ok so it seems as if the following works on the majority

function OnPluginPacketReceived (s)
  return (string.gsub (s, "\n> ", "\n"))
end -- function OnPluginPacketReceived

however, it does not work on all of them, for the rest the following works, but I can't seem to get the rest to work due to the "[" it throws an error... I used an \ before the bracket but it still says expecting "]" or some such...

function OnPluginPacketReceived (s)
  return (string.gsub (s, "0m> ", ""))
end -- function OnPluginPacketReceived


How can I combine this to catch both cases with a newline on each?

You have: \r \n \027 [ 0 m >

In Lua regular expressions, you have to escape a square bracket with a % rather than a backslash.

Something like this:


function OnPluginPacketReceived (s)
  s = string.gsub (s, "\r\n\027%[0m> ", "")
  return (string.gsub (s, "\r\n> ", ""))
end -- function OnPluginPacketReceived


The first string.gsub deals with the lines with the ANSI sequence in it, the second then fixes up the others.

  return (string.gsub (s, "\r\n> ", "\n"))
end -- function OnPluginPacketReceived

So, I had to add back in the \n, because I'm removing a new line without it in there. Also, in the first portion, I added the color code back in, as it was changing the colors, etc... similarly it also needed a new line. Now, the only time I see the > is when I send a carriage return. In which case I see a blank line and then a line with only the "> " on it.

I tried adding in your omit blank lines plugin as well, to get of half the spam in that instance, but it doesn't seem to be the issue.

What you said makes sense. :) I probably stripped away too many newlines.

You could always fix the problem with the packet with just 3e 20 in it by adding a line:


if s == "> " then
  return ""
end -- if only a prompt

works so far, it seems to be gone from everything but when I first log, which is no big deal. Thanks again Nick!

think you can give me a hand?

right now I am using...


function OnPluginPacketReceived (s)
  s = string.gsub (s, "\r\n\027%[0m> ", "\n\027%[0m")
  s = string.gsub (s, "\r\n> ", "\n")
  
  if s == "> " then 
    return ""
  else
    return (s)
  end

end -- function OnPluginPacketReceived

You mean the very last one? Looks like it is at the end of the packet (999 bytes) and probably the MUD has broken the output up at the 999 byte mark. It is hard to catch those without batching up packets.

hmm... I guess its a no-go then. No biggy, I'll try to look at it later when I understand more about these packets and such. Thanks again though.

This thread has an example of concatenating packets until you get a whole line:

http://mushclient.com/forum/?id=7430

What you can do in OnPluginPacketReceived is concatenate packets first (storing a partial line in the plugin), and then extract out whole lines. These can then be reliably checked for prompts.

Ok, now I'm unfamiliar with LUA, so bear with me... Here is what I have after looking at that page...
partial = ""

function OnPluginPacketReceived (s)

	partial = partial .. string.gsub (s, "\r", "")
	t = {}

	partial = string.gsub (partial, "(.-)\n", 
		function (line) 
		table.insert (t, line) 
		return ""
		end)

	partial = string.gsub (partial, "\r\n\027%[0m> ", "\n\027%[0m")
	partial = string.gsub (partial, "\r\n> ", "\n")
	
	if partial == "> " then 
		partial = ""
	end

	if table.getn (t) > 0 then
		table.insert (t, "")
	end

	return table.concat (t, "\n")

end


Now, I hope I'm doing this correctly... The triggering on regular expressions didn't work to get rid of the "> ". So its not currently in the plugin.

It doesn't actually display the query "Name:" and "Password:" until after I have already typed them in...

No, once you have done the string.gsub, all the lines except the last partial one will be in the table "t", not in the string "partial", so doing a string.gsub on that won't achieve anything.

So now you have a table of lines, so you do your matches on that, eg.


partial = ""

function OnPluginPacketReceived (s)

  -- get rid of carriage-returns
  
  partial = partial .. string.gsub (s, "\r", "")
  local t = {}

  -- turn finished lines into table t
  
  partial = string.gsub (partial, "(.-)\n", 
    function (line) 
    table.insert (t, line) 
    return ""
    end)

  -- get rid of prompts  (in a regexp, ^ indicates the start of a line)
  
  for i, line in ipairs (t) do
    t [i] = string.gsub (line, "^\027%[0m> ", "\027%[0m")
    t [i] = string.gsub (line, "^> ", "")
  end -- for
  
  -- reassemble completed packet with line-based corrections
  
  local fixed_packet = ""
  
  -- drop completely empty lines
  for i, line in ipairs (t) do
    if line ~= "" then
      fixed_packet = fixed_packet .. line .. "\n"
    end -- if
  end -- for
  
  return fixed_packet

end -- OnPluginPacketReceived


(Disclaimer: I didn't test or compile the above code).

That is exactly what you expect to happen if you batch up lines until you get a newline character. You probably need to do nothing with the incoming packets until some flag is set to indicate you have finished the login sequence.

Or, use the "auto-login" function in MUSHclient which sends down the username and password as soon as you connect, so they will be supplied even if you don't see the question.

More simply, you might fix up the prompts as you build the table, like this:


partial = ""

function OnPluginPacketReceived (s)

  local t = {}  -- table of reassembled lines

  -- get rid of carriage-returns, add new packet to existing partial one
  
  partial = partial .. string.gsub (s, "\r", "")

  -- turn finished lines into table t
  
  partial = string.gsub (partial, "(.-)\n", 
    function (line) 
      
      -- remove prompt as we add to the table
      
      line = string.gsub (line, "^\027%[0m> ", "\027[0m", 1)
      line = string.gsub (line, "^> ", "", 1)
         
      if line ~= "" then
        table.insert (t, line) 
      end -- if not empty
      
      return ""
    end) -- function
  
  if #t > 0 then
    table.insert (t, "")  -- to get final linefeed
  end -- if
    
  -- return table of lines, concatenated with newlines between each one
  return table.concat (t, "\n")

end -- OnPluginPacketReceived
