Best way to set LUA_PATH? about gopher-lua HOT 4 CLOSED

Hi.

Thanks for working with GopherLua.
You can do it in much the same way as the original Lua implementation.
package.path is the path used by require to search for a GopherLua loader.

The best way that you might want is to set package.path as follows:

local script_path = _getscriptdir() -- implement in your host golang program
package.path = script_path .. [[/subdir/?.lua;]] .. package.path

from gopher-lua.

That seems sensible, thank you :)
But I'm getting this error when executing test.lua:

[G]: plugins line:1(column:1) near '�':   Invalid token

stack traceback:
    [G]: in anonymous function
    [G]: in require
    test.lua:2: in main chunk
    [G]: ?

I have a test.lua and a testmod.lua, both in the same directory.

Here's what my lua.test looks like (getCurrentDir() returns ";/absolute/path/to/script/dir"):

package.path = package.path .. getCurrentDir()
require "testmod"
print(testmod.foo())

Here's what my testmod.lua looks like:

local testmod = {}

function testmod()
    return "Hello World!"
end

return testmod

I'm new to Lua, so please excuse me if this is obvious. But from what I gather from the reference, this should load the module, right?

Thanks

from gopher-lua.

package.path = package.path .. getCurrentDir()

to

package.path = package.path .. getCurrentDir() .. [[/?.lua]]

Refer to Lua5.1 - package.loaders section for further information.

Thank you so much, I forgot about the .lua wildcard.
I'm using GopherLua to drive the plugin system of Journey now :)
