Martin Panter added the comment:
I moved all the calls targetting the readline module into a ReadlineCompleter
subclass. However the logic for parsing “import” statements still exists in the
base Completer class in private methods. An overview of the two classes:
class Completer:
def complete(self, text, state):
self._get_matches(text)
def _get_matches(text):
# Only completes global and object.attr names, like before
def _code_matches(self, code, ...):
# Completes import statements, otherwise returns (None, ...)
class ReadlineCompleter(Completer): # New public class
def complete(self, text, state):
# Moved Yury’s Tab insertion logic here
return super().complete(...)
def _get_matches(text):
code = readline.get_line_buffer()[:readline.get_endidx()]
self._code_matches(code)
super()._get_matches(text) # Fallback to existing behaviour
Perhaps the _code_matches() and related methods could be turned into more
general public APIs, e.g. complete_code(code) -> list of modules, attributes,
globals, etc. But that would affect global_matches() and attr_matches(), which
I have not touched so far.
Other changes:
* Limit underscore-prefixed completions, consistent with Issue 25011; see new
_filter_identifiers() method
* Changed the demo in the documentation; attributes like __doc__ are omitted by
default
* Removed workaround for non-ASCII input in favour of fixing Issue 16182
