Can't figure out how mod security works

[gigaturbo]

Hi,

I've got an error related to mod security in my mod and I struggle to fix it. From viewtopic.php?t=12471 I understand that I can't read files from the mod directory after the init stage. But when I try to read a directory content with

Code: Select all

local files = minetest.get_dir_list('examples', false)

in

Code: Select all

init.lua

if got the following error:

Code: Select all

ModError: Failed to load and run script from /home/blac/.minetest/mods/codeblock/init.lua:
Mod security: Blocked attempted read from examples
stack traceback:
	[C]: in function 'get_dir_list'
	/home/blac/.minetest/mods/codeblock/init.lua:15: in main chunk
Check debug.txt for details.

There's something I don't understand :'( Can you help me?

Mod security limits you to only reading and writing from certain directories

You've not provided a path to examples, so it's defaulting to whereever the working directory is. This may be somewhere like /home/blac/examples. As it's outside the Minetest directory, it blocks the read

To fix this, include either get_modpath or get_worldpath:

Code: Select all

local files = minetest.get_dir_list(minetest.get_modpath("codeblock") .. '/examples', false)

wow I forgot the path are not relative to the mod directory, thanks for your help!
