Formatting (e.g. title case, lower case, etc.)

[Alexander Divine]

I migrated from zMud and so I'm a little spoiled.

What I want is a way to convert a string to proper/title case, or all uppercase, or any number of things.

I'm pretty much writing a function to do this right now, but is there an existing one? If so, I'm gonna slap myself.

not sure what you mean by titlecase, unless you mean First Letter Of Every Word Capitalized


as for all upper and all lowercase, I would suggest string.upper() and string.lower() as perhaps the best answer

also, for title case, I found the following function online, which may be useful:

Code: Select all

function titlecase(str)
    local buf = {}
    for word in string.gfind(sel, "%S+") do          
        local first, rest = string.sub(word, 1, 1), string.sub(word, 2)
        table.insert(buf, string.upper(first) .. string.lower(rest))
    end    
    return table.concat(buf, " ")
end

this was found at http://lua-users.org/wiki/StringRecipes

You guys are fantastic. This'll save me a ton of time.

For anyone interested, some ultra-easy functions to make text formatting simple.

Code: Select all

function title(str)
  str = str:gsub("^%l", string.upper, 1)
  return str
end

function upper(str)
  str = string.upper(str)
  return str
end

function lower(str)
  str = string.lower(str)
  return str
end

Actually, here's a miscellaneous question: for the title-case string above, I added a return and it pretty much worked without incident: can anyone break down exactly what str:gsub means?

I don't quite get the point of last two functions, but for capitalization, we'll have this added soon:

I like shortcuts, what can I say.

Well you made it be for example echo(upper(variable)) when echo(variable:upper()) did the same thing without having that
