xonsh 0.3.0

v0.3.0

on Python PyPI

Added:

• and, or, &&, || have been added as subprocess logical operators,
  by popular demand!
• Subprocesses may be negated with not and grouped together with parentheses.
• New framework for writing xonsh extentions, called xontribs.
• Added a new shell type 'none', used to avoid importing readline or
  prompt_toolkit when running scripts or running a single command.
• New: sudo functionality on Windows through an alias
• Automatically enhance colors for readability in the default terminal (cmd.exe)
  on Windows. This functionality can be enabled/disabled with the
  $INTENSIFY_COLORS_ON_WIN environment variable.
• Added Ellipsis lookup to __xonsh_env__ to allow environment variable checks, e.g. 'HOME' in ${...}
• Added an option to update os.environ every time the xonsh environment changes.
  This is disabled by default but can be enabled by setting $UPDATE_OS_ENVIRON to
  True.
• Added Windows 'cmd.exe' as a foreign shell. This gives xonsh the ability to source
  Windows Batch files (.bat and .cmd). Calling source-cmd script.bat or the
  alias source-bat script.bat will call the bat file and changes to the
  environment variables will be reflected in xonsh.
• Added an alias for the conda environment activate/deactivate batch scripts when
  running the Anaconda python distribution on Windows.
• Added a menu entry to launch xonsh when installing xonsh from a conda package
• Added a new which alias that supports both regular which and also searches
  through xonsh aliases. A pure python implementation of which is used. Thanks
  to Trent Mick. https://github.com/trentm/which/
• Added support for prompt toolkit v1.0.0.
• Added $XONSH_CACHE_SCRIPTS and $XONSH_CACHE_EVERYTHING environment
  variables to control caching of scripts and interactive commands. These can
  also be controlled by command line options --no-script-cache and
  --cache-everything when starting xonsh.
• Added a workaround to allow ctrl-c to interrupt reverse incremental search in
  the readline shell

Changed:

• Running scripts through xonsh (or running a single command with -c) no
  longer runs the user's rc file, unless the --login option is specified.
  Also avoids loading aliases and environments from foreign shells, as well as
  loading bash completions.
• rc files are now compiled and cached, to avoid re-parsing when they haven't
  changed. Scripts are also compiled and cached, and there is the option to
  cache interactive commands.
• Left and Right arrows in the prompt_toolkit shell now wrap in multiline
  environments
• Regexpath matching with backticks, now returns an empty list in python mode.
• Pygments added as a dependency for the conda package
• Foreign shells now allow for setting exit-on-error commands before and after
  all other commands via the seterrprevcmd and seterrpostcmd arguments.
  Sensinble defaults are provided for existing shells.
• PLY is no longer a external dependency but is bundled in xonsh/ply. Xonsh can
  therefore run without any external dependencies, although having prompt-toolkit
  recommended.
• Provide better user feedback when running which in a platform that doesn't
  provide it (e.g. Windows).
• The lexer now uses a custom tokenizer that handles regex globs in the proper
  way.

Fixed:

• Fixed bug with loading prompt-toolkit shell < v0.57.
• Fixed bug with prompt-toolkit completion when the cursor is not at the end of
  the line.
• Aliases will now evaluate enviornment variables and other expansions
  at execution time rather than passing through a literal string.
• Fixed environment variables from os.environ not beeing loaded when a running
  a script
• The readline shell will now load the inputrc files.
• Fixed bug that prevented source-alias from working.
• Now able to ^C the xonfig wizard on start up.
• Fixed deadlock on Windows when runing subprocess that generates enough output
  to fill the OS pipe buffer.
• Sourcing foreign shells will now return a non-zero exit code if the
  source operation failed for some reason.
• Fixed PermissionError when running commands in directories without read permissions
• Prevent Windows fixups from overriding environment vars in static config
• Fixed Optional Github project status to reflect added/removed files via git_dirty_working_directory()
• Fixed xonsh.exe launcher on Windows, when Python install directory has a space in it
• Fixed $CDPATH to support ~ and environments variables in its items
