Feature or Bugfix
Purpose
As a step towards #13072, this PR introduces a new
CurrentDocument
type to store and manipulate state in the environment for the document currently being read. This is currently stored in atemp_data
dict.We also rename the attribute on
BuildEnvironment
tocurrent_document
fromtemp_data
, keeping the old name as an alias.At present, none of the old names or e.g. the mapping interface to
CurrentDocument
are deprecated, though I expect that in the future this would be done.For downstream extensions that make use of
env.temp_data['...']
, this should be a transparent refactor.xref:
