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for purchase as part of Apple's professional developers program, but Apple made it a free download after it was superseded by CodeWarrior.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.
Mac users running earlier versions of OS X can access this article Xcode Command Line Tools.

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).
私の環境には2つのcommand line toolsがインストールされています。 下記、1と2を切り替えながら使いたいのです。 XCodeのPreferencesのlocationsのCommand line toolsのところを見ても、XCodeに付属してきたものだけが表示されており、切り替えられません。. If you perform a fresh install of Xcode, you will also need to add the commandline tools by running xcode-select-install on the terminal. While OS X comes with a large number of Unix utilities, those familiar with Linux systems will notice one key component missing: a decent package manager. However whenever there's a command line tools update, the App Store keeps showing up to update it. – adib Jun 13 '18 at 22:53 Long time ago I used a DMG (needed to install an older version of the command line tools, but that's another story).
Pascal was Apple's original preferred language for Macintosh software development, 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. In addition, the original MPW C compiler was known for its casual and frequently humorous error messages ('we already did this function'), as well as occasionally addressing users by name. 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.
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.

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.
Look and feel
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.
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) 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
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.
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, a decision that was later reversed.
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.

With an all-new design that looks great on macOS Big Sur, Xcode 12 has customizable font sizes for the navigator, streamlined code completion, and new document tabs. Xcode 12 builds Universal apps by default to support Mac with Apple Silicon, often without changing a single line of code.
Designed for macOS Big Sur.
Xcode 12 looks great on macOS Big Sur, with a navigator sidebar that goes to the top of the window and clear new toolbar buttons. The navigator defaults to a larger font that’s easier to read, while giving you multiple size choices. New document tabs make it easy to create a working set of files within your workspace.
The new tab model lets you open a new tab with a double-click, or track the selected file as you click around the navigator. You can re-arrange the document tabs to create a working set of files for your current task, and configure how content is shown within each tab. The navigator tracks the open files within your tabs using strong selection.
Navigator font sizes.
The navigator now tracks the system setting for “Sidebar icon size” used in Finder and Mail. You can also choose a unique font size just for Xcode within Preferences, including the traditional dense information presentation, and up to large fonts and icon targets.
Code completion streamlined.
A new completion UI presents only the information you need, taking up less screen space as you type. And completions are presented much faster, so you can keep coding at maximum speed.
An all-new design groups all critical information about each of your apps together in one place. Choose any app from any of your teams, then quickly navigate to inspect crash logs, energy reports, and performance metrics, such as battery consumption and launch time of your apps when used by customers.
SwiftUI offers new features, improved performance, and the power to do even more, all while maintaining a stable API that makes it easy to bring your existing SwiftUI code forward into Xcode 12. A brand new life cycle management API for apps built with SwiftUI lets you write your entire app in SwiftUI and share even more code across all Apple platforms. And a new widget platform built on SwiftUI lets you build widgets that work great on iPad, iPhone, and Mac. Your SwiftUI views can now be shared with other developers, and appear as first-class controls in the Xcode library. And your existing SwiftUI code continues to work, while providing faster performance, better diagnostics, and access to new controls.
Universal app ready.
Xcode 12 is built as a Universal app that runs 100% natively on Intel-based CPUs and Apple Silicon for great performance and a snappy interface.* It also includes a unified macOS SDK that includes all the frameworks, compilers, debuggers, and other tools you need to build apps that run natively on Apple Silicon and the Intel x86_64 CPU.
When you open your project in Xcode 12, your app is automatically updated to produce release builds and archives as Universal apps. When you build your app, Xcode produces one binary “slice” for Apple Silicon and one for the Intel x86_64 CPU, then wraps them together as a single app bundle to share or submit to the Mac App Store. You can test this at any time by selecting “Any Mac” as the target in the toolbar.
Test multiple architectures.

On the new Mac with Apple Silicon, you can run and debug apps running on either the native architecture or on Intel virtualization by selecting “My Mac (Rosetta)” in the toolbar.
New multiplatform app templates set up new projects to easily share code among iOS, iPadOS, and macOS using SwiftUI and the new lifecycle APIs. The project structure encourages sharing code across all platforms, while creating special custom experiences for each platform where it makes sense for your app.
Swift code is auto-formatted as you type to make common Swift code patterns look much better, including special support for the “guard” command.
New tools in Xcode let you create StoreKit files that describe the various subscription and in-app purchase products your app can offer, and create test scenarios to make sure everything works great for your customers — all locally testable on your Mac.
