50 <STRONG>tabs</STRONG> - set tabs on a terminal
54 <H2>SYNOPSIS</H2><PRE>
55 <STRONG>tabs</STRONG> [<EM>options</EM>]] <EM>[tabstop-list]</EM>
59 <H2>DESCRIPTION</H2><PRE>
60 The <STRONG>tabs</STRONG> program clears and sets tab-stops on the termi-
61 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>
62 capabilities. If either is absent, <STRONG>tabs</STRONG> is unable to
63 clear/set tab-stops. The terminal should be configured to
71 <STRONG>General</STRONG> <STRONG>Options</STRONG>
72 <STRONG>-T</STRONG><EM>name</EM>
73 Tell <STRONG>tabs</STRONG> which terminal type to use. If this option
74 is not given, <STRONG>tabs</STRONG> will use the <STRONG>$TERM</STRONG> environment
75 variable. If that is not set, it will use the
76 <EM>ansi+tabs</EM> entry.
78 <STRONG>-d</STRONG> The debugging option shows a ruler line, followed by
79 two data lines. The first data line shows the
80 expected tab-stops marked with asterisks. The second
81 data line shows the actual tab-stops, marked with
84 <STRONG>-n</STRONG> This option tells <STRONG>tabs</STRONG> to check the options and run
85 any debugging option, but not to modify the terminal
88 <STRONG>-V</STRONG> reports the version of ncurses which was used in this
91 The <STRONG>tabs</STRONG> program processes a single list of tab stops.
92 The last option to be processed which defines a list is
93 the one that determines the list to be processed.
95 <STRONG>Implicit</STRONG> <STRONG>Lists</STRONG>
96 Use a single number as an option, e.g., "<STRONG>-5</STRONG>" to set tabs
97 at the given interval (in this case 1, 6, 11, 16, 21,
98 etc.). Tabs are repeated up to the right margin of the
101 Use "<STRONG>-0</STRONG>" to clear all tabs.
103 Use "<STRONG>-8</STRONG>" to set tabs to the standard interval.
105 <STRONG>Explicit</STRONG> <STRONG>Lists</STRONG>
106 An explicit list can be defined after the options (this
107 does not use a "-"). The values in the list must be in
108 increasing numeric order, and greater than zero. They are
109 separated by a comma or a blank, for example,
113 Use a '+' to treat a number as an increment relative to
114 the previous value, e.g.,
118 which is equivalent to the 1,6,11,16,21 example.
120 <STRONG>Predefined</STRONG> <STRONG>Tab-Stops</STRONG>
121 X/Open defines several predefined lists of tab stops.
123 <STRONG>-a</STRONG> Assembler, IBM S/370, first format
125 <STRONG>-a2</STRONG> Assembler, IBM S/370, second format
127 <STRONG>-c</STRONG> COBOL, normal format
129 <STRONG>-c2</STRONG> COBOL compact format
131 <STRONG>-c3</STRONG> COBOL compact format extended
133 <STRONG>-f</STRONG> FORTRAN
135 <STRONG>-p</STRONG> PL/I
137 <STRONG>-s</STRONG> SNOBOL
139 <STRONG>-u</STRONG> UNIVAC 1100 Assembler
143 <H2>PORTABILITY</H2><PRE>
144 X/Open describes a <STRONG>+m</STRONG> option, to set a terminal's left-
145 margin. Very few of the entries in the terminal database
146 provide this capability.
148 The <STRONG>-d</STRONG> (debug) and <STRONG>-n</STRONG> (no-op) options are extensions not
149 provided by other implementations.
151 Documentation for other implementations states that there
152 is a limit on the number of tab stops. While some termi-
153 nals may not accept an arbitrary number of tab stops, this
154 implementation will attempt to set tab stops up to the
155 right margin of the screen, if the given list happens to
