east-py-cli

License: BSL 1.1

Command-line interface for running East IR programs with Python platform functions.

Installation

uv add east-py-cli

# Platform packages are installed separately as needed
uv add east-py-std          # console, crypto, fetch, fs, path, random, time
uv add east-py-io           # s3, sqlite, postgres, mysql, redis, mongodb, xlsx, xml, gzip, tar, zip, ftp, sftp
uv add east-py-datascience  # sklearn, scipy, xgboost, lightgbm, ngboost, torch, shap, optuna, simanneal, mads

Usage

Running Programs

# Run with platform packages
east-py run program.beast2 -p east-py-std

# Run with multiple platforms
east-py run program.json -p east-py-std -p east-py-io -p east-py-datascience

# With input and output files
east-py run program.beast2 \
  -p east-py-std \
  --input data.beast2 \
  --input config.json \
  --output result.beast2

# Verbose output
east-py run program.beast2 -p east-py-std -v

Version and Platform Info

# Show CLI version
east-py version

# Show version with platform info
east-py version -p east-py-std -p east-py-io

Example output:

east-py-cli 0.1.0
east-py 0.1.0

Platforms:
  east-py-std 0.1.0 (47 platform functions)
  east-py-io 0.1.0 (59 platform functions)

File Formats

IR and data files are auto-detected by extension:

Extension Format
.beast2, .beast Binary East v2
.east East text format
.json JSON

Creating Platform Packages

Platform packages must export a platform attribute containing a list of platform functions:

# my_platform/__init__.py
from east.runtime.platform import platform_function

@platform_function("my_func", inputs=[StringType], output=IntegerType)
def my_func_impl(s):
    return len(s)

platform = [my_func_impl]

Claude Code plugin

The East ecosystem also ships a Claude Code plugin — East language skills, example search, and preemptive diagnostics for East code — installed separately from the elaraai marketplace:

# Inside Claude Code
/plugin marketplace add elaraai/east-workspace
/plugin install east@elaraai

# From a terminal
claude plugin marketplace add elaraai/east-workspace
claude plugin install east@elaraai

Ecosystem

  • East: Statically typed, expression-based language with serializable IR. Run portable logic across TypeScript, Python, C, and other runtimes.

    • @elaraai/east: Core language SDK with type system, expressions, and reference JS compiler

  • East Node: Node.js platform functions for I/O, databases, and system operations.

  • East C: C11 native runtime for executing East IR. Distributed via npm (launcher + per-platform optional dependencies) and as tarballs on each GitHub Release.

    • @elaraai/east-c-cli: npm launcher — installs the matching native binary as an optional dependency
    • east-c: Core runtime — type system, IR interpreter, builtins, serialization (Beast2, JSON, CSV, East text)
    • east-c-std: Console, FileSystem, Fetch, Crypto, Time, Path, Random
    • east-c-cli: CLI for running East IR programs natively

  • East Python: Python runtime, standard platform, I/O, and data-science platform functions. Published to PyPI.

    • east-py: Core Python runtime — type system, IR compiler, 212+ builtins, Cython-accelerated hot paths
    • east-py-std: Console, FileSystem, Fetch, Crypto, Time, Path, Random
    • east-py-io: SQLite, PostgreSQL, MySQL, MongoDB, Redis, S3, FTP, SFTP, XLSX, XML, compression
    • east-py-cli: CLI for running East IR programs in Python
    • east-py-datascience (PyPI) + @elaraai/east-py-datascience (npm): Optimization (MADS, Optuna, ALNS, GoogleOR), ML (XGBoost, LightGBM, NGBoost, PyTorch, Lightning, GP), Bayesian inference (PyMC), explainability (SHAP), conformal prediction (MAPIE)

  • East UI: Typed UI component definitions and React renderer, plus VS Code preview.

  • e3 — East Execution Engine: Durable execution engine for running East pipelines at scale. Git-like content-addressable storage, automatic memoization, reactive dataflow, real-time monitoring.
