Make directory path: Difference between revisions

=={{header|Lua}}==

The ubiquitous luafilesystem module contains lfs.mkdir but this does not have an option equivalent to the posix mkdir -p.

Instead, the function shown here uses package.config to determine the correct directory separator for the OS and then iterates over the path string to create each individual folder in turn.

<lang Lua>require("lfs")

function mkdir (path)

local sep, pStr = package.config:sub(1, 1), ""

for dir in path:gmatch("[^" .. sep .. "]+") do

pStr = pStr .. dir .. sep

lfs.mkdir(pStr)

end

end

mkdir("C:\\path\\to\\dir") -- Quoting backslashes requires escape sequence</lang>

Note that attempting to run lfs.mkdir for a path that already exists writes no changes to disk and returns nil.
