在我的例子中，键似乎没有被处理...这是文件测试.cls：
\NeedsTeXFormat{LaTeX2e}[2001/06/01]
\RequirePackage{l3keys2e}
\ProvidesExplClass
{test}
{2013/12/23}
{1.0}
{Ceci est ma classe pour les cours}
\ExplSyntaxOn
\bool_new:N \mik_test_video
\keys_define:nn {montest} {
video .bool_set:N = \mik_test_video,
}
\ProcessKeysOptions{montest}
\bool_log:N \mik_test_video
\LoadClass{article}
\bool_log:N \mik_test_video
\bool_if:NTF
{\mik_test_video}
{\msg_term:n {Le~mode~vidéo~projecteur~est~ACTIVÉ}}
{\msg_term:n {Le~mode~vidéo~projecteur~est~DÉSACTIVÉ}}
\ExplSyntaxOff
\endinput
这是文件测试.tex：
\documentclass[video]{test}
\begin{document}
test2015
\end{document}
正常情况下，我应该在日志文件中看到：“Le~mode~vidéo~projecteur~est~ACTIVÉ”，但布尔值 \mik_test_video 似乎总是假的……
\bool_log:N \mik_test_video在日志中每次都得到错误。
我究竟做错了什么 ？
