\versionid $Id$ \C{output} Halibut output formats This chapter describes each of Halibut's current \i{output formats}. It gives some general information about the format, and also describes all the \i{configuration directives} which are specific to that format. \H{output-text} Plain text This output format generates the document as a single \i{plain text} file. No table of contents or index is generated. The precise formatting of the text file can be controlled by a variety of configuration directives. They are listed in the following subsections. \S{output-text-file} Output file name \dt \I{\cw{\\cfg\{text-filename\}}}\cw{\\cfg\{text-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the text file. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--text} (see \k{running-options}). \S{output-text-dimensions} Indentation and line width This section describes the configuration directives which control the \i{horizontal dimensions} of the output text file: how much paragraphs are indented by and how long the lines are. \dt \I{\cw{\\cfg\{text-width\}}}\cw{\\cfg\{text-width\}\{}\e{width}\cw{\}} \dd Sets the \I{text width}width of the main part of the document, in characters. This width will be used for wrapping paragraphs and for centring titles (if you have asked for titles to be centred - see \k{output-text-headings}). This width does \e{not} include the left indentation set by \cw{\\cfg\{text-indent\}}; if you specify an indent of 8 and a width of 64, your maximum output line length will be 72. \dt \I{\cw{\\cfg\{text-indent\}}}\cw{\\cfg\{text-indent\}\{}\e{indent}\cw{\}} \dd Sets the left \i{indentation} for the document. If you set this to zero, your document will look like an ordinary text file as someone with a text editor might have written it; if you set it above zero, the text file will have a \i{margin} down the left in the style of some printed manuals, and you can then configure the section numbers to appear in this margin (see \k{output-text-headings}). \dt \I{\cw{\\cfg\{text-indent-code\}}}\cw{\\cfg\{text-indent-code\}\{}\e{indent}\cw{\}} \dd Specifies how many extra characters of indentation (on top of the normal left indent) should be given to \I{code paragraphs, indentation} code paragraphs. \dt \I{\cw{\\cfg\{text-list-indent\}}}\cw{\\cfg\{text-list-indent\}\{}\e{indent}\cw{\}} \dd Specifies how many extra spaces should be used to indent the bullet or number in a \I{bulletted list, indentation}bulletted or \I{numbered list, indentation}numbered \I{list, indentation}list. The actual body of the list item will be indented by this much \e{plus} the value configured by \cw{\\cfg\{text-listitem-indent\}}. \dt \I{\cw{\\cfg\{text-listitem-indent\}}}\cw{\\cfg\{text-listitem-indent\}\{}\e{indent}\cw{\}} \dd Specifies how many extra spaces should be used to indent the body of a list item, over and above the number configured in \cw{\\cfg\{text-list-indent\}}. \dt \I{\cw{\\cfg\{text-indent-preamble\}}}\cw{\\cfg\{text-indent-preamble\}\{}\e{boolean}\cw{\}} \dd When this is set to \c{true}, the document \i{preamble} (i.e. any paragraphs appearing before the first chapter heading) will be indented to the level specified by \cw{\\cfg\{text-indent\}}. If this setting is \c{false}, the document preamble will not be indented at all from the left margin. \S{output-text-headings} \ii{Configuring heading display} The directives in this section allow you to configure the appearance of the title, chapter and section headings in your text file. Several of the directives listed below specify the \i{alignment} of a heading. These alignment options have three possible values: \dt \i\c{left} \dd Align the heading to the very left of the text file (column zero). \dt \i\c{leftplus} \dd Align the section title to the left of the main display region (in other words, indented to the level specified by \cw{\\cfg\{text-indent\}}). The section \e{number} is placed to the left of that (so that it goes in the margin if there is room). \dt \i\c{centre} \dd Centre the heading. Also, several of the directives below specify how a title should be \I{underlining}underlined. The parameter to one of these directives should be either blank (\cw{\{\}}) or a piece of text which will be repeated to produce the underline. So you might want to specify, for example, \cw{\\text-title-underline\{=\}} but \cw{\\text-chapter-underline\{\-\}}. You can also specify more than one underline setting, and Halibut will choose the first one that the output character set supports. So, for example, you could write \cw{\\text-chapter-underline\{\\u203e\}\{\-\}}, and Halibut would use the Unicode \q{OVERLINE} character where possible and fall back to the ASCII minus sign otherwise. \dt \I{\cw{\\cfg\{text-title-align\}}}\cw{\\cfg\{text-title-align\}\{}\e{alignment}\cw{\}} \dd Specifies the alignment of the overall document title: \c{left}, \c{leftplus} or \c{centre}. \dt \I{\cw{\\cfg\{text-title-underline\}}}\cw{\\cfg\{text-title-underline\}\{}\e{underline-text}\cw{\}} \dd Specifies how the overall document title should be underlined. \dt \I{\cw{\\cfg\{text-chapter-align\}}}\cw{\\cfg\{text-chapter-align\}\{}\e{alignment}\cw{\}} \dd Specifies the alignment of chapter and appendix headings. \dt \I{\cw{\\cfg\{text-chapter-underline\}}}\cw{\\cfg\{text-chapter-underline\}\{}\e{underline-text}\cw{\}} \dd Specifies how chapter and appendix headings should be underlined. \dt \I{\cw{\\cfg\{text-chapter-numeric\}}}\cw{\\cfg\{text-chapter-numeric\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{true}, then chapter headings will not contain the word \q{Chapter} (or whatever other word you have defined in its place - see \k{input-sections} and \k{input-config}); they will just contain the chapter \e{number}, followed by the chapter title. If you set this to \c{false}, chapter headings will be prefixed by \q{Chapter} or equivalent. \dt \I{\cw{\\cfg\{text-chapter-shownumber\}}}\cw{\\cfg\{text-chapter-shownumber\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{false}, then chapter headings will \e{only} contain the chapter title: they will not contain the word \q{Chapter} (or whatever other word you have defined in its place), and neither will they contain the chapter number. If set to \c{false}, this overrides \cw{\\cfg\{text-chapter-numeric\}}. \dt \I{\cw{\\cfg\{text-chapter-suffix\}}}\cw{\\cfg\{text-chapter-suffix\}\{}\e{text}\cw{\}} \dd This specifies the suffix text to be appended to the chapter number, before displaying the chapter title. For example, if you set this to \cq{:\_}, then the chapter title might look something like \q{Chapter 2: Doing Things}. \dt \I{\cw{\\cfg\{text-section-align\}}}\cw{\\cfg\{text-section-align\}\{}\e{level}\cw{\}\{}\e{alignment}\cw{\}} \dd Specifies the alignment of section headings at a particular level. The \e{level} parameter specifies which level of section headings you want to affect: 0 means first-level headings (\c{\\H}), 1 means second-level headings (\c{\\S}), 2 means the level below that (\c{\\S2}), and so on. The \e{alignment} parameter is treated just like the other alignment directives listed above. \dt \I{\cw{\\cfg\{text-section-underline\}}}\cw{\\cfg\{text-section-underline\}\{}\e{level}\cw{\}\{}\e{underline-text}\cw{\}} \dd Specifies how to underline section headings at a particular level. \dt \I{\cw{\\cfg\{text-section-numeric\}}}\cw{\\cfg\{text-section-numeric\}\{}\e{level}\cw{\}\{}\e{boolean}\cw{\}} \dd Specifies whether section headings at a particular level should contain the word \q{Section} or equivalent (if \c{false}), or should be numeric only (if \c{true}). \dt \I{\cw{\\cfg\{text-section-shownumber\}}}\cw{\\cfg\{text-section-shownumber\}\{}\e{level}\cw{\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{false}, then section headings at the specified level will \e{only} contain the section title: they will not contain the word \q{Section} (or whatever other word you have defined in its place), and neither will they contain the section number. If set to \c{false}, this overrides \cw{\\cfg\{text-section-numeric\}}. \dt \I{\cw{\\cfg\{text-section-suffix\}}}\cw{\\cfg\{text-section-suffix\}\{}\e{level}\cw{\}\{}\e{text}\cw{\}} \dd Specifies the \I{suffix text, in section titles}suffix text to be appended to section numbers at a particular level, before displaying the section title. \S{output-text-characters} Configuring the characters used \dt \I\cw{\\cfg\{text-charset\}}\cw{\\cfg\{text-charset\}\{}\e{character set name}\cw{\}} \dd This tells Halibut what \i{character set} the output should be in. Any Unicode characters representable in this set will be output verbatim; any other characters will not be output and their \i{fallback text} (if any) will be used instead. \lcont{ The character set names are the same as for \cw{\\cfg\{input-charset\}} (see \k{input-config}). However, unlike \cw{\\cfg\{input-charset\}}, this directive affects the \e{entire} output; it's not possible to switch encodings halfway through. } \dt \I{\cw{\\cfg\{text-bullet\}}}\cw{\\cfg\{text-bullet\}\{}\e{text}\cw{\}}[\cw{\{}\e{text}...\cw{\}}] \dd This specifies the text which should be used as the \i{bullet} in bulletted lists. It can be one character (\cw{\\cfg\{text-bullet\}\{-\}}), or more than one (\cw{\\cfg\{text-bullet\}\{(*)\}}). \lcont{ Like \cw{\\cfg\{quotes\}} (see \k{input-config}), you can specify multiple possible options after this command, and Halibut will choose the first one which the output character set supports. For example, you might write \cw{\\cfg\{text-bullet\}\{\\u2022\}\{\\u00b7\}\{*\}}, in which case Halibut would use the Unicode \q{BULLET} character where possible, fall back to the ISO-8859-1 \q{MIDDLE DOT} if that wasn't available, and resort to the ASCII asterisk if all else failed. } \dt \I{\cw{\\cfg\{text-rule\}}}\cw{\\cfg\{text-rule\}\{}\e{text}\cw{\}}[\cw{\{}\e{text}...\cw{\}}] \dd This specifies the text which should be used for drawing \i{horizontal rules} (generated by \i\c{\\rule}; see \k{input-rule}). It can be one character, or more than one. The string you specify will be repeated to reach the required width, so you can specify something like \cq{-=} to get a rule that looks like \cw{-=-=-=}. \lcont{ Like \cw{\\cfg\{text-bullet\}}, you can specify multiple fallback options in this command. } \dt \I{\cw{\\cfg\{text-quotes\}}}\cw{\\cfg\{text-quotes\}\{}\e{open-quote}\cw{\}\{}\e{close-quote}\cw{\}}[\cw{\{}\e{open-quote}\cw{\}\{}\e{close-quote}...\cw{\}}] \dd This specifies a set of quote characters for the text backend, overriding any defined by \cw{\\cfg\{quotes\}}. It has the same syntax (see \k{input-config}). \lcont{ In this backend, these quotes will also be used to mark text enclosed in the \c{\\c} command (see \k{input-code}). } \dt \I{\cw{\\cfg\{text-emphasis\}}}\cw{\\cfg\{text-emphasis\}\{}\e{start-emph}\cw{\}\{}\e{end-emph}\cw{\}}[\cw{\{}\e{start-emph}\cw{\}\{}\e{end-emph}...\cw{\}}] \dd This specifies the characters which should be used to surround emphasised text (written using the \c{\\e} command; see \k{input-emph}). \lcont{ You should separately specify the start-emphasis and end-emphasis text, each of which can be more than one character if you want. Also, like \cw{\\cfg\{text-quotes\}}, you can specify multiple pairs of fallback options in this command, and Halibut will always use a matching pair. } \S{output-text-misc} Miscellaneous configuration options \dt \I{\cw{\\cfg\{text-list-suffix\}}}\cw{\\cfg\{text-list-suffix\}\{}\e{text}\cw{\}} \dd This text is appended to the number on a \i{numbered list} item (see \k{input-list-number}). So if you want to label your lists as \q{1)}, \q{2)} and so on, then you would write \cw{\\cfg\{text-list-suffix\}\{)\}}. \dt \I{\cw{\\cfg\{text-versionid\}}}\cw{\\cfg\{text-versionid\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{true}, \i{version ID paragraphs} (defined using the \i\c{\\versionid} command - see \k{input-blurb}) will be included at the bottom of the text file. If it is set to \c{false}, they will be omitted completely. \# FIXME: code indentation is configurable, therefore \quote \# indentation probably ought to be as well. \# FIXME: text-indent-* should be consistently named. \S{output-text-defaults} Default settings The \i{default settings} for Halibut's plain text output format are: \c \cfg{text-filename}{output.txt} \c \c \cfg{text-width}{68} \c \cfg{text-indent}{7} \c \cfg{text-indent-code}{2} \c \cfg{text-list-indent}{1} \c \cfg{text-listitem-indent}{3} \c \cfg{text-indent-preamble}{false} \c \c \cfg{text-title-align}{centre} \c \cfg{text-title-underline}{\u2550}{=} \c \c \cfg{text-chapter-align}{left} \c \cfg{text-chapter-underline}{\u203e}{-} \c \cfg{text-chapter-numeric}{false} \c \cfg{text-chapter-shownumber}{true} \c \cfg{text-chapter-suffix}{: } \c \c \cfg{text-section-align}{0}{leftplus} \c \cfg{text-section-underline}{0}{} \c \cfg{text-section-numeric}{0}{true} \c \cfg{text-section-shownumber}{0}{true} \c \cfg{text-section-suffix}{0}{ } \c \c \cfg{text-section-align}{1}{leftplus} \c \cfg{text-section-underline}{1}{} \c \cfg{text-section-numeric}{1}{true} \c \cfg{text-section-shownumber}{1}{true} \c \cfg{text-section-suffix}{1}{ } \c \c ... and so on for all section levels below this ... \e iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii \c \c \cfg{text-charset}{ASCII} \c \cfg{text-bullet}{\u2022}{-} \c \cfg{text-rule}{\u2500}{-} \c \cfg{text-quotes}{\u2018}{\u2019}{`}{'} \c \cfg{text-emphasis}{_}{_} \c \c \cfg{text-list-suffix}{.} \c \cfg{text-versionid}{true} \H{output-html} HTML This output format generates an \i{HTML} version of the document. By default, this will be in multiple files, starting with \c{Contents.html} and splitting the document into files by chapter and/or subsection. You can configure precisely how the text is split between HTML files using the configuration commands described in this section. In particular, you can configure Halibut to output one single HTML file instead of multiple ones. \I{\cw{\\cfg\{xhtml-anything\}}}Configuration directives with an \c{xhtml-} prefix are synonyms for those with an \c{html-} prefix. \S{output-html-file} Controlling the output file names \dt \I{\cw{\\cfg\{html-contents-filename\}}}\cw{\\cfg\{html-contents-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the top-level contents page. Since this is the first page a user ought to see when beginning to read the document, a good choice in many cases might be \c{index.html} (although this is not the default, for historical reasons). \dt \I{\cw{\\cfg\{html-index-filename\}}}\cw{\\cfg\{html-index-filename\}\{}\e{filename}\cw{\}} \dd Sets the file name in which to store the document's index. \dt \I{\cw{\\cfg\{html-template-filename\}}}\cw{\\cfg\{html-template-filename\}\{}\e{template}\cw{\}} \dd Provides a \i{template} to be used when constructing the file names of each chapter or section of the document. This template should contain at least one \i\e{formatting command}, in the form of a per cent sign followed by a letter. (If you need a literal per cent sign, you can write \c{%%}.) \lcont{ The formatting commands used in this template are: \dt \I{%N-upper}\c{%N} \dd Expands to the visible title of the section, with white space removed. So in a chapter declared as \cq{\\C\{fish\} Catching Fish}, this formatting command would expand to \cq{CatchingFish}. \dt \i\c{%n} \dd Expands to the type and number of the section, without white space. So in chapter 1 this would expand to \cq{Chapter1}; in section A.4.3 it would expand to \cq{SectionA.4.3}, and so on. If the section has no number (an unnumbered chapter created using \c{\\U}), this directive falls back to doing the same thing as \c{%N}. \dt \i\c{%b} \dd Expands to the number of the section, in a format suitable for an HTML fragment name. The first character of the section type is prepended to the section number. So in chapter 1 this would expand to \cq{C1}; in section A.4.3 it would expand to \cq{SA.4.3}, and so on. If the section has no number (an unnumbered chapter created using \c{\\U}), this directive falls back to doing the same thing as \c{%N}. \dt \i\c{%k} \dd Expands to the internal keyword specified in the section title. So in a chapter declared as \cq{\\C\{fish\} Catching Fish}, this formatting command would expand to \cq{fish}. If the section has no keyword (an unnumbered chapter created using \c{\\U}), this directive falls back to doing the same thing as \c{%N}. These formatting directives can also be used in the \cw{\\cfg\{html-template-fragment\}} configuration directive (see \k{output-html-misc}). } \dt \I{\cw{\\cfg\{html-single-filename\}}}\cw{\\cfg\{html-single-filename\}\{}\e{filename}\cw{\}} \dd Sets the file name in which to store the entire document, if Halibut is configured (using \c{\\cfg\{html-leaf-level\}\{0\}} to produce a single self-contained file. Both this directive \e{and} \c{\\cfg\{html-leaf-level\}\{0\}} are implicitly generated if you provide a file name parameter after the command-line option \i\c{--html} (see \k{running-options}). \S{output-html-split} Controlling the splitting into HTML files By default, the HTML output from Halibut is split into multiple files. Each file typically contains a single chapter or section and everything below it, unless subsections of that chapter are themselves split off into further files. Most files also contain a contents section, giving hyperlinks to the sections in the file and/or the sections below it. The configuration directives listed below allow you to configure the splitting into files, and the details of the contents sections. \dt \I{\cw{\\cfg\{html-leaf-level\}}}\cw{\\cfg\{html-leaf-level\}\{}\e{depth}\cw{\}} \dd This setting indicates the depth of section which should be given a \I{leaf file}\q{leaf} file (a file with no sub-files). So if you set it to 1, for example, then every chapter will be given its own HTML file, plus a top-level \i{contents file}. If you set this to 2, then each chapter \e{and} each \c{\\H} section will have a file, and the chapter files will mostly just contain links to their \i{sub-file}s. \lcont{ If you set this option to zero, then the whole document will appear in a single file. If you do this, Halibut will call that file \i\c{Manual.html} instead of \i\c{Contents.html} by default. This option is automatically set to zero if you provide a file name parameter after the command-line option \i\c{--html} (see \k{running-options}), because you have specified a single file name and so Halibut assumes you want the whole document to be placed in that file. You can also specify the special name \c{infinity} (or \c{infinite} or \c{inf}) if you want to ensure that \e{every} section and subsection ends up in a separate file no matter how deep you go. } \dt \I{\cw{\\cfg\{html-contents-depth\}}}\cw{\\cfg\{html-contents-depth\}\{}\e{level}\cw{\}\{}\e{depth}\cw{\}} \dd This directive allows you to specify how \I{depth of contents}deep any contents section in a particular level of file should go. \lcont{ The \e{level} parameter indicates which level of contents section you are dealing with. 0 denotes the main contents section in the topmost file \c{Contents.html}; 1 denotes a contents section in a chapter file; 2 is a contents section in a file containing a \c{\\H} heading, and so on. The \e{depth} parameter indicates the maximum depth of heading which will be shown in this contents section. Again, 1 denotes a chapter, 2 is a \c{\\H} heading, 3 is a \c{\\S} heading, and so on. So, for example: \cw{\\cfg\{html-contents-depth\}\{1\}\{3\}} instructs Halibut to put contents links in chapter files for all sections down to \c{\\S} level, but not to go into any more detail than that. For backwards compatibility, the alternative syntax \cw{\\cfg\{html-contents-depth-}\e{level}\cw{\}\{}\e{depth}\cw{\}} is also supported. } \dt \I{\cw{\\cfg\{html-leaf-contains-contents\}}}\cw{\\cfg\{html-leaf-contains-contents\}\{}\e{boolean}\cw{\}} \dd If you set this to \c{true}, then each leaf file will contain its own contents section which summarises the text within it. \dt \I{\cw{\\cfg\{html-leaf-smallest-contents\}}}\cw{\\cfg\{html-leaf-smallest-contents\}\{}\e{number}\cw{\}} \dd Contents sections in leaf files are not output at all if they contain very few entries (on the assumption that it just isn't worth bothering). This directive configures the minimum number of entries required in a leaf contents section to make Halibut bother generating it at all. \S{output-html-html} Including pieces of your own HTML The directives in this section allow you to supply pieces of \I{HTML}\i{verbatim HTML} code, which will be included in various parts of the output files. Note that none of Halibut's usual character set translation is applied to this code; it is assumed to already be in a suitable encoding for the target HTML files. \dt \I{\cw{\\cfg\{html-head-end\}}}\cw{\\cfg\{html-head-end\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is placed at the end of the \i\cw{} section of each output HTML file. So this is a good place to put, for example, a link to a \i{CSS} \i{stylesheet}. \dt \I{\cw{\\cfg\{html-local-head\}}}\cw{\\cfg\{html-local-head\}\{}\e{HTML text}\cw{\}} \dd This configuration directive is local: you specify it within a document section, and it acts on that section only. \lcont{ The text you provide in this directive is placed at the end of the \i\cw{} section of whichever output HTML file contains the section in which the directive was placed. You can specify this directive multiple times in multiple sections if you like. This directive is particularly useful for constructing \i{MacOS on-line help}, which is mostly normal HTML but which requires a special \i\cw{} tag in the topmost source file. You can arrange this by placing this configuration directive in the preamble or the introduction section, something like this: \c \cfg{html-local-head}{} } \dt \I{\cw{\\cfg\{html-body-tag\}}}\cw{\\cfg\{html-body-tag\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is used in place of the \i\cw{} tag in each output file. So if you wanted to define a \i{background colour}, for example, you could write \cw{\\cfg\{html-body-tag\}\{\}}. \dt \I{\cw{\\cfg\{html-body-start\}}}\cw{\\cfg\{html-body-start\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is placed at the beginning of the \i\cw{} section of each output HTML file. So if you intend your HTML files to be part of a web site with a standard \i{house style}, and the style needs a \i{header} at the top of every page, this is where you can add that header. \dt \I{\cw{\\cfg\{html-body-end\}}}\cw{\\cfg\{html-body-end\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is placed at the end of the \i\cw{} section of each output HTML file, before any address section. So if you intend your HTML files to be part of a web site with a standard \i{house style}, and the style needs a \i{footer} at the bottom of every page, this is where you can add that footer. \dt \I{\cw{\\cfg\{html-address-start\}}}\cw{\\cfg\{html-address-start\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is placed at the beginning of the \i\cw{
} section at the bottom of each output HTML file. This might be a good place to put authors' \i{contact details}, for example. \dt \I{\cw{\\cfg\{html-address-end\}}}\cw{\\cfg\{html-address-end\}\{}\e{HTML text}\cw{\}} \dd The text you provide in this directive is placed at the end of the \i\cw{
} section at the bottom of each output HTML file, after the version IDs (if present). \dt \I{\cw{\\cfg\{html-navigation-attributes\}}}\cw{\\cfg\{html-navigation-attributes\}\{}\e{HTML attributes}\cw{\}} \dd The text you provide in this directive is included inside the \cw{

} tag containing the \i{navigation links} at the top of each page (\i{\q{Previous}} / \i{\q{Contents}} / \i{\q{Next}}). So if you wanted the navigation links to have a particular CSS style, you could write \cw{\\cfg\{html-navigation-attributes\}\{class="foo"\}}, and the navigation-links paragraph would then begin with the tag \cw{

}. \S{output-html-headings} \ii{Configuring heading display} \dt \I{\cw{\\cfg\{html-chapter-numeric\}}}\cw{\\cfg\{html-chapter-numeric\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{true}, then chapter headings will not contain the word \q{Chapter} (or whatever other word you have defined in its place - see \k{input-sections} and \k{input-config}); they will just contain the chapter \e{number}, followed by the chapter title. If you set this to \c{false}, chapter headings will be prefixed by \q{Chapter} or equivalent. \dt \I{\cw{\\cfg\{html-chapter-shownumber\}}}\cw{\\cfg\{html-chapter-shownumber\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{false}, then chapter headings will \e{only} contain the chapter title: they will not contain the word \q{Chapter} (or whatever other word you have defined in its place), and neither will they contain the chapter number. If set to \c{false}, this overrides \cw{\\cfg\{html-chapter-numeric\}}. \dt \I{\cw{\\cfg\{html-chapter-suffix\}}}\cw{\\cfg\{html-chapter-suffix\}\{}\e{text}\cw{\}} \dd This specifies the suffix text to be appended to the chapter number, before displaying the chapter title. For example, if you set this to \cq{:\_}, then the chapter title might look something like \q{Chapter 2: Doing Things}. \dt \I{\cw{\\cfg\{html-section-numeric\}}}\cw{\\cfg\{html-section-numeric\}\{}\e{level}\cw{\}\{}\e{boolean}\cw{\}} \# {level} can be omitted (defaults to 0). Is this intentional? \dd Specifies whether section headings at a particular level should contain the word \q{Section} or equivalent (if \c{false}), or should be numeric only (if \c{true}). The \e{level} parameter specifies which level of section headings you want to affect: 0 means first-level headings (\c{\\H}), 1 means second-level headings (\c{\\S}), 2 means the level below that (\c{\\S2}), and so on. \dt \I{\cw{\\cfg\{html-section-shownumber\}}}\cw{\\cfg\{html-section-shownumber\}\{}\e{level}\cw{\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{false}, then section headings at the specified level will \e{only} contain the section title: they will not contain the word \q{Section} (or whatever other word you have defined in its place), and neither will they contain the section number.

In order to do this, you also need some auxiliary files: a project file, and (probably) a contents file and an index file. Halibut can optionally generate those as well. To enable the generation of MS HTML Help auxiliary files, use the following configuration directives: \dt \I\cw{\\cfg\{html-mshtmlhelp-project\}}\cw{\\cfg\{html-mshtmlhelp-project\}\{}\e{filename}\cw{\}} \dd Instructs Halibut to output an HTML Help project file with the specified name. You will almost certainly want the filename to end in the extension \c{.hhp} (although Halibut will not enforce this). If you use this option, you must also use the \cw{html-mshtmlhelp-chm} option to specify the desired name of the compiled help file. \dt \I\cw{\\cfg\{html-mshtmlhelp-chm\}}\cw{\\cfg\{html-mshtmlhelp-chm\}\{}\e{filename}\cw{\}} \dd Specifies the desired name of the compiled HTML Help file. You will almost certainly want this to have the extension \c{.chm} (although Halibut will not enforce this). The name you specify here will be written into the help project file. If you specify this option, you must also use the \cw{html-mshtmlhelp-project} option to request a help project file in the first place. \dt \I\cw{\\cfg\{html-mshtmlhelp-contents\}}\cw{\\cfg\{html-mshtmlhelp-contents\}\{}\e{filename}\cw{\}} \dd Instructs Halibut to output an HTML Help contents file with the specified name, and refer to it in the help project file. You will almost certainly want the filename to end in the extension \c{.hhc} (although Halibut will not enforce this). This option will be ignored if you have not also specified a help project file. \lcont{ Creating a contents file like this causes the HTML Help viewer to display a contents tree in the pane to the left of the main text window. You can choose to generate an HTML Help project without this feature, in which case the user will still be able to navigate around the document by using the ordinary internal links in the HTML files themselves just as if it were a web page. However, using a contents file is recommended. } \dt \I\cw{\\cfg\{html-mshtmlhelp-index\}}\cw{\\cfg\{html-mshtmlhelp-index\}\{}\e{filename}\cw{\}} \dd Instructs Halibut to output an HTML Help index file with the specified name, and refer to it in the help project file. You will almost certainly want the filename to end in the extension \c{.hhk} (although Halibut will not enforce this). This option will be ignored if you have not also specified a help project file. \lcont{ Specifying this option suppresses the generation of an HTML-based index file (see \cw{\\cfg\{html-index-filename\}} in \k{output-html-file}). Creating an index file like this causes the HTML Help viewer to provide a list of index terms in a pane to the left of the main text window. You can choose to generate an HTML Help project without this feature, in which case a conventional HTML index will be generated instead (assuming you have any index terms at all defined) and the user will still be able to use that. However, using an index file is recommended. Halibut will not output an index file at all, or link to one from the help project file, if your document contains no index entries. } If you use the above options, Halibut will output a help project file which you should be able to feed straight to the command-line MS HTML Help compiler (\cw{HHC.EXE}), or load into the MS HTML Help Workshop (\cw{HHW.EXE}). You may also wish to alter other HTML configuration options to make the resulting help file look more like a help file and less like a web page. A suggested set of additional configuration options for HTML Help is as follows: \b \cw{\\cfg\{html-leaf-level\}\{infinite\}}, because HTML Help works best with lots of small files (\q{topics}) rather than a few large ones. In particular, the contents and index mechanisms can only reference files, not subsections within files. \b \cw{\\cfg\{html-leaf-contains-contents\}\{false\}}, to suppress the contents list above the main text of each bottom-level file. \b \cw{\\cfg\{html-suppress-navlinks\}\{true\}}, because HTML Help has its own navigation facilities and it looks a bit strange to duplicate them. \b \cw{\\cfg\{html-suppress-address\}\{true\}}, because the \cw{<ADDRESS>} section makes less sense in a help file than it does on a web page. \S{output-html-defaults} Default settings The \i{default settings} for Halibut's HTML output format are: \c \cfg{html-contents-filename}{Contents.html} \c \cfg{html-index-filename}{IndexPage.html} \c \cfg{html-template-filename}{%n.html} \c \cfg{html-single-filename}{Manual.html} \c \c \cfg{html-leaf-level}{2} \c \cfg{html-leaf-contains-contents}{false} \c \cfg{html-leaf-smallest-contents}{4} \c \cfg{html-contents-depth}{0}{2} \c \cfg{html-contents-depth}{1}{3} \c ... and so on for all section levels below this ... \e iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii \c \c \cfg{html-head-end}{} \c \cfg{html-body-tag}{<body>} \c \cfg{html-body-start}{} \c \cfg{html-body-end}{} \c \cfg{html-address-start}{} \c \cfg{html-address-end}{} \c \cfg{html-navigation-attributes}{} \c \c \cfg{html-chapter-numeric}{false} \c \cfg{html-chapter-shownumber}{true} \c \cfg{html-chapter-suffix}{: } \c \c \cfg{html-section-numeric}{0}{true} \c \cfg{html-section-shownumber}{0}{true} \c \cfg{html-section-suffix}{0}{ } \c \c \cfg{html-section-numeric}{1}{true} \c \cfg{html-section-shownumber}{1}{true} \c \cfg{html-section-suffix}{1}{ } \c \c ... and so on for all section levels below this ... \e iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii \c \c \cfg{html-preamble-text}{Preamble} \c \cfg{html-contents-text}{Contents} \c \cfg{html-index-text}{Index} \c \cfg{html-title-separator}{ - } \c \cfg{html-index-main-separator}{: } \c \cfg{html-index-multiple-separator}{, } \c \cfg{html-pre-versionid}{[} \c \cfg{html-post-versionid}{]} \c \cfg{html-nav-prev-text}{Previous} \c \cfg{html-nav-next-text}{Next} \c \cfg{html-nav-up-text}{Up} \c \cfg{html-nav-separator}{ | } \c \c \cfg{html-output-charset}{ASCII} \c \cfg{html-restrict-charset}{UTF-8} \c \cfg{html-quotes}{\u2018}{\u2019}{"}{"} \c \c \cfg{html-version}{html4} \c \cfg{html-template-fragment}{%b} \c \cfg{html-versionid}{true} \c \cfg{html-rellinks}{true} \c \cfg{html-suppress-navlinks{false} \c \cfg{html-suppress-address}{false} \c \cfg{html-author}{} \c \cfg{html-description}{} \H{output-whlp} Windows Help This output format generates data that can be used by the \i{Windows Help} program \cw{WINHLP32.EXE}. There are two actual files generated, one ending in \c{.hlp} and the other ending in \c{.cnt}. Note that as of 2006, MS is discontinuing the Windows Help format in favour of the newer HTML Help format (\c{.chm} files). Halibut is not currently able to generate \c{.chm} files directly, but its HTML back end can write out project files suitable for use as input to the MS HTML Help compiler. See \k{output-html-mshtmlhelp} for more information on this. Currently, the Windows Help output is hardcoded to be in the \q{\i{Win1252}} character set. (If anyone knows how character sets are encoded in Windows Help files, we'd appreciate help.) The Windows Help output format supports the following configuration directives: \S{output-whlp-file} Output file name \dt \I{\cw{\\cfg\{winhelp-filename\}}}\cw{\\cfg\{winhelp-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the help file. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--winhelp} (see \k{running-options}). \lcont{ Your output file name should end with \c{.hlp}; if it doesn't, Halibut will append it. Halibut will also generate a contents file (ending in \c{.cnt}) alongside the file name you specify. } \S{output-whlp-characters} Configuring the characters used \dt \I{\cw{\\cfg\{winhelp-bullet\}}}\cw{\\cfg\{winhelp-bullet\}\{}\e{text}\cw{\}}[\cw{\{}\e{text}\cw{\}}...] \dd Specifies the text to use as the \i{bullet} in bulletted lists.

Topic names can be used by the program invoking \cw{WINHELP.EXE} to jump straight to a particular section. So you can use this for \i{context-sensitive help}. \lcont{ For example, if you used this directive in a particular section: \c \cfg{winhelp-topic}{savingfiles} then a Windows application could invoke Windows Help to jump to that particular section in the help file like this: \c WinHelp(hwnd, "mydoc.hlp", HELP_COMMAND, \c (DWORD)"JI(`',`savingfiles')"); You can use this configuration directive many times, in many different subsections of your document, in order to define a lot of different help contexts which you can use in this way. } \S{output-whlp-defaults} Default settings The \i{default settings} for the Windows Help output format are: \c \cfg{winhelp-filename}{output.hlp} \c \c \cfg{winhelp-bullet}{\u2022}{-} \c \cfg{winhelp-quotes}{\u2018}{\u2019}{"}{"} \c \c \cfg{winhelp-contents-titlepage}{Title page} \c \cfg{winhelp-section-suffix}{: } \c \cfg{winhelp-list-suffix}{.} and no \c{\\cfg\{winhelp-topic\}} directives anywhere. \H{output-man} Unix \cw{man} pages This output format generates a Unix \i{\cw{man} page}. That is to say, it generates \i\c{nroff} input designed to work with the \c{-mandoc} macro package. The available configuration options for this format are as follows: \S{output-man-file} Output file name \dt \I{\cw{\\cfg\{man-filename\}}}\cw{\\cfg\{man-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the man page. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--man} (see \k{running-options}). \S{output-man-identity} Configuring headers and footers \dt \I{\cw{\\cfg\{man-identity\}}}\cw{\\cfg\{man-identity\}\{}\e{text}\cw{\}\{}\e{text...}\cw{\}} \dd This directive is used to generate the initial \i{\c{.TH} directive} that appears at the top of a \cw{man} page. It expects to be followed by some number of brace pairs containing text, which will be used in the \i{headers} and \i{footers} of the formatted output. \lcont{ A traditional order for the arguments appears to be: \n The name of the program. \n The (numeric) manual section. \n The date that the \cw{man} page was written. \n The name of any containing suite of which the program is a part. \n The name of the \i{author} of the \cw{man} page. For example, a typical \cw{man} page might contain \c \cfg{man-identity}{make-foo}{1}{June 2003}{foo-utils}{Fred \c Bloggs} } \S{output-man-headings} Configuring heading display \dt \I{\cw{\\cfg\{man-headnumbers\}}}\cw{\\cfg\{man-headnumbers\}\{}\e{boolean}\cw{\}} \dd If this is set to \c{true}, then \i{section headings} in the \cw{man} page will have their \i{section numbers} displayed as usual. If set to \c{false}, the section numbers will be omitted. (\cw{man} pages traditionally have section names such as \q{SYNOPSIS}, \q{OPTIONS} and \q{BUGS}, and do not typically number them, so \c{false} is the setting which conforms most closely to normal \cw{man} style.) \dt \I{\cw{\\cfg\{man-mindepth\}}}\cw{\\cfg\{man-mindepth\}\{}\e{depth}\cw{\}} \dd If this is set to a number greater than 0, then section headings \e{higher} than the given depth will not be displayed. If it is set to zero, all section headings will be displayed as normal. \lcont{ The point of this is so that you can use the same Halibut input file to generate a quick-reference \cw{man} page for a program, \e{and} to include that \cw{man} page as an appendix in your program's full manual. If you are to include the \cw{man} page as an appendix, then the internal headings within the page will probably need to be at \c{\\H} or \c{\\S} level; therefore, when you format that input file on its own to create the \cw{man} page itself, you will need to have defined a \c{\\C} and possibly a \c{\\H} heading beforehand, which you don't want to see displayed. Here's an example. You might have a file \c{appendix.but}, which simply says \c \A{manpages} \cw{man} pages for the Foo tool suite \c \c \cfg{man-mindepth}{2} Then you have a file \c{make-foo.but}, and probably others like it as well, each of which looks something like this: \c \cfg{man-identity}{make-foo}{1}{June 2003}{foo-utils}{Fred \c Bloggs} \c \c \H{man-foo} \cw{man} page for \c{make-foo} \c \c \S{man-foo-name} NAME \c \c \c{make-foo} - create Foo files for the Foo tool suite \c \c \S{man-foo-synopsis} SYNOPSIS \c \c ... and so on ... \e iiiiiiiiiiiiiiiii So when you're generating your main manual, you can include \c{appendix.but} followed by \c{make-foo.but} and any other \cw{man} pages you have, and your \cw{man} pages will be formatted neatly as part of an appendix. Then, in a separate run of Halibut, you can just do \c halibut appendix.but make-foo.but and this will generate a \cw{man} page \c{output.1}, in which the headings \q{\cw{man} pages for the Foo tool suite} and \q{\cw{man} page for \c{make-foo}} will not be displayed because of the \c{man-mindepth} directive. So the first visible heading in the output \cw{man} page will be \q{NAME}, exactly as a user would expect. } \S{output-man-characters} Configuring the characters used \dt \I{\cw{\\cfg\{man-charset\}}}\cw{\\cfg\{man-charset\}\{}\e{character set}\cw{\}} \dd Specifies what character set the output should be in, similarly to \cw{\\cfg\{text-charset\}} (see \k{output-text-characters}). \# FIXME: you're probably on your own in making sure that it's sensible to output man pages in that charset. \dt \I{\cw{\\cfg\{man-bullet\}}}\cw{\\cfg\{man-bullet\}\{}\e{text}\cw{\}}[\cw{\{}\e{text}\cw{\}}...] \dd Specifies the text to use as the \i{bullet} in bulletted lists.

There are typically multiple output files: a primary file whose name usually ends in \c{.info}, and one or more subsidiary files whose names have numbers on the end, so that they end in \c{.info-1}, \c{.info-2} and so on. Alternatively, this output format can be configured to output a single large file containing the whole document. The Info output format supports the following configuration directives: \S{output-info-file} Controlling the output filenames \dt \I{\cw{\\cfg\{info-filename\}}}\cw{\\cfg\{info-filename\}\{}\e{filename}\cw{\}} \dd Sets the output file name in which to store the Info file. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--info} (see \k{running-options}). \lcont{ The suffixes \c{-1}, \c{-2}, \c{-3} and so on will be appended to your output file name to produce any subsidiary files required. Note that Info files refer to their own names internally, so these files cannot be \I{renaming Info files}renamed after creation and remain useful. } \dt \I{\cw{\\cfg\{info-max-file-size\}}}\cw{\\cfg\{info-max-file-size\}\{}\e{bytes}\cw{\}} \dd Sets the preferred \i{maximum file size} for each subsidiary file. As a special case, if you set this to zero, there will be no subsidiary files and the whole document will be placed in a single self-contained output file. (However, note that this file can still not be renamed usefully.) \lcont{ The preferred maximum file size is only a guideline. Halibut may be forced to exceed it if a single section of the document is larger than the maximum size (since individual Info nodes may not be split between files). } \S{output-info-dimensions} Indentation and line width \dt \I{\cw{\\cfg\{info-width\}}}\cw{\\cfg\{info-width\}\{}\e{width}\cw{\}} \dd Sets the \I{text width}width of the main part of the document, in characters.

The \e{level} parameter specifies which level of section headings you want to affect: 0 means first-level headings (\c{\\H}), 1 means second-level headings (\c{\\S}), 2 means the level below that (\c{\\S2}), and so on. \S{output-info-characters} Controlling the characters used \dt \I{\cw{\\cfg\{info-charset\}}}\cw{\\cfg\{info-charset\}\{}\e{character set}\cw{\}} \dd Specifies what character set the output should be in, similarly to \cw{\\cfg\{text-charset\}} (see \k{output-text-characters}). \# FIXME: if you try sufficiently hard, you can probably find an output encoding that will break the info format by trampling on its special characters. So either don't do that, or tell us what we should do about it. \dt \I{\cw{\\cfg\{info-bullet\}}}\cw{\\cfg\{info-bullet\}\{}\e{text}\cw{\}}[\cw{\{}\e{text}\cw{\}}...] \dd Specifies the text to use as the \i{bullet} in bulletted lists.

This mechanism is used to automatically generate the \i{\c{dir} file} at the root of a Unix system's Info collection. \lcont{ The parameters to this directive are: \dt \e{section} \dd Specifies the section of the \c{dir} file in which you want your document referenced. For example, \q{Development}, or \q{Games}, or \q{Miscellaneous}. \dt \e{short name} \dd Specifies a short name for the directory entry, which will appear at the start of the menu line. \dt \e{long name} \dd Specifies a long name for the directory entry, which will appear at the end of the menu line. \dt \e{keyword} \dd This parameter is optional. If it is present, then the directory entry will cause a jump to a particular subsection of your document, rather than starting at the top. The subsection will be the one referred to by the given keyword (see \k{input-sections} for details about assigning keywords to document sections). For example, in a document describing many game programs, the configuration directive \c \cfg{info-dir-entry}{Games}{Chess}{Electronic chess \c game}{chess} might produce text in the \c{dir} file looking something like this: \c Games \c * Chess: (mygames)Chapter 3. Electronic chess game if the output file were called \c{mygames.info} and the keyword \c{chess} had been used to define Chapter 3 of the document. } \S{output-info-defaults} Default settings The \i{default settings} for the Info output format are: \c \cfg{info-filename}{output.info} \c \cfg{info-max-file-size}{65536} \c \c \cfg{info-width}{70} \c \cfg{info-indent-code}{2} \c \cfg{info-index-width}{40} \c \cfg{info-list-indent}{1} \c \cfg{info-listitem-indent}{3} \c \c \cfg{info-section-suffix}{: } \c \cfg{info-title-underline}{*} \c \cfg{info-chapter-underline}{=} \c \cfg{info-section-underline}{0}{-} \c \cfg{info-section-underline}{1}{.} \c \cfg{info-section-underline}{2}{.} \c ... and so on for all section levels below this ... \e iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii \c \c \cfg{info-charset}{ASCII} \c \cfg{info-bullet}{\u2022}{-} \c \cfg{info-rule}{\u2500}{-} \c \cfg{info-quotes}{\u2018}{\u2019}{`}{'} \c \cfg{info-emphasis}{_}{_} \c \c \cfg{info-list-suffix}{.} and no \cw{\\cfg\{info-dir-entry\}} directives. \H{output-paper} Paper formats These output formats (currently PDF and PostScript) generate printable manuals. As such, they share a number of configuration directives. \S{output-pdf} \i{PDF} This output format generates a printable manual in PDF format. In addition, it uses some PDF interactive features to provide an outline of all the document's sections and clickable cross-references between sections. There is one configuration option specific to PDF: \dt \I{\cw{\\cfg\{pdf-filename\}}}\cw{\\cfg\{pdf-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the PDF file. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--pdf} (see \k{running-options}). The \i{default settings} for the PDF output format are: \c \cfg{pdf-filename}{output.pdf} \S{output-ps} \i{PostScript} This output format generates a printable manual in PostScript format. This should look exactly identical to the PDF output (see \k{output-ps}), and uses \i\c{pdfmark} to arrange that if converted to PDF it will contain the same interactive features. There is one configuration option specific to PostScript: \dt \I{\cw{\\cfg\{ps-filename\}}}\cw{\\cfg\{ps-filename\}\{}\e{filename}\cw{\}} \dd Sets the \i{output file name} in which to store the PostScript file. This directive is implicitly generated if you provide a file name parameter after the command-line option \i\c{--ps} (see \k{running-options}). The \i{default settings} for the PostScript output format are: \c \cfg{ps-filename}{output.ps} \S{output-paper-dimensions} Configuring layout and \i{measurements} All measurements are in PostScript \i{points} (72 points to the inch). \S2{output-paper-pagesize} Page properties \dt \I{\cw{\\cfg\{paper-page-width\}}}\cw{\\cfg\{paper-page-width\}\{}\e{points}\cw{\}} \dt \I{\cw{\\cfg\{paper-page-height\}}}\cw{\\cfg\{paper-page-height\}\{}\e{points}\cw{\}} \dd Specify the absolute limits of the paper. \dt \I{\cw{\\cfg\{paper-left-margin\}}}\cw{\\cfg\{paper-left-margin\}\{}\e{points}\cw{\}} \dt \I{\cw{\\cfg\{paper-top-margin\}}}\cw{\\cfg\{paper-top-margin\}\{}\e{points}\cw{\}} \dt \I{\cw{\\cfg\{paper-right-margin\}}}\cw{\\cfg\{paper-right-margin\}\{}\e{points}\cw{\}} \dt \I{\cw{\\cfg\{paper-bottom-margin\}}}\cw{\\cfg\{paper-bottom-margin\}\{}\e{points}\cw{\}} \dd Specify the margins. Most text appears within these margins, except: \lcont{ \b Section numbers, which appear in the left margin. \b The footer (containing page numbers), which appears in the bottom margin. } \S2{output-paper-line} Vertical spacing \dt \I{\cw{\\cfg\{paper-base-leading\}}}\cw{\\cfg\{paper-base-leading\}\{}\e{points}\cw{\}} \dd Specifies the amount of space between lines of text within a paragraph. (So, if the font size is 12pt and there is 2pt of leading, there will be 14pt between successive baselines.) \dt \I{\cw{\\cfg\{paper-base-para-spacing\}}}\cw{\\cfg\{paper-base-para-spacing\}\{}\e{points}\cw{\}} \dd Specifies the amount of vertical space between paragraphs. (The vertical space between paragraphs does \e{not} include \c{paper-base-leading}.) \S2{output-paper-indentation} Indentation \dt \I{\cw{\\cfg\{paper-list-indent\}}}\cw{\\cfg\{paper-list-indent\}\{}\e{points}\cw{\}} \dd Specifies the indentation of the bullet or number in a \I{bulletted list, indentation}bulletted or \I{numbered list, indentation}numbered \I{list, indentation}list, similarly to \cw{\\cfg\{text-list-indent\}} (see \k{output-text-dimensions}). \dt \I{\cw{\\cfg\{paper-listitem-indent\}}}\cw{\\cfg\{paper-listitem-indent\}\{}\e{points}\cw{\}} \dd Specifies the \e{extra} indentation for the body of a list item, over and above the amount configured in \cw{\\cfg\{paper-list-indent\}}. \# FIXME: doesn't actually work, AFAICT. \dt \I{\cw{\\cfg\{paper-quote-indent\}}}\cw{\\cfg\{paper-quote-indent\}\{}\e{points}\cw{\}} \dd Specifies the amount of indentation for a level of quoting. Used for \cw{\\quote} (see \k{input-quote}) and code quotes with \cw{\\c} (see \k{input-code}). \S2{output-paper-headings} Headings \dt \I{\cw{\\cfg\{paper-chapter-top-space\}}}\cw{\\cfg\{paper-chapter-top-space\}\{}\e{points}\cw{\}} \dd Specifies the space between the top margin and the top of the chapter heading. (Each chapter begins on a new page.) \dt \I{\cw{\\cfg\{paper-chapter-underline-thickness\}}}\cw{\\cfg\{paper-chapter-underline-thickness\}\{}\e{points}\cw{\}} \dd Specifies the vertical thickness of the black rule under chapter headings. \dt \I{\cw{\\cfg\{paper-chapter-underline-depth\}}}\cw{\\cfg\{paper-chapter-underline-depth\}\{}\e{points}\cw{\}} \dd Specifies the distance between the base of the chapter heading and the \e{base} of the underlying rule. \dt \I{\cw{\\cfg\{paper-sect-num-left-space\}}}\cw{\\cfg\{paper-sect-num-left-space\}\{}\e{points}\cw{\}} \dd Specifies the distance between the left margin and the \e{right} of section numbers (which are in the left margin). \S2{output-paper-index} Contents and index \dt \I{\cw{\\cfg\{paper-contents-indent-step\}}}\cw{\\cfg\{paper-contents-indent-step\}\{}\e{points}\cw{\}} \dd Specifies by how much to indent each entry in the table of contents per level of subdivision in the document. (In other words, chapter titles appear at the left of the table of contents, headings within the chapter are indented by the amount configured here, subheadings by twice that, and so on.) \dt \I{\cw{\\cfg\{paper-contents-margin\}}}\cw{\\cfg\{paper-contents-margin\}\{}\e{points}\cw{\}} \dd Specifies the amount of space on the right of the table of contents which should be reserved for page numbers only. Headings in the table of contents which extend into this space will be wrapped. \dt \I{\cw{\\cfg\{paper-leader-separation\}}}\cw{\\cfg\{paper-leader-separation\}\{}\e{points}\cw{\}} \dd Specifies the horizontal spacing between dots in \i\e{leaders} (the dotted lines that appear between section headings and page numbers in the table of contents). \dt \I{\cw{\\cfg\{paper-footer-distance\}}}\cw{\\cfg\{paper-footer-distance\}\{}\e{points}\cw{\}} \dd Specifies the distance between the bottom margin and the \e{base} of the footer (which contains page numbers). \dt \I{\cw{\\cfg\{paper-index-columns\}}}\cw{\\cfg\{paper-index-columns\}\{}\e{columns}\cw{\}} \dd Specifies the number of columns the index should be divided into. \# FIXME: with this set to 1, the right-alignment of some index entry page numbers in the Halibut manual is decidedly wonky. \dt \I{\cw{\\cfg\{paper-index-gutter\}}}\cw{\\cfg\{paper-index-gutter\}\{}\e{points}\cw{\}} \dd Specifies the amount of \I{gutter} horizontal space between index columns. \dt \I{\cw{\\cfg\{paper-index-minsep\}}}\cw{\\cfg\{paper-index-minsep\}\{}\e{points}\cw{\}} \dd Specifies the minimum allowable horizontal space between an index entry and its page number. If the gap is smaller, the page number is moved to the next line. \S2{output-paper-fonts} \ii{Fonts} The directives in this section control which fonts Halibut uses for various kinds of text. Directives for setting the font normally take three font names, the first of which is used for normal text, the second for emphasised text, and the third for code. Any fonts which aren't specified are left unchanged. Halibut intrinsically knows about some fonts, and these fonts are also built into all PDF and most PostScript implementations. These fonts can be used without further formality. Halibut can also use other fonts, and can \I{embedding fonts}embed them it its PDF and PostScript output. These other fonts are supplied to Halibut by simply adding them to the list of input files on its command line. To use a \i{Type 1 font} Halibut needs both the font file itself, in either hexadecimal (\I{PFA files}PFA) or IBM PC (\I{PFB files}PFB) format, and an \i{Adobe Font Metrics} (\I{AFM files}AFM) file. The AFM file must be specified first on the command line. If Halibut gets an AFM file without a corresponding Type 1 font file, the PostScript and PDF output files will still use that font, but they won't contain it. Using a \i{TrueType font} is rather simpler, and simply requires you to pass the font file to Halibut. Halibut does place a few restrictions on TrueType fonts, notably that they must include a \i{Unicode} mapping table and a PostScript name. Fonts are specified using their PostScript names. Running Halibut with the \i\cw{\-\-list-fonts} option causes it to display the PostScript names of all the fonts it intrinsically knows about, along with any fonts the were supplied as input files. \ii{Font sizes} are specified in PostScript \i{points} (72 to the inch). \dt \I{\cw{\\cfg\{paper-title-fonts\}}}\cw{\\cfg\{paper-title-fonts\}\{}\e{normal-font}\cw{\}}[\cw{\{}\e{emph-font}\cw{\}}[\cw{\{}\e{code-font}\cw{\}}]] \dd Specifies the fonts to use for text in the document title. \dt \I{\cw{\\cfg\{paper-title-font-size\}}}\cw{\\cfg\{paper-title-font-size\}\{}\e{points}\cw{\}} \dd Specifies the \i{font size} of the document title. \dt \I{\cw{\\cfg\{paper-chapter-fonts\}}}\cw{\\cfg\{paper-chapter-fonts\}\{}\e{normal-font}\cw{\}}[\cw{\{}\e{emph-font}\cw{\}}[\cw{\{}\e{code-font}\cw{\}}]] \dd Specifies the fonts to use for text in chapter titles. \dt \I{\cw{\\cfg\{paper-chapter-font-size\}}}\cw{\\cfg\{paper-chapter-font-size\}\{}\e{points}\cw{\}} \dd Specifies the \i{font size} of chapter titles. \dt \I{\cw{\\cfg\{paper-section-fonts\}}}\cw{\\cfg\{paper-section-fonts\}\{}\e{level}\cw{\}\{}\e{normal-font}\cw{\}}[\cw{\{}\e{emph-font}\cw{\}}[\cw{\{}\e{code-font}\cw{\}}]] \dd Specifies the fonts to use for text in section headings at the \e{level} specified. \dt \I{\cw{\\cfg\{paper-section-font-size\}}}\cw{\\cfg\{paper-section-font-size\}\{}\e{level}\cw{\}\{}\e{points}\cw{\}} \dd Specifies the \i{font size} of section headings at the \e{level} specified. \dt \I{\cw{\\cfg\{paper-base-fonts\}}}\cw{\\cfg\{paper-base-fonts\}\{}\e{normal-font}\cw{\}}[\cw{\{}\e{emph-font}\cw{\}}[\cw{\{}\e{code-font}\cw{\}}]] \dd Specifies the fonts to use for text in the body text. \dt \I{\cw{\\cfg\{paper-base-font-size\}}}\cw{\\cfg\{paper-base-font-size\}\{}\e{points}\cw{\}} \dd Specifies the \i{font size} of body text. \dt \I{\cw{\\cfg\{paper-code-fonts\}}}\cw{\\cfg\{paper-code-fonts\}\{}\e{bold-font}\cw{\}}[\cw{\{}\e{italic-font}\cw{\}}[\cw{\{}\e{normal-font}\cw{\}}]] \dd Specifies the fonts to use for text in code paragraphs. The \e{bold-font} is used for bold text, the \e{italic-font} for emphasised text, and the \e{normal-font} for normal code. \dt \I{\cw{\\cfg\{paper-code-font-size\}}}\cw{\\cfg\{paper-code-font-size\}\{}\e{points}\cw{\}} \dd Specifies the \i{font size} of text in code paragraphs. \dt \I{\cw{\\cfg\{paper-pagenum-font-size\}}}\cw{\\cfg\{paper-pagenum-font-size\}\{}\e{points}\cw{\}} \dd Specifies the font size to use for \i{page numbers}. \S2{output-paper-misc} Miscellaneous \dt \I{\cw{\\cfg\{paper-rule-thickness\}}}\cw{\\cfg\{paper-rule-thickness\}\{}\e{points}\cw{\}} \dd Specifies the vertical thickness of the rule produced by the \cw{\\rule} command (see \k{input-rule}).
