About mdocml, the portable mandoc distribution
----------------------------------------------
The mandoc manpage compiler toolset is a suite of tools compiling
mdoc(7), the roff(7) macro language of choice for BSD manual pages,
and man(7), the predominant historical language for UNIX manuals.
The toolset does not yet implement man(1); that is only scheduled
for the next release, 1.13.2. It can, however, already serve to
translate source manpages to the output displayed by man(1).
For general information, see <http://mdocml.bsd.lv/>.
In this document, we describe the installation and deployment of
mandoc(1), first as a simple, standalone formatter, and then as part of
the man(1) system.
In case you have questions or want to provide feedback, read
<http://mdocml.bsd.lv/contact.html>. Consider subscribing to the
discuss@ mailing list mentioned on that page. If you intend to
help with the development of mandoc, consider subscribing to the
tech@ mailing list, too.
Enjoy using the mandoc toolset!
Ingo Schwarze, Karlsruhe, August 2014
Installation
------------
Before manually installing mandoc on your system, please check
whether the newest version of mandoc is already installed by default
or available via a binary package or a ports system. A list of the
latest bundled and ported versions of mandoc for various operating
systems is maintained at <http://mdocml.bsd.lv/ports.html>.
If mandoc is installed, you can check the version by running "mandoc -V".
The version contained in this distribution tarball is listed near
the beginning of the file "Makefile".
Regarding how packages and ports are maintained for your operating
system, please consult your operating system documentation.
To install mandoc manually, the following steps are needed:
1. Decide whether you want to build the base tools mandoc(1),
preconv(1) and demandoc(1) only or whether you also want to build the
database tools apropos(1) and makewhatis(8). For the latter,
the following dependencies are required:
1.1. The SQLite database system, see <http://sqlite.org/>.
The recommended version of SQLite is 3.8.4.3 or newer. The mandoc
toolset is known to work with version 3.7.5 or newer. Versions
older than 3.8.3 may not achieve full performance due to the
missing SQLITE_DETERMINISTIC optimization flag. Versions older
than 3.8.0 may not show full error information if opening a database
fails due to the missing sqlite3_errstr() API. Both are very minor
problems, apropos(1) is fully usable with SQLite 3.7.5. Versions
older than 3.7.5 may or may not work, they have not been tested.
1.2. The fts(3) directory traversion functions.
A compatibility version will be bundled for 1.13.2 but is not available
yet. If you want apropos(1) and makewhatis(8) but do not have fts(3),
please stay with mandoc 1.12.3 for now and upgrade first to 1.12.4,
then to 1.13.2 when these versionns are released. Be careful: the
glibc version of fts(3) is known to be broken on 32bit platforms,
see <https://sourceware.org/bugzilla/show_bug.cgi?id=15838>.
1.3. Marc Espie's ohash(3) library.
If your system does not have it, the bundled compatibility version
will be used, so you probably need not worry about it.
2. If you choose to build the database tools, too, decide whether
you also want to build the CGI program, man.cgi(8).
3. Read the beginning of the file "Makefile" from "USER SETTINGS"
to "END OF USER SETTINGS" and edit it as required. In particular,
disable "BUILD_TARGETS += db-build" if you do not want database
support or enable "BUILD_TARGETS += cgi-build" if you do want
the CGI program.
4. Run "make". No separate "./configure" or "make depend" steps
are needed. The former is run automatically by "make". The latter
is a maintainer target. If you merely want to build the released
version as opposed to doing active development, there is no need
to regenerate the dependency specifications. Any POSIX-compatible
make, in particular both BSD make and GNU make, should work.
5. Run "make -n install" and check whether everything will be
installed to the intended places. Otherwise, edit the *DIR variables
in the Makefile until it is.
6. Run "sudo make install". If you intend to build a binary
package using some kind of fake root mechanism, you may need a
command like "make DESTDIR=... install". Read the *-install targets
in the "Makefile" to understand how DESTDIR is used.
7. To set up a man.cgi(8) server, read its manual page.
8. To use mandoc(1) as your man(1) formatter, read the "Deployment"
section below.
Checking autoconfiguration quality
----------------------------------
If you want to check whether automatic configuration works well
on your platform, consider the following:
The mandoc package intentionally does not use GNU autoconf because
we consider that toolset a blatant example of overengineering that
is obsolete nowadays, since all modern operating systems are now
reasonably close to POSIX and do not need arcane shell magic any
longer. If your system does need such magic, consider upgrading
to reasonably modern POSIX-compliant tools rather than asking for
autoconf-style workarounds.
As far as mandoc is using any features not mandated by ANSI X3.159-1989
("ANSI C") or IEEE Std 1003.1-2008 ("POSIX") that some modern systems
do not have, we intend to provide autoconfiguration tests and
compat_*.c implementations. Please report any that turn out to be
missing. Note that while we do strive to produce portable code,
we do not slavishly restrict ourselves to POSIX-only interfaces.
For improved security and readability, we do use well-designed,
modern interfaces like reallocarray(3) even if they are still rather
uncommon, of course bundling compat_*.c implementations as needed.
Where mandoc is using ANSI C or POSIX features that some systems
still lack and that compat_*.c implementations can be provided for
without too much hassle, we will consider adding them, too, so
please report whatever is missing on your platform.
The following steps can be used to manually check the automatic
configuration on your platform:
1. Run "make clean".
2. Run "make config.h"
3. Read the file "config.log". It shows the compiler commands used
to test the libraries installed on your system and the standard
output and standard error output these commands produce. Watch out
for unexpected failures. Those are most likely to happen if headers
or libraries are installed in unusual places or interfaces defined
in unusual headers. You can also look at the file "config.h" and
check that no expected "#define HAVE_*" lines are missing. The
list of tests run can be found in the file "configure".
Deployment
----------
If you want to integrate the mandoc(1) tools with your existing
man(1) system as a formatter, then contact us first: on systems without
mandoc(1) as the default, you may have your work cut out for you!
Usually, you can have your default installation and mandoc(1) work right
alongside each other by using user-specific versions of the files
mentioned below.
0. Back up each file you want to change!
1. First see whether your system has "/etc/man.conf" or "/etc/manpath.conf"
(if it has neither, but man(1) is functional, then let us know) or,
if running as your own user, a per-user override file. In either
case, find where man(1) is executing nroff(1) or groff(1) to format
manuals. Replace these calls with mandoc(1).
2. Then make sure that man(1) isn't running preprocessors, so you may
need to replace tbl(1), eqn(1), and similar references with cat(1).
Some man(1) implementations, like that on Mac OSX, let you run "man -d"
to see how the formatter is invoked. Use this to test your changes. On
Mac OS X, for instance, man(1) will prepend all files with ".ll" and
".nr" to set the terminal size, so you need to pass "tail -n+2 |
mandoc(1)" to disregard them.
3. Finally, make sure that mandoc(1) is actually being invoked instead
of cached pages being pulled up. You can usually do this by commenting
out NOCACHE or similar.
mandoc(1) still has a long way to go in understanding non-trivial
low-level roff(7) markup embedded in some man(7) pages. On the BSD
systems using mandoc(1), third-party software is generally vetted
on whether it may be formatted with mandoc(1). If not, groff(1)
is pulled in as a dependency and used to install a pre-formatted
"catpage" intead of directly as manual page source.
For more background on switching operating systems to use mandoc(1)
instead of groff(1) to format manuals, see the two BSDCan presentations
by Ingo Schwarze:

This file lists the most important changes in the mdocml.bsd.lv distribution.
Changes in version 1.13.1, released on August 10, 2014
--- MAJOR NEW FEATURES ---
* A complete apropos(1)/makewhatis(8)/man.cgi(8) suite
based on SQLite3 is now included.
CAVEAT: This also requires a working fts(3) implementation.
If your system lacks that *and* you want apropos(1)/makewhatis(8),
stay with 1.12.3 for now, then go to 1.12.4 and 1.13.2.
* The roff(7) parser now provides an almost complete implementation
of numerical expressions.
* Warning and error messages have been improved in many ways.
Almost all fatal errors were downgraded to normal errors and some
even to warnings. Almost all messages now mention the macro where
the issue is detected and many indicate the workaround employed.
The mandoc(1) manual now includes a list explaining all messages.
--- MINOR NEW FEATURES ---
* The roff(7) parser now supports the .ami (append to macro with
indirectly specified name), .as (append to user-defined
string), .dei (define macro with indirectly specified name),
.ll (line length), and .rr (remove register) requests.
* The roff(7) parser now supports string comparison and numerical
conditionals in the .if and .ie requests.
* The roff parser now fully supports the \B (validate numerical
expression) and partially supports the \w (measure text width)
escape sequences.
* The terminal formatter now supports the \: (optional line break)
escape sequence.
* The roff parser now supports expansion of user-defined strings
involving indirect references.
* The roff(7) parser now handles some pre-defined read-only
number registers that occur in the pod2man(1) preamble.
* For backward compatibility, the mdoc(7) parser and formatters
now support the obsolete macros .En, .Es, .Fr, and .Ot.
* The mdoc(7) formatter non partially supports .Bd -centered.
* tbl(7) now handles leading and trailing vertical lines.
* The build system now provides fallback versions of strcasestr(3)
and strsep(3) for systems lacking them.
* The mdoc(7) manual now explains how various standards
supported by the .St macro are related to each other.
--- BUGFIXES ---
* In the roff(7) parser, several bugs were fixed with respect
to closing conditional blocks on macro lines.
* Parsing of roff(7) identifiers and escape sequences was improved
in multiple respects.
* In the mdoc(7) parser, the handling of defective document
prologues was improved in multiple ways.
* The mdoc(7) parser no longer skips content before the first section
header, and it no longer deletes non-.% content from .Rs blocks.
* In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
* In the mdoc(7) parser, handling of .Sm with missing or invalid
arguments was corrected.
* In the mdoc(7) parser, trailing punctuation at the end of partial
implicit macros no longer triggers end-of-sentence spacing.
* In the terminal formatter, two crashes were fixed: one triggered by
excessive indentation and another by excessively long .Nm arguments.
* In the terminal formatter, a floating point rounding bug was
fixed that sometimes caused an off-by-one error in indentation.
* In the UTF-8 formatter, rendering of accents, breakable hyphens,
and non-breakable spaces was corrected.
* In the HTML formatter, encoding of special characters was
corrected in multiple respects.
* In the mdoc(7) formatter, rendering of .Ex and .Rv was
improved for various edge cases.
* In the mdoc(7) formatter, handling of empty .Bl -inset item
heads was improved.
* In the man(7) formatter, some bugs were fixed with respect
to same-line detection in the context of .TP and .nf macros,
and the indentation of .IP and .TP blocks was improved.
* The mandoc(3) library no longer prints to stderr.

Fixing this will probably require reworking the whole bufcat() concept.

Besides, groff has bug causing text right *before* .Bd -centered

- check whether it is correct that `D1' uses INDENT+1;

- prohibit `Nm' from having non-text HEAD children
(e.g., NetBSD mDNSShared/dns-sd.1)
(mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
- support translated section names
e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
that one uses NOMBRE because it is spanish...
deraadt tends to think that section-dependent macro behaviour
is a bad idea in the first place, so this may be irrelevant
- When there is free text in the SYNOPSIS and that free text contains
the .Nm macro, groff somehow understands to treat the .Nm as an in-line
macro, while mandoc treats it as a block macro and breaks the line.

- The whatis(1) utility looks for whole words in Nm.
If the file name of a page does not agree with the contents of any
of its Nm macros (e.g. pool(9)), add the file name as an Nm entry
to the mandoc.db as well, such that whatis(1) finds it.
If there is a page with a file name that does not appear as a substring
neither in Nm nor in Nd, the same fix would allow finding that page
with apropos(1) using the file name as a key, as well.

- When makewhatis(8) encounters a FATAL parse error,
it silently treats the file as formatted, which makes no sense
at all for paths like man1/foo.1 - and which also contradicts
what the manual says at the end of the description.

.Sh NAME
.Nm apropos ,
.Nm whatis
.Nd search manual page databases
.Sh SYNOPSIS
.Nm
.Op Fl C Ar file
.Op Fl M Ar path
.Op Fl m Ar path
.Op Fl O Ar outkey
.Op Fl S Ar arch
.Op Fl s Ar section
.Ar expression ...
.Sh DESCRIPTION
The
.Nm apropos
and
.Nm whatis
utilities query manual page databases generated by
.Xr makewhatis 8 ,
evaluating
.Ar expression
for each file in each database.
By default, it displays the names, section numbers, and description lines
of all matching manuals.
.Pp
By default,
.Nm
searches for
.Xr makewhatis 8
databases in the default paths stipulated by
.Xr man 1
and uses case-insensitive substring matching
.Pq the Cm = No operator
over manual names and descriptions
.Pq the Li \&Nm No and Li \&Nd No macro keys .
Multiple terms imply pairwise
.Fl o .
.Nm whatis
maps terms only to case-sensitive manual names.
.Pp
Its arguments are as follows:
.Bl -tag -width Ds
.It Fl C Ar file
Specify an alternative configuration
.Ar file
in
.Xr man.conf 5
format.
.It Fl M Ar path
Use the colon-separated path instead of the default list of paths
searched for
.Xr makewhatis 8
databases.
Invalid paths, or paths without manual databases, are ignored.
.It Fl m Ar path
Prepend the colon-separated paths to the list of paths searched
for
.Xr makewhatis 8
databases.
Invalid paths, or paths without manual databases, are ignored.
.It Fl O Ar outkey
Show the values associated with the key
.Ar outkey
instead of the manual descriptions.
.It Fl S Ar arch
Restrict the search to pages for the specified
.Xr machine 1
architecture.
.Ar arch
is case insensitive.
By default, pages for all architectures are shown.
.It Fl s Ar section
Restrict the search to the specified section of the manual.
By default, pages from all sections are shown.
See
.Xr man 1
for a listing of sections.
.El
.Pp
An
.Ar expression
consists of search terms joined by logical operators
.Fl a
.Pq and
and
.Fl o
.Pq or .
The
.Fl a
operator has precedence over
.Fl o
and both are evaluated left-to-right.
.Bl -tag -width Ds
.It \&( Ar expr No \&)
True if the subexpression
.Ar expr
is true.
.It Ar expr1 Fl a Ar expr2
True if both
.Ar expr1
and
.Ar expr2
are true (logical
.Sq and ) .
.It Ar expr1 Oo Fl o Oc Ar expr2
True if
.Ar expr1
and/or
.Ar expr2
evaluate to true (logical
.Sq or ) .
.It Ar term
True if
.Ar term
is satisfied.
This has syntax
.Sm off
.Oo
.Op Ar key Op , Ar key ...
.Pq Cm = | ~
.Oc
.Ar val ,
.Sm on
where
.Ar key
is an
.Xr mdoc 7
macro to query and
.Ar val
is its value.
See
.Sx Macro Keys
for a list of available keys.
Operator
.Cm =
evaluates a substring, while
.Cm ~
evaluates a regular expression.
.It Fl i Ar term
If
.Ar term
is a regular expression, it
is evaluated case-insensitively.
Has no effect on substring terms.
.El
.Pp
.Nm whatis
considers an
.Ar expression
to consist of an opaque keyword.
.Pp
Results are sorted by manual sections and names, with output formatted as
.Pp
.D1 name[, name...](sec) \- description
.Pp
Where
.Dq name
is the manual's name,
.Dq sec
is the manual section, and
.Dq description
is the manual's short description.
If an architecture is specified for the manual, it is displayed as
.Pp
.D1 name(sec/arch) \- description
.Pp
Resulting manuals may be accessed as
.Pp
.Dl $ man \-s sec name
.Pp
If an architecture is specified in the output, use
.Pp
.Dl $ man \-s sec \-S arch name
.Ss Macro Keys
Queries evaluate over a subset of
.Xr mdoc 7
macros indexed by
.Xr makewhatis 8 .
In addition to the macro keys listed below, the special key
.Cm any
may be used to match any available macro key.
.Pp
Names and description:
.Bl -column "xLix" description -offset indent -compact
.It Li \&Nm Ta manual name
.It Li \&Nd Ta one-line manual description
.It Li arch Ta machine architecture (case-insensitive)

.It Li \&Sh Ta section header (excluding standard sections)
.It Li \&Ss Ta subsection header
.It Li \&Xr Ta cross reference to another manual page
.It Li \&Rs Ta bibliographic reference

.El
.Sh ENVIRONMENT
.Bl -tag -width MANPATH
.It Ev MANPATH
The standard search path used by
.Xr man 1
may be changed by specifying a path in the
.Ev MANPATH
environment variable.
Invalid paths, or paths without manual databases, are ignored.
Overridden by
.Fl M .
If
.Ev MANPATH
begins with a colon, it is appended to the default list;
if it ends with a colon, it is prepended to the default list;
or if it contains two adjacent colons,
the standard search path is inserted between the colons.
If none of these conditions are met, it overrides the
standard search path.
.El
.Sh FILES
.Bl -tag -width "/etc/man.conf" -compact
.It Pa mandoc.db
name of the
.Xr makewhatis 8
keyword database
.It Pa /etc/man.conf
default
.Xr man 1
configuration file
.El
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
Search for
.Qq .cf
as a substring of manual names and descriptions:
.Pp
.Dl $ apropos .cf
.Pp
Include matches for
.Qq .cnf
and
.Qq .conf
as well:
.Pp
.Dl $ apropos .cf .cnf .conf
.Pp
Search in names and descriptions using a regular expression:
.Pp
.Dl $ apropos '~set.?[ug]id'
.Pp
Search for manuals in the library section mentioning both the
.Qq optind
and the
.Qq optarg
variables:
.Pp
.Dl $ apropos \-s 3 Va=optind \-a Va=optarg
.Pp
Do exactly the same as calling
.Xr whatis 1
with the argument
.Qq ssh :
.Pp
.Dl $ apropos \-\- \-i 'Nm~[[:<:]]ssh[[:>:]]'
.Pp
The following two invocations are equivalent:
.Pp
.D1 Li $ apropos -S Ar arch Li -s Ar section expression
.Bd -ragged -offset indent
.Li $ apropos \e( Ar expression Li \e)
.Li -a arch~^( Ns Ar arch Ns Li |any)$
.Li -a sec~^ Ns Ar section Ns Li $

.Sh DESCRIPTION
The
.Nm
utility extracts keywords from
.Ux
manuals and indexes them in a database for fast retrieval by
.Xr apropos 1 ,
.Xr whatis 1 ,
and
.Xr man 1 Ns 's
.Fl k
option.
.Pp
By default,
.Nm
creates a database in each
.Ar dir
using the files
.Sm off
.Sy man Ar section Li /
.Op Ar arch Li /
.Ar title . section
.Sm on
and
.Sm off
.Sy cat Ar section Li /
.Op Ar arch Li /
.Ar title . Sy 0
.Sm on
in that directory.
Existing databases are replaced.
If
.Ar dir
is not provided,
.Nm
uses the default paths stipulated by
.Xr manpath 1 ,
or
.Xr man.conf 5 .
.Pp
The arguments are as follows:
.Bl -tag -width "-C file"
.It Fl a
Use all directories and files found below
.Ar dir ... .
.It Fl C Ar file
Specify an alternative configuration
.Ar file
in
.Xr man.conf 5
format.
.It Fl D
Display all files added or removed to the index.
With a second
.Fl D ,
also show all keyswords added for each file.
.It Fl d Ar dir
Merge (remove and re-add)
.Ar
to the database in
.Ar dir .
.It Fl n
Do not create or modify any database; scan and parse only,
and print manual page names and descriptions to standard output.
.It Fl p
Print warnings about potential problems with manual pages
to the standard error output.
.It Fl Q
Quickly build reduced-size databases
by reading only the NAME sections of manuals.
The resulting databases will usually contain names and descriptions only.
.It Fl T Cm utf8
Use UTF-8 encoding instead of ASCII for strings stored in the databases.
.It Fl t Ar
Check the given
.Ar files
for potential problems.
Implies
.Fl a ,
.Fl n ,
and
.Fl p .
All diagnostic messages are printed to the standard output;
the standard error output is not used.
.It Fl u Ar dir
Remove
.Ar
from the database in
.Ar dir .
.El
.Pp
If fatal parse errors are encountered while parsing, the offending file
is printed to stderr, omitted from the index, and the parse continues
with the next input file.
.Sh FILES
.Bl -tag -width Ds
.It Pa mandoc.db
A database of manpages relative to the directory of the file.
This file is portable across architectures and systems, so long as the
manpage hierarchy it indexes does not change.
.It Pa /etc/man.conf
The default
.Xr man 1
configuration file.
.El
.Sh EXIT STATUS
The
.Nm
utility exits with one of the following values:
.Pp
.Bl -tag -width Ds -compact
.It 0
No errors occurred.
.It 5
Invalid command line arguments were specified.
No input files have been read.
.It 6
An operating system error occurred, for example memory exhaustion or an
error accessing input files.
Such errors cause
.Nm
to exit at once, possibly in the middle of parsing or formatting a file.
The output databases are corrupt and should be removed.

.Sh HISTORY
A
.Nm
utility first appeared in
.Bx 2 .
It was rewritten in
.Xr perl 1
for
.Ox 2.7
and in C for
.Ox 5.6 .
.Pp
The
.Ar dir
argument first appeared in
.Nx 1.0 ;
the options
.Fl dpt
in
.Ox 2.7 ;
the option
.Fl u
in
.Ox 3.4 ;
and the options
.Fl aCDnQT
in
.Ox 5.6 .

.Nm
in February 1979,
.An Marc Espie
started the Perl version in 2000,
and the current version of

.Dt MAN.CGI 8
.Os
.Sh NAME
.Nm man.cgi
.Nd CGI program to search and display manual pages
.Sh DESCRIPTION
The
.Nm
CGI program searches for manual pages on a WWW server
and displays them to HTTP clients,
providing functionality equivalent to the
.Xr apropos 1
and
.Xr man 1
utilities.
It can use multiple manual trees in parallel.
.Ss HTML search interface
At the top of each generated HTML page,
.Nm
displays a search form containing these elements:
.Bl -enum
.It
An input box for search queries, expecting
either a name of a manual page or an
.Ar expression
using the syntax described in the
.Xr apropos 1
manual; filling this in is required for each search.
.It
A
.Dq Submit
button to send a search request from the client to the server.
.It
A
.Dq Reset
button to undo any changes to the input boxes and the dropdown menus
and reset them to the values contained in the
.Ev QUERY_STRING .
.It
Radio buttons to select pages either by name like in
.Xr man 1
or using
.Xr apropos 1
queries.
.It
A dropdown menu to optionally select a manual section.
If one is provided, it has the same effect as the
.Xr man 1
and
.Xr apropos 1
.Fl s
option.
Otherwise, pages from all sections are shown.
.It
A dropdown menu to optionally select an architecture.
If one is provided, it has the same effect as the
.Xr man 1
and
.Xr apropos 1
.Fl S
option.
By default, pages for all architectures are shown.
.It
A dropdown menu to select a manual tree.
If the configuration file
.Pa /var/www/man/manpath.conf
contains only one manpath, the dropdown menu is not shown.
By default, the first manpath given in the file is used.
.El
.Ss Program output
The
.Nm
program generates five kinds of output pages:
.Bl -tag -width Ds
.It The index page.
This is returned when calling
.Nm
without
.Ev PATH_INFO
and without a
.Ev QUERY_STRING .
It serves as a starting point for using the program
and shows the search form only.
.It A list page.
Lists are returned when searches match more than one manual page.
The first column shows the names and section numbers of manuals
as clickable links.
The second column shows the one-line descriptions of the manuals.
.It A manual page.
This output format is used when a search matches exactly one
manual page, or when a link on a list page or an
.Ic \&Xr
link on another manual page is followed.
.It A no-result page.
This is shown when a search request returns no results -
eiher because it violates the query syntax, or because
the search does not match any manual pages.
.It \&An error page.
This cannot happen by merely clicking the
.Dq Search
button, but only by manually entering an invalid URI.
It does not show the search form, but only an error message
and a link back to the index page.
.El
.Ss Setup
For each manual tree, create one first-level subdirectory below
.Pa /var/www/man .
The name of one of these directories is called a
.Dq manpath
in the context of
.Nm .
Create a single ASCII text file
.Pa /var/www/man/manpath.conf
containing the names of these directories, one per line.
The directory given first is used as the default manpath.
.Pp
Inside each of these directories, use the same directory and file
structure as found below
.Pa /usr/share/man ,
that is, second-level subdirectories
.Pa /var/www/man/*/man1 , /var/www/man/*/man2
etc. containing source
.Xr mdoc 7
and
.Xr man 7
manuals with file name extensions matching the section numbers,
second-level subdirectories
.Pa /var/www/man/*/cat1 , /var/www/man/*/cat2
etc. containing preformatted manuals with the file name extension
.Sq 0 ,
and optional third-level subdirectories for architectures.
Use
.Xr makewhatis 8
to create a
.Xr mandoc.db 5
database inside each manpath.
.Pp
Configure your web server to execute CGI programs located in
.Pa /cgi-bin .
When using
.Xr nginx 8 ,
the
.Xr slowcgi 8
proxy daemon is needed to translate FastCGI requests to plain old CGI.
.Pp
To compile
.Nm ,
first copy
.Pa cgi.h.example
to
.Pa cgi.h
and edit it according to your needs.
It contains the following compile-time definitions:
.Bl -tag -width Ds
.It Ev COMPAT_OLDURI
Only useful for running on www.openbsd.org to deal with old URIs containing
.Qq "manpath=OpenBSD "
where the blank character has to be translated to a hyphen.
When compiling for other sites, this definition can be deleted.
.It Ev CSS_DIR
An optional path to the directory containing the CSS files,
to be specified relative to the server's document root,
and to be specified without a trailing slash.
When not specified, the CSS files
are assumed to be in the document root.
This is used in generated HTML code.
.It Ev CUSTOMIZE_BEGIN
A HTML string to be inserted right after opening the
.Aq BODY
element.
.It Ev CUSTOMIZE_TITLE
An ASCII string to be used for the HTML
.Aq TITLE
element.
.It Ev HTTP_HOST
The FQDN of the (possibly virtual) host the HTTP server is running on.
This is used for
.Ic Location:
headers in HTTP 303 responses.
.It Ev MAN_DIR
A path to the
.Nm
data directory to be used instead of
.Pa /var/www/man ,
relative to the web server
.Xr chroot 2
directory, to be specified without a trailing slash.
This is prepended to the manpath when opening
.Xr mandoc.db 5
and manual page files.
.El
.Pp
After editing
.Pa cgi.h ,
run
.Pp
.Dl make man.cgi
.Pp
and copy the files to the proper locations.
Reading the
.Cm installcgi
target in the
.Pa Makefile
can help with that, but do not run it without carefully checking it
because the directory layouts of web servers vary greatly.
.Ss URI interface
.Nm
uniform resource identifiers are not needed for interactive use,
but can be useful for deep linking.
They consist of:
.Bl -enum
.It
The
.Cm http://
protocol specifier.
.It
The host name and a following slash.
.It
The path to the program, normally
.Pa cgi-bin/man.cgi/ .
.It
To show a single page, a slash, the manpath, another slash,
and the name of the requested file, for example
.Pa /OpenBSD-current/man1/mandoc.1 .
.It
For searches, a query string starting with a question mark
and consisting of
.Ar key Ns = Ns Ar value
pairs, separated by ampersands, for example
.Pa ?manpath=OpenBSD-current&query=mandoc .
Supported keys are
.Cm manpath ,
.Cm query ,
.Cm sec ,
.Cm arch ,
corresponding to
.Xr apropos 1
.Fl M ,
.Ar expression ,
.Fl s ,
.Fl S ,
respectively, and
.Cm apropos ,
which is a boolean parameter to select or deselect the
.Xr apropos 1
query mode.
For backward compatibility with the traditional
.Nm ,
.Cm sektion
is supported as an alias for
.Cm sec .
.El
.Ss Restricted character set
For security reasons, in particular to prevent cross site scripting
attacks, some strings used by
.Nm
can only contain the following characters:
.Pp
.Bl -dash -compact -offset indent
.It
lower case and upper case ASCII letters
.It
the ten decimal digits
.It
the dash
.Pq Sq -
.It
the dot
.Pq Sq \&.
.It
the slash
.Pq Sq /
.It
the underscore
.Pq Sq _
.El
.Pp
In particular, this applies to the
.Ev SCRIPT_NAME ,
to all manpaths, and to all architecture names.
.Sh ENVIRONMENT
The web server may pass the following CGI variables to
.Nm :
.Bl -tag -width Ds
.It Ev PATH_INFO
The final part of the URI path passed from the client to the server,
starting after the
.Ev SCRIPT_NAME
and ending before the
.Ev QUERY_STRING .
It is used by the
.Cm show
page to aquire the manpath and filename it needs.
.It Ev QUERY_STRING
The HTTP query string passed from the client to the server.
It is the final part of the URI, after the question mark.
It is used by the
.Cm search
page to acquire the named parameters it needs.
.It Ev SCRIPT_NAME
The path to the
.Nm
binary relative to the server root, usually
.Pa /cgi-bin/man.cgi .
This is used for generating URIs to be embedded
in generated HTML code and HTTP headers.
If this contains any character not contained in the
.Sx Restricted character set ,
.Nm
reports an internal server error and exits without doing anything.
.El
.Sh FILES
.Bl -tag -width Ds
.It Pa /var/www
Default web server
.Xr chroot 2
directory.
All the following paths are specified relative to this directory.
.It Pa /cgi-bin/man.cgi
The path to the
.Nm
program relative to the server root.
Can be overridden by
.Ev SCRIPT_NAME .
.It Pa /htdocs
The path to the server document root relative to the server root.
This is part of the web server configuration and not specific to
.Nm .
.It Pa /htdocs/man-cgi.css
A style sheet for general
.Nm
styling, referenced from each generated HTML page.
.It Pa /htdocs/man.css
A style sheet for
.Xr mandoc 1
HTML styling, referenced from each generated HTML page after
.Pa man-cgi.css .
.It Pa /man
Default
.Nm
data directory containing all the manual trees.
Can be overridden by
.Ev MAN_DIR .
.It Pa /man/mandoc/man1/apropos.1 , /man/mandoc/man8/man.cgi.8
Manual pages documenting
.Nm
itself, linked from the index page.
.It Pa /man/manpath.conf
The list of available manpaths, one per line.
If any of the lines in this file contains a slash
.Pq Sq /
or any character not contained in the
.Sx Restricted character set ,
.Nm
reports an internal server error and exits without doing anything.
.It Pa /man/OpenBSD-current/man1/mandoc.1
An example
.Xr mdoc 7
source file located below the
.Dq OpenBSD-current
manpath.
.El
.Sh COMPATIBILITY
The
.Nm
CGI program is call-compatible with queries from the traditional
.Pa man.cgi
script by Wolfram Schneider.
However, the output may not be quite the same.
.Sh SEE ALSO
.Xr apropos 1 ,
.Xr mandoc.db 5 ,
.Xr makewhatis 8 ,
.Xr slowcgi 8

.It Sy "missing manual title, using UNTITLED"
.Pq mdoc
A
.Ic \&Dt
macro has no arguments, or there is no
.Ic \&Dt
macro before the first non-prologue macro.
.It Sy "missing manual title, using \(dq\(dq"
.Pq man
There is no
.Ic \&TH
macro, or it has no arguments.
.It Sy "lower case character in document title"
.Pq mdoc , man
The title is still used as given in the
.Ic \&Dt
or
.Ic \&TH
macro.
.It Sy "missing manual section, using \(dq\(dq"
.Pq mdoc , man
A
.Ic \&Dt
or
.Ic \&TH
macro lacks the mandatory section argument.
.It Sy "unknown manual section"
.Pq mdoc
The section number in a
.Ic \&Dt
line is invalid, but still used.
.It Sy "unknown manual volume or arch"
.Pq mdoc
The volume name in a
.Ic \&Dt
line is invalid, but still used.
The manual is assumed to be architecture-independent.
.It Sy "missing date, using today's date"
.Pq mdoc, man
The document was parsed as
.Xr mdoc 7
and it has no
.Ic \&Dd
macro, or the
.Ic \&Dd
macro has no arguments or only empty arguments;
or the document was parsed as
.Xr man 7
and it has no
.Ic \&TH
macro, or the
.Ic \&TH
macro has less than three arguments or its third argument is empty.
.It Sy "cannot parse date, using it verbatim"
.Pq mdoc , man
The date given in a
.Ic \&Dd
or
.Ic \&TH
macro does not follow the conventional format.
.It Sy "missing Os macro, using \(dq\(dq"
.Pq mdoc
The default or current system is not shown in this case.
.It Sy "duplicate prologue macro"
.Pq mdoc
One of the prologue macros occurs more than once.
The last instance overrides all previous ones.
.It Sy "late prologue macro"
.Pq mdoc
A
.Ic \&Dd
or
.Ic \&Os
macro occurs after some non-prologue macro, but still takes effect.
.It Sy "skipping late title macro"
.Pq mdoc
The
.Ic \&Dt
macro can only occur before the first non-prologue macro
because traditional formatters write the page header
before parsing the document body.
Even though this technical restriction does not apply to
.Nm ,
traditional semantics is preserved.
The late macro is discarded including its arguments.
.It Sy "prologue macros out of order"
.Pq mdoc
The prologue macros are not given in the conventional order
.Ic \&Dd ,
.Ic \&Dt ,
.Ic \&Os .
All three macros are used even when given in another order.
.El
.Ss Warnings regarding document structure
.Bl -ohang
.It Sy ".so is fragile, better use ln(1)"
.Pq roff
Including files only works when the parser program runs with the correct
current working directory.
.It Sy "no document body"
.Pq mdoc , man
The document body contains neither text nor macros.
An empty document is shown, consisting only of a header and a footer line.
.It Sy "content before first section header"
.Pq mdoc , man
Some macros or text precede the first
.Ic \&Sh
or
.Ic \&SH
section header.
The offending macros and text are parsed and added to the top level
of the syntax tree, outside any section block.
.It Sy "first section is not NAME"
.Pq mdoc
The argument of the first
.Ic \&Sh
macro is not
.Sq NAME .
This may confuse
.Xr makewhatis 8
and
.Xr apropos 1 .
.It Sy "bad NAME section contents"
.Pq mdoc
The last node in the NAME section is not an
.Ic \&Nd
macro, or any preceding macro is not
.Ic \&Nm ,
or the NAME section is completely empty.
This may confuse
.Xr makewhatis 8
and
.Xr apropos 1 .
.It Sy "sections out of conventional order"
.Pq mdoc
A standard section occurs after another section it usually precedes.
All section titles are used as given,
and the order of sections is not changed.
.It Sy "duplicate section title"
.Pq mdoc
The same standard section title occurs more than once.
.It Sy "unexpected section"
.Pq mdoc
A standard section header occurs in a section of the manual
where it normally isn't useful.

manual for replacements.
.It Sy "skipping paragraph macro"
In
.Xr mdoc 7
documents, this happens
.Bl -dash -compact
.It
at the beginning and end of sections and subsections
.It
right before non-compact lists and displays
.It
at the end of items in non-column, non-compact lists
.It
and for multiple consecutive paragraph macros.
.El
In

documents, it happens
.Bl -dash -compact
.It
for empty
.Ic \&P ,
.Ic \&PP ,
and
.Ic \&LP
macros
.It
for
.Ic \&IP
macros having neither head nor body arguments
.It
for
.Ic \&br
or
.Ic \&sp
right after
.Ic \&SH
or
.Ic \&SS
.El
.It Sy "moving paragraph macro out of list"
.Pq mdoc
A list item in a
.Ic \&Bl
list contains a trailing paragraph macro.
The paragraph macro is moved after the end of the list.
.It Sy "skipping no-space macro"
.Pq mdoc
An input line begins with an
.Ic \&Ns
macro.
The macro is ignored.
.It Sy "blocks badly nested"
.Pq mdoc
If two blocks intersect, one should completely contain the other.
Otherwise, rendered output is likely to look strange in any output
format, and rendering in SGML-based output formats is likely to be
outright wrong because such languages do not support badly nested
blocks at all.
Typical examples of badly nested blocks are
.Qq Ic \&Ao \&Bo \&Ac \&Bc
and
.Qq Ic \&Ao \&Bq \&Ac .
In these examples,
.Ic \&Ac
breaks
.Ic \&Bo
and
.Ic \&Bq ,
respectively.
.It Sy "nested displays are not portable"
.Pq mdoc
A
.Ic \&Bd ,
.Ic \&D1 ,
or
.Ic \&Dl
display occurs nested inside another
.Ic \&Bd
display.
This works with
.Nm ,
but fails with most other implementations.
.It Sy "moving content out of list"
.Pq mdoc
A
.Ic \&Bl
list block contains text or macros before the first
.Ic \&It
macro.
The offending children are moved before the beginning of the list.
.It Sy ".Vt block has child macro"
.Pq mdoc
The
.Ic \&Vt
macro supports plain text arguments only.
Formatting may be ugly and semantic searching
for the affected content might not work.
.It Sy "fill mode already enabled, skipping"
.Pq man
A
.Ic \&fi
request occurs even though the document is still in fill mode,
or already switched back to fill mode.
It has no effect.
.It Sy "fill mode already disabled, skipping"
.Pq man
An
.Ic \&nf
request occurs even though the document already switched to no-fill mode
and did not switch back to fill mode yet.
It has no effect.
.It Sy "line scope broken"
.Pq man
While parsing the next-line scope of the previous macro,
another macro is found that prematurely terminates the previous one.
The previous, interrupted macro is deleted from the parse tree.
.El
.Ss "Warnings related to missing arguments"
.Bl -ohang
.It Sy "skipping empty request"
.Pq roff
The macro name is missing from a macro definition request.
.It Sy "conditional request controls empty scope"
.Pq roff
A conditional request is only useful if any of the following
follows it on the same logical input line:
.Bl -dash -compact
.It
The
.Sq \e{
keyword to open a multi-line scope.
.It
A request or macro or some text, resulting in a single-line scope.
.It
The immediate end of the logical line without any intervening whitespace,
resulting in next-line scope.
.El
Here, a conditional request is followed by trailing whitespace only,
and there is no other content on its logical input line.
Note that it doesn't matter whether the logical input line is split
across multiple physical input lines using
.Sq \e
line continuation characters.
This is one of the rare cases
where trailing whitespace is syntactically significant.
The conditional request controls a scope containing whitespace only,
so it is unlikely to have a significant effect,
except that it may control a following
.Ic \&el
clause.
.It Sy "skipping empty macro"
.Pq mdoc
The indicated macro has no arguments and hence no effect.
.It Sy "empty argument, using 0n"
.Pq mdoc
The required width is missing after
.Ic \&Bd
or
.Ic \&Bl
.Fl offset
or
.Fl width.
.It Sy "argument count wrong"
.Pq mdoc , man
The indicated macro has too few or too many arguments.
The syntax tree will contain the wrong number of arguments as given.
Formatting behaviour depends on the specific macro in question.
Note that the same message may also occur as an ERROR, see below.
.It Sy "missing display type, using -ragged"
.Pq mdoc
The
.Ic \&Bd
macro is invoked without the required display type.
.It Sy "list type is not the first argument"
.Pq mdoc
In a
.Ic \&Bl
macro, at least one other argument precedes the type argument.
The
.Nm
utility may also print messages related to invalid command line arguments
or operating system errors, for example when memory is exhausted or
input files cannot be read.
Such messages do not carry the prefix described above.
utility copes with any argument order, but some other
.Xr mdoc 7
implementations do not.
.It Sy "missing -width in -tag list, using 8n"
.Pq mdoc
Every
.Ic \&Bl
macro having the
.Fl tag
argument requires
.Fl width ,
too.
.It Sy "missing utility name, using \(dq\(dq"
.Pq mdoc
The
.Ic \&Ex Fl std
macro is called without an argument before
.Ic \&Nm
has first been called with an argument.
.It Sy "empty head in list item"
.Pq mdoc
In a
.Ic \&Bl
.Fl diag ,
.Fl hang ,
.Fl inset ,
.Fl ohang ,
or
.Fl tag
list, an
.Ic \&It
macro lacks the required argument.
The item head is left empty.
.It Sy "empty list item"
.Pq mdoc
In a
.Ic \&Bl
.Fl bullet ,
.Fl dash ,

.It Sy "unterminated quoted argument"
.Pq roff
Macro arguments can be enclosed in double quote characters
such that space characters and macro names contained in the quoted
argument need not be escaped.
The closing quote of the last argument of a macro can be omitted.
However, omitting it is not recommended because it makes the code
harder to read.
.It Sy "duplicate argument"
.Pq mdoc
A
.Ic \&Bd
or
.Ic \&Bl
macro has more than one
.Fl compact ,
more than one
.Fl offset ,
or more than one

All but the last instances of these arguments are ignored.
.It Sy "skipping duplicate argument"

All but the first of these arguments are ignored.
.It Sy "skipping duplicate display type"

That has no effect.
.It Sy "unknown AT&T UNIX version"
.Pq mdoc
An
.Ic \&At
macro has an invalid argument.
It is used verbatim, with
.Qq "AT&T UNIX "
prefixed to it.
.It Sy "invalid content in Rs block"
.Pq mdoc
An
.Ic \&Rs
block contains plain text or non-% macros.
The bogus content is left in the syntax tree.
Formatting may be poor.
.It Sy "invalid Boolean argument"
.Pq mdoc
An
.Ic \&Sm
macro has an argument other than
.Cm on
or
.Cm off .
The invalid argument is moved out of the macro, which leaves the macro
empty, causing it to toggle the spacing mode.

.Ic \&ft
request has an invalid argument.
.El
.Ss "Warnings related to plain text"
.Bl -ohang
.It Sy "blank line in fill mode, using .sp"
.Pq mdoc
The meaning of blank input lines is only well-defined in non-fill mode:
In fill mode, line breaks of text input lines are not supposed to be
significant.
However, for compatibility with groff, blank lines in fill mode
are replaced with
.Ic \&sp
requests.
.It Sy "tab in filled text"
.Pq mdoc , man
The meaning of tab characters is only well-defined in non-fill mode:
In fill mode, whitespace is not supposed to be significant
on text input lines.
As an implementation dependent choice, tab characters on text lines
are passed through to the formatters in any case.
Given that the text before the tab character will be filled,
it is hard to predict which tab stop position the tab will advance to.
.It Sy "whitespace at end of input line"
.Pq mdoc , man , roff
Whitespace at the end of input lines is almost never semantically
significant \(em but in the odd case where it might be, it is
extremely confusing when reviewing and maintaining documents.
.It Sy "bad comment style"
.Pq roff
Comment lines start with a dot, a backslash, and a double-quote character.
The
.Nm
utility treats the line as a comment line even without the backslash,
but leaving out the backslash might not be portable.
.It Sy "invalid escape sequence"
.Pq roff
An escape sequence has an invalid opening argument delimiter, lacks the
closing argument delimiter, or the argument has too few characters.
If the argument is incomplete,
.Ic \e*
and
.Ic \en
expand to an empty string,
.Ic \eB
to the digit
.Sq 0 ,
and
.Ic \ew
to the length of the incomplete argument.
All other invalid escape sequences are ignored.
.It Sy "undefined string, using \(dq\(dq"
.Pq roff
If a string is used without being defined before,
its value is implicitly set to the empty string.
However, defining strings explicitly before use
keeps the code more readable.

.It
expansion of nested escape sequences
including expansion of strings and number registers,
.It
expansion of nested user-defined macros,

.El
When a limit is hit, the output is incorrect, typically losing
some content, but the parser can continue.
.It Sy "skipping bad character"
.Pq mdoc , man , roff
The input file contains a byte that is not a printable
.Xr ascii 7
character.
The message mentions the character number.
The offending byte is replaced with a question mark
.Pq Sq \&? .
Consider editing the input file to replace the byte with an ASCII
transliteration of the intended character.
.It Sy "skipping unknown macro"
.Pq mdoc , man , roff
The first identifier on a request or macro line is neither recognized as a
.Xr roff 7
request, nor as a user-defined macro, nor, respectively, as an
.Xr mdoc 7
or
.Xr man 7
macro.
It may be mistyped or unsupported.
The request or macro is discarded including its arguments.

It is discarded including its arguments.

A
.Ic \&Ta
macro occurs outside any
.Ic \&Bl Fl column

It is discarded including its arguments.
.It Sy "skipping end of block that is not open"
.Pq mdoc , man , eqn , tbl , roff
Various syntax elements can only be used to explicitly close blocks
that have previously been opened.
An
.Xr mdoc 7
block closing macro, a
.Xr man 7
.Ic \&RE
or
.Ic \&UE
macro, or the end of an equation, table, or
.Xr roff 7
conditional request is encountered but no matching block is open.
The offending request or macro is discarded.
.It Sy "inserting missing end of block"
.Pq mdoc , tbl
Various
.Xr mdoc 7
macros as well as tables require explicit closing by dedicated macros.
A block that doesn't support bad nesting
ends before all of its children are properly closed.
The open child nodes are closed implicitly.
.It Sy "scope open on exit"
.Pq mdoc , man , eqn , tbl , roff
At the end of the document, an explicit
.Xr mdoc 7
block, a
.Xr man 7
next-line scope or
.Ic \&RS
or
.Ic \&UR
block, an equation, table, or
.Xr roff 7
conditional or ignore block is still open.
The open block is closed implicitly.
.It Sy "escaped character not allowed in a name"
.Pq roff
Macro, string and register identifiers consist of printable,
non-whitespace ASCII characters.
Escape sequences and characters and strings expressed in terms of them
cannot form part of a name.
The first argument of an
.Ic \&am ,
.Ic \&as ,
.Ic \&de ,
.Ic \&ds ,
.Ic \&nr ,
or
.Ic \&rr
request, or any argument of an
.Ic \&rm
request, or the name of a request or user defined macro being called,
is terminated by an escape sequence.
In the cases of
.Ic \&as ,
.Ic \&ds ,
and
.Ic \&nr ,
the request has no effect at all.
In the cases of
.Ic \&am ,
.Ic \&de ,
.Ic \&rr ,
and
.Ic \&rm ,
what was parsed up to this point is used as the arguments to the request,
and the rest of the input line is discarded including the escape sequence.
When parsing for a request or a user-defined macro name to be called,
only the escape sequence is discarded.
The characters preceding it are used as the request or macro name,
the characters following it are used as the arguments to the request or macro.
.It Sy "argument count wrong"
.Pq mdoc , man , roff
The indicated request or macro has too few or too many arguments.
The syntax tree will contain the wrong number of arguments as given.
Formatting behaviour depends on the specific request or macro in question.
Note that the same message may also occur as a WARNING, see above.
.It Sy "missing list type, using -item"
.Pq mdoc
A
.Ic \&Bl

Currently,

cannot handle input files larger than its arbitrary size limit
of 2^31 bytes (2 Gigabytes).
Since useful manuals are always small, this is not a problem in practice.
Parsing is aborted as soon as the condition is detected.
.It Sy "NOT IMPLEMENTED: Bd -file"
.Pq mdoc
For security reasons, the
.Ic \&Bd
macro does not support the
.Fl file
argument.
By requesting the inclusion of a sensitive file, a malicious document
might otherwise trick a privileged user into inadvertently displaying
the file on the screen, revealing the file content to bystanders.
The parser exits immediately.
.It Sy "NOT IMPLEMENTED: .so with absolute path or \(dq..\(dq"
.Pq roff
For security reasons,
.Nm
allows
.Ic \&so
file inclusion requests only with relative paths
and only without ascending to any parent directory.
By requesting the inclusion of a sensitive file, a malicious document
might otherwise trick a privileged user into inadvertently displaying
the file on the screen, revealing the file content to bystanders.
The parser exits immediately.
.It Sy ".so request failed"
.Pq roff
Servicing a
.Ic \&so
request requires reading an external file.
While trying to do so, an
.Xr open 2 ,
.Xr stat 2 ,

The parser exits immediately.
Before showing this message,
.Nm
always shows another message explaining why the system call failed.

.Sh NAME
.Nm mandoc.db
.Nd manual page database
.Sh DESCRIPTION
The
.Nm
SQLite3 file format is used to store information about installed manual
pages to facilitate semantic searching for manuals.
Each manual page tree contains its own
.Nm
file; see
.Sx FILES
for examples.
.Pp
Such database files are generated by
.Xr makewhatis 8
and used by
.Xr apropos 1
and
.Xr whatis 1 .
.Pp
One line in the following tables describes:
.Bl -tag -width Ds
.It Sy mpages
One physical manual page file, no matter how many times and under which
names it may appear in the file system.
.It Sy mlinks
One entry in the file system, no matter which content it points to.
.It Sy names
One manual page name, no matter whether it appears in a page header,
in a NAME or SYNOPSIS section, or as a file name.
.It Sy keys
One chunk of text from some macro invocation.
.El
.Pp
Each record in the latter three tables uses its
.Va pageid
column to point to a record in the
.Sy mpages
table.
.Pp
The other columns are as follows; unless stated otherwise, they are
of type
.Vt TEXT .
.Bl -tag -width mpages.desc
.It Sy mpages.desc
The description line
.Pq Sq \&Nd
of the page.
.It Sy mpages.form
The
.Vt INTEGER
1 if the page is unformatted, i.e. in
.Xr mdoc 7
or
.Xr man 7
format, and 2 if it is formatted, i.e. a
.Sq cat
page.
.It Sy mlinks.sec
The manual section as found in the subdirectory name.
.It Sy mlinks.arch
The manual architecture as found in the subdirectory name, or
.Qq any .
.It Sy mlinks.name
The manual name as found in the file name.
.It Sy names.bits
An
.Vt INTEGER
bit mask telling whether the name came from a header line, from the
NAME or SYNOPSIS section, or from a file name.
Bits are defined in
.In mansearch.h .
.It Sy names.name
The name itself.
.It Sy keys.bits
An
.Vt INTEGER
bit mask telling which semantic contexts the key was found in;
defined in
.In mansearch.h ,
documented in
.Xr apropos 1 .
.It Sy keys.key
The string found in those contexts.
.El
.Sh FILES
.Bl -tag -width /usr/share/mandoc.db -compact
.It Pa /usr/share/mandoc.db
The manual page database for the base system.
.It Pa /usr/X11R6/mandoc.db
The same for the
.Xr X 7
Window System.
.It Pa /usr/local/mandoc.db
The same for
.Xr packages 7 .
.El
.Sh SEE ALSO
.Xr apropos 1 ,
.Xr man 1 ,
.Xr sqlite3 1 ,
.Xr whatis 1 ,
.Xr mansearch 3 ,
.Xr makewhatis 8
.Sh HISTORY
A manual page database
.Pa /usr/lib/whatis
first appeared in
.Bx 2 .
The present format first appeared in
.Ox 5.6 .
.Sh AUTHORS
.An -nosplit
The original version of
.Xr makewhatis 8
was written by
.An Bill Joy
in 1979.
An SQLite3 version was first implemented by
.An Kristaps Dzonsons Aq Mt kristaps@bsd.lv
in 2012.
The present database format was designed by
.An Ingo Schwarze Aq Mt schwarze@openbsd.org
in 2014.

.Dt MANDOC_ESCAPE 3
.Os
.Sh NAME
.Nm mandoc_escape
.Nd parse roff escape sequences
.Sh LIBRARY
.Lb libmandoc
.Sh SYNOPSIS
.In sys/types.h
.In mandoc.h
.Ft "enum mandoc_esc"
.Fo mandoc_escape
.Fa "const char **end"
.Fa "const char **start"
.Fa "int *sz"
.Fc
.Sh DESCRIPTION
This function scans a
.Xr roff 7
escape sequence.
.Pp
An escape sequence consists of
.Bl -dash -compact -width 2n
.It
an initial backslash 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 -width 2n
.It
recursively by itself, because some escape sequence arguments can
in turn contain other escape sequences,
.It
for error detection internally by the
.Xr roff 7
parser part of the
.Lb libmandoc ,
see the file
.Pa roff.c ,
.It
above all externally by the
.Xr mandoc
formatting modules, in particular
.Fl Tascii
and
.Fl Thtml ,
for formatting purposes, see the 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 argument in standard form:
.Ic \ef[ , \ef( , \ef Ns Ar a .
Two-character arguments starting with the character
.Sq C
are reduced to one-character arguments by skipping the
.Sq C .
More specific values are returned for the most commonly used arguments:
.Bl -column "argument" "ESCAPE_FONTITALIC"
.It argument Ta return value
.It Cm R No or Cm 1 Ta Dv ESCAPE_FONTROMAN
.It Cm I No or Cm 2 Ta Dv ESCAPE_FONTITALIC
.It Cm B No or Cm 3 Ta Dv ESCAPE_FONTBOLD
.It Cm P Ta Dv ESCAPE_FONTPREV
.It Cm BI Ta Dv ESCAPE_FONTBI
.El
.It Dv ESCAPE_SPECIAL
The escape sequence
.Ic \eC
taking an argument delimited with the single quote character
and, as a special exception, the escape sequences
.Em not
having an identifier, that is, those where the argument, in standard
form, directly follows the initial backslash:
.Ic \eC' , \e[ , \e( , \e Ns Ar a .
Note that the one-character argument short form can only be used for
argument characters that do not clash with escape sequence identifiers.
.Pp
If the argument consists of more than one character
and starts with the character
.Sq u ,
.Dv ESCAPE_UNICODE
is returned as described below.
If the argument is just the single character
.Sq u ,
.Dv ESCAPE_ERROR
is returned.
.Pp
The
.Dv ESCAPE_SPECIAL
special character escape sequences can be rendered using the functions
.Fn mchars_spec2cp
and
.Fn mchars_spec2str
described in the
.Xr mchars_alloc 3
manual.
.It Dv ESCAPE_UNICODE
Escape sequences of the same format as described above under
.Dv ESCAPE_SPECIAL ,
but with an argument starting with the character
.Sq u :
.Ic \eC'u , \e[u .
As a special exception,
.Fa start
is set to the character after the
.Sq u ,
and the
.Fa sz
return value does not include the
.Sq u
either.
.Pp
Such Unicode character escape sequences can be rendered using the function
.Fn mchars_num2uc
described in the
.Xr mchars_alloc 3
manual.
.It Dv ESCAPE_NUMBERED
The escape sequence
.Ic \eN
followed by a delimited argument.
The delimiter character is arbitrary except that digits cannot be used.
If a digit is encountered instead of the opening delimiter, that
digit is considered to be the argument and the end of the sequence, and
.Dv ESCAPE_IGNORE
is returned.
.Pp
Such ASCII character escape sequences can be rendered using the function
.Fn mchars_num2char
described in the
.Xr mchars_alloc 3
manual.
.It Dv ESCAPE_IGNORE
.Bl -bullet -width 2n
.It
The escape sequence
.Ic \es
followed by an argument in standard form or by an argument delimited
by the single quote character:
.Ic \es' , \es[ , \es( , \es Ns Ar a .
As a special exception, an optional
.Sq +
or
.Sq \-
character is allowed after the
.Sq s
for all forms.
.It
The escape sequences
.Ic \eF ,
.Ic \eg ,
.Ic \ek ,
.Ic \eM ,
.Ic \em ,
.Ic \en ,
.Ic \eV ,
and
.Ic \eY
followed by an argument in standard form.
.It
The escape sequences
.Ic \eA ,
.Ic \eb ,
.Ic \eD ,
.Ic \eo ,
.Ic \eR ,
.Ic \eX ,
and
.Ic \eZ
followed by an argument delimited by an arbitrary character.
.It
The escape sequences
.Ic \eH ,
.Ic \eh ,
.Ic \eL ,
.Ic \el ,
.Ic \eS ,
.Ic \ev ,
and
.Ic \ex
followed by an argument delimited by a character that cannot occur
in numerical expressions.
However, if any character that can occur in numerical expressions
is found instead of a delimiter, the sequence is considered to end
with that character, and
.Dv ESCAPE_ERROR
is returned.
.El
.It Dv ESCAPE_ERROR
Escape sequences taking an argument but not matching any of the above patterns.
In particular, that happens if the end of the logical input line
is reached before the end of the argument.
.El
.Pp
For sequences that do not take an argument, the function
.Fn mandoc_escape
returns one of the following values:
.Bl -tag -width 2n
.It Dv ESCAPE_SKIPCHAR
The escape sequence
.Qq \ez .
.It Dv ESCAPE_NOSPACE
The escape sequence
.Qq \ec .
.It Dv ESCAPE_IGNORE
The escape sequences
.Qq \ed
and
.Qq \eu .

.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.

.Sh DESCRIPTION
The mandoc HTML formatter is not a formal library.
However, as it is compiled into more than one program, in particular
.Xr mandoc 1
and
.Xr man.cgi 8 ,
and because it may be security-critical in some contexts,
some documentation is useful to help to use it correctly and
to prevent XSS vulnerabilities.
.Pp
The formatter produces HTML output on the standard output.
Since proper escaping is usually required and best taken care of
at one central place, the language-specific formatters
.Po
.Pa *_html.c ,
see
.Sx FILES
.Pc
are not supposed to print directly to
.Dv stdout
using functions like
.Xr printf 3 ,
.Xr putc 3 ,
.Xr puts 3 ,
or
.Xr write 2 .
Instead, they are expected to use the output functions declared in
.Pa html.h
and implemented as part of the main HTML formatting engine in
.Pa html.c .
.Ss Data structures
These structures are declared in
.Pa html.h .
.Bl -tag -width Ds
.It Vt struct html
Internal state of the HTML formatter.
.It Vt struct htmlpair
Holds one HTML attribute.
Members are
.Fa "enum htmlattr key"
and
.Fa "const char *val" .
Helper macros
.Fn PAIR_*
are provided to support initialization of such structures.
.It Vt struct tag
One entry for the LIFO stack of HTML elements.
Members are
.Fa "enum htmltag tag"
and
.Fa "struct tag *next" .
.El
.Ss Private interface functions
The function
.Fn print_gen_decls
prints the opening
.Ao Pf \&? Ic xml ? Ac
and
.Aq Pf \&! Ic DOCTYPE
declarations required for the current document type.
.Pp
The function
.Fn print_gen_head
prints the opening
.Aq Ic META
and
.Aq Ic LINK
elements for the document
.Aq Ic HEAD ,
using the
.Fa style
member of
.Fa h
unless that is
.Dv NULL .
It uses
.Fn print_otag
which takes care of properly encoding attributes,
which is relevant for the
.Fa style
link in particular.
.Pp
The function
.Fn print_otag
prints the start tag of an HTML element with the name
.Fa tag ,
including the
.Fa sz
attributes that can optionally be provided in the
.Fa p
array.
It uses the private function
.Fn print_attr
which in turn uses the private function
.Fn print_encode
to take care of HTML encoding.
If required by the element type, it remembers in
.Fa h
that the element is open.
The function
.Fn print_tagq
is used to close out all open elements up to and including
.Fa until ;
.Fn print_stagq
is a variant to close out all open elements up to but excluding
.Fa suntil .
.Pp
The function
.Fn print_text
prints HTML element content.
It uses the private function
.Fn print_encode
to take care of HTML encoding.
If the document has requested a non-standard font, for example using a
.Xr roff 7
.Ic \ef
font escape sequence,
.Fn print_text
wraps
.Fa word
in an HTML font selection element using the
.Fn print_otag
and
.Fn print_tagq
functions.
.Pp
The functions
.Fn bufinit ,
.Fn bufcat* ,
and
.Fn buffmt*
do not directly produce output but buffer text in the
.Fa buf
member of
.Fa h .
They are not used internally by
.Pa html.c
but intended for use by the language-specific formatters
to ease preparation of strings for the
.Fa p
argument of
.Fn print_otag
and for the
.Fa word
argument of
.Fn print_text .
Consequently, these functions do not do any HTML encoding.
.Pp
The functions
.Fn html_strlen ,
.Fn print_eqn ,
.Fn print_tbl ,
and
.Fn print_tblclose
are not yet documented.

.Sh DESCRIPTION
These functions call the
.Lb libc
functions of the same names, passing through their return values when
successful.
In case of failure, they do not return, but instead call
.Xr perror 3
and
.Xr exit 3 .
They can be used both internally by any code in the
.Lb libmandoc
and externally by programs using that library, for example
.Xr mandoc 1 ,
.Xr apropos 1 ,
and
.Xr makewhatis 8 .
.Pp
The function
.Fn mandoc_malloc
allocates one new object, leaving the memory uninitialized.
The functions
.Fn mandoc_realloc
and
.Fn mandoc_reallocarray
change the size of an existing object or array, possibly moving it.
When shrinking the size, existing data is truncated; when growing,
the additional memory is not initialized.
The function
.Fn mandoc_calloc
allocates a new array, initializing it to zero.
.Pp
The argument
.Fa size
is the size of each object.
The argument
.Fa nmemb
is the new number of objects in the array.
The argument
.Fa ptr
is a pointer to the existing object or array to be resized; if it is
.Dv NULL ,
a new object or array is allocated.
.Pp
The functions
.Fn mandoc_strdup
and
.Fn mandoc_strndup
copy a string into newly allocated memory.
For
.Fn mandoc_strdup ,
the string pointed to by
.Fa s
needs to be NUL-terminated.
For
.Fn mandoc_strndup ,
at most
.Fa maxlen
bytes are copied.
The function
.Fn mandoc_asprintf
writes output formatted according to
.Fa format
into newly allocated memory and returns a pointer to the result in
.Fa ret .
For all three string functions, the result is always NUL-terminated.
.Pp
When the objects and strings are no longer needed,
the pointers returned by these functions can be passed to
.Xr free 3 .
.Sh RETURN VALUES
The function
.Fn mandoc_asprintf
always returns the number of characters written, excluding the
final NUL byte.
It never returns -1.
.Pp
The other functions always return a valid pointer; they never return
.Dv NULL .
.Sh FILES
These functions are implemented in
.Pa mandoc_aux.c .
.Sh SEE ALSO
.Xr asprintf 3 ,
.Xr exit 3 ,
.Xr malloc 3 ,
.Xr perror 3 ,
.Xr strdup 3
.Sh STANDARDS
The functions
.Fn malloc ,
.Fn realloc ,
and
.Fn calloc
are required by
.St -ansiC .
The functions
.Fn strdup
and
.Fn strndup
are required by
.St -p1003.1-2008 .
The function
.Fn asprintf
is a widespread extension that first appeared in the GNU C library.
.Pp
The function
.Fn reallocarray
is an extension that first appeared in
.Ox 5.6 .
If it is not provided by the operating system, the mandoc build system
uses a bundled portable implementation.
.Sh HISTORY
The functions
.Fn mandoc_malloc ,
.Fn mandoc_realloc ,
.Fn mandoc_calloc ,
and
.Fn mandoc_strdup
have been available since mandoc 1.9.12,
.Fn mandoc_strndup
since 1.11.5,
and
.Fn mandoc_asprintf
and
.Fn mandoc_reallocarray
since 1.12.4 and 1.13.0.

.Sh NAME
.Nm mansearch ,
.Nm mansearch_setup
.Nd search manual page databases
.Sh SYNOPSIS
.In stdint.h
.In manpath.h
.In mansearch.h
.Ft int
.Fo mansearch_setup
.Fa "int start"
.Fc
.Ft int
.Fo mansearch
.Fa "const struct mansearch *search"
.Fa "const struct manpaths *paths"
.Fa "int argc"
.Fa "char *argv[]"
.Fa "const char *outkey"
.Fa "struct manpage **res"
.Fa "size_t *sz"
.Fc
.Sh DESCRIPTION
The
.Fn mansearch
function returns information about manuals matching a search query from a
.Xr mandoc.db 5
SQLite3 database.
.Pp
The query arguments are as follows:
.Bl -tag -width Ds
.It Fa "const struct mansearch *search"
Search options, defined in
.In mansearch.h .
.It Fa "const struct manpaths *paths"
Directories to be searched, defined in
.In manpath.h .
.It Fa "int argc" , "char *argv[]"
Search criteria, usually taken from the command line.
.El
.Pp
The
.Fa "const char *outkey"
selects which data to return in the
.Va output
field of the
.Fa res
structures.
It takes any of the macro keys defined in
.Pa mansearch_const.c
and described in
.Xr apropos 1 .
.Pp
The output arguments are as follows:
.Bl -tag -width Ds
.It Fa "struct manpage **res"
Returns a pointer to an array of result structures defined in
.In mansearch.h .
The user is expected to call
.Xr free 3
on the
.Va file ,
.Va names ,
and
.Va output
fields of all structures, as well as the
.Fa res
array itself.
.It Fa "size_t *sz"
Returns the number of result structures contained in
.Fa res .
.El
.Pp
To speed up searches, the
.Fn mansearch_setup
function can optionally be called with a
.Fa start
argument of 1 before
.Fn mansearch
to set up an SQLite3 pagecache.
If it was called, it has to be called again with a
.Fa start
argument of 0 after the last call to
.Fn mansearch
to release the memory used for the pagecache.
.Sh IMPLEMENTATION NOTES
For each manual page tree, the search is done in two steps.
In the first step, a list of pages matching the search criteria is built.
In the second step, the requested information about these pages is
retrieved from the database and assembled into the
.Fa res
array.
.Pp
All function mentioned here are defined in the file
.Pa mansearch.c .
No functions except
.Fn mansearch
and
.Fn sql_statement
build any SQL code, and no functions except
.Fn mansearch ,
.Fn buildnames ,
and
.Fn buildoutput
execute it.
.Ss Finding matches
The query is built using the following grammar:
.Bd -literal -offset indent
<query> ::= "SELECT * FROM mpages WHERE" <condition>
<condition> ::= "(" <condition> ")" |
<condition> "OR" <condition> |
<condition> "AND" <condition> |
"desc" <operator> "?" |
"id IN (SELECT pageid FROM" <subquery> ")"
<subquery> ::= "names WHERE name" <operator> "?" |
"keys WHERE key" <operator> "? AND bits & ?"
<operator> ::= "MATCH" | "REGEXP"
.Ed
.Pp
The MATCH and REGEXP operators are implemented by the functions
.Fn sql_match
and
.Fn sql_regexp ,
respectively.
This is required because SQLite3 natively neither supports
case-insensitive substring matching nor regular expression matching,
but only string identity, shell globbing, and the weird home-brewed
LIKE operator.
.Pp
Command line parsing is done by the function
.Fn exprcomp
building a singly linked list of
.Vt expr
structures, using the helper functions
.Fn exprterm
and
.Fn exprspec .
The resulting SQL statement is assembled by the function
.Fn sql_statement
and evaluated in the main loop of the
.Fn mansearch
function.
.Ss Assembling the results
The names, sections, and architectures of the manuals found
are assembled into the
.Va names
field of the result structure by the function
.Fn buildnames ,
using the following query:
.Pp
.Dl "SELECT * FROM mlinks WHERE pageid=? ORDER BY sec, arch, name"
.Pp
If the
.Fa outkey
differs from
.Qq Nd ,
the requested output data is assembled into the
.Va output
field of the result structure by the function
.Fn buildoutput ,
using the following query:
.Pp
.Dl "SELECT * FROM keys WHERE pageid=? AND bits & ?"
.Sh FILES
.Bl -tag -width mandoc.db -compact
.It Pa mandoc.db
The manual page database.
.El
.Sh EXAMPLES
The simplest invocation
.Pp
.Dl apropos keyword
.Pp
results in the following SQL query:
.Bd -literal
SELECT * FROM mpages WHERE (
id IN (SELECT pageid FROM names WHERE name MATCH 'keyword') OR
desc MATCH 'keyword'
);
.Ed
.Pp
A more complicated request like
.Pp
.Dl apropos -s 2 Nm,Xr=getuid
.Pp
results in:
.Bd -literal
SELECT * FROM mpages WHERE (
id IN (SELECT pageid FROM names WHERE name MATCH 'getuid') OR
id IN (SELECT pageid FROM keys WHERE key MATCH 'getuid' AND bits & 4)
) AND id IN (SELECT pageid FROM keys WHERE key REGEXP '^2$' AND bits & 2);

.Sh DESCRIPTION
These functions translate Unicode character numbers and
.Xr roff 7
character 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
allocates an opaque
.Vt "struct mchars *"
table 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 in the
.Fa table
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 in the
.Fa table
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.

These funtions are implemented in the file
.Pa chars.c .

* Flush a line of text. A "line" is loosely defined as being something
* that should be followed by a newline, regardless of whether it's
* broken apart by newlines getting there. A line can also be a
* fragment of a columnar list (`Bl -tag' or `Bl -column'), which does
* not have a trailing newline.
*
* Flush a chunk of text. By default, break the output line each time
* the right margin is reached, and continue output on the next line
* at the same offset as the chunk itself. By default, also break the
* output line at the end of the chunk.
* The following flags may be specified:
*
* - TERMP_NOBREAK: this is the most important and is used when making
* columns. In short: don't print a newline and instead expect the
* next call to do the padding up to the start of the next column.
* p->trailspace may be set to 0, 1, or 2, depending on how many
* space characters are required at the end of the column.
*
* - TERMP_DANGLE: don't newline when TERMP_NOBREAK is specified and
* the line is overrun, and don't pad-right if it's underrun.
*
* - TERMP_HANG: like TERMP_DANGLE, but doesn't newline when
* overrunning, instead save the position and continue at that point
* when the next invocation.
*
* In-line line breaking:
*
* If TERMP_NOBREAK is specified and the line overruns the right
* margin, it will break and pad-right to the right margin after
* writing. If maxrmargin is violated, it will break and continue
* writing from the right-margin, which will lead to the above scenario
* upon exit. Otherwise, the line will break at the right margin.
* - TERMP_NOBREAK: Do not break the output line at the right margin,
* but only at the max right margin. Also, do not break the output
* line at the end of the chunk, such that the next call can pad to
* the next column. However, if less than p->trailspace blanks,
* which can be 0, 1, or 2, remain to the right margin, the line
* will be broken.
* - TERMP_BRIND: If the chunk does not fit and the output line has
* to be broken, start the next line at the right margin instead
* of at the offset. Used together with TERMP_NOBREAK for the tags
* in various kinds of tagged lists.
* - TERMP_DANGLE: Do not break the output line at the right margin,
* append the next chunk after it even if this one is too long.
* To be used together with TERMP_NOBREAK.
* - TERMP_HANG: Like TERMP_DANGLE, and also suppress padding before
* the next chunk if this column is not full.
