I could use a \LaTeX and \XeTeX with package xltxtra, but I could not found a way to write LuaTeX or LuaLaTeX.

Is there a way to do so?

    Have a look at the hologo package. – TeXnician Dec 09 '17 at 13:17

    Just use Lua\TeX and Lua\LaTeX. – egreg Dec 09 '17 at 14:25

  • So, the answer is NO. – Rahn Dec 10 '17 at 01:04

    @Wentao The answer is YES as provided by egreg. Or if you insist on a complete macro: newcommand*{\LuaLaTex}{Lua\LaTeX} – Peter Wilson Dec 10 '17 at 18:56

    No, the answer is yes. hologo (as mentioned above) has logos for LuaTeX/LuaLaTeX (\hologo{LuaTeX}\hologo{LuaLaTeX}), they just weren't explicitly mentioned in https://tex.stackexchange.com/a/67990/. Further, the accepted answer to that question isn't up to date dtk-logos provides \luatex/\LuaTeX and \lualatex/\LualaTeX, though the packages use hologo in the definition. – Torbjørn T.

  • Okay. Not exactly what I expected, but fair enough. – Rahn Dec 11 '17 at 00:40

If you want to have the exact same logo as the one in the LuaTeX manual, you can copy the definition from the ConTeXt core file cont-log.mkiv.

It is only marginally different from Lua\TeX.

\documentclass{article}

\let\unexpanded\protected
\let\dontleavehmode\leavevmode
\newdimen\zeropoint \zeropoint=0pt

% from cont-log.mkiv
\unexpanded\def\LuaTeX
  {\dontleavehmode
   \begingroup
     Lua%
     % hope for kerning, try aT
     \setbox0\hbox{aT}%
     \setbox2\hbox{a\kern\zeropoint T}%
     \ifdim\wd0=\wd2 % kerns can go two ways
       % no aT kerning, try oT as a is not symmetrical
       \setbox0\hbox{oT}%
       \setbox2\hbox{o\kern\zeropoint T}%
       \ifdim\wd0=\wd2 % kerns can go two ways
         % no aT and oT kerning, try To
         \setbox0\hbox{To}%
         \setbox2\hbox{T\kern\zeropoint o}%
         % maybe we need to compensate for the angle (sl/it/bs/bi)
       \fi
       \ifdim\wd0=\wd2\else
         \kern\dimexpr\wd0-\wd2\relax
       \fi
     \fi
     \TeX
   \endgroup}
