rich.pretty.install does not work for IPython

[zhengyu-yang]

Version:

Python 3.8.13
IPython 8.12.2

It seems that get_ipython is not in globals when executed in pretty.py, causing the rich text formatter not being installed. It is actually in globals()['__builtins__']. I suggest just use try to replace this check. The problem happens here:

rich/rich/pretty.py

Line 214 in 8c7449f

if "get_ipython" in globals():

The fix is:

  try:
      ip = get_ipython()  # type: ignore[name-defined]
      from IPython.core.formatters import BaseFormatter

      class RichFormatter(BaseFormatter):  # type: ignore[misc]
          pprint: bool = True

          def __call__(self, value: Any) -> Any:
              if self.pprint:
                  return _ipy_display_hook(
                      value,
                      console=get_console(),
                      overflow=overflow,
                      indent_guides=indent_guides,
                      max_length=max_length,
                      max_string=max_string,
                      max_depth=max_depth,
                      expand_all=expand_all,
                  )
              else:
                  return repr(value)

      # replace plain text formatter with rich formatter
      rich_formatter = RichFormatter()
      ip.display_formatter.formatters["text/plain"] = rich_formatter
  except NameError:
      sys.displayhook = display_hook
