Add your description here

TSQL

A Python Environment Database Module Generator

Installation

to install using pip:

$ pip install tsql-yaboiteedoh

Usage

the bash command:

$ tsql

Runs the application in the current directory, allowing you to search it for valid configuration files or generate a new database where you are

To get the most out of that I have it installed into a toolbox .venv, and have added this function to my ~/.bashrc script:

sql() {
    (
        source '/home/teedoh/devkit/.venv/bin/activate'
        tsql
    )
}

Saving the configuration saves to the current directory under (database name).tsql Default behavior is to not override previous saves, to enable easier version control

Exporting the configuration folder dumps a python module named after the database into the current directory, which you can reach with

from {database name} import Database

once instantiated, you can reach into the database with the associated functions on the table objects

db = Database()
with db:
    table_entries = db.{table name}.read_all()

Functionality

0.1.9

• support for datatypes
  • TEXT
  • INT
  • BOOL
• Groups
  • search multiple columns for the same value
• Filters
  • return based on a combination of column and group values
• parameters
  • NOT NULL
  • PRIMARY KEY
  • AUTOINCREMENT
• Column Types
  • functions with dataclass object returns for unique column values
  • functions with list of dataclass object returns for shared column values
  • any column not labeled 'returns' is considered passive
    • these will exist on the dataclass object but not have an associated query function
• Column references
  • these will update dynamically as you alter your table config

0.1.10

• export module alterations
  • to use the database object via context manager
  • to remove create tables on database object init
    • instead use

database.init_tables()

0.2.0

• expanded data types and parameters
  • data types
    • TEXT
    • INTEGER
    • REAL
    • BLOB
  • parameters
    • PRIMARY KEY
    • AUTOINCREMENT
    • NOT NULL
    • CHECK
      • Saves expressions as entered
    • DEFAULT
      • Including support for
        • CURRENT_TIME
        • CURRENT_DATE
        • CURRENT_TIMESTAMP
    • COLLATE (on TEXT columns)
• config validation
  • enforces unique table/column/filter/group names in their proper scopes
  • enforces non-empty groups and filters
  • More to come as cases emerge

0.3.0

• Hidden columns which will not appear on the dataclass object
  • Table dataclasses no longer use dataclass module
  • reading and updating values on hidden classes require rowid to query

0.3.1

• Dataclasses now have a config property which prints a simple dictionary
  • contains row ids for reference tables
  • setter allows for quick updating of all columns on the object
• Dataclasses now have a view function which prints a complex dictionary
  • row id columns for reference tables are now dataclass.config dictionaries
  • this is recursive
• Filesystem changes
  • streamlined the export filesystem
    • main module contains everything but the table class definitions
• Module should now be able to find the included database no matter where it gets run from

0.4.0

• Finalized Join functionality through the view(db) function standard on each dataclass object

0.5.0 (planned)

• Built in version control system
• data migration tools

1.0.0 (planned)

• Interface overhaul
