# pyegeria: a python client for Egeria

A lightweight Python 3.12+ client and CLI for the Egeria open metadata and governance platform. It helps you configure and operate Egeria services and work with metadata (assets, glossaries, lineage, etc.) from Python, with examples, tests, and documented report formats.

This is a package for easily using the Egeria
open metadata environment from python. Details about the
open source Egeria project can be found at [Egeria Project](https://egeria-project.org).

This package is in active development. There is initial
support for many of Egeria's services including configuration and operation.  This client depends on 
This release supports Egeria 6.0 - although most of the functions may work on earlier versions of Egeria as well. 

The code is organized to mimic the existing Egeria Java Client structure.

The commands folder holds the Egeria Command Line Interface and corresponding commands
to visualize and use Egeria. The commands also serve as useful examples.

An examples folder holds some useful examples showing different facets of using pyegeria.

For detailed guidance on output formats and report specs (including nested/master–detail), see:
- docs/output-formats-and-report-specs.md

### Report specs: families and filtering

Report specs (aka format sets) can be tagged with an optional `family` string to help organize and discover related specs.

- Show names with family and sort by family, then name:

```python
from pyegeria.view.base_report_formats import report_spec_list

names = report_spec_list(show_family=True, sort_by_family=True)
for n in names:
  print(n)
```

- Filter specs by family programmatically:

```python
from pyegeria.view.base_report_formats import report_specs

# Exact family match (case-insensitive)
security_specs = report_specs.filter_by_family("Security")
# Specs with no family assigned
no_family_specs = report_specs.filter_by_family("")
```

WARNING: files that start with "X" are in-progress placeholders that are not meant to be used..they will mature and 
evolve.

This is a learning experience.

## Configuration

pyegeria uses a simple, predictable precedence for configuration:

1. Built-in defaults (Pydantic models in pyegeria.config)
2. Config file (JSON) if found
3. Environment variables (OS env and optional .env)
4. Explicit env file passed to get_app_config/load_app_config

Environment always overrides config file, which overrides defaults.

### Where to put your configuration

- Config file: A JSON file named config.json. The loader looks in this order:
  - If PYEGERIA_CONFIG_DIRECTORY is set: $PYEGERIA_CONFIG_DIRECTORY/$PYEGERIA_CONFIG_FILE
  - Else if PYEGERIA_ROOT_PATH is set: $PYEGERIA_ROOT_PATH/$PYEGERIA_CONFIG_FILE
  - Else: ./config.json (the current working directory)

- .env file: Optional. If present in the current working directory (.env), variables from it will be loaded. You can also pass a specific env file path to get_app_config(env_file=...) or load_app_config(env_file=...). For sample variables, see config/env in this repo.

### Common environment variables

- PYEGERIA_CONFIG_DIRECTORY: directory containing your config.json
- PYEGERIA_ROOT_PATH: root folder used to resolve config.json when CONFIG_DIRECTORY is not set
- PYEGERIA_CONFIG_FILE: filename of the configuration JSON (default: config.json)
- PYEGERIA_CONSOLE_WIDTH: integer console width (e.g., 200 or 280)
- EGERIA_PLATFORM_URL, EGERIA_VIEW_SERVER_URL, EGERIA_ENGINE_HOST_URL: URLs for your Egeria servers
- EGERIA_USER, EGERIA_USER_PASSWORD: credentials used by some clients
- Logging related: PYEGERIA_ENABLE_LOGGING, PYEGERIA_LOG_DIRECTORY, PYEGERIA_CONSOLE_LOG_LVL, PYEGERIA_FILE_LOG_LVL, etc.

See config/env for more variables and defaults.

### Example .env

# PYEGERIA_CONFIG_DIRECTORY=/path/to/configs
# PYEGERIA_ROOT_PATH=/path/to/project
# PYEGERIA_CONFIG_FILE=config.json
# EGERIA_PLATFORM_URL=https://localhost:9443
# EGERIA_VIEW_SERVER=qs-view-server
# EGERIA_VIEW_SERVER_URL=https://localhost:9443
# EGERIA_USER=myuser
# EGERIA_USER_PASSWORD=mypassword
# PYEGERIA_CONSOLE_WIDTH=280

Lines starting with # are comments. Quotes are optional; python-dotenv/pydantic-settings handle both.

### Example config.json (minimal)

{
  "Environment": {
    "Pyegeria Root": ".",
    "Egeria Platform URL": "https://localhost:9443"
  },
  "User Profile": {
    "Egeria Home Collection": "MyHome"
  }
}

### Programmatic usage

from pyegeria import get_app_config
cfg = get_app_config()  # uses OS env and ./.env
# or with explicit env file
cfg = get_app_config(env_file="/path/to/dev.env")

# Access values via Pydantic models
print(cfg.Environment.egeria_platform_url)
print(cfg.Logging.enable_logging)

### CLI quick checks

- Validate your env file:
  python scripts/validate_env.py --env config/env
  python scripts/validate_env.py               # auto-detects ./config/env or ./.env

### Testing

By default, running pytest executes unit tests that use monkeypatching/fakes and do not contact a live Egeria.

- Run unit tests (recommended default):
  poetry install
  poetry run pytest -v

You can also run tests live against a local Egeria instance. Enable live mode with either a CLI flag or an environment variable. In live mode, tests marked as `unit` are skipped and live tests run using a real Client2 connection.

- Enable live mode via CLI:
  poetry run pytest -q --live-egeria

- Or enable via environment variable:
  PYEG_LIVE_EGERIA=1 poetry run pytest -q

Default live connection parameters (can be overridden via env):
- server_name = "qs-view-server"           (override with PYEG_SERVER_NAME)
- platform_url = "https://localhost:9443" (override with PYEG_PLATFORM_URL)
- user_id = "peterprofile"                (override with PYEG_USER_ID)
- user_pwd = "secret"                      (override with PYEG_USER_PWD)

Notes:
- SSL verification is controlled by pyegeria._globals.enable_ssl_check, which defaults to False in this repo to support localhost/self-signed certs.
- See tests/conftest.py for the live test fixtures and switches.

### Troubleshooting

### Troubleshooting

- If your env doesn’t seem to apply, confirm which config.json is used (the loader checks PYEGERIA_CONFIG_DIRECTORY first, then PYEGERIA_ROOT_PATH, then ./config.json).
- .env files are optional. Missing .env is not an error.
- You can always override values with OS environment variables (they take precedence over config.json).
