Mudlet features and API requests

[Lezard]

I recently found this: http://rainbowcoding.com/how-to-create- ... avascript/
And I was wondering if you could make a Mudlet function to make text rainbow colored Is this possible?

You can do this in lua. Just have a rainbowecho() function or whatever. The arguments would be your starting point/end point, and word. Then just divide your RGB spectrum defined by your gradient range by your word length.

Something like this (written in a browser, so it probably won't work and some functions might not exist as they're written . Also, change end to something that isn't a reserved name. You can do the same if you want to change the background too)

Code: [show] | [select all] lua

function rainbowecho(start,end,word)
 --get your range
 local red = end[1]-start[1]
 local green = end[2]-start[2]
 local blue = end[3]-start[3]
 local increment = (abs(red)+abs(green)+abs(blue))/length(word)
 for i,letter in pairs(word) do
  decho(letter, start[1]..","..start[2]..","..start[3],"0,0,0")
  local cindex = 1
  local iamt=increment
  while cindex<3 and iamt do
    if start[cindex]<255 then
      local imax = 255-start[cindex]
      if imax>iamt then
         start[cindex]=start[cindex]+iamt
      else
         iamt=iamt-255-start[cindex]
         start[cindex]=255
      end
      cindex=cindex+1
    end
  end
 end
end
rainbowecho({255,125,0},{255,255,0},"this is a test")

o.O

I prefer to simplify basic things like this personally. How about:

Code: [show] | [select all] lua

function rainbow(args)
	local str = ""
	local colours = { "<red>", "<green>", "<blue>", "<yellow>", "<orange>", "<cyan>" }

	for char in args:gmatch"." do
		str = str .. colours[math.random(#colours)] .. char
	end

	return cecho(str)
end

?

Alternative method. (Just change the colours as required.)

Code: [show] | [select all] lua

function rainbow(args)
	local str = ""
	local colours = { "<red>", "<orange>", "<yellow>", "<green>", "<blue>", "<blue_violet>", "<DarkViolet>" }
	local pass = 1

	for char in args:gmatch"." do
		str = str .. colours[pass] .. char
		if pass == #colours then pass = 1 end
		pass = pass + 1
	end

	return cecho(str)
end

Thanks Chris, and Phasma! Let's say I wanted to use string.format() on it, how would I go about getting this code to work:

Code: [show] | [select all] lua

function rainbow(args, ...)
        local str = ""
        local colours = { "<red>", "<orange>", "<yellow>", "<green>", "<blue>", "<blue_violet>", "<DarkViolet>" }
        local pass = 1

        for char in args:gmatch"." do
                str = str .. colours[pass] .. char
                if pass == #colours then pass = 1 end
                pass = pass + 1
        end

        return cecho(string.format(str, (...)))
end

Basically, what I'm trying to accomplish is something like this:
rainbow("This is a %s", "Test")

Thanks!

It really depends on what you want to format it to, although simply doing:

Code: [show] | [select all] lua

return cecho(string.format("%s", str))

Will ensure it gets formatted as a string.

[Lezard]

I also did this, and it seems to work nicely..

Code: [show] | [select all] lua

function sys.echo(...)
	cecho(rainbow(string.format(...)))
end

A function to check if the selection is underlined/bold/italic would be nice - useful in scripts.

How about extended IRC support? An idea we've been throwing around on a MUSH I play is how cool it would be to have a sub-channel for scripts, like in WoW, that talk to one another for various networking purposes. Implementing better IRC functionality in Mudlet would make this very possible.

Would be nice to have events for when installing packages either through the gui or the new function. One for erroring and another for success.

Also, the ability to give a profile argument to the connect and disconnect functions.
