Want an alias to repeat a command x times

I just starting using MushClient and have always been a Zmud user. My question is how I go about doing a repeat on the command line or in an alias/trigger.

For example. In Zmud I would have entered the following:

<command line> #7 drink potion

the output would have been 7 lines of drink potion.

Is there something similar for that in Mushclient?

Help!

There is a bit of a discussion about this here:

http://www.gammon.com.au/forum/?bbsubject_id=3311

A fairly good way is to simply add this alias (I have amended the one in the above thread a bit to use Lua, as that is now the recommended script language):


<aliases>
  <alias
   match="^#(\d+) (.*?)$"
   enabled="y"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>Execute (EvaluateSpeedwalk ("%1 (%2)"))</send>
  </alias>
</aliases>

See http://mushclient.com/pasting for how to add this into your world.

The alias above uses EvaluateSpeedwalk to do things repeatedly (as in, you can do 4n or 4(burp)).

However that one fails if you have a bracket in the thing you are trying to do (as that will confuse EvaluateSpeedwalk). The version below simply does a loop, so that might be better:


<aliases>
  <alias
   match="^#(\d+) (.*?)$"
   enabled="y"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>

for i = 1, %1 do
  Execute "%2"
end -- for loop

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

All that does is take the number you supply, and do the command that many times.

Maybe it is wise to check the repeat count is not too small or too big, this is my final version:


<aliases>
  <alias
   match="^#(\d+) (.*?)$"
   enabled="y"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>

if %1 &lt; 1 then
  ColourNote ("white", "red", "Too few repeats specified (%1)")
  return
end -- if

if %1 &gt; 50 then
  ColourNote ("white", "red", "Too many repeats specified (%1)")
  return
end -- if

for i = 1, %1 do
  Execute "%2"
end -- for loop

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

The reason I used "Execute" in the script is to send whatever you typed back through the command processor.

You could substitute "Send" for "Execute" but then whatever you type is literally sent (which may be OK).

The difference shows up if you use aliases or speedwalks.

Say for example you have an alias "healme" (which might do "drink potion").

If you want to be able to type:



#5 healme

Then you want to use the alias I posted above.

See:

and

Okay,

I think I understand what you did. I followed your suggestion and made the alias you posted, but now when I try do to #4 burp, I get the following.

Error number: -2147352567
Event: Execution of line 1 column 13
Description: invalid syntax

Line in error:

if 4 < 1 then
Called by: Immediate execution

Suggestion?

I mentioned above that this alias was for the Lua script language. Is your scripting language set to Lua?

I have turned my idea into a plugin, you can use this to achieve what you want:


<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE muclient>
<!-- Saved on Sunday, February 17, 2008, 2:05 PM -->
<!-- MuClient version 4.19 -->

<!-- Plugin "Repeat_Command" generated by Plugin Wizard -->

<muclient>
<plugin

   version="1.0"
   >
<description trim="y">
<![CDATA[
To use, type:

#n command

This sends "command" n times to the MUD.

For example:

#3 kick kobold
