app_skellington
Application framework for Python, features include:
- Pain-free multi-level command menu: Expose public class methods as commands available to user.
- Simple to define services and automatic dependency injection based on name (with custom invocation as an option). *WIP
- INI-style config and and validation (provided through ConfigObj).
- Colored logging (provided through colorlog)
- Works on Linux, Windows, and Mac.
Principles:
- Lend to creating beautiful, easy to read and understand code in the application.
- Minimize coupling of applications to this framework.
- Compatible with Linux, Windows, and Mac. Try to be compatible as possible otherwise.
- Try to be compatible with alternate Python runtimes such as PyPy and older python environments. *WIP

Application Configuration
Site configurations are supported through ConfigObj. There is a config.spec in the src directory which is a validation file; it contains the accepted parameter names, types, and limits for configurable options in the application which is built on app_skellington. The format is multi-level .ini syntax.
Reference the ConfigObj documentation for config.ini and config.spec format. See:
- https://configobj.readthedocs.io/en/latest/configobj.html#the-config-file-format
- https://configobj.readthedocs.io/en/latest/configobj.html#validation
Config files (config.ini) are created if they don't exist. The file always contains the full specification of parameters; i.e. even default parameters are added into the config file.
Linux:
- /home/<user>/.config/<app_name>/config.ini
- /home/<user>/.cache/<app_name>/log/<app_name>.log
Windows:
- C:\Users\<user>\<app_name>\Local\<app_name>\config.ini
- C:\Users\<user>\<app_name>\Local\<app_name>\Logs\<app_name>.log
Application configuration can be overridden ad-hoc through the --config argument.
Debug - Turn on Logging
Set 'APPSKELLINGTON_ENABLE_LOGGING' environment variable to any value which turns on AppSkellington-level logging. For example,
APPSKELLINGTON_DEBUG=1 <executable>
or
export APPSKELLINGTON_DEBUG=1
<executable>
Tests
Tests are a WIP. Recommendation is to run 'pytest' in the 'tests' directory.
Development
I recommend pyenv to install a reliable, controlled python of preferred version locally.
curl https://pyenv.run | bash
# Add to .bashrc or similar for different shells:
tee -a "$HOME"/.profile <<'EOF'
export PYENV_ROOT="$HOME/.pyenv"
[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init -)"
EOF
