CodeSnip

CodeSnip is an open source code bank for storing and viewing code snippets. It not only manages, displays and manipulates your own code snippets but it can also incorporate snippets downloaded from the online DelphiDabbler Code Snippets Database. > CodeSnip's source code is now developed over on GitHub: https://github.com/delphidabbler/codesnip Designed with Pascal code in mind, CodeSnip enables Delphi or Free Pascal code snippets to be test-compiled with any installed Delphi or Free Pascal compiler and results to be reported. Use this feature to validate the syntax of code without switching to your compiler. Compilable Pascal units containing selected snippets can be generated. Code in other languages can be stored in CodeSnip although the source file generation and compiler checking features will not be available. Compilable Pascal units of selected snippets can be generated. Selected snippets can also be exported and shared with other CodeSnip users.

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.
