xonsh 0.8.0

on Python PyPI

Added:

• Windows CI jobs on Azure Pipelines

• The cryptop command will no longer have its output captured
  by default.

• Added new env-var PTK_STYLE_OVERRIDES. The variable is
  a dictionary containing custom prompt_toolkit style definitions.
  For instance::

  $PTK_STYLE_OVERRIDES['completion-menu'] = 'bg:#333333 #EEEEEE'

  will provide for more visually pleasing completion menu style whereas::

  $PTK_STYLE_OVERRIDES['bottom-toolbar'] = 'noreverse'

  will prevent prompt_toolkit from inverting the bottom toolbar colors
  (useful for powerline extension users)

  Note: This only works with prompt_toolkit 2 prompter.

Changed:

• All __xonsh_*__ builtins have been migrated to a XonshSession instance at
  __xonsh__. E.g. __xonsh_env__ is now __xonsh__.env.
• Other xonsh-specific builtins (such as XonshError) have been proxied to
  the __xonsh__ session object as well.

Deprecated:

• All __xonsh_*__ builtins are deprected. Instead, the corresponding
  __xonsh__.* accessor should be used. The existing __xonsh_*__ accessors
  still work, but issue annoying warnings.

Fixed:

• Fixed deprecation warnings from unallowed escape sequences as well as importing abstract base classes directly from collections

• Fix for string index error in stripped prefix

• bash_completions to include special characters in lprefix

  Previously, glob expansion characters would not be included in lprefix for replacement

  .. code-block:: sh

  $ touch /tmp/abc
  $ python

  from bash_completion import bash_completions

  def get_completions(line):
  ... split = line.split()
  ... if len(split) > 1 and not line.endswith(' '):
  ... prefix = split[-1]
  ... begidx = len(line.rsplit(prefix)[0])
  ... else:
  ... prefix = ''
  ... begidx = len(line)
  ... endidx = len(line)
  ... return bash_completions(prefix, line, begidx, endidx)
  ...
  get_completions('ls /tmp/a*')
  ({'/tmp/abc '}, 0)

  Now, lprefix begins at the first special character:

  .. code-block:: sh

  $ python

  from bash_completion import bash_completions

  def get_completions(line):
  ... split = line.split()
  ... if len(split) > 1 and not line.endswith(' '):
  ... prefix = split[-1]
  ... begidx = len(line.rsplit(prefix)[0])
  ... else:
  ... prefix = ''
  ... begidx = len(line)
  ... endidx = len(line)
  ... return bash_completions(prefix, line, begidx, endidx)
  ...
  get_completions('ls /tmp/a*')
  ({'/tmp/abc '}, 7)

• The xonsh.main.setup() function now correctly passes the
  shell_type argument to the shell instance.

• try_subproc_toks now works for subprocs with trailing and leading whitespace

  Previously, non-greedy wrapping of commands would fail if they had leading and trailing whitespace:

  .. code-block:: sh

  $ true && false || echo a
  xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
  NameError: name 'false' is not defined

  $ echo; echo && echo a

  xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
  NameError: name 'echo' is not defined

  Now, the commands are parsed as expected:

  .. code-block:: sh

  $ true && false || echo a
  a

  $ echo; echo && echo a

  a
