xonsh 0.7.4

on Python PyPI

Added:

• New xonsh-cat command line utility, which is a xonsh replacement
  for the standard UNIX cat command.
• The new xonsh.xoreutils.cat.cat_main() enables the xonsh.xoreutils.cat
  module to be run as a command line utility.
• New CommandsCache.is_only_functional_alias() and
  CommandsCache.lazy_is_only_functional_alias() methods for determining if
  if a command name is only implemented as a function, and thus has no
  underlying binary command to execute.
• xonsh.xontribs.xontribs_load() is a new first-class API for loading
  xontribs via a Python function.
• $COMPLETIONS_DISPLAY now supports readline-like behavior on
  prompt-toolkit v2.

Changed:

• The xonsh Jupyter kernel now will properly redirect the output of commands
  such as git log, man, less and other paged commands to the client.
  This is done by setting $PAGER = 'cat'. If cat is not available
  on the system, xonsh-cat is used instead.
• The setup() function for starting up a working xonsh has aliases,
  xontribs, and threadable_predictors as new additional keyword
  arguments for customizing the loading of xonsh.

Fixed:

• Fixed a bug with converting new PTK2 colors names to old names when using PTK1 or Jupyter
  as the shell type.

• CommandsCache.locate_binary() will now properly return None when
  ignore_alias=False and the command is only a functional alias,
  such as with cd. Previously, it would return the name of the
  command.
• Fixed issue with $COMPLETIONS_DISPLAY raising an error on
  prompt-toolkit v2 when the value was not set to multi.
• ValueError when executing vox list
