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``.

Most Linux-based distributions will have their terminfo entries in the

these, do not work well with current versions of ``st``.

||||
0.5.3.git20190105-1.
|
||||
|

A couple of issues have been filed against ``tmux`` for this. Although it is
|
||||
not a problem with ``tmux`` the issues remain for reference:

|
||||
|
||||
Complications
|
||||
-------------
|
||||
|
||||
While it may be tempting to use the terminfo files shipped with ``st``, that
|
||||
would be a bad idea from a packaging standpoint. There are two reasons for
|
||||
this: (1) As of ``st-0.8.2`` they have errors in them. This has been fixed and
|
||||
will roll out in the next release, though.
|
||||
|
||||
| https://lists.gnu.org/archive/html/bug-ncurses/2019-10/msg00071.html
|
||||
| https://lists.suckless.org/hackers/1911/17006.html
|
||||
|
||||
(2) It is vital that remote terminals connecting via ``ssh`` are known. That is
|
||||
accomplished by having all terminfo files in one package (like ``ncurses``).
|
||||
|
||||
``ncurses`` has released updated terminfo entries. The problem as described
|
||||
above is fixed. However, the updated terminfo entries are not installed on
|
||||
ArchLinux because they were released as a standalone file without a new release
|
||||
of the rest of ``ncurses``.
|
||||
|
||||
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
|
||||
The solution must be to get the updated terminfo entries packaged for
|
||||
ArchLinux. I believe that the ``ncurses`` package should be updated to that
|
||||
effect.
|
||||
|
||||
* ``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:
|
||||
above, can populate a user-level terminfo database from the terminfo entries
|
||||
supplied by ``st``. The following command will do this:
|
||||
|
||||
.. code:: shell
|
||||
|
||||
mkdir ~/.terminfo/s
|
||||
ln -s /usr/share/st/terminfo/s/* ~/.terminfo/s
|
||||
tic -sx /usr/share/st/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 released.
