xonsh 0.8.7

on Python PyPI

Added:

• New xonsh syntax pf strings -- combining path strings with f-strings.

  Usage:

  .. code-block:: bash
  gil@bad_cat ~ $ repos = 'github.com'
  gil@bad_cat ~ $ pf"~/{repos}"
  PosixPath('/home/gil/github.com')
  gil@bad_cat ~ $ pf"{$HOME}"
  PosixPath('/home/gil')
  gil@bad_cat ~ $ pf"/home/${'US' + 'ER'}"
  PosixPath('/home/gil')

Fixed:

• Set ls to predict_true in default_threadable_predictors. This prevents ls on OSX
  from being flagged on OSX as unthreadable (incorrectly) because it relies on ncurses.
