`shepherd-core` is designed as a library and bundles data-models and file-access-routines for the shepherd-testbed, that are used by several codebases.
For postprocessing shepherds .h5-files usage of [shepherd_data](https://pypi.org/project/shepherd_data) is recommended.
## Features
- read and write shepherds hdf5-files
- create, read, write and convert experiments for the testbed
- all required data-models are included
- simulate the virtual source, including virtual harvesters (and virtual converter as a whole)
- connect and query the testbed via a webclient (TestbedClient in alpha-stage)
- offline usage defaults to static demo-fixtures loaded from yaml-files in the model-directories
- work with target-firmwares
- embed, modify, verify, convert
- **Note**: working with ELF-files requires external dependencies, see ``Installation``-Chapter
- decode waveforms (gpio-state & timestamp) to UART
- create an inventory (for deployed versions of software, hardware)
See [official documentation](https://orgua.github.io/shepherd) or [example scripts](https://github.com/orgua/shepherd-datalib/tree/main/shepherd_core/examples) for more details and usage. Most functionality is showcased in both. The [extra](https://github.com/orgua/shepherd-datalib/tree/main/shepherd_core/extra)-directory holds data-generators relevant for the testbed. Notably is a [trafficbench](https://github.com/orgua/TrafficBench)-experiment that's used to derive the link-matrix of the testbed-nodes.
## Config-Models in Detail
These pydantic data-models are used throughout all shepherd interfaces. Users can create an experiment, include their own content and feed it to the testbed.
- orchestration ``/data-models`` with focus on remote shepherd-testbed
- classes of sub-models
- ``/base``: base-classes, configuration and -functionality for all models
- ``/testbed``: meta-data representation of all testbed-components
- ``/content``: reusable user-defined meta-data for fw, h5 and vsrc-definitions
- ``/experiment``: configuration-models including sub-systems
- ``/task``: digestible configs for shepherd-herd or -sheep
- behavior controlled by ``ShpModel`` and ``content``-model
- a basic database is available as fixtures through a ``tb_client``
- fixtures selectable by name & ID
- fixtures support inheritance
- the models support
- auto-completion with neutral / sensible values
- complex and custom datatypes (i.e. PositiveInt, lists-checks on length)
- checking of inputs and type-casting
- generate their own schema (for web-forms)
- pre-validation
- store to & load from yaml with typecheck through wrapper
- documentation
- experiment-definition is designed securely
- types are limited in size (str)
- exposes no internal paths
- experiments can be transformed to task-sets (``TestbedTasks.from_xp()``)
## Compatibility
| OS | PyVersion | Comment |
|---------|------------|--------------------------------------------|
| Ubuntu | 3.8 - 3.13 | |
| Windows | 3.8 - 3.13 | no support for elf and hex-conversions yet |
| MacOS | 3.8 - 3.13 | hex-conversion missing |
Notes:
- hex-conversion needs a working and accessible objcopy
- elf-supports needs
- ``shepherd-core[elf]`` installs ``pwntools-elf-only``
- most elf-features also still utilize hex-conversion
## Installation
The Library is available via PyPI and can be installed with
```shell
pip install shepherd-core -U
# or for the full experience (includes core)
pip install shepherd-data -U
```
For bleeding-edge-features or dev-work it is possible to install directly from GitHub-Sources (here `dev`-branch):
```Shell
pip install git+https://github.com/orgua/shepherd-datalib.git@dev#subdirectory=shepherd_core -U
# and on sheep with newer debian
sudo pip install git+https://github.com/orgua/shepherd-datalib.git@dev#subdirectory=shepherd_core -U --break-system-packages
```
If you are working with ``.elf``-files (embedding into experiments) you make "objcopy" accessible to python. In Ubuntu, you can either install ``build-essential`` or ``binutils-$ARCH`` with arch being ``msp430`` or ``arm-none-eabi`` for the nRF52.
```shell
sudo apt install build-essential
```
For more advanced work with ``.elf``-files (modify value of symbols / target-ID) you should install
```shell
pip install shepherd-core[elf]
```
and also make sure the prereqs for the [pwntools](https://docs.pwntools.com/en/stable/install.html) are met.
For creating an inventory of the host-system you should install
```shell
pip install shepherd-core[inventory]
```
## Unittests
To run the testbench, follow these steps:
1. Navigate your host-shell into the package-folder and
2. install dependencies
3. run the testbench (~ 320 tests):
```Shell
cd shepherd-datalib/shepherd_core
pip3 install ./[tests]
pytest
```
