This commit splits up and factors out the numerable tasks that the main hugs.c file had become burdened with over the years. The following new modules have been introduced: * evaluator.{c,h} -- evaluator engine * errors.{c,h} -- error handling + output * goal.{c,h} -- handling progress towards interp goals. * observe.{c,h} -- observation specific code (Note: support is only available in interactive builds.) * opts.{c,h} -- parsing and representing interpreter options. * strutil.{c,h} -- string utilities (not too much in here at present, but will grow.) * HugsAPI.h -- the public header file for the HugsAPI; server.h is now assumed to be internal to the Hugs sources. * server.c -- now a separate module; no longer literally includes hugs.c * hugs.c -- now only responsible for handling the interactive UI and all its commands. * winhugs/winhugs.c -- separate module; no longer literally included by hugs.c Code that supports a separate evaluator thread has been moved to here (from hugs.c) This was all brought about by wanting to expose the HugsAPI / server interface to external code (invoked via the FFI), and also re-use some of the server.c code to provide an extended version of the HugsAPI. What seemed like an innocent little change at first turned out not to be! [Untested on autoconf-based plats; true to form, I've no doubt mucked up Makefile.in some.] Revision Changes Path 1.41 +47 -32 hugs98/src/Makefile.in 1.51 +6 -65 hugs98/src/builtin.c 1.2 +6 -3 hugs98/src/builtin.h 1.16 +3 -2 hugs98/src/compiler.c 1.71 +48 -70 hugs98/src/connect.h 1.9 +7 -16 hugs98/src/errors.h 1.26 +3 -2 hugs98/src/ffi.c 1.121 +98 -1697 hugs98/src/hugs.c 1.3 +6 -0 hugs98/src/hugsscript.c 1.62 +8 -7 hugs98/src/input.c 1.48 +2 -3 hugs98/src/iomonad.c 1.82 +15 -4 hugs98/src/machdep.c 1.2 +20 -3 hugs98/src/machdep.h 1.30 +3 -2 hugs98/src/output.c 1.44 +2 -44 hugs98/src/prelude.h 1.16 +8 -5 hugs98/src/runhugs.c 1.3 +78 -4 hugs98/src/script.c 1.2 +13 -2 hugs98/src/script.h 1.32 +63 -72 hugs98/src/server.c 1.10 +18 -68 hugs98/src/server.h 1.146 +6 -2 hugs98/src/static.c 1.66 +5 -2 hugs98/src/storage.c 1.27 +4 -2 hugs98/src/subst.c 1.69 +4 -2 hugs98/src/type.c 1.27 +45 -28 hugs98/src/msc/Makefile 1.16 +57 -29 hugs98/src/winhugs/Makefile 1.6 +5 -7 hugs98/src/winhugs/Winbrows.c 1.6 +7 -10 hugs98/src/winhugs/Winhugs.h 1.13 +154 -19 hugs98/src/winhugs/winhugs.c
