development environment ide liberty basic paradigm event driven procedural designed by carl gundel developer shoptalk systems first appeared 1992 34 years ago 1992 stable release 4 5 1 may 31 2017 9 years ago 2017 05 31 typing discipline dynamic weak os microsoft windows linux in unreleased liberty basic 5 license proprietary filename extensions bas fr3 website libertybasic com major implementations run basic glbcc influenced by quickbasic influenced just basic leopard the liberty basic v4 03 ide system liberty basic lb is a commercial computer programming language and integrated development environment ide it has an interpreter developed in smalltalk which recognizes its own dialect of the basic programming language it runs on 16 and 32 bit windows and os 2 background edit liberty basic was written by carl gunner gundel and published in its first release by his company shoptalk systems in 1991 it has progressed steadily since then the last published update update to the software version 4 5 1 was in june 2018 1 though liberty basic has its share of limitations in its design for advanced programming it provides an introductory integrated development environment ide for moderate to advanced users of windows and os 2 dynamic link libraries dlls are available in its current version it runs only on microsoft windows and under wine on linux alpha testing of liberty basic v5 0 is underway with versions that run on microsoft windows mac os x linux and on the raspberry pi as well liberty basic does not compile to native code instead it compiles the code written in the ide to an encrypted file with the extension tkn this file is then executed by an exe file that carries the same file name although this may change with the release of version 5 features edit liberty basic v4 03 running on linux with wine a visual development tool called freeform written in liberty basic and greatly extended by the liberty basic community over the years source level debugger calling of dlls and application programming interfaces apis color graphics capability can create games with sprite animation sound music and joystick control an add on package called assist with many new features such as a code formatter source code versioning a performance profiler an easy to use code difference browser and an improved package and deployment system distinguishing features edit liberty basic allows for procedural programming using a default main window that displays formatted text and accepts user input it also supports event driven programming based on a graphical user interface using several types of windows that may contain the standard controls such as buttons menus textboxes etc a central idea in creating liberty basic was to model the handling of windows after the syntax for file handling for example from the liberty basic help file the open command opens communication with a device which can be a disk file a window a dynamic link library or a serial communications port open device for purpose as handle len n once a device is open data and also commands to control that device can be printed to it for each type of device there is a set of commands which can be sent to it in this way in the more recent versions of lb the word print may be dropped from the print statement making the syntax even simpler simplicity has been at the heart of liberty basic from the beginning this makes it easier to learn but at some cost perhaps in limiting functionality only two data types are supported in lb v4 03 numeric and string no type declarations are required any variable with a sign at the end of its name is a string variable otherwise it is numeric the plan for lb v5 is to support other types and user defined types as well as these for the purpose of making calls to an api or third party dlls there is a struct and the additional types necessary for the dll the only other data structure supported is the array arrays of one or two dimensions are supported lb v5 may support arrays of user defined types notable programs written in liberty basic edit freeform a gui editor for creating gui formats citation needed example code edit here are some examples of the language hello world program print hello world end program to display a pop up message box with the words hello world on it nomainwin notice hello world end nomainwin notice example program chr 13 hello world end program to display an input box nomainwin prompt enter your name response notice response chr 13 response end running another application nomainwin run notepad exe end printing multiplication table of 5 on form multi for i 1 to 15 res 5 i print res next i end alternative implementations edit the gnu liberty basic compiler collection glbcc by anthony liguori is a set of tools to compile liberty basic programs runs on windows and linux systems but the project has not been updated since 2001 in 2012 an alternative windows implementation of liberty basic lb booster lbb became available although substantially compatible with the liberty basic 4 language syntax lbb was developed entirely independently by richard russell and is written in bbc basic lbb offers typically increased execution speed smaller self contained executables and some additional capabilities however lbb is not 100 compatible with lb4 and while many programs will run without modification some may need to be adapted or may even be unsuitable for running under lbb liberty basic does not provide for data declarations instead any new data name is treated as a new declaration some regard this as a benefit others see it as a debugging issue for imperfect typers in 2019 peter j d matthews devised a method for adding declarations and checking for undeclared data without changing the code seen by the lb interpreter in 2023 this system was ported to github in public repository lbprepass for anyone to use this repository also contains program documentation the program is written in liberty basic 4 5 1 and is intended to analyse 4 5 1 code references edit liberty basic news www libertybasic com retrieved january 25 2019 external links edit www libertybasic com
