dpe-dev

Tool-authoring CLI for the DPE data processing engine. Scaffold, build, and test custom tools in Rust, Python, or TypeScript / Bun.

Install

npm install -g dpe-dev

Auto-resolves the right native binary for your OS + CPU.

Or via Docker:

docker pull ghcr.io/combycode/dpe-dev:latest      # full toolchain (rustc, bun, python, claude CLI)

Quick start

# Scaffold a tool from one of three runtime templates
dpe-dev scaffold --name my-tool --runtime rust   --out ./my-tool --description "what it does"
dpe-dev scaffold --name my-tool --runtime bun    --out ./my-tool --description "what it does"
dpe-dev scaffold --name my-tool --runtime python --out ./my-tool --description "what it does"

cd my-tool
dpe-dev build .    # cargo build --release / bun install / pip install -e .
dpe-dev test  .    # cargo test / bun test / pytest

For pipeline-context stage testing (envelopes through a real variant + cache + env), use dpe test <pipeline>:<variant>:<stage>:<case> from the runner CLI — see dpe test --help.

Commands

| Command | Purpose | |---|---| | dpe-dev scaffold | create a new tool from a runtime template | | dpe-dev build <dir> | runtime-aware build (cargo / bun install / pip install -e .) | | dpe-dev test <dir> | runtime-aware test (cargo test / bun test / pytest) | | dpe-dev check <dir> | static checks (meta.json valid, spec.yaml parses, entry exists) | | dpe-dev setup [path] | bootstrap a dev workspace with the embedded skill pack and fixtures |
