What’s the possibility of having a markaby filter, or markaby in the
layouts?
Caylan
What an excellent idea! I’ve yet to hack around with the filters, but
now I
definitely want to. Anyone have any thoughts on how easy / ridiculous
this
would be to implement?
The only problem I can see is that as pretty as Markaby is in pure Ruby,
the
Radius tags sort of ruin the effect with their <> nonsense

p.date { span.highlight date.format("%b %d, %Y") }
h5 r.link
end
end
end
end
Rough and full of typos, logic errors, and cyanide.

Okay, I just looked into the code & I still see a problem here. . .
unfortunately. Radiant’s filters run after any <r: /> tags have been
processed, and Radiant uses the Radius system to do all its custom tags.
As
I see it, you’d have to rewrite quite a bit of Radius to make this work
like
you’ve written it. I don’t see any other way to turn things like <r:find
/>
into r.find.
Disclaimer: I could be completely wrong about this

the layouts).
Not to be naive, but where are these defined? I’m using locomotive.
Is there an easy ruby way to figure that out? For instance…
starting IRB and loading the class, then asking it where it’s defined?

Whenever I’m stumped about where a method definition is, I just do a
search for “def method_name.” If you happen to use TextMate, you can
easily do a project-wide search with command-shift-f and you usually
have the answer in a few short seconds. Otherwise, you could just
keep a terminal window open in the root of your radiant app for using
grep, or something similar.

Behavior::Base is defined in app/models/behavior.rb:
http://dev.radiantcms.org/radiant/browser/trunk/radiant/app/models/behavior.rb

No. Ruby doesn’t makes it easy for you to get at that information.

I’ve been experimenting around today trying to get markaby working as
a filter. I’ve run into a number of problems though so I’m putting it
out to the mailing list to see if someone can improve it.
Firstly it seems Ruby syntax can only handle simple radius tags
without parameters. So a simple tag like
h2{r:date}
works but a tag like
r:link(:url=>“http://localhost/”)
does not, although
r:link do
test(“link”)
end
does work. Also it doesn’t seem to like the {} block delimeters so
r:random {
r:option {text(“random1”)}
r:oprion {text(“random2”)}
}
won’t parse but
r:random do
r:option do;text(“random1”);end
r:option do;text(“random2”);end
end
works.
Anyway here’s the code for the filter I was using. I had to redefine
parse_object and change the order of filtering and parsing by radius,
hopefully that doesn’t cause problems with other filters.
require ‘markaby’
class Behavior::Base
def parse_object(object)
text = object.content
text = object.filter.filter(text) if object.respond_to? :filter_id
text = parse(text)
text
end
end
class MarkabyFilter < TextFilter::Base
register ‘Markaby’
def filter(text)
Markaby::Template.new(text).render+
end
end

Have you guys considered Jim W.'s Builder? Although a bit more
wordy than Markaby in terms of code, it allows curly braces and you can
output unescaped text (i.e. Radius tags, if necessary) using the <<
operator. Unlike Markaby, however, it would have to be eval’d in the
filter method. Here’s an example of how you might do it.
require ‘builder’
class BuilderFilter < TextFilter::Base
register ‘Builder::XmlMarkup’
def filter(text)
x = Builder::XmlMarkup.new :indent => 2
eval(text)
x.target!
end
end
Documentation for this filter would obviously have to include what the
local variable name is for the XmlMarkup object since Builder 2.0
requires a target for all of its markup calls.
