Description

Deprecation warnings are managed with the Git.deprecation attribute.

Use this object to define deprecations in the source code:

Git.deprecation.deprecate_methods(Git::Branch, stashes: 'use Git::Base#stash_list instead')

The default action when using deprecated items (methods, classes, etc.) is to output
a DEPRECATION WARNING to $stderr like the following:

DEPRECATION WARNING: stashes is deprecated and will be removed from git 2.0.0 (use Git::Base.stash_list instead)

The action taken when a deprecated item is used is defined by setting the behavior
on the deprecation object:

# Log all deprecation warnings to $stderr (the default)
Git.deprecation = :stderr

# Raise an ActiveSupport::DeprecationException
Git.deprecation = :raise

# Do nothing
Git.deprecation = :silence

See ActiveSupport::Deprecation for more details on how to use deprecations.
