Package Loading

In LaTeX: (no options available)

\usepackage{bxtexversion)

In plain TeX or iniTeX:

\input bxtexversion.sty

Usage

• \TeXenginename: The string of the engine name.
• \TeXengineversion: The string of the engine version.
• \TeXenginenamefull: The string of the engine name with version, in the form \TeXenginename-\TeXengineversion; if \TeXengineversion is empty then it equals to \TeXenginename.

The strings for each engine (of the latest version around 2018/10/04) is shown below:

Engine    \TeXenginename \TeXengineversion

Notices for TeX programmers

• \TeXenginename is a non-long macro which once-expands to strings of character tokens. Each character has its normal (plain-compatible) category code.
• \TeXengineversion is a non-long macro which once-expands to strings of character tokens with category code 12.
• \TeXenginenamefull is fully expandable.
