| I was reading on how to use tables and I noticed that there is a table.concat command that strings together table values. Is there anything that does the reverse as in change:
the,quick,brown,fox,jumped
into:
t =
{
"the",
"quick",
"brown",
"fox",
"jumped",
}

| If you know the string ahead of time, you can just do:
t = {"the","quick","brown", ...}
But I'm guessing you don't know ahead of time what the string is. In that case, you should use string.gmatch:
[david@thebalrog:~]$ cat test.lua
#!/usr/bin/lua
s = "hello,world,from,Lua"
for w in string.gmatch(s, "([^,]+)") do
print(w)
end
[david@thebalrog:~]$ lua test.lua
hello
world
from
Lua
EDIT: to complete the example, instead of printing the words, you'd add them to a table using table.insert, for example. |
