Not necessarily fully moderated, but there needs to be a list admin (haskell-i18n-admin(a)haskell.org) who is responsible for dealing with the messages that Mailman flags for auto-moderation, and user queries, etc. I'm already the admin for way too many lists on haskell.org, otherwise I'd volunteer myself :-) Cheers, Simon

ANNOUNCE: HaXml-1.06
by Malcolm Wallace 12 Aug '02

12 Aug '02

HaXml-1.06 ---------- http://www.haskell.org/HaXml/ We are pleased to announce a fresh release of HaXml, the collection of libraries and tools for using XML from Haskell. HaXml includes * a parser for XML; * a separate error-correcting parser for HTML; * an XML validator; * pretty-printers for XML and HTML; * a combinator library for generic XML document transformation, editing, and generation; * class Haskell2Xml which allows you to read and write ordinary Haskell data as XML; * DtdToHaskell, a tool for translating an XML DTD into equivalent Haskell types; * Xtract, a grep-like tool for XML documents. Release 1.06 is a major re-packaging of these facilities. Highlights include: * HaXml now uses the new hierarchical namespace for modules, specifically under the tree Text.Xml.HaXml. * The HaXml libraries now install as a separate `package' in both ghc and nhc98. Use -package HaXml to access them. * The library APIs are now documented using Haddock. * Due to popular request, we have added a new validator for checking generic document content against a DTD. This is available both as a library function, and as a command-line tool. * DrIFT is now distributed separately by John Meacham, with much better configuration and build support. You still only need it if you want to derive the Haskell2Xml class. * Bugfix: the lexer and parser now accept NOTATION declarations in the DTD. * Bugfix: a PublicId in a NOTATION decl is now correctly recognised by the keyword PUBLIC, not PUBLICID. * Bugfix: the HTML parser now correctly accepts stand-alone tags like IMG. * Bugfix: instances of XmlContent now accept an empty string where #PCDATA is expected. Likewise, comments, processing instructions, and character/entity references are now permitted to be scattered thoughout some #PCDATA text. * Bugfix: the OneOfN types used in code generated by DtdToHaskell are now supplied by default up to size 20, and a utility for automatically generating larger sizes is included. Regards, Malcolm

One with a > Haskell implementation, or likely to have one in the future [snip] That's easy enough. On Sun/Solaris (which I use and which came out as being very popular on the Haskell survey) characters are SIGNED, so the values run from -128 to 127 and the wrapper would be not Word8 but Int8. I think this demonstrates the perils of saying "It's safe to assume everytning is 8 bit because everything is now". Although it is the case now that the overwhelming majority of computers use data sizes based on powers of 2, it is nothing other than speculation to say that this will always be the case.

ANNOUNCE: hmake-3.06
by Malcolm Wallace 12 Aug '02

12 Aug '02

hmake-3.06 ---------- We are pleased to announce a fresh, bugfix, release of hmake, the Haskell compilation manager. The usual hmake highlights -------------------------- * hmake knows about interface (.hi) files. * hmake is compiler-independent, and allows multiple compiler versions. * hmake is aware of many pre-processors. * hmake can generate object files in a separate directory from your sources. * hmake understands the library package system. * hmake understands hierarchical module namespaces. * hmake understands the Hat tracer. What's new in 3.06 ------------------ * Better handling of package libraries. Previously, the package import directories were detected at installation time, so the addition of a new package required hmake-config to be invoked to update the config database. Also, because all of the package dirs were searched on every invocation, hmake could not warn of a missing -package flag. Now, package dirs are detected at runtime, and only for the requested packages - this fixes both problems. * Added the cmdline option list to hmake-config to display the set of Haskell compilers known to hmake. * Bugfix for the -hat option. Ensure that if a file goes through cpp before hat-trans, the resulting .hx file is moved from the temporary dir back to the build dir. * Bugfix, to ensure that hmake isn't confused by the escaped character \\ in a literal string. More info, and downloads ------------------------ http://www.cs.york.ac.uk/fp/hmake/ Regards, Malcolm Wallace

Word8 I agree with that, except that Handles should handle Chars too. It's very common to interpret files as sequences of characters, it should be as easy as with current IO module. -- __("< Marcin Kowalczyk \__/ qrczak(a)knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/

It says that sizeof (char) == 1 but doesn't say that it means 8 bits. sizeof is measured in chars, whatever it is. But limits for values of char imply that it has at least 8 bits. Perhaps we can assume some widely true facts even if ANSI C doesn't guarantee that if it makes life easier. For example that a C type corresponding to Int32 exists at all, and that different pointer types have the same representation - we already rely on that, don't we? -- __("< Marcin Kowalczyk \__/ qrczak(a)knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/
