[这是更新的 \l_file_search_path_seq (expl3) 不再识别 `~` (TeX Live 2023 昨天更新)，这不是我需要问的问题。
昨天使用更新 TeX Live 2023 后tlmgr，以下代码不再起作用：
\documentclass{article}
\ExplSyntaxOn
\cs_new_protected_nopar:Nn \my_input_add:n
{
\seq_put_right:Nn \l_file_search_path_seq { #1 }
}
\cs_new_protected_nopar:Nn \my_file_input: { \file_input:n {ysgrifennu-LEARN-compact/hello} }
\cs_new_eq:NN \myinput \my_file_input:
\cs_new_eq:NN \myinputadd \my_input_add:n
\ExplSyntaxOff
\myinputadd{~/Dogfennau/Fy_Ysgrifau/dysgu/ymresymiadau}
\begin{document}
\myinput
\end{document}
具体来说，ysgrifennu-LEARN-compact/hello没有找到，
!! LaTeX Error: File 'ysgrifennu-LEARN-compact/hello' not found.
For immediate help type H <return>.
...
l.138 \myinput
~//Dogfennau/Fy_Ysgrifau/dysgu/ymresymiadau/ysgrifennu-LEARN-compact/hello.tex存在。上周，pdflatex毫不费力就找到了它。
如果我用我的主目录路径替换，则可以找到该文件。但是，早期的 TeX Live（更新前的 2023 和更早版本）不需要这样做。为了检查，我使用 TeX Live 2022 编译了相同的代码~，文件可以正常找到。~/Dogfennau/Fy_Ysgrifau/dysgu/ymresymiadaupdflatex
这是预料之中的吗？有什么方法可以恢复旧的行为吗？如果可以避免，我宁愿不对我的主目录的路径进行硬编码，因为不这样做会使事情更具可移植性。
编辑
下面是一个使用 的例子，它显示\input可以使用~，但是\myinput会失败，而使用旧版 TeX Live 都可以成功编译。
\documentclass{article}
\ExplSyntaxOn
\cs_new_protected_nopar:Nn \my_input_add:n
{
\seq_put_right:Nn \l_file_search_path_seq { #1 }

\cs_new_protected_nopar:Nn \my_file_input: { \file_input:n {ysgrifennu-LEARN-compact/hello} }

同一个例子可以pdflatex在 TeX Live 2021 和 TeX Live 2020 中成功编译。对于 TeX Live 2019，\input会失败，但如果启用语法\file_input:n，则可以编译。\usepackage{expl3}expl3
