How to Get Haskell for Your PC

• First, get a diskette ... a formatted one ... with no files on it, or just some small ones.
• Then, go to the ECN Lab in Felgar 300, and login on a PC.
• Put the floppy in the A: drive.
• Double-click on the "Utilities" icon.
• Double-click on the "File Manager" icon.
• Click on the S: drive icon (to select the System Drive).
• Double-click on the "distrib" directory.
• Double-click on the "hugs" directory.

  Then ...

  If you want Haskell for a Windows 95 system ...

• Drag the "hugs0.exe" file to the A: drive icon (to copy the file to the diskette).
• Drag the "hugs0.ins" file to the A: drive icon, too.
• Remove the diskette.
• Go home and put the diskette in your PC.
• Copy the two hugs0 files from the diskette to your hard drive.
• Read the "hugs0.ins" file, and follow its instructions to intall Hugs.
• Eat an apple.

  Or, if you want it for a Windows 3.x system ...

• Drag the "hugspc.zip" file to the A: drive icon (to copy the file to the diskette).
• Drag the "pkunzip.exe" file to the A: drive icon, too.
• Remove the diskette.
• Go home and put the diskette in your PC.
• Copy the two hugspc and pkunzip files from the diskette to your hard drive.
• Get to the DOS prompt, and go to the directory where the two files are.
• Enter the command "pkunzip hugspc.zip" (to extract the hugs files).
• Read the "readme.pc" file, and follow its instructions to install Hugs.
• Have a glass of orange juice.

Warning about the Windows 3.x Version of Hugs ...

The PCs in the Felgar 300 Lab run the Windows 3.x version of Hugs. To use it, double click the Programming Languages icon, then double click the Hugs icon. If you have a PC that doesn't run Windows 95, you'll be using the Windows 3.x version at home, too. Here's something you need to know:

The Windows 3.x version of Hugs lacks an important feature you'll need for all projects: it doesn't protect access to private entities in libraries. You can do most of your work on the Windows 3.x version. But, you'll need to check your project from time to time, while you're developing it, on either the Hewlett-Packard version of Hugs at ECN or the Windows 95 version at home. And, you'll need to do your final demonstration session, the one you turn in with your project, on Windows 95 or an ECN HP.

About Hugs

Both of these versions of Hugs derive from software developed by Mark Jones. His original work led to a programming language called Gofer, which is similar to Haskell, but includes several novel features, some elements of which have been incorporated into Haskell. On Valentine's Day, 1994, Mark Jones released the Haskell User's Gofer System, which merged parts of Gopher and Haskell. The Windows 95 version of Hugs, which was developed as part of the Yale Haskell Project (especially Alastair Reid) using Mark Jones's software as a starting point, integrates more of the Haskell language into Hugs and is under continuing development.

One of the primary goals of the original Gofer project and of the Hugs projects was to make modern functional languages accessible on a wide variety of computing platforms, especially widely used platforms such as Windows and Macintosh. As a result, both products are available on many computing systems. You can download it for Linux, for example, if that is the operating system you prefer - or for other versions of Unix. You can get information on how to do this from the Hugs Web site at Yale and at Nottingham.

Reporting Problems with Hugs

The Hugs Web site at Yale includes summaries of problems that people have discovered with the Hugs system. If you believe you have run into an error in the system, those summaries may help you confirm it and find an explanation or workaround. There is also an email address for error reports. Please consult with your instructor before reporting errors to the Yale project.
