Hi. I’m new to Radiant, and still stumbling around the code.

I’ve written a filter to interpret pages written in YAML. Radiant won’t  
run it – it seems that it chokes on the ‘require’ statement. Remove  
the statement and it seems to choke on the rest of it. Can anyone  
advise?

require ‘YAML’  
class PublicationsFilter \< TextFilter  
description\_file File.dirname( **FILE** ) + “/…/publications.html”  
def filter(text)  
data = YAML::load(text)  
html = “”  
data.each { |book|  
code = \<\<EOF

 ![]()
### #{book['title']}

#{book['description']}

 EOF html \<\< code } html end end

What is the error message? (Look in your logs.)

Well, nothing useful in the production.log or fastcgi.crash log. But  
running from the command line produced the following:

eggnog% ./dispatch.fcgi

Umm…so it should. :-%

I had never realised the requires were case-sensitive. That’s three  
hours of my life gone for ever, and several more saved. So thank you.

Shouldn’t that be in lowercase:

require ‘yaml’

?
