.Net Native Library for Lazarus

The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for Lazarus/Pascal programming language to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.

MPL Bytecode Compiler

NEWS: The MPL language is now completely defined. No more language changes are to be made. The compiler is complete and should be easy to translate to other languages if you so choose. MPL is a small, simple language based on BCPL, B, C and Jesusonic. The compiler and interpreter are written in portable Pascal. I have successfully compiled MPL for CP/M, DOS, Windows, Atari ST, Amiga and the Tandy Colour Computer. MPL is designed to be tiny in every way, while implementing all the important features of BCPL & B. The result is a compiler written in a high level language (PASCAL) which compiles to under 16K (CP/M). The symbol table, language syntax, and bytecode are all optimized for size. I will write a MPL Reference Manual in time. Contact myself if you want to help get that written.

.Net Native Interface Library

The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.
