ARJTDDKA ;WV/TOAD - FileMan Search All Routines ;5/24/2004  19:39
 ;;3.0T1;OPENVISTA;;JUN 20, 2004
 ;
 ; not yet tested on GT.M on VMS
 ; not tested on DSM since the overhaul to add GT.M support
 ;
 ; This routine is part of the VistA Software Search program,
 ; designed to make it easy to search through all VistA
 ; software (which can be a problem both because some VistA
 ; software is in globals and because some searches are
 ; syntactic rather than simple contains operations). This
 ; particular routine is a companion to ARJTDDKR, which searches
 ; selected routines; this one searches all routines. Traversing
 ; all routines pre-1995-Standard-MUMPS is vendor-dependent, and
 ; not all MUMPS vendors have implemented ^$ROUTINE to make it
 ; portable. In particular, GT.M's routine directory handling
 ; makes this code a touch tricky, thus this routine. The main
 ; useful entry point is ALL^ARJTDDKA.
 ;
 ; need to write $$NEXTROU
 ; need to test results
 ; need to add to ARJTDDK* check for ^[]global
 ; call David and email verified code to him for his report
 ; then upload new Seattle meeting web page
 ;
 ; Change History:
 ;    2004 05 24-25  created based on ALL^ARJTDDKR & GT.M %RSEL
 ;                   program to make ALL not DSM-specific.
 ;
 ; Table of Contents:
 ;    ALL = public subroutine to search all routines
 ;    ROUDIR = public sub for GT.M to build array of paths
 ;    PATH = private sub for ROUDIR to check & format 1 path
 ;    $$NEXTROU = private function for ROUDIR to loop thru routines
 ;
 ;
ALL(CONTAINS,FIND,EXIT) ; public subroutine: search all routines
 ;
 ; input:
 ;   .CONTAINS - array of simple contains searches to do
 ;    FIND - special code (like DSM) for more complex searches
 ;    DSM-specific ^ () global (name = space) - routine directory
 ;    GT.M-specific: $ZROUTINES, host OS directories
 ; output:
 ;   .EXIT - whether user has asked searches to end ("^")
 ;    ^XTMP("DSMROUTINES") -- see ARJJTDDK routine for docs
 ;    current device for simple feedback
 ; called by ALL^ARJTDDK -- master search option
 ; calls:
 ;    $$FMADD^XLFDT - FileMan function to add days to a date
 ;    $$DT^XLFDT - today's date in FM format
 ;    ROUDIR - for GT.M, load array of source code directories
 ;    $$NEXTROU - for GT.M, return next routine name
 ;    FEEDBACK^ARJTDDKR - give routine search feedback
 ;    SEARCH^ARJTDDKR - search each routine
 ;    RESULTS^ARJTDDKU - report results of search

NEXTROU(ROUDIRS) ; private function: for GT.M
 ;
 ; Consider eventually describing $ZSEARCH in here.
 ;
 ; This is the GT.M equivalent of DSM's $O(^ (routine)); it traverses GT.M's routine
 ; directories in the order they are prioritized in $ZROUTINES and returns each of
 ; the routine names found there, one routine per call. It uses the unusual GT.M
 ; intrinsic function $ZSEARCH which remembers its own context, which is why the
 ; previous routine name need not be passed in to get the next one. We are assuming
 ; $ZSEARCH is not already mid-search beneath us in the stack, but we use context
 ; number 1 just in case, leaving 0 in case someone else has one already running.
 ; See the GT.M Programmer Manual for documentation on how this unusual function
 ; works. We also use the GT.M $ZPARSE function to extract the routine name from the
 ; path and extension, since the former varies by OS.
 ;
 ; Input:
 ;    ROUDIRS(#)=source code path
 ;    ROUDIRS(0)=current path #
 ; Output:
 ;    ROUDIRS(0)=current path # (when changed--this slowly loops thru list)
 ; Context:
 ;    private, GT.M-specific, called only by ALL above. Calls nothing.
