hi! I''ve seen it reported that there is no official doc for parsedfile; does anyone know if this is still true? I''m trying to make a new type and getting stuck on how parsedfile works . . . Any help would be appreciated: regarding the "Puppet::Type.type(:newType).provide" line: 1. What does the ":parsed" label do? Are there other options? 2. Are there other types of ":filetypes" besides ":flat"? Does labeling as :flat have any affect on the parsing? regarding "record_line": 1. can the "name" parameter be anything? is ":parsed" anything special? Is the name used for anything? 2. what exactly do the parenthetic groupings do, e.g. /^\s+(.*)=(.*):$/ ? 3. Is there a relationship between the parenthetic groupings and the ":fields" label? 4. what is the relationship between :fields in provider, "newparams" in type & fields in manifest/init.pp? 4a. Why do i get the following error when I don''t have stuff_1 as ":optional": Could not evaluate: Field ''stuff_1'' is required 5. What does :post_parse do? 6 What does :pre_gen do? 7 Are there any other "mystery" parameter? Thanks soooooooo much!!

I don''t think it really matters, except that there can''t be two provider of the same name for a given puppet type.> 2. Are there other types of ":filetypes" besides ":flat"?

I think the name is used if you ever want to look up for a given record_line.> 2. what exactly do the parenthetic groupings do, e.g. /^\s+(.*)=(.*):$/ ?It''s a regex capture.> 3.

I think the first capture will end up in the first ''field'' and so on for the subsequent capture/field.> 4. what is the relationship between :fields in provider, "newparams" in > type & fields in manifest/init.pp?The role of a given provider is to fill in resource properties and later on, commit updated properties to the target "physical" resource. So, yes you need a field per newproperty in the type.> 4a. Why do i get the following error when I don''t have stuff_1 as > ":optional": Could not evaluate: Field ''stuff_1'' is requiredWe need to see the code to help with specific errors.> 5. What does :post_parse do?It allows to run some specific code after the parsing of a given record line happens. It allows to modify was what read, or munge some values...> 6 What does :pre_gen do?It allows to run provider specific code before the to_line operation happens.> 7 Are there any other "mystery" parameter?There''s at least process, if you want to use your own parsing instead of relying on the regex. And there is a bunch of options to modify how the parsing happens. Check for more information: Puppet::Util::FileParsing and Puppet::Provider::ParsedFile Hope that will help you :) -- Brice Figureau My Blog: http://www.masterzen.fr/ -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Thanks for the reply!! One more thing I can''t quite figure out: How
to get
a new entry in my target file! I can parse, but an entry in manifests
doesn''t magically appear. Do I need to add something to my provider or
type
to get that to happen? Any help would be soooo appreciated; i''m
getting
tired of struggling with this!
vncserver/manifests/init.pp
class vncserver {
vncserver { ''guymatz'':
port => ''92'',
geometry => ''1024x768'',
ensure => ''present''
}
} # class vncserver
vncserver/lib/puppet/type/vncserver.rb
require ''puppet/property/list''
require ''puppet/provider/parsedfile''
Puppet::Type.newtype(:vncserver) do
ensurable
newparam(:port) do
desc "The vnc servers port assignment. Will be +5900 on the
server"
end
newparam(:name) do
isnamevar
desc "The user who will own the VNC session."
end
newparam(:geometry) do
desc "Resolution for VNC, in XxY, e.g. 1024x768."
end
newparam(:password) do
desc "Password to be put into users .vnc/passwd."
end
newparam(:args) do
desc "Optional arguments to be added to the vncserver
command-line."
end
@doc = "Installs and manages entries for vncservers. For Redhat-bases
systems, and likely many others, these entries will be in
/etc/sysconfig/vncservers."
end
and, finally, my very unfinished provider:
vncserver/lib/puppet/provider/vncserver/parsed.rb:
require ''puppet/provider/parsedfile''
vncservers = "/etc/sysconfig/vncservers"
Puppet::Type.type(:vncserver).provide(:parsed,
:parent =>
Puppet::Provider::ParsedFile,
:default_target => vncservers,
:filetype => :flat
) do
desc "The vncserver provider that uses the ParsedFile class"
confine :exists => vncservers
text_line :comment, :match => /^\s*#/;
text_line :blank, :match => /^\s*$/;
record_line :parsed,
:joiner => '''',
:fields => %w{port geometry optional_args},
:optional => %w{port geometry },
:match => /^VNCSERVERARGS\[(\d+)\]="-geometry
(\d+x\d+)(.*)$/,
:to_line => proc { |record|
"VNCSERVERARGS[#{record[:port]}]=\"-geometry
#{record[:geometry]} #{record[:optional_args]}\""
}
record_line :parsed_again,
:joiner => '''',
:fields => %w{port_name},
:optional => %w{port_name},
:match => /^VNCSERVERS="(.*)"$/,
:to_line => proc { |record|
"VNCSERVERS=\"#{record[:port_name]}\""
}
end

Unfortunately, the parsedfile provider is mainly documented by code that uses it. I''ve been meaning to write up a document on it, but I''ve been unable to find the time. In the mean time, the OSUOSL has some providers for gentoo that use the parsedfile provider, found at https://github.com/ramereth/puppet-gentoo/blob/master/lib/puppet/provider/package_use/parsed.rb that may give you a bit more insight. Sorry for the non-answer here, but this might get you a bit further along. On Thu, Oct 13, 2011 at 2:47 PM, Guy Matz <gmatz@matz.org> wrote:> Thanks for the reply!!

Thanks! That begs the question: What''s the difference between newparam & newproperty? One other thing: Does anyone know why I would get the following error after switching from newparam to newproperty? err: Could not retrieve catalog from remote server: Could not intern from pson: undefined method `merge'' for []:Array Thanks again, Guy On Fri, Oct 14, 2011 at 4:31 AM, Brice Figureau < brice-puppet@daysofwonder.com> wrote:> Hi, > > On Thu, 2011-10-13 at 17:47 -0400, Guy Matz wrote: > > Thanks for the reply!!
