small toolset to properly exit a cli application:
- print the traceback information (can be set with commandline option)
- get a proper exit code from the Exception
- flush the streams, to make sure output is written in proper order
- demo how to integrate into Your cli module (see usage)

- get the system exit code
.. code-block:: python
def get_system_exit_code(exc: BaseException) -> int:
"""
Return the exit code for linux or windows os, based on the exception.
If, on windows, the winerror code is passed with the Exception, we return that winerror code.
Parameter
---------

the exception to analyze
Result
------

as integer
Examples
--------
>>> try:
... raise RuntimeError()
... except RuntimeError as my_exc:
... assert get_system_exit_code(my_exc) == 1
... setattr(my_exc, 'winerror', 42)

"""
- print the exception message
.. code-block:: python

"""
Prints the Exception Message to stderr
if trace_back is True, it also prints the traceback information
if the exception has stdout, stderr attributes (like the subprocess.CalledProcessError)
those will be also printed to stderr
Parameter
---------
trace_back
if traceback information should be printed. This is usually set early
in the CLI application to the config object via a commandline option.
length_limit
int, limits the length of the message
stream
optional, to which stream to print, default = stderr
Examples
--------
>>> # test with exc_info = None
>>> print_exception_message()
>>> # test with exc_info
>>> try:

"""
- flush the streams
.. code-block:: python
def flush_streams() -> None:
"""
flush the streams - make sure the output is written early,
otherwise the output might be printed even after another CLI
command is launched

Usage from Commandline
------------------------
.. code-block::
Usage: cli_exit_tools [OPTIONS] COMMAND [ARGS]...
functions to exit an cli application properly
Options:
--version Show the version and exit.
--traceback / --no-traceback return traceback information on cli
-h, --help Show this message and exit.
Commands:
info get program informations
Installation and Upgrade
------------------------
- Before You start, its highly recommended to update pip and setup tools:
.. code-block::
python -m pip --upgrade pip
python -m pip --upgrade setuptools
- to install the latest release from PyPi via pip (recommended):
.. code-block::
python -m pip install --upgrade cli_exit_tools
- to install the latest version from github via pip:
.. code-block::
python -m pip install --upgrade git+https://github.com/bitranox/cli_exit_tools.git
- include it into Your requirements.txt:
.. code-block::
# Insert following line in Your requirements.txt:
# for the latest Release on pypi:
cli_exit_tools
# for the latest development version :
cli_exit_tools @ git+https://github.com/bitranox/cli_exit_tools.git
# to install and upgrade all modules mentioned in requirements.txt:
python -m pip install --upgrade -r /<path>/requirements.txt
- to install the latest development version from source code:
.. code-block::
# cd ~
$ git clone https://github.com/bitranox/cli_exit_tools.git
$ cd cli_exit_tools
python setup.py install
- via makefile:
makefiles are a very convenient way to install. Here we can do much more,
like installing virtual environments, clean caches and so on.
.. code-block:: shell
# from Your shell's homedirectory:
$ git clone https://github.com/bitranox/cli_exit_tools.git
$ cd cli_exit_tools
# to run the tests:
$ make test
# to install the package
$ make install
# to clean the package
$ make clean
# uninstall the package
$ make uninstall
Requirements
------------
following modules will be automatically installed :
.. code-block:: bash
## Project Requirements
