Template Context Processors Extension Point


The extension point abbreviation is tcp.

Its role is to automatically introduce variables or functions you define into the template environment for use in templates (like g, request, url_for).

The plugin needs to return the tcp field via register. The data type required for this field is dict, and the format is {var_name=var, func_name=func}.

The Flask-PluginKit loads tcp via _context_processor_handler(), this method will detect tcp rules and specific content.
