Did you know that the ๐ก๐ผ๐ฑ๐ฒ๐ท๐ ๐๐๐ถ๐น module lets you deprecate functions and classes?
The ๐๐๐ถ๐น.๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ฒ method wraps your function/class in a way that makes it deprecated. When your function/class gets called, a ๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป๐ช๐ฎ๐ฟ๐ป๐ถ๐ป๐ด will be emitted using the ๐๐ฎ๐ฟ๐ป๐ถ๐ป๐ด event. The emitted event will be outputted to ๐๐๐ฑ๐ฒ๐ฟ๐ฟ the very first time the function gets called. After that, any later calls won't log the warning.
Related options and flags:
If either the --๐ป๐ผ-๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป or --๐ป๐ผ-๐๐ฎ๐ฟ๐ป๐ถ๐ป๐ด๐ command-line flags are used, or if the ๐ฝ๐ฟ๐ผ๐ฐ๐ฒ๐๐.๐ป๐ผ๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป property is set to true prior to the first deprecation warning, the ๐๐๐ถ๐น.๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ฒ method does nothing.
If the --๐๐ฟ๐ฎ๐ฐ๐ฒ-๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป or --๐๐ฟ๐ฎ๐ฐ๐ฒ-๐๐ฎ๐ฟ๐ป๐ถ๐ป๐ด๐ command-line flags are set, or the ๐ฝ๐ฟ๐ผ๐ฐ๐ฒ๐๐.๐๐ฟ๐ฎ๐ฐ๐ฒ๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป property is set to true, a warning and a stack trace are printed to ๐๐๐ฑ๐ฒ๐ฟ๐ฟ the first time the deprecated function is called.
If the --๐๐ต๐ฟ๐ผ๐-๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป command-line flag is set, or the ๐ฝ๐ฟ๐ผ๐ฐ๐ฒ๐๐.๐๐ต๐ฟ๐ผ๐๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป property is set to true, then an exception will be thrown when the deprecated function is called.
The --๐๐ต๐ฟ๐ผ๐-๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป command-line flag and ๐ฝ๐ฟ๐ผ๐ฐ๐ฒ๐๐.๐๐ต๐ฟ๐ผ๐๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป property take precedence over --๐๐ฟ๐ฎ๐ฐ๐ฒ-๐ฑ๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป and ๐ฝ๐ฟ๐ผ๐ฐ๐ฒ๐๐.๐๐ฟ๐ฎ๐ฐ๐ฒ๐๐ฒ๐ฝ๐ฟ๐ฒ๐ฐ๐ฎ๐๐ถ๐ผ๐ป.
