回复：list files in dir recursively

["R.wen" <rwen2012@...>]

or this one maybe more close as you want,

local function listfile(dir)
 local fpl = {}
 for entry in lfs.dir(dir) do
  if entry ~= "." and entry ~= ".." then
   local ne =  dir..'\\'..entry
   if lfs.attributes(ne).mode == "directory" then
    local p = listfile(ne, fpl)
    table.move(p, 1, #p, #fpl+1, fpl)
   else --file
    fpl[#fpl + 1] = ne
   end
  end
 end
 return fpl
end

local list = listfile(dir, fpl)
for _, n in pairs(list) do
 print(n)
end

how about this version?

local function listfile(dir, fpl)
 for entry in lfs.dir(dir) do
  if entry ~= "." and entry ~= ".." then
   local ne =  dir..'\\'..entry
   if lfs.attributes(ne).mode == "directory" then
    listfile(ne, fpl)
   else --file
    fpl[#fpl + 1] = ne
   end
  end
 end
end

local fpl = {}
listfile(dir, fpl)

for _, n in pairs(fpl) do
 print(n)
end

主题: list files in dir recursively

Hi guys,

Here is a function that finds all files in nested dirs and returns a table of file paths. I can't figure out how to keep the table variable inside the function. For example.

require 'paths'

require 'lfs'

fpaths = {}

function isdir(path)

  return lfs.attributes(path)["mode"] == "directory"

end

function listfiles(dir)

  local files = paths.dir(dir)

  for i=1,#files do

    if files[i] ~= '.' and files[i] ~= '..' then

      next_dir = dir..'/'..files[i]

      if isdir(next_dir) then

        listfiles(next_dir)

      else

        table.insert(fpaths,files[i])

      end

    end

  end

  return fpaths

end

If I include fpaths inside listfiles it will be overwritten with each new recursive call. I tried to create a closure but I think I just do not understand how they work in lua.

Can somebody help me out with this?

Best,

Pavel
