libopenschichtplaner5 1.2.0

Read and write the original Schichtplaner5 FoxPro .DBF database files, plus the SQLite/PostgreSQL ORM and sync layer used by OpenSchichtplaner5.

libopenschichtplaner5

The core library behind OpenSchichtplaner5 — a pip-installable package that reads and writes the original Schichtplaner5 FoxPro/dBASE .DBF database files, so an open replacement can run on the exact same data as the proprietary Windows tool, with no migration.

Import name: the distribution is libopenschichtplaner5, but the importable package keeps its historical name sp5lib (like pip install PyYAML → import yaml). This keeps OpenSchichtplaner5's imports unchanged after the extraction.

What's inside

Module	Purpose
sp5lib.dbf_reader	Pure-Python DBF reader (UTF-16-LE detection, date parsing, field decode)
sp5lib.dbf_writer	Safe DBF writer — exclusive flock, TOCTOU-safe record count, rollback, EOF marker preservation
sp5lib.database	High-level SP5Database facade over the DBF tables (employees, shifts, schedule, absences, auth, 2FA …)
sp5lib.db_factory / sqlite_adapter / pg_database	Optional SQLite / PostgreSQL backends
sp5lib.orm	SQLAlchemy models (models.py SQLite, models_pg.py Postgres), repository, sync
sp5lib.auto_migrate	Alembic-based automatic migrations
sp5lib.email_service	SMTP notification emails (HTML-escaped templates)
sp5lib.color_utils	FoxPro BGR ↔ hex/RGB color helpers

Installation

pip install "libopenschichtplaner5 @ git+https://github.com/mschabhuettl/libopenschichtplaner5.git"
# with the optional PostgreSQL backend:
pip install "libopenschichtplaner5[postgres] @ git+https://github.com/mschabhuettl/libopenschichtplaner5.git"

Usage

from sp5lib.database import SP5Database

db = SP5Database("/path/to/SP5/Daten")        # directory of .DBF files
for emp in db.get_employees():
    print(emp["ID"], emp["NAME"], emp["FIRSTNAME"])

Low-level DBF access:

from sp5lib.dbf_reader import read_dbf
from sp5lib.dbf_writer import append_record, get_table_fields

rows   = read_dbf("/path/to/SP5/Daten/5EMPL.DBF")
fields = get_table_fields("/path/to/SP5/Daten/5EMPL.DBF")
append_record("/path/to/SP5/Daten/5NOTE.DBF", fields, {"ID": 1, "TEXT": "hello"})

Dependencies

Runtime: SQLAlchemy, alembic, bcrypt, pyotp, packaging. Optional: psycopg2-binary (via the postgres extra) for the PostgreSQL backend.
