ok, here is the evil chunk of script causing the problem 


function PromptCheck (name, output, wildcs)
   health = tonumber(wildcs[1])
   mana = tonumber(wildcs[2])
   if autoHeal == 1 and var.elixBalance == "1" then
     if health < 2500 then  
	Send ("drink health")
	SetVariable("elixBalance", "0")
	var.elixBalance = "0"
	DoAfterSpecial (5, "SetVariable('elixBalance', '1')", 12)
     end --if health
     if mana < 3500 then 
	Send ("drink mana")
	var.elixBalance = "0"
	SetVariable("healthBalance", "0")
	DoAfterSpecial (5, "SetVariable('elixBalance', '1')", 12)
    end --if mana
  end -- if autoheal
end --function


The problem is that the Variable healthBalance gets the new Value, and though the new sip-command is being triggered after another Enter/Mudoutput.

This is in Lua, right? And you are using my "var" table from the example script file or this forum?

Then, these two lines are doing the same thing:


SetVariable("elixBalance", "0")
var.elixBalance = "0"


I presume you are doing this to re-enable drinking elixer after 5 seconds ...


DoAfterSpecial (5, "SetVariable('elixBalance', '1')", 12)


However with "send to script" you may as well be consistent and do it the same way:


DoAfterSpecial (5, "var.elixBalance = 1", 12)


You don't really need to quote the '1' because MUSHclient variables are always stored as strings, they will be converted for you.

I'm not sure what the variable healthBalance is being used for. You set it to zero at one point but never to any other value.

Perhaps it would work better like this:



function PromptCheck (name, output, wildcs)
  local health = tonumber (wildcs [1])
  local mana = tonumber (wildcs [2])

  if autoHeal == 1 then

    if health < 2500 and var.elixBalance == "1" then  
      Send ("drink health")
      var.elixBalance = 0
      DoAfterSpecial (5, "var.elixBalance = 1", 12)
    end --if health

    if mana < 3500 and var.healthBalance == "1" then 
      Send ("drink mana")
      var.healthBalance = 0
      DoAfterSpecial (5, "var.healthBalance = 1", 12)
    end --if mana

  end -- if autoheal
end --function

oops, I was playing around with the two sets of varibles, this is why I had a double varible assignment. After trying various combinations of varibles (Mush/Scipt) I came to the conclusion that its much easier jsut using scrip-internal ones, and even the annoying "wait-for-enter" problem is solved. The sipper works great now.

Thank you for the help.

IRE muds definitely send GA/EOR after each prompt. Nick, would it be so hard to add a checkbox so this newline is being added automatically?

You could do it easily with packets in a plugin.

I do understand that...But it's faster if a client does it itself, not some workaround plugin (GA/EOR gets sent, why just ignore it?) . To me, it is just a convenience question.

Can you get an example packet for me? What is the GA/EOR in hex? Go to Edit -> Debug Packets, and get a prompt line (and then turn it off).

Find the edit window it appeared in (underneath or nearby) and copy and paste it here. Thanks.

It is pretty straighforward for GA/EOR...

It is either IAC GA, or IAC EOR. In imperian, for example, it is IAC GA.

The packet is the following:

          H:.[32   68 65 20 6c 61 6e 64 2e 0d 0a 48 3a 1b 5b 33 32
m86.[37m M:.[32m   6d 38 36 1b 5b 33 37 6d 20 4d 3a 1b 5b 33 32 6d
117.[37m <.[32me   31 31 37 1b 5b 33 37 6d 20 3c 1b 5b 33 32 6d 65
.[37m.[32mb.[37m   1b 5b 33 37 6d 1b 5b 33 32 6d 62 1b 5b 33 37 6d
> ..               3e 20 ff f9


Notice FF F9 bytes in the end - it is IAC(FF) GA(F9). The prompt ends with > and space.

OK, I have added this to version 3.66 along with telnet negotiation for it (IAC WILL GA -> IAC DO GA, IAC WILL EOR -> IAC DO EOR).

I hope EOR is 0xEF, the documentation is a bit obscure on that point. Or is EOR 0x19 without the IAC?

At present I am recognising 0xFF 0xEF as EOR, but not 0x19 on its own.

EAR itself is IAC EOR (255, 239).

For negotiations, a command code for EOR is 25(hex 19) - is is used for IAC WILL, IAC DO and such.

As for GA negotiations, there is no IAC WILL GA options, if i got it correctly from RFC.

The only option for GA is SUPRESS-GO-AHEAD(3), it is used for well, supressing GA-s. The RFC for it is: ftp://ftp.isi.edu/in-notes/rfc858.txt

How confusing is that? Alright, I have changed the WILL/WONT to use 0x19 but the actual sequence to be acted on is still 0xFF 0xEF.

I have a question about this plugin.

It works great and achieves what I needed. However, when the trigger matches and the newline is put in, is there any way to get the next packet to start on that newline? I'm now getting an extra blank line after every prompt which is incredibly spammy when you're in combat on the MUD I play (Aetolia).

Here's an example of what my output looks like without the plugin:

H:2886 M:2952 E:14090 W:17420 B:100% [db eb]
(Novices): Bob says, "No? It is a friendly little competition that will 
earn you gold and perhaps a prize."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]
(Novices): Jim says, "Hmm, well i never did it before."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]
(Novices): Wendy says, "Ooh.. it can be fun."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]


With the plugin, the same output looks like this:


H:2886 M:2952 E:14090 W:17420 B:100% [db eb]

(Novices): Bob says, "No? It is a friendly little competition that will 
earn you gold and perhaps a prize."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]

(Novices): Jim says, "Hmm, well i never did it before."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]

(Novices): Wendy says, "Ooh.. it can be fun."
H:2886 M:2952 E:14090 W:17420 B:100% [db eb]


After each prompt, the newline is blank and the next bit of output starts on the line after that. Is there any way to gag that blank line?

I know this doesn't seem too major, but when you get into player vs. player fights on this MUD, the text starts scrolling off the screen at an incredible rate and a blank line after each prompt makes it fly off even faster.

Here's what I use to solve that problem:


<triggers>
  <trigger
   enabled="y"
   match="^([0-9]+)h, ([0-9]+)m, ([0-9]+)e, ([0-9]+)p ((?:e|)(?:l|)(?:r|)(?:x|)(?:k|)(?:d|)(?:b|)(?:|p))-$"
   regexp="y"
   script="SetPromptStats"
   sequence="0"
  >
  </trigger>
</triggers>
<triggers>
  <trigger
   keep_evaluating="y"
   match=".*"
   name="got_other_line"
   regexp="y"
   script="GotOtherLine"
   group="prompt_cleanup"
   sequence="2"
  >
  </trigger>
  <trigger
   match="^$"
   name="empty_line"
   omit_from_output="y"
   regexp="y"
   script="GotEmptyLine"
   group="prompt_cleanup"
   sequence="1"
  >
  </trigger>
</triggers>

def SetPromptStats(name, output, wildcs):
	world.EnableTriggerGroup("prompt_cleanup", 1)

def GotEmptyLine(name, output, wildcs):
	world.EnableTriggerGroup("prompt_cleanup", 0)

def GotOtherLine(name, output, wildcs):
	world.EnableTriggerGroup("prompt_cleanup", 0)


You'll need to translate that to your language of choice which shouldn't be a problem, and enable the "Triggers can match on empty line" option. This is probably most fitting inside a plugin.

Thanks Ked!

I had thought of something like this, but the ^$ trigger never fired, I imagine it's because I was unaware of the "match triggers on empty line" option.

My problem now is . . . .where is that option?!? I can't find it! :)
