I'm running MUSHClient on Windows 10 so I can't use the help files. I tried looking this up in the online documentation but had no luck there either. What I want to do is make a trigger that captures a line of text. For example, when I raise a level in my MUD I get this:

You raise a level!! Your gain is: 15/70 hp, 4/94 m, 14/164 mv 3/3 prac.

So I want to make a trigger: "You raise a level!!" so that every time I raise a level that line is captured and appended to a text file so that I have all my level gains for this character.

The online documentation is exactly the same content anyway.

Don't forget to also search the forum.

Maybe https://www.mushclient.com/forum/bbshowpost.php?bbsubject_id=9921

I did search the forum and I saw that post but it didn't help... or I didn't understand it anyway. When I'm in the Trigger dialog box I can Send to: Notepad (append to) but there's no where for me to select the text file to send it to. I don't want to create a new text file for each line of text it captures. I want each line captured appended to the existing file that I've already created.

The notepad isn't a file, it's a window. If you use the trigger option it sends to a window, either a new one each time or appending to one. The window name is "Trigger: (trigger name)". Later you can save that to disk if you want.

If you want to append to a disk file then you could use the Lua "io" functions to open the file if it isn't open (eg. for appending) and then write a line each time. Something like this:


<triggers>
  <trigger
   enabled="y"
   match="Exits: *"
   send_to="12"
   sequence="100"
  >
  <send>

f = assert (io.open (GetInfo (67) .. "test.txt", "a"))  -- open file for appending
f:write ("%0\\n")  -- write trigger data plus linefeed
f:close ()  -- close it

</send>
  </trigger>
</triggers>

This is a bit inefficient because it opens the file every time, but at least that way it is usually closed, and that way you can delete or rename it while it isn't actually in use.

GetInfo (67) returns the "worlds" directory, you can choose another directory for the file if you want.

There is a "MUSHclient_Help" plugin that ships with the client. You can read all the help files in the output window using that.

Thanks Nick. I have 3 questions:

1. How do I use quote boxes and code boxes like you do?

2. You said "GetInfo (67) returns the "worlds" directory, you can choose another directory for the file if you want." I'm confused by this. Say the file I create is located at C:\Users\Bishop\Documents\MUD\MyMud. Would I write:

f = assert (io.open (GetInfo (67) .. "C:\Users\Bishop\Documents\MUD\MyMud\Myfile.txt", "a"))

3. If not how would I assign the file directory and what does GetInfo(67) have to do with it?

Omit the GetInfo, and you double the backslashes because of the way Lua works. Better is probably to use forward slashes:


f = assert (io.open ("C:/Users/Bishop/Documents/MUD/MyMud/Myfile.txt", "a"))

All GetInfo(67) does is return the directory name. Try doing:


print (GetInfo(67))

(You need to open up the scripting Immediate commands window - Ctrl+I to do this).

Excellent. Two more thing. If the trigger data goes here:

f:write ("%0\n")  -- write trigger data plus linefeed

I'm assuming between the backslashes:

f:write ("%0\You raise a level!!\n")  -- write trigger data plus linefeed

Then whenever the MUD outputs that snippet the whole line will be captured and appended to the file?

Also, what if I wanted to insert additional text before the line in the text file? If the above works like I think it does then what I'll see in my text file for the first 3 levels is this:


You raise a level!!  Your gain is: 15/70 hp, 4/94 m, 14/164 mv 3/3 prac.
You raise a level!!  Your gain is: 16/86 hp, 6/100 m, 10/184 mv 3/6 prac.
You raise a level!!  Your gain is: 14/100 hp, 7/107 m, 11/205 mv 3/9 prac.

But what I really want to see is this:


Level 2: You raise a level!!  Your gain is: 15/70 hp, 4/94 m, 14/164 mv 3/3 prac.
Level 3: You raise a level!!  Your gain is: 16/86 hp, 6/100 m, 10/184 mv 3/6 prac.
Level 4: You raise a level!!  Your gain is: 14/100 hp, 7/107 m, 11/205 mv 3/9 prac.

How do I accomplish this?

I'm getting an error trying to compile this code. This is what my code looks like:


<triggers>
  <trigger
   enabled="y"
   match="Exits: *"
   send_to="12"
   sequence="100"
  >
  <send>

f = assert (io.open ("C:/Users/Bishop/Documents/MUD/MyMud/Myfile.txt", "a"))  -- open file for appending
f:write ("%0\You raise a level!!\n")  -- write trigger data plus linefeed
f:close ()  -- close it

</send>
  </trigger>
</triggers>

And this is the error I'm getting:


[string "Immediate"]:1: unexpected symbol near '<'

Fiendish USA Global Moderator Tue 22 Nov 2016 11:43 AM #9

Your fwrite is busted.
\Y is not a valid escape sequence, and \n should be \\n.

BishopOsiris USA Tue 22 Nov 2016 05:30 PM #10

I tried:


f:write ("%0\\You raise a level!!\\n")

and


f:write ("%0\You raise a level!!\\n")

They both give me the same error as before. Not sure what you mean by

Quote:

\Y is not a valid escape sequence

If that's not corrected with \\Y then what's it looking for?

BTW I have a LUA book on it's way so hopefully it will shed some light on all of this.

Nick Gammon Australia Forum Administrator Tue 22 Nov 2016 08:45 PM #11

He means you put a backslash before the Y in You, which is not valid.

As for \\n, in "send to script" MUSHclient first interprets escape sequences itself, before the code hits Lua. You need to double the backslashes in "send to script". This doesn't apply if you use a script file or scripting in a plugin.

You can do whatever you want. You might use string.format to format the line.

BishopOsiris USA Tue 22 Nov 2016 11:44 PM #13

This script:


<triggers>
  <trigger
   enabled="y"
   match="Exits: *"
   send_to="12"
   sequence="100"
  >
  <send>

f = assert (io.open ("C:/Users/Bishop/Documents/MUD/MyMud/Myfile.txt", "a"))  -- open file for appending
f:write ("%0You raise a level!!\\n")  -- write trigger data plus linefeed
f:close ()  -- close it

</send>
  </trigger>
</triggers>

Simply will not compile. It keeps giving me this same generic error


[string "Immediate"]:1: unexpected symbol near '<'

Which really doesn't tell me anything.

I don't know what I'm doing wrong...

Nick Gammon Australia Forum Administrator Wed 23 Nov 2016 02:20 AM #14

Hmm, that isn't a script, that's a trigger.

For advice on how to copy the above, and paste it into MUSHclient, please see Pasting XML.

The script part is:


f = assert (io.open ("C:/Users/Bishop/Documents/MUD/MyMud/Myfile.txt", "a"))  -- open file for appending
f:write ("%0You raise a level!!\\n")  -- write trigger data plus linefeed
f:close ()  -- close it
