malcolm: Thu May 2 21:26:07 CEST 2002 Update of /usr/src/master/nhc/src/hat/tools In directory hinken:/tmp/cvs-serv17995 Modified Files: HatObserve.hs Makefile SExp.hs Added Files: Pattern.hs ParseLib.hs Log Message: Re-introduce pattern queries in hat-observe. There is now a proper lexer and (combinator) parser for patterns, and it can deal with infix constructors/variables using the normal Haskell syntax. The only caveat with infix patterns is that fixity is not known, so the user must parenthesise them explicitly.

malcolm: Thu May 2 12:08:20 CEST 2002 Update of /usr/src/master/nhc/src/hat/tools In directory hinken:/tmp/cvs-serv14296 Modified Files: HatObserve.hs HatTrail.hs LowLevel.hs SExp.hs artutils.c artutils.h Log Message: Solve the problem that _ did not expand in verbose mode, and _|_ and ^C had no parent. Basically, we followed the result chain pointer too far. Now, the getResult() routine stops at the last expression before the _, ^C, or _|_, and the pretty-printer must take a quick look (peekResult()) down one link of the chain to decide how to display the expression.

olaf: Wed May 1 18:06:23 CEST 2002 Update of /usr/src/master/nhc/src/hat/lib In directory hinken:/tmp/cvs-serv7940/src/hat/lib Modified Files: Hat.hs Makefile hat.c hat.h Log Message: Modifyied both nhc98 runtime system and hat library to catch runtime errors. The nhc98 runtime system now has the global variable void (*haskellErrorHandler)(char *errorMsg) = NULL; If it is not null, it will be called for runtime errors that are not handled by Haskell's "error"; i.e. currently "out of heap" and "black hole". The hat_open function sets haskellErrorHandler to an appropriate function that writes the error message to the trace and closes it. (only if compiled for nhc98) Also added handling of arithmetic error signals to the hat library.
