xonsh 0.8.4

on Python PyPI

Added:

• Added the possibility of arbitrary paths to the help strings in vox activate and
  vox remove; also updated the documentation accordingly.
• New xonsh.aliases.ExecAlias class enables multi-statement aliases.
• New xonsh.ast.isexpression() function will return a boolean of whether
  code is a simple xonsh expression or not.
• Added top-level run-tests.xsh script for safely running the test suite.

Changed:

• String aliases are no longer split with shlex.split(), but instead use
  xonsh.lexer.Lexer.split().

• Update xonsh/prompt/cwd.py _collapsed_pwd to print 2 chars if a directory begins with "."

• test which determines whether a directory is a virtualenv

  previously it used to check the existence of 'pyvenv.cfg'
  now it checks if 'bin/python' is executable

Fixed:

• Fixed issue with and & or being incoreectly tokenized in implicit
  subprocesses. Auto-wrapping of certain subprocesses will now correctly work.
  For example::

  $ echo x-and-y
  x-and-y
  

• Fix EOFError when press control+d

• fix no candidates if no permission files in PATH

• Fixed interpretation of color names with PTK2 and Pygments 2.3.

• Several ResourceWarnings: unclosed file in tests

• AttributeError crash when using --timings flag

• issue #2929
