我们从Python开源项目中，提取了以下7个代码示例，用于说明如何使用docutils.nodes.substitution_reference()。
def substitution_reference(self, match, lineno): before, inlines, remaining, sysmessages, endstring = self.inline_obj( match, lineno, self.patterns.substitution_ref, nodes.substitution_reference) if len(inlines) == 1: subref_node = inlines[0] if isinstance(subref_node, nodes.substitution_reference): subref_text = subref_node.astext() self.document.note_substitution_ref(subref_node, subref_text) if endstring[-1:] == '_': reference_node = nodes.reference( '|%s%s' % (subref_text, endstring), '') if endstring[-2:] == '__': reference_node['anonymous'] = 1 else: reference_node['refname'] = normalize_name(subref_text) self.document.note_refname(reference_node) reference_node += subref_node inlines = [reference_node] return before, inlines, remaining, sysmessages
def apply(self): config = self.document.settings.env.config # only handle those not otherwise defined in the document to_handle = default_substitutions - set(self.document.substitution_defs) for ref in self.document.traverse(nodes.substitution_reference): refname = ref['refname'] if refname in to_handle: text = config[refname] if refname == 'today' and not text: # special handling: can also specify a strftime format text = ustrftime(config.today_fmt or _('%B %d, %Y')) ref.replace_self(nodes.Text(text, text))
