Subject: [PATCH] terminfo: add TS capability
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is a new ‘extended’ capability. ‘TS’ has been around for a while,
but was originally not part of foot’s terminfo. Not sure when it was
added to ncurses’ foot terminfo.

In any case, ncurses has this to say about TS:

  These building-blocks allow access to the X titlebar and icon name as a
  status line.  There are a few problems in using them in entries:

   a) tsl should have a parameter to denote the column on which to transfer to
      the status line.

   ...

  But that issue regarding the parameter for tsl means that applications may
  not rely on it.  The SVr4 documentation says tsl will "move to status line,
  column #1".  At the point in time when ESR added DJM's "pseudo-color" entry
  with the split-up escape sequence for tsl/fsl, there were 65 entries using
  tsl:
     32 used a parameter, matching the documentation (including x10term).
     21 used a parameterless control, exiting from the status line on ^M.
      6 used parameterless controls for tsl and fsl
      6 used a split-up escape sequence, e.g., the same approach.

  The extension "TS" is preferable, because it does not accept a parameter.
  However, if you are using a non-extended terminfo, "TS" is not visible.
