As I said in the feature request, would love if these became natural mudlet functions.

Hm does calign respect the tags? When I use cecho(calign(...)), it's off the center.

Here's my alignment function (called "bar" because I primarily use it to display a line of text pre- and post-fixed with centering characters), which strips tags for the alignment and then reinserts them afterwards. You can probably use this to modify demonnic's code.
function bar(s,c)
local txtOnly = s:gsub("\<.+\>","")
local sLen = txtOnly:len()
local bLen = 100
local bThreshhold = math.floor(bLen / 2)
c = c or "-"
local maxWidth = 0
local function printBar(s,c)
local sLen = string.gsub(s,"\<%w+\>",""):len()
local minMaxDelta = maxWidth
local sideLen = (bLen - (sLen+4)) / 2
local side = string.rep(c,sideLen)
cecho(string.format("\n<red>%s[ <white>%s <red>]%s",side,s,side))
end
if sLen > bThreshhold then
-- Split the message, and recursively call the function again multiple times
local j = 1
while j < sLen do
local i = j
j = j + bThreshhold
j = s:find(" ",j) or j
local tmpString = s:sub(i,j)
tmpString = tmpString:gsub("^%s*(.-)%s*$", "%1") -- trim the spaces off the start and end
printBar(tmpString,c)
end
else
printBar(s,c)
end
end

Happy to help =)
I remember the night I wrote this... and I need to go back and make sure I fixed it up to respect the x/d/cecho tags.

Newly fixed up to properly calculate the string length when using color tags in the text for a [c|d|h]align() function. Slightly embarrassed I didn't catch that much much sooner, and more so it took me so long to post the fix.

New version pushed to github. Fixes issues with the color_names being used instead of colorNames.

sorry to revive such an ancient thread, but I have a question...
If I wanted to use this as part of a script, one kinda aimed towards novices to show them mudlet can be helpful and pretty, how could I go about it? Both from the perspective of easy 'installation' and also giving credit where credit is due. I don't really want to have to direct people to go to github, find the latest code, copy it into a new script and name that script "align" for safe measure. Is there a better way others would do it? Could I add it as a file within my package, with information/links to the github, BUT somehow have that not cause conflict if they already have a version of it (such as in the combined 'demonnic' pack for lusternia)
