yae - YAML aliases expander

yae is a YAML aliases expander, written by Go.

Motivation

When refactoring a long YAML using anchor/alias, I created it to make sure that the original YAML and the refactored YAML are identical.

By comparing the original YAML with the refactored YAML output from the yae command with diff, you can verify that the contents of YAML have not changed.

$ diff <(yae original.yaml) <(yae refactored.yaml)

Since the yae command can change the indentation of the list, the sequence of keys, and other parts that are not relevant to the meaning of YAML, the original YAML uses this command to ensure that the diff command does not cause differences in formatting.

Usage

Run the yae command with the YAML file path that you want to expand alias as an argument.
