2.8.0 - Wed Feb 24, 2016
------------------------------------------------------------------------------
Bugs:
* :issue:`310` - Resolved issue where console/file logs had duplicate
entries under certain circumstances.
* :issue:`314` - Resolved inconsistent behavor in ``colorlog`` extension.
* :issue:`316` - Running Nose tests with ``-s`` option causes traceback
* :issue:`317` - Calling ``CementApp.run()`` should return results from
``Controller._dispatch()``
* :issue:`320` - Partials not rendering with Mustache templates
* :issue:`325` - Wrap Utility Doesn't Support Unicode
* :issue:`328` - Post Run Hook Not Executing
* :issue:`331` - KeyError: 'USER' When Running Nose Tests
* :issue:`338` - Support non-ascii encoding for email subject and body
Features:
* :issue:`205` - Added new ``ArgparseController`` and ``expose`` decorator
in ``ext_argparse`` to eventually replace ``CementBaseController``.
* :issue:`299` - Added Argcomplete Framework Extension
* :issue:`322` - Added Tabulate Framework Extension (tabulatized output)
* :issue:`336` - Added Support for ``CementApp.reload()`` (SIGHUP)

Refactoring:
* :issue:`311` - Refactor Hooks/Handlers into CementApp
* :issue:`319` - Use ``os.devnull`` instead of internal ``NullOut`` hack.
Incompatible:
* :issue:`311` - Hook ``signal`` now requires ``app`` argument.
* :issue:`313` - Default ``Cement.Meta.exit_on_close`` to ``False``.
Calls to ``sys.exit()`` should be explicit by the app developer, and
not implied by the framework.
* :issue:`332` - Output Handler Interface Must Support Keyword Arguments
2.6.0 - Thu May 14, 2015
------------------------------------------------------------------------------
Bugs:
* :issue:`294` - Added work-around for scenario where an app wants to
support arbitrary positional argument with a value of ``default``.
By default, this will attempt to explicitly call the ``default`` command
rather than using ``default`` as the argument. This fix adds
``CementBaseController.Meta.default_func`` allowing the developer to
override the name of the default function that is called if no matching
sub-command is passed.
Features:
* :issue:`197` - Added support for colorized logging.
* :issue:`281` - Added support for Python `with` statement.
* :issue:`282` - Added support to define/register hooks and handlers via
``CementApp.Meta``.
* :issue:`290` - Added ability to disable Cement framework logging via
``CementApp.Meta.framework_logging = False``.
* :issue:`297` - Added **experimental** support for reloading
configurations anytime config files and/or plugin config files are
modified. Optional extension `ext_reload_config`.
Incompatible:
* :issue:`308` - No longer require explicit
``CementApp.Meta.base_controller`` if a controller with the label of
``base`` is registered. This is potentially backward in-compatible in
that previously ``CementBaseController.Meta.label`` defaulted to
``base``. It now defaults to ``None``, which makes more sense but will
break for any controllers that have not explicitly set a ``label`` of
``base``.
2.4.0 - Wed Sep 17, 2014
------------------------------------------------------------------------------
Bugs:
* :issue:`211` - LoggingLogHandler namespace causes issues (regression)
* :issue:`235` - Duplicate Config Section when plugin already loaded
* :issue:`246` - Plugin extension does not disable after already being
enabled
Features:
* :issue:`119` - Added cement.utils.shell.Prompt to quickly gather user
input in several different ways.
* :issue:`182` - Added a mail interface with basic implementations of
'dummy' (just prints message to console) and 'smtp'
* :issue:`229` - Ability to override handlers via command line options.
Also related: :issue:`225`.
* :issue:`248` - Added documentation for BASH Auto-Completion example.
* :issue:`249` - Allow utils.shell.exec_cmd* to accept additional.
parameters, passing all `args` and `kwargs` down to subprocess.Popen.
Allows features such as changing the current working directory, and
setting a timeout value, etc (everything that Popen supports).
* :issue:`257` - CementBaseController._dispatch() should return result
of controller function.
* :issue:`259` - Add yaml and yaml_configobj config handlers.
* :issue:`262` - Add json and json_configobj config handlers.
* :issue:`267` - Add support for multiple `plugin_dirs` and
`plugin_config_dirs`
* :issue:`269` - Allow app.close() to accept an exit code, and exit with
that code.
* :issue:`270` - Add support for multiple template_dirs
* :issue:`274` - Add cement.core.interface.list function
* :issue:`275` - Added `examples/` directory with working examples based
on Examples section of the documentation.
Incompatible:
* :issue:`227` - Standardize handler config section naming conventions.
All handler config sections are now labeled after ``interface.handler``
(i.e. ``output.json``, or ``mail.sendgrid``, etc).
* :issue:`229` - Handler override options deprecate the use of ``--json``,
and ``--yaml`` output handler options.
* :issue:`260` - Extensions/Plugins/Bootstrap modules must accept `app`
argument in `load()` function. See Upgrading doc for more information.
2.2.0 - Wed Jan 29, 2014
------------------------------------------------------------------------------
Bugs:
* :issue:`211` - LoggingLogHandler namespace causes issues
* :issue:`215` - Epilog not printed on --help
Features:
* :issue:`209` - Added app.debug property to allow developers to know if
`--debug` was passed at command line of via the config
* :issue:`219` - Merged ext.memcached into mainline
* :issue:`222` - Merged ext.configobj into mainline
* :issue:`223` - Merged ext.genshi into mainline
* :issue:`224` - Merged ext.yaml into mainline
Incompatible:
* :issue:`202` - Deprecated namespace packaging for cement and cement.ext.
Resolves issues with certain IDE's and other situations where the lack
of a proper ``__init__.py`` causes issues. This change means that
external extensions can no longer share the ``cement.ext`` module
namespace, and must have it's own unique module path.
Misc:
* Official Git repo relocated to: http://github.com/datafolklabs/cement
2.1.4 - Tue Oct 29, 2013
------------------------------------------------------------------------------
Bugs:
* :issue:`191` - KeyError when using minimal logger with --debug
* :issue:`199` - Moved post_argument_parsing hook down, after
arguments_override_config logic happens.
* :issue:`204` - utils.misc.wrap should handle None type
* :issue:`208` - LoggingLogHandler does not honor Meta.config_section
Features:
* :issue:`190` - Merged daemon extension into core
* :issue:`194` - Added pre_argument_parsing/post_argument_parsing hooks
* :issue:`196` - Added utils.misc.wrap
* :issue:`200` - Merged ext.mustache into mainline.
* :issue:`203` - Added support for external template directory
* :issue:`207` - Added support for alternative 'display' name for stacked
controllers
Incompatible:
* :issue:`163` - LoggingLogHandler.Meta.clear_loggers was changed from a
boolean option, to a list. Additionally,
LoggingLogHandler.clear_loggers() now requires a `namespace` argument.
ILog interface no longer defines `clear_loggers()` as a required
function (though ILog interfaces are welcome to implement one if
necessary).
* :issue:`173` - Deprecated 'has_key()' from configparser extension
* :issue:`201` - Add Deprecation Warning for CementApp.get_last_rendered()
2.1.2 - Thu Nov 1st, 2012
------------------------------------------------------------------------------
This is a branch off of the 2.0.x stable code base. Maintenance releases for
2.0.x will happen under the stable/2.0.x git branch, while forward feature
development will happen here under as 2.1.x under the git master branch.
Bugs:
* :issue:`162` - Unable to set log 'level' by config
* :issue:`167` - Non-stacked controllers not listed in --help
* :issue:`169` - Fixed tests.utils.shell_tests timeout issue
* :issue:`171` - No handlers could be found for logger
* :issue:`183` - os.environ['HOME'] does not exist on Windows
Features:
* :issue:`161` - Ability to override `usage`
* :issue:`164` - Store previously rendered data as app._last_rendered, and
retrievable by app.get_last_rendered().
* :issue:`165` - Allow utils.fs.backup() to support a suffix kwarg
* :issue:`166` - Ability to set the 'app' for CementTestCase.make_app()
* :issue:`170` - Added support for `nested` and `embedded` controllers.
Misc:
* :issue:`172` - 100% PEP8 Compliant
* :issue:`160` - Refactor CementApp._resolve_handler() as
handler.resolve()
Deprecation Notices:
* :issue:`173` - ConfigParserConfigHandler.has_key() is now deprecated,
and will be removed in future versions. Please use `if key in
app.config.keys(section)` instead.
Incompatible Changes:
* :issue:`141` - Removed shortcuts from CementBaseController (such as
log, pargs, etc). Use `self.app.<shortcut>` instead.
* :issue:`167` - Listed above, in order to fix this issue as well as
restrict future issues we implemented a hard requirement that all
base controllers have the label 'base'. This should not be a major
change for anyone using Cement 2.0.x as it is a simple 1 line change
in any one application. As all documentation encourages the use of the
label 'base' it should not be a wide spread incompatibility.
* :issue:`179` - CementBaseController `hidden`, `visible`, and `exposed`
have been removed, and replaced by other private means of managing
the dispatch of commands.
* CementBaseController no longer implements a `default` command.
* :issue:`177` - Renamed several cement.core.backend pieces including:
`handlers` -> `__handlers__`, `hooks` -> `__hooks__`, `SAVED_STDOUT`
-> `__saved_stdout__`, and `SAVED_STDERR` -> `__saved_stderr__`.
* :issue:`178` - Moved `backend.defaults()` to
`utils.misc.init_defaults()`, and `backend.minimal_logger()` to
`utils.misc.minimal_logger()`
2.0.0 - Fri Aug 03, 2012
------------------------------------------------------------------------------
This is the initial stable release of the 2.0.x branch. Future releases of
this branch will include bug/security fixes and minor feature updates.
Forward moving feature development will continue out of the 2.1.x branch.
Bugs:
* :issue:`143` - Incorrect doc regarding logging. The LoggingLogHandler
now supports an optional 'namespace' argument allowing the developer
to override the log prefix.
* :issue:`150` - foundation.CementApp.Meta.argv now defaults to None,
but is overridden in __init__() with sys.argv if no other argv is
passed as meta.
Features:
* :issue:`138` - Added 'shell' argument to utils.shell.exec_cmd() and
utils.shell.exec_cmd2().
* :issue:`140` - Included ~/.myapp/config in default config search
* :issue:`144` - Added a note on Contributing, as well as a CONTRIBUTORS
file.
* :issue:`152` - Added 'argument_formatter' to ControllerBaseClass.Meta.
* :issue:`153` - Added spawn_process() and spawn_thread() to utils.shell.
Incompatible Changes:
* :issue:`100` - Interfaces audit.
* ILog.level() redefined as ILog.get_level()
* IPlugin.loaded_plugins attribute redefined as
IPlugin.get_loaded_plugins()
* IPlugin.enable_plugins attribute redefined as
IPlugin.get_enabled_plugins()
* IPlugin.disabled_plugins attribute redefined as
IPlugin.get_disabled_plugins()
* :issue:`145` - The IArgument interface no longer specifies that the
`parsed_args` be maintained by the handler implementation. This means
that `app.args.parsed_args` is no longer available, however
`app.pargs` functions just the same as it points to
`app._parsed_args`.
* :issue:`148` - The CementExtensionHandler.loaded_extensions property is
now a callable at CementExtensionHandler.get_loaded_extensions().
* :issue:`151` - Removed all previously deprecated code including:
* Removed CementApp.Meta.defaults, and CementBaseHandler.Meta.defaults.
Now use `config_defaults` instead.
* Removed cement.foundation.lay_cement(). Now use CementApp directly.
* Removed cement.handler.enabled(). Now use `handler.registered()`
instead.
* :issue:`154` - Validate for handler config_defaults and config_section
by default. Only incompatible if not previously sub-classing from
handler.CementBaseHandler.
* :issue:`157` - CementRuntimeError renamed as FrameworkError
* :issue:`158` - CementSignalError renamed as CaughtSignal
* :issue:`159` - CementInterfaceError renamed as InterfaceError
Misc:
* :issue:`155` - Removed unused CementArgumentError, and
CementConfigError. These types of exceptions should be defined at
the application level.

* :issue:`127` - Inherited positional arguments listed multiple times
Feature Enhancements:
* :issue:`131` - Controller aliases
* :issue:`126` - Add a 'bootstrap' importer to CementApp
* Added cement.utils.test.CementTestCase for improved testing.
Incompatible Changes:
* :issue:`129` - Simplify extensions/plugins/hooks/etc.
* Hooks renamed from 'cement_xxx_hook' to just 'xxx'. For example, the
'cement_pre_setup_hook' is now simply 'pre_setup'. Additionally, the
'cement_on_close_hook' is now broken out into 'pre_close', and
'post_close'.
* The cement.core.hooks.register decorator was replaced with a simple
function of the same name. New usage is:
register('hook_name', hook_func).
* Plugins, extensions, and the application bootstrap now attempt to
call a 'load()' function, meaning library code and loading code can
live in the same file (i.e. hooks won't be registered just because
you imported an extension to sub-class a handler, etc).
* cement.utils.test_helper moved to cement.utils.test.
* By default, command line arguments no longer override config settings.
This is now configurable by the CementApp.Meta.arguments_override_config
boolean. Related: :issue:`136`.
