    .Net Native Library for Lazarus

    The best library to work with .Net Assemblies in Pascal.

    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.

    BAScript

    Scripting engine for Pascal compilers.

    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 a BriefC compiler that translates from C-like 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.

    PasJas

    Pascal wrapper for JPeg2000 Jasper library

    This wrapper is bringing Jasper library to Pascal (Delphi). The JasPer Project Home Page: http://www.ece.uvic.ca/~frodo/jasper/ Support included for jp2(+ j2k, jpc), mif, pnm, ras, pgx formats; bmp and jpeg are excluded, usually included in Pascal (Delphi). All formats can be individually selected using specific defines. It supports irregular geometries and YCbCr on read. Imported jasper structures are valid for jasper-1.900.1 . It is currently compilable with Delphi XE5 but with a few changes should be easily adapted to other versions or FreePascal. Included object files are from jasper-1.900.1, precompiled with Borland C++ Compiler 5.5 (free). The jasper library is compiled WITHOUT any modification using the included bat file.
