From 44f5fb3275bd88f730b28a4c19ec9a83e3591806 Mon Sep 17 00:00:00 2001 From: Juergen Spitzmueller Date: Thu, 17 Oct 2024 09:55:31 +0200 Subject: [PATCH] Improve version test in chkconfig This now only loads the package until it has the version information and then ends the package input. This way, we do not need to care about package peculiarities (having to be loaded after \documentclass or internal dependencies which, if not given, might break the whole configuration, see #13112) --- lib/chkconfig.ltx | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/lib/chkconfig.ltx b/lib/chkconfig.ltx index 41b7412d2e..bf0d410fd5 100644 --- a/lib/chkconfig.ltx +++ b/lib/chkconfig.ltx @@ -60,11 +60,6 @@ % the variable chk_. %%% -% we need to load the minmal class -% since some packages will error out -% on checking of no class is loaded -\documentclass{minimal} - \newcommand{\prefix}{+} % the character used by grep to filter 'good' output \newcommand{\AddLayout}[5][\default]{ @@ -125,12 +120,22 @@ #6 \fi} + +% For the version test below, we need to load the tested package. +% However, we are only interested in the version information, so +% we redefine an internal method of \ProvidesPackage to quit +% as soon as we have that information +\let\chk@pr@videpackage\@pr@videpackage +\def\@pr@videpackage[#1]{\chk@pr@videpackage[#1]\endinput} + % Tests whether an package is present and also adds the version to the package list \newcommand{\TestPackageAddVersion}[2][\default]{ \def\default{#2} \def\package@version{} - % The actual test only works after the package has been loaded \IfFileExists{#1.sty}{% + % The actual test only works after the package has been loaded, + % but with the redefinition of \@pr@videpackage above, we quit + % as early as possible \RequirePackage{#1}% \protected@edef\package@@version{\csname ver@#1.sty\endcsname}% \protected@edef\package@version{\expandafter\@parse@version\package@@version//00\@nil}%
