string patterns, split sets of strings into various tables? [closed]
ok this topic confuses me
how would i make a string pattern that gets every digit & uppercase or lowercase letter or whitespace and puts the string into a table. if it finds a specific character then it stops, then gets the position of the character that was found and continues off putting strings after that character into a different table
for example character to find is '|'
"1dsi,gok cnmx| do46,d"
table 1 = {"1dsi", "gok cnmx"}
table 2 = {" do46", "d"}
i did this at first
for Word in string.gmatch(Message, "(%w*%s*),*|?") do
table.insert(SortedMessage, Word)
end
and for that, the output for
"1ad, fds h4 o |as56"
is
{"1ad", " fds h4 o ", "as56"}
i just have no idea how to split the rest of the groups into a different table after '|', and another one if it finds another after, etc
i tried to split it into groups but i failed miserably, heres my attempt on that
SortMessageToTable = function(Message)
local SortedMessage = {
}
local CurrentTable = {}
for w,i in string.gmatch(Message, "(%w*),*()") do
table.insert(CurrentTable, w)
print(w)
if Message:sub(i, i) == "|" then
table.insert(SortedMessage, CurrentTable)
CurrentTable = {}
end
end
table.insert(SortedMessage, CurrentTable)
return SortedMessage
end
and this is what i get for this mess: http://i.imgur.com/kazWUry.gifv
also, here's the code that reads the returned table
local SortedMessage = Commands.SortMessageToTable(Message)
for i=1, #SortedMessage do
for v=1, #SortedMessage[i] - 1 do
print(i, SortedMessage[i][v])
end
end
help would be appreciated

If I understand you right, you want to split into groups by |, and then split those into groups by ,.
For example, "ab,cd|e|f,g,h" should be mapped to {{"ab", "cd"}, {"e"}, {"f", "g", "h"}}.
In that case, just first split by "|" and then split each by ",":
-- EXAMPLE:
-- splitString("foo||bar", "|") returns {"foo", "", "bar"}
function splitString(str, by)
local out = {}
for word in (str .. by):gmatch("(.-)" .. by) do
table.insert(out, word)
end
return out
end
local input = "1dsi,gok cnmx| do46,d"
local splitBar = splitString(input, "|")
for i = 1, #splitBar do
splitBar[i] = splitString(splitBar[i], ",")
end
