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

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.

.Net Runtime Library for Delphi

The .Net Runtime Library for Delphi (CNClrLibrary) is the best library to work with .Net framework and .Net libraries from Delphi. It is designed to provide a way to interact with applications written in anyone of the .Net languages (such as C#, Visual Basic.Net, Delphi.Net, JScript.Net, etc) from Delphi. CNClrLibrary allows Delphi to use .Net libraries without the need for registry entries, COM registrations, or changes to the .NET libraries. Competitive Advantages: - No extra dll is required when deployed. - No COM registration of .Net Libraries is required when deployed. - There are tools to generate your .Net Libraries into Delphi pas files. - Allows Delphi to consume .Net libraries as if they were native code. - Full access to .Net Framework Class Library. - Easy to use. CNClrLibrary can do so much: - Access .Net Framework Class Library. - Access Third Party .Net Libraries. - Access Your .Net Libraries. - etc Latest Version: 6.0.7.0

.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.
