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.

Changes in version 1.12.3, released on December 31, 2013
* In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
Thanks to Franco Fichtner for doing part of the work.
* The mdoc(7) .Bk macro got some addititonal bugfixes.
* In mdoc(7) macro arguments, double quotes can now be quoted
by doubling them, just like in man(7).
Thanks to Tsugutomo ENAMI for the patch.
* At the end of man(7) macro lines, end-of-sentence spacing
now works. Thanks to Franco Fichtner for the patch.
* For backward compatibility, the man(7) parser now supports the
man-ext .UR/.UE (uniform resource identifier) block macros.
* The man(7) parser now handles closing blocks that are not open
more gracefully.
* The man(7) parser now ignores blank lines right after .SH and .SS.
* In the man(7) formatter, reset indentation when leaving a block,
not just when entering the next one.
* The roff(7) .nr request now supports incrementing and decrementing
number registers and stops parsing the number right before the
first non-digit character.
* The roff(7) parser now supports the alternative escape sequence
syntax \C'uXXXX' for Unicode characters.
* The roff(7) parser now parses and ignores the .fam (font family)
and .hw (hyphenation points) requests and the \d and \u escape
sequences.
* The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
Changes in version 1.12.2, released on Oktober 5, 2013
* The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
is now fully functional.
* The mandoc(1) utility now supports the -Ios (default operating system)
input option, and the -Tutf8 output mode now actually works.
* The mandocdb(8) utility no longer truncates existing databases when
starting to build new ones, but only replaces them when the build
actually succeeds.
* The man(7) parser now supports the PD macro (paragraph distance),
and (for GNU man-ext compatibility only) EX (example block) and EE
(example end). Plus several bugfixes regarding indentation, line
breaks, and vertical spacing, and regarding RS following TP.
* The roff(7) parser now supports the \f(BI (bold+italic) font escape,
the \z (zero cursor advance) escape and the cc (change control
character) and it (input line trap) requests. Plus bugfixes regarding
the \t (tab) escape, nested escape sequences, and conditional requests.
* In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
enclosures, delimiter handling, list indentation and horizontal and
vertical spacing, formatting of the Lk, %U, and %C macros, plus some
bugfixes related to the handling of syntax errors like badly nested
font blocks, stray Ta macros outside column lists, unterminated It Xo
blocks, and non-text children of Nm blocks.
* In tbl(7), the width of horizontal spans and the vertical spacing
around tables was corrected, and in man(7) files, a crash was fixed
that was triggered by some particular unclosed T{ macros.
* For mandoc developers, we now provide a tbl(3) library manual and
gmdiff, a very small, very simplistic groff-versus-mandoc output
comparison tool.
* Provide this NEWS file.
Changes in version 1.12.1, released on March 23, 2012
* Significant work on apropos(1) and mandocdb(8). These tools are now
much more robust. A whatis(1) implementation is now handled as an
apropos(1) mode. These tools are also able to minimally handle
pre-formatted pages, that is, those already formatted by another
utility such as GNU troff.
* The man.cgi(7) script is also now available for wider testing.
It interfaces with mandocdb(8) manuals cached by catman(8).
HTML output is generated on-the-fly by libmandoc or internal
methods to convert pre-formatted pages.
* The mailing list archive for the discuss and tech lists are being
hosted by Gmane at gmane.comp.tools.mdocml.user and
gmane.comp.tools.mdocml.devel, respectively.
Changes in version 1.12.0, released on October 8, 2011
* This version features a new, work-in-progress mandoc(1) output mode:
-Tman. This mode allows a system maintainer to distribute man(7)
media for older systems that may not natively support mdoc(7), such
as old Solaris systems.
* The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
* While adding features, an apropos(1) utility has been merged from the
mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
search of manual content. apropos(1) is different from the traditional
apropos primarily in allowing keyword search (such as for functions,
utilities, etc.) and regular expressions. Note that the calling
syntax for apropos is likely to change as it settles down.
* In documentation news, the mdoc(7) and man(7) manuals have been
made considerably more readable by adding MACRO OVERVIEW sections, by
moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
and by moving the very technical MACRO SYNTAX sections down to the
bottom of the page.
* Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
was rewritten completely. It is now compatible with groff(1), both
with and without frames and rulers.
* Nesting of indented blocks is now supported in man(7), and several
bugs were fixed regarding indentation and alignment.
* The page headers in mdoc(7) are now nicer for very long titles.
Changes in version 1.11.7, released on September 2, 2011
* Added demandoc(1) utility for stripping away macros and escapes.
This replaces the historical deroff(1) utility.
* Also improved the mdoc(7) and man(7) manuals.
Changes in version 1.11.6, released on August 16, 2011
* Handling of tr macro in roff(7) implemented. This makes Perl
documentation much more readable. Hyphenation is also now enabled in
man(7) format documents. Many other general improvements have been
implemented.
Changes in version 1.11.5, released on July 24, 2011
* Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
input (although few GNU extensions are accepted, nor is mixing
low-level roff with eqn). See the eqn(7) manual for details.
For the time being, equations are rendered as simple in-line text.
The equation parser satisfies the language specified in the
Second Edition User's Guide:
http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
Changes in version 1.11.4, released on July 12, 2011
* Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
and the man(7) parser. This release was significantly assisted by
participants in OpenBSD's c2k11. Thanks!
Changes in version 1.11.3, released on May 26, 2011
* Introduce locale-encoding of output with the -Tlocale output option and
Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
respectively, for details. This allows for non-ASCII characters (e.g.,
\[u5000]) to be rendered in the locale's encoding, if said environment
supports wide-character encoding (if it does not, -Tascii is used
instead). Locale support can be turned off at compile time by removing
-DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
for -Tascii.
* Furthermore, multibyte-encoded documents, such as those in UTF-8, may
be on-the-fly recoded into mandoc(1) input by using the newly-added
preconv(1) utility. Note: in the future, this feature may be
integrated into mandoc(1).
Changes in version 1.11.2, released on May 12, 2011
* Corrected some installation issues in version 1.11.1.
* Further migration to libmandoc.
* Initial public release (this utility is very much under development)
of mandocdb(8). This utility produces keyword databases of manual
content, which features semantic querying of manual content.
Changes in version 1.11.1, released on April 4, 2011
* The earlier libroff, libmdoc, and libman soup have been merged into
a single library, libmandoc, which manages all aspects of parsing
real manuals, from line-handling to tbl(7) parsing.
* As usual, many general fixes and improvements have also occurred.
In particular, a great deal of redundancy and superfluous code has
been removed with the merging of the backend libraries.
* see also the changes in 1.10.10
Changes in version 1.10.10, March 20, 2011, NOT released
* Initial eqn(7) functionality is in place. For the time being,
this is limited to the recognition of equation blocks;
future version of mdocml will expand upon this framework.
Changes in version 1.10.9, released on January 7, 2011
* Many back-end fixes have been implemented: argument handling (quoting),
man(7) improvements, error/warning classes, and many more.
* Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
minimal, especially for -Thtml and -Txhtml, but manages to at least
display data. This means that mandoc(1) now has built-in support
for two troff preprocessors via libroff: soelim(1) and tbl(1).
Changes in version 1.10.8, released on December 24, 2010
* Overhauled the -Thtml and -Txhtml output modes. They now display
readable output in arbitrary browsers, including text-based ones like
lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
for examples. Attention: available style-sheet classes have been
considerably changed! See the example.style.css file for details.
Lastly, libmdoc and libman have been cleaned up and reduced in size
and complexity.
* see also the changes in 1.10.7
Changes in version 1.10.7, December 6, 2010, NOT released
Significant improvements merged from OpenBSD downstream, including:
* many new roff(7) components,
* in-line implementation of troff's soelim(1),
* broken-block handling,
* overhauled error classifications, and
* cleaned up handling of error conditions.
Changes in version 1.10.6, released on September 27, 2010
* Calling conventions for mandoc(1) have changed: -W improved and -f
deprecated.
* Non-ASCII characters are also now uniformly discarded.
* Lots of documentation improvements.
* Many incremental fixes accomodating for groff's more interesting
productions.
* Lastly, pod2man(1) preambles are now fully accepted after some
considerable roff(7) and special character support.
Changes in version 1.10.5, released on July 27, 2010
* Primarily a bug-fix and polish release, but including -Tpdf support
in mandoc(1) by way of "Summer of Code". Highlights:
* fix "Sm" and "Bd" handling
* fix end-of-sentence handling for embedded sentences
* polish man(7) documentation
* document all mdoc(7) macros
* polish mandoc(1) -Tps output
* lots of internal clean-ups in character escapes
* un-break literal contexts in man(7) documents
* improve -Thtml output for -man
* add mandoc(1) -Tpdf support
Changes in version 1.10.4, released on July 12, 2010
* Lots of features developed during both "Summer of Code" and the
OpenBSD c2k10 hackathon:
* minimal "ds" roff(7) symbols are supported
* beautified SYNOPSIS section output
* acceptance of scope-block breakage in mdoc(7)
* clarify error message status
* many minor bug-fixes and formatting issues resolved
* see also changes in 1.10.3
Changes in version 1.10.3, June 29, 2010, NOT released
* variable font-width and paper-size support in mandoc(1) -Tps output
* "Bk" mdoc(7) support
Changes in version 1.10.2, released on June 19, 2010
* Small release featuring text-decoration in -Tps output,
a few minor relaxations of errors, and some optimisations.
Changes in version 1.10.1, released on June 7, 2010
* This primarily focusses on the "Bl" and "It" macros described in
mdoc(7). Multi-line column support is now fully compatible with groff,
as are implicit list entries for columns.
* Removed manuals(7) in favour of http://manpages.bsd.lv.
* The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
in MANUAL STRUCTURE) has also been considerably simplified compared
to groff's method.
* Furthermore, the -Owidth=width output option has been added to -Tascii,
see mandoc(1).
* Lastly, initial PostScript output has been added with the -Tps option
to mandoc(1). It's brutally simple at the moment: fixed-font, with no
font decorations.
Changes in version 1.10.0, released on May 29, 2010
* Release consisting of the results from the m2k10 hackathon and up-merge
from OpenBSD. This requires a significant note of thanks to Ingo
Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
Ingo's m2k10 report) follow in no particular order:
* a libroff preprocessor in front of libmdoc and libman stripping out
roff(7) instructions;
* end-of-sentence (EOS) detection in free-form and macro lines;
* correct handling of tab-separated columnar lists in mdoc(7);
* improved main calling routines to optionally use mmap(3) for better
performance;
* cleaned up exiting when invoked as -Tlint or over multiple files
with -fign-errors;
* error and warning message handling re-written to be unified for
libroff, libmdoc, and libman;
* handling of badly-nested explicit-scoped macros;
* improved free-form text parsing in libman and libmdoc;
* significant GNU troff compatibility improvements in -Tascii,
largely in terms of spacing;
* a regression framework for making sure the many fragilities of GNU
troff aren't trampled in subsequent work;
* support for -Tascii breaking at hyphens encountered in free-form text;
* and many more minor fixes and improvements
Changes in version 1.9.25, released on May 13, 2010
* Fixed handling of "\*(Ba" escape.
* Backed out -fno-ign-chars (pointless complexity).
* Fixed erroneous breaking of literal lines.
* Fixed SYNOPSIS breaking lines before non-initial macros.
* Changed default section ordering.
* Most importantly, the framework for end-of-sentence double-spacing is
in place, now implemented for the "end-of-sentence, end-of-line" rule.
* This is a stable roll-back point before the mandoc hackathon in Rostock!
Changes in version 1.9.24, released on May 9, 2010
* Rolled back break-at-hyphen.
* -DUGLY is now the default (no feature splits!).
* Free-form text is not de-chunked any more: lines are passed
whole-sale into the front-end, including whitespace.
* Added mailing lists.
Changes in version 1.9.23, released on April 7, 2010
* mdocml has been linked to the OpenBSD build.
* This version incorporates many small changes, mostly from patches
by OpenBSD, allowing crufty manuals to slip by with warnings instead
of erroring-out.
* Some subtle semantic issues, such as punctuation scope, have also
been fixed.
* Lastly, some issues with -Thtml have been fixed, which prompted an
update to the online manual pages style layout.
Changes in version 1.9.22, released on March 31, 2010
* Adjusted merge of the significant work by Ingo Schwarze
in getting "Xo" blocks (block full implicit, e.g., "It"
for non-columnar lists) to work properly. This isn't
enabled by default: you must specify -DUGLY as a compiler
flag (see the Makefile for details).
Changes in version 1.9.20, released on March 30, 2010
* More efforts to get roff instructions in man(7) documents under
control. Note that roff instructions embedded in line-scoped,
next-line macros (e.g. "B") are not supported.
* Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
are now correctly handled.
Changes in version 1.9.18, released on March 27, 2010
* Many fixes (largely pertaining to scope)
and improvements (e.g., handling of apostrophe-control macros,
which fixes the strange "BR" seen in some macro output)
to handling roff instructions in man(7) documents.
Changes in version 1.9.17, released on March 25, 2010
* Accept perlpod(1) standard preamble.
* Also accept (and discard) "de", "dei", "am", "ami", and "ig"
roff macro blocks.
Changes in version 1.9.16, released on March 22, 2010
* Inspired by patches and bug reports by Ingo Schwarze,
allowed man(7) to accept non-printing elements to be nested
within next-line scopes, such as "br" within "B" or "TH",
which is valid roff.
* Longsoon architecture also noted and Makefile cleaned up.
Changes in version 1.9.15, released on February 18, 2010
* Moved to our new BSD.lv home.
* XHTML is now an acceptable output mode for mandoc(1);
* "Xr" made more compatible with groff;
* "Vt" fixed when invoked in SYNOPSIS;
* "\\" escape removed;
* end-of-line white-space detected for all lines;
* subtle bug fixed in list display for some modes;
* compatibility layer checked in for compilation in diverse
UNIX systems;
* and column lengths handled correctly.
