Hi,

I've read all the previous posts regarding solutions for adding a newline after the prompt but I'm still unable to find a successful fix for my problem. Hopefully someone can point me in the right direction.

I want to trigger a newline on a prompt for filtering purposes. The prompt is very simple...


|1|*

I took the Plugin (below) from an old post and modified the string.gsub to read


return (string.gsub (s, "\n%|1%|%*", "%1\n"))

However this is unsuccessful. Am I correct in thinking % is the correct escape character here rather than backslash? I did also try without escape characters but it won't trigger.

The packet debug for the line looks as follows:


...[0;30;44m|1|.   0d 0a 1b 5b 30 3b 33 30 3b 34 34 6d 7c 31 7c 1b

You can see that after the newline (hex 0A) there is other stuff:


.[0;30;44m

The string.gsub needs to match that too. Or put in a wildcard, eg.


return (string.gsub (s, "\n.*%|1%|%*", "%1\n"))

Thanks, that now triggers correctly. However I realise this is not going to achieve what I want as the newline is only cosmetic client side. What I need is a Carriage return /r to reset the prompt.

I thought I could use something simple like below to put a /r in front of the newline when sending my next line but this doesn't work.


function OnPluginCommandEntered (sText)
  return string.gsub (sText, "\n", "\r\n")
end -- function

Basically what I'm trying to do is create a second window for watching another player. Much of this is fairly easy to setup as it is simply a trigger on the prompt at the beginning of the line to filter the output to the correct window.

My output has a basic prompt of *
The watched player output has a prompt of |1|*

Hence I just filter lines starting |1|* to the second dummy window.

The only problem I have is that when some watched data is sent in, my prompt line is still showing |1|* and so my command goes to the second window. This also happens the other way round... When I send a command, the first command from the watched player comes in with the standard * prompt and so goes to my main output window.

I therefore need a way to effectively reset the prompt before the line is filtered to the correct window by issuing a carriage return.

is OnPluginCommandEntered the correct function to use for this?

Decided to take a different approach by just using string.match on the packet and then sending a carriage return if the prompt line packet is found.

Need to test but it should work to revert the prompt for my commands. Not sure yet how I can do this in reverse (switch to the |1| prompt for watched users command) without initiating an infinite loop.



function OnPluginPacketReceived (s)

if string.match (s, "%[0;30;44m%|1%|.%[1;37;40m.%[0;34;40m.%[1;34;40m%*.%[0;34;40m.%[1;37;40m$") then
	Send ("\r")
end -- if
  return (s)
end -- function OnPluginPacketReceived

Ok I'm getting there now. Went back to the beginning and started from scratch. What happens now is

-I record in a variable the last command that I sent out.
-I then check each incoming line for the prompt
-When prompt is matched, I check the line to see if it matches my last command sent out.
if it does, then it's a local command and I simply add a carriage return in front to revert the prompt.
if it does not, then it's a command from the remote player and so I will need to add the |1| to the front of the line if not present
