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

560: * The mdoc(7) formatter non partially supports .Bd -centered.
561: * tbl(7) now handles leading and trailing vertical lines.
562: * The build system now provides fallback versions of strcasestr(3)
563: and strsep(3) for systems lacking them.

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

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

608:
609: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
610: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
611: Thanks to Franco Fichtner for doing part of the work.
612: * The mdoc(7) .Bk macro got some addititonal bugfixes.
613: * In mdoc(7) macro arguments, double quotes can now be quoted
614: by doubling them, just like in man(7).
615: Thanks to Tsugutomo ENAMI for the patch.
616: * At the end of man(7) macro lines, end-of-sentence spacing
617: now works. Thanks to Franco Fichtner for the patch.
618: * For backward compatibility, the man(7) parser now supports the
619: man-ext .UR/.UE (uniform resource identifier) block macros.
620: * The man(7) parser now handles closing blocks that are not open
621: more gracefully.
622: * The man(7) parser now ignores blank lines right after .SH and .SS.
623: * In the man(7) formatter, reset indentation when leaving a block,
624: not just when entering the next one.
625: * The roff(7) .nr request now supports incrementing and decrementing
626: number registers and stops parsing the number right before the
627: first non-digit character.
628: * The roff(7) parser now supports the alternative escape sequence
629: syntax \C'uXXXX' for Unicode characters.
630: * The roff(7) parser now parses and ignores the .fam (font family)
631: and .hw (hyphenation points) requests and the \d and \u escape
632: sequences.
633: * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
1.1 schwarze 634:
1.2 schwarze 635: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 636:
637: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
638: is now fully functional.
639: * The mandoc(1) utility now supports the -Ios (default operating system)
640: input option, and the -Tutf8 output mode now actually works.
641: * The mandocdb(8) utility no longer truncates existing databases when
642: starting to build new ones, but only replaces them when the build
643: actually succeeds.
644: * The man(7) parser now supports the PD macro (paragraph distance),
645: and (for GNU man-ext compatibility only) EX (example block) and EE
646: (example end). Plus several bugfixes regarding indentation, line
647: breaks, and vertical spacing, and regarding RS following TP.
648: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
649: the \z (zero cursor advance) escape and the cc (change control
650: character) and it (input line trap) requests. Plus bugfixes regarding
651: the \t (tab) escape, nested escape sequences, and conditional requests.
652: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
653: enclosures, delimiter handling, list indentation and horizontal and
654: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
655: bugfixes related to the handling of syntax errors like badly nested
656: font blocks, stray Ta macros outside column lists, unterminated It Xo
657: blocks, and non-text children of Nm blocks.
658: * In tbl(7), the width of horizontal spans and the vertical spacing
659: around tables was corrected, and in man(7) files, a crash was fixed
660: that was triggered by some particular unclosed T{ macros.
661: * For mandoc developers, we now provide a tbl(3) library manual and
662: gmdiff, a very small, very simplistic groff-versus-mandoc output
663: comparison tool.
1.2 schwarze 664: * Provide this NEWS file.
1.1 schwarze 665:
666: Changes in version 1.12.1, released on March 23, 2012
667:
668: * Significant work on apropos(1) and mandocdb(8). These tools are now
669: much more robust. A whatis(1) implementation is now handled as an
670: apropos(1) mode. These tools are also able to minimally handle
671: pre-formatted pages, that is, those already formatted by another
672: utility such as GNU troff.
673: * The man.cgi(7) script is also now available for wider testing.
674: It interfaces with mandocdb(8) manuals cached by catman(8).
675: HTML output is generated on-the-fly by libmandoc or internal
676: methods to convert pre-formatted pages.
677: * The mailing list archive for the discuss and tech lists are being
678: hosted by Gmane at gmane.comp.tools.mdocml.user and
679: gmane.comp.tools.mdocml.devel, respectively.
680:
681: Changes in version 1.12.0, released on October 8, 2011
682:
683: * This version features a new, work-in-progress mandoc(1) output mode:
684: -Tman. This mode allows a system maintainer to distribute man(7)
685: media for older systems that may not natively support mdoc(7), such
686: as old Solaris systems.
687: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
688: * While adding features, an apropos(1) utility has been merged from the
689: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
690: search of manual content. apropos(1) is different from the traditional
691: apropos primarily in allowing keyword search (such as for functions,
692: utilities, etc.) and regular expressions. Note that the calling
693: syntax for apropos is likely to change as it settles down.
694: * In documentation news, the mdoc(7) and man(7) manuals have been
695: made considerably more readable by adding MACRO OVERVIEW sections, by
696: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
697: and by moving the very technical MACRO SYNTAX sections down to the
698: bottom of the page.
699: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
700: was rewritten completely. It is now compatible with groff(1), both
701: with and without frames and rulers.
702: * Nesting of indented blocks is now supported in man(7), and several
703: bugs were fixed regarding indentation and alignment.
704: * The page headers in mdoc(7) are now nicer for very long titles.
705:
706: Changes in version 1.11.7, released on September 2, 2011
707:
708: * Added demandoc(1) utility for stripping away macros and escapes.
709: This replaces the historical deroff(1) utility.
710: * Also improved the mdoc(7) and man(7) manuals.
711:
712: Changes in version 1.11.6, released on August 16, 2011
713:
714: * Handling of tr macro in roff(7) implemented. This makes Perl
715: documentation much more readable. Hyphenation is also now enabled in
716: man(7) format documents. Many other general improvements have been
717: implemented.
718:
719: Changes in version 1.11.5, released on July 24, 2011
720:
721: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
722: input (although few GNU extensions are accepted, nor is mixing
723: low-level roff with eqn). See the eqn(7) manual for details.
724: For the time being, equations are rendered as simple in-line text.
725: The equation parser satisfies the language specified in the
726: Second Edition User's Guide:
727: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
728:
729: Changes in version 1.11.4, released on July 12, 2011
730:
731: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
732: and the man(7) parser. This release was significantly assisted by
733: participants in OpenBSD's c2k11. Thanks!
734:
735: Changes in version 1.11.3, released on May 26, 2011
736:
737: * Introduce locale-encoding of output with the -Tlocale output option and
738: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
739: respectively, for details. This allows for non-ASCII characters (e.g.,
740: \[u5000]) to be rendered in the locale's encoding, if said environment
741: supports wide-character encoding (if it does not, -Tascii is used
742: instead). Locale support can be turned off at compile time by removing
743: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
744: for -Tascii.
745: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
746: be on-the-fly recoded into mandoc(1) input by using the newly-added
747: preconv(1) utility. Note: in the future, this feature may be
748: integrated into mandoc(1).
749:
750: Changes in version 1.11.2, released on May 12, 2011
751:
752: * Corrected some installation issues in version 1.11.1.
753: * Further migration to libmandoc.
754: * Initial public release (this utility is very much under development)
755: of mandocdb(8). This utility produces keyword databases of manual
756: content, which features semantic querying of manual content.
757:
758: Changes in version 1.11.1, released on April 4, 2011
759:
760: * The earlier libroff, libmdoc, and libman soup have been merged into
761: a single library, libmandoc, which manages all aspects of parsing
762: real manuals, from line-handling to tbl(7) parsing.
763: * As usual, many general fixes and improvements have also occurred.
764: In particular, a great deal of redundancy and superfluous code has
765: been removed with the merging of the backend libraries.
1.3 schwarze 766: * see also the changes in 1.10.10
767:
768: Changes in version 1.10.10, March 20, 2011, NOT released
769:
770: * Initial eqn(7) functionality is in place. For the time being,
771: this is limited to the recognition of equation blocks;
772: future version of mdocml will expand upon this framework.
1.1 schwarze 773:
774: Changes in version 1.10.9, released on January 7, 2011
775:
776: * Many back-end fixes have been implemented: argument handling (quoting),
777: man(7) improvements, error/warning classes, and many more.
778: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
779: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
780: minimal, especially for -Thtml and -Txhtml, but manages to at least
781: display data. This means that mandoc(1) now has built-in support
782: for two troff preprocessors via libroff: soelim(1) and tbl(1).
783:
784: Changes in version 1.10.8, released on December 24, 2010
785:
1.3 schwarze 786: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 787: readable output in arbitrary browsers, including text-based ones like
788: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
789: for examples. Attention: available style-sheet classes have been
790: considerably changed! See the example.style.css file for details.
791: Lastly, libmdoc and libman have been cleaned up and reduced in size
792: and complexity.
1.3 schwarze 793: * see also the changes in 1.10.7
794:
795: Changes in version 1.10.7, December 6, 2010, NOT released
796:
797: Significant improvements merged from OpenBSD downstream, including:
798: * many new roff(7) components,
799: * in-line implementation of troff's soelim(1),
800: * broken-block handling,
801: * overhauled error classifications, and
802: * cleaned up handling of error conditions.
1.1 schwarze 803:
804: Changes in version 1.10.6, released on September 27, 2010
805:
806: * Calling conventions for mandoc(1) have changed: -W improved and -f
807: deprecated.
808: * Non-ASCII characters are also now uniformly discarded.
809: * Lots of documentation improvements.
810: * Many incremental fixes accomodating for groff's more interesting
811: productions.
812: * Lastly, pod2man(1) preambles are now fully accepted after some
813: considerable roff(7) and special character support.
814:
815: Changes in version 1.10.5, released on July 27, 2010
816:
817: * Primarily a bug-fix and polish release, but including -Tpdf support
818: in mandoc(1) by way of "Summer of Code". Highlights:
819: * fix "Sm" and "Bd" handling
820: * fix end-of-sentence handling for embedded sentences
821: * polish man(7) documentation
822: * document all mdoc(7) macros
823: * polish mandoc(1) -Tps output
824: * lots of internal clean-ups in character escapes
825: * un-break literal contexts in man(7) documents
826: * improve -Thtml output for -man
827: * add mandoc(1) -Tpdf support
828:
829: Changes in version 1.10.4, released on July 12, 2010
830:
831: * Lots of features developed during both "Summer of Code" and the
832: OpenBSD c2k10 hackathon:
833: * minimal "ds" roff(7) symbols are supported
834: * beautified SYNOPSIS section output
835: * acceptance of scope-block breakage in mdoc(7)
836: * clarify error message status
837: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 838: * see also changes in 1.10.3
839:
840: Changes in version 1.10.3, June 29, 2010, NOT released
841:
842: * variable font-width and paper-size support in mandoc(1) -Tps output
843: * "Bk" mdoc(7) support
1.1 schwarze 844:
845: Changes in version 1.10.2, released on June 19, 2010
846:
847: * Small release featuring text-decoration in -Tps output,
848: a few minor relaxations of errors, and some optimisations.
849:
850: Changes in version 1.10.1, released on June 7, 2010
851:
852: * This primarily focusses on the "Bl" and "It" macros described in
853: mdoc(7). Multi-line column support is now fully compatible with groff,
854: as are implicit list entries for columns.
855: * Removed manuals(7) in favour of http://manpages.bsd.lv.
856: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
857: in MANUAL STRUCTURE) has also been considerably simplified compared
858: to groff's method.
859: * Furthermore, the -Owidth=width output option has been added to -Tascii,
860: see mandoc(1).
861: * Lastly, initial PostScript output has been added with the -Tps option
862: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
863: font decorations.
864:
865: Changes in version 1.10.0, released on May 29, 2010
866:
867: * Release consisting of the results from the m2k10 hackathon and up-merge
868: from OpenBSD. This requires a significant note of thanks to Ingo
869: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
870: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
871: Ingo's m2k10 report) follow in no particular order:
872: * a libroff preprocessor in front of libmdoc and libman stripping out
873: roff(7) instructions;
874: * end-of-sentence (EOS) detection in free-form and macro lines;
875: * correct handling of tab-separated columnar lists in mdoc(7);
876: * improved main calling routines to optionally use mmap(3) for better
877: performance;
878: * cleaned up exiting when invoked as -Tlint or over multiple files
879: with -fign-errors;
880: * error and warning message handling re-written to be unified for
881: libroff, libmdoc, and libman;
882: * handling of badly-nested explicit-scoped macros;
883: * improved free-form text parsing in libman and libmdoc;
884: * significant GNU troff compatibility improvements in -Tascii,
885: largely in terms of spacing;
886: * a regression framework for making sure the many fragilities of GNU
887: troff aren't trampled in subsequent work;
888: * support for -Tascii breaking at hyphens encountered in free-form text;
889: * and many more minor fixes and improvements
890:
891: Changes in version 1.9.25, released on May 13, 2010
892:
893: * Fixed handling of "\*(Ba" escape.
894: * Backed out -fno-ign-chars (pointless complexity).
895: * Fixed erroneous breaking of literal lines.
896: * Fixed SYNOPSIS breaking lines before non-initial macros.
897: * Changed default section ordering.
898: * Most importantly, the framework for end-of-sentence double-spacing is
899: in place, now implemented for the "end-of-sentence, end-of-line" rule.
900: * This is a stable roll-back point before the mandoc hackathon in Rostock!
901:
902: Changes in version 1.9.24, released on May 9, 2010
903:
904: * Rolled back break-at-hyphen.
905: * -DUGLY is now the default (no feature splits!).
906: * Free-form text is not de-chunked any more: lines are passed
907: whole-sale into the front-end, including whitespace.
908: * Added mailing lists.
909:
910: Changes in version 1.9.23, released on April 7, 2010
911:
912: * mdocml has been linked to the OpenBSD build.
913: * This version incorporates many small changes, mostly from patches
914: by OpenBSD, allowing crufty manuals to slip by with warnings instead
915: of erroring-out.
916: * Some subtle semantic issues, such as punctuation scope, have also
917: been fixed.
918: * Lastly, some issues with -Thtml have been fixed, which prompted an
919: update to the online manual pages style layout.
920:
921: Changes in version 1.9.22, released on March 31, 2010
922:
923: * Adjusted merge of the significant work by Ingo Schwarze
924: in getting "Xo" blocks (block full implicit, e.g., "It"
925: for non-columnar lists) to work properly. This isn't
926: enabled by default: you must specify -DUGLY as a compiler
927: flag (see the Makefile for details).
928:
929: Changes in version 1.9.20, released on March 30, 2010
930:
931: * More efforts to get roff instructions in man(7) documents under
932: control. Note that roff instructions embedded in line-scoped,
933: next-line macros (e.g. "B") are not supported.
934: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
935: are now correctly handled.
936:
937: Changes in version 1.9.18, released on March 27, 2010
938:
939: * Many fixes (largely pertaining to scope)
940: and improvements (e.g., handling of apostrophe-control macros,
941: which fixes the strange "BR" seen in some macro output)
942: to handling roff instructions in man(7) documents.
943:
944: Changes in version 1.9.17, released on March 25, 2010
945:
946: * Accept perlpod(1) standard preamble.
947: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
948: roff macro blocks.
949:
950: Changes in version 1.9.16, released on March 22, 2010
951:
952: * Inspired by patches and bug reports by Ingo Schwarze,
953: allowed man(7) to accept non-printing elements to be nested
954: within next-line scopes, such as "br" within "B" or "TH",
955: which is valid roff.
956: * Longsoon architecture also noted and Makefile cleaned up.
957:
958: Changes in version 1.9.15, released on February 18, 2010
959:
960: * Moved to our new BSD.lv home.
961: * XHTML is now an acceptable output mode for mandoc(1);
962: * "Xr" made more compatible with groff;
963: * "Vt" fixed when invoked in SYNOPSIS;
964: * "\\" escape removed;
965: * end-of-line white-space detected for all lines;
966: * subtle bug fixed in list display for some modes;
967: * compatibility layer checked in for compilation in diverse
968: UNIX systems;
969: * and column lengths handled correctly.
