1. If the --` + pathOptions.ExplicitFileFlag + ` flag is set, then only that file is loaded. The flag may only be set once and no merging takes place.
|
||
|
|
2. If $` + pathOptions.EnvVar + ` environment variable is set, then it is used as a list of paths (normal path delimitting rules for your system). These paths are merged. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list.
|
||
|
|
3. Otherwise, ` + path.Join("${HOME}", pathOptions.GlobalFileSubpath) + ` is used and no merging takes place.`),
