547: The mandoc(1) manual now includes a list explaining all messages.
548: --- MINOR NEW FEATURES ---
549: * The roff(7) parser now supports the .ami (append to macro with

571: supported by the .St macro are related to each other.
572: --- BUGFIXES ---
573: * In the roff(7) parser, several bugs were fixed with respect
574: to closing conditional blocks on macro lines.
575: * Parsing of roff(7) identifiers and escape sequences was improved
576: in multiple respects.
577: * In the mdoc(7) parser, the handling of defective document
578: prologues was improved in multiple ways.
579: * The mdoc(7) parser no longer skips content before the first section
580: header, and it no longer deletes non-.% content from .Rs blocks.
581: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
582: * In the mdoc(7) parser, handling of .Sm with missing or invalid

584: * In the mdoc(7) parser, trailing punctuation at the end of partial
585: implicit macros no longer triggers end-of-sentence spacing.
586: * In the terminal formatter, two crashes were fixed: one triggered by
587: excessive indentation and another by excessively long .Nm arguments.
588: * In the terminal formatter, a floating point rounding bug was
589: fixed that sometimes caused an off-by-one error in indentation.
590: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
591: and non-breakable spaces was corrected.
592: * In the HTML formatter, encoding of special characters was
593: corrected in multiple respects.
594: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
595: improved for various edge cases.
596: * In the mdoc(7) formatter, handling of empty .Bl -inset item
597: heads was improved.
598: * In the man(7) formatter, some bugs were fixed with respect
599: to same-line detection in the context of .TP and .nf macros,
600: and the indentation of .IP and .TP blocks was improved.
601: * The mandoc(3) library no longer prints to stderr.

615: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
616: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
617: Thanks to Franco Fichtner for doing part of the work.
618: * The mdoc(7) .Bk macro got some addititonal bugfixes.
619: * In mdoc(7) macro arguments, double quotes can now be quoted
620: by doubling them, just like in man(7).
621: Thanks to Tsugutomo ENAMI for the patch.
622: * At the end of man(7) macro lines, end-of-sentence spacing
623: now works. Thanks to Franco Fichtner for the patch.
624: * For backward compatibility, the man(7) parser now supports the
625: man-ext .UR/.UE (uniform resource identifier) block macros.
626: * The man(7) parser now handles closing blocks that are not open
627: more gracefully.
628: * The man(7) parser now ignores blank lines right after .SH and .SS.
629: * In the man(7) formatter, reset indentation when leaving a block,
630: not just when entering the next one.
631: * The roff(7) .nr request now supports incrementing and decrementing
632: number registers and stops parsing the number right before the
633: first non-digit character.
634: * The roff(7) parser now supports the alternative escape sequence
635: syntax \C'uXXXX' for Unicode characters.
636: * The roff(7) parser now parses and ignores the .fam (font family)
637: and .hw (hyphenation points) requests and the \d and \u escape
638: sequences.

1.1 schwarze 640:
1.2 schwarze 641: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 642:
643: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
644: is now fully functional.
645: * The mandoc(1) utility now supports the -Ios (default operating system)
646: input option, and the -Tutf8 output mode now actually works.
647: * The mandocdb(8) utility no longer truncates existing databases when
648: starting to build new ones, but only replaces them when the build
649: actually succeeds.
650: * The man(7) parser now supports the PD macro (paragraph distance),
651: and (for GNU man-ext compatibility only) EX (example block) and EE
652: (example end). Plus several bugfixes regarding indentation, line
653: breaks, and vertical spacing, and regarding RS following TP.
654: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
655: the \z (zero cursor advance) escape and the cc (change control
656: character) and it (input line trap) requests. Plus bugfixes regarding
657: the \t (tab) escape, nested escape sequences, and conditional requests.
658: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
659: enclosures, delimiter handling, list indentation and horizontal and
660: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
661: bugfixes related to the handling of syntax errors like badly nested
662: font blocks, stray Ta macros outside column lists, unterminated It Xo
663: blocks, and non-text children of Nm blocks.
664: * In tbl(7), the width of horizontal spans and the vertical spacing
665: around tables was corrected, and in man(7) files, a crash was fixed
666: that was triggered by some particular unclosed T{ macros.
667: * For mandoc developers, we now provide a tbl(3) library manual and
668: gmdiff, a very small, very simplistic groff-versus-mandoc output
669: comparison tool.
1.2 schwarze 670: * Provide this NEWS file.
1.1 schwarze 671:
672: Changes in version 1.12.1, released on March 23, 2012
673:
674: * Significant work on apropos(1) and mandocdb(8). These tools are now
675: much more robust. A whatis(1) implementation is now handled as an
676: apropos(1) mode. These tools are also able to minimally handle
677: pre-formatted pages, that is, those already formatted by another
678: utility such as GNU troff.
679: * The man.cgi(7) script is also now available for wider testing.
680: It interfaces with mandocdb(8) manuals cached by catman(8).
681: HTML output is generated on-the-fly by libmandoc or internal
682: methods to convert pre-formatted pages.
683: * The mailing list archive for the discuss and tech lists are being
684: hosted by Gmane at gmane.comp.tools.mdocml.user and
685: gmane.comp.tools.mdocml.devel, respectively.
686:
687: Changes in version 1.12.0, released on October 8, 2011
688:
689: * This version features a new, work-in-progress mandoc(1) output mode:
690: -Tman. This mode allows a system maintainer to distribute man(7)
691: media for older systems that may not natively support mdoc(7), such
692: as old Solaris systems.
693: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
694: * While adding features, an apropos(1) utility has been merged from the
695: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
696: search of manual content. apropos(1) is different from the traditional
697: apropos primarily in allowing keyword search (such as for functions,
698: utilities, etc.) and regular expressions. Note that the calling
699: syntax for apropos is likely to change as it settles down.
700: * In documentation news, the mdoc(7) and man(7) manuals have been
701: made considerably more readable by adding MACRO OVERVIEW sections, by
702: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
703: and by moving the very technical MACRO SYNTAX sections down to the
704: bottom of the page.
705: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
706: was rewritten completely. It is now compatible with groff(1), both
707: with and without frames and rulers.
708: * Nesting of indented blocks is now supported in man(7), and several
709: bugs were fixed regarding indentation and alignment.
710: * The page headers in mdoc(7) are now nicer for very long titles.
711:
712: Changes in version 1.11.7, released on September 2, 2011
713:
714: * Added demandoc(1) utility for stripping away macros and escapes.
715: This replaces the historical deroff(1) utility.
716: * Also improved the mdoc(7) and man(7) manuals.
717:
718: Changes in version 1.11.6, released on August 16, 2011
719:
720: * Handling of tr macro in roff(7) implemented. This makes Perl
721: documentation much more readable. Hyphenation is also now enabled in
722: man(7) format documents. Many other general improvements have been
723: implemented.
724:
725: Changes in version 1.11.5, released on July 24, 2011
726:
727: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
728: input (although few GNU extensions are accepted, nor is mixing
729: low-level roff with eqn). See the eqn(7) manual for details.
730: For the time being, equations are rendered as simple in-line text.
731: The equation parser satisfies the language specified in the
732: Second Edition User's Guide:
733: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
734:
735: Changes in version 1.11.4, released on July 12, 2011
736:
737: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
738: and the man(7) parser. This release was significantly assisted by
739: participants in OpenBSD's c2k11. Thanks!
740:
741: Changes in version 1.11.3, released on May 26, 2011
742:
743: * Introduce locale-encoding of output with the -Tlocale output option and
744: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
745: respectively, for details. This allows for non-ASCII characters (e.g.,
746: \[u5000]) to be rendered in the locale's encoding, if said environment
747: supports wide-character encoding (if it does not, -Tascii is used
748: instead). Locale support can be turned off at compile time by removing
749: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
750: for -Tascii.
751: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
752: be on-the-fly recoded into mandoc(1) input by using the newly-added
753: preconv(1) utility. Note: in the future, this feature may be
754: integrated into mandoc(1).
755:
756: Changes in version 1.11.2, released on May 12, 2011
757:
758: * Corrected some installation issues in version 1.11.1.
759: * Further migration to libmandoc.
760: * Initial public release (this utility is very much under development)
761: of mandocdb(8). This utility produces keyword databases of manual
762: content, which features semantic querying of manual content.
763:
764: Changes in version 1.11.1, released on April 4, 2011
765:
766: * The earlier libroff, libmdoc, and libman soup have been merged into
767: a single library, libmandoc, which manages all aspects of parsing
768: real manuals, from line-handling to tbl(7) parsing.
769: * As usual, many general fixes and improvements have also occurred.
770: In particular, a great deal of redundancy and superfluous code has
771: been removed with the merging of the backend libraries.
1.3 schwarze 772: * see also the changes in 1.10.10
773:
774: Changes in version 1.10.10, March 20, 2011, NOT released
775:
776: * Initial eqn(7) functionality is in place. For the time being,
777: this is limited to the recognition of equation blocks;
778: future version of mdocml will expand upon this framework.
1.1 schwarze 779:
780: Changes in version 1.10.9, released on January 7, 2011
781:
782: * Many back-end fixes have been implemented: argument handling (quoting),
783: man(7) improvements, error/warning classes, and many more.
784: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
785: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
786: minimal, especially for -Thtml and -Txhtml, but manages to at least
787: display data. This means that mandoc(1) now has built-in support
788: for two troff preprocessors via libroff: soelim(1) and tbl(1).
789:
790: Changes in version 1.10.8, released on December 24, 2010
791:
1.3 schwarze 792: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 793: readable output in arbitrary browsers, including text-based ones like
794: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
795: for examples. Attention: available style-sheet classes have been
796: considerably changed! See the example.style.css file for details.
797: Lastly, libmdoc and libman have been cleaned up and reduced in size
798: and complexity.
1.3 schwarze 799: * see also the changes in 1.10.7
800:
801: Changes in version 1.10.7, December 6, 2010, NOT released
802:
803: Significant improvements merged from OpenBSD downstream, including:
804: * many new roff(7) components,
805: * in-line implementation of troff's soelim(1),
806: * broken-block handling,
807: * overhauled error classifications, and
808: * cleaned up handling of error conditions.
1.1 schwarze 809:
810: Changes in version 1.10.6, released on September 27, 2010
811:
812: * Calling conventions for mandoc(1) have changed: -W improved and -f
813: deprecated.
814: * Non-ASCII characters are also now uniformly discarded.
815: * Lots of documentation improvements.
816: * Many incremental fixes accomodating for groff's more interesting
817: productions.
818: * Lastly, pod2man(1) preambles are now fully accepted after some
819: considerable roff(7) and special character support.
820:
821: Changes in version 1.10.5, released on July 27, 2010
822:
823: * Primarily a bug-fix and polish release, but including -Tpdf support
824: in mandoc(1) by way of "Summer of Code". Highlights:
825: * fix "Sm" and "Bd" handling
826: * fix end-of-sentence handling for embedded sentences
827: * polish man(7) documentation
828: * document all mdoc(7) macros
829: * polish mandoc(1) -Tps output
830: * lots of internal clean-ups in character escapes
831: * un-break literal contexts in man(7) documents
832: * improve -Thtml output for -man
833: * add mandoc(1) -Tpdf support
834:
835: Changes in version 1.10.4, released on July 12, 2010
836:
837: * Lots of features developed during both "Summer of Code" and the
838: OpenBSD c2k10 hackathon:
839: * minimal "ds" roff(7) symbols are supported
840: * beautified SYNOPSIS section output
841: * acceptance of scope-block breakage in mdoc(7)
842: * clarify error message status
843: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 844: * see also changes in 1.10.3
845:
846: Changes in version 1.10.3, June 29, 2010, NOT released
847:
848: * variable font-width and paper-size support in mandoc(1) -Tps output
849: * "Bk" mdoc(7) support
1.1 schwarze 850:
851: Changes in version 1.10.2, released on June 19, 2010
852:
853: * Small release featuring text-decoration in -Tps output,
854: a few minor relaxations of errors, and some optimisations.
855:
856: Changes in version 1.10.1, released on June 7, 2010
857:
858: * This primarily focusses on the "Bl" and "It" macros described in
859: mdoc(7). Multi-line column support is now fully compatible with groff,
860: as are implicit list entries for columns.
861: * Removed manuals(7) in favour of http://manpages.bsd.lv.
862: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
863: in MANUAL STRUCTURE) has also been considerably simplified compared
864: to groff's method.
865: * Furthermore, the -Owidth=width output option has been added to -Tascii,
866: see mandoc(1).
867: * Lastly, initial PostScript output has been added with the -Tps option
868: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
869: font decorations.
870:
871: Changes in version 1.10.0, released on May 29, 2010
872:
873: * Release consisting of the results from the m2k10 hackathon and up-merge
874: from OpenBSD. This requires a significant note of thanks to Ingo
875: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
876: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
877: Ingo's m2k10 report) follow in no particular order:
878: * a libroff preprocessor in front of libmdoc and libman stripping out
879: roff(7) instructions;
880: * end-of-sentence (EOS) detection in free-form and macro lines;
881: * correct handling of tab-separated columnar lists in mdoc(7);
882: * improved main calling routines to optionally use mmap(3) for better
883: performance;
884: * cleaned up exiting when invoked as -Tlint or over multiple files
885: with -fign-errors;
886: * error and warning message handling re-written to be unified for
887: libroff, libmdoc, and libman;
888: * handling of badly-nested explicit-scoped macros;
889: * improved free-form text parsing in libman and libmdoc;
890: * significant GNU troff compatibility improvements in -Tascii,
891: largely in terms of spacing;
892: * a regression framework for making sure the many fragilities of GNU
893: troff aren't trampled in subsequent work;
894: * support for -Tascii breaking at hyphens encountered in free-form text;
895: * and many more minor fixes and improvements
896:
897: Changes in version 1.9.25, released on May 13, 2010
898:
899: * Fixed handling of "\*(Ba" escape.
900: * Backed out -fno-ign-chars (pointless complexity).
901: * Fixed erroneous breaking of literal lines.
902: * Fixed SYNOPSIS breaking lines before non-initial macros.
903: * Changed default section ordering.
904: * Most importantly, the framework for end-of-sentence double-spacing is
905: in place, now implemented for the "end-of-sentence, end-of-line" rule.
906: * This is a stable roll-back point before the mandoc hackathon in Rostock!
907:
908: Changes in version 1.9.24, released on May 9, 2010
909:
910: * Rolled back break-at-hyphen.
911: * -DUGLY is now the default (no feature splits!).
912: * Free-form text is not de-chunked any more: lines are passed
913: whole-sale into the front-end, including whitespace.
914: * Added mailing lists.
915:
916: Changes in version 1.9.23, released on April 7, 2010
917:
918: * mdocml has been linked to the OpenBSD build.
919: * This version incorporates many small changes, mostly from patches
920: by OpenBSD, allowing crufty manuals to slip by with warnings instead
921: of erroring-out.
922: * Some subtle semantic issues, such as punctuation scope, have also
923: been fixed.
924: * Lastly, some issues with -Thtml have been fixed, which prompted an
925: update to the online manual pages style layout.
926:
927: Changes in version 1.9.22, released on March 31, 2010
928:
929: * Adjusted merge of the significant work by Ingo Schwarze
930: in getting "Xo" blocks (block full implicit, e.g., "It"
931: for non-columnar lists) to work properly. This isn't
932: enabled by default: you must specify -DUGLY as a compiler
933: flag (see the Makefile for details).
934:
935: Changes in version 1.9.20, released on March 30, 2010
936:
937: * More efforts to get roff instructions in man(7) documents under
938: control. Note that roff instructions embedded in line-scoped,
939: next-line macros (e.g. "B") are not supported.
940: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
941: are now correctly handled.
942:
943: Changes in version 1.9.18, released on March 27, 2010
944:
945: * Many fixes (largely pertaining to scope)
946: and improvements (e.g., handling of apostrophe-control macros,
947: which fixes the strange "BR" seen in some macro output)
948: to handling roff instructions in man(7) documents.
949:
950: Changes in version 1.9.17, released on March 25, 2010
951:
952: * Accept perlpod(1) standard preamble.
953: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
954: roff macro blocks.
955:
956: Changes in version 1.9.16, released on March 22, 2010
957:
958: * Inspired by patches and bug reports by Ingo Schwarze,
959: allowed man(7) to accept non-printing elements to be nested
960: within next-line scopes, such as "br" within "B" or "TH",
961: which is valid roff.
962: * Longsoon architecture also noted and Makefile cleaned up.
963:
964: Changes in version 1.9.15, released on February 18, 2010
965:
966: * Moved to our new BSD.lv home.
967: * XHTML is now an acceptable output mode for mandoc(1);
968: * "Xr" made more compatible with groff;
969: * "Vt" fixed when invoked in SYNOPSIS;
970: * "\\" escape removed;
971: * end-of-line white-space detected for all lines;
972: * subtle bug fixed in list display for some modes;
973: * compatibility layer checked in for compilation in diverse
974: UNIX systems;
975: * and column lengths handled correctly.
