+Terminfo Entries
+================
+
+:Author: Sebastian J. Bronner <waschtl@sbronner.com>
+:Date: 2023-02-12
+:URL: https://aur.archlinux.org/packages/st
+
+The Problem
+-----------
+
+Most Linux-based distributions will have their terminfo entries in the
+``ncurses`` package. These live in ``/usr/share/terminfo``. There you will find
+several entries for ``st``. Up until ``ncurses-6.1`` as packaged in ArchLinux,
+these, did not work well with then-current versions of ``st``.
+
+Specifically, I have observed the following issues when using the terminfo
+entries supplied with those versions of ``ncurses``:
+
+* Start ``st``.
+* Run ``tmux`` in the ``st`` window.
+* Run ``nvim`` in ``tmux``.
+
+ * ``tmux`` will crash immediately with the following message:
+
+ .. code:: console
+
+ [lost server]
+ %
+
+* Run ``w3m`` with any URL in ``tmux``.
+
+ * ``w3m`` will not react to any key presses (most notably the arrow keys and
+ ``q``) and must be terminated with ``killall w3m``.
+ * The command line returned where ``w3m`` was running will show all the
+ missing keypresses.
+
+For reference, I performed these tests using the following software versions:
+``st`` 0.8.2, ``tmux`` 2.9_a, ``neovim`` 0.4.2, and ``w3m``
+0.5.3.git20190105-1.
+
+The Workaround
+--------------
+
+The affected versions of all software packages have since been updated and the
+issue has been resolved. However, when connecting to older remote systems using
+``ssh`` in ``st``, those remote systems may still be affected. In those cases,
+it would help to copy over ``st``'s terminfo file and generate user-level
+terminfo entries:
+
+.. code:: shell
+
+ rsync /usr/share/st/st.info <remote>:
+ ssh <remote> tic -sx st.info
+
+The generated terminfo database will most likely be placed in ``~/.terminfo``.
+The command will print the actual location used. Unfortunately, these files
+need to be kept up to date by hand. Actually they should probably be removed as
+soon as a new version of ``ncurses`` is installed on the remote system.
