gpp-client 25.5.0a0

Gemini Program Platform client.

GPP Client

---

Pain-free python/CLI communication with the Gemini Program Platform (GPP).

Documentation: https://gpp-client.readthedocs.io/en/latest/

Source Code: https://github.com/gemini-hlsw/gpp-client

---

Python client and CLI for the GPP. Key features:

• Type‑safe GraphQL
  • Pydantic models from the GPP GraphQL schema, so every query, mutation, and input type is validated.
• Resource Managers
  • High‑level Manager classes (e.g. GPPClient.program, GPPClient.observation) with convenient get_by_id, get_all, create, update_by_id, delete_by_id, restore_by_id and more methods, no need to write raw GraphQL.
• Flexible payloads
  • Create or update via in‑memory Pydantic inputs or from_json files.
• gpp CLI
  • Full CRUD surface on the command line: gpp <resource> list|get|create|update|delete, with rich table output and JSON export options.

Requirements

• python>=3.10
• toml
• typer
• ariadne-codegen

Development Status

🚧 Alpha: the library is under heavy development. The public API and CLI flags may change between releases.

Installation

pip install gpp-client

Quickstart

from gpp_client import GPPClient

# Initialize with your GraphQL endpoint and credentials.
client = GPPClient(url="YOUR_URL", token="YOUR_TOKEN")

# List the first 5 program notes.
notes = await client.program_note.get_all(limit=5)
for note in notes["matches"]:
    print(f"{note['id']}: {note['title']}")

# Create a new note from a JSON file.
new_note = await client.program_note.create(
    from_json="path/to/program_note_payload.json",
    program_id="p-123"
)
print("Created:", new_note)

# Or create a note from the pydantic model.
from gpp_client.api.enums import Existence
from gpp_client.api.input_types import ProgramNotePropertiesInput

properties = ProgramNotePropertiesInput(
    title="Example",
    text="This is an example.",
    is_private=False,
    existence=Existence.PRESENT
)
another_note = await client.program_note.create(properties=properties, program_id="p-123")

print("Created another:", another_note)

As a CLI

# Get help.
gpp --help

# Get observation help.
gpp obs --help

# List observations.
gpp obs list --limit 3

# Get details for one.
gpp obs get o-123

# Create via JSON.
gpp obs create --from-json new_obs.json --program-id p-123

# Update by ID via JSON.
gpp obs update --observation-id o-123 --from-json updated_obs.json
