Hello,
Im trying to write something that can map a table out of a string. I have come pretty far as patterns go, but I have found one major flaw with it. First, here is the function that I wrote and the 'stringed table' Im using for test purposes.
I am printing everything out, just for test purposes. Here is the output Im getting:
As you can see, it works kinda. But Im expecting:
I know it is caused in each pattern by the last (.+). But I am unsure how to fix it properly.
If anything is unclear, please ask! And thanks for trying to help me.

Im trying to write something that can map a table out of a string. I have come pretty far as patterns go, but I have found one major flaw with it. First, here is the function that I wrote and the 'stringed table' Im using for test purposes.
The code
local function mapTable( sTable )
local strippedOf = sTable:gsub( "{%s*", "" )
:gsub( "%s*}", " " )
-- Retrieve decimal indices
local decimal = {}
for index, value in string.gmatch( strippedOf, "%[(%d+)%]%s*=%s*(.+)[,;%s]+" ) do
print( string.format( "[%s] = %s\n", tostring(index), tostring(value) ))
table.insert( decimal, { index, value })
end
-- Retrieve string indices
local String = {}
for index, value in string.gmatch( strippedOf, "([%a_]+)%s*=%s*(.+)[,;%s]+" ) do
print( string.format( "%s = %s\n", index, value ))
table.insert( String, {key, value})
end
-- Retrieve ["key"] indices
local stringBracket = {}
for index, value in string.gmatch( strippedOf, "%[[\"\'](.+)[\"\']%]%s*=%s*(.+)[,;%s]+" ) do
print( string.format( "[%q] = %s\n", index, tostring(value) ))
table.insert( stringBracket, { index, value })
end
end
mapTable( "{ [\"test\"] = \"cool\", testing = \"haha\", [1] = \"testmuch,\" }" )
I am printing everything out, just for test purposes. Here is the output Im getting:
As you can see, it works kinda. But Im expecting:
[1] = "testmuch," --# Works! :D/> Just because its the last index
testing = "haha" --# Doesnt work unfortunately
["test"] = "cool" --# Doesnt work unfortunately
I know it is caused in each pattern by the last (.+). But I am unsure how to fix it properly.
If anything is unclear, please ask! And thanks for trying to help me.
