> It appears that building GHC requires Happy. It appears that > building Happy requires GHC. How does one bootstrap this thing ? Building GHC shouldn't really require Happy, but there's a bug in the 5.02 source distribution which means that the configure script complains if you don't have Happy installed. Hacking the configure script to remove the check will get you going. (as Simon said you still need GHC, though). Cheers, Simon

RE: Andy Gill's html library
by Keean 26 Jun '02

I have an alternative HTML library if you are interested... it uses an intermediate representation (a DOM style model) and defines the type ShowDOM = DOM -> DOM , allowing efficent concatination using function composition, finally a layer on top of this using the type ShowDOM -> (a,ShowDOM), instanciating a Monad allows monadic composition of html pages - there is also some static type checking done by creating the types: newtype HtmlFragment = HtmlFragment (ShowDOM -> (a,ShowDOM)) newtype HtmlTableFragment = HtmlTableFragment (ShowDOM -> (a,ShowDOM)) etc... this allows you to compose HTML as in the following example attrTable [MkAttribute ("cellspacing","0")] ( do htmlTR (attrTD [MkAttribute ("colspan","2")] $ htmlText "Test Cell 1")) htmlTR ( do htmlTD (htmlText "Cell 2 (Left)") htmlTD (htmlText "Cell 3 (Right)"))) If you (or anyone) are interested let me know ...

Just my feeling, but perhaps it is essentially the same reason why ShowS is String -> String rather than String, so that concatenation becomes efficient? _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users(a)haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Building GHC requires GHC too, not just Happy. The best thing to do is usually to download and install both GHC and Happpy, which is what the building guide recommends http://haskell.cs.yale.edu/ghc/docs/latest/building/sec-pre-supposed.htm l You can get away with downloading just GHC, building Happy, and then building GHC.

compiling hmake on Mac OS X
by Kristofer Johannisson 25 Jun '02

25 Jun '02

I would just like to check if anyone on the list has managed to compile the tool hmake with ghc (version 5.03) on Mac OS X? I'm having some trouble with this (even though I got some hints from Malcolm Wallace, the author of hmake), and I would like to find out if my troubles are related to ghc on OS X, or to something else. / Kristofer Johannisson
