help with modules

[LollipopFt]

hi, I have this module with filename lineguides.lua:

for _, i in ipairs(_G.guides) do
    _G.view:multi_edge_add_line(i, 0x808080)
end

_G.view.edge_mode = view.EDGE_MULTILINE

and have this in my init.lua:

_G.guides = {80, 100}

to get line guides at the specified columns. however, i see other plugins using something like

local M = {}
M.guides = {}

and their init.lua file with

[module name].guides = {80, 100)

and getting values from there. i have tried using that but failed so may i know how this can be achieved since i do not want to use global(_G) variables? thank you!

I think the following should work:

lineguide.lua

local M = {}

M.guides = {}

events.connect(events.INITIALIZED, function()
  for _, i in ipairs(M.guides) do
      view:multi_edge_add_line(i, 0x808080)
  end

  view.edge_mode = view.EDGE_MULTILINE
end)

return M

init.lua

local lineguide = require("lineguide")
lineguide.guides = {80, 100}

The return M makes the modules variables available when you import it. Since the guides variable is not set when you require the module the edge setting is postponed until the initialization finishes.
