NAME

yodlmacros - Macros for the Yodl converters

SYNOPSIS

This manual page lists the standard macros of the Yodl package.

DESCRIPTION

The following list shows the macros defined by the Yodl converters define and which can be used in Yodl documents. Refer to the Yodl user guide, distributed with the Yodl package, for a full description.

NOTE: Starting with Yodl version 3.00.0 Yodl’s default file inclusion behavior has changed. The current working directory no longer remains fixed at the directory in which Yodl is called, but is volatile, changing to the directory in which a yodl-file is located. This has the advantage that Yodl’s file inclusion behavior now matches the way C’s #include directive operates; it has the disadvantage that it may break some current documents. Conversion, however is simple but can be avoided altogether if Yodl’s -L (--legacy-include) option is used. This affects the (l)includefile, includeverbatim, notransinclude and verbinclude macros (see below).

The following list shows all macros of the package in alphabetical order.

abstract(text)

Defines an abstract for an article or report document. Abstracts are not implemented for books or manpages. Must appear before starting the document with the article or report macro.

addntosymbol(symbol)(n)(text)

Adds text n times to symbol. The value n may also be the name of a defined counter (which itself will not be modified).

affiliation(site)

Defines an affiliation, to appear in the document titlepage below the author field. Must appear before starting the document with article, report or book. The affiliation is only printed when the author field is not empty. When converting to html the way the affiliation is displayed can be tuned using CSS id selector specifications. The affiliation has id="affiliation".

AfourEnlarged()

Enlarges the usable height of A4 paper by 2 cm.: the top margin is reduced by 2 cm. This macro should be called in the preamble. The macro is available only for LaTeX conversions.

appendix()

Starts appendices

article(title)(author)(date)

Starts an article. The top-level sectioning command is (n)sect. In HTML conversions only one output file is written, while the way the headings are displayed can be tuned using CSS id selector specifications: the title has id="title", the author id="author", and the date id="date".)

attrib(text)

In html, pushes text as an attribute for the next html tag supporting attrib. E.g, to set a blue color and 30 pixel left-hand side margin for a section use



    attrib(style="color:blue;margin-left:30px;")\ 


    sect(Section name)

This results in the html markup



    <h1 style="color:blue;margin-left:30px;">Section name</h1>

This macro is only effective with html conversions. It is applied in a stack-wise fasion: when multiple attrib calls are used, then the topmost attrib-string is added to the first macro calling the attribinsert macro, with subsequent macros using subsequent elements on the attrib-stack.

Commonly used attributes are id="idname", expecting a #idname CSS label in either internal or external CSS specifications, or style="spec" (as shown in the example).

Example: when using



    attrib(width = "100" height = "100")


    attrib(id = "#fig")


    figure(imgfile)(Caption)(IMG)

then the #id attribute is applied to <figure>, and the width and height attributes are applied to <img>, which html markup is inserted by the figure macro.

The attrib macro is supported by the following predefined macros (between parentheses the number of attribute strings that are inserted by these macros; if only 1 attribute string is inserted no number is shown):

bf cell cells center chapter code dashes dit em figure(3) file htmltag itdesc lchapter link lref lsect lsubsect lsubsubsect nchapter npart nsect nsubsect nsubsubsect paragraph part quote row sc sect strong subs subsect subsubsect subsubsubsect sups tableatt tt ttbegin url verb verborg verbinclude.

attribclear()

Removes any existing contents from the attrib-stack. This macro is only active when converting to html

attribinsert()

In html, if the attrib-stack is not empty, inserts the value on top of the attrib-stack and then pops the topmost value. If the attrib-stack is empty, nothing happens.

bf(text)

Sets text in boldface.

bind(text)

Generate a binding character after text.

book(title)(author)(date)

Starts a book document. The top-level sectioning command is (n)chapter, (n)part being optional. In HTML output files are created for each chapter, while the way the headings are displayed can be tuned using CSS id selector specifications: the title has id="title", the author id="author", and the date id="date".)

cell(contents)

Sets a table cell, i.e., one element in a row. With the man/ms converters multiple blanks between cell() macro calls are merged into a single blank character.

cells(nColumns)(contents)

Set a table cell over nColumns columns. With LaTeX and xml the information in the combined cells is centered.

With man/ms conversions the cells() macro simply calls the cell() macro, but here the setmanalign() macro can be used to determine the alignment of multiple cells.

With html the macro attrib can be used, but when it contains a style specification the macro’s default style="text-align: center" is ignored (but it can optionally be specified using the attrib macro).

cellsline(from)(count)

Sets a horizontal line starting at column number from over count columns in a row. If from is less then the number of columns already added to a row then it is ignored. This macro must be embedded in a row macro defining a table row. To put a line across the table’s full width use rowline. To set horizontal lines across columns 1 until 2 and columns 4 until 5 table of a table use:



    row(cellsline(1)(2)cellsline(4)(2))

Combining cellsline and cell or cells calls in one row produces undefined results.

center(text)

Centers text. Use nl() in the text to break lines. In html the attrib macro is not supported, but a division (div) with style definition text-align: center is used. To center a table in html use the tableatt macro. If a table or tableatt macro is used inside a center macro then the contents of columns are column-wise centered.

chapter(title)

Starts a new chapter in books or reports.

cindex()

Generate an index entry for LaTex() or texinfo c-indices. Its argument is the index entry. See also the [fptv]index macro.

cite(1)

Sets a citation or quotation

clearpage()

Starts a new page, when the output format permits. Under HTML a horizontal line is drawn.

code(text)

Sets text in code font, and prevents it from being expanded. For unbalanced parameter lists, use CHAR(40) to get ( and CHAR(41) to get ).

columnline(from)(to)

Sets a horizontal line over some columns in a row. Note that columnline defines a row by itself, consisting of just a horizontal line spanning some of its columns, rather than the table’s full width, like rowline. The two arguments represent column numbers. It is the responsibility of the author to make sure that the from and to values are sensible. I.e.,



    1 <= from <= to <= ncolumns

Note: this macro cannot be used if multiple lines must be set in one row. In those cases the macro colsline should be used.

dashes()

Inserts two Sets text in teletype font, and prevents it from being expanded. For unbalanced parameter lists, use CHAR(40) to get ( and CHAR(41) to get ).

The tt macro interprets character tables as well as SUBST definitions. This is usually what is intended. In situations where tt performs unwelcome transformations, use the pair of ttbegin and ttend macros.

In html the attrib macro applies to the <code> tag.

def(macroname)(nrofargs)(redefinition)

Defines macroname as a macro, having nrofargs arguments, and expanding to redefinition. This macro is a shorthand for DEFINEMACRO. An error occurs when the macro is already defined. Use redef() to unconditionally define or redefine a macro.

description(list)

Sets list as a description list. Use dit(item) to indicate items in the list.

dit(itemname)

Starts an item named itemname in a description list. The list should be used in description macros. With html conversions the contents of a description item is separated from the item itself. The dit macro only defines the item, and not the description itself. This macro sets the item in bold-face (`strong’ font). The macro itdesc, available since Yodl 3.05, can be used to defines an item and its description, using its suggested format (i.e., indenting the description relative to the item).

eit()

Indicates an item in an enumerated list. The eit macro should be used as an argument in enumeration macros.

ellipsis()

Sets ellipsis (...).

em(text)

Sets text as emphasized, usually italics.

email(address)

In HTML, this macro sets the address in a <a href="mailto=.."> locator. In other output formats, the address is sent to the output. The email macro is a special case of url.

enumeration(list)

enumeration() starts an enumerated list. Use eit() in the list to indicate items in the list.

euro()

Sets the euro currency symbol in latex, html, (and possibly sgml and xml). In all other conversions EUR which is the official textual abbreviation (cf. http://ec.europa.eu/euro/entry.html) is written. Note that LaTeX may require latexpackage()(eurosym).

fig(label)

This macro is a shorthand for figure ref(label) and just makes the typing shorter, as in see fig(schematic) for .. See getfigurestring() and setfigurestring() for the figure text.

figure(file)(caption)(label)

Sets the picture in file as a figure in the current document, using the descriptive text caption. The label is defined as a placeholder for the figure number and can be used in a corresponding ref statement. Note that the file must be the filename without extension: By default, Yodl will supply .gif when in HTML mode, or .ps when in LaTeX mode. Figures in other modes may not (yet) haven been implemented.

When converting to html, this macro uses three attribute-strings (if available). The string pushed first using an attrib-call defines the attributes for its <figcaption> html-markup; the string pushed next defines the attributes for its <img> html-markup; the string pushed last defines the attributes for its <figure> html-markup. The figure macro’s html output is organized like this:



    <figure -attrib-string pushed last (if any)>


        <img ... -attrib-string pushed last but one>


        <figcaption -attrib-string pushed 2nd to last>


            ...


        </figcaption>


    </figure>

Starting with Yodl 3.07.00 no alt="Figure # is shown here..." attribute is defined anymore for the img markup: an alt-attribute can easily be defined at the last attrib-call, using getfigurestring() to obtain Figure or its language-specific translation, and COUNTERVALUE(XXfigurecounter) to obtain the order-number of the figure shown in the next figure-macro call.

file(text)

Sets text as filename, usually boldface. In html attrib macro applies to the <strong> tag.

findex()

Generate an index entry for LaTex() or texinfo f-indices. Its argument is the index entry. See also the [cptv]index macro.

footnote(text)

Sets text as a footnote, or between parentheses when the output format does not allow footnotes.

gagmacrowarning(name name ...)

Prevents the yodl program from printing cannot expand possible user macro. E.g., if you have in your document the file(s) are .. then you might want to put before that: gagmacrowarning(file). Calls NOUSERMACRO.

getaffilstring()

Expands to the string that defines the name of Affiliation Information, by default AFFILIATION INFORMATION. Can be redefined for national language support by setaffilstring(). Currently, it is relevant only for txt.

getauthorstring()

Expands to the string that defines the name of Author Information, by default AUTHOR INFORMATION. Can be redefined for national language support by setauthorstring(). Currently, it is relevant only for txt.

getchapterstring()

Expands to the string that defines a `chapter’ entry, by default Chapter. Can be redefined for national language support by setchapterstring().

getdatestring()

Expands to the string that defines the name of Date Information, by default DATE INFORMATION. Can be redefined for national language support by setdatestring(). Currently, it is relevant only for txt.

getfigurestring()

Returns the string that defines a `figure’ text, in captions or in the fig() macro. The string can be redefined using the setfiguretext() macro.

getpartstring()

Expands to the string that defines a `part’ entry, by default Part. Can be redefined for national language support by setpartstring().

gettitlestring()

Expands to the string that defines the name of Title Information, by default TITLE INFORMATION. Can be redefined for national language support by settitlestring(). Currently, it is relevant only for txt.

gettocstring()

Expands to the string that defines the name of the table of contents, by default Table of Contents. Can be redefined for national language support by settocstring().

htmlcommand(cmd)

Writes cmd to the output when converting to html. The cmd is not further expanded by Yodl.

htmlheadfile(file)

Adds the contents of file to the head section of an HTML document. The contents of file are not interpreted and should contain plain html text. This option can be useful when large bodies of text, like the contents of <script> sections, must be included into the head section of html documents. This macro is only active in the preamble, should only specified once, and is only interpreted for html conversions.

htmlheadopt(option)

Adds the literal text option to the current information in the head section of an HTML document. Option may (or: should) contain plain html text. A commonly occurring head option is link, defining, e.g., a style sheet. Since that option is frequently used, it has received a dedicated macro: htmlstylesheet. When large bodies of html-text must be added to html documents the macro htmlheadfile should be used. This macro is only active in the preamble and is only interpreted for html conversions.

htmlnewfile()

In HTML output, starts a new file. All other formats are not affected. Note that you must take your own provisions to access the new file; say via links. Also, it’s safe to start a new file just befoore opening a new section, since sections are accessible from the clickable table of contents. The HTML converter normally only starts new files prior to a chapter definition.

htmlstyle(tag)(definition)

Adds <style type="text/css"> ... </style> element to the head section of an HTML document.
Use htmlstyle to specify one or more CSS definitions which are eventually inserted at the ellipsis (...) in the generic style definition shown above. E.g., (using #rrggbb to specify a color, where rr are two hexadecimal digits specifying the color’s red component, gg two hexadecimal digits specifying the color’s green component, and bb two hexadecimal digits specifying the color’s blue component) specifying



    htmlstyle(body)(color: #rrggbb; background-color: #rrggbb)


    htmlstyle(h1)(color: blue; text-align: center)


    htmlstyle(h2)(color: green)

results in the element



    <style type="text/css">


        body {color: #rrggbb; background-color: #rrggbb;}


        h1 {color: blue; text-align: center;} 


        h2 {color: green;}


    </style>

The macros htmlheadopt and htmlstylesheet could also be used to put information into the head-section of an HTML document, but htmlheadopt is of a much more general nature, while htmlstylesheet refers to CSS elements stored in an external file. The macro attrib can be used to define inline styles.

The htmlstyle macro is only active in the preamble and is only interpreted for html conversions.
Refer to available CSS specifications (cf., http://www.w3schools.com/cssref/ for an overview of how CSS specifications are used, and which CSS specifications are available).

By default the internal style specification
figure {text-align: center;} img {vertical-align: center;}
is used. If this is not appropriate, specify nohtmlimgstyle() in the preamble.

htmlstylesheet(url)

Adds a <link rel="stylesheet" type="text/css" ...> element to the head section of an HTML document, using url in its href field. The argument url is not expanded, and should be plain HTML text, without surrounding quotes. The macro htmlheadopt can also be used to put information in the head-section of an HTML document, but htmlheadopt is of a much more general nature. This macro is only active in the preamble and is only interpreted for html conversions.

htmltag(tagname)(start)

Sets tagname as a HTML tag, enclosed by < and >. When start is zero, the tagname is prefixed with /. As not all html tags are available through predefined Yodl-macros (there are too many of them, some are used very infrequently, and you can easily define macros for the tags for which Yodl doesn’t offer predefined ones), the htmltag macro can be used to handle your own set of macros. In html the attrib macro is supported. E.g.,



    attrib(title="World Health Organization")htmltag(abbr)()WHO+htmltag(abbr)(0)

ifnewparagraph(truelist)(falselist)

The macro ifnewparagraph should be called from the PARAGRAPH macro, if defined. It will insert truelist if a new paragraph is inserted, otherwise falselist is inserted (e.g., following two consecutive calls of PARAGRAPH). This macro can be used to prevent the output of multiple blank lines.

includefile(file)

Includes file. The default extension .yo is supplied if necessary.

Furthermore, the includefile macro no longer defines a label. To define a label just before the file’s inclusion use lincludefile.

includeverbatim(file)

Include file into the output. No processing is done, file should be in preformatted form, e.g.:

whenhtml(includeverbatim(foo.html))

it()

Indicates an item in an itemized list. Items in it macros are arguments of itemization macros.

itdesc(itemname)(contents)

Starts an item and its description in a description list. Its name is itemname, the contents of the item is defined by contents. The itemname is defined by using the dit macro.

With html conversions the contents are surrounded by <dd> and </dd> tags, resulting in contents which are indented relative to the itemname. When the attrib macro is used it is applied to the itemname (dt-tags).

With other conversions the contents are quoted (as if using quote(contents)).

itemization(list)

Sets list as an itemizationd list. Use it() to indicate items in the list.

kindex()

Generate an index entry for LaTex() or texinfo k-indices. Its argument is the index entry. See also the [cfptv]vindex macro.

label(labelname)

Defines labelname as an anchor for a link command, or to stand for the last numbering of a section or figure in a ref command.

langle()

Character <

languagedutch()

Defines the Dutch-language specific headers. Active this macro via setlanguage(dutch).

languageenglish()

Defines the English-language specific headers. Active this macro via setlanguage(english).

languageportugese()

Defines the Portugese-language specific headers. Active this macro via setlanguage(portugese).

LaTeX()

The LaTeX symbol.

latexaddlayout(arg)

This macro is provided to add Yodl-interpreted text to your own LaTeX layout commands. The command is terminated with an end-of-line. See also the macro latexlayoutcmds()

latexcommand(cmd)

Writes cmd plus a white space to the output when converting to LaTeX. The cmd is not further expanded by Yodl.

latexdocumentclass(class)

Forces the LaTeX \documentclass{...} setting to class. Normally the class is defined by the macros article, report or book. This macro is an escape route in case you need to specify your own document class for LaTeX. This option is a modifier and must appear before the article, report or book macros.

latexlayoutcmds(NOTRANSs)

This macro is provided in case you want to put your own LaTeX layout commands into LaTeX output. The NOTRANSs are pasted right after the \documentclass stanza. The default is, of course, no local LaTeX commands. Note that this macro does not overrule my favorite LaTeX layout. Use nosloppyhfuzz() and standardlayout() to disable my favorite LaTeX layout.

latexoptions(options)

Set latex options: documentclass[options]. This command must appear before the document type is stated by article, report, etc..

latexpackage(options)(name)

Include latex package(s), a useful package is, e.g., epsf. This command must appear before the document type is stated by article, report, etc..

lchapter(label)(title)

Starts a new chapter in books or reports, setting a label at the beginning of the chapter.

letter(language)(date)(subject)(opening)(salutation)(author)

Starts a letter written in the indicated language. The date of the letter is set to `date’, the subject of the letter will be `subject’. The letter starts with `opening’. It is based on the `letter.cls’ document class definition. The macro is available for LaTeX only. Preamble command suggestions:

o

latexoptions(11pt)

o

a4enlarged()

o

letterreplyto(name)(address)(postalcode/city)

o

letterfootitem(phone)(number), maybe e-mail too.

o

letteradmin(yourdate)(yourref)

o

letterto(addressitem). Use a separate letterto() macro call for each new line of the address.

letteraddenda(type)(value)

Adds an addendum at the end of a letter. `type’ should be `bijlagen’, `cc’ or `ps’.

letteradmin(yourdate)(yourref)

Puts `yourletterfrom’ and `yourreference’ elements in the letter. If left empty, two dashes are inserted.

letterfootitem(name)(value)

Puts a footer at the bottom of letter-pages. Up to three will usually fit. LaTeX only.

letterreplyto(name)(address)(zip city)

Defines the `reply to’ address in LaTeX or txt-letters.

letterto(element)

Adds `element’ as an additional line to the address in LaTeX letters.

link(description)(labelname)

In HTML output a clickable link with the text description is created that points to the place where labelname is defined using the label macro, and attrib macro applies to the <a> tag. Using link is similar to url, except that a hyperlink is set pointing to a location in the same document. For output formats other than HTML, only the description appears.

lref(description)(labelname)

This macro is a combination of the ref and link macros. In HTML output a clickable link with the text description and the label value is created that points to the place where labelname is defined using the label macro, and attrib macro applies to the <a> tag. For output formats other than HTML, only the description and the label value appears.

lsect(label)(title)

Starts a new section, setting a label at the beginning of the section. In html attrib macro applies to the <h2> tag.

lsubsect(label)(title)

Starts a new subsection. Other sectioning commands are subsubsect and subsubsubsect. A label is added just before the subsection. In html attrib macro applies to the <h3> tag.

lsubsubsect(label)(title)

Starts a sub-subsection, a label is added just before the section In html attrib macro applies to the <h4> tag.

lsubsubsubsect(label)(title)

Starts a sub-sub-sub section. This level of sectioning is not numbered, in contrast to `higher’ sectionings. A label is added just before the subsubsubection.

lurl(locator)

An url described by its Locator. For small urls with readable addresses.

mailto(address)

Defines the default mailto address for HTML output. Must appear before the document type is stated by article, report, etc..

makeindex()

Make index for latex.

mancommand(cmd)

Writes cmd to the output when converting to man. The cmd is not further expanded by Yodl.

manpage(title)(section)(date)(source)(manual)

Starts a manual page document. The section argument must be a number, stating to which section the manpage belongs to. Most often used are commands (1), file formats (5) and macro packages (7). The sectioning commands in a manpage are not (n)sect etc., but manpage...(). The first section must be the manpagename, the last section must be the manpageauthor. The standard manpage for section 1 contains the following sections (in the given order): manpagename, manpagesynopsis, manpagedescription, manpageoptions, manpagefiles, manpageseealso, manpagediagnostics, manpagebugs, manpageauthor. Optional extra sections can be added with manpagesection. Standard manpageframes for several manpagesections are provided in /usr/local/share/yodl/manframes. YODL manual pages can be converted to groff, html, or plain ascii text formats.

manpageauthor()

Starts the AUTHOR entry in a manpage document. Must be the last section of a manpage.

manpagebugs()

Starts the BUGS entry in a manpage document.

manpagedescription()

Starts the DESCRIPTION entry in a manpage document.

manpagediagnostics()

Starts the DIAGNOSTICS entry in a manpage document.

manpagefiles()

Starts the FILES entry in a manpage document.

manpagename(name)(short description)

Starts the NAME entry in a manpage document. The short description is used by, e.g., the whatis database.

manpageoptions()

Starts the OPTIONS entry in a manpage document.

manpagesection(SECTIONNAME)

Inserts a non-required section named SECTIONNAME in a manpage document. This macro can be used to augment `standard’ manual pages with extra sections, e.g., EXAMPLES. Note that the name of the extra section should appear in upper case, which is consistent with the normal typesetting of manual pages.

manpageseealso()

Starts the SEE ALSO entry in a manpage document.

manpagesynopsis()

Starts the SYNOPSIS entry in a manpage document.

mbox()

Unbreakable box in LaTeX. Other formats may have different opitions on our unbreakable boxex.

metaC(text)

Put a line comment in the output.

metaCOMMENT(text)

Write format-specific comment to the output.

mscommand(cmd)

Writes cmd to the output when converting to ms. The cmd is not further expanded by Yodl.

nchapter(title)

Starts a chapter (in a book or report) without generating a number before the title and without placing an entry for the chapter in the table of contents. In html attrib macro applies to the <h1> tag.

nemail(name)(address)

Named email. A more consistent naming for url, lurl, email and nemail would be nice.

nl()

Forces a newline; i.e., breaks the current line in two.

nodeprefix(text)

Prepend text to node names, e.g.

nodeprefix(LilyPond) sect(Overview)

Currently used in texinfo descriptions only.

nodeprefix(text)

Prepend text to node names, e.g.

nodeprefix(LilyPond) sect(Overview)

Currently used in texinfo descriptions only.

nodetext(text)

Use text as description for the next node, e.g.

nodetext(The GNU Music Typesetter)chapter(LilyPond)

Currently used in texinfo descriptions only.

nohtmlfive()

Starting yodl 3.05 html-conversions by default use html5. This can be suppressed (in favor of using html4) by calling this macro. This macro merely suppresses writing the initial <!DOCTYPE html> to generated html files; it is only active in the preamble and is only interpreted for html conversions.

nohtmlimgstyle()

By default html-pages specify
(<style type="text/css" img {vertical-align: bottom;}></style>)
This macro suppresses this img CSS style specification. This macro is only active in the preamble and is only interpreted for html conversions.

nop(text)

Expand to text, to avoid spaces before macros e.g.: a. Although a+sups(2) should have the same effect.

nosloppyhfuzz()

By default, LaTeX output contains commands that cause it to shut up about hboxes that are less than 4pt overfull. When nosloppyhfuzz() appears before stating the document type, LaTeX complaints are `vanilla’.

notableofcontents()

Prevents the generation of a table of contents. This is default in, e.g., manpage and plainhtml documents. When present, this option must appear before stating the document type with article, report etc..

notitleclearpage()

Prevents the generation of a clearpage() instruction after the typesetting of title information. This instruction is default in all non article documents. When present, must appear before stating the document type with article, book or report.

notocclearpage()

With the LaTeX converter, no clearpage() instruction is inserted immediately beyond the document’s table of contents. The clearpage() instruction is default in all but the article document type. When present, must appear before stating the document type with article, book or report. With other converters than the LaTeX converter, it is ignored.

notransinclude(filename)

Reads filename and inserts it literally in the text not subject to macro expansion or character translation. No information is written either before or after the file’s contents, not even a newline.

noxlatin()

When used in the preamble, the LaTeX converter disables the inclusion of the file xlatin1.tex. Normally this file gets included in the LateX output files to ensure the conversion of high ASCII characters (like e) to LaTeX-understandable codes. (The file xlatin1.tex comes with the YODL distribution.)

nparagraph(title)

Starts a non-numbered paragraph (duh, corresponds to subparagraph in latex).

npart(title)

Starts a part in a book document, but without numbering it and without entering the title of the part in the table of contents. In html attrib macro applies to the <h1> tag.

nsect(title)

Starts a section, but does not generate a number before the title nor an entry in the table of contents. Further sectioning commands are nsubsect, nsubsubsect and nsubsubsubsect. In html attrib macro applies to the <h2> tag.

nsubsect(title)

Starts a non-numbered subsection. In html the attrib macro applies to the <h3> tag.

nsubsubsect(title)

Starts a non-numbered sub-sub section. In html attrib macro applies to the <p> tag.

nsubsubsect(title)

Starts a non-numbered sub-subsection.

paragraph(title)

Starts a paragraph. This level of sectioning is not numbered, in contrast to `higher’ sectionings (duh, corresponds to subparagraph in latex). In html attrib macro applies to the <p> tag.

part(title)

Starts a new part in a book document. In html attrib macro applies to the <h1> tag.

pindex()

Generate an index entry for LaTex() or texinfo p-indices. Its argument is the index entry. See also the [cftv]index macro.

plainhtml(title)

Starts a document for only a plain HTML conversion. Not available in other output formats. Similar to article, except that an author- and date field are not needed.

printindex()

Make index for texinfo (?).

quote(text)

Sets the text as a quotation. Usually, the text is indented, depending on the output format. In html attrib macro applies to the <blockquote> tag.

rangle()

Inserts the right angle character (>).

redef(macro)(nrofargs)(redefinition)

Defines macro macro to expand to redefinition. Similar to def, but any pre-existing definition is overruled. Use ARGx in the redefinition part to indicate where the arguments should be pasted. E.g., ARG1 places the first argument, ARG2 the second argument, etc...

redefinemacro(macro)(nrofargs)(redefinition)

ref(labelname)

Sets the reference for labelname. Use label to define a label.

report(title)(author)(date)

Starts a report type document. The top-level sectioning command in a report is chapter. In html the way the headings are displayed can be tuned using CSS id selector specifications: the title has id="title", the author id="author", and the date id="date".

roffcmd(dotcmd)(sameline)(secondline)(thirdline)

Sets a t/nroff command that starts with a dot, on its own line. The arguments are: dotcmd - the command itself, e.g., .IP; sameline - when not empty, set following the dotcmd on the same line; secondline - when not empty, set on the next line; thirdline - when not empty, set on the third line. Note that dotcmd and thirdline are not further expanded by YODL, the other arguments are.

row(contents)

The argument contents may contain a man-page alignment specification (only one specification can be entered per row), using setmanalign(). If omitted, the standard alignment is used. Furthermore it contains the contents of the elements of the row, using cell() or cells() macros. If cells() is used, setmanalign() should have been used too. In this macro call only the cell(), cells() and setmanalign() macros should be called. Any other macro call may produce unexpected results.

The row macro defines a counter XXcellnr that can be inspected and is incremented by predefined macros adding columns to a row. The counter is initially 0. Predefined macros adding columns to a row add the number of columns they add to the row inserting the contents of those columns. These macros rely on the correct value of this counter and any user-defined macros adding columns to table rows should correctly update XXcellnr. In html attrib macro applies to the <tr> tag.

rowline()

Sets a horizontal line over the full width of the table. See also columnline(). Use rowline() instead of a row() macro call to obtain a horizontal line-separator.

sc(text)

Set text in the tt (code) font, using small caps. In html the attrib macro is not supported, while the code section is embedded in a <div style="font-size: 90%"> section.

sect(title)

Starts a new section. In html attrib macro applies to the <h2> tag.

setaffilstring(name)

Defines name as the `affiliation information’ string, by default AFFILIATION INFORMATION. E.g., after setaffilstring(AFILIACION), YODL outputs this Spanish string to describe the affiliation information. Currently, it is relevant only for txt.

setauthorstring(name)

Defines name as the `Author information’ string, by default AUTHOR INFORMATION. E.g., after setauthorstring(AUTOR), YODL outputs this portuguese string to describe the author information. Currently, it is relevant only for txt.

setchapterstring(name)

Defines name as the `chapter’ string, by default Chapter. E.g., after setchapterstring(Hoofdstuk), YODL gains some measure of national language support for Dutch. Note that LaTeX support has its own NLS, this macro doesn’t affect the way LaTeX output looks.

setdatestring(name)

Defines name as the `date information’ string, by default DATE INFORMATION. E.g., after setdatestring(DATA), YODL outputs this portuguese string to describe the date information. Currently, it is relevant only for txt.

setfigureext(name)

Defines the name as the `figure’ extension. The extension should include the period, if used. E.g., use setfigureext(.ps) if the extensions of the figure-images should end in .ps

setfigurestring(name)

Defines the name as the `figure’ text, used e.g. in figure captions. E.g., after setfigurestring(Figuur), Yodl uses Dutch names for figures.

sethtmlfigureext(ext)

Defines the filename extension for HTML figures, defaults to .jpg. Note that a leading dot must be included in ext. The new extension takes effect starting with the following usage of the figure macro. It is only active in html, but otherwise acts identically as setfigureext().

htmlmetacharset(meta-charset)

Adds <meta charset="meta-charset"> to the head of html documents. By default <meta charset="UTF-8"> is used. This macro is only active in the preamble and is only interpreted for html conversions.

setincludepath(name)

Sets a new value of the include-path specification used when opening .yo files. A warning is issued when the path specification does not include a .: element. Note that the local directory may still be an element of the new include path, as the local directory may be the only or the last element of the specification. For these eventualities the new path specification is not checked.

setlanguage(name)

Installs the headers specific to a language. The argument must be the name of a language, whose headers have been set by a corresponding languageXXX() call. For example: languagedutch(). The language macros should set the names of the headers of the following elements: table of contents, affiliation, author, chapter, date, figure, part and title

setlatexalign(alignment)

This macro defines the table alignment used when setting tables in LaTeX. Use as many l (for left-alignment), r (for right alignment), and c (for centered-alignment) characters as there are columns in the table. See also table()

setlatexfigureext(ext)

Defines the filename extension for encapsulated PostScript figures in LaTeX, defaults to .ps. The dot must be included in t new extension ext. The new extension takes effect starting with a following usage of the figure macro. It is only active in LaTeX, but otherwise acts identically as setfigureext().

setlatexverbchar(char)

Set the char used to quote LaTeX \verb sequences

setmanalign(alignment)

This macro defines the table alignment used when setting tables used in man-pages (see tbl(1)). Use as many l (for left-alignment), r (for right alignment), and c (for centered-alignment) characters as there are columns in the table. Furthermore, s can be used to indicate that the column to its left is combined (spans into) the current column. Use this specification when cells spanning multiple columns are defined. Each row in a table which must be convertible to a manpage may contain a separate setmanalign() call. Note that neither rowline nor columnline requires setmanalign() specifications, as these macros define rows by themselves. It is the responsibility of the author to ensure that the number of alignment characters is equal to the number of columns of the table.

setpartstring(name)

Defines name as the `part’ string, by default Part. E.g., after setpartstring(Teil), Yodl identifies parts in the German way. Note that LaTeX output does its own national language support; this macro doesn’t affect the way LaTeX output looks.

setrofftab(x)

Sets the character separating items in a line of input data of a roff (manpage) table. By default it is set to ~. This separator is used internally, and needs only be changed (into some unique character) if the table elements themselves contain ~ characters.

setrofftableoptions(optionlist)

Set the options for tbl table, default: none. Multiple options should be separated by blanks, by default no option is used. From the tbl(1) manpage, the following options are selected for consideration:

o

center Centers the table (default is left-justified)

o

expand Makes the table as wide as the current line length

o

box Encloses the table in a box

o

allbox Encloses each item of the table in a box Note that starting with Yodl V 2.00 no default option is used anymore. See also setrofftab() which is used to set the character separating items in a line of input data.

settitlestring(name)

Defines name as the `title information’ string, by default TITLE INFORMATION. E.g., after settitlestring(TITEL), YODL outputs this Dutch string to describe the title information. Currently, it is relevant only for txt.

settocstring(name)

Defines name as the `table of contents’ string, by default Table of Contents. E.g., after settocstring(Inhalt), YODL identifies the table of contents in the German way. Note that LaTeX output does its own national language support; this macro doesn’t affect the way LaTeX output looks.

sgmlcommand(cmd)

Writes cmd to the output when converting to sgml. The cmd is not further expanded by Yodl.

sgmltag(tag)(onoff)

Similar to htmltag, but used in the SGML converter.

sloppyhfuzz(points)

By default, LaTeX output contains commands that cause it to shut up about hboxes that are less than 4pt overfull. When sloppyhfuzz() appears before stating the document type, LaTeX complaints occur only if hboxes are overfull by more than points.

standardlayout()

Enables the default LaTeX layout. When this macro is absent, then the first lines of paragraphs are not indented and the space between paragraphs is somewhat larger. The standardlayout() directive must appear before stating the document type as article, report, etc..

strong(contents)

In html and xml the contents are set between <strong> and </strong> tags. In html attrib macro applies to the <strong> tag.

subs(text)

Sets text in subscript in supporting formats. In html attrib macro applies to the <sub> tag.

subsect(title)

Starts a new subsection. Other sectioning commands are subsubsect and subsubsubsect. In html attrib macro applies to the <h3> tag.

subsubsect(title)

Starts a sub-subsection. In html attrib macro applies to the <h4> tag.

subsubsubsect(title)

Starts a sub-sub-sub-subsection. This level of sectioning is not numbered, in contrast to `higher’ sectionings.

sups(text)

Sets text in superscript in supporting formats In html attrib macro applies to the <sup> tag.

table(nColumns)(alignment)(Contents)

The table()-macro defines a table. Its first argument specifies the number of columns in the table. Its second argument specifies the (standard) alignment of the information within the cells as used by LaTeX or man/ms. Use l for left-alignment, c for centered-alignment and r for right alignment. Its third argument defines the contents of the table which are the rows, each containing column-specifications and optionally man/ms alignment definitions for this row.

See also the tableatt macro and the specialized setmanalign() macro.

tableatt(nColumns)(alignment)(Contents)

The tableatt()-macro defines a table. The last attrib call that was specified before using the tableatt()-macro is used to specify html attributes for the table. E.g., to center a table in html use



    attrib(style="margin-left:auto;margin-right:auto;")


    tableatt(...)

The macro’s first argument specifies the number of columns in the table. Its second argument specifies the (standard) alignment of the information within the cells as used by LaTeX or man/ms. Use l for left-alignment, c for centered-alignment and r for right alignment. Its third argument defines the contents of the table which are the rows, each containing column-specifications and optionally man/ms alignment definitions for this row.

See also the table macro and the specialized setmanalign() macro.

tcell(text)

Roff helper to set a table textcell, i.e., a paragraph. For LaTeX special table formatting p{} should be used.

telycommand(cmd)

Writes cmd to the output when converting to tely. The cmd is not further expanded by Yodl.

TeX()

The TeX symbol.

texinfocommand(cmd)

Writes cmd to the output when converting to texinfo. The cmd is not further expanded by Yodl.

tindex()

Generate an index entry for LaTex() or texinfo t-indices. Its argument is the index entry. See also the [cfpv]index macro.

titleclearpage()

Forces the generation of a clearpage() directive following the title of a document. This is already the default in books and reports, but can be overruled with notitleclearpage(). When present, must appear in the preamble; i.e., before the document type is stated with article, book or report.

tocclearpage()

With the LaTeX converter, a clearpage() directive if inserted, immediately following the document’s table of contents. This is already the default in all but the article document type, but it can be overruled by notocclearpage(). When present, it must appear in the preamble; i.e., before the document type is stated with article, book or report. With other converters than the LaTeX converter, it is ignored.

tt(text)

Sets text in teletype font, and prevents it from being expanded. For unbalanced parameter lists, use CHAR(40) to get ( and CHAR(41) to get ).

The tt macro does interpret character tables as well as any SUBST definitions. This is usually what is intended. In situations where this is unwelcome the ttbegin and ttend pair of macros can be used, between which the builtin commands PUSHSUBST, POPSUBST, NOEXPAND and/or NOTRANS can be used. E.g., to clearly show two hyphens in LaTeX teletype font use



    ttbegin()--ttend()

rather than



    tt(--)

Likewise, use ttbegin and ttend if the teletype text contains accented letters like e. To set this in teletype font use ttbegin()\"e+ttend().

In html the attrib macro applies to the <code> tag.

ttbegin()

Initiates text set in teletype font. Following the text to set in teletype font a ttend() macro should be called.

Usually the tt macro can be used instead of the ttbegin -- ttend combination. However, tt interprets character tables as well as SUBST definitions. In situations where this is unwelcome the ttbegin and ttend pair of macros can be used, between which builtin commands like PUSHSUBST, POPSUBST, NOEXPAND and/or NOTRANS can be used.

In html the attrib macro applies to the <code> tag.

ttend()

Ends text set in teletype font following ttbegin. Refer to the ttbegin macro’s description for details.

txtcommand(cmd)

Writes cmd to the output when converting to txt. The cmd is not further expanded by Yodl.

url(description)(locator)

In LaTeX documents the description is sent to the output. For HTML, a link is created with the descriptive text description and pointing to locator. The locator should be the full URL, including service; e.g, http://www.icce.rug.nl, but excluding the double quotes that are necessary in plain HTML. Use the macro link to create links within the same document. For other formats, something like description [locator] will appear. In html attrib macro applies to the <a> tag.

verb(text)

Sets text in verbatim mode: not subject to macro expansion or character table expansion, and starting with Yodl version 4.00.00: not using SUBST definitions. See also veborg, which does not provide the protection against SUBST definitions.

While converting Yodl-documents to target document types Yodl frequently uses the (not further documented) builtin function XXSUBST. In the unlikely event that the text XXSUBST(...) must be written in a document, the sequence



    XXSUBST+CHAR(40)...CHAR(41)

can be used.

The text that is passed as argument to the verb-macro appears literally on the output, usually in a teletype font (that depends on the output format). This macro is for larger chunks, e.g., listings.

When unbalanced parameter lists are required, use CHAR(40) to get ( and CHAR(41) to get ).

verbinclude(filename)

Reads filename and inserts it literally in the text, set in verbatim mode. not subject to macro expansion. The text appears literally on the output, usually in a teletype font (that depends on the output format). This macro is an alternative to verb(...), when the text to set in verbatim mode is better kept in a separate file.

verbinsert(args)

Passes args to yodlverbinsert(1), inserting its output into the converted file. This macro can be used to insert, e.g., a line-numbered indented file, or a labeled subsection of a file, into the file that’s currently being written by yodl. E.g,



    verbinsert(-ans4 file)          -- inserts file, showing line


                                       numbers, using a 4 blank-space


                                       character wide indentation.


    verbinsert(-ns4 //SECT file)    -- inserts the section of file, 


                                       labeled //SECT file, showing line


                                       numbers, using a 4 blank-space 


                                       character wide indentation.

verborg(text)

Sets text in verbatim mode: not subject to macro expansion or character table expansion, and starting with Yodl version 4.00.00: this macro replaces the previosly defined verb macro. The current verb macro surrounds this macro by PUSHSUBST and POPSUBST.

The text that is passed as argument to the verborg-macro appears literally on the output, albeit that SUBST definitions are processed, usually in a teletype font (that depends on the output format). This macro is for larger chunks, e.g., listings.

When unbalanced parameter lists are required, use CHAR(40) to get ( and CHAR(41) to get ).

verbpipe(command)(text)

Pipe text through command, but don’t expand the output.

vindex()

Generate an index entry for LaTex() or texinfo v-indices. Its argument is the index entry. See also the [cfkpt]index macro.

whenhtml(text)

Sends text to the output when in HTML conversion mode. The text is further expanded if necessary.

whenlatex(text)

Sends text to the output when in LATEX conversion mode. The text is further expanded if necessary.

whenman(text)

Sends text to the output when in MAN conversion mode. The text is further expanded if necessary.

whenms(text)

Sends text to the output when in MS conversion mode. The text is further expanded if necessary.

whensgml(text)

Sends text to the output when in SGML conversion mode. The text is further expanded if necessary.

whentely(text)

Sends text to the output when in TELY conversion mode. The text is further expanded if necessary.

whentexinfo(text)

Sends text to the output when in TEXINFO conversion mode. The text is further expanded if necessary.

whentxt(text)

Sends text to the output when in TXT conversion mode. The text is further expanded if necessary.

whenxml(text)

Sends text to the output when in XML conversion mode. The text is further expanded if necessary.

xit(itemname)

Starts an xml menu item where the file to which the menu refers to is the argument of the xit() macro. It should be used as argument to xmlmenu(), which has a 3rd argument: the default path prefixed to the xit() elements.

This macro is only available within the xml-conversion mode. The argument must be a full filename, including .xml extension, if applicable.

No .xml extension indicates a subdirectory, containing another sub-menu.

xmlcommand(cmd)

Writes cmd to the output when converting to xml. The cmd is not further expanded by Yodl.

xmlmenu(order)(title)(menulist)

Starts an xmlmenu. Use itemization() to define the items. Only available in xml conversion. The menutitle appears in the menu as the heading of the menu. The menulist is a series of xit() elements, containing the name of the file to which the menu refers as their argument (including a final /). Prefixed to evert every xit()-element is the value of XXdocumentbase.

Order is the the `order’ of the menu. If omitted, no order is defined.

xmlnewfile()

In XML output, starts a new file. All other formats are not affected. Note that you must take your own provisions to access the new file; say via links. Also, it’s safe to start a new file just befoore opening a new section, since sections are accessible from the clickable table of contents. The XML converter normally only starts new files prior to a chapter definition.

xmlsetdocumentbase(name)

Defines name as the XML document base. No default. Only interpreted with xml conversions. It is used with the figure and xmlmenu macros.

xmltag(tag)(onoff)

Similar to htmltag, but used in the XML converter.

OPTIONS

No options are relevant in respect to the macros.

FILES

The files in tmp/wip/macros define the converter’s macro packages. The scripts yodl2tex, yodl2html, yodl2man etc. perform the conversions.
