Print engine name/version

Print engine name/version

[Wolfgang Schuster]

Hi Hans,

can you add command which will print the name (e.g. LuaTeX, pdfTeX ...)
and version (e.g. 0.36.0) of the current used TeX engine.

Hi Wolfgang,

I think this should better be done by a command in pdftex/luatex. The 
'Procucer' key is already set by pdftex/luatex, but sadly there is no 
access to this value for the user (although the same info is needed for 
the correspondent XMP entry in most of the PDF/X versions).
Anyhow, this is what I currently use

% extract /Producer info out of \pdftexbanner
\def\pdftexproducer
  {\ifnum\contextmarkmode=4 LuaTeX\else pdfTeX\fi % starting with luatex 
version 0.35.0 it's 'LuaTeX' with uppercase 'L' (prior versions: 'luaTeX')
   \expandafter\dopdftexproducer\pdftexbanner @@@}

\long\def\dopdftexproducer#1-#2-#3@@@%
  {-#2}

Not nice, but working (with newer luatex versions). See comment...

Best wishes,  Peter

No. All engines have multiple version commands already, I see
absolutely no need for yet another version-related primitive.

Best wishes,
Taco

I mean a command in ConTeXt, no primitive, something like this.

\def\currentenginename
  {\ifcase\texengine
   \or pdfTex%
   \or XeTeX%
   \or LuaTeX%
   \fi}

This document was produced with \currentenginename.

Can you also add \currenttexengineversion?

hm, that would be a pretty inconsistent thing, so it needs some testing

How about:

\def\currenttexengineversion
  {\ifcase\texengine
   \or\number\numexpr\pdftexversion/100.\modulonumber{100}\pdftexversion.\pdftexrevision
   \or\number\XeTeXversion\XeTeXrevision
   \or\number\numexpr\luatexversion/100.\modulonumber{100}\luatexversion.\luatexrevision
   \fi}

document: 1.40.9

well, the version macro reported version 2 (i run version 1.50) because 
you need to subtract 50 before devision; keep in mind that \numexpr does 
rounding, contrary to \divide which truncates
