This is a prototype project with a few goals:

• Replace existing Drush sitealias code with class-based implementation.
• Load aliases from .yml files instead of .drushrc.php files.
• Load and convert legacy .drushrc.php files.
• Provide a reusable library for other systems that might wish to interact with Drush alias files.
• Simplify alias implementation and reduce recursive searching, etc. in order to improve performance, as possible.

The classes do not contain any logic to determine where aliases should be loaded from. These must be supplied by the caller.

See the examples directory for example alias files.

\Drush\Context\Context:

A key/value store.

\Drush\Context\ContextList:

A prioritized list of contexts. Also provides accessor functions that will return a matching value from the first context that contains it.

\Drush\Context\Alias:

A \Drush\Context\Context that also contains specific methods particular to aliases.
