Tennis-Club-Booking-System

The Tennis Club Booking System is a tool designed to help administrate and manage tennis club data, including bookings and members. The system allows you to add, edit and delete both bookings and members. It offers both a list view and a calendar view for viewing bookings stored in the system, and a list view for viewing members. The system checks input when adding data to the system so that any bookings/members added follow the club’s schedule/rules. When viewing bookings/members to user can filter to list to specified parameters allowing easy searching of the system. The system also creates automated backups of the database every week to keep the database safe, and also requiring an admin login to view members’ personal details.

timmy

Timmy is a Pascal unit for creating chat bots. It provides the TTimmy object, which is a data type that you can assign your variables to to make bots. Once that is done, you can start adding keywords for messages, and get the bot answers to the end user's messages. It's easy to create a bot with Timmy. The unit also provides some other string-related functions, alongside with TStrArray type, which is actually array of string (but it's shorter to call it TStrArray, isn't it?). Timmy is released under GNU LGPL v3. That means it respects your freedom and you can use it with your program whether if your program is free software or proprietary software.

OAuth2Client

An RFC 6749 OAuth2 Client implemented as a Lazarus Package. The client is intended to be fully featured and supports the following grant types: Authorization Code Grant Implicit Grant Resource Owner Password Credentials Grant Client Credentials Grant. Attention has also been paid to extensibility. The client also provides: A means of implementing an Extension Grant, including new grant types. Support for new token types Support for New Endpoint Parameters, and Support for additional error codes. This OAuth2 Client uses an external User Agent - the System Web Browser - and incorporates in internal http server for handling redirect responses from an Authorization Server. The package uses the Indy Component library for both an http/https client and an http server. When the https protocol is used the OpenSSL library must also be installed and available for use. Multithreading support is required for Authorization Code and Implicit Grants. The package is written in Object Pascal and is made available under the Lesser GPL. The package requires the Indy package for http/https protocol support. It has been configured for use with the MWA Software IndySecOpenSSL package and the Indy Component Library. A separate branch (Indy106Compat) is also available. This will work with the Indy Component library on its own. However, you will be limited to using the unsupported OpenSSL 1.0.2 library (current is OpenSSL 3.x) and TLS 1.2. For installation instructions please refer to the User Guide.
