Quick Start

from eftoolkit.sql import DuckDB
from eftoolkit.s3 import S3FileSystem
from eftoolkit.gsheets import Spreadsheet

# DuckDB with in-memory database
db = DuckDB()
db.create_table('users', "SELECT 1 as id, 'Alice' as name")
df = db.get_table('users')

# S3 operations (requires credentials)
s3 = S3FileSystem(
    access_key_id='...',
    secret_access_key='...',
    region='us-east-1',
)
s3.write_df_to_parquet(df, 's3://my-bucket/data/output.parquet')

# Google Sheets (requires service account credentials)
ss = Spreadsheet(credentials={...}, spreadsheet_name='My Sheet')
with ss.worksheet('Sheet1') as ws:
    ws.write_dataframe(df)
    ws.format_range('A1:B1', {'textFormat': {'bold': True}})
    # flush() called automatically on exit

# Google Sheets local preview (no credentials needed!)
ss = Spreadsheet(local_preview=True, spreadsheet_name='Preview')
ws = ss.worksheet('Sheet1')
ws.write_dataframe(df)
ws.flush()
ws.open_preview()  # Opens HTML in browser

Releasing (Maintainers Only)

Releases are automated via the release script. You must be on the main branch with no uncommitted changes:

./scripts/release.sh patch  # 0.1.0 -> 0.1.1
./scripts/release.sh minor  # 0.1.0 -> 0.2.0
./scripts/release.sh major  # 0.1.0 -> 1.0.0

This runs all checks, auto-bumps the version, generates release notes, and triggers the PyPI publish workflow.
