+ fix errata for ncurses-howto (report by Damien Ruscoe). + fix a few places in configure/build scripts where DESTDIR and rpath were combined (report by Thomas Klausner). + merge current st description (report by Harry Gindi) -TD + modify flash capability for linux and wyse entries to put the delay between the reverse/normal escapes rather than after -TD + modify program tabs to pass the actual tty file descriptor to setupterm rather than the standard output, making padding work consistently. + explain in clear's manual page that it writes to stdout. + add special case for verbose debugging traces of command-line utilities which write to stderr (cf: 20161126). + remove a trace with literal escapes from skip_DECSCNM(), added in 20161203. + update config.guess, config.sub from http://git.savannah.gnu.org/cgit/config.git

|
|
The <STRONG>tabs</STRONG> program clears and sets tab-stops on the termi-
|
|
nal. This uses the terminfo <EM>clear</EM><STRONG>_</STRONG><EM>all</EM><STRONG>_</STRONG><EM>tabs</EM> and <EM>set</EM><STRONG>_</STRONG><EM>tab</EM>
|
|
capabilities. If either is absent, <STRONG>tabs</STRONG> is unable to
|
|
clear/set tab-stops. The terminal should be configured to
|
|
use hard tabs, e.g.,
|
|
|
|
stty tab0
|
|
|
|
Like <STRONG><A HREF="clear.1.html">clear(1)</A></STRONG>, <STRONG>tabs</STRONG> writes to the standard output. You
|
|
can redirect the standard output to a file (which prevents
|
|
<STRONG>tabs</STRONG> from actually changing the tabstops), and later <STRONG>cat</STRONG>
|
|
the file to the screen, setting tabstops at that point.

|
|
Tell <STRONG>tabs</STRONG> which terminal type to use. If this option
|
|
is not given, <STRONG>tabs</STRONG> will use the <STRONG>$TERM</STRONG> environment
|
|
variable. If that is not set, it will use the
|
|
<EM>ansi+tabs</EM> entry.
|
|
|
|
<STRONG>-d</STRONG> The debugging option shows a ruler line, followed by
|
|
two data lines. The first data line shows the
|
|
expected tab-stops marked with asterisks. The second
|
|
data line shows the actual tab-stops, marked with
|
|
asterisks.
|
|
|
|
<STRONG>-n</STRONG> This option tells <STRONG>tabs</STRONG> to check the options and run
|
|
any debugging option, but not to modify the terminal
|
|
settings.
|
|
|
|
<STRONG>-V</STRONG> reports the version of ncurses which was used in this
|
|
program, and exits.
|
|
|
|
The <STRONG>tabs</STRONG> program processes a single list of tab stops.
|
|
The last option to be processed which defines a list is
|
|
the one that determines the list to be processed.
|
|
|
|
|
|
</PRE><H3><a name="h3-Implicit-Lists">Implicit Lists</a></H3><PRE>
|
|
Use a single number as an option, e.g., "<STRONG>-5</STRONG>" to set tabs
|
|
at the given interval (in this case 1, 6, 11, 16, 21,
|
|
etc.). Tabs are repeated up to the right margin of the
|
|
screen.
|
|
|
|
Use "<STRONG>-0</STRONG>" to clear all tabs.
|
|
|
|
Use "<STRONG>-8</STRONG>" to set tabs to the standard interval.
|
|
|
|
|
|
</PRE><H3><a name="h3-Explicit-Lists">Explicit Lists</a></H3><PRE>
|
|
An explicit list can be defined after the options (this
|
|
does not use a "-"). The values in the list must be in
|
|
increasing numeric order, and greater than zero. They are
|
|
separated by a comma or a blank, for example,
|
|
|
|
tabs 1,6,11,16,21
|
|
tabs 1 6 11 16 21
|
|
|
|
Use a "+" to treat a number as an increment relative to
|
|
the previous value, e.g.,
|
|
|
|
tabs 1,+5,+5,+5,+5
|
|
|
|
which is equivalent to the 1,6,11,16,21 example.

IEEE Std 1003.1/The Open Group Base Specifications Issue
|
|
7 (POSIX.1-2008) describes a <STRONG>tabs</STRONG> utility. However
|
|
|
|
<STRONG>o</STRONG> This standard describes a <STRONG>+m</STRONG> option, to set a termi-
|
|
nal's left-margin. Very few of the entries in the
|
|
terminal database provide this capability.
|
|
|
|
<STRONG>o</STRONG> There is no counterpart in X/Open Curses Issue 7 for
|
|
this utility, unlike <STRONG>tput(1)</STRONG>.
|
|
|
|
The <STRONG>-d</STRONG> (debug) and <STRONG>-n</STRONG> (no-op) options are extensions not
|
|
provided by other implementations.
|
|
|
|
Documentation for other implementations states that there
|
|
is a limit on the number of tab stops. While some termi-
|
|
nals may not accept an arbitrary number of tab stops, this
|
|
implementation will attempt to set tab stops up to the
|
|
right margin of the screen, if the given list happens to
|
|
be that long.
