@section Deprecation

|
From time to time functions and other features of Guile become obsolete.
|
|
Guile's @dfn{deprecation} is a mechanism that can help you cope with
|
|
this.
|
|
|
|
When you use a feature that is deprecated, you will likely get a warning
|
|
message at run-time. Also, if you have a new enough toolchain, using a
|
|
deprecated function from @code{libguile} will cause a link-time warning.
|
|
|
|
The primary source for information about just what interfaces are
|
|
deprecated in a given release is the file @file{NEWS}. That file also
|
|
documents what you should use instead of the obsoleted things.
|
|
|
|
The file @file{README} contains instructions on how to control the
|
|
inclusion or removal of the deprecated features from the public API of
|
|
Guile, and how to control the deprecation warning messages.
|
|
|
|
The idea behind this mechanism is that normally all deprecated
|
|
interfaces are available, but you get feedback when compiling and
|
|
running code that uses them, so that you can migrate to the newer APIs
|
|
at your leisure.
