Title: Message Title Josh Cooper commented on FACT-3000 Re: Dot notation implemented in Facter 4 is incomplete The facter 3 code for looking up a fact value is in https://github.com/puppetlabs/facter/blob/6d7ffc6efdfbc3b1fc79311cdeb4581ac2098d9c/lib/src/facts/collection.cc#L466-L510.

Facter / FACT-3000
Dot notation implemented in Facter 4 is incomplete
Change By:
Nick Walker
Primary problem: - There is no way to override, block, or cache facts that contain a dot in the name or sub-key Facter 4 introduced compositive fact structuring via dot-notation as a feature. However, the dot-notation implementation used is incomplete, and behaves differently from dot-notation elsewhere in the ecosystem.Specifically, Facter 4 dot-notation splits key segments incorrectly, because it does not recognize the use of double or single quotes to indicate keys which contain literal dot characters.The reference implementation for dot-notation is found in Puppet, [here|https://github.com/puppetlabs/puppet/blob/85bd9ed07e3e6c956f1972624a50be914292e1ab/lib/puppet/pops/lookup/sub_lookup.rb#L6-L44].Full dot-notation should be supported everywhere Facter 4 currently evaluates dot-notation strings to segment structured fact names. This includes external fact output (text, json, yaml), as well as {{Facter.add()}}.*Today's behavior*Consider the following plain-text custom fact file:{code}foo.bar._one_=1foo.bar.two=2foo."i.have.dots"=3"me.too"=4{code}Today, Facter 4 returns the following for these facts.{code:json}{ "foo": {"bar": { "one": "1", "two": "2"},"\"i": { "have": {"dots\"": "3" }} }, "\"me": {"too\"": "4" }}{code}This is incorrect.*Correct behavior*Full and correct support for dot-notation SHOULD give:{code:json}{ "foo": {"bar": { "one": "1", "two": "2"},"i.have.dots": "3" }, "me.too": "4"}{code}

Title: Message Title Josh Cooper commented on FACT-3000 Re: Dot notation implemented in Facter 4 is incomplete I'm on completing dot notation handling in Facter 4. Also we have many cases in the puppet ecosystem where dots are special and must be escaped if you want a literal dot. For example, https://puppet.com/docs/puppet/7.5/hiera_automatic.html#hiera_dotted_notation. So the behavior described here would provide more consistency.
