**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

# Python Package Index (PyPi) - Installation Instruction

This is the project page for PyPi: The Python Package Index for community third-party libraries

https://pypi.org/project/app-skellington/

```
pip install app_skellington          # install
pip uninstall app_skellington        # uninstall
pip download app_skellington         # download .whl wheel files for redistributable install
pip install -U app_skellington       # upgrade
pip list                             # list install packages in environment
pip index version app_skellington    # enumerate available distributions in pypi for package
```

# Description

This is a library. There is nothing to run by itself. It would be helpful to have a sample application that uses
it or something, but I don't have that ready at the moment.

# 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 <filename>
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 and not fully built out yet. 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
```
 * reference https://github.com/pyenv/pyenv
 * Use pyenv to install desired python version, and/or create any virtual environments you desire

Publish:

```
# Push latest commit, or on commit ready to publish:
git push

# Create a tag with the desired version number and push:
git tag -a v0.2.0 -m "0.2.0 provides modern pyproject.toml build with setuptools, versioning, and publishing"
git push origin v0.2.0

# Build the wheel:
python -m build

# Publish to pypi:
twine check dist/*
twine upload dist/*
```

# Version

setuptools_scm will infer the version based on the latest tag in your Git history.
Ensure you are tagging your commits with meaningful version numbers like v1.0.0, v1.1.0, etc.

You can view the current version number with the command:

    python -m setuptools_scm
