Title: Message Title
Henrik Lindberg updated an issue
Puppet / PUP-7531
give user control over optional/strict in hiera interpolation
Change By:
Henrik Lindberg
PUP-7530 deals with the uniqueness of input in a hiera.yaml. That issues is a problem in general, but was detected for the special case of {{undef}} in the input.Currently the user has no way to declare that interpolated values must exist. If {{\--strict_variables}} is turned on an operation will fail when referencing a non existing variable, but there is nothing indicating if a value is missing in a navigation (unless trying to navigate passed an {{undef}}).The following could be a solution:* if an interpolation is followed by {{=}}, the remainder up to the closing of the interpolation is taken as the default value to use for that interpolation if the left of the {{=}} resulted in {{undef}}, either because variable is not set, or if navigation into value produces {{undef}}.* if an interpolation is followed by {{!}}, the reference is taken as a strict reference. ** In a hiera.yaml interpolation this is taken as a disqualification of the input (the path is skipped). This is of value as it saves the user from inventing paths to files like 'nothing' (with the risk of someone putting something in that file), or using a directory path as a path to 'nothing' (which is harder to understand). When skipped explain contains this information. No warning is issued as user asked for this processing to take place.** In interpolation of a data value, this would result in explain output and a warning * It is not possible to combine {{=}} and {{!}}
