Hi, im working on version 1.0 of this script here: http://forums.warchest.com/showthread.php/32647-Communal-Mailbox-script
I am not quite up to date on the ET Lua API. Is there a way to load a config file into the Lua script. Example: i have the script commail.lua and a table in there. From another file called commail.cfg i wanna load information into that table, is it possible somewhat easy or are there examples out there showing how to do this?
There are couple of luas which read stuff from files:
http://mnwa.bplaced.net/ftpfiles/Lua/kspree.lua
http://mnwa.bplaced.net/ftpfiles/Lua/randomspawn.lua
http://mnwa.bplaced.net/ftpfiles/Lua/seen.lua

You are in need of “pattern” then.
for example this line:
for name, guid, password in string.gfind(content_file, “([^
]+) (%w+) (%w+)”) do
I wrote some simple iterator to fetch all keys and values from et config like files: (key “value” etc)
I don’t know if this is what you wanted tho, but here are sample usage and code:
Usage (should be used in for loop):
-- use it in for loop to fetch all keys and values
for [B]key[/B], [B]value [/B]in [I]readconfig [/I][B]"sample.cfg"[/B] do
-- you can fill your table here as well as do some value check
configTable [[B]key[/B]] = [B]value[/B]
end
function readconfig (fileName)
fd, len = et.trap_FS_FOpenFile(fileName, et.FS_READ)
if len ~= -1 then
filedata = et.trap_FS_Read(fd, len)
end
et.trap_FS_FCloseFile(fd)
if not filedata then return nil end
local lines = string.gmatch(filedata, "[^
]+")
local i = 0
-- basic iterator + line iterator
return function ()
while true do
local key, value = parseConfig ( lines (i + 1) )
-- skipping empty strings ...
if key then
if key ~= "" then
return key, value
end
else
return nil
end
end
end
end
function parseConfig (line)
if not line then return nil end
-- lets clean double slash comment, "set" and "exec" keywords
line = line :gsub ("//.+", "")
:gsub ("^%s*set%s+", "")
:gsub ("^%s*exec%s+.+", "")
:gsub ("^%s*(.-)%s*$", "%1") -- trim string
-- skip
if line == "" then return "" end
local key, value = line:match "([%w_]+)%s+(.+)"
if key and value then
local temp = tonumber (value)
if temp then
return key, temp
else
temp = value:match "^\"(.+)\"$"
-- all string values should be enclosed with quotes
if temp then
-- trying to conver "16" string numbers into numbers
value, temp = temp, tonumber (temp)
if temp then
value = temp
end
return key, value
elseif value == '""' then
-- empty values
return key, ""
end
end
end
return ""
end
