I'm still interested here... can someone tell me how to properly bring lua in scope?

Does not build yet, as lua5.2 is not found. Can someone help me? I'm not sure why it isn't found here...

It seems that wordgrinder makefile is making some assumptions about where to find lua. Setting the correct environment variables might fix the problem.

Well, now it builds but the tests do not run successfully... But I guess we can investigate a bit further now.

I also updates the package to latest master of the upstream repo, because master contains some changes to the build setup which make packaging a lot easier (IMHO). Also, the 0.6 release is old (2015) - I will update this package to a new release as soon as there is one and then follow the normal releases

If you're all okay with that.

Can someone help me here? I fail to bring lua in scope properly, it seems.

I just re-pushed the branch based on my latest master, ... and squashed the fixes.

backtrace, for the lazy:

Can someone give some love here? Maybe @ericsagnes ?

@matthiasbeyer I took a quick test at building this (v0.6).
It does find Lua lib and builds the bin by replacing your buildPhase with :

makeFlags = [
  "LUA_INCLUDE=${lua52Packages.lua}/include"
  "LUA_LIB=${lua52Packages.lua}/lib/liblua.so"
];

But then it fails running the tests (end of the Makefile) :

TEST tests/apply-markup.lua
Lua error: [string "src/lua/_prologue.lua"]:54: read from undefined local 'loadstring'
stack traceback:
        [C]: in function 'error'
        [string "src/lua/_prologue.lua"]:54: in function '__index'

error: build of ‘/nix/store/f0hmpdaam62amw10mld7cqawvwr819yc-wordgrinder-0.6.drv’ failed

I haven't tried building the latest master though.

Plus : I'm pretty sure the generic builder already set --PREFIX=$out so the installPhase may be redundant.

After watching Bryan Lunduke talk about wordgrinder, I really want this to happen here.

And I guess I'm almost there, it just does not find Xft:

Suggestions? Anyone?

This builds and runs both ncurses and X11 programs :

{ stdenv, fetchFromGitHub, pkgconfig, makeWrapper
, lua52Packages, libXft, ncurses, readline, zlib }:

stdenv.mkDerivation rec {
  name = "wordgrinder-${version}";
  version = "0.6-db14181";

  src = fetchFromGitHub {
    repo = "wordgrinder";
    owner = "davidgiven";
    rev = "db141815e8bd1da6e684a1142a59492e516f3041";
    sha256 = "1l1jqzcqiwnc8r1igfi7ay4pzzhdhss81znnmfr4rc1ia8bpdjc2";
  };
  
  makeFlags = [
    "PREFIX=$(out)"
    "LUA_INCLUDE=${lua52Packages.lua}/include"
    "LUA_LIB=${lua52Packages.lua}/lib/liblua.so"
  ];
  
  nativeBuildInputs = [ pkgconfig makeWrapper ];
  
  buildInputs = [
    libXft
    lua52Packages.lua
    ncurses
    readline
    zlib
  ];
  
  # To be able to find <Xft.h>
  NIX_CFLAGS_COMPILE = "-I${libXft.dev}/include/X11";
  
  # Binaries look for LuaFileSystem library (lfs.so) at runtime
  postInstall = ''
    wrapProgram $out/bin/wordgrinder --set LUA_CPATH "${lua52Packages.luafilesystem}/lib/lua/5.2/lfs.so";
    wrapProgram $out/bin/xwordgrinder --set LUA_CPATH "${lua52Packages.luafilesystem}/lib/lua/5.2/lfs.so";
  '';
  
  meta = with stdenv.lib; {
    description = "Text-based word processor";
    homepage = https://cowlark.com/wordgrinder;
    license = licenses.mit;
    maintainers = with maintainers; [ matthiasbeyer ];
    platforms = with stdenv.lib.platforms; linux;
  };
}

It's the latest commit before the author started using ninja-build but the program still says v0.6 once built. Hence the version name 0.6-db14181 in there.

@matthiasbeyer : you can take this and make it your own, I don't mind.
It's Sunday and I'm too lazy to push my own PR... :p

@c0bw3b I love you ❤️

I will test this out and push as soon as I tested it! Thank you very much!

It works beautifully and I can't wait to start using it! @c0bw3b ❤️

@ericsagnes @c0bw3b @falsifian ... this is still not merged? Can someone please merge this?
