Source texts of compilers
    Most stuff listed here is written by rare enthusiasts for educational purposes or even for amusement. Due to numerous causes (laziness or lack of spare time, possibly) most of these projects were abandoned half done or even at the very beginning. Thatís why many of them lack functionality and capabilities. Nevertheless, they are suitable as good examples for education.
    Apropos some particularities. The majority of developers had solved the output format problem enough easy; not wanting to deal with object and executable filesí specifications, they had changed the output to simple and plain assembler text listing. Due to that youíll need any other assembler and, possibly, a linker. To my mind itís the most suitable solution, cause one can do with this listing whatever he wants.
    Almost all archives contain the compiled executables (if the contrary is not affirmed).

    bas2nasm.zip (~17kb) QuickBasic to Nasm compatible compiler v1.13 (c) 2003 by Nicholas Dark
    A tiny toy-compiler from QuickBasic compatible language to Nasm opcodes. The capabilities are not impressive. An example program is applied. No .exe compiled.

    basic.zip (~81kb) Basic compiler for MenuetOS (c) by Jarek Pelczar
    As you can judge by name, itís a Basic compiler. Actually, this one is included to distribution package of alternative 32-bit operating system named Menuet, but let it be here for safety. It produces 32-bit machine code for protected addressing mode (of Menuet, not Dos), but one can make even a .com executable. Also remark: while evaluating the mathematical expression this program emits greatly unoptimized asm instructions, identically to the ďstudentĒ compilers do (look below).

    basmv650.zip (~797kb) The BASIC to 286 Assembly Language Translator v6.50 (c) 1998 by Kevin Diggins.
    Another ďBasicĒ clone. This zip is one of a multitude findable in Internet and is thought to be the last version. An IDE with the help files and an Arrowsoft assembler are added. Also one can find a bunch of examples. Just as Sphinx C--, Basm286 evaluates mathematical expressions left to right, regardless of operation precedence.

    bxbsrc.zip (~120kb) Blunt Axe Basic v1.052a (c) 2001-2004 by Sarbayo
    This is a QuickBasic/RapidQ subset. Yet Bxbasm can compile Win32 console-mode executables only. Note that Bxbasm in its assembler output uses many inner Masm32 macros such as invoke, .if-.else-.endif etc. The full package (with Masm32 Ė about 2.5Mb) can be downloaded from the home page.

    newbasic.zip (~138kb) Free QuickBasic compatible compiler (c) 1998 by Marcel Smolenaars
    Itís a very cute implementation of Basic-like compiler. The syntax is close to that of QuickBasic. Supported: subroutines/functions, local/global data, whole types (arrays partially), almost all program flow constructs. But it lacks standard libraries and such keywords as PRINT, DRAW canít be used. Though this compiler handles complex expressions like ďn=(x*(20-b/a)-function1(a*b,x*(z-y),b))Ē with all priorities and emits enough optimized code (without that spaghetti pushs and pops!) The output format is plain asm listing.

    sbasic20.zip (~60kb) SBasic 2.0 (C) 1989-91 DMV Widuch GmbH & Co.KG; Autor: Wolfgang Lorenz (ASCII-/LABEL-BASIC-Preprocessor: Peter Knappe)
    Have you ever seen a compiler written in GW-Basic? You think itís impossible? Turn on your imagination! Not working? Then take a look at this stuff and let it be your everlasting nightmare!.. This compiler accepts an input language similar to GW-Basic, moreover itís written in it itself! A little IDE is also included with its own sources (of course in GW-Basic).

    ubasic031.zip (~440kb) UltraBasic v 0.31a (c) 2000 by Gabriel Fernandez, 2004 by Angelo Rosina
    The successor of GaBasic. It is compatible with QuickBasic as closely as itís possible in protected mode: all math expression are evaluated according to operation priorities. The support for Win32 console executables is added! (Probably the creation of windowed exeís is possible). The libraries are tuned greatly, the sources of them are included. As can be guessed, the new author is busy expanding the capabilities of the compiler, the latest news are posted on his homepage.

    bcc.zip (~206kb) BCC (Ů) 1992 by Bruce Evans
    Unfortunately, thereís no any complete documentation, so nothing can be said apropos. Itís clear only that it is a C-like compiler which can emit an asm listing for Motorola 6809 and Intel 8086/386 processors (16 and 32 bit). There are several examples attached. Youíll need also an assembler as.zip (~125kb) and a linker ld.zip (~26kb) (the latter isnít compiled though). The full sources with MS-DOS binaries can be found on home page.

    A C-like language called with the adequate shortness as ďBĒ. Possibly, due to the fact that itís only a subset of the previous. It can emit 32-bit code for WDosX extender though.

    Minimalistic C-like compiler created by some Pakistani student as his project on a compiler construction course. The outputted code is non optimized greatly. Some examples and a detailed description of intrinsic routines are included. One remark: use MSVC++ 6.0 only to recompile (since Watcom and Mingw did not succeed).

    As the name say, this compiler produces asm listings for Motorola 68000 and Intel 386 (32-bit code) processors. No compiled .exe. It seems that this stuff is written for SunOS. But Iím not completely sure. If someone figure out, let me know!

    draak5.zip (~71kb) Draak the 16-bit multi-language compiler (c) 2000 by Jon Gentle
    Itís a multi-language compiler, the input language and code generation of which can be defined in external .def scripts. The given version is tuned to compile C-like language. The capabilities are not wide though. This project has been revived on Sourceforge.net. The last version 0.82 is pretty more handy, the full description is lacking though.

    When Peter Cellik had retired, heíd presented to public the sources of his unforgettable creation Ė Sphinx C--. This is the version 2.0, the last, as Peter (and many of us) thought. Yeah, piece of cake. This project was resurrected by Michael Shecker (donít let this name confuse you, heís Russian!) Wanna see how far heíd pulled it? Take this outdated stuff then go there: http://c--sphinx.narod.ru and compare. The compiler is written in C, for successful recompilation youíll need Microsoft C v6.0. The sources of the Workbench are also included (.pas for Borland Pascal). For those who doesnít know one particularity, I remind: Sphinx evaluates all expressions left to right, regardless of operation precedence.

The Context programming language looks quite like Modula with some C elements. A little assembler (written in Context) is included.

    Another try to write a 32-bit Pascal, greatly worthy of attention. Some of the advantages: support of floating-point math, compatibility with Borland Pascal both in syntax and runtime library, code optimization for Pentium processors, ability to create Dos32, Wdosx and Win32 executables.

    "Student" compilers are grouped together, cause they have been created as a part of university studies and the aim of their authors was to pass the test successfully, but not to create an effective compiler.
