PureBasic

PureBasic is a commercially distributed procedural computer programming language and integrated development environment based on BASIC and developed by Fantaisie Software for Windows, Linux, macOS and Raspberry Pi. An Amiga version is available, although it has been discontinued and some parts of it are released as open-source. The first public release of PureBasic for Windows was on 17 December 2000. It has been continually updated ever since. PureBasic has a "lifetime license model". As cited on the website, the first PureBasic user (who registered in 1998) still has free access to new updates and this is not going to change. PureBasic compiles directly to IA-32, x86-64, arm32 and arm64, PowerPC or 680x0 instruction sets, generating small standalone executables and DLLs which need no runtime libraries beyond the standard system libraries. Programs developed without using the platform-specific application programming interfaces (APIs) can be built easily from the same source file with little or no modification. PureBasic supports inline assembly, allowing the developer to include FASM assembler commands within PureBasic source code, while using the variables declared in PureBasic source code, enabling experienced programmers to improve the speed of speed-critical sections of code. PureBasic supports and has integrated the OGRE 3D Environment.…

PureBasic supports and has integrated the OGRE 3D Environment. Other 3D environments such as the Irrlicht Engine are unofficially supported. Since version 6.00 (June 2022), in addition to compilation using ASM, PureBasic offers compilation with a C backend. This enables access to new platforms (e.g. Raspberry) and should make it easier to add new libraries in the future. MessageRequester("Message Box", "Hello World") And the following variant of the same code, which instead uses an inline Windows API call with no need for declarations or other external references, will create an even smaller 2.0 KiB (2,048 bytes) standalone x86 executable for Windows. MessageBox_(0, "Hello World", "Message Box", 0) The following is a console version of the Hello World example. OpenConsole() ; Open a console window. Print("Hello, World!") Delay(5000) ; Pause for 5 seconds Procedure bubbleSort(Array a(1)) Protected i, itemCount, hasChanged itemCount = ArraySize(a()) Repeat hasChanged = #False itemCount - 1 For i = 0 To itemCount If a(i) > a(i + 1) Swap a(i), a(i + 1) hasChanged = #True EndIf Next Until hasChanged = #False EndProcedure Below is a sample program that displays a sizeable text editor with two menu items. Create Window: OpenWindow(0, #PB_Ignore, #PB_Ignore, 800, 600, "Simple Text Editor", #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget) Add 2 menus: CreateMenu(0, WindowID(0)) MenuItem(1, "&OK") MenuItem(2, "&Cancel") Add Editor: EditorGadget(0, 0, 0, 0, 0) SetGadgetFont(0, LoadFont(0, "Courier New", 10)) Process window messages until closed: Repeat Select WaitWindowEvent() Case #PB_Event_Menu Select EventMenu() Case 1: MessageRequester("OK clicked directly or with '&' mnemonic.", GetGadgetText(0)) Case 2: Break EndSelect Case #PB_Event_SizeWindow: ResizeGadget(0, 0, 0, WindowWidth(0, #PB_Window_InnerCoordinate), WindowHeight(0, #PB_Window_InnerCoordinate)) Case #PB_Event_CloseWindow: Break EndSelect ForEver In this example program the string "OK clicked or with '&' mnemonic" quotes & with single-quotes. To use double-quotes instead the message string could be coded "OK clicked or with " + #DQuote$ + "&" #DQuote$ + " mnemonic" . The double-quote character could also be represented as Chr(34) . PureBasic does not support string interpolation like some other programming languages. Structure type_name field_name.type ; Single field. Perhaps the structures attachment. field_name[count].type ; Static arrays. ; ... ; Optional construction StructureUnion .. EndStructureUnion allows you ; to combine multiple fields into one area of memory ; that is sometimes required for the conversion types. StructureUnion type_name.type ; ... EndStructureUnion EndStructure Variables can be single (actually, standard variables), dynamic array (declared using the , a linked list ( ), an associative array (in new versions of language) ( ) This book is now freely downloadable === General references===
