mchars_alloc 3 +and +.Fn mparse_alloc ; +.It +open a file with +.Xr open 2 +or +.Fn mparse_open ; +.It +parse it with +.Fn mparse_readfd ; +.It +close it with +.Xr close 2 ; +.It +retrieve the syntax tree with +.Fn mparse_result ; +.It +depending on whether the +.Fa macroset +member of the returned +.Vt struct roff_man +is +.Dv MACROSET_MDOC +or +.Dv MACROSET_MAN , +validate it with +.Fn mdoc_validate +or +.Fn man_validate , +respectively; +.It +iterate over parse nodes with starting from the +.Fa first +member of the returned +.Vt struct roff_man ; +.It +free all allocated memory with +.Fn mparse_free +and +.Xr mchars_free 3 , +or invoke +.Fn mparse_reset +and go back to step 2 to parse new files. +.El +.Sh REFERENCE +This section documents the functions, types, and variables available +via +.In mandoc.h , +with the exception of those documented in +.Xr mandoc_escape 3 +and +.Xr mchars_alloc 3 . +.Ss Types +.Bl -ohang +.It Vt "enum mandocerr" +An error or warning message during parsing. +.It Vt "enum mandoclevel" +A classification of an +.Vt "enum mandocerr" +as regards system operation. +See the DIAGNOSTICS section in +.Xr mandoc 1 +regarding the meanings of the levels. +.It Vt "struct mparse" +An opaque pointer to a running parse sequence. +Created with +.Fn mparse_alloc +and freed with +.Fn mparse_free . +This may be used across parsed input if +.Fn mparse_reset +is called between parses. +.It Vt "mandocmsg" +A prototype for a function to handle error and warning +messages emitted by the parser. +.El +.Ss Functions +.Bl -ohang +.It Fn deroff +Obtain a text-only representation of a +.Vt struct roff_node , +including text contained in its child nodes. +To be used on children of the +.Fa first +member of +.Vt struct roff_man . +When it is no longer needed, the pointer returned from +.Fn deroff +can be passed to +.Xr free 3 . +.It Fn man_mparse +Get the parser used for the current output. +Declared in +.In man.h , +implemented in +.Pa man.c . +.It Fn man_validate +Validate the +.Dv MACROSET_MAN +parse tree obtained with +.Fn mparse_result . +Declared in +.In man.h , +implemented in +.Pa man.c . +.It Fn mdoc_validate +Validate the +.Dv MACROSET_MDOC +parse tree obtained with +.Fn mparse_result . +Declared in +.In mdoc.h , +implemented in +.Pa mdoc.c . +.It Fn mparse_alloc +Allocate a parser. +The arguments have the following effect: +.Bl -tag -offset 5n -width inttype +.It Ar options +When the +.Dv MPARSE_MDOC +or +.Dv MPARSE_MAN +bit is set, only that parser is used. +Otherwise, the document type is automatically detected. +.Pp +When the +.Dv MPARSE_SO +bit is set, +.Xr roff 7 +.Ic \&so +file inclusion requests are always honoured. +Otherwise, if the request is the only content in an input file, +only the file name is remembered, to be returned in the +.Fa sodest +argument of +.Fn mparse_result . +.Pp +When the +.Dv MPARSE_QUICK +bit is set, parsing is aborted after the NAME section. +This is for example useful in +.Xr makewhatis 8 +.Fl Q +to quickly build minimal databases. +.It Ar wlevel +Can be set to +.Dv MANDOCLEVEL_BADARG , +.Dv MANDOCLEVEL_ERROR , +or +.Dv MANDOCLEVEL_WARNING . +Messages below the selected level will be suppressed. +.It Ar mmsg +A callback function to handle errors and warnings. +See +.Pa main.c +for an example. +If printing of error messages is not desired, +.Dv NULL +may be passed. +.It Ar defos +A default string for the +.Xr mdoc 7 +.Sq \&Os +macro, overriding the +.Dv OSNAME +preprocessor definition and the results of +.Xr uname 3 . +Passing +.Dv NULL +sets no default. +.El +.Pp +The same parser may be used for multiple files so long as +.Fn mparse_reset +is called between parses. +.Fn mparse_free +must be called to free the memory allocated by this function. +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_free +Free all memory allocated by +.Fn mparse_alloc . +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_getkeep +Acquire the keep buffer. +Must follow a call of +.Fn mparse_keep . +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_keep +Instruct the parser to retain a copy of its parsed input. +This can be acquired with subsequent +.Fn mparse_getkeep +calls. +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_open +Open the file for reading. +If that fails and +.Fa fname +does not already end in +.Ql .gz , +try again after appending +.Ql .gz . +Save the information whether the file is zipped or not. +Return a file descriptor open for reading or -1 on failure. +It can be passed to +.Fn mparse_readfd +or used directly. +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_readfd +Parse a file descriptor opened with +.Xr open 2 +or +.Fn mparse_open . +Pass the associated filename in +.Va fname . +This function may be called multiple times with different parameters; however, +.Xr close 2 +and +.Fn mparse_reset +should be invoked between parses. +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_reset +Reset a parser so that +.Fn mparse_readfd +may be used again. +Declared in +.In mandoc.h , +implemented in +.Pa read.c . +.It Fn mparse_result +Obtain the result of a parse. +One of the two pointers will be filled in. +Declared in +.In mandoc.h , +implemented in +.Pa

of a +.Xr man 7 +macro as indexed by +.Vt "enum mant" . +.It Va mdoc_argnames +The string representation of an +.Xr mdoc 7 +macro argument as indexed by +.Vt "enum mdocargt" . +.It Va mdoc_macronames +The string representation of an +.Xr mdoc 7 +macro as indexed by +.Vt "enum mdoct" . +.El +.Sh IMPLEMENTATION NOTES +This section consists of structural documentation for +.Xr mdoc 7 +and +.Xr man 7 +syntax trees and strings. +.Ss Man and Mdoc Strings +Strings may be extracted from mdoc and man meta-data, or from text +nodes (MDOC_TEXT and MAN_TEXT, respectively). +These strings have special non-printing formatting cues embedded in the +text itself, as well as +.Xr roff 7 +escapes preserved from input. +Implementing systems will need to handle both situations to produce +human-readable text. +In general, strings may be assumed to consist of 7-bit ASCII characters. +.Pp +The following non-printing characters may be embedded in text strings: +.Bl -tag -width Ds +.It Dv ASCII_NBRSP +A non-breaking space character. +.It Dv ASCII_HYPH +A soft hyphen. +.It Dv ASCII_BREAK +A breakable zero-width space. +.El +.Pp +Escape characters are also passed verbatim into text strings. +An escape character is a sequence of characters beginning with the +backslash +.Pq Sq \e . +To construct human-readable text, these should be intercepted with +.Xr mandoc_escape 3 +and converted with one the functions described in +.Xr mchars_alloc 3 . +.Ss Man Abstract Syntax Tree +This AST is governed by the ontological rules dictated in +.Xr man 7 +and derives its terminology accordingly. +.Pp +The AST is composed of +.Vt struct roff_node +nodes with element, root and text types as declared by the +.Va type +field. +Each node also provides its parse point (the +.Va line , +.Va pos , +and +.Va sec +fields), its position in the tree (the +.Va parent , +.Va child , +.Va next +and +.Va prev +fields) and some type-specific data. +.Pp +The tree itself is arranged according to the following normal form, +where capitalised non-terminals represent nodes. +.Pp +.Bl -tag -width "ELEMENTXX" -compact +.It ROOT +\(<- mnode+ +.It mnode +\(<- ELEMENT | TEXT | BLOCK +.It BLOCK +\(<- HEAD BODY +.It HEAD +\(<- mnode* +.It BODY +\(<- mnode* +.It ELEMENT +\(<- ELEMENT | TEXT* +.It TEXT +\(<- [[:ascii:]]* +.El +.Pp +The only elements capable of nesting other elements are those with +next-line scope as documented in +.Xr man 7 . +.Ss Mdoc Abstract Syntax Tree +This AST is governed by the ontological +rules dictated in +.Xr mdoc 7 +and derives its terminology accordingly. +.Qq In-line +elements described in +.Xr mdoc 7 +are described simply as +.Qq elements . +.Pp +The AST is composed of +.Vt struct roff_node +nodes with block, head, body, element, root and text types as declared +by the +.Va type +field. +Each node also provides its parse point (the +.Va line , +.Va pos , +and +.Va sec +fields), its position in the tree (the +.Va parent , +.Va child , +.Va last , +.Va next +and +.Va prev +fields) and some type-specific data, in particular, for nodes generated +from macros, the generating macro in the +.Va tok +field. +.Pp +The tree itself is arranged according to the following normal form, +where capitalised non-terminals represent nodes. +.Pp +.Bl -tag -width "ELEMENTXX" -compact +.It ROOT +\(<- mnode+ +.It mnode +\(<- BLOCK | ELEMENT | TEXT +.It BLOCK +\(<- HEAD [TEXT] (BODY [TEXT])+ [TAIL [TEXT]] +.It ELEMENT +\(<- TEXT* +.It HEAD +\(<- mnode* +.It BODY +\(<- mnode* [ENDBODY mnode*] +.It TAIL +\(<- mnode* +.It TEXT +\(<- [[:ascii:]]* +.El +.Pp +Of note are the TEXT nodes following the HEAD, BODY and TAIL nodes of +the BLOCK production: these refer to punctuation marks. +Furthermore, although a TEXT node will generally have a non-zero-length +string, in the specific case of +.Sq \&.Bd \-literal , +an empty line will produce a zero-length string. +Multiple body parts are only found in invocations of +.Sq \&Bl \-column , +where a new body introduces a new phrase. +.Pp +The +.Xr mdoc 7 +syntax tree accommodates for broken block structures as well. +The ENDBODY node is available to end the formatting associated +with a given block before the physical end of that block. +It has a non-null +.Va end +field, is of the BODY +.Va type , +has the same +.Va tok +as the BLOCK it is ending, and has a +.Va pending +field pointing to that BLOCK's BODY node. +It is an indirect child of that BODY node +and has no children of its own. +.Pp +An ENDBODY node is generated when a block ends while one of its child +blocks is still open, like in the following example: +.Bd -literal -offset indent +\&.Ao ao +\&.Bo bo ac +\&.Ac bc +\&.Bc end +.Ed +.Pp +This example results in the following block structure: +.Bd -literal -offset indent +BLOCK Ao + HEAD Ao + BODY Ao + TEXT ao + BLOCK Bo, pending -> Ao + HEAD Bo + BODY Bo + TEXT bo + TEXT ac + ENDBODY Ao, pending -> Ao + TEXT bc +TEXT end +.Ed +.Pp +Here, the formatting of the +.Sq \&Ao +block extends from TEXT ao to TEXT ac, +while the formatting of the +.Sq \&Bo +block extends from TEXT bo to TEXT bc. +It renders as follows in +.Fl T Ns Cm ascii +mode: +.Pp +.Dl <ao [bo ac> bc] end +.Pp +Support for badly-nested blocks is only provided for backward +compatibility with some older +.Xr mdoc 7 +implementations. +Using badly-nested blocks is +.Em strongly discouraged ; +for example, the +.Fl T Ns Cm html +and +.Fl T Ns Cm xhtml +front-ends to +.Xr mandoc 1 +are unable to render them in any meaningful way. +Furthermore, behaviour when encountering badly-nested blocks is not +consistent across troff implementations, especially when using multiple +levels of badly-nested blocks. +.Sh SEE ALSO +.Xr mandoc 1 , +.Xr man.cgi 3 , +.Xr mandoc_escape 3 , +.Xr mandoc_headers 3 , +.Xr mandoc_malloc 3

names into glyphs. +See +.Xr mandoc_char 7 +for a list of +.Xr roff 7 +special characters. +These functions are intended for external use by programs formatting +.Xr mdoc 7 +and +.Xr man 7 +pages for output, for example the +.Xr mandoc 1 +output formatter modules and +.Xr makewhatis 8 . +The +.Fa decimal , +.Fa hexadecimal , +.Fa name , +and +.Fa size +input arguments are usually obtained from the +.Xr mandoc_escape 3 +parser function. +.Pp +The function +.Fn mchars_num2char +converts a +.Fa decimal +string representation of a character number consisting of +.Fa sz +digits into a printable ASCII character. +If the input string is non-numeric or does not represent a printable +ASCII character, the NUL character +.Pq Sq \e0 +is returned. +For example, the +.Xr mandoc 1 +.Fl Tascii , +.Fl Tutf8 , +and +.Fl Thtml +output modules use this function to render +.Xr roff 7 +.Ic \eN +escape sequences. +.Pp +The function +.Fn mchars_num2uc +converts a +.Fa hexadecimal +string representation of a Unicode codepoint consisting of +.Fa sz +digits into an integer representation. +If the input string is non-numeric or represents an ASCII character, +the NUL character +.Pq Sq \e0 +is returned. +For example, the +.Xr mandoc 1 +.Fl Tutf8 +and +.Fl Thtml +output modules use this function to render +.Xr roff 7 +.Ic \e[u Ns Ar XXXX Ns Ic \&] +and +.Ic \eC\(aqu Ns Ar XXXX Ns Ic \(aq +escape sequences. +.Pp +The function +.Fn mchars_alloc +initializes a static +.Vt "struct ohash" +object for subsequent use by the following two lookup functions. +When no longer needed, this object can be destroyed with +.Fn mchars_free . +.Pp +The function +.Fn mchars_spec2cp +looks up a +.Xr roff 7 +special character +.Fa name +consisting of +.Fa sz +characters and returns the corresponding Unicode codepoint. +If the +.Ar name +is not recognized, \-1 is returned. +For example, the +.Xr mandoc 1 +.Fl Tutf8 +and +.Fl Thtml +output modules use this function to render +.Xr roff 7 +.Ic \e[ Ns Ar name Ns Ic \&] +and +.Ic \eC\(aq Ns Ar name Ns Ic \(aq +escape sequences. +.Pp +The function +.Fn mchars_spec2str +looks up a +.Xr roff 7 +special character +.Fa name +consisting of +.Fa sz +characters and returns an ASCII string representation. +The length of the representation is returned in +.Fa rsz . +In many cases, the meaning of such ASCII representations +is not quite obvious, so using +.Xr roff 7 +special characters in documents intended for ASCII rendering +is usually a bad idea. +If the +.Ar name +is not recognized, +.Dv NULL +is returned. +For example, +.Xr makewhatis 8 +and the +.Xr mandoc 1 +.Fl Tascii +output module use this function to render +.Xr roff 7 +.Ic \e[ Ns Ar name Ns Ic \&] +and +.Ic \eC\(aq Ns Ar name Ns Ic \(aq +escape sequences. +.Pp +The function +.Fn

in ASCII output, most characters are completely +unintelligible. +For that reason, using any of the special characters documented here, +except those discussed in the +.Sx DESCRIPTION , +is strongly discouraged; they are supported merely for backwards +compatibility with existing documents. +.Pp +In particular, in English manual pages, do not use special-character +escape sequences to represent national language characters in author +names; instead, provide ASCII transcriptions of the names. +.Ss Dashes and Hyphens +In typography there are different types of dashes of various width: +the hyphen (-), +the minus sign (\(mi), +the en-dash (\(en), +and the em-dash (\(em). +.Pp +Hyphens are used for adjectives; +to separate the two parts of a compound word; +or to separate a word across two successive lines of text. +The hyphen does not need to be escaped: +.Bd -unfilled -offset indent +blue-eyed +lorry-driver +.Ed +.Pp +The mathematical minus sign is used for negative numbers or subtraction. +It should be written as +.Sq \e(mi : +.Bd -unfilled -offset indent +a = 3 \e(mi 1; +b = \e(mi2; +.Ed +.Pp +The en-dash is used to separate the two elements of a range, +or can be used the same way as an em-dash. +It should be written as +.Sq \e(en : +.Bd -unfilled -offset indent +pp. 95\e(en97. +Go away \e(en or else! +.Ed +.Pp +The em-dash can be used to show an interruption +or can be used the same way as colons, semi-colons, or parentheses. +It should be written as +.Sq \e(em : +.Bd -unfilled -offset indent +Three things \e(em apples, oranges, and bananas. +This is not that \e(em rather, this is that. +.Ed +.Pp +Note: +hyphens, minus signs, and en-dashes look identical under normal ASCII output. +Other formats, such as PostScript, render them correctly, +with differing widths. +.Ss Spaces +To separate words in normal text, for indenting and alignment +in literal context, and when none of the following special cases apply, +just use the normal space character +.Pq Sq \ . +.Pp +When filling text, output lines may be broken between words, i.e. at space +characters. +To prevent a line break between two particular words, +use the unpaddable non-breaking space escape sequence +.Pq Sq \e\ \& +instead of the normal space character. +For example, the input string +.Dq number\e\ 1 +will be kept together as +.Dq number\ 1 +on the same output line. +.Pp +On request and macro lines, the normal space character serves as an +argument delimiter. +To include whitespace into arguments, quoting is usually the best choice; +see the MACRO SYNTAX section in +.Xr roff 7 . +In some cases, using the non-breaking space escape sequence +.Pq Sq \e\ \& +may be preferable. +.Pp +To escape macro names and to protect whitespace at the end +of input lines, the zero-width space +.Pq Sq \e& +is often useful. +For example, in +.Xr mdoc 7 , +a normal space character can be displayed in single quotes in either +of the following ways: +.Pp +.Dl .Sq \(dq \(dq +.Dl .Sq \e \e& +.Ss Quotes +On request and macro lines, the double-quote character +.Pq Sq \(dq +is handled specially to allow quoting. +One way to prevent this special handling is by using the +.Sq \e(dq +escape sequence. +.Pp +Note that on text lines, literal double-quote characters can be used +verbatim. +All other quote-like characters can be used verbatim as well, +even on request and macro lines. +.Ss Accents +In output modes supporting such special output characters, for example +.Fl T Cm pdf , +some +.Xr roff 7 +formatters convert the following ASCII input characters to the +following Unicode special output characters: +.Bl -column x(ga U+2018 -offset indent +.It \(ga Ta U+2018 Ta left single quotation mark +.It \(aq Ta U+2019 Ta right single quotation mark +.It \(ti Ta U+02DC Ta small tilde +.El +.Pp +In prose, this automatic substitution is often desirable; +but when these characters have to be displayed as plain ASCII +characters, for example in source code samples, they require +escaping to render as follows: +.Bl -column x(ga U+2018 -offset indent +.It \e(ga Ta U+0060 Ta grave accent +.It \e(aq Ta U+0027 Ta apostrophe +.It \e(ti Ta U+007E Ta tilde +.El +.Ss Periods +The period +.Pq Sq \&. +is handled specially at the beginning of an input line, +where it introduces a +.Xr roff 7 +request or a macro, and when appearing alone as a macro argument in +.Xr mdoc 7 . +In such situations, prepend a zero-width space +.Pq Sq \e&. +to make it behave like normal text. +.Pp +Do not use the +.Sq \e. +escape sequence. +It does not prevent special handling of the period. +.Ss Backslashes +To include a literal backslash +.Pq Sq \e +into the output, use the +.Pq Sq \ee +escape sequence. +.Pp +Note that doubling it +.Pq Sq \e\e +is not the right way to output a backslash. +Because +.Xr mandoc 1 +does not implement full +.Xr roff 7 +functionality, it may work with +.Xr mandoc 1 , +but it may have weird effects on complete +.Xr roff 7 +implementations. +.Sh SPECIAL CHARACTERS +Special characters are encoded as +.Sq \eX +.Pq for a one-character escape , +.Sq \e(XX +.Pq two-character , +and +.Sq \e[N] +.Pq N-character . +For details, see the +.Em Special Characters +subsection of the +.Xr roff 7 +manual. +.Pp +Spacing: +.Bl -column "Input" "Description" -offset indent -compact +.It Em Input Ta Em Description +.It Sq \e\ \& Ta unpaddable non-breaking space +.It \e\(ti Ta paddable non-breaking space +.It \e0 Ta unpaddable, breaking digit-width space +.It \e| Ta one-sixth \e(em narrow space, zero width in nroff mode +.It \e^ Ta one-twelfth \e(em half-narrow space, zero width in nroff +.It \e& Ta zero-width space +.It \e% Ta zero-width space allowing hyphenation +.El +.Pp +Lines: +.Bl -column "Input" "Rendered" "Description" -offset indent -compact +.It Em Input Ta Em Rendered Ta Em Description +.It \e(ba Ta \(ba Ta bar +.It \e(br Ta \(br Ta box rule +.It \e(ul Ta \(ul Ta underscore +.It \e(rn Ta \(rn Ta overline +.It \e(bb Ta \(bb Ta broken bar +.It \e(sl Ta \(sl Ta forward slash +.It \e(rs Ta \(rs Ta backward slash +.El +.Pp +Text markers: +.Bl -column "Input" "Rendered" "Description" -offset indent -compact +.It Em Input Ta Em Rendered Ta Em Description +.It \e(ci Ta \(ci Ta circle +.It \e(bu Ta \(bu Ta bullet +.It \e(dd Ta \(dd Ta double dagger +.It \e(dg Ta \(dg Ta dagger +.It \e(lz Ta \(lz Ta lozenge +.It \e(sq Ta \(sq Ta white square +.It \e(ps Ta \(ps Ta paragraph +.It \e(sc Ta \(sc Ta section +.It \e(lh Ta \(lh Ta left hand +.It \e(rh Ta \(rh Ta right hand +.It \e(at Ta \(at Ta at +.It \e(sh Ta \(sh Ta hash (pound) +.It \e(CR Ta \(CR Ta carriage return +.It \e(OK Ta \(OK Ta check mark +.El +.Pp +Legal symbols: +.Bl -column "Input" "Rendered" "Description" -offset indent -compact +.It Em Input Ta Em Rendered Ta Em Description +.It \e(co Ta \(co Ta copyright +.It \e(rg Ta \(rg Ta registered +.It \e(tm Ta \(tm Ta trademarked +.El +.Pp +Punctuation: +.Bl -column "Input" "Rendered" "Description" -offset indent -compact +.It Em Input Ta Em Rendered Ta Em Description +.It \e(em Ta \(em Ta em-dash +.It \e(en Ta \(en Ta en-dash +.It \e(hy Ta \(hy Ta hyphen +.It \ee Ta \e Ta back-slash +.It \e.

\e[uXXXX] and \eC\(aquXXXX\(aq +.Pp +are interpreted as Unicode codepoints. +The codepoint must be in the range above U+0080 and less than U+10FFFF. +For compatibility, the hexadecimal digits +.Sq A +to +.Sq F +must be given as uppercase characters, +and points must be zero-padded to four characters; if +greater than four characters, no zero padding is allowed. +Unicode surrogates are not allowed. +.Sh NUMBERED CHARACTERS +For backward compatibility with existing manuals, +.Xr mandoc 1 +also supports the +.Pp +.Dl \eN\(aq Ns Ar number Ns \(aq +.Pp +escape sequence, inserting the character +.Ar number +from the current character set into the output. +Of course, this is inherently non-portable and is already marked +as deprecated in the Heirloom roff manual. +For example, do not use \eN\(aq34\(aq, use \e(dq, or even the plain +.Sq \(dq +character where possible. +.Sh COMPATIBILITY +This section documents compatibility between mandoc and other +troff implementations, at this time limited to GNU troff +.Pq Qq groff . +.Pp +.Bl -dash -compact +.It +The \eN\(aq\(aq escape sequence is limited to printable characters; in +groff, it accepts arbitrary character numbers.

NAME +.Nm mdoc +.Nd semantic markup language for formatting manual pages +.Sh DESCRIPTION +The +.Nm mdoc +language supports authoring of manual pages for the +.Xr man 1 +utility by allowing semantic annotations of words, phrases, +page sections and complete manual pages. +Such annotations are used by formatting tools to achieve a uniform +presentation across all manuals written in +.Nm , +and to support hyperlinking if supported by the output medium. +.Pp +This reference document describes the structure of manual pages +and the syntax and usage of the +.Nm +language. +The reference implementation of a parsing and formatting tool is +.Xr mandoc 1 ; +the +.Sx COMPATIBILITY +section describes compatibility with other implementations. +.Pp +In an +.Nm +document, lines beginning with the control character +.Sq \&. +are called +.Dq macro lines . +The first word is the macro name. +It consists of two or three letters. +Most macro names begin with a capital letter. +For a list of available macros, see +.Sx MACRO OVERVIEW . +The words following the macro name are arguments to the macro, optionally +including the names of other, callable macros; see +.Sx MACRO SYNTAX +for details. +.Pp +Lines not beginning with the control character are called +.Dq text lines . +They provide free-form text to be printed; the formatting of the text +depends on the respective processing context: +.Bd -literal -offset indent +\&.Sh Macro lines change control state. +Text lines are interpreted within the current state. +.Ed +.Pp +Many aspects of the basic syntax of the +.Nm +language are based on the +.Xr roff 7 +language; see the +.Em LANGUAGE SYNTAX +and +.Em MACRO SYNTAX +sections in the +.Xr roff 7 +manual for details, in particular regarding +comments, escape sequences, whitespace, and quoting. +However, using +.Xr roff 7 +requests in +.Nm +documents is discouraged; +.Xr mandoc 1 +supports some of them merely for backward compatibility. +.Sh MANUAL STRUCTURE +A well-formed +.Nm +document consists of a document prologue followed by one or more +sections. +.Pp +The prologue, which consists of the +.Sx \&Dd , +.Sx \&Dt , +and +.Sx \&Os +macros in that order, is required for every document. +.Pp +The first section (sections are denoted by +.Sx \&Sh ) +must be the NAME section, consisting of at least one +.Sx \&Nm +followed by +.Sx \&Nd . +.Pp +Following that, convention dictates specifying at least the +.Em SYNOPSIS +and +.Em DESCRIPTION +sections, although this varies between manual sections. +.Pp +The following is a well-formed skeleton +.Nm +file for a

+Multiple +.Sq \&Nm +names should be separated by commas. +.Pp +The +.Sx \&Nm +macro(s) must precede the +.Sx \&Nd +macro. +.Pp +See +.Sx \&Nm +and +.Sx \&Nd . +.It Em LIBRARY +The name of the library containing the documented material, which is +assumed to be a function in a section 2, 3, or 9 manual. +The syntax for this is as follows: +.Bd -literal -offset indent +\&.Lb libarm +.Ed +.Pp +See +.Sx \&Lb . +.It Em SYNOPSIS +Documents the utility invocation syntax, function call syntax, or device +configuration. +.Pp +For the first, utilities (sections 1, 6, and 8), this is +generally structured as follows: +.Bd -literal -offset indent +\&.Nm bar +\&.Op Fl v +\&.Op Fl o Ar file +\&.Op Ar +\&.Nm foo +\&.Op Fl v +\&.Op Fl o Ar file +\&.Op Ar +.Ed +.Pp +Commands should be ordered alphabetically. +.Pp +For the second, function calls (sections 2, 3, 9): +.Bd -literal -offset indent +\&.In header.h +\&.Vt extern const char *global; +\&.Ft "char *" +\&.Fn foo "const char *src" +\&.Ft "char *" +\&.Fn bar "const char *src" +.Ed +.Pp +Ordering of +.Sx \&In , +.Sx \&Vt , +.Sx \&Fn , +and +.Sx \&Fo +macros should follow C header-file conventions. +.Pp +And for the third, configurations (section 4): +.Bd -literal -offset indent +\&.Cd \(dqit* at isa? port 0x2e\(dq +\&.Cd \(dqit* at isa? port 0x4e\(dq +.Ed +.Pp +Manuals not in these sections generally don't need a +.Em SYNOPSIS . +.Pp +Some macros are displayed differently in the +.Em SYNOPSIS +section, particularly +.Sx \&Nm , +.Sx \&Cd , +.Sx \&Fd , +.Sx \&Fn , +.Sx \&Fo , +.Sx \&In , +.Sx \&Vt , +and +.Sx \&Ft . +All of these macros are output on their own line. +If two such dissimilar macros are pairwise invoked (except for +.Sx \&Ft +before +.Sx \&Fo +or +.Sx \&Fn ) , +they are separated by a vertical space, unless in the case of +.Sx \&Fo , +.Sx \&Fn , +and +.Sx \&Ft , +which are always separated by vertical space. +.Pp +When text and macros following an +.Sx \&Nm +macro starting an input line span multiple output lines, +all output lines but the first will be indented to align +with the text immediately following the +.Sx \&Nm +macro, up to the next +.Sx \&Nm , +.Sx \&Sh , +or +.Sx \&Ss +macro or the end of an enclosing block, whichever comes first. +.It Em DESCRIPTION +This begins with an expansion of the brief, one line description in +.Em NAME : +.Bd -literal -offset indent +The +\&.Nm +utility does this, that, and the other. +.Ed +.Pp +It usually follows with a breakdown of the options (if documenting a +command), such as: +.Bd -literal -offset indent +The arguments are as follows: +\&.Bl \-tag \-width Ds +\&.It Fl v +Print verbose information. +\&.El +.Ed +.Pp +List the options in alphabetical order, +uppercase before lowercase for each letter and +with no regard to whether an option takes an argument. +Put digits in ascending order before all letter options. +.Pp +Manuals not documenting a command won't include the above fragment. +.Pp +Since the +.Em DESCRIPTION +section usually contains most of the text of a manual, longer manuals +often use the +.Sx \&Ss +macro to form subsections. +In very long manuals, the +.Em DESCRIPTION +may be split into multiple sections, each started by an +.Sx \&Sh +macro followed by a non-standard section name, and each having +several subsections, like in the present +.Nm +manual. +.It Em CONTEXT +This section lists the contexts in which functions can be called in section 9. +The contexts are autoconf, process, or interrupt. +.It Em IMPLEMENTATION NOTES +Implementation-specific notes should be kept here. +This is useful when implementing standard functions that may have side +effects or notable algorithmic implications. +.It Em RETURN VALUES +This section documents the +return values of functions in sections 2, 3, and 9. +.Pp +See +.Sx \&Rv . +.It Em ENVIRONMENT +Lists the environment variables used by the utility, +and explains the syntax and semantics of their values. +The +.Xr environ 7 +manual provides examples of typical content and formatting. +.Pp +See +.Sx \&Ev . +.It Em FILES +Documents files used. +It's helpful to document both the file name and a short description of how +the file is used (created, modified, etc.). +.Pp +See +.Sx \&Pa . +.It Em EXIT STATUS +This section documents the +command exit status for section 1, 6, and 8 utilities. +Historically, this information was described in +.Em DIAGNOSTICS , +a practise that is now discouraged. +.Pp +See +.Sx \&Ex . +.It Em EXAMPLES +Example usages. +This often contains snippets of well-formed, well-tested invocations. +Make sure that examples work properly! +.It Em DIAGNOSTICS +Documents error messages. +In section 4 and 9 manuals, these are usually messages printed by the +kernel to the console and to the kernel log. +In section 1, 6, 7, and 8, these are usually messages printed by +userland programs to the standard error output. +.Pp +Historically, this section was used in place of +.Em EXIT STATUS +for manuals in sections 1, 6, and 8; however, this practise is +discouraged. +.Pp +See +.Sx \&Bl +.Fl diag . +.It Em ERRORS +Documents +.Xr errno 2 +settings in sections 2, 3, 4, and 9. +.Pp +See +.Sx \&Er . +.It Em SEE ALSO +References other manuals with related topics. +This section should exist for most manuals. +Cross-references should conventionally be ordered first by section, then +alphabetically (ignoring case). +.Pp +References to other documentation concerning the topic of the manual page, +for example authoritative books or journal articles, may also be +provided in this section. +.Pp +See +.Sx \&Rs +and +.Sx \&Xr . +.It Em STANDARDS +References any standards implemented or used. +If not adhering to any standards, the +.Em HISTORY +section should be used instead. +.Pp

use +.Sq \e&. +to prevent that. +.Pp +Many in-line macros interrupt their scope when they encounter +delimiters, and resume their scope when more arguments follow that +are not delimiters. +For example, +.Pp +.D1 Pf \. \&Fl "a ( b | c \e*(Ba d ) e" +.Pp +renders as: +.Pp +.D1 Fl a ( b | c \*(Ba d ) e +.Pp +This applies to both opening and closing delimiters, +and also to the middle delimiter: +.Pp +.Bl -tag -width Ds -offset indent -compact +.It \&| +vertical bar +.El +.Pp +As a special case, the predefined string \e*(Ba is handled and rendered +in the same way as a plain +.Sq \&| +character. +Using this predefined string is not recommended in new manuals. +.Ss Font handling +In +.Nm +documents, usage of semantic markup is recommended in order to have +proper fonts automatically selected; only when no fitting semantic markup +is available, consider falling back to +.Sx Physical markup +macros. +Whenever any +.Nm +macro switches the +.Xr roff 7 +font mode, it will automatically restore the previous font when exiting +its scope. +Manually switching the font using the +.Xr roff 7 +.Ql \ef +font escape sequences is never required. +.Sh COMPATIBILITY +This section provides an incomplete list of compatibility issues +between mandoc and GNU troff +.Pq Qq groff . +.Pp +The following problematic behaviour is found in groff: +.Pp +.Bl -dash -compact +.It +.Sx \&Dd +with non-standard arguments behaves very strangely. +When there are three arguments, they are printed verbatim. +Any other number of arguments is replaced by the current date, +but without any arguments the string +.Dq Epoch +is printed. +.It +.Sx \&Lk +only accepts a single link-name argument;

the formatting of the text +depends on the respective processing context. +.Sh LANGUAGE SYNTAX +.Nm +documents may contain only graphable 7-bit ASCII characters, the space +character, and, in certain circumstances, the tab character. +The backslash character +.Sq \e +indicates the start of an escape sequence, used for example for +.Sx Comments , +.Sx Special Characters , +.Sx Predefined Strings , +and +user-defined strings defined using the +.Sx ds +request. +For a listing of escape sequences, consult the +.Sx ESCAPE SEQUENCE REFERENCE +below. +.Ss Comments +Text following an escaped double-quote +.Sq \e\(dq , +whether in a request, macro, or text line, is ignored to the end of the line. +A request line beginning with a control character and comment escape +.Sq \&.\e\(dq +is also ignored. +Furthermore, request lines with only a control character and optional +trailing whitespace are stripped from input. +.Pp +Examples: +.Bd -literal -offset indent -compact +\&.\e\(dq This is a comment line. +\&.\e\(dq The next line is ignored: +\&. +\&.Sh EXAMPLES \e\(dq This is a comment, too. +\&example text \e\(dq And so is this. +.Ed +.Ss Special Characters +Special characters are used to encode special glyphs and are rendered +differently across output media. +They may occur in request, macro, and text lines. +Sequences begin with the escape character +.Sq \e +followed by either an open-parenthesis +.Sq \&( +for two-character sequences; an open-bracket +.Sq \&[ +for n-character sequences (terminated at a close-bracket +.Sq \&] ) ; +or a single one character sequence. +.Pp +Examples: +.Bl -tag -width Ds -offset indent -compact +.It Li \e(em +Two-letter em dash escape. +.It Li \ee +One-letter backslash escape. +.El +.Pp +See +.Xr mandoc_char 7 +for a complete list. +.Ss Text Decoration +Terms may be text-decorated using the +.Sq \ef +escape followed by an indicator: B (bold), I (italic), R (regular), or P +(revert to previous mode). +A numerical representation 3, 2, or 1 (bold, italic, and regular, +respectively) may be used instead. +The indicator or numerical representative may be preceded by C +(constant-width), which is ignored. +.Pp +The two-character indicator +.Sq BI +requests a font that is both bold and italic. +It may not be portable to old roff implementations. +.Pp +Examples: +.Bl -tag -width Ds -offset indent -compact +.It Li \efBbold\efR +Write in \fBbold\fP, then switch to regular font mode. +.It Li \efIitalic\efP +Write in \fIitalic\fP, then return to previous font mode. +.It Li \ef(BIbold italic\efP +Write in \f(BIbold italic\fP, then return to previous font mode. +.El +.Pp +Text decoration is +.Em not +recommended for +.Xr mdoc 7 , +which encourages semantic annotation. +.Ss Predefined Strings +Predefined strings, like +.Sx Special Characters , +mark special output glyphs. +Predefined strings are escaped with the slash-asterisk, +.Sq \e* : +single-character +.Sq \e*X , +two-character +.Sq \e*(XX , +and N-character +.Sq \e*[N] . +.Pp +Examples: +.Bl -tag -width Ds -offset indent -compact +.It Li \e*(Am +Two-letter ampersand predefined string. +.It Li \e*q +One-letter double-quote predefined string. +.El +.Pp +Predefined strings are not recommended for use, +as they differ across implementations. +Those supported by +.Xr mandoc 1 +are listed in +.Xr mandoc_char 7 . +Manuals using these predefined strings are almost certainly not portable. +.Ss Whitespace +Whitespace consists of the space character. +In text lines, whitespace is preserved within a line. +In request and macro lines, whitespace delimits arguments and is discarded. +.Pp +Unescaped trailing spaces are stripped from text line input unless in a +literal context. +In general, trailing whitespace on any input line is discouraged for +reasons of portability. +In the rare case that a blank character is needed at the end of an +input line, it may be forced by +.Sq \e\ \e& . +.Pp +Literal space characters can be produced in the output +using escape sequences. +In macro lines, they can also be included in arguments using quotation; see +.Sx MACRO SYNTAX +for details. +.Pp +Blank text lines, which may include whitespace, are only permitted +within literal contexts. +If the first character of a text line is a space, that line is printed +with a leading newline. +.Ss Scaling Widths +Many requests and macros support scaled widths for their arguments. +The syntax for a scaled width is +.Sq Li [+-]?[0-9]*.[0-9]*[:unit:] , +where a decimal must be preceded or followed by at least one digit. +Negative numbers, while accepted, are truncated to zero. +.Pp +The following scaling units are accepted: +.Pp +.Bl -tag -width Ds -offset indent -compact +.It c +centimetre +.It i +inch +.It P +pica (~1/6 inch) +.It p +point (~1/72 inch) +.It f +scale +.Sq u +by 65536 +.It v +default vertical span +.It m +width of rendered +.Sq m +.Pq em +character +.It n +width of rendered +.Sq n +.Pq en +character +.It u +default horizontal span for the terminal +.It M +mini-em (~1/100 em) +.El +.Pp +Using anything other than +.Sq m , +.Sq n , +or +.Sq v +is necessarily non-portable across output media. +See +.Sx COMPATIBILITY . +.Pp +If a scaling unit is not provided, the numerical value is interpreted +under the default rules of +.Sq v +for vertical spaces and +.Sq u +for horizontal ones. +.Pp +Examples: +.Bl -tag -width ".Bl -tag -width 2i" -offset indent -compact +.It Li \&.Bl -tag -width 2i +two-inch tagged list indentation in +.Xr mdoc 7 +.It Li \&.HP 2i +two-inch tagged list indentation in +.Xr man 7 +.It Li \&.sp 2v +two vertical spaces +.El +.Ss Sentence Spacing +Each sentence should terminate at the end of an input line. +By doing this, a formatter will be able to apply the proper amount of +spacing after the end of sentence (unescaped) period, exclamation mark, +or question mark followed by zero or more non-sentence closing +delimiters +.Po +.Sq \&) , +.Sq \&] , +.Sq \&' , +.Sq \&" +.Pc . +.Pp +The proper spacing is also intelligently preserved if a sentence ends at +the boundary of a macro line. +.Pp +Examples: +.Bd -literal -offset indent -compact +Do not end sentences mid-line like this. Instead, +end a sentence like this. +A macro would end like this: +\&.Xr mandoc 1 \&. +.Ed +.Sh REQUEST SYNTAX +A request or macro line consists of: +.Pp +.Bl -enum -compact +.It +the control character +.Sq \&. +or +.Sq \(aq +at the beginning of the line, +.It +optionally an arbitrary amount of whitespace, +.It +the name of the request or the macro, which is one word of arbitrary +length, terminated by whitespace, +.It +and zero or more arguments delimited by whitespace. +.El +.Pp +Thus, the following request lines are all equivalent: +.Bd -literal -offset indent +\&.ig end +\&.ig end +\&. ig end +.Ed +.Sh MACRO SYNTAX +Macros are provided by the +.Xr mdoc 7 +and +.Xr man 7 +languages and can be defined by the +.Sx \&de +request. +When called, they follow the same syntax as requests, except that +macro arguments may optionally be quoted by enclosing them +in double quote characters +.Pq Sq \(dq . +Quoted text, even if it contains whitespace or would cause +a macro invocation when unquoted, is always considered literal text. +Inside quoted text, pairs of double quote characters +.Pq Sq Qq +resolve to single double quote characters. +.Pp +To be recognised as the beginning of a quoted argument, the opening +quote character must be preceded by a space character. +A quoted argument extends to the next double quote character that is not +part of a pair, or to the end of the input line, whichever comes earlier. +Leaving out the terminating double quote character at the end of the line +is discouraged. +For clarity, if more arguments follow on the same input line, +it is recommended to follow the terminating double quote character +by a space character; in case the next character after the terminating +double quote character is anything else, it is regarded as the beginning +of the next, unquoted argument. +.Pp +Both in quoted and unquoted arguments, pairs of backslashes +.Pq Sq \e\e +resolve to single backslashes. +In unquoted arguments, space characters can alternatively be included +by preceding them with a backslash +.Pq Sq \e\~ , +but quoting is usually better for clarity. +.Pp +Examples: +.Bl -tag -width Ds -offset indent -compact +.It Li .Fn strlen \(dqconst char *s\(dq +Group arguments +.Qq const char *s +into one function argument. +If unspecified, +.Qq const , +.Qq char , +and +.Qq *s +would be considered separate arguments. +.It Li .Op \(dqFl a\(dq +Consider +.Qq \&Fl a +as literal text instead of a flag macro. +.El +.Sh REQUEST REFERENCE +The +.Xr mandoc 1 +.Nm +parser recognises the following requests. +For requests marked as "ignored" or "unsupported", any arguments are +ignored, and the number of arguments is not checked. +.Ss \&ab +Abort processing. +Currently unsupported. +.Ss \&ad +Set line adjustment mode. +It takes one argument to select normal, left, right, +or center adjustment for subsequent text. +Currently ignored. +.Ss \&af +Assign an output format to a number register. +Currently ignored. +.Ss \&aln +Create an alias for a number register. +Currently unsupported. +.Ss \&als +Create an alias for a request, string, macro, or diversion. +Currently unsupported. +.Ss \&am +Append to a macro definition. +The syntax of this request is the same as that of +.Sx \&de . +.Ss \&am1 +Append to a macro definition, switching roff compatibility mode off +during macro execution (groff extension). +The syntax of this request is the same as that of +.Sx \&de1 . +Since +.Xr mandoc 1 +does not implement +.Nm +compatibility mode at all, it handles this request as an alias for +.Sx \&am . +.Ss \&ami +Append to a macro definition, specifying the macro name indirectly +(groff extension). +The syntax of this request is the same as that of +.Sx \&dei . +.Ss \&ami1 +Append to a macro definition, specifying the macro name indirectly +and switching roff compatibility mode off during macro execution +(groff extension). +The syntax of this request is the same as that of +.Sx \&dei1 . +Since +.Xr mandoc 1 +does not implement +.Nm +compatibility mode at all, it handles this request as an alias for +.Sx \&ami . +.Ss \&as +Append to a user-defined string. +The syntax of this request is the same as that of +.Sx \&ds . +If a user-defined string with the specified name does not yet exist, +it is set to the empty string before appending. +.Ss \&as1 +Append to a user-defined string, switching roff compatibility mode off +during macro execution (groff extension). +The syntax of this request is the same as that of +.Sx \&ds1 . +Since +.Xr mandoc 1 +does not implement +.Nm +compatibility mode at all, it handles this request as an alias for +.Sx \&as . +.Ss \&asciify +Fully unformat a diversion. +Currently unsupported. +.Ss \&backtrace +Print a backtrace of the input stack. +This is a groff extension and currently ignored. +.Ss \&bd +Artificially embolden by repeated printing with small shifts. +Currently ignored. +.Ss \&bleedat +Set the BleedBox page parameter for PDF generation. +This is a Heirloom extension and currently ignored. +.Ss \&blm +Set a blank line trap. +Currently unsupported. +.Ss \&box +Begin a diversion without including a partially filled line. +Currently unsupported. +.Ss \&boxa +Add to a diversion without including a partially filled line. +Currently unsupported. +.Ss \&bp +Begin new page. +Currently ignored. +.Ss \&BP +Define a frame and place a picture in it. +This is a Heirloom extension and currently unsupported. +.Ss \&br +Break the output line. +See +.Xr man 7 +and +.Xr mdoc 7 . +.Ss \&break +Break out of a +.Sx \&while +loop. +Currently unsupported. +.Ss \&breakchar +Optional line break characters. +This is a Heirloom extension and currently ignored. +.Ss \&brnl +Break output line after next N input lines. +This is a Heirloom extension and currently ignored. +.Ss \&brp +Break and spread output line. +Currently, this is implemented as an alias for +.Sx \&br . +.Ss \&brpnl +Break and spread output line after next N input lines. +This is a Heirloom extension and currently ignored. +.Ss \&c2 +Change the no-break control character. +Currently unsupported. +.Ss \&cc +Change the control character. +Its syntax is as follows: +.Bd -literal -offset indent +.Pf .

character +.Pq Sq \e , +.It +a single ASCII character called the escape sequence identifier, +.It +and, with only a few exceptions, an argument. +.El +.Pp +Arguments can be given in the following forms; some escape sequence +identifiers only accept some of these forms as specified below. +The first three forms are called the standard forms. +.Bl -tag -width 2n +.It \&In brackets: Ic \&[ Ns Ar argument Ns Ic \&] +The argument starts after the initial +.Sq \&[ , +ends before the final +.Sq \&] , +and the escape sequence ends with the final +.Sq \&] . +.It Two-character argument short form: Ic \&( Ns Ar ar +This form can only be used for arguments +consisting of exactly two characters. +It has the same effect as +.Ic \&[ Ns Ar ar Ns Ic \&] . +.It One-character argument short form: Ar a +This form can only be used for arguments +consisting of exactly one character. +It has the same effect as +.Ic \&[ Ns Ar a Ns Ic \&] . +.It Delimited form: Ar C Ns Ar argument Ns Ar C +The argument starts after the initial delimiter character +.Ar C , +ends before the next occurrence of the delimiter character +.Ar C , +and the escape sequence ends with that second +.Ar C . +Some escape sequences allow arbitrary characters +.Ar C +as quoting characters, some restrict the range of characters +that can be used as quoting characters. +.El +.Pp +Upon function entry, +.Fa end +is expected to point to the escape sequence identifier. +The values passed in as +.Fa start +and +.Fa sz +are ignored and overwritten. +.Pp +By design, this function cannot handle those +.Xr roff 7 +escape sequences that require in-place expansion, in particular +user-defined strings +.Ic \e* , +number registers +.Ic \en , +width measurements +.Ic \ew , +and numerical expression control +.Ic \eB . +These are handled by +.Fn roff_res , +a private preprocessor function called from +.Fn roff_parseln , +see the file +.Pa roff.c . +.Pp +The function +.Fn mandoc_escape +is used +.Bl -dash -compact

files +.Pa term.c +and +.Pa html.c , +.It +and rarely externally by high-level utilities using the mandoc library, +for example +.Xr makewhatis 8 , +to purge escape sequences from text. +.El +.Sh RETURN VALUES +Upon function return, the pointer +.Fa end +is set to the character after the end of the escape sequence, +such that the calling higher-level parser can easily continue. +.Pp +For escape sequences taking an argument, the pointer +.Fa start +is set to the beginning of the argument and +.Fa sz +is set to the length of the argument. +For escape sequences not taking an argument, +.Fa start +is set to the character after the end of the sequence and +.Fa sz +is set to 0. +Both +.Fa start +and +.Fa sz +may be +.Dv NULL ; +in that case, the argument and the length are not returned. +.Pp +For sequences taking an argument, the function +.Fn mandoc_escape +returns one of the following values: +.Bl -tag -width 2n +.It Dv ESCAPE_FONT +The escape sequence +.Ic \ef +taking an

Dzonsons Aq Mt kristaps@bsd.lv +.An Ingo Schwarze Aq Mt schwarze@openbsd.org +.Sh BUGS +The function doesn't cleanly distinguish between sequences that are +valid and supported, valid and ignored, valid and unsupported, +syntactically invalid, or undefined. +For sequences that are ignored or unsupported, it doesn't tell +whether that deficiency is likely to cause major formatting problems +and/or loss of document content. +The function is already rather complicated and still parses some +sequences incorrectly. +. +.ig +For these sequences, the list given below specifies a starting string +and either the length of the argument or an ending character. +The argument starts after the starting string. +In the former case, the sequence ends with the end of the argument. +In the latter case, the argument ends before the ending character, +and the sequence ends with the ending character. +..
