I/O platform functions for the East programming language in Python.

Python equivalent of @elaraai/east-node-io - provides platform functions for S3 object storage and SQLite database operations.

Installation

pip install east-py-io

Quick Start

import asyncio
from east.runtime.compiler import compile_async
from east_py_io import python_io_platform

# Assuming you have East IR from the TypeScript compiler
# compiled_fn = compile_async(ir, python_io_platform)
# await compiled_fn()

Platform Functions

S3 Operations (s3_impl)

6 functions for AWS S3 and S3-compatible object storage (MinIO, Backblaze, etc.):

  • s3_put_object(config: S3Config, key: String, data: Blob) -> Null - Upload object (async)
  • s3_get_object(config: S3Config, key: String) -> Blob - Download object (async)
  • s3_head_object(config: S3Config, key: String) -> S3ObjectMetadata - Get metadata without downloading (async)
  • s3_delete_object(config: S3Config, key: String) -> Null - Delete object, idempotent (async)
  • s3_list_objects(config: S3Config, prefix: String, maxKeys: Integer) -> S3ListResult - List with pagination (async)
  • s3_presign_url(config: S3Config, key: String, expiresIn: Integer) -> String - Generate presigned URL (async)

S3Config structure:

{
  region: String,
  bucket: String,
  accessKeyId: Option<String>,
  secretAccessKey: Option<String>,
  endpoint: Option<String>  // For S3-compatible services
}

S3ObjectMetadata structure:

{
  key: String,
  size: Integer,
  lastModified: DateTime,
  contentType: Option<String>,
  etag: Option<String>
}

S3ListResult structure:

{
  objects: Array<S3ObjectMetadata>,
  isTruncated: Boolean,
  continuationToken: Option<String>
}

SQLite Database (sqlite_impl)

4 functions for SQLite database operations with connection pooling:

  • sqlite_connect(config: SqliteConfig) -> ConnectionHandle - Connect to database, returns handle (async)
  • sqlite_query(handle: ConnectionHandle, sql: String, params: Array<SqlParameter>) -> SqlResult - Execute parameterized query (async)
  • sqlite_close(handle: ConnectionHandle) -> Null - Close connection (async)
  • sqlite_close_all() -> Null - Close all connections, useful for cleanup (async)

SqliteConfig structure:

{
  path: String,
  readOnly: Option<Boolean>,
  memory: Option<Boolean>
}

SqlParameter variant:

String(String) | Integer(Integer) | Float(Float) | Boolean(Boolean) |
Null(Null) | Blob(Blob) | DateTime(DateTime)

SqlResult variant:

select({ rows: Array<Dict<String, SqlParameter>> }) |
insert({ rowsAffected: Integer, lastInsertId: Option<Integer> }) |
update({ rowsAffected: Integer }) |
delete({ rowsAffected: Integer })

Usage

Full Platform (Async)

from east_py_io import python_io_platform
from east.runtime.compiler import compile_async

# Use all I/O platform functions (all are async)
compiled_fn = compile_async(ir, python_io_platform)
await compiled_fn()

Individual Modules

from east_py_io import s3_impl, sqlite_impl

# Use specific platform function groups
platform = [*s3_impl, *sqlite_impl]
compiled_fn = compile_async(ir, platform)

# Or just one module
platform = [*sqlite_impl]
compiled_fn = compile_async(ir, platform)

Type Definitions

from east_py_io import (
    S3ConfigType,
    S3ObjectMetadataType,
    S3ListResultType,
    SqliteConfigType,
    SqlParameterType,
    SqlResultType,
)

# Use type definitions in your platform functions

Development

# First-time setup (installs dependencies)
make install

# Development workflow
make test          # Run test suite (17 tests)
make lint          # Run linter (ruff)
make lint-fix      # Auto-fix linting issues
make typecheck     # Type check with mypy
make check         # Run all checks (lint + typecheck + test)

# Other useful commands
make coverage      # Generate HTML coverage report
make clean         # Clean build artifacts

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
