All Things Ubuntu Library

ATU Library (All Things Ubuntu Library) is a collection of libraries in Object Pascal for use with FreePascal and Lazarus IDE, that provide API dedicated to various versions of Ubuntu, including: - standard desktop Ubuntu - Ubuntu Mate ARM (ie. raspberry pi) - Ubuntu Touch/UBports Since most of resources available for Lazarus programmers are related to Windows OS, this library is aiming at addressing those interested in Linux programming with FPC and Lazarus, but tested with Ubuntu distributions. On Ubuntu Touch, you can install everything from the Terminal app or via ssh, either or will work. Just follow these steps: #download: $ wget https://sourceforge.net/projects/all-things-ubuntu-library/files/ATU_arm-linux.tar.gz #extract: $ tar -xf ATU_arm-linux.tar.gz #install ATU locally: $ ./ATU_arm-linux --install #you also recommended to install dependencies like this: $ sudo ./ATU_arm-linux --installdeps #if you're using Vivid this will also f

.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.
