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

576: * In the mdoc(7) parser, trailing punctuation at the end of partial
577: implicit macros no longer triggers end-of-sentence spacing.
578: * In the terminal formatter, two crashes were fixed: one triggered by

580: * In the terminal formatter, a floating point rounding bug was
581: fixed that sometimes caused an off-by-one error in indentation.
582: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
583: and non-breakable spaces was corrected.
584: * In the HTML formatter, encoding of special characters was
585: corrected in multiple respects.
586: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
587: improved for various edge cases.
588: * In the mdoc(7) formatter, handling of empty .Bl -inset item
589: heads was improved.
590: * In the man(7) formatter, some bugs were fixed with respect
591: to same-line detection in the context of .TP and .nf macros,
592: and the indentation of .IP and .TP blocks was improved.
593: * The mandoc(3) library no longer prints to stderr.

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

1.2 schwarze 633: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 634:
635: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
636: is now fully functional.
637: * The mandoc(1) utility now supports the -Ios (default operating system)
638: input option, and the -Tutf8 output mode now actually works.
639: * The mandocdb(8) utility no longer truncates existing databases when
640: starting to build new ones, but only replaces them when the build
641: actually succeeds.
642: * The man(7) parser now supports the PD macro (paragraph distance),
643: and (for GNU man-ext compatibility only) EX (example block) and EE
644: (example end). Plus several bugfixes regarding indentation, line
645: breaks, and vertical spacing, and regarding RS following TP.
646: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
647: the \z (zero cursor advance) escape and the cc (change control
648: character) and it (input line trap) requests. Plus bugfixes regarding
649: the \t (tab) escape, nested escape sequences, and conditional requests.
650: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
651: enclosures, delimiter handling, list indentation and horizontal and
652: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
653: bugfixes related to the handling of syntax errors like badly nested
654: font blocks, stray Ta macros outside column lists, unterminated It Xo
655: blocks, and non-text children of Nm blocks.
656: * In tbl(7), the width of horizontal spans and the vertical spacing
657: around tables was corrected, and in man(7) files, a crash was fixed
658: that was triggered by some particular unclosed T{ macros.
659: * For mandoc developers, we now provide a tbl(3) library manual and
660: gmdiff, a very small, very simplistic groff-versus-mandoc output
661: comparison tool.
1.2 schwarze 662: * Provide this NEWS file.
1.1 schwarze 663:
664: Changes in version 1.12.1, released on March 23, 2012
665:
666: * Significant work on apropos(1) and mandocdb(8). These tools are now
667: much more robust. A whatis(1) implementation is now handled as an
668: apropos(1) mode. These tools are also able to minimally handle
669: pre-formatted pages, that is, those already formatted by another
670: utility such as GNU troff.
671: * The man.cgi(7) script is also now available for wider testing.
672: It interfaces with mandocdb(8) manuals cached by catman(8).
673: HTML output is generated on-the-fly by libmandoc or internal
674: methods to convert pre-formatted pages.
675: * The mailing list archive for the discuss and tech lists are being
676: hosted by Gmane at gmane.comp.tools.mdocml.user and
677: gmane.comp.tools.mdocml.devel, respectively.
678:
679: Changes in version 1.12.0, released on October 8, 2011
680:
681: * This version features a new, work-in-progress mandoc(1) output mode:
682: -Tman. This mode allows a system maintainer to distribute man(7)
683: media for older systems that may not natively support mdoc(7), such
684: as old Solaris systems.
685: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
686: * While adding features, an apropos(1) utility has been merged from the
687: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
688: search of manual content. apropos(1) is different from the traditional
689: apropos primarily in allowing keyword search (such as for functions,
690: utilities, etc.) and regular expressions. Note that the calling
691: syntax for apropos is likely to change as it settles down.
692: * In documentation news, the mdoc(7) and man(7) manuals have been
693: made considerably more readable by adding MACRO OVERVIEW sections, by
694: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
695: and by moving the very technical MACRO SYNTAX sections down to the
696: bottom of the page.
697: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
698: was rewritten completely. It is now compatible with groff(1), both
699: with and without frames and rulers.
700: * Nesting of indented blocks is now supported in man(7), and several
701: bugs were fixed regarding indentation and alignment.
702: * The page headers in mdoc(7) are now nicer for very long titles.
703:
704: Changes in version 1.11.7, released on September 2, 2011
705:
706: * Added demandoc(1) utility for stripping away macros and escapes.
707: This replaces the historical deroff(1) utility.
708: * Also improved the mdoc(7) and man(7) manuals.
709:
710: Changes in version 1.11.6, released on August 16, 2011
711:
712: * Handling of tr macro in roff(7) implemented. This makes Perl
713: documentation much more readable. Hyphenation is also now enabled in
714: man(7) format documents. Many other general improvements have been
715: implemented.
716:
717: Changes in version 1.11.5, released on July 24, 2011
718:
719: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
720: input (although few GNU extensions are accepted, nor is mixing
721: low-level roff with eqn). See the eqn(7) manual for details.
722: For the time being, equations are rendered as simple in-line text.
723: The equation parser satisfies the language specified in the
724: Second Edition User's Guide:
725: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
726:
727: Changes in version 1.11.4, released on July 12, 2011
728:
729: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
730: and the man(7) parser. This release was significantly assisted by
731: participants in OpenBSD's c2k11. Thanks!
732:
733: Changes in version 1.11.3, released on May 26, 2011
734:
735: * Introduce locale-encoding of output with the -Tlocale output option and
736: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
737: respectively, for details. This allows for non-ASCII characters (e.g.,
738: \[u5000]) to be rendered in the locale's encoding, if said environment
739: supports wide-character encoding (if it does not, -Tascii is used
740: instead). Locale support can be turned off at compile time by removing
741: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
742: for -Tascii.
743: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
744: be on-the-fly recoded into mandoc(1) input by using the newly-added
745: preconv(1) utility. Note: in the future, this feature may be
746: integrated into mandoc(1).
747:
748: Changes in version 1.11.2, released on May 12, 2011
749:
750: * Corrected some installation issues in version 1.11.1.
751: * Further migration to libmandoc.
752: * Initial public release (this utility is very much under development)
753: of mandocdb(8). This utility produces keyword databases of manual
754: content, which features semantic querying of manual content.
755:
756: Changes in version 1.11.1, released on April 4, 2011
757:
758: * The earlier libroff, libmdoc, and libman soup have been merged into
759: a single library, libmandoc, which manages all aspects of parsing
760: real manuals, from line-handling to tbl(7) parsing.
761: * As usual, many general fixes and improvements have also occurred.
762: In particular, a great deal of redundancy and superfluous code has
763: been removed with the merging of the backend libraries.
1.3 schwarze 764: * see also the changes in 1.10.10
765:
766: Changes in version 1.10.10, March 20, 2011, NOT released
767:
768: * Initial eqn(7) functionality is in place. For the time being,
769: this is limited to the recognition of equation blocks;
770: future version of mdocml will expand upon this framework.

772: Changes in version 1.10.9, released on January 7, 2011
773:
774: * Many back-end fixes have been implemented: argument handling (quoting),
775: man(7) improvements, error/warning classes, and many more.
776: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
777: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
778: minimal, especially for -Thtml and -Txhtml, but manages to at least
779: display data. This means that mandoc(1) now has built-in support
780: for two troff preprocessors via libroff: soelim(1) and tbl(1).
781:
782: Changes in version 1.10.8, released on December 24, 2010
783:
1.3 schwarze 784: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 785: readable output in arbitrary browsers, including text-based ones like
786: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
787: for examples. Attention: available style-sheet classes have been
788: considerably changed! See the example.style.css file for details.
789: Lastly, libmdoc and libman have been cleaned up and reduced in size
790: and complexity.
1.3 schwarze 791: * see also the changes in 1.10.7
792:
793: Changes in version 1.10.7, December 6, 2010, NOT released
794:
795: Significant improvements merged from OpenBSD downstream, including:
796: * many new roff(7) components,
797: * in-line implementation of troff's soelim(1),
798: * broken-block handling,
799: * overhauled error classifications, and
800: * cleaned up handling of error conditions.
1.1 schwarze 801:
802: Changes in version 1.10.6, released on September 27, 2010
803:
804: * Calling conventions for mandoc(1) have changed: -W improved and -f
805: deprecated.
806: * Non-ASCII characters are also now uniformly discarded.
807: * Lots of documentation improvements.
808: * Many incremental fixes accomodating for groff's more interesting
809: productions.
810: * Lastly, pod2man(1) preambles are now fully accepted after some
811: considerable roff(7) and special character support.
812:
813: Changes in version 1.10.5, released on July 27, 2010
814:
815: * Primarily a bug-fix and polish release, but including -Tpdf support
816: in mandoc(1) by way of "Summer of Code". Highlights:
817: * fix "Sm" and "Bd" handling
818: * fix end-of-sentence handling for embedded sentences
819: * polish man(7) documentation
820: * document all mdoc(7) macros
821: * polish mandoc(1) -Tps output
822: * lots of internal clean-ups in character escapes
823: * un-break literal contexts in man(7) documents
824: * improve -Thtml output for -man
825: * add mandoc(1) -Tpdf support
826:
827: Changes in version 1.10.4, released on July 12, 2010
828:
829: * Lots of features developed during both "Summer of Code" and the
830: OpenBSD c2k10 hackathon:
831: * minimal "ds" roff(7) symbols are supported
832: * beautified SYNOPSIS section output
833: * acceptance of scope-block breakage in mdoc(7)
834: * clarify error message status
835: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 836: * see also changes in 1.10.3
837:
838: Changes in version 1.10.3, June 29, 2010, NOT released
839:
840: * variable font-width and paper-size support in mandoc(1) -Tps output
841: * "Bk" mdoc(7) support
1.1 schwarze 842:
843: Changes in version 1.10.2, released on June 19, 2010
844:
845: * Small release featuring text-decoration in -Tps output,
846: a few minor relaxations of errors, and some optimisations.
847:
848: Changes in version 1.10.1, released on June 7, 2010
849:
850: * This primarily focusses on the "Bl" and "It" macros described in
851: mdoc(7). Multi-line column support is now fully compatible with groff,
852: as are implicit list entries for columns.
853: * Removed manuals(7) in favour of http://manpages.bsd.lv.
854: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
855: in MANUAL STRUCTURE) has also been considerably simplified compared
856: to groff's method.
857: * Furthermore, the -Owidth=width output option has been added to -Tascii,
858: see mandoc(1).
859: * Lastly, initial PostScript output has been added with the -Tps option
860: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
861: font decorations.
862:
863: Changes in version 1.10.0, released on May 29, 2010
864:
865: * Release consisting of the results from the m2k10 hackathon and up-merge
866: from OpenBSD. This requires a significant note of thanks to Ingo
867: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
868: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
869: Ingo's m2k10 report) follow in no particular order:
870: * a libroff preprocessor in front of libmdoc and libman stripping out
871: roff(7) instructions;
872: * end-of-sentence (EOS) detection in free-form and macro lines;
873: * correct handling of tab-separated columnar lists in mdoc(7);
874: * improved main calling routines to optionally use mmap(3) for better
875: performance;
876: * cleaned up exiting when invoked as -Tlint or over multiple files
877: with -fign-errors;
878: * error and warning message handling re-written to be unified for
879: libroff, libmdoc, and libman;
880: * handling of badly-nested explicit-scoped macros;
881: * improved free-form text parsing in libman and libmdoc;
882: * significant GNU troff compatibility improvements in -Tascii,
883: largely in terms of spacing;
884: * a regression framework for making sure the many fragilities of GNU
885: troff aren't trampled in subsequent work;
886: * support for -Tascii breaking at hyphens encountered in free-form text;
887: * and many more minor fixes and improvements
888:
889: Changes in version 1.9.25, released on May 13, 2010
890:
891: * Fixed handling of "\*(Ba" escape.
892: * Backed out -fno-ign-chars (pointless complexity).
893: * Fixed erroneous breaking of literal lines.
894: * Fixed SYNOPSIS breaking lines before non-initial macros.
895: * Changed default section ordering.
896: * Most importantly, the framework for end-of-sentence double-spacing is
897: in place, now implemented for the "end-of-sentence, end-of-line" rule.
898: * This is a stable roll-back point before the mandoc hackathon in Rostock!
899:
900: Changes in version 1.9.24, released on May 9, 2010
901:
902: * Rolled back break-at-hyphen.
903: * -DUGLY is now the default (no feature splits!).
904: * Free-form text is not de-chunked any more: lines are passed
905: whole-sale into the front-end, including whitespace.
906: * Added mailing lists.
907:
908: Changes in version 1.9.23, released on April 7, 2010
909:
910: * mdocml has been linked to the OpenBSD build.
911: * This version incorporates many small changes, mostly from patches
912: by OpenBSD, allowing crufty manuals to slip by with warnings instead
913: of erroring-out.
914: * Some subtle semantic issues, such as punctuation scope, have also
915: been fixed.
916: * Lastly, some issues with -Thtml have been fixed, which prompted an
917: update to the online manual pages style layout.
918:
919: Changes in version 1.9.22, released on March 31, 2010
920:
921: * Adjusted merge of the significant work by Ingo Schwarze
922: in getting "Xo" blocks (block full implicit, e.g., "It"
923: for non-columnar lists) to work properly. This isn't
924: enabled by default: you must specify -DUGLY as a compiler
925: flag (see the Makefile for details).
926:
927: Changes in version 1.9.20, released on March 30, 2010
928:
929: * More efforts to get roff instructions in man(7) documents under
930: control. Note that roff instructions embedded in line-scoped,
931: next-line macros (e.g. "B") are not supported.
932: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
933: are now correctly handled.
934:
935: Changes in version 1.9.18, released on March 27, 2010
936:
937: * Many fixes (largely pertaining to scope)
938: and improvements (e.g., handling of apostrophe-control macros,
939: which fixes the strange "BR" seen in some macro output)
940: to handling roff instructions in man(7) documents.
941:
942: Changes in version 1.9.17, released on March 25, 2010
943:
944: * Accept perlpod(1) standard preamble.
945: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
946: roff macro blocks.
947:
948: Changes in version 1.9.16, released on March 22, 2010
949:
950: * Inspired by patches and bug reports by Ingo Schwarze,
951: allowed man(7) to accept non-printing elements to be nested
952: within next-line scopes, such as "br" within "B" or "TH",
953: which is valid roff.
954: * Longsoon architecture also noted and Makefile cleaned up.
955:
956: Changes in version 1.9.15, released on February 18, 2010
957:
958: * Moved to our new BSD.lv home.
959: * XHTML is now an acceptable output mode for mandoc(1);
960: * "Xr" made more compatible with groff;
961: * "Vt" fixed when invoked in SYNOPSIS;
962: * "\\" escape removed;
963: * end-of-line white-space detected for all lines;
964: * subtle bug fixed in list display for some modes;
965: * compatibility layer checked in for compilation in diverse
966: UNIX systems;
967: * and column lengths handled correctly.
