Hi, I've encoutered two bugs in Hugs.
I've also encountered some little things that I thought I'd tell you about.
And there's an aside, otherwise this mail would be so negative.
---- Bugs
The first bug is new in Version 970719, it wasn't in the hugs version I
used before. The function interact is not interactive anymore. Try
(interact id), and you'll see that I/O is happens per line: it's buffered.
The second bug was in the older version too. It's in genericTake in the
List library: genericTake 0 _ is undefined. And because genericTake is
recursive, no useful call of genericTake will work. Try (genericTake 10
[1..100]).
I don't think it matters, but just incase: I'm using Linux (Red Hat
release 4.2, kernel 2.0.30) on an Intel Pentium with 32 Mb of RAM. I've
installed hugs as described in the docs, and configured it with --with-x,
--plugins and --readline. It passes make check when I don't use
--readline. But the problems also occur in the W95 version.
---- Little things - these are suggestions more than anything else
Little thing number one: I don't know whether HTML URL's are supposed to
be case sensitive or not, but my browser (arena) sometimes can't follow
the links in the HTML docs because it is case sensitive... I've changed
the links in the docs - do you want them?
Little thing number two: Long filenames in hugs16.zip? I gave it to a
friend, he didn't like this at all. Can you distribute the DOS / W3.x
version with 8.3 format filenames in it?
Little thing number three: winhugs won't run on my W95 system because it
can't find ctl3d32.dll. That's right: I don't have it. Instead, I have
ctl32v2.dll. It's a brand new computer with W95 freshly installed, so
chances are that ctl3d32.dll is not distributed anymore...
---- Aside
Now that I'm mailing, I do want to thank you for Hugs, I love it! I've
been using it from the beginning, and I've used Gofer before it. I've
found it to be an enjoyable and reliable environment for my programming
experiments. One of these days I should figure out how to compile Haskell
programs, so that I won't have to rewrite my Haskell programs in C++ for
runtime performance, and then I can use Haskell for whatever I want.
In Hugs, I've written things like a program to help me learn french and an
ANN experimentation environment. I'm still working on an environment to
play with GA's (especially speeding them up using Cluster Analysis), a
program to play the oriental game of Go, and an Audio Compiler (Sound
generation) - I might combine that one with Haskore.
---- End
PS. I can't read the mailing lists, because our computer center forbids us
to subscribe to mailing lists.
Yours, Erik van der Meer.
