YAML filter borks Radiant

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:

Shouldn’t that be in lowercase:

require ‘yaml’

?

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.
:slight_smile:
