Re: [Dev-luatex] Importing .tex files using \directlua to navigate files and folders

      ...
Hi all,
I've been trying to import all tex files and inside a given folder, the
issue I'm facing is that my lua call is not able to navigate folders: it
only works for files.
It's worth mentioning that compilation successfully completes as the
document is created, but I have no errors explaining me why it's not
working as intended.
I've also opened a question on tex.stackexchange.
would you mind having a look at it ?

Not really a question for this list but anyway ... you can't nest a

dirctory scan (has to do with states and handles outside our scope) so 
you need to collect. I patched your code:

function inputAll(dir)
     local allFiles = { }
     local allDirs = { }
     local function isTexFile(dirOrFolder)
         return string.find(dirOrFolder, ".+%.tex")
     end
     local function collectSome(m)
         for content in lfs.dir(m) do
             if ("." ~= content) and (".." ~= content)  then
                 local fullpath = m .."/".. content
                 local contentType = lfs.attributes(fullpath, "mode")
                 if contentType == "file" then
                     if isTexFile(content) then
                         table.insert(allFiles, fullpath)

             end
         end
     end
     collectSome(dir)
     for i, name in ipairs(allDirs) do
         collectSome(name)
     end
     table.sort(allFiles)
     for i, name in ipairs(allFiles) do
         print(name)
     end
end

or something like that (warning for context users: we have better ways 
than this)
