malcolm: Tue Jan 30 17:53:47 CET 2001 Update of /usr/src/master/nhc/src/compiler98 In directory hinken:/tmp/cvs-serv26585 Modified Files: LexPre.hs Log Message: Accept {-# pragmas #-} anywhere (removed in the same way as comments) provided we don't recognise the pragma name. A recognised pragma still requires a proper parser. Also, some tidying of this source file to 80-column format.

malcolm: Thu Jan 25 18:34:23 CET 2001 Update of /usr/src/master/nhc/src/prelude/IO In directory hinken:/tmp/cvs-serv10801 Modified Files: HPutStr.hs Log Message: IO.hPutStr now calls a new C primitive on the whole string, rather than laboriously hPutChar'ing each character through the IO monad. This gives a pure speed improvement of 5-10x over the naïve way.

malcolm: Thu Jan 25 18:24:32 CET 2001 Update of /usr/src/master/nhc/src/runtime/Builtin In directory hinken:/tmp/cvs-serv10729 Modified Files: cHPutStr.c Log Message: Add a new primitive implementation of hPutStr that packs Strings before outputting them. We 'chunk' the string as we evaluate it lazily, so as not to use too much space if the string is very long. But we also need to be careful to do this correctly with respect to the buffering mode (char,line,block). Initial performance measurements show a 5-10x speedup for output, depending on the length of the original string and the buffering mode.

Default nesting depth before truncating display is 7 instead of 5. Visual symbol for truncating is now a small diamond (in Latin1).
