Yes, that's what I recommend.
You might be able to stub out the FileParsing portions of ParsedFile -
that is, the bits that give you 'record_line' and 'text_line', and
just leave the reading/writing bits.
However, you're likely better off starting from scratch.

Hello,
What are you trying to accomplish that led you down this path?
I am trying to make a simple text line type that will work like:
http://projects.puppetlabs.com/projects/puppet/wiki/Simple_Text_Patterns
But without using external programs.
Also I wanted to add the ability to to search the line by regex.
I thought that using ParsedFile this would be easier, but seems that I
will have to write it using simple puppet type and provider.
Thank you.

Hello,
Trying to make a custom type
Type:
module Puppet
newtype(:simple_line) do

newparam(:name) do

end
newproperty(:target) do
defaultto {
if
@resource.class.defaultprovider.ancestors.include?
Puppet::Provider::ParsedFile
@resource.class.defaultprovider.default_target
else
nil
end

end
newproperty(:pcre_pattern) do

if value.class != String
raise ArgumentError, "Shoult be string"
else
super
end
end
end
newproperty(:line) do
validate do |value|
if value.is_a? String
raise ArgumentError, "Shoult be string"
else
super
end
end
end
end
end
Provider:
require 'puppet/provider/parsedfile'
target = "/tmp/simple_line_dummy_file"
Puppet::Type.type(:simple_line).provide(
:parsed,
:parent => Puppet::Provider::ParsedFile,
:default_target => target,
:filetype => :flat
) do
text_line :comment,
:match => @resource.value(:pcre_pattern)
Here's your problem - @resource is being evaluated in the provider
class, where it resolves to nil.
There isn't really any good way to have ParsedFile dynamically split
files based on a value passed into a resource - the regex in that
case
is resource-specific, but the file covers many resources.
What are you trying to accomplish that led you down this path?
text_line :blank,
:match => /^\s*$/
record_line :parsed,
:fields => %w{line}
end
But I keep getting this error: NoMethodError: undefined method
`value'
for nil:NilClass
How can i fix this ?
