====================
**Added:**
* $XONTRIB_MPL_MINIMAL environment variable can be set to change if plots are minimalist or as-seen
* xontrib-mpl now supports iTerm2 inline image display if iterm2_tools python package is installed
* Xonsh now will fallback to other shells if encountered errors when
starting up.
* Added entry to customization faq re: ``dirs`` alias (1452)
* Added entry to customization faq re: tab completion selection (1725)
* Added entry to customization faq re: libgcc core dump (1160)
* Section about quoting in the tutorial.
* The ``$VC_HG_SHOW_BRANCH`` environment variable to control whether to hide the hg branch in the prompt.
* xonfig now contains the latest git commit date if xonsh installed
from source.
* Alt+Enter will execute a multiline code block irrespective of cursor position
* Windows now has the ability to read output asynchronously from
the console.
* Use `doctr <https://drdoctr.github.io/doctr/>`_ to deploy dev docs to github pages
* New ``xonsh.proc.uncapturable()`` decorator for declaring that function
aliases should not be run in a captured subprocess.
* New history backend sqlite.
* Prompt user to install xontrib package if they try to load an uninstalled
xontrib
* Callable aliases may now take a final ``spec`` argument, which is the
corresponding ``SubprocSpec`` instance.
* New ``bashisms`` xontrib provides additional Bash-like syntax, such as ``!!``.
This xontrib only affects the command line, and not xonsh scripts.
* Tests that create testing repos (git, hg)
* New subprocess specification class ``SubprocSpec`` is used for specifying
and manipulating subprocess classes prior to execution.
* New ``PopenThread`` class runs subprocesses on a a separate thread.
* New ``CommandPipeline`` and ``HiddenCommandPipeline`` classes manage the
execution of a pipeline of commands via the execution of the last command
in the pipeline. Instances may be iterated and stream lines from the
stdout buffer. These pipelines read from the stdout & stderr streams in a
non-blocking manner.
* ``$XONSH_STORE_STDOUT`` is now available on all platforms!
* The ``CommandsCache`` now has the ability to predict whether or not a
command must be run in the foreground using ``Popen`` or may use a
background thread and can use ``PopenThread``.
* Callable aliases may now use the full gamut of functions signatures:
``f()``, ``f(args)``, ``f(args, stdin=None)``,
``f(args, stdin=None, stdout=None)``, and `
``f(args, stdin=None, stdout=None, stderr=None)``.
* Uncaptured subprocesses now receive a PTY file handle for stdout and
stderr.
* New ``$XONSH_PROC_FREQUENCY`` environment variable that specifies how long
loops in the subprocess framework should sleep. This may be adjusted from
its default value to improved performance and mitigate "leaky" pipes on
slower machines.
* ``Shift+Tab`` moves backwards in completion dropdown in prompt_toolkit
* PromptFormatter class that holds all the related prompt methods
* PromptFormatter caching when building the prompt
* p-strings: ``p'/foo/bar'`` is short for ``pathlib.Path('/foo/bar')``
* byte strings: prefixes other than ``b'foo'`` (eg, ``RB'foo'``) now work
* Backticks for regex or glob searches now support an additional modifier
``p``, which causes them to return Path objects instead of strings.
* New ``BOTTOM_TOOLBAR`` environment variable to control a bottom toolbar as specified in prompt-toolkit
* New ``$XONSH_STDERR_PREFIX`` and ``$XONSH_STDERR_POSTFIX`` environment
variables allow the user to print a prompt-like string before and after
all stderr that is seen. For example, say that you would like stderr
to appear on a red background, you might set
``$XONSH_STDERR_PREFIX = "{BACKGROUND_RED}"`` and
``$XONSH_STDERR_PREFIX = "{NO_COLOR}"``.
* New ``xonsh.pyghooks.XonshTerminal256Formatter`` class patches
the pygments formatter to understand xonsh color token semantics.
* Load events are now available
* New events added: ``on_post_init``, ``on_pre_cmdloop``, ``on_pre_rc``, ``on_post_rc``, ``on_ptk_create``
* Completion for ``xonsh`` builtin functions ``xontrib`` and ``xonfig``
* Added a general customization FAQ page to the docs to collect various
tips/tricks/fixes for common issues/requests
* ``test_single_command`` and ``test_redirect_out_to_file`` tests in ``test_integrations``
* Add note that the target of redirection should be separated by a space.
**Changed:**
* CircleCI now handles flake8 checks
* Travis doesn't allow failures on nightly
* ``get_hg_branch`` runs ``hg root`` to find root dir and check if we're in repo
* The default style will now use the color keywords (ansired, ansidarkred)
to set colors that follow the terminal color schemes. Currently, this requires
prompt_toolkit master (>1.0.8) and pygments master (2.2) to work correctly.
* ``vox activate`` now accepts relative directories.
* Updated the effectivity of ``$XONSH_DEBUG`` on debug messages.
* Better documentation on how to get nice colors in Windows' default console
* All custom prompt_toolkit key binding filters now declared with the
``Condition`` decorator
* The style for the prompt toolkit completion menu is now lightgray/darkgray instead of turquoise/teal
* landscape.io linting now ignores ply directory
* ``history`` help messages to reflect subcommand usage
* Quote all paths when completion if any of the paths needs be quoted,
so that bash can automatically complete to the max prefix of the paths.
* Tee'd reads now occur in 1kb chunks, rather than character-by-character.
* The ``which`` alias no longer has a trailing newline if it is captured.
This means that ``$(which cmd)`` will simply be the path to the command.
* The following commands are, by default, predicted to be not threadable
in some circumstances:
* bash
* csh
* clear
* clear.exe
* cls
* cmd
* ex
* fish
* htop
* ksh
* less
* man
* more
* mutt
* nano
* psql
* ranger
* rview
* rvim
* scp
* sh
* ssh
* startx
* sudo
* tcsh
* top
* vi
* view
* vim
* vimpager
* xo
* xonsh
* zsh
* The ``run_subproc()`` function has been replaced with a new implementation.
* Piping between processes now uses OS pipes.
* ``$XONSH_STORE_STDIN`` now uses ``os.pread()`` rather than ``tee`` and a new
file.
* The implementation of the ``foreground()`` decorator has been moved to
``unthreadable()``.
* ``voxapi.Vox`` now supports ``pathlib.Path`` and ``PathLike`` objects as virtual environment identifiers
* Renamed FORMATTER_DICT to PROMPT_FIELDS
* BaseShell instantiates PromptFormatter
* readline/ptk shells use PromptFormatter
* Updated the bundled version of ``ply`` to current master available
* vended ``ply`` is now a git subtree to help with any future updates
* ``WHITE`` color keyword now means lightgray and ``INTENSE_WHITE`` completely white
* Removed ``add_to_shell`` doc section from ``*nix`` install pages and instead
relocated it to the general customization page
* Moved a few ``*nix`` customization tips from the linux install page to the general
customization page
**Removed:**
* coverage checks
* ``CompletedCommand`` and ``HiddenCompletedCommand`` classes have been removed
in favor of ``CommandPipeline`` and ``HiddenCommandPipeline``.
* ``SimpleProcProxy`` and ``SimpleForegroundProcProxy`` have been removed
in favor of a more general mechanism for dispatching callable aliases
implemented in the ``ProcProxyThread`` and ``ProcProxy`` classes.
* ``test_run_subproc.py`` in favor of ``test_integrations.py``
* Unused imports in many tests
* Many duplicated tests (copypasta)
**Fixed:**
* xontrib-mpl now preserves the figure and does not permanently alter it for viewing
* Fix up small pep8 violations
* Fixed a bug where some files are not showing using bash completer
* Fixed some issues with subprocess capturing aliases that it probably
shouldn't.
* ``safe_readable()`` now checks for ``ValueError`` as well.
* The scroll bars in the PTK completions menus are back.
* Jupyter kernel installation now respects the setuptools ``root`` parameter.
* Fix ``__repr__`` and ``__str__`` methods of ``SubprocSpec`` so they report
correctly
* Fixed the message printed when which is unable to find the command.
* Fixed a handful of sphinx errors and warnings in the docs
* Fixed many PEP8 violations that had gone unnoticed
* Fix failure to detect an Anaconda python distribution if the python was install from the conda-forge channel.
* current_branch will try and locate the vc binary once
* May now Crtl-C out of an infinite loop with a subprocess, such as
while True: sleep 1``.
* Fix for stdin redirects.
* Backgrounding works with ``$XONSH_STORE_STDOUT``
* ``PopenThread`` blocks its thread from finishing until command has completed
or process is suspended.
* Added a minimum time buffer time for command pipelines to check for
if previous commands have executed successfully. This is helpful
for pipelines where the last command takes a long time to start up,
such as GNU Parallel. This also checks to make sure that output has occurred.
This includes piping 2+ commands together and pipelines that end in
unthreadable commands.
* ``curr_branch`` reports correctly when ``git config status.short true`` is used
* ``pip`` completion now filters results by prefix
* Fixed streaming ``!(alias)`` repr evaluation where bytes where not
streamed.
* Aliases that begin with a comma now complete correctly (no spurious comma)
* Use ``python3`` in shebang lines for compatibility with distros that still use Python 2 as the default Python
* STDOUT is only stored when ``$XONSH_STORE_STDOUT=True``
* Fixed issue with alias redirections to files throwing an OSError because
the function ProcProxies were not being waited upon.
* Fixed issue with callable aliases that happen to call sys.exit() or
raise SystemExit taking out the whole xonsh process.
* Safely flushes file handles on threaded buffers.
* Proper default value and documentation for ``$BASH_COMPLETIONS``
* Fixed readline completer issues on paths with spaces
* Fix bug in ``argvquote()`` functions used when sourcing batch files on Windows. The bug meant an extra backslash was added to UNC paths.
Thanks to bytesemantics for spotting it, and janschulz for fixing the issue.
* pep8, lint and refactor in pytest style of ``test_ptk_multiline.py``, ``test_replay.py``
* Tab completion of aliases returned a upper cased alias on Windows.
* History show all action now also include current session items.
* ``proc.stream_stderr`` now handles stderr that doesn't have buffer attribute
* Made ``history show`` result sorted.
* Fixed issue that ``history gc`` does not delete empty history files.
* Standard stream tees have been fixed to accept the possibility that
they may not be backed by a binary buffer. This includes the pipeline
stdout tee as well as the shell tees.
* Fixed a bug when the pygments plugin was used by third party editors etc.
* CPU usage of ``PopenThread`` and ``CommandPipeline`` has been brought
down significantly.
