The tags are, of course, macros, but with sensible, readable names that make them easy to grasp and easy to remember. (And don’t forget: if you don’t like the “official” name of a tag — too long, cumbersome to type in, not “intuitive” enough — you can change it with the <a href="goodies.html#alias">ALIAS</a> macro.) </p> <p> In addition to the tags themselves, mom has an extensive array of macros that control how they look and behave. </p> <p> Setting up a mom doc is a simple, four-part procedure. You begin by entering metadata about the document itself (title, subtitle, author, etc.). Next, you tell mom what kind of document you’re creating (e.g., chapter, letter, abstract, etc...) and what kind of output you want (typeset, typewritten, draft-style, etc) — essentially, templates. Thirdly, you make as many or as few changes to the templates as you wish; in other words, create a style sheet. Lastly, you invoke the <kbd><a href="#start">START</a></kbd> macro. Voilà! You’re ready to write. </p> <!-- ==================================================================== --> <h2 id="defaults" class="docs">Document defaults</h2> <p> As is to be expected, mom has defaults for everything. If you want to know a particular default, read about it in the description of the pertinent tag. </p> <p> I fear the following may not be adequately covered in the documentation, so just in case: </p> <ul style="margin-top: -.5em; margin-bottom: .5em;"> <li>the paper size is 8.5x11 inches</li> <li>the left and right margins are 1-inch</li> <li>the top and bottom margins for document text are plus/minus visually 1-inch </li> <li>pages are numbered; the number appears centred, at the bottom, surrounded by hyphens ( e.g., -6- ) </li> <li>the first page of a document begins with a <a href="definitions.html#docheader">document header</a> </li> <li>subsequent pages have <a href="definitions.html#header">page headers</a> with a rule underneath </li> </ul> <!-- ==================================================================== --> <h2 id="vertical-whitespace-management" class="macro-group">Vertical whitespace management</h2> <ul style="margin-left: -.5em;"> <li><a href="#shim">Macro: SHIM</a></li> <li><a href="#no-shim">Macro: NO_SHIM</a></li> <li><a href="#flex">Macro: FLEX</a></li> <li><a href="#no-flex">Macro: NO_FLEX</a></li> </ul> <p> Mom takes evenly-aligned bottom margins in <a href="definitions.html#running">running text</a> very seriously. Only under a very few, exceptional circumstances will she allow a bottom margin to “hang” (ie to fall short). </p> <p> Mom offers two modes of operation for ensuring flush bottom margins: shimming and flex-spacing. Shimming means that mom nudges the next line after a significant break in running text back onto the <a href="definitions.html#baseline-grid">baseline grid</a> (e.g., after the insertion of a graphic). Flex-spacing means that any vertical whitespace remaining between the end of running text and the bottom margin is distributed equally at logical points on the page. </p> <p> Mom uses the <a href="definitions.html#leading">leading</a> of running text (the “document leading”) that’s in effect <i>at the start of running text on each page</i> to establish the grid and space document elements such as heads or blockquotes so that they adhere to it. (Prior to invoking <a href="#start">START</a>, the document leading is set with the <a href="typesetting.html#macros-typesetting">typesetting macro</a> <a href="typesetting.html#leading">LS</a>, afterwards with the document <a href="definitions.html#controlmacro">control macro</a> <a href="#doc-lead">DOC_LEAD</a>.) </p> <p> What this means is that documents whose paragraphs are not separated by whitepace and which do not contain graphics or <a href="definitions.html#pre-processor">pre-processor material</a> will fill the page completely to the bottom margin. However, if your paragraphs are spaced, or if there are any leading changes on a page, or if graphics or pre-processor material are inserted, it’s very likely the bottom margins will hang unless shimming or flex-spacing is enabled. </p> <h3 id="shim-vs-flex" class="docs">Shimming <span style="text-transform: none">vs.</span> flex-spacing</h3> <p> <b>Shimming</b> is mom's default mode of operation. She applies it automatically before headings, around quotes and blockquotes, and beneath <a href="definitions.html#float">floats</a> and <a href="definitions.html#preprocessor">pre-processor material</a>. In addition, the <a href="#shim">SHIM</a> macro can be inserted into a document to make sure that the text following falls on the baseline grid. </p> <p> This mode of operation works well in documents whose paragraphs are not spaced. Deviations from the baseline grid, usually caused by floats or pre-processor material, are corrected immediately. If the shimming results in slightly unbalanced whitespace around them, it can easily be remedied by passing the <kbd>ADJUST</kbd> argument to the appropriate macro. </p> <p> If you do not want mom shimming automatically, <a href="#no-shim">NO_SHIM</a> turns shimming off globally and suppresses the SHIM macro. If you want to disable shimming only for a particular float or pre-processor, the <kbd>NO_SHIM</kbd> argument may be given to the appropriate macro. </p> <p> <b>Flex-spacing</b> kicks in automatically whenever you turn shimming off. In other words, if you want a document flex-spaced, <kbd>.NO_SHIM</kbd> is how you achieve it. If, in addition to not shimming, you don’t want mom flex-spacing either, <a href="#no-flex">NO_FLEX</a> lets you disable it, too. </p> <p> Flex-spacing differs from shimming in that mom doesn’t correct deviations from the baseline grid. Rather, she distributes whitespace left at the bottom of the page equally in appropriate places. Like shimming, flex-spacing is automatically applied before heads, after floats and pre-processor material, and around quotes and blockquotes. Like shimming, flex-spacing can be disabled for individual floats or pre-processor material with the <kbd>NO_FLEX</kbd> flag. </p> <p> In addition, you can use the <a href="#flex">FLEX</a> macro to insert flex-spacing yourself into the document, which you will almost certainly want to do if your paragraphs are spaced. This is because paragraphs are not flex-spaced. Typographically, the ideal for spaced paragraphs is that the space between them remain constant. Paradoxically, the only way to achieve flush bottom margins, or to correct excessive flex-spacing before a heading, is by adding flex-space between paragraphs. This requires human judgment, and mom does not presume to decide for you. </p> <p> Shimming and flex-spacing are mutually exclusive. If the one is active, the other isn’t unless you have disabled both. This means that you cannot use the FLEX macro when shimming is enabled, or the SHIM macro when flex-spacing is enabled. Mom will issue a warning if you do. </p> <p> The choice of whether to use shimming or flex-spacing depends on whether or not your paragraphs are spaced. In a document with indented, non-spaced paragraphs, shimming and flex-spacing produce nearly the same result, with shimming winning by an aesthetic hair. In documents with spaced paragraphs, flex-spacing is the only way to achieve flush bottom margins. </p> <!-- -SHIM- --> <div class="macro-id-overline"> <h3 id="shim" class="macro-id">SHIM</h3> </div> <div class="box-macro-args"> Macro: <b>SHIM</b> </div> <p> When shimming is enabled, which it is by default, the SHIM macro allows you to nudge the line following it back onto the baseline grid. In documents with non-spaced paragraphs, this prevents the bottom margins from hanging. </p> <p style="margin-bottom: -1em"> Mom herself automatically applies shimming </p> <ul> <li><i>before</i> headings</li> <li><i>around</i> quotes and blockquotes</li> <li><i>after</i> PDF images, tables, pic diagrams, equations, and floats</li> </ul> <p> You may sometimes find the amount of space generated by <kbd>SHIM</kbd> looks too big, whether inserted manually into a document or as a result of automatic shimming. The situation occurs when the amount of shimming applied comes close to the leading currently in effect, making it seem as if there’s one linespace too much whitespace. </p> <p> The solution is simply to add <kbd>.SPACE -1v</kbd> or <kbd>.RLD 1v</kbd> to the document immediately after <kbd>.SHIM</kbd>. (Both <kbd>.SPACE -1v</kbd> and <kbd>.RLD 1v</kbd> back up by one linespace.) </p> <div class="macro-id-overline"> <h3 id="no-shim" class="macro-id">NO_SHIM</h3> </div> <div class="box-macro-args"> Macro: <b>NO_SHIM</b> <kbd class="macro-args"><none> | <anything> </div> <p> NO_SHIM, without an argument, disables automatic shimming, suppresses the SHIM macro, and enables flex-spacing. </p> <p> NO_SHIM with any argument (e.g., <b>OFF, QUIT, END, X</b>, etc) re-enables shimming if it has been disabled and disables flex-spacing. </p> <!-- -FLEX- --> <div class="macro-id-overline"> <h3 id="flex" class="macro-id">FLEX</h3> </div> <div class="box-macro-args"> Macro: <b>FLEX</b> <kbd class="macro-args">[ FORCE ]</kbd> </div> <p> When flex-spacing is enabled, the FLEX macro inserts flexible vertical whitespace into a document.

This is a result of mom flex-spacing <i>after</i> such material but not before. The solution to is insert <kbd>.FLEX</kbd> immediately beforehand. </p> <p> There are some instances where mom inhibits flex-spacing, notably after outputting deferred floats and pre-processor material. Introducing FLEX by itself in these instances—say, before a head or paragraph—will not have any effect; you must pass FLEX the <kbd>FORCE</kbd> argument. </p> <div class="box-tip"> <p class="tip"> <span class="important">Important note on flex-spacing policy:</span><br/> Mom disables flex-spacing on </p> <ul style="margin-top: -1em; margin-bottom: -.5em"> <li>the last page or column of a document, before the Table of Contents, Endnotes, Bibliography, and/or any “Lists of...” </li> <li>the page preceding a <a href="rectoverso.html#collate">COLLATE</a> </li> <li>the page preceding a <a href="typesetting.html#NEWPAGE">NEWPAGE</a> or <a href="headfootpage.html#blankpage">BLANKPAGE</a> </li> <li>the column preceding a <a href="#col-next">COL_NEXT</a> or <a href="#col-break">COL_BREAK</a> </li> </ul> <p> If this is not what you want, insert <a href="#no-flex"><kbd>.NO_FLEX OFF</kbd></a> before the first flex-space point on the affected page or in the affected column. </p> <p> Flex-spacing is also disabled for any page or column where insufficient room at or near the bottom causes a <a href="docelement.html#heading">HEADING</a> or <a href="images.html#tbl">table</a> to be moved to the top of the next page. These situations cannot be harmonized with flex-spacing except by adjusting your layout to prevent them. You may try re-enabling flex-spacing for the page (<kbd>.NO_FLEX OFF</kbd>) and manually inserting flex-spaces at appropriate points, but the original whitespace is usually large enough that re-distributing it merely changes one layout gaffe into another. </p> <p> Very occasionally you may notice that a document element (spaced paragraph, floated material, pre-processor material, or a PDF image) near the bottom of page has also caused mom to disable flex-spacing for that page. This occurs when the document element following it is a <a href="docelement.html#pp-space">spaced paragraph</a>. </p> <p> It is typographically acceptable for there to be space between insertions in running text (e.g., an image) and the bottom margin when the next page begins with a paragraph. If you’d like to nudge the insertion a little closer to the bottom margin—not all the way; that isn’t possible without pushing it to the next page and disrupting subsequent flex-spacing—insert a small amount of space beforehand with <a href="typesetting.html#sp">SP</a>. Do not, in these cases, use the <kbd>ADJUST</kbd> argument (for example to <a href="images.html#pdf-image">PDF_IMAGE</a>.) </p> <p class="tip-bottom"> In the case of a spaced paragraph itself near the bottom of the page causing a break, re-enabling flex-spacing (<kbd>.NO_FLEX OFF</kbd>) at an appropriate place in your input file will resolve the issue, provided there is at least one flex-point on the page.

Before we proceed, though, be reassured that something as simple as <br/> <span class="pre-in-pp"> .TITLE "By the Shores of Lake Attica" .AUTHOR "Rosemary Winspeare" .PRINTSTYLE TYPESET .START </span> produces a beautifully typeset 8.5x11 document, with a <a href="definitions.html#docheader">docheader</a> at the top of page 1, <a href="definitions.html#header">page headers</a> with the title and author on subsequent pages, and page numbers at the bottom of each page. In the course of the document, headings, citations, quotes, epigraphs, and so on, all come out looking neat, trim, and professional. </p> <p> For the purposes of this tutorial, we’re going to set up a short story—<i>My Pulitzer Winner</i>—by Joe Blow. Thankfully, we don’t have to look at story itself, just the setup. Joe wants the document </p> <ul style="margin-top: -.5em; margin-bottom: -.5em;"> <li>to be draft 7, revision 39;</li> <li>to use the DEFAULT template;</li> <li>to print as draft-style output (instead of final-copy output);</li> <li>to be typeset, in Helvetica, 12 on 14, <a href="definitions.html#rag">rag-right</a>; </li> <li>to have <a href="definitions.html#footer">footers</a> instead of <a href="definitions.html#header">headers</a>; </li> <li>to use a single asterisk for <a href="definitions.html#linebreak">author linebreaks</a>. </li> </ul> <p> Joe Blow has no taste in typography. His draft won’t look pretty, but this is, after all, a tutorial; we’re after examples, not beauty. </p> <h4 class="docs" style="margin-top: -.5em;">Step 1</h4> <p style="margin-bottom: -.5em;"> The first step in setting up any document is giving mom some reference information (metadata). The reference macros are: </p> <div style="width: 50%; float: left;"> <ul> <li>TITLE</li> <li>SUBTITLE</li> <li>AUTHOR</li> <li>CHAPTER – chapter number</li> <li>CHAPTER_TITLE – chapter name</li> <li>DRAFT – the draft number</li> <li>REVISION – the revision number</li> </ul> </div> <div> <ul> <li>COPYRIGHT – only used on cover pages</li> <li>MISC – only used on cover pages</li> <li>DOCTITLE</li> <li>COVERTITLE</li> <li>DOC_COVERTITLE</li> <li>PDF_TITLE</li> </ul> </div> <p style="margin-top: -.5em; clear: both;"> You can use as many or as few as you wish, although at a minimum, you’ll probably fill in TITLE (unless the document’s a letter) and AUTHOR. Order doesn’t matter. You can separate the <a href="definitions.html#arguments">arguments</a> from the macros by any number of spaces. The following are what you’d need to start Joe Blow’s story. <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 </span> </p> <h4 class="docs" style="margin-top: -1.5em;">Step 2</h4> <p> Once you’ve given mom the reference information she needs, you tell her how you want your document formatted. What kind of document is it? Should it be typeset or typewritten? Is this a final copy (for the world to see) or just a draft? Mom calls the macros that answer these questions “the docstyle macros”, and they're essentially templates. </p> <ul style="margin-top: -.5em; margin-bottom: -.5em;"> <li>PRINTSTYLE—typeset or typewritten</li> <li>DOCTYPE—the type of document (default, chapter, user-defined, letter)</li> <li>COPYSTYLE —draft or final copy</li> </ul> <p> Mom has defaults for DOCTYPE and COPYSTYLE; if they’re what you want, you don’t need to include them. However, PRINTSTYLE has no default and must be present in every formatted document. If you omit it, mom won’t process the document AND she’ll complain (both to stderr and as a single printed sheet with a warning). Moms—they can be so annoying sometimes. <sigh> </p> <p> Adding to what we already have, the next bit of setup for Joe Blow’s story looks like this: <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 \# .DOCTYPE DEFAULT \"Superfluous; mom uses DOCTYPE DEFAULT by default .PRINTSTYLE TYPESET .COPYSTYLE DRAFT </span> Notice the use of the <a href="definitions.html#commentlines">comment line</a> ( <kbd>\#</kbd> ), a handy way to keep groups of macros visually separated for easy reading in a text editor. </p> <h4 class="docs" style="margin-top: -.5em; margin-bottom: -.5em;">Step 3</h4> <p> This step—completely optional—is where you, the user, take charge. Mom has reasonable defaults for every document element and tag, but who’s ever satisfied with defaults? Use any of the <a href="typesetting.html#macros-typesetting">typesetting macros</a> here to change mom’s document defaults (paper size, margins, family, point size, line space, rag, etc), or any of the document processing <a href="definitions.html#controlmacro">control macros</a>. This is the style-sheet section of a document, and must come after the <a href="#printstyle">PRINTSTYLE</a> directive. Failure to observe this condition will result in PRINTSTYLE overriding your changes. </p> <p> Joe Blow wants his story printed in Helvetica, 12 on 14, rag right, with <a href="definitions.html#footer">page footers</a> instead of <a href="definitions.html#header">page headers</a> and a single asterisk for the <a href="definitions.html#linebreak">linebreak</a> character. None of these requirements conforms to mom’s defaults for the chosen PRINTSTYLE (TYPESET), so we change them here. The setup for Joe Blow’s story now looks like this: <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 \# .DOCTYPE DEFAULT .PRINTSTYLE TYPESET .COPYSTYLE DRAFT \# .FAMILY H .PT_SIZE 12 .LS 14 .QUAD LEFT \"ie rag right .FOOTERS .LINEBREAK_CHAR * </span> </p> <h4 class="docs" style="margin-top: -1.5em; margin-bottom: -.5em;">Step 4</h4> <p> The final step in setting up a document is telling mom to start document processing. It’s a no-brainer, just the single macro START. Other than PRINTSTYLE, it’s the only macro required for document processing. </p> <p> Here’s the complete setup for <i>My Pulitzer Winner</i>: <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 \# .DOCTYPE DEFAULT .PRINTSTYLE TYPESET .COPYSTYLE DRAFT \# .FAMILY H .PT_SIZE 12 .LS 14 .QUAD LEFT \"ie rag right .FOOTERS .LINEBREAK_CHAR * \# .START </span> As pointed out earlier, Joe Blow is no typographer. Given that all he needs is a printed draft of his work, a simpler setup would have been: <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 \# .PRINTSTYLE TYPEWRITE .COPYSTYLE DRAFT \# .START </span> <kbd>.PRINTSTYLE TYPEWRITE</kbd>, above, means that Joe’s work will come out “typewritten, double-spaced”, making the blue-pencilling he (or someone else) is sure to do much easier (which is why many publishers and agents still insist on typewritten, double-spaced copy). </p> <p> When J. Blow stops re-writing and decides to print off a final, typeset copy of his work for the world to see, he need only make two changes to the (simplified) setup: <br/> <span class="pre-in-pp"> .TITLE "My Pulitzer Winner" .AUTHOR "Joe Blow" .DRAFT 7 .REVISION 39 \# .PRINTSTYLE TYPESET \"first change .COPYSTYLE FINAL \"second change \# .START </span> In the above, <kbd>.DRAFT 7, .REVISION 39,</kbd> and <kbd>.COPYSTYLE FINAL</kbd> are actually superfluous. The draft and revision numbers aren’t used when COPYSTYLE is FINAL, and <b>COPYSTYLE FINAL</b> is mom’s default unless you tell her otherwise. </p> <p> But... to judge from the number of drafts already, J. Blow may very well decide his “final” version still isn’t up to snuff. Hence, he might as well leave in the superfluous macros. That way, when draft 7, rev. 62 becomes draft 8, rev. 1, he’ll be ready to tackle his Pulitzer winner again. </p> </div> <div class="rule-short"><hr/></div> <!-- ======================================================================== --> <h2 id="reference-macros" class="macro-group">The reference macros (metadata)</h2> <p> The reference macros give mom the metadata she needs to generate <a href="definitions.html#docheader">docheaders</a>, <a href="definitions.html#header">page headers</a>, and <a href="cover.html#cover-top">covers</a>.

The default is 16:9. <span class="pre-in-pp"> 4:3 16:9 media size: 11" x 8.25" media size: 11" x 8.1875" left/right margins: 36 points left/right margins: 36 points top margin: 90 points top margin: 80 points bottom margin: 84 points bottom margin: 72 points base text size: 16 points base text size: 14 points autoleading: 6 points, adjusted autoleading: 4 points, adjusted (header/footer size: -3 points) (header/footer size: -2 points) </span> Note that both media sizes fit on either A4 or US LETTER papersizes. </p> <h5 class="docs" style="margin-top: .5em">Headers, footers, and pagination</h5> <p> If you want a header, footer, or both for your slides, pass SLIDES the <kbd>HEADER</kbd> and/or <kbd>FOOTER</kbd> argument(s). Both take three additional <a href="definitions.html#stringargument">string arguments</a>, which must be enclosed in double-quotes, defining the left, centre, and right parts of the header/footer. Any parts you want left blank should be entered as two double-quotes. For example, <span class="pre-in-pp"> HEADER "" "My slide presentation" "" </span> will result in a header with only the centre part. </p> <p> Normal pagination is disabled for slides. If you want your slides numbered, the slide number must be given to one of the header/footer parts with the <a href="definitions.html#inlines">inline escape</a> <br/> <kbd>\*[SLIDE#]</kbd>. For example: <span class="pre-in-pp"> HEADER "" "My slide presentation" "" \ FOOTER "" "" "\*[SLIDE#]" </span> will give you a centred header with numbering at the bottom right of the slide. </p> <p> The overall family, size, and colour of headers may be set with HEADER_FAMILY, HEADER_SIZE, and HEADER_COLOR. If you request FOOTERS, you may use the FOOTER_ equivalent of these macros. If you request both headers and footers, use one or the other but not both. For example, in a header/footer situation, HEADER_FAMILY would determine the family for both headers and footers, but if you attempted to do this <span class="pre-in-pp"> .HEADER_FAMILY T .FOOTER_FAMILY H </span> FOOTER_FAMILY would take precedence, and your header family would be “<kbd>H</kbd>”. </p> <p> All other formatting of individual header/footer parts must be entered as inline escapes inside the double-quotes. If you want, say, your headers to be red but your footer page numbering to be black and two points larger, this is how you’d do it: <span class="pre-in-pp"> .HEADER_COLOR red .DOCTYPE SLIDES \ HEADER "" "My slide presentation" "" \ FOOTER "" "" "\*[black]\*S[+2]\*[SLIDE#]\*S[-2]" </span> </p> <div class="box-tip"> <p class="tip"> <span class="note">Note:</span> Do not use mom’s <a href="inlines.html#inline-size-mom"><kbd>\*[SIZE ±n]</kbd></a> inline escape to change point size in the strings passed to HEADER or FOOTER. Prefer either mom’s <kbd>\*S[±n]</kbd> or groff's <kbd>\s[±n]</kbd>. </span> </p> </div> <h5 class="docs" style="margin-top: .5em">Transition</h5> <p> “Transition” refers to how new slides appear during a presentation. The official PDF specification lists a number of modes, each with a choice of configurable parameters. Modes include Box, Blinds, Wipe, Fade, and several others. Parameters include things like duration, dimension, and direction. There are a total of twelve modes; for each one there are from one to six configurable parameters. Consult <kbd>man gropdf(1)</kbd> for a complete listing of modes and parameters. </p> <p> If you pass SLIDES the <kbd>TRANSTION</kbd> argument, you must at a minimum follow it with a mode. Afterwards, you may give as many or as few parameters as you wish. Parameters are, in order, <span class="pre-in-pp"> 1. duration 2. dimension 3. motion 4. direction 5. scale 6. bool </span> You don't have to fill them all out. If you only need the first three, that's all you need to input. If you need the first and third, enter the second as a period (dot), which is used any time you want to leave a parameter at its current default or when it isn’t applicable. For example, if you want a Box transition that lasts 1 second, filling the screen from the centre outwards, you'd enter <span class="pre-in-pp"> TRANSITION "Box 1 . O" </span> because Box does not take a “dimension” parameter but it does take a motion parameter. </p> <p> Notice that the entire string (mode+parameters) must be enclosed in double-quotes. </p> <div class="box-tip"> <p class="tip"> <span class="note">Note:</span> Not all PDF viewers support all modes. Any that are not supported are replaced by the “R” mode, which simply replaces one slide with the next unless the PDF viewer has a different default transition mode. </span> </p> </div> <h5 class="docs" style="margin-top: .5em">Pause</h5> <p> A “pause” occurs when material on a slide is halted (see <a href="#pause">PAUSE</a>), awaiting a mouse click, PgDown, Next, or the spacebar to reveal subsequent material. All the same modes and parameters as <kbd>TRANSITION</kbd> may be used. The manner of entering them is is identical, including that the entire mode+parameter string must be enclosed in double-quotes. </p> <div class="macro-id-overline"> <h3 id="slide-macros" class="macro-id">SLIDE MACROS</h3> </div> <div id="newslide" class="box-macro-args"> Macro: <b>NEWSLIDE</b> <kbd class="macro-args">["<transition mode and parameters>"]</kbd> </div> <p> Unless you want material from one slide to flow onto the next, you need to tell mom when to start a new slide with the macro NEWSLIDE. Without any arguments, the new slide will appear with the default TRANSTION you gave to DOCTYPE SLIDES. </p> <p> If you would like a different transition, you may pass NEWSLIDE a new mode and associated parameters, following the same rules as the TRANSITION argument to DOCTYPE. Note that the new effect becomes the default. If you wish to return to the original transition, you must give it explicitly to the appropriate NEWSLIDE. </p> <div id="pause" class="box-macro-args"> Macro: <b>PAUSE</b> <kbd class="macro-args">["<pause mode and parameters>"]</kbd> </div> <p> Pauses in slides are accomplished by entering the macro PAUSE at desired locations in your input file.

For example, <br/> <span class="pre-in-pp"> .PAPER A4 .LS 14 .QUAD LEFT .PRINTSTYLE TYPESET </span> will not change mom’s default document leading to 14 points, nor the default justification style (fully justified) to left justified, whereas <br/> <span class="pre-in-pp"> .PAPER A4 .PRINTSTYLE TYPESET .LS 14 .QUAD LEFT </span> will. </p> </div> <p> <kbd>TYPESET</kbd>, as the argument implies, typesets documents (by default in Times Roman; see <a href="#typeset-defaults">TYPESET defaults</a>).

For example, <br/> <span class="pre-in-pp"> .ATTRIBUTE_STRING "par" </span> changes “by” to “par”. ATTRIBUTE_STRING can also be used, for example, to make the attribution read “Edited by”. </p> <p> If you don’t want an attribution string at all, simply pass ATTRIBUTE_STRING an empty argument, like this: <br/> <span class="pre-in-pp"> .ATTRIBUTE_STRING "" </span> Mom will deposit a blank line where the attribution string normally appears. </p> <p> If the optional argument, <kbd>COVER</kbd> or <kbd>DOC_COVER</kbd>, is given to ATTRIBUTE_STRING, the string argument represents the attribution string that will appear on cover or document cover pages (see the <a href="cover.html#cover-intro">Introduction to cover pages</a> for a description of the difference between “document covers” and “covers”). Thus, it is possible to have different attribution strings on the document cover page, the cover (“title”) page, and in the first-page docheader. An extreme example would be: <br/> <span class="pre-in-pp"> .ATTRIBUTE_STRING "" .ATTRIBUTE_STRING DOC_COVER "Edited by" .ATTRIBUTE_STRING COVER "by" </span> The first invocation of <kbd>.ATTRIBUTE_STRING</kbd> establishes a blank attribution string that will be incorporated in the first-page docheader. The second will print “Edited by” on the document cover; the third will print “by” on the cover (“title”) page. </p> <p> If you don’t require differing attribute strings for doc cover pages, cover pages, or the first-page docheader, <kbd>.ATTRIBUTE_STRING</kbd>, without either of the optional first arguments, is sufficient. </p> <div class="rule-short"><hr/></div> <!-- -COLUMNS- --> <h2 id="columns-intro" class="docs">Setting documents in columns</h2> <p> Setting documents in columns is easy with mom.

For example, if you turn kerning off, pairwise kerning is disabled not only in paragraphs, but also in headers, footers, quotes, and so on. </p> <p> Typesetting macros that alter margins and line lengths affect <a href="definitions.html#running">running text</a> globally (or at least try to), but leave headers/footers and footnotes alone. (To indent footnotes, see the full explanation of the <a href="docelement.html#footnote">FOOTNOTE</a> macro.) </p> <p> Mom’s tabs (both <a href="typesetting.html#typesetting-tabs">typesetting tabs</a> and <a href="typesetting.html#string-tabs">string tabs</a>) behave as expected in running text during document processing. Tab structures that do not exceed the line length of running text are preserved sensibly from page to page, and, if <a href="docprocessing.html#columns">COLUMNS</a> are enabled, from column to column. </p> <p> Some typesetting macros, however, when used during document processing, behave in special ways. These are the macros that deal with the basic parameters of type style: horizontal and vertical margins, line length, <a href="definitions.html#family">family</a>, <a href="definitions.html#font">font</a>, <a href="definitions.html#ps">point size</a>, <a href="definitions.html#leading">leading</a>, and <a href="definitions.html#quad">quad</a>. </p> <p> Mom assumes that any changes to these parameters stem from a temporary need to set type in a style different from that provided by mom’s <a href="docelement.html#index-docelement">document element tags</a>. In other words, you need to do a bit of creative typesetting in the middle of a document. </p> <p> The following lists those typesetting macros whose behaviour during document processing requires some explanation. (Please refer to <a href="#tb-margins">Top and bottom margins in document processing</a> for information on how mom interprets <a href="typesetting.html#t-margin">T_MARGIN</a> and <a href="typesetting.html#b-margin">B_MARGIN</a> in document processing. Additionally, see <a href="#add-space">ADD_SPACE</a> if you encounter the problem of trying to get mom to put space at the tops of pages after the first.) </p> <div id="behaviour-specific" class="box-code" style="margin-left: 24px;"> <span class="pre" style="color: #302419;"> MACRO EFFECT DURING DOCUMENT PROCESSING ----- --------------------------------- L_MARGIN •The left margin of all running text assumes the new value. •The line length remains unaltered. •The header and footer left margin remain at the current document default. (You won’t use this often by itself. Most likely, you’ll use it in combination with R_MARGIN or LL.) R_MARGIN •The right margin of all running text assumes the new value. In other words, the line length is altered. •The header and footer right margin remain at the current document default. LL •The line length of all running text is set to the new value. •The header and footer line length remain at the current document default. FAMILY •Changes family for the duration of the current tag only. As soon as another document element tag is invoked, the family reverts to the current default for the new tag. FT •Changes font for the duration of the current tag only. As soon as another document element tag is entered, the font reverts to the current default for the new tag. N.B. — \*[SLANT] and \*[BOLDER] affect paragraph text, and remain in effect for all paragraphs until turned off. If you want to use them in a macro that takes a string argument, include the escape in the string. \*[COND] and \*[EXT] behave similarly. PT_SIZE •Changes point size for the duration of the current tag only. As soon as another document element tag is entered, the point size reverts to the current document default for the new tag. LS •Changes line space for the duration of the current tag only. As soon as another document element tag is entered, the line space reverts to the current document default for the new tag. Using LS to temporarily change leading within a document will almost certainly result in a bottom margin that doesn’t align with the bottom margin of subsequent pages. You’ll need to use the SHIM or FLEX macro to get mom back on track when you’re ready to return to the document’s default leading. <a id="autolead" style="margin-top: -1em">AUTOLEAD</a> •Invoked before START, sets the overall document leading as a function of the overall document point size (ie the point size used in paragraphs); subsequently disabled after START, except for calls to DOC_PT_SIZE •DOC_LEAD before DOC_PT_SIZE cancels the AUTOLEAD set before START •Invoked after START, remains in effect for all subsequent point size changes made with PT_SIZE, but does not affect the leading of the document element tags (e.g., HEADING, PP, QUOTE...), or calls to DOC_PT_SIZE QUAD •Changes quad for the duration of the current tag only. As soon as another document element tag is entered, the quad reverts to the current document default for the new tag. N.B. — Line-for-line quadding macros (LEFT, CENTER, RIGHT) are also temporary, overridden by the QUAD value of any subsequent document element tag. </span> </div> <h3 id="tb-margins" class="docs" style="margin-top: 1.5em;">Top and bottom margins in document processing</h3> <p> Normally, mom establishes the top and bottom margins of <a href="definitions.html#running">running text</a> in documents from the values of <b>HEADER_MARGIN + HEADER_GAP</b> and <b>FOOTER_MARGIN + FOOTER_GAP</b> respectively. However, if you invoke <a href="typesetting.html#t-margin">T_MARGIN</a> or <a href="typesetting.html#b-margin">B_MARGIN</a> either before or after <a href="docelement.html#start">START</a>, they set the top and bottom margins of running text irrespective of HEADER_GAP and FOOTER_GAP. </p> <p> Put another way, in document processing, T_MARGIN and B_MARGIN set the top and bottom margins of running text, but have no effect on the placement of <a href="definitions.html#header">headers</a>, <a href="definitions.html#footer">footers</a>, or page numbers. </p> <!-- ==================================================================== --> <h3 id="space" class="docs">Inserting space at the top of a new page</h3> <p> Occasionally, you may want to insert space before the start of <a href="definitions.html#running">running text</a> on pages after the first. </p> <p> You might have tried using <a href="typesetting.html#ald">ALD</a> or <a href="typesetting.html#space">SPACE</a> and found it did nothing.

Depending on the <a href="definitions.html#filled">fill mode</a> in effect, you may also have to append the “join line” <a href="definitions.html#inlines">escape</a>, <kbd>\c</kbd>, to the final line.</p> <p> Thus, for normal text at the end of a paragraph, which is in fill mode, <br/> <span class="pre-in-pp"> and they all lived happily ever after. .EL </span> or for ending a <a href="docelement.html#list-intro">LIST</a> (also in fill mode) <span class="pre-in-pp"> .ITEM peaches, pears, plums .EL .LIST OFF </span> whereas, at the end of a <a href="docelement.html#quote-intro">QUOTE</a> (which is in nofill mode), <span class="pre-in-pp"> Shall be lifted\[em]nevermore!\c .EL .QUOTE OFF </span> Notice that the <kbd>.EL</kbd> comes after the last line of input text, not any macros following. </p> <div class="box-tip"> <p class="tip"> <span class="note">Note:</span> <a href="inlines.html#b"><kbd>\*[B]</kbd></a> cannot be used as a replacement for <kbd>.EL</kbd> when terminating a document. </p> </div> <!-- Navigation links --> <table style="width: 100%; margin-top: 12px;"> <tr> <td style="width: 33%;"><a href="toc.html">Back to Table of Contents</a></td> <td style="width: 24%; text-align: center;"><a href="#top">Top</a></td> <td style="width: 43%; text-align: right;"><a href="docelement.html#top">Next: The document element tags</a></td> </tr> </table> </div> <div class="bottom-spacer"><br/></div> </body> </html>Private
