------------------------------------------------------------------------------ __ __ __ __ ____ ___ _________________________________________ || || || || || || ||__ Hugs 98: Based on the Haskell 98 standard ||___|| ||__|| ||__|| __|| Copyright (c) 1994-2001 ||---|| ___|| World Wide Web: http://haskell.org/hugs || || Report bugs to: hugs-bugs(a)haskell.org || || Version: Dec 2001 _________________________________________ ------------------------------------------------------------------------------ We are pleased to announce a new release of Hugs98, a Haskell interpreter and programming environment for developing cool Haskell programs. Sources and binaries are freely available on the World-Wide Web. The most important features of this new release are: - The incompatibilities between Hugs and the Haskell Graphics Library have been fixed, and binaries for the HGL are now available on the Hugs download page. - The missing standard libraries Directory, CPUTime, Time and Locale have been added along with a complete implementation of Haskell98 IO. - Hugs is now delivered with most of the hslibs libraries installed in the lib/exts/ directory. The added modules cover the Edison, Parsec, HaXml, QuickCheck, concurrent, monad, and html subdirectories of hslibs. - The :set option now refuses the user to set a module search path that doesn't contain the Prelude. This is to protect users from accidentally rendering their Hugs setups unusable, esp. so on Windows machines where the options are persisted to the Registry. - MacOS X is now one of the supported unix ports, with pre-built binaries available on the download page. - Experimental support is provided for hierarchical module names, where a module name A.B.C is mapped onto the file path A/B/C{.hs,.lhs} and appended to each of the path prefixes in HUGSPATH until the name of a readable file is found. Most reported bugs have also been fixed; however, some issues still remain. See the heading "Hugs Bugs & Features" on the Hugs web site for further information. Send email to hugs-users-request(a)haskell.org to join the hugs-users mailing list. Bug reports should be sent to hugs-bugs(a)haskell.org.

hugs for MacOS X
by Stephen Harris 04 Jan '02

04 Jan '02

Hi, I downloaded hugs for MacOS X (I'm running 10.1) and ran the installer, but there are no files in the indicated places, no man page and I can't run the interpreter. Any idea what I'm doing wrong? Thank you! Stephen Harris

Re: patch for `interact'
by Sigbjorn Finne 28 Dec '01

[Cc'ing hugs-users] Thanks, this is a long-standing and known feature of Hugs' interact implementation, so before possibly bringing it into line with what Haskell 98 tells us how `interact' ought to behave regarding echoing of input, it would be prudent to first check whether anyone depends on the current behaviour. In particular, are there 'important' resources (e.g., textbooks and tutorials) based around Hugs98 that depend on the current non-echoing behaviour? Or are there other weighty arguments in favour of maintaining status quo? --sigbjorn ----- Original Message ----- From: "Malcolm Wallace" <Malcolm.Wallace(a)cs.york.ac.uk> To: <hugs-bugs(a)haskell.org> Sent: Tuesday, December 18, 2001 02:56 Subject: patch for `interact' > There is a bug in Dec2001 Hugs (and earlier releases too) which causes > the Prelude function `interact' to behave unexpectedly - the user's > input is not echoed to the screen as she types it.

Announce: Hugs Graphics Library
by Sigbjorn Finne 15 Dec '01

15 Dec '01

We are pleased to announce a new release of the Hugs Graphics Library, version 2.0.4. The Hugs Graphics Library gives the programmer access to the most interesting and portable parts of the Win32 and X11 library. The library is distributed as open source and is suitable for use in teaching and applications. This version is compatible with the December 2001 release of Hugs, but won't work with the February 2001 release. This version supports: * filled and unfilled 2-dimensional objects (text, lines, polygons, ellipses). * Bitmaps (Win32 version only, for now). * Control over text alignment, fonts, color. * Simple input events (keyboard, mouse, window resize) to support reactivity. * Timers and double-buffering to support simple animation. * Use of concurrency to avoid the usual inversion of the code associated with event-loop programming. * Multiple windows may be handled at one time. To keep the library simple and portable, the library makes no attempt to support: * User interface widgets (menus, toolbars, dialog boxes, etc.) * Palette manipulation and other advanced features. * Many kinds of input event. The library can be downloaded from: http://www.haskell.org/graphics/. Installation instructions are in graphics-2.0.4/Install. Bug reports should be sent to reid(a)cs.utah.edu Enjoy!
