LuaLatex: Difference between `dofile` and `require` when loading lua files

This is a small question related to the answer given here, https://tex.stackexchange.com/a/201742/17858 which computes the factorial of a number in an external lua file. 



documentclass{article}



%directlua{dofile("luatest.lua")}

directlua{require("luatest.lua")}

newcommand*{myluafact}[1]{%

  directlua{tex.write(fact(#1))}%

}

begin{document}

  test myluafact{5}

end{document}


The code for computing factorial is in luatest.lua again copied from the same link above



function fact (n)

  if n == 0 then

    return 1

  else

    return n * fact(n-1)

  end

end


The results from using dofile and require are identical on my machine for this particular example.



Is there any technical difference between loading external lua files with require or dofile in general?

          count number of partitions of a set with n elements into k subsets

          up vote 6 down vote favorite 1 This program is for count number of partitions of a set with n elements into k subsets I am confusing here return k*countP(n-1, k) + countP(n-1, k-1); can some one explain what is happening here? why we are multiplying with k? NOTE->I know this is not the best way to calculate number of partitions that would be DP // A C++ program to count number of partitions // of a set with n elements into k subsets #include<iostream> using namespace std; // Returns count of different partitions of n // elements in k subsets int countP(int n, int k) { // Base cases if (n == 0 || k == 0 || k > n) return 0; if (k == 1 || k == n) return 1; // S(n+1, k) = k*S(n, k) + S(n, k-1) return k*countP(n-1, k) + countP(n-1, k-1); } // Driver program int ma

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{
