Hiera / HI-637 Allow usage of Hash Keys as Array Issue Type: Improvement Assignee: Unassigned Created: 2023/01/03 3:11 AM Priority: Normal Reporter: Martin Alfke Within YAML it is possible to specify a hash key as an array: cat yaml.yaml  --- hash:   ['key1', 'key2']:     param: 'value' One can use the YAML.load_file method: irb  2.5.8 :001 > require 'yaml'  => true  2.5.8 :002 > data= YAML.load_file('yaml.yaml')  => {"hash"=>{["key1", "key2"]=>{"param"=>"value"}}}  2.5.8 :003 > puts data {"hash"=>{["key1", "key2"]=>{"param"=>"value"}}}  => nil  2.5.8 :004 > exit Within Hiera YAML Data, the usage of an array as Hash Key title is not possible: Running Puppet lookup explain: Searching for "hash"   Global Data Provider (hiera configuration version 5)     Using configuration "/etc/puppetlabs/puppet/hiera.yaml"     Hierarchy entry "Classifier Configuration Data"       No such key: "hash"   Environment Data Provider (hiera configuration version 5)     Using configuration "/etc/puppetlabs/code/environments/production/hiera.yaml"     Hierarchy entry "yaml hierarchy"       Path "/etc/puppetlabs/code/environments/production/data/nodes/puppet5.yaml"         Original path: "nodes/%{facts.networking.hostname}.yaml"         No such key: "hash"       Path "/etc/puppetlabs/code/environments/production/data/role/-.yaml"         Original path: "role/%{facts.external_facts.role}-%{facts.external_facts.env}.yaml"         Path not found       Path "/etc/puppetlabs/code/environments/production/data/role/.yaml"         Original path: "role/%{facts.external_facts.role}.yaml"         Path not found       Path "/etc/puppetlabs/code/environments/production/data/role/.yaml"         Original path: "role/%{trusted.extensions.pp_role}.yaml"         Path not found       Path "/etc/puppetlabs/code/environments/production/data/os/RedHat.yaml"         Original path: "os/%{facts.os.family}.yaml"         Path not found       Path "/etc/puppetlabs/code/environments/production/data/zone/.yaml"         Original path: "zone/%{facts.external_facts.zone}.yaml"         Path not found       Path "/etc/puppetlabs/code/environments/production/data/common.yaml"         Original path: "common.yaml"         Found key: "hash" value: nil When adding also a string key only the string key gets returned: hash:   'ele1':     param: 'value'   ['key1', 'key2']:     'param': 'value'  Return value:         Found key: "hash" value: {           "ele1" => {             "param" => "value"           } Especially in combination with stdlib::manage::create:resources an Array as Hash Key makes sense: stdlib::manage::create_resources: package: ['less', 'vim', 'htop']: ensure: present But that is not (yet) possible.
