func (*Parser) Read ¶

func (o *Parser) Read() (map[string]any, error)

Read intercepts all active system environment variables, filters out keys that do not match the configured application prefix, strips the prefix, and normalizes the hierarchical separators into standard dot-notation format.

Processing features:

• Trims the mandatory application prefix to clean up the configuration map keys.
• Automatically handles boundary separators to avoid leading dots (e.g., converts APP_DB to db).
• Replaces custom layout delimiters with dot notation (e.g., DB_PORT becomes db.port).

Returns a generic string-interface map containing all parsed and matched environment data.

func (*Parser) SetOptions ¶

func (o *Parser) SetOptions(opts xconfig.Options) error

SetOptions executes validation against the incoming criteria. It requires both Prefix and Separator properties to be explicitly defined, establishing a precise lookup filter for environmental keys.
