AutoDoc Reader

This is a great freeware program to view any text file (autodocs, C-header and others) with database and search options. This is very useful to read the autodocs from the Software Development Kit. Developers documentation in autodoc format is often needed in everyday work. Getting familiar with a lot of files and searching tons of text for desired information is not an easy task. That's where the idea of writing a program that could ease using autodocs originated.

Features include:

• Possibility of creating a database of ours autodocs files,
• Fast and easy documents browsing,
• Possibility of independent loading of autodocs not included in a base,
• Search engine for functions, methods and parameters,
• Easy usage with mouse or keyboard.

The program can act as separate viewer or autodoc-viewing module for other software (e.g. DOpus or GED).

Emperor

Emperor is a very powerful software to write GUI-based programs. There are C/C++- source codes that are generated by Emperor. They can be easily translated by an external C/C++-Compiler. Developer wanted to make parameterizing of the Graphical User Interface (GUI) and its macro-elements as easy as possible. Following standard-GUI-elements are implemented:

• Screens
• Windows
• Reaction gadgets
• Menus
• Popup-menus
• Requests
• ASL-requests
• Locale-catalogs

Following NON-GUI-elements are implemented:

• Functionmacros
• Install-scripts
• ToolTypes
• Includes
• Libraries
• Declare variables
• InterConnection maps between gadgets
• Create list-arrays for gadgets

With Emperor you are generating a complete C/C++-source code, which only must be compiled by an external compiler. Aim of this program is to assure software developer to create their programs (its source code) by Emperor, because the making of software (opening of windows, file- and fontrequests, menus etc.) is often equal and must not longer copied by programmers from other source codes. Emperor decrees about one or more macros for every GUI-element. Like the menus: here you must, for creating the complete Project-menu (open, close, save, print etc.) and its translation, (in Locale-".catalog"-file) only select the corresponding entry in the list. This is also possible with requests e.g. by making a QuitRequest. These are called in the own source code as function "REQUESTNAME();". But the program should also be for Amigans, who never programmed before, and want an easy way in the programming of AmigaOS-GUIs.

Image Source: Hollywood webpage

Hollywood is a multimedia-oriented programming language that can be used to create graphical applications very easily. It was designed with the paradigm to make software creation as easy as possible in mind. Thus, Hollywood is suited for beginners and advanced users alike. Hollywood comes with an extensive function library (encompassing over 800 different commands) that simplifies the creation of games, presentations, and applications, to a great extent. Having been in development since 2002 it is a very mature and stable software package today.

One of the highlights of Hollywood is its inbuilt cross-compiler which can be used to deploy software on many different platforms without having to change a single line of the code. The cross-compiler can compile for all platforms from any platform Hollywood is running on. For instance, you can compile macOS application bundles using the Windows version of Hollywood. There is even an optional add-on that can convert Hollywood applets into stand-alone APKs for release on Android! Android development has never been so easy!

Hollywood is a light-weight, but still powerful programming language whose core is just about two megabytes in size and does not require any external components. Hence, it is ideal for creating programs which run right out of the box. In fact, Hollywood programs will run perfectly from an USB flash drive without any prior installation whatsoever.

Platform architectures currently supported include AmigaOS, Android, iOS, MacOS, Windows, Linux and more.

Lua / LOVE / tolua++

Image Source: Lua webpage

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description.

Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode with a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

LOVE is an awesome framework you can use to make 2D games in Lua. It's free, open-source, and works on Windows, Mac OS X, Linux and AmigaOS.

tolua++ is an extension of toLua, a tool to integrate C/C++ code with Lua. tolua++ includes new features oriented to c++, such as class templates.

tolua is a tool that greatly simplifies the integration of C/C++ code with Lua. Based on a "cleaned" header file, tolua automatically generates the binding code to access C/C++ features from Lua. Using Lua-5.0 API and metamethod facilities, the current version automatically maps C/C++ constants, external variables, functions, namespace, classes, and methods to Lua. It also provides facilities to create Lua modules.

MUIRexx

MUIRexx is a program which serves as an interface between ARexx and MagicUserInterface (MUI). MUIRexx does not provide complete access to all of the capabilities of MagicUserInterface (MUI), however, quite a lot of capability is implemented in MUIRexx such as notification, icon buttons, and application objects (objects that react to icons dropped on them), as well as many standard MUI objects. Complete graphical user interfaces as well as full applications can be developed using MUIRexx and ARexx macros. Additionally, it is also possible to dynamically change or add objects after the application has been created.

SDK Browser

Image Source: SDK Browser webpage

The SDK Browser provides any Amiga Programmer a quick reference tool into the live AmigaOS Software Development Kit installation on your Amiga, via a 100% graphical (GUI) based tool. It can help you find the format (prototype) for any AmigaOS4.x system call as well as lookup a specific structure reference, method, tag item, what-have-you, quicker than any other tool. Or, you can simply use it as a great way to wander through the AmigaOS4.x development documentation (AutoDocs, Includes, etc.) to learn more about how to program for this great machine and its powerful operating system. There is a great deal of (largely untapped) power available with the "standard" OS if you only know where to look.

Features include:

• Fully multitasking search bar with start/stop and pause/resume. File pattern filter added to search bar, and maintained separately for each search type. Interact with results as they are found, or continue to use all other parts of the SDK Browser as the search continues in the background. Search will continue even when hidden or iconified, and is controllable from the commodity exchange as well.
• History Bar. Quickly return to any of the last 20 items that have been viewed previously. Browse forward or back with the arrow buttons, or pull down and select a new position within the browser history. The history bar works like a combination of a web browser forward and back buttons and a rotating 20 item tabbed display. Giving you the flexibility to quickly work with the last 20 items that have been referenced already.
• Support for more than one interface(API) found within the same library. If the XML file for a given library contains more than one interface for accessing that library, then the SDK Browser will create a new browsable Library tree for each interface and name them with their respective interface name. This is also why the Interface name was added to each library entry under the Library list.
• Faster than ever before using newly optimized viewing routines and less disk access.
• Function calls under "Commands" or an open view of any "Library" now displays just the description of the function call within the AutoDoc instead of displaying the entire AutoDoc and attempting to search for the start of the description. This makes for a cleaner an easier to read display, while the entire AutoDoc file is still instantly available by selecting the Library name itself, or browsing the "AutoDocs" directly.
• Quick find ANY item in the active list just by typing the first few letters of its name.
• New "Includes" browsing. Live browse the system includes using the new embedded directory scanner.
• Convenient "Send To" menu for launching a helpful set of external viewers right from the SDK Browser. Quickly open source files into the editor of your choice, or open HTML files directly into your web browser of choice. You can also launch the currently selected file with "MultiView", "AmiPDF", or even "Unarc" those archives.
• Improved interface handles all Library, Commands, AutoDocs, and Includes browsing under the "SDK" clicktab, while also giving the user a "Project" tab and directory scan lister for browsing their own project source or any where you need to, quickly and easily from one tool.
• Extensive keyboard controls to enhance the existing "mouse-over" focused movement keys and "mouse-wheel" support.
• Programmable SDK and search paths.
• Programmable EDITOR and WEBBROWSER tooltypes for use by the "Send To" menu.

vbcc

Image Source: vbcc webpage

vbcc is a highly optimizing portable and retargetable ISO C compiler available for AmigaOS. It supports ISO C according to ISO/IEC 9899:1989 and a subset of the new standard ISO/IEC 9899:1999 (C99).

It is split into a target-independent and a target-dependent part, and provides complete abstraction of host- and target- arithmetic. Therefore, it fully supports cross-compiling for 8, 16, 32 and 64bit architectures. Embedded systems are supported by features like different pointer-sizes (e.g. differently sized function- and object-pointers or near- and far-pointers), ROM-able code, inline-assembly, bit-types, interrupt-handlers, section-attributes, stack-calculation and many others (depending on the backend). vbcc provides a large set of aggressive high-level optimizations as well as target-specific optimizations to produce faster or smaller code. Rather than restricting analysis and optimization to single functions or files, vbcc is able to optimize across functions and even modules.
