Thrift Delphi Software Library

. Delphi Lightweight, language-independent software stack for point-to-point RPC implementation. Thrift provides clean abstractions and implementations for data transport, data serialization, and application level processing. The code generation system takes a simple definition language as input and generates code across programming languages that uses the abstracted stack to build interoperable RPC clients and servers. Thrift makes it easy for programs written in different programming languages to share data and call remote procedures. With support for 28 programming languages, chances are Thrift supports the languages that you currently use.

BAScript

BAScript is a simple scripting engine written in Object Pascal you can use to add scripting to your Delphi, Lazarus or Free Pascal applications ("host program") to extend their functionality without the need of recompiling them. The virtual machine defines its own language, called the BAScript language. It is a low-level language, somewhat similar to the Assembler language, which is not intended to be easy to program but easy to execute. So it is recommendable to use other higher level languages and translate them into BAScript language. Package includes two compilers that translates from a higher-level language to the BAScript language. You should note that BAScript is intended to be lightweight, so it has not mechanisms to handle complex data structures or large amounts of data or code. On the other hand, it has less need for memory and resources than other scripting interpreters. If you need more power you may try PascalScript.

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.
