malcolm: Fri Jul 19 17:31:57 CEST 2002 Update of /usr/src/master/nhc/src/hat/tools In directory hinken:/tmp/cvs-serv21893 Modified Files: SExp.hs Log Message: When pretty-printing string expressions, avoid the appearance of [...] due to cutoff depth, for instance in the following: ["one","tw...","t...",[...],...] The solution is to peek one character ahead of the cutoff depth in order to decide between string/list sugaring. The example above becomes: ["one","two","th..","f...",...] given the same cutoff depth.

Fix field update bug in trusted transformation.

olaf: Fri Jul 19 15:28:25 CEST 2002 Update of /usr/src/master/nhc/src/hat/trans In directory hinken:/tmp/cvs-serv20164/src/hat/trans Modified Files: TraceTrans.hs Log Message: Fix field update bug in trusted transformation. Any field update caused a Prelude.undefined error, because the transformation checks that a combinator of the desired arity exists. The untrusted update combinator does not have an arity. Pretending that it has arity -1 solves the problem.

malcolm: Thu Jul 18 11:28:19 CEST 2002 Update of /usr/src/master/nhc/src/hat/trans In directory hinken:/tmp/cvs-serv24600/hat/trans Modified Files: AuxFile.hs AuxFixity.hs Flags.hs HatTrans.hs TraceTrans.hs Added Files: Makefile Makefile.inc PrettyTraceId.hs Log Message: Make hat-trans more separate from the compiler. This is a fairly large change. * There is a new directory src/hat/trans for all the modules that are specific to hat-trans and have no purpose in the ordinary compiler, e.g. AuxFile.hs, TraceTrans.hs, etc. * However, these modules still depend on several parts of the compiler, so the new hat-trans Makefile uses the compiler directory as a `library' of supporting material. * A few small functions needed to be moved around to different modules within the compiler, just to reduce the number of dependencies from hat-trans. * The module Flags.hs now appears in both directories - so each of the compiler and hat-trans can now support a different (partially overlapping) set of command-line flags.

malcolm: Thu Jul 11 17:01:24 CEST 2002 Update of /usr/src/master/nhc/src/hat/tools In directory hinken:/tmp/cvs-serv17947 Modified Files: HatObserve.hs Observe.hs Pattern.hs observe.c observe.h Log Message: Permit arity-raising of cafs/functions in hat-observe. Unfortunately, the equations you see can be confusing, so this feature should be considered experimental. For instance, if f x = g x g x y = x+y then observing `f' shows e.g. `f 1 = g 1', but observing `f _ _' shows e.g. `g 1 2 = 3', not `f 1 2 = 3' as you might expect. This commit also fixes the `:set recursive off' bug whereby observing `f in f' showed the non-recursive calls of f instead of the recursive ones.
