I searched everywhere but couldn't find a answer so I tried to make my own Read values of keys from a file and set them I havent made the set one yet but there is a problem with my reading one, It wont stop reading until another = comes.. I dont know how should I stop it in Squirrel. This is my code

function get_key(file, key)
    local r = file_readAll(file);
    local read = split(r, " = ");
    local pos = 0;
    for(pos = 0; pos < read.len(); pos++)
        if(read[pos] == key) return read[pos+1];
    return 0;

So if I read something like


So it will read it like this:


I dont want it like this, I only want it to read the value of the key not to read the name of next key with the value of the old key.. Also can I have a even better explanation and sample code or maybe you can create sorry I am still a beginner, Can anyone provide me a proper one or make it for me please.. I have been searching 13 hours.

try it this way:


function read_ini(file)
  local r=file_readAll(file);  //make sure it will read newlines!!!
  local lines = split(r, "\n"); r=null ;
  local ret={} ;
  foreach (line in lines) {
    local tmp=line.find("-") ;
    if (tmp!=false) {
        local key=strip(line.slice(0,tmp)) ;
        local val=lstrip(line.slice(tmp)) ;
        ret[key]<-val ;

local inifile=read_ini("myfile.ini") ;  //returns a TABLE with key and value according to ini file
local mykey=null ;
if ("mykey" in inifile) mykey=inifile.mykey ;

NOTE: Again, this is done by heart without really trying, so it maybe won't compile or run properly. But it shall give you an idea of how to handle the given problem:
As it seems to be an inifile, split the file into LINES first. Then search the lines for a = character, and split the line at that character manually (slice)
Create a table from the keys and values to return. Now you need to read the file ONCE and can lookup each key in the table without re-reading the file.

(I presume your read_fileAll function will return contained linefeed characters)
