Question

I am trying to concat 2 strings and also append some characters to them. For example

local currdir
local node
local arg = (currdir..node)


function(arg)
etc....

but “arg” needs to have a “\” at the end of it, and be surrounded by doublequotes. So literally passed to function like “arg\”. Does anyone know how to do this? cheers

Answer 1

what about

arg = ([["%s\"]]):format(arg:gsub('\\+$',''))

This also removes any already existing trailing backslashes. For jigsawing pathnames together, you can also take a look at table.concat, and have the different pieces in a table.
