CTAN update: iftex
Date: November 10, 2019 8:41:07 PM CET
The LaTeX Team submitted an update to the
iftex
package.
Version number: 1.0c
License type: lppl1.3c
Summary description: Am I running under pdfTeX, XeTeX or LuaTeX?
Announcement text:
Update to iftex with no change to the user interface but internal tests now treat \relax like undefined when testing for the existence of engine-specific commands. So for example \ifxetex is set to false if \XeTeXrevision is undefined or if it is defined to be \relax.
This package is located at http://mirror.ctan.org/macros/latex/contrib/iftex More information is at https://www.ctan.org/pkg/iftex
Thanks for the upload. For the CTAN Team Manfred Lotz CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs .

iftex – Am I running under pdfTeX, XeTeX or LuaTeX?
The package, which works both for Plain TeX and for LaTeX, defines the \ifPDFTeX, \ifXeTeX, and \ifLuaTeX conditionals for testing which engine is being used for typesetting.
The package also provides the \RequirePDFTeX, \RequireXeTeX, and \RequireLuaTeX commands which throw an error if pdfTeX, XeTeX or LuaTeX (respectively) is not the engine in use.
