Is there a way to get caller function name?

Hey everyone,

i'm looking for a simple way to get the caller name of function for a log trace method for debugging my addons.

I tried many ways and it should not possible to get the information via "debug.getinfo". The function seems to disabled in LUA/ESO context. So is there another way to get the caller informations or 'im doing something wrong?

trigger an error and the backtrace will be shown ?

Or err() if you don't want to halt.it. ( I think that is the right function name)

I will try both, but @Ayantir your solution looks very dirty. :)

BTW you have a PM Ayantir

My method is basically the same as Ayantir's. Also, I checked and it's actually error()

All solutions does not help. I only want a debug message to chat with caller function, without anoying type the function name as string into the message. The error() function throws an assertion, wich ends into an UI error.

For example

Lua Code:

function callerFunction()
   trace()
end

will give this message into chat -> "[time] callerFunction()"

It's Lua embedded into a sandbox of a MMORPG, not Java or C#, you won't have all the fancy things.

Well, I suppose if you want to be really fancy, you can do local _, errorMessage = pcall(function()error()end) and then make a function to parse errorMessage but the simplest way is just read the error message, and if you do, you'll see 'hey this thing does give me a trace!'

Lua Code:

local function GetAddon()
    local addOn
    local function errornous() addOn = 'a' + 1 end
    local function errorHandler(err) addOn = string.match(err, "'GetAddon'.+user:/AddOns/(.-:.-):") end
    xpcall(errornous, errorHandler)
    return addOn
end

Lua Code:

...
d(GetAddon())
...

trace(message[, callback])
Prints a message and stacktrace to chat via d() or hands the array with the stacktrace to an optional callback function instead

Just saying. :rolleyes:
