- update to version 0.8.1
- Added:
- ``SubprocSpec`` has a new ``pipeline_index`` integer attribute that indicates
the commands position in a pipeline. For example, in
.. code-block:: sh
p = ![ls -l | grep x]
The ``ls`` command would have a pipeline index of 0
(``p.specs[0].pipeline_index == 0``) and ``grep`` would have a pipeline index
of 1 (``p.specs[1].pipeline_index == 1``). This may be usefule in callable
alaises which recieve the spec as an argument.
- Changed:
- Removed ``fish`` from list of supported foreign shells in the wizard.
- Circle CI config updated to use a pinned version of ``black`` (18.9b0)
- Pytest plugin now uses ``xonsh.main.setup()`` to setup test environment.
- Linux platform discovery will no longer use ``platform.linux_distribution()``
on Python >=3.6.6. due to pending deprecation warning.
- Updated Linux Guide as Xonsh is now available in Arch Linux official repositories.
- Fixed:
- Builtin dynamic proxies and deprecation warning proxies were not deleting
attributes and items properly.
- Fixed stdout/sdterr writing infinite recurssion error that would occur in
long pipelines of callable aliases.
- Fixed a bug which under very rare conditions could cause the shell
to die with PermissionError exception while sending SIGSTOP signal
to a child process.
- Fixed further raw string deprecation warnings thoughout the code base.
- update to version 0.8.0
- 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
- update to version 0.7.10
- Added:
- 'off' can be passed as falsy value to all flags accepting boolean argument.
- DragonFly BSD support
- Format strings (f-strings) now allow environment variables to be looked up.
For example, ``f"{$HOME}"`` will yield ``"/home/user"``. Note that this will
look up and fill in the ``detype()``-ed version of the environment variable,
i.e. it's native string representation.
- Changed:
- Running ``aurman`` command will now be predicted to be unthreaded by default.
- Fixed:
- The xonsh ``xonfig wizard`` would crash if an unknown foreign shell was
provided. This has been fixed.
- The ``hg split`` command will now predict as unthreadable.
- Fixed path completer crash on attempted f-string completion
- update to version 0.7.9
- Added:
- The python-mode ``@(expr)`` syntax may now be used inside of subprocess
arguments, not just as a stand-alone argument. For example:
.. code-block:: sh
$ x = 'hello'
$ echo /path/to/@(x)
/path/to/hello
This syntax will even properly expand to the outer product if the ``expr``
is a list (or other non-string iterable) of values:
.. code-block:: sh
$ echo /path/to/@(['hello', 'world'])
/path/to/hello /path/to/world
$ echo @(['a', 'b']):@('x', 'y')
a:x a:y b:x b:y
Previously this was not possible.
- New ``$DOTGLOB`` environment variable enables globs to match
"hidden" files which start with a literal ``.``. Set this
variable to ``True`` to get this matching behavior.
Cooresponding API changes have been made to
``xonsh.tools.globpath()`` and ``xonsh.tools.iglobpath()``
- New environment variable ``$FOREIGN_ALIASES_SUPPRESS_SKIP_MESSAGE``
enables the removal of skipping foreign alias messages.
- New ``--suppress-skip-message`` command line option for skipping
foreign alias messages when sourcing foreign shells.
- Fixed:
- In Bash completions, if there are no files to source, a ``set()`` will
no longer be inserted into the completion script.
- Fixed issue with TAB completion in readline not replacing values
with spaces properly when the prefix was unquoted.
- update to version 0.7.8
- Added:
- ``xonsh.lib.collections.ChainDB``, a chain map which merges mergable fields
- Fixed:
- Pass all params to voxapi.create
- PTK tab-completion now auto-accepts completion if only one option is present
(note that fix is only for PTK2)
