Haskell: Converting a .lua table to Haskell workable types
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I'm a beginner trying to practice coding haskell by translating some simple repo from different languages to Haskell.
Many simple games use .lua to store character/ability data.
What I want is to take that .lua table and convert it into haskell workable types.
This is what the .lua file looks like
local Data =
{
["Weapons"] = {
["AB"] = {
Name = "AB",
Cost = {
Spells = 65000,
BCost = 15000,
MCost = 150,
sh = 35,
Time = 24,
Parts = {
{ Name = "Top",Type = "Item",Count = 1,},},
},
Resist = 0.85,
Class = "Shield",
Attack = {
Damage = {
["First"] = 5,
["Second"] = 5,
["Third"] = 40,},
Chance = 0.2,
X = 2,
},
},
["PG"] = {
...
...
...
}
return Data
When woking with Aeson, there's this simple function decode which you can use as decode someJSON :: Maybe Object and get the entirety of JSON file content put in default Aeson datatypes which you can work on with library functions. I haven't been able to find something similar for .lua.

You may check hslua-aeson package. It seems to have instances to push and receive Aeson's Value type to and from the Lua stack.

@Redu From its README.md it seems like the package does JSON to Lua. Is converting Lua to JSON possible with that package?

@Redu This is what I triedmain = do openlibs dofile "src/configfile.lua" wData <- getglobal "Data" *> peek (-1) liftIO $ print (wData :: Value)after removinglocalfrom the.luafile.

Sorry.. i have no experience with Lua - Haskell workflow at all. It was just an idea. Have you tried going through the code?

No worries! The code you linked does seem to convert Lua table values to Haskell inPeekableinstance. It might just work! I'll just need to work out how it operates.
