Hi to all. I have a question, i've been killing my mind to try to figure this out, and i can't.
I have an alias, like this:
-stringo -(.*) -(.*) -(.*) -(.*)

What it does is the following:

var item;
var newitem;
var short;
var long;

item = "%1";
newitem = "%2";
short = "%3";
long = "%4";

world.send("string obj " + item + " name " + newitem);
world.send("string obj " + newitem + " short " + short);
world.send("string obj " + newitem + " long " + long);

My problem is that if the name (newitem) has 2 or more words, the code gives an error.
Example: The newitem will have the name mighty hammer gods.
When it does the short description on it, it gets the full name, mighty hammer gods, and not only one of the names. What i need is a line of code, that if it has one keyword, it uses that keyword, if it has 2 keywords, it sets the name to those 2 keywords, but when doing the short or the long, it uses only one of those keywords. And so on, if it has 3 the same thing.
What am i doing wrong?
Thank you.

It would help to post the exact alias, and the exact text that causes it to fail.

Template:copying For advice on how to copy aliases, timers or triggers from within MUSHclient, and paste them into a forum message, please see Copying XML.


However I am guessing you need to make the wildcards "non greedy" by adding a ?, like this:


 -stringo -(.*?) -(.*?) -(.*?) -(.*?)

It is used for restring objects on the MUD. I don't know if all MUD's are alike.
The error is that on the second world.send, the newitem can only have one word, and not more then one word. If i name the item like i sayd before, the string saved on the var new item will be the all name, and i only need one, the first word for example.

Can you please post an example of the MUD output that this should be matching on? Then I can test it.

This is the MUD output. The two last outputs are the error, that's why i can't do what it suposed to do.
Thank you Nick.

Nothing in your last post has "stringo" in it.

Nick,

I have posted all the outputs. I don't know what to do more :(.

The commands on the MUD are as followed:

string obj (object) name (new name)
string obj (new name) short (short description)
string obj (new name) long (long description)

These are the commands that are inputed on the MUD, so you can change the name of the object. The () are there only to show that it is what you need to input.
So i need to make an alias to do those 3 commands, in Jscript or with something else. See the (new name) that's where my problem is. If you set the new name with one word, there is no problem, but if you put 2 words on the new name, the second command don't work cause the (new name) must be entered on only one word. If i do those 3 commands, separated, by hand, they work fine.

He's trying to match that to his input rather than mud output Nick. At least I'm pretty sure that's what I'm reading in his next to last post.


Halig, try putting your newitem output in quotes if it contains multiple words. What codebase is this for? Would be a good bit easier to help you with that info.

ex: string obj "(multi-word new name)" short (short description)

Hi Meerclar,

You are right. I'm trying to match my input, not the MUD's. Thank you for that.

The codebase is based on Merc 2.1, based on Rom2.4 copyright 1993 - 1994 Russ Taylor.

It worked on what you said, put the "".
But on the script it doesn't work. How do i make an alias that makes all the three commands?

If the server doesn't complain about the " " enclosure, change your alias to put keywords in quotes so that it doesn't 'confuse' the server with multiple keywords. That's why it's failing the way you set it up initially - the server is looking for a single 'word' for keyword when you restring and it should treat "(stuff stuff stuffy stuff)" as a single 'word' and allow you to use the alias like you're trying to do. If it's still complaining with the " " enclosure, you're going to need to rework the alias to properly fit the expected input pattern which could get very tricky if you've got something that was built with a lot of keywords.

Thank you again.
The alias still getting messed up. Can you help me with the rewritten of that?
I'm really stuck, cause it works if you type one command at a time, but i want to automated that, make the three commands on one alias.

Be sure expand variables is checked or this is guaranteed to fail spectacularly.

<aliases>
<alias
match="-stringo -(.*?) -(.*?) -(.*?) -(.*?)"
enabled="y"
expand_variables="y"
group="Restring"
regexp="y"
send_to="12"
keep_evaluating="y"
sequence="100"
>
<send>var item;
var newitem;
var short;
var long;

item = "%1";
newitem = "%2";
short = "%3";
long = "%4";

world.execute(string obj @item name @newitem);
world.execute(string obj "@newitem" short @short);
world.execute(string obj "@newitem" long @long);</send>
</alias>
</aliases>


I'm pretty sure I got that right at least. Using execute rather than send should keep the expanding variables functioning properly within the quotes and if not, Nick should spot any mistakes I made fairly easily. This one's a little beyond what I normally do with aliasing and the command syntax for string is definitely complicating things.

variable name is not defined. I changed it to item, and then the newitem is not defined also.
I'm doing this in JScript.

I got better results with matching on:


^-stringo -(.*?) -(.*?) -(.*?) -(.*?)$


Example alias in Lua:


<aliases>
  <alias
   match="^-stringo -(.*?) -(.*?) -(.*?) -(.*?)$"
   enabled="y"
   expand_variables="y"
   group="Restring"
   regexp="y"
   send_to="12"
   keep_evaluating="y"
   sequence="100"
  >
  <send>
item = "%1";
newitem = "%2";
short = "%3";
long = "%4";

-- debugging
print ("item", item)
print ("newitem", newitem )
print ("short", short)
print ("long", long)

-- Lua uses .. instead of + to concatenate strings

Send("string obj " .. item .. " name " .. newitem);
Send("string obj " .. newitem .. " short " .. short);
Send("string obj " .. newitem .. " long " .. long);

</send>
  </alias>
</aliases>


Test:


-stringo -foo -bar -pedro -hello world


Output:


item foo
newitem bar
short pedro
long hello world

string obj foo name bar
string obj bar short pedro
string obj bar long hello world

Thank you Nick. But what if you insert:

-stringo -foo -bar of strenght -pedro -hello world

item foo
newitem bar of strenght
short pedro
long hello world

string obj foo name bar
string obj bar of strenght short pedro
string obj bar long hello world

The second line is where my problem resides. It can't be bar of strenght, but only bar.
