Getting to Know Lua's lfs Module
Programmers can access a variety of useful functions for managing files and directories with the Lua lfs module.
Listing Files
Using Lua's lfs module to list files in a directory is simple. Let's investigate the process.
-- Example: Listing files in a directory using lfs
local lfs = require("lfs")
local dir_path = "/path/to/directory"
for file in lfs.dir(dir_path) do
if file ~= "." and file ~= ".." then
print(file)
end
end
Output:
file1.lua
file2.txt
subdirectory
Exploring Directories
Using Lua's lfs module to navigate around directories is like navigating a maze - but with a map. Take a look at this example to see how to do it.
-- Example: Navigating through directories using lfs
local lfs = require("lfs")
local function explore_directory(directory)
for file in lfs.dir(directory) do
if file ~= "." and file ~= ".." then
local file_path = directory .. "/" .. file
print(file_path)
if lfs.attributes(file_path, "mode") == "directory" then
explore_directory(file_path)
end
end
end
end
explore_directory("/path/to/root/directory")
Output:
/path/to/root/directory/file1.lua
/path/to/root/directory/file2.txt
/path/to/root/directory/subdirectory
/path/to/root/directory/subdirectory/file3.lua
Conclusion
Lua lfs module is like a reliable ally that helps you handle file-related tasks with ease.
