Each part contains text (a "string") 125 1.1 christos that identifies some aspect of the document as a whole. 126 1.1 christos <p> 127 1.1 christos The left part ("header left") lines up with the document's 128 1.1 christos left margin. The centre part ("header centre") is 129 1.1 christos centred on the document's line length. The right part ("header 130 1.1 christos right") lines up with the document's right margin. Not all parts 131 1.1 christos need contain a string, and if you don't want headers at all, you can 132 1.1 christos turn them off completely. 133 1.1 christos <p> 134 1.1 christos <strong>A note to groff experts:</strong> Although 135 1.1 christos <strong>mom</strong>'s headers resemble the three-part titles generated 136 1.1 christos by <code>.tl</code>, they're in no way related to it, nor based 137 1.1 christos upon it. <code>.tl</code> is not used at all in <strong>mom</strong>. 138 1.1 christos <p> 139 1.1 christos Normally, <strong>mom</strong> fills headers with strings appropriate 140 1.1 christos to the document type selected with 141 1.1 christos <a href="docprocessing.html#DOCTYPE">DOCTYPE</a>. 142 1.1 christos You can, however, supply whatever strings you like -- including page 143 1.1 christos numbers -- to go in any part of headers. What's more, you can set the 144 1.1 christos family, font, size and capitalization style (caps or caps/lower-case) 145 1.1 christos for each header part individually. 146 1.1 christos <p> 147 1.1 christos By default, <strong>mom</strong> prints a horizontal rule beneath 148 1.1 christos headers to separate them visually from running text. In the case of 149 1.1 christos footers, the rule is <em>above</em> running text. You can increase 150 1.1 christos or decrease the space between the header and the rule if you like (with 151 1.1 christos <a href="#HDRFTR_RULE_GAP">HEADER_RULE_GAP</a>), 152 1.1 christos or remove it completely. 153 1.1 christos <p> 154 1.1 christos 155 1.1 christos <a name="HEADER_STYLE"><h3><u>Default specs for headers/footers</u></h3></a> 156 1.1 christos <p> 157 1.1 christos <strong>Mom</strong> makes small type adjustments to each part of 158 1.1 christos the header (left, centre, right) to achieve an aesthetically 159 1.1 christos pleasing result. The defaults are listed below. (The strings 160 1.1 christos <strong>mom</strong> puts by default in each part are explained in 161 1.1 christos <a href="docprocessing.html#DOCTYPE">DOCTYPE</a>.) 162 1.1 christos <p> 163 1.1 christos <strong>NOTE:</strong> Except for capitalization (all caps or 164 1.1 christos caps/lower-case), these defaults apply only to 165 1.1 christos <a href="docprocessing.html#PRINTSTYLE">PRINTSTYLE TYPESET</a>. 166 1.1 christos <p> 167 1.1 christos <pre> 168 1.1 christos TYPE SPEC HEADER LEFT HEADER CENTER HEADER RIGHT 169 1.1 christos --------- ----------- ------------- ------------ 170 1.1 christos Family document default document default document default 171 1.1 christos Font roman italic roman 172 1.1 christos Colour (black) (black) (black) 173 1.1 christos All caps no no yes 174 1.1 christos Size* -.5 (points) -.5 (points) -2 (points) 175 1.1 christos (-2 if all caps) (-2 if all caps) (-.5 if not all caps) 176 1.1 christos 177 1.1 christos *Relative to the point size of type in paragraphs 178 1.1 christos </pre> 179 1.1 christos 180 1.1 christos You can, of course, change any of the defaults using the appropriate 181 1.1 christos control macros. And should you wish to design headers from the ground 182 1.1 christos up, <strong>mom</strong> has a special macro, 183 1.1 christos <a href="#HDRFTR_PLAIN">HEADER_PLAIN</a>, 184 1.1 christos that removes all type adjustments to headers. The straightforward 185 1.1 christos type specs for paragraphs are used instead, providing a simple 186 1.1 christos reference point for any alterations you want to make to the family, 187 1.1 christos font, size and capitalization style of any header part. 188 1.1 christos <p> 189 1.1 christos 190 1.1 christos <a name="VERTICAL_SPACING"><h3><u>Vertical placement and spacing of headers/footers</u></h3></a> 191 1.1 christos <p> 192 1.1 christos As explained in the section on 193 1.1 christos <a href="typedocmac.html">typesetting macros in document processing</a>, 194 1.1 christos the top and bottom margins of a <strong>mom</strong> document 195 1.1 christos are the vertical start and end positions of 196 1.1 christos <a href="definitions.html#TERMS_RUNNING">running text</a>, 197 1.1 christos not the vertical positions of headers or footers, which, by definition, 198 1.1 christos appear in the margins <em>above</em> (or below) running text. 199 1.1 christos <p> 200 1.1 christos The vertical placement of headers 201 1.1 christos is controlled by the macro 202 1.1 christos <a href="#HDRFTR_MARGIN">HEADER_MARGIN</a>, 203 1.1 christos which establishes the 204 1.1 christos <a href="definitions.html">baseline</a> 205 1.1 christos position of headers relative to the <em>top</em> edge of the page. 206 1.1 christos The header rule, whose position is relative to the header itself, 207 1.1 christos is controlled by a separate macro. 208 1.1 christos <strong>FOOTER_MARGIN</strong> establishes the baseline position of 209 1.1 christos footers relative to the <em>bottom</em> edge of the page. 210 1.1 christos <p> 211 1.1 christos <a href="#HDRFTR_GAP">HEADER_GAP</a> establishes 212 1.1 christos the distance between headers and the <em>start</em> of running text (effectively 213 1.1 christos making <strong>HEADER_MARGIN + HEADER_GAP</strong> the top margin of 214 1.1 christos running text unless you give <strong>mom</strong> a literal top margin 215 1.1 christos (with 216 1.1 christos <a href="typesetting.html#T_MARGIN">T_MARGIN</a>), 217 1.1 christos in which case she ignores <strong>HEADER_GAP</strong> and starts 218 1.1 christos running text at whatever top margin you gave. 219 1.1 christos <strong>FOOTER_GAP</strong> and 220 1.1 christos <a href="typesetting.html#B_MARGIN">B_MARGIN</a> 221 1.1 christos work similarly, except they determine where running text 222 1.1 christos <em>ends</em> on the page.

It's really quite 228 1.1 christos simple. By default, <strong>mom</strong> sets headers 4-1/2 229 1.1 christos <a href="definitions.html#TERMS_PICASPOINTS">picas</a> 230 1.1 christos down from the top of the page and starts running text 3 picas (the 231 1.1 christos <strong>HEADER_GAP</strong>) beneath that, which means the 232 1.1 christos effective top margin of running text is 7-1/2 picas (visually approx. 1 233 1.1 christos inch). If you give <strong>mom</strong> a literal top margin (with 234 1.1 christos <a href="typesetting.html#T_MARGIN">T_MARGIN</a>), 235 1.1 christos she ignores the <strong>HEADER_GAP</strong> and starts running 236 1.1 christos text at whatever top margin you gave. 237 1.1 christos <p> 238 1.1 christos Footers are treated the same way, the only difference being the 239 1.1 christos default distances. <strong>Mom</strong> sets footers 3 picas up from 240 1.1 christos the bottom of the page, and interrupts the processing of running text 3 241 1.1 christos picas (the <strong>FOOTER_GAP</strong>) above that (again, visually 242 1.1 christos approx. 1 inch). If you give <strong>mom</strong> a literal bottom 243 1.1 christos margin (with <a 244 1.1 christos href="typesetting.html#B_MARGIN">B_MARGIN</a>), she ignores the 245 1.1 christos <strong>FOOTER_GAP</strong> and interrupts the processing of running 246 1.1 christos text at whatever bottom margin you gave. 247 1.1 christos <p> 248 1.1 christos If <strong>mom</strong> is paginating your document (she 249 1.1 christos does, by default, at the bottom of each page), the vertical 250 1.1 christos spacing and placement of page numbers, whether at the top 251 1.1 christos or the bottom of the page, is managed exactly as if the 252 1.1 christos page numbers were headers (or footers), and are controlled 253 1.1 christos by the same macros.
