xonsh 0.8.11

on Python PyPI

Added:

• New xonsh.color_tools.short_to_ints() function for directly
  converting a short (0 - 256) color into a 3-tuple of ints
  represeting its RGB value.
• New xonsh.ansi_colors.ansi_reverse_style() function for
  converting a mapping of color names to ANSI escape codes into
  a mapping from escape codes into color names. This is not a
  round-trippable operation.
• New xonsh.ansi_colors.ansi_color_escape_code_to_name() function
  for converting an ANSI color escape code into the closest xonsh
  color name for a given style.
• New xonsh.events.EventManager.exists() method enables the checking
  of whether events actually exist with out making the event if it
  doesn't exist.
• New command-specific event categories called on_pre_spec_run_<cmd-name>
  and on_post_spec_run_<cmd-name> will be fired before and after
  SubpocSpec.run() is called. This allows for command specific
  events to be executed. For example, on_pre_spec_run_ls would
  be run prior to an invocation of ls.
• New xonsh.environ.LsColors class for managing the $LS_COLORS
  environment variable. This ensures that the ls command respects the
  $XONSH_COLOR_STYLE setting. An instance of this class is added to the
  environment when either the $LS_COLORS class is first accessed or
  the ls command is executed.
• The on_pre_spec_run_ls event is initialized with a default handler
  that ensures that $LS_COLORS is set in the actual environment prior
  to running an ls command.
• New xonsh.tools.detype() function that simply calls an objects own
  detype() method in order to detype it.
• New xonsh.tools.always_none() function that simply returns None.
• New Env.set_ensurer() method for setting an ensurer on an environment.

Changed:

• The black and white style bw now uses actual black and white
  ANSI colore codes for its colors, rather than just empty color
  sequences.

• An environment variable detype operation no longer needs to be
  function, but may also be None. If None, this variable is
  considered not detypeable, and will not be exported to subprocess
  environments via the Env.detype() function.

• An environment variable detype function no longer needs to return
  a string, but may also return None. If None is returned, this
  variable is considered not detypeable, and will not be exported to
  subprocess environments via the Env.detype() function.

• The Env.detype() method has been updated to respect the new
  None types when detyping.

• The xonsh.tools.expandvars() function has been updated to respect
  the new None types when detyping.

• The xonsh.xonfig.make_xonfig_wizard() function has been updated to respect
  the new None types when detyping.

• Event handlers may now be added and discarded during event firing for
  normal events. Such modifications will not be applied to until the
  current firing operation is concluded. Thus you won't see newly added
  events fired.

• xonsh now uses its own vended version of ply. Any installed versions will no longer be used. This reflects that ply is no
  longer distributed as an installable packages.

• Updated to used ply version 3.11.

• Reverted change in give_to_terminal to restore working version of
  cmake, rm -i, etc. This breaks pv | head.

Deprecated:

• The xonsh.color_tools.make_pallete() function is no
  longer deprecated, as it is actually needed in other parts of
  xonsh still, such as pyghooks.

Removed:

• All code references to $FORMATTER_DICT have been removed.

Fixed:

• Resolved issues where macro functions were not able to properly
  accept single-line statements in exec and single mode.

• Minor fixes to xonsh.events.debug_level().

• Fixed a regression where some interactive commands were not waited for
  properly for long enough.

• Fixed environments not showing in the prompt when using Anaconda Python.

• Fixed regression with anaconda activate/deactivate scripts not wokring on Windows.
