Some Important Types

theirData: GGData ← NIL, -- GGData of Gargoyle viewer to search

hostData: GGData ← NIL, -- GGData of Gargoyle whose SlackProcess (and menu) we're using

commander: Commander.Handle, -- commander through which MatchTool was invoked

matchLevel: MatchLevel, -- level of search (anywhere, trajLevel, sliceLevel)

searchOp: SearchOp, -- connective for items in search

replaceOp: ReplaceOp, -- action to perform upon Yes or ChangeAll(doReplace, doOperations)

lastCaretPos: Point, -- useful until Eric adds the EditProc

And Some Important Procedures

GetMatchData: PROC RETURNS [MatchData]; -- returns the central MatchData structure (in which is stored all sorts of goodies)

GetFromData: PROC RETURNS [GGData]; -- returns the GGData of the "From" Gargoyle Viewer

GetToData: PROC RETURNS [GGData]; -- returns the GGData of the "To" Gargoyle Viewer

GetGrepData: PROC RETURNS [GGData]; -- returns the GGData of "grep" scene

GetMatchTolerance: PROC RETURNS [REAL];

GetContextSensitive: PROC [matchData: MatchData] RETURNS [contextSensitive: BOOL];

GetGGInputFocus: PROC RETURNS [theirData: GGData ← NIL]; -- returns the GGData of the current input focus (NIL if not a Gargoyle viewer)

ErrorFeedback: PROC [message: Rope.ROPE]; -- flashes an error message on the MatchTool feedback line

CenterSel: Buttons.ButtonProc; -- centers the selection of a ggData in a biscroller
