Package ru.vyarus.yaml.updater.update

Class EnvSupport

java.lang.Object

ru.vyarus.yaml.updater.update.EnvSupport

public class EnvSupport
extends java.lang.Object

Environment variables could be used to personalize updating yaml file. For example:

 some:
    - prop: #{var}
 

Such syntax allows yaml parser to treat variable as a comment (if it would not be replaced). Also, variables in format ${va} are often used directly in the configuration (to be replaced at runtime with environment variables).

Variable names are case-sensitive. Unknown variables are not replaced. Null values replaced with empty.
