deisa-project Spack packages

A Spack package repository for deisa-project software.

Currently provides:

Spack package	Upstream project
py-deisa-ray	deisa-project/deisa-ray — In Situ Analytics with Ray backend

This repository exists so that the py-deisa-ray recipe can be updated independently of the upstream spack/spack-packages repository. When this repo is registered before builtin, Spack uses the recipe here instead, so you get new releases as soon as this repo is updated — you don't have to wait for the upstream PR to be merged.

Requirements

• Spack v1.0+ (this repo uses package API v2).

Register the repository

Option A — from a local clone (recommended):

git clone https://github.com/deisa-project/spack.git
spack repo add "$PWD/spack/spack_repo/deisa"

Option B — let Spack clone and manage it (uses spack-repo-index.yaml):

spack repo add https://github.com/deisa-project/spack.git

Option C — declare it in an environment (spack.yaml):

spack:
  repos:
    deisa: /path/to/spack/spack_repo/deisa
  specs:
    - py-deisa-ray

This repository is private, so cloning over HTTPS requires a token, or use SSH: git clone git@github.com:deisa-project/spack.git.

Verify it is picked up:

spack repo list          # 'deisa' should be listed (and appear before 'builtin')
spack info py-deisa-ray

Install

spack install py-deisa-ray                 # latest version
spack install py-deisa-ray@0.1.9           # a specific version
spack install py-deisa-ray@0.1.9 +example  # with the getting-started example deps (matplotlib)

The +example variant installs py-matplotlib, which is only needed to run the getting-started example.

Updating the recipe

1. Edit spack_repo/deisa/packages/py_deisa_ray/package.py.
2. Commit and push.
3. Consumers update and re-install:

# local clone:
git pull

# or, if Spack manages the clone:
spack repo update deisa

spack install py-deisa-ray

Adding a new version

Always generate the version(...) line with Spack so the checksum is correct:

spack checksum py-deisa-ray <version>

Then paste the printed line into package.py (newest version first, and don't remove older versions).

Notes

• When registered, this repo overrides the py-deisa-ray recipe shipped in spack-packages (repo order matters: this one must come first).
• The recipe files derive from spack/spack-packages (licensed Apache-2.0 OR MIT) and keep their original license headers.
