.. current developments
v0.4.6
====================
**Added:**
* New option ``COMPLETIONS_CONFIRM``. When set, ``<Enter>`` is used to confirm
completion instead of running command while completion menu is displayed.
* NetBSD is now supported.
* Macro function calls are now available. These use a Rust-like
``f!(arg)`` syntax.
* Macro subprocess call now avalaible with the ``echo! x y z``
syntax.
* A new `event subsystem <http://xon.sh/tutorial_events.html>`_ has been added.
* howto install sections for Debian/Ubuntu and Fedora.
* ``History`` methods ``__iter__`` and ``__getitem__``
* ``tools.get_portions`` that yields parts of an iterable
* Added a py.test plugin to collect ``test_*.xsh`` files and run ``test_*()`` functions.
* ``__repr__`` and ``__str__`` magic method on LazyObject
**Changed:**
* ``create_module`` implementation on XonshImportHook
* Results of the ``bash`` tab completer are now properly escaped (quoted) when necessary.
* Foreign aliases that match xonsh builtin aliases are now ignored with a warning.
* ``prompt_toolkit`` completions now only show the rightmost portion
of a given completion in the dropdown
* The value of ``'none'`` is no longer allowed for ``$SHELL_TYPE`` just during the initial
load from the environment. ``-D``, later times, and other sources still work.
* ``yacc_debug=True`` now load the parser on the same thread that the
Parser instance is created. ``setup.py`` now uses this synchronous
form as it was causing the parser table to be missed by some package
managers.
* Tilde expansion for the home directory now has the same semantics as Bash.
Previously it only matched leading tildes.
* Context sensitive AST transformation now checks that all names in an
expression are in scope. If they are, then Python mode is retained. However,
if even one is missing, subprocess wrapping is attempted. Previously, only the
left-most name was examined for being within scope.
* ``dirstack.pushd`` and ``dirstack.popd`` now handle UNC paths (of form ``\\<server>\<share>\...``), but only on Windows.
They emulate behavior of `CMD.EXE` by creating a temporary mapped drive letter (starting from z: down) to replace
the ``\\<server>\<share>`` portion of the path, on the ``pushd`` and unmapping the drive letter when all references
to it are popped.
* And ``dirstack`` suppresses this temporary drive mapping funky jive if registry entry
``HKCU\software\microsoft\command processor\DisableUNCCheck`` (or HKLM\...) is a DWORD value 1. This allows Xonsh
to show the actual UNC path in your prompt string and *also* allows subprocess commands invoking `CMD.EXE` to run in
the expected working directory. See https://support.microsoft.com/en-us/kb/156276 to satisfy any lingering curiosity.
* ``lazy_locate_binary`` handles binary on different drive letter than current working directory (on Windows).
* ``_curr_session_parser`` now iterates over ``History``
* New implementation of bash completer with better performance and compatibility.
* ``$COMPLETIONS_BRACKETS`` is now available to determine whether or not to
include opening brackets in Python completions
* ``xonsh.bat`` tries to use `pylauncher <https://www.python.org/dev/peps/pep-0397/>`_ when available.
**Removed:**
* ``History`` method ``show``
* ``_hist_get_portion`` in favor of ``tools.get_portions``
* Unused imports in proc, flake8.
**Fixed:**
* xonsh modules imported now have the __file__ attribute
* Context senstitive AST transformer was not adding argument names to the
local scope. This would then enable extraneous subprocess mode wrapping
for expressions whose leftmost name was function argument. This has been
fixed by properly adding the argument names to the scope.
* Foreign shell functions that are mapped to empty filenames no longer
receive alaises since they can't be found to source later.
* Correctly preserve arguments given to xon.sh, in case there are quoted ones.
* Environment variables in subprocess mode were not being expanded
unless they were in a sting. They are now expanded properly.
* Fixed a bug that prevented xonsh from running scripts with code caching disabled.
* Text of instructions to download missing program now does not get off and
appears in whole.
* Fix some test problems when win_unicode_console was installed on windows.
* Fixed bug that prompt string and ``$PWD`` failed to track change in actual working directory if the
invoked Python function happened to change it (e.g via ```os.chdir()```. Fix is to update ``$PWD``
after each command in ```BaseShell.default()```.
* The interactive prompt now correctly handles multiline strings.
* ``cd \\<server>\<share>`` now works when $AUTO_PUSHD is set, either creating a temporary mapped drive or simply
setting UNC working directory based on registry ``DisableUNCCheck``. However, if $AUTO_PUSHD is not set and UNC
checking is enabled (default for Windows), it issues an error message and fails. This improves on prior behavior,
which would fail to change the current working directory, but would set $PWD and prompt string to the UNC path,
creating false expectations.
* fix parsing for tuple of tuples (like `(),()`)
* ``sys.stdin``, ``sys.stdout``, ``sys.stderr`` no longer complete with
opening square brackets
* xonsh now properly handles syntax error messages arising from using values in inappropriate contexts (e.g., ``del 7``).
