Re: [Puppet Users] parsedfile help needed
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

But you defined them as parameters.
Use newproperty instead of newparam.

Also, you don't have any property in the type for port_name.

Re: [Puppet Users] parsedfile help needed
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.

Re: [Puppet Users] parsedfile help needed
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 s 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+)(.*)$/,

}

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.

[Puppet Users] parsedfile help needed
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 s much!!
