ifptex Package ― Test for p engine

Package Loading

In plain :

\input ifptex.sty

In :

\usepackage{ifptex}

Usage

NB: Here “-ness” is not considered.

  • \ifptex (or \ifpTeX) if-token Whether the engine is p (including up or p-ng).
    • \ifstrictptex (or \ifstrictpTeX) if-token Whether the engine is p but not up or p-ng.
    • \ifuptex (or \ifupTeX) if-token Whether the engine is up (including p-ng).
    • \ifstrictuptex (or \ifstrictupTeX) if-token Whether the engine is up but not p-ng.
    • \ifnativeuptex (or \ifnativeupTeX) if-token Whether the engine is up and its internal encoding is Unicode.
    • \ifptexng (or \ifpTeXng) if-token Whether the engine is p-ng.
    • \RequirepTeX Issues an error if \ifpTeX fails.
    • \RequireStrictpTeX Issues an error if \ifstrictpTeX fails.
    • \RequireupTeX Issues an error if \ifupTeX fails.
    • \RequireStrictupTeX Issues an error if \ifstrictupTeX fails.
    • \RequireNativeupTeX Issues an error if \ifnativeupTeX fails.
    • \RequirepTeXng Issues an error if \ifpTeXng fails.
    • \upTeXguessedversion mathchardef-token The guessed value of up version; given as a 100-folded integer. NB. On version 1.23 or later, the value is correct. NB. On a non-up engine, the value is zero.
    • \RequireupTeXAtLeast{<required>} Issues an error if \upTeXguessedversion is smaller than the given required value.
    • \RequireNativeupTeXAtLeast{<required>} Issues an error either if \upTeXguessedversion is smaller than the given required value or if \ifnativeupTeX fails.

ifuptex Package ― Alias of ifptex

The ifuptex package does nothing but loading ifptex internally. It is provided for backward compatibility.

Package Loading

In plain :

\input ifuptex.sty

In :

\usepackage{ifuptex}

Usage

Just the same as the ifptex package.
