| <H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE> |
| 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 |
| |
| |

| <STRONG>-T</STRONG><EM>name</EM> |
| 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. |
| |
| |
| </PRE> |
| <H3><a name="h3-Predefined-Tab-Stops">Predefined Tab-Stops</a></H3><PRE> |
| X/Open defines several predefined lists of tab stops. |
| |
| <STRONG>-a</STRONG> Assembler, IBM S/370, first format |
| |
| <STRONG>-a2</STRONG> Assembler, IBM S/370, second format |
| |
| <STRONG>-c</STRONG> COBOL, normal format |
| |
| <STRONG>-c2</STRONG> COBOL compact format |
| |
| <STRONG>-c3</STRONG> COBOL compact format extended |
| |
| <STRONG>-f</STRONG> FORTRAN |
| |
| <STRONG>-p</STRONG> PL/I |
| |
| <STRONG>-s</STRONG> SNOBOL |
| |
| <STRONG>-u</STRONG> UNIVAC 1100 Assembler |
| |
| |
| </PRE> |
| <H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE> |
| X/Open describes a <STRONG>+m</STRONG> option, to set a terminal's left- |
| margin. Very few of the entries in the terminal database |
| provide this capability. |
| |
| 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. |
