2000-04-01 ast message catalog plan

(1) error_info.dictionary should be error_info.catalog
    to match xopen and the internal naming in our implementation
    and also to more closely match the webster definition
    (catalog == enumerated list)

    DONE

(2) nmake by default will
	CATALOG = $(ID:N=+([A-Za-z0-9_]):?$(PWD:N=*/lib/*:Y,lib,,)$(ID)?$(PWD:B)?)
	ERROR_CATALOG == "$(CATALOG)"
    e.g., commands in src/cmd/std will use the "std" catalog; all of the
    commands in src/lib/libcmd will use the "libcmd" catalog

    nmake will add "[--catalog?$(CATALOG)]" to USAGE_LICENSE
    optget() will set error_info.catalog if not defined on the first call
    commands that don't emit messages before optget() need not change
    otherwise the command should

	error_info.id = "foo";
	error_info.catalog = ERROR_CATALOG;

    undefined references to { USAGE_LICENSE ERROR_CATALOG } are hard
    compile time errors

    DONE

(3) add catalog argument to libcmd <cmd.h> cmdinit(argv, context, catalog)

    DONE

(4) msgcat global target build msgs/*.mso and $(CATALOG).msg
    each Makefile will generate one catalog $(CATALOG).msg where

    the *.msg files are weird -- we need to build them viewed over an
    architecture specific tree, even though they will be eventually used
    as architecture independent source

    $(CATALOG).msg will be the "C" locale

    debug will be a debugging locale that will translate each message to
	(CATALOG-NAME:MESSAGE-INDEX)\n
    this will make it easy to locate text that escaped translation (in what
    should be translated output); it will also be a way for us to do
    regression tests in the face of typo fixes -- presumably typos can be
    fixed without changing the message index

    see msgadmin(1)

    DONE

(5) once all this is working I'll do catopen(3) and msggen(1)

    DONE

(6) the makerules "all" action will
	catgen $(CATALOG).cat
	catgen $(CATALOG)-*.cat
    and the makerules "install" action will copy the catgen output to
	$(LOCALEDIR)/$(LOCALE)/LC_MESSAGES/$(CATALOG)*
    where
	LOCALEDIR = $(INSTALLROOT)/lib/locale

    NOTE: still under consideration
