This file lists the most important changes in the mdocml.bsd.lv distribution.
This file lists the most important changes in the mandoc.bsd.lv distribution.
Changes in version 1.14.2, released on July 28, 2017
--- MAJOR NEW FEATURES ---
* New mdoc(7) -Tmarkdown output mode.
* For -Thtml, implement internal hyperlinks pointing to authoritative
definitions of various syntax elements, similar to the ctags(1)-like
less(1) :t internal searching in terminal mode.
* Provide a superset of the functionality of the former mdoclint(1)
utility and a new -Wstyle message level with several new messages,
including validity checking of .Xr cross references.
* tbl(7): Implement automatic line breaking inside individual table
cells, and several other formatting improvements.
* eqn(7): Complete rewrite of the lexer, resulting in several bugfixes.
* Continue parser unification, in particular allowing generation
of syntax tree nodes on the roff(7) level, allowing implementation
of many additional roff requests.
--- REMOVED FUNCTIONALITY ---
* Delete the manpage(1) utility. It was never enabled in any release.
* Delete the -Txhtml command line option. It has been an obsolete
alias for the -Thtml output mode for more than two years.
--- MINOR NEW FEATURES ---
* -Tlint now puts parser messages on stdout instead of stderr,
making commands like "man -l -Tlint *.1" useful.
* mdoc(7): Various .Lk formatting improvements.
* mdoc(7) -Thtml: Better CSS for .Bl lists.
* man(7): Implement the .MT/.ME block macro (mailto hyperlink).
* man(7): Implement the .DT macro (restore default tab positions).
* man(7): Improved support for manuals generated with reStructuredText
by partial support for the \n[an-margin] number register.
* man(7) -Thtml: Support deep linking to .SH and .SS headers.
* tbl(7): Implement the "allbox" table option.
* tbl(7): Implement the column spacing and the 'w' (minimum column
width) layout modifiers.
* tbl(7): Significant improvements of the manual page.
* eqn(7): Much improved font selection, including recognition of
well-known function names, and a few other formatting improvements.
* eqn(7) -Thtml: Use <mn> and <mo> in addition to <mi>.
* roff(7): Implement the .ce (centering), .mc (margin character),
.rj (right justify), .ta (define tab stops), .ti (temporary indent),
.als (macro alias), .ec and .eo (escape character control),
.po (page offset), and .rn (macro rename) requests.
* roff(7) .am: Implement appending to mdoc(7) and man(7) macros.
* roff(7): implement the \h (horizontol motion), \l (horizontal
line drawing), and \p (break output line) escape sequences,
and also several additional character escape sequences.
* roff(7): Implement the 'd' conditional (macro or string defined).
* man.cgi(8) now uses pledge(2), too.
* regress.pl(1): simpler user interface, better summary output,
simpler code, and no more recursion.
--- THANKS TO ---
* Anthony Bentley (OpenBSD) for the implementation of .MT/.ME,
reports of many bugs and missing features, and suggestions
for a number of feature and documentation improvements.
* Sebastien Marie (OpenBSD) for two source code patches and
for some useful discussions.
* Florian Obser (OpenBSD) for a bugfix patch and a bug report.
* Jonathan Gray (OpenBSD) for several bug reports from afl(1)
and several more from static analysis tools.
* Theo Buehler (OpenBSD) for several bug reports, most from afl(1).
* Jason McIntyre (OpenBSD) for many useful discussions about a
wide variety of topics, lots of continuous testing, a number of
bug reports, and some suggestions for messages and documentation.
* Thomas Klausner (NetBSD) for lots of help while migrating
mdoclint(1) functionality to mandoc -Tlint, for suggesting
several useful new messages, and for release testing.
* Reyk Floeter (OpenBSD) and Vsevolod Stakhov (FreeBSD) for
suggesting a markdown output mode.
* Thomas Guettler for suggesting -Thtml internal hyperlinks.
* Yuri Pankov (Illumos) for inspiring new warning messages and
for extensive release testing.
* Anton Lindqvist and TJ Townsend (both OpenBSD) and Jan Stary
for multiple bug reports.
* Leah Neukirchen (Void Linux) for bug reports and release testing.
* Michael Stapelberg (Debian) for suggesting feature improvements
and for release testing.
* Martin Natano and Theo de Raadt (both OpenBSD), Andreas Voegele,
Gabriel Guzman, Gonzalo Tornaria, Markus Waldeck, and Raf Czlonka
for bug reports.
* Antoine Jacoutot (OpenBSD) and Steffen Nurpmeso for suggesting
feature improvements.
* Dag-Erling Smoergrav (FreeBSD) for inspiring new warning messages.
* Ted Unangst and Marc Espie (OpenBSD) for providing useful ideas.
* Svyatoslav Mishyn (Crux Linux) for release testing.
* Carsten Kunze (Heirloom roff) for help keeping mandoc and groff
compatible and for committing some of my patches to groff.

- GNU eqn converts some operators to special characters, for example,
input HYPHEN-MINUS becomes output \(mi, unless it is part of a
quoted word. mandoc(1) only does this when the operator is
surrounded by blanks, not when it is part of an unquoted word.
Also, check whether there are more such cases (e.g., +?).

This manual describes the subset of the
.Nm
language accepted by the
.Xr mandoc 1
utility.
.Pp
Tables within
.Xr mdoc 7
or
.Xr man 7
are enclosed by the
.Sq TS
and
.Sq TE
macro tags, whose precise syntax is documented in
.Xr roff 7 .
Tables consist of a series of options on a single line, followed by the
table layout, followed by data.
.Pp
For example, the following creates a boxed table with digits centered in
the cells.
.Bd -literal -offset indent
\&.TS
tab(:) box;
c5 c5 c5.

Table data is

that is, data rows are parsed then inserted into the underlying stream
of input data.
This allows data rows to be interspersed by arbitrary

Layout specifies how data rows are displayed on output.
Each layout line corresponds to a line of data; the last layout line

Layout lines may also be separated by a comma.
Each layout cell consists of one of the following case-insensitive keys:

a single or double horizontal line is drawn across the cell,
joining its neighbours.
If a data cells contains only the two character sequence
.Ql \e_
or
.Cm \e=
is specified, a line is drawn within the data field (i.e. terminating
within the cell and not draw to the border).
If the last cell of a line is
.Cm T{ ,
all subsequent lines are included as part of the cell until
.Cm T}
is specified as its own data cell.
It may then be followed by a tab
.Pq or as designated by Cm tab
or an end-of-line to terminate the row.
.Ql \e= ,
a single or double horizontal line is drawn inside the cell,
not joining its neighbours.
If a data line contains nothing but the single character
.Ql _
or
.Ql = ,
a horizontal line across the whole table is inserted
without consuming a layout row.
.Pp
In place of any data cell, a text block can be used.
It starts with
.Ic \&T{
at the end of a physical input line.
Input line breaks inside the text block
neither end the text block nor its data cell.
It only ends if
.Ic \&T}
occurs at the beginning of a physical input line and is followed
by an end-of-cell indicator.
If the
.Ic \&T}
is followed by the end of the physical input line, the text block,
the data cell, and the data line ends at this point.
If the
.Ic \&T}
is followed by the
.Cm tab
character, only the text block and the data cell end,
but the data line continues with the data cell following the
.Cm tab
character.
If
.Ic \&T}
is followed by any other character, it does not end the text block,
which instead continues to the following physical input line.
