Macintosh Programmer's Workshop or MPW, is a software development environment for the Classic Mac OSoperating system, written by Apple Computer. For Macintosh developers, it was one of the primary tools for building applications for System 7.x and Mac OS 8.x and 9.x. Initially MPW was available for purchase as part of Apple's professional developers program, but Apple made it a free download after it was superseded by CodeWarrior. On Mac OS X it was replaced by the Project BuilderIDE, which eventually became Xcode.
Design[edit]
MPW provided a command line environment and tools, including 68k and PowerPC assemblers as well as Pascal, C and C++compilers. The shell environment is somewhat similar to Unix shells in design, but is designed around the Macintosh's character set and GUI, replacing the usual terminal environment with a 'worksheet' interface, allowing the user to select and run arbitrary sections of a shell script or to redo commands with no retyping. In addition, command line tools were commonly provided with a somewhat standardized graphical interface named Commando that provided limited access to the command line capabilities of the program. The debuggers were not integrated into MPW like most IDEs of today but the language compilers supported the symbolic debugging information file format used by the debugger. MPW supported a source-level debugger called SADE (Symbolic Application Debugging Environment). SADE was not an MPW Tool, but ran as a separate application with a user interface similar to MPW.
Apple's compilers had some features that were not common on other platforms—for example, the Pascal compiler was object-oriented, while the C and C++ compilers included support for length-prefixed strings (needed for Pascal-oriented APIs).
Pascal was Apple's original preferred language for Macintosh software development,[1] and MPW was initially released with only Pascal support. A C compiler was released with MPW 2.0. The MPW C compiler was written under contract for Apple by Greenhills.[2] In addition, the original MPW C compiler was known for its casual and frequently humorous error messages ('we already did this function'),[3] as well as occasionally addressing users by name.[4] These quirks were not carried on after the PowerPC transition, when Apple replaced the originals with compilers written by Symantec. Pascal support was no longer provided by the mid-90s due to declining popularity of the language.

In April 2017, Microsoft released Visual Studio for Mac. Visual Studio Community is free for students, open-source and individual developers. It supports development of the following: Mobile with.NET: Android, iOS, tvOS, watchOS; Mac desktop apps.NET applications (in C# and F# by default) ASP.NET Web applications; Cross-platform Unity games.
MPW was always targeted to a professional audience and was seldom used by hobbyist developers due to the considerable price for the package; by the time it was made freeware it had long since been superseded by offerings from Symantec and Metrowerks, as well as Apple's own development tools inherited from NeXT and distributed for free with OS X. It was also occasionally available as a wrapper environment for third-party compilers, a practice used by both Metrowerks and Absoft among others. Apple has officially discontinued further development of MPW and the last version of OS X to run it is 10.4 'Tiger', the last one to support the Classic environment. Apple maintained a web site and mailing lists that supported the software long after its discontinuation, but that site now redirects to the Xcode page.
MPW Shell[edit]
The MPW Shell featured redirection of output to files, as well as to windows. If a file were open, the output would go to the file and to the open window. This redirection of output required significant patching out of the file system calls so that tools need not do anything special to inherit this feature: the MPW Shell did all of the work.
The MPW Shell command language was based on the Unix csh language, but was extended to support the main features of the Macintosh GUI. It had simple commands to create menus, dialogs (prompts), and new shell windows. The cursor could be controlled, and MPW scripts or tools could easily be attached to a menu item. Command key shortcuts could be specified. Window size and location could be controlled. These features were popular in commercial production environments, where complicated build and packaging processes were all controlled by elaborate scripts.
The shell had some important differences from its Unix counterparts. For instance, the classic Mac OS had nothing comparable to Unix fork(), so MPW tools were effectively called as subroutines of the shell; only one could be running at any one time, and tools could not themselves run other tools. These limitations were the inspiration for the MacRelix project, a 'Unix-like system' for classic Mac OS.[5]
Look and feel[edit]
Functionally, a worksheet is a cross between a text editor document and an xterm window. Each worksheet window is persistently bound to a file. The user may type anything anywhere in the window, including commands, which can be executed via the keyboard's Enter key; command output appears at the insertion point. Unlike an xterm window, an MPW worksheet is always in visual editing mode and can be freely reorganized by its user. Hence a worksheet can be purely a command script or purely a text document or a mixture of the two—an integrated document describing the history, maintenance procedures and test results of a software project. The commercial BBEdit text editor retains a feature it calls 'shell worksheets' on Mac OS X. The Emacs text editor provides shell buffers, a similar feature that works across platforms.
Other tools[edit]
MPW included a version of make. Its syntax was conceptually similar to that of Unix make, but the MacRomanlong f character to indicate dependencies. More significantly, since the limitations of the shell precluded the make program from running tools itself, it had to work by composing a script of compile/link actions to be run, then delivering that to the shell for execution. While this was good enough most of the time, it precluded makefiles that could make on-the-fly decisions based on the results of a previous action.
Although not implemented as MPW tools, the package also came with several source-level debuggers through its history; SourceBug and SADE (Symbolic Application Debugging Environment) were used on MC680x0 systems, while the Power Mac Debugger (known during development as R2Db[6]) provided both local and remote debugging services for PowerPC systems, the latter by using a server program known as a 'debugger nub' on the computer being debugged.
Writing MPW tools[edit]
MPW included a set of standard C libraries sufficient for developers to build their own MPW tools. Many Unix utilities could be ported with little change. One point of difficulty was the Mac OS newline convention, which was different from Unix. Another was the pathname separator, ':' in Mac OS, but many Unix utilities assumed '/'. Many Unix utilities also assumed pathnames would not have embedded spaces, a common practice on Macs.
For a number of years, the GNU toolchain included portability support for MPW as part of libiberty. This was used to support MPW-hosted cross-compilers used by General Magic and several other developers.
History[edit]
MPW was started in late 1985 by Rick Meyers, Jeff Parrish, and Dan Smith (now Dan Keller). It was going to be called the Macintosh Programmer's System, or MPS. (Notice that coincidentally the three last names start with MPS.) 'MPS ' has always been the creator signature of the MPW Shell as a result of this. Since MPW was to be the successor to the Lisa Workshop, they decided to rename it the Macintosh Programmer's Workshop. Before the arrival of MPW, Mac applications had to be cross-developed on a Lisa.
The MPW Pascal compiler is descended from the Lisa Pascal compiler. Apple's Larry Tesler worked with Niklaus Wirth to come up with Object Pascal extensions which Ken Doyle incorporated in one of the last versions of the Lisa Pascal compiler. This enabled MacApp.
Early contributors included Rick Meyers (project lead and MPW Shell command interpreter), Jeff Parrish (MPW Shell editor), Dan Smith (MPW Shell commands), Ira Ruben (assembler and many of the tools including Backup, PasMat, and more), Fred Forsman (Make, Print, SADE, and assembler macro processor), Al Hoffman (Pascal compiler) Roger Lawrence (Pascal and C compilers, including the error messages), Ken Friedenbach (linker), Johan Strandberg (Rez, DeRez, RezDet), Steve Hartwell (C libraries), and Dan Allen (MacsBug, editor). The Apple Numerics Group also contributed math libraries.
MPW 1.0 was completed on September 24, 1986. A shell memory leak was fixed on October 10, 1986, and MPW 1.0.1 was born. MPW 2.0 was completed on July 20, 1987, and MPW 3.0 was done November 30, 1988. MPW 3.1, 3.2, and 3.3 came in the next few years. MPW 3.4 was completed July 14, 1995, and MPW 3.5 was done December 17, 1999. MPW 3.6 was under development when work was halted in late 2001.
During MPW's twilight years, Greg Branche supported MPW unofficially through the Apple MPW-dev mailing list. The list, and the lists.apple.com server that hosted it, was planned to be shut down January 17, 2014,[7] a decision that was later reversed.[8]
Legacy[edit]
MPW can still be used to develop for Mac OS X, but support is limited to Carbon applications for PowerPC-based computers. To develop Mac OS X applications based on other technologies, one must use either Xcode or another OS X-compatible development environment. MPW also included a version control system called Projector; this has been superseded by modern version control systems and is no longer supported in Mac OS X.
