Terminfo Entries
|
||||
================
|
||||
|
||||
:Author: Sebastian J. Bronner <waschtl@sbronner.com>

|
||||
|
||||
The Problem
|
||||
-----------
|
||||
|
||||
Most Linux-based distributions will have the bulk of their terminfo entries in
|
||||
the ``ncurses`` package. These live in ``/usr/share/terminfo``. There you will
|
||||
find several entries for ``st``. These, however, do not work well with current
|
||||
versions of ``st``. You need the terminfo entries supplied with ``st``.
|
||||
|
||||
Specifically, I have observed the following issues when using the terminfo
|
||||
entries supplied with ``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 Solution
|
||||
------------
|
||||
|
||||
The ``ncurses`` package should stop shipping terminfo entries for ``st``. These
|
||||
should then be provided in ``/usr/share/terminfo`` by this (and other) ``st``
|
||||
packages. The conflicting terminfo entries are
|
||||
|
||||
* ``st`` and
|
||||
* ``st-256color``.
|
||||
|
||||
Additional entries that could be considered for removal from ``ncurses`` are
|
||||
|
||||
* ``st-0.6``,
|
||||
* ``st-0.7``,
|
||||
* ``st-16color``,
|
||||
* ``st-direct``,
|
||||
* ``stterm`` (for distributions that rename ``st`` to ``stterm``),
|
||||
* ``stterm-16color``, and
|
||||
* ``stterm-256color``.
|
||||
|
||||
This solution cannot be implemented without the cooperation of ``ncurses``
|
||||
since many distributions (including Arch Linux) do not allow for two packages
|
||||
that provide files with identical paths to be installed side-by-side.
|
||||
Therefore, I am bringing this to the attention of the ``ncurses`` team.
|
||||
|
||||
The Workaround
|
||||
--------------
|
||||
|
||||
A somewhat painful, albeit pragmatic, workaround is as follows: A user that
|
||||
encounters issues that are due to mismatched terminfo entries, such as those
|
||||
above, can symlink the terminfo entries included in this package into her
|
||||
user-level terminfo database using the following commands:
|
||||
|
||||
.. code:: shell
|
||||
|
||||
mkdir ~/.terminfo/s
|
||||
ln -s /usr/share/st/terminfo/s/* ~/.terminfo/s
