This feels like a beginner question so apologies to the experts out there reading this. Please skip to the last line of this post for the 'shortened version of this question'.
For my module, I believe there is a high likelihood the user may not copy a required source file to the module 'files' directory before applying the module. In this use case, we cannot version control the source file with the module due to constraints. As such, I would like to present a custom error message that clearly explains to the user what they need to do (e.g. You must download file X from Y and ensure it is copied to Z before doing a puppet run.) I know that without this custom error message puppet will automatically throw an error when we try to first use the file. That said, I don't believe in this particular case the error message will be user friendly enough as it would look something like this: Error: /Stage[main]/Mymodule::Install/File[/tmp/mydestinationfile.txt]: Could not evaluate: Could not retrieve information from environment production source(s) puppet:///modules/mymodule/mysourcefile.txt To an experienced puppet user this makes perfect sense but to a puppet novice they may initially scratch their head wondering where puppet:///modules/mymodule/mysourcefile.txt would be on the file system. I tried a few things but where I came unstuck was on how to assert against a file in the convention puppet:///modules/mymodule/mysourcefile.txt since this is not a native file representation. TL;DR How do I output a custom error message for a failed assertion that a source file exists. In other words, how do I display a nice error message when puppet:///modules/mymodule/mysourcefile.txt does not exist -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
