UPDATE: I think my question is answered, but do not quite understand how to implement the answer. See latest post if you wish to help (please!)
i am trying to modify a map such that it relays information about the winner(s) back to some host bot. I plan to do this as described in this thread:
https://www.ghostpp.com/forum/index.php?topic=8.0
in fact, my questions are in that thread as well, but i'll paste them here anyway (it's a short thread if you'd like to just go there..)
The thread linked above provides a vJass library to do that which I am trying to do (so I'm told). However, I don't really have a clue how to use it.
More specifically, my (current) questions are two-fold and can be summed up as follows:
1) An existing map already has some default library. Should I merge the two libraries (i.e. put all of the 'globals' from the link above in the same spot as the globals in a default library, all of the functions in the same place the functions are, and so on..), replace the default library with the one in the link above, or can I just paste the whole thing at the bottom (of the war3map.j file)?
2) I believe the first question is a trivial one to answer, now comes the pay-dirt: i'm not entirely clear on how to call the function at the appropriate time. I'm guessing there is some function I'm supposed to call at the end of the game? Is that done with vjass or with the normal map editor scripts?
Assuming the library is just pasted in, my best guess is I would simply do this:
And I would repeat this trigger for each player. Is that even close to correct?

Assuming the library is just pasted in, my best guess is I would simply do this:
JASS:
function Trig_Player1_Actions takes nothing returns nothing
call FlagPlayer( GetPlayerName(Player(0)), 103 )
endfunction
//===========================================================================
function InitTrig_Player1 takes nothing returns nothing
set gg_trg_Player1 = CreateTrigger( )
call TriggerRegisterPlayerEventVictory( gg_trg_Player1, Player(0) )
call TriggerAddAction( gg_trg_Player1, function Trig_Player1_Actions )
endfunctionAnd I would repeat this trigger for each player. Is that even close to correct?
Here's the library:

/// The Map Meta Data Library
/// Version: v1.00
/// Last Modified: April 24, 2009
/// Author Chain: Strilanc, [insert next ...]
///////////////////////////////////////////////////////////////
/// This library is used to emit standardized meta data which replay parsers and bot hosts can use to record relevant
/// game statistics like "hero kills" which would otherwise be impossible to record automatically.
///
/// In particular, the flag function can be used to indicate if a leaver should be awarded a win or not. Replays
/// don't contain enough information to easily tell winners who leave from losers who leave. (for example: people
/// who leave while end-game stats are being shown)
///////////////////////////////////////////////////////////////
/// Interface:
/// void FlagPlayer(player, flag_constant)
/// void DefineValue(name, type_constant, goal_constant, suggest_constant)
/// void UpdateValueInt(name, player, operation_constant, value)
/// void UpdateValueReal(name, player, operation_constant, value)
/// void UpdateValueString(name, player, value)
/// void DefineEvent0(name, format)
/// void DefineEvent1(name, format, argName1)
/// void DefineEvent2(name, format, argName1, argName2)
/// void DefineEvent3(name, format, argName1, argName2, argName3)
/// void LogEvent0(name)

///////////////////////////////////////////////////////////////
/// Notes:
/// - Errors are displayed using BJDebugMsg
/// - Don't try to update a value before defining it
/// - Parsers expect a very specific format, don't screw with the library's output.
/// - If you emit a bunch of data per second, you will cause bandwidth problems for dial-up users. Try to avoid
/// emitting lots of data all at once except at the start and end of games or rounds.
/// - An event's format string uses {#} to represent arguments
/// - Calling RaiseGuard will increase the number of senders for each message from 1 to 3. This increases
/// security but uses more network bandwidth. It is done automatically if tampering is detected.
