have is that it makes the text strong bold....what I need is to make it highlighted in red or other colors....I don''t see anything in the doco to do that. I installed Text::HTMLHighlighter and all the tests ran successfully but I can''t seem to figure out how to get it to work in my view. There is an .rb file that I''m supposed to call somehow and I can''t figure you how to do it. The directions seem to make me think Text::HTMLHighlighter is made to work with other ruby files and not specifically for Rails...not sure... jackster Aaron Chase wrote:> It should be available in your view.

The default is to highlight using <strong> text, but you can get the effect you want by doing something like: <%= highlight(''this is sample text'', ''text'', ''<span class=''highlight"> \1</span>'') %> and adding this to your CSS file: .highlight {color: red} --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Burning the candle at both ends, I see from the timestamp of your last
message :-)
You''ve helped me alot, Aaron...and thank you for that.
As you have pointed out...defining highlight in my CSS works perfectly.
In fact, I found that as soon as I defined it, the following statement
works:
<%= highlight(''this is simple text'',
''text'') %>
And I didn''t have to add the <span class = "highlight">
part although
that worked as well.
The last question I have is what happens when I want to highlight more
than one word if it appears in my variable?
For instance, I have a variable that contains a date, what I need to be
able to do is highlight Thu when it''s Thursday but always highlight
2008.
This works to always highlight 2008:
<%= highlight(trap.datetime.to_s, ''2008'') %>
I was hoping I could do something like this but it doesn''t work because
it looks for both of them in a string:
<%= highlight(trap.datetime.to_s, ''Thu, 2008'') %>
What I''m actually trying to accomplish here, is to highlight certain
words in my network traps in red. For instance, if I got a trap that
contained the word "BGP", I want that highlighted in red as well as if
the word "Spanning-tree" is contained in the trap. This is why I was
hoping to be able to specify several words to be highlighted if they
exist in my variable.
thanks alot Aaron,
jackster

Aaron....I wanted to run one more thing by you on this subject if you don''t mind? I am using the following command which works nicely to highlight key words in red if they are contained in my network trap: <%= highlight(trap.desc4.to_s,[''DOWN'', ''COLD'', ''BGP'', ''RESTART'', ''SPAN'']) %> Can you think of an easy way to highlight some words in red and others in another color? I have never used a conditional if statement in a view before and don''t even know if that''s possible....if it was, I was thinking something like this might be the a solution: if <%= highlight(trap.desc4.to_s,[''DOWN'', ''COLD'', ''BGP'', ''RESTART'', ''SPAN'']) %> else <%= highlight_blue(trap.desc4.to_s,[''UP'', ''HOT'', ''OSPF'', ''START'', ''LINK'']) %> ...or perhaps you might know of an easier solution which I am overlooking? thanks for all the help jackster jackster the jackle wrote:> I can''t thank you enough for your help on this...I''m up and running on > this now and all is looking good. > > jackster > > > > > Aaron Chase wrote: >>> On Jan 31, 5:37 am, jackster the jackle <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> wrote: >> >>> The last question I have is what happens when I want to highlight more >>> than one word if it appears in my variable? >>> >> >> Specifying an array for the 2nd argument should do the trick: >> >> <%= highlight(trap.datetime.to_s, [''Thu'', ''2008'']) %> >> >> You may have to add spaces to your phrase strings to prevent the >> highlighter from highlighting things you didn''t intend.

Just off the top of my head, you could write your own helper something
like this:
def highlight_with_color(text, phrases, color_spec)
highlight(text, phrases, ''<span
style="color:#{color_spec};">\1</
span>'')
end
and then use it in your view like this:
<%= highlight_with_color("foo bar", ["foo, bar"],
"#abcdef") %>
Disclaimer: I haven''t actually tried this code, but I think something
like this should work. Someone in this group may also have a better
suggestion...

perhaps I either did a poor job explaining or don''t understand your code, Aaron...please excuse. here''s an example: I have an instance variable: @variable = "this is some text" How can I make the word "this" be red and the word "some" be green? If I define highlight in my CSS, I can make it both of them red or both green with this: <%= highlight(@variable,[''this'', ''some'']) %> but can''t see a way to make each a different color. jackster Aaron Chase wrote:> Just off the top of my head, you could write your own helper something > like this: > > def highlight_with_color(text, phrases, color_spec) > highlight(text, phrases, ''<span style="color:#{color_spec};">\1</ > span>'') > end > > and then use it in your view like this: > > <%= highlight_with_color("foo bar", ["foo, bar"], "#abcdef") %> > > Disclaimer: I haven''t actually tried this code, but I think something > like this should work.

I got lucky and figured this one out. The following sets all the words in the array the color of highlight as defined in my CSS, the outer highlight method sets the word "CDP" to the color of my blue.css: <%=highlight(highlight(trap.desc4.to_s, [''LOST'', ''DOWN'', ''COLD'', ''BGP'', ''RESTART'', ''SPAN''])''<span class="blue">CDP</span>'') %> This works nicely....but do I wonder if I have to add another iteration of the highlight method on top of that for every additional word that I want to make blue? jackster jackster the jackle wrote:> perhaps I either did a poor job explaining or don''t understand your > code, Aaron...please excuse. > > here''s an example: > > I have an instance variable: > > @variable = "this is some text" > > How can I make the word "this" be red and the word "some" be green? > > If I define highlight in my CSS, I can make it both of them red or both > green with this: > > <%= highlight(@variable,[''this'', ''some'']) %> > > but can''t see a way to make each a different color. > > jackster > > > > > Aaron Chase wrote: >> Just off the top of my head, you could write your own helper something >> like this: >> >> def highlight_with_color(text, phrases, color_spec) >> highlight(text, phrases, ''<span style="color:#{color_spec};">\1</ >> span>'') >> end >> >> and then use it in your view like this: >> >> <%= highlight_with_color("foo bar", ["foo, bar"], "#abcdef") %> >> >> Disclaimer: I haven''t actually tried this code, but I think something >> like this should work.
