reviewbot.tools.base.registry¶

Tool registration

These functions are used to register and look up known tool classes.

Functions

register_tool_class(tool_cls)[source]¶

Register a tool class for later lookup.

The tool class must have a tool_id attribute (either directly set, for unit tests, or through load_tool_classes()), and cannot conflict with another tool.

Parameters:

tool_cls (type) – A tool class to register (subclass of reviewbot.tools.base.tool.BaseTool).

Raises:

ValueError – The tool could not be registered, either due to a missing tool_id or due to a conflict with another tool.

unregister_tool_class(tool_id)[source]¶

Unregister a tool class by its ID.

Parameters:

tool_id (type) – The ID of the tool to unregister.

Raises:

KeyError – The tool could not be found.

get_tool_class(tool_id)[source]¶

Return the tool class with a given ID.

Parameters:

tool_id (unicode) – The ID of the tool to return.

Returns:

The tool class, or None if no tool with that ID exists.

Return type:

type

get_tool_classes()[source]¶

Return all registered tool classes.

This will be sorted in alphabetical order, based on the ID.

Returns:

A list of tool classes (subclasses of reviewbot.tools.base.tool.BaseTool).

Return type:

list of type

load_tool_classes()[source]¶

Load tool classes provided by Review Bot and other packages.

This will scan for any Python packages that provide reviewbot.tools entrypoints, loading the tools into the tool registry.

Any existing tools will be cleared out before this begins, and any errors will be logged.
