Look for common options in a chunk of text. Options that we don’t handle are yielded to the
caller.
# File lib/rdoc/markup/preprocess.rb, line 19
def handle(text)
text.gsub!(/^([ \t]*#?[ \t]*):(\w+):([ \t]*)(.+)?\n/) do
next $& if $3.empty? and $4 and $4[0, 1] == ':'
prefix = $1
directive = $2.downcase
param = $4
case directive
when 'include' then
filename = param.split[0]
include_file filename, prefix
else
result = yield directive, param
result = "#{prefix}:#{directive}: #{param}\n" unless result
result
end
end
end
