446:
447: --- MAJOR NEW FEATURES ---
448: * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite
449: based on SQLite3 is now included.
450: * The roff(7) parser now provides an almost complete implementation
451: of numerical expressions.
452: * Warning and error messages have been improved in many ways.
453: Almost all fatal errors were downgraded to normal errors and some
454: even to warnings. Almost all messages now mention the macro where
455: the issue is detected and many indicate the workaround employed.
456: The mandoc(1) manual now includes a list explaining all messages.
457: --- MINOR NEW FEATURES ---
458: * The roff(7) parser now supports the .ami (append to macro with
459: indirectly specified name), .as (append to user-defined
460: string), .dei (define macro with indirectly specified name),
461: .ll (line length), and .rr (remove register) requests.
462: * The roff(7) parser now supports string comparison and numerical
463: conditionals in the .if and .ie requests.
464: * The roff parser now fully supports the \B (validate numerical
465: expression) and partially supports the \w (measure text width)
466: escape sequences.
467: * The terminal formatter now supports the \: (optional line break)
468: escape sequence.
469: * The roff parser now supports expansion of user-defined strings
470: involving indirect references.
471: * The roff(7) parser now handles some pre-defined read-only
472: number registers that occur in the pod2man(1) preamble.
473: * For backward compatibility, the mdoc(7) parser and formatters
474: now support the obsolete macros .En, .Es, .Fr, and .Ot.
475: * The mdoc(7) formatter non partially supports .Bd -centered.
476: * tbl(7) now handles leading and trailing vertical lines.
477: * The build system now provides fallback versions of strcasestr(3)
478: and strsep(3) for systems lacking them.
479: * The mdoc(7) manual now explains how various standards
480: supported by the .St macro are related to each other.
481: --- BUGFIXES ---
482: * In the roff(7) parser, several bugs were fixed with respect
483: to closing conditional blocks on macro lines.
484: * Parsing of roff(7) identifiers and escape sequences was improved
485: in multiple respects.
486: * In the mdoc(7) parser, the handling of defective document
487: prologues was improved in multiple ways.
488: * The mdoc(7) parser no longer skips content before the first section
489: header, and it no longer deletes non-.% content from .Rs blocks.
490: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
491: * In the mdoc(7) parser, handling of .Sm with missing or invalid
492: arguments was corrected.
493: * In the mdoc(7) parser, trailing punctuation at the end of partial
494: implicit macros no longer triggers end-of-sentence spacing.
495: * In the terminal formatter, two crashes were fixed: one triggered by
496: excessive indentation and another by excessively long .Nm arguments.
497: * In the terminal formatter, a floating point rounding bug was
498: fixed that sometimes caused an off-by-one error in indentation.
499: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
500: and non-breakable spaces was corrected.
501: * In the HTML formatter, encoding of special characters was
502: corrected in multiple respects.
503: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
504: improved for various edge cases.
505: * In the mdoc(7) formatter, handling of empty .Bl -inset item
506: heads was improved.
507: * In the man(7) formatter, some bugs were fixed with respect
508: to same-line detection in the context of .TP and .nf macros,
509: and the indentation of .IP and .TP blocks was improved.
510: * The mandoc(3) library no longer prints to stderr.

1.4 schwarze 521:
522: Changes in version 1.12.3, released on December 31, 2013
523:
524: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
525: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
526: Thanks to Franco Fichtner for doing part of the work.
527: * The mdoc(7) .Bk macro got some addititonal bugfixes.
528: * In mdoc(7) macro arguments, double quotes can now be quoted
529: by doubling them, just like in man(7).
530: Thanks to Tsugutomo ENAMI for the patch.
531: * At the end of man(7) macro lines, end-of-sentence spacing
532: now works. Thanks to Franco Fichtner for the patch.
533: * For backward compatibility, the man(7) parser now supports the
534: man-ext .UR/.UE (uniform resource identifier) block macros.
535: * The man(7) parser now handles closing blocks that are not open
536: more gracefully.
537: * The man(7) parser now ignores blank lines right after .SH and .SS.
538: * In the man(7) formatter, reset indentation when leaving a block,
539: not just when entering the next one.
540: * The roff(7) .nr request now supports incrementing and decrementing
541: number registers and stops parsing the number right before the
542: first non-digit character.
543: * The roff(7) parser now supports the alternative escape sequence
544: syntax \C'uXXXX' for Unicode characters.
545: * The roff(7) parser now parses and ignores the .fam (font family)
546: and .hw (hyphenation points) requests and the \d and \u escape
547: sequences.
548: * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
1.1 schwarze 549:
1.2 schwarze 550: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 551:
552: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
553: is now fully functional.
554: * The mandoc(1) utility now supports the -Ios (default operating system)
555: input option, and the -Tutf8 output mode now actually works.
556: * The mandocdb(8) utility no longer truncates existing databases when
557: starting to build new ones, but only replaces them when the build
558: actually succeeds.
559: * The man(7) parser now supports the PD macro (paragraph distance),
560: and (for GNU man-ext compatibility only) EX (example block) and EE
561: (example end). Plus several bugfixes regarding indentation, line
562: breaks, and vertical spacing, and regarding RS following TP.
563: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
564: the \z (zero cursor advance) escape and the cc (change control
565: character) and it (input line trap) requests. Plus bugfixes regarding
566: the \t (tab) escape, nested escape sequences, and conditional requests.
567: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
568: enclosures, delimiter handling, list indentation and horizontal and
569: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
570: bugfixes related to the handling of syntax errors like badly nested
571: font blocks, stray Ta macros outside column lists, unterminated It Xo
572: blocks, and non-text children of Nm blocks.
573: * In tbl(7), the width of horizontal spans and the vertical spacing
574: around tables was corrected, and in man(7) files, a crash was fixed
575: that was triggered by some particular unclosed T{ macros.
576: * For mandoc developers, we now provide a tbl(3) library manual and
577: gmdiff, a very small, very simplistic groff-versus-mandoc output
578: comparison tool.
1.2 schwarze 579: * Provide this NEWS file.
1.1 schwarze 580:
581: Changes in version 1.12.1, released on March 23, 2012
582:
583: * Significant work on apropos(1) and mandocdb(8). These tools are now
584: much more robust. A whatis(1) implementation is now handled as an
585: apropos(1) mode. These tools are also able to minimally handle
586: pre-formatted pages, that is, those already formatted by another
587: utility such as GNU troff.
588: * The man.cgi(7) script is also now available for wider testing.
589: It interfaces with mandocdb(8) manuals cached by catman(8).
590: HTML output is generated on-the-fly by libmandoc or internal
591: methods to convert pre-formatted pages.
592: * The mailing list archive for the discuss and tech lists are being
593: hosted by Gmane at gmane.comp.tools.mdocml.user and
594: gmane.comp.tools.mdocml.devel, respectively.
595:
596: Changes in version 1.12.0, released on October 8, 2011
597:
598: * This version features a new, work-in-progress mandoc(1) output mode:
599: -Tman. This mode allows a system maintainer to distribute man(7)
600: media for older systems that may not natively support mdoc(7), such
601: as old Solaris systems.
602: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
603: * While adding features, an apropos(1) utility has been merged from the
604: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
605: search of manual content. apropos(1) is different from the traditional
606: apropos primarily in allowing keyword search (such as for functions,
607: utilities, etc.) and regular expressions. Note that the calling
608: syntax for apropos is likely to change as it settles down.
609: * In documentation news, the mdoc(7) and man(7) manuals have been
610: made considerably more readable by adding MACRO OVERVIEW sections, by
611: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
612: and by moving the very technical MACRO SYNTAX sections down to the
613: bottom of the page.
614: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
615: was rewritten completely. It is now compatible with groff(1), both
616: with and without frames and rulers.
617: * Nesting of indented blocks is now supported in man(7), and several
618: bugs were fixed regarding indentation and alignment.
619: * The page headers in mdoc(7) are now nicer for very long titles.
620:
621: Changes in version 1.11.7, released on September 2, 2011
622:
623: * Added demandoc(1) utility for stripping away macros and escapes.
624: This replaces the historical deroff(1) utility.
625: * Also improved the mdoc(7) and man(7) manuals.
626:
627: Changes in version 1.11.6, released on August 16, 2011
628:
629: * Handling of tr macro in roff(7) implemented. This makes Perl
630: documentation much more readable. Hyphenation is also now enabled in
631: man(7) format documents. Many other general improvements have been
632: implemented.
633:
634: Changes in version 1.11.5, released on July 24, 2011
635:
636: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
637: input (although few GNU extensions are accepted, nor is mixing
638: low-level roff with eqn). See the eqn(7) manual for details.
639: For the time being, equations are rendered as simple in-line text.
640: The equation parser satisfies the language specified in the
641: Second Edition User's Guide:
642: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
643:
644: Changes in version 1.11.4, released on July 12, 2011
645:
646: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
647: and the man(7) parser. This release was significantly assisted by
648: participants in OpenBSD's c2k11. Thanks!
649:
650: Changes in version 1.11.3, released on May 26, 2011
651:
652: * Introduce locale-encoding of output with the -Tlocale output option and
653: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
654: respectively, for details. This allows for non-ASCII characters (e.g.,
655: \[u5000]) to be rendered in the locale's encoding, if said environment
656: supports wide-character encoding (if it does not, -Tascii is used
657: instead). Locale support can be turned off at compile time by removing
658: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
659: for -Tascii.
660: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
661: be on-the-fly recoded into mandoc(1) input by using the newly-added
662: preconv(1) utility. Note: in the future, this feature may be
663: integrated into mandoc(1).
664:
665: Changes in version 1.11.2, released on May 12, 2011
666:
667: * Corrected some installation issues in version 1.11.1.
668: * Further migration to libmandoc.
669: * Initial public release (this utility is very much under development)
670: of mandocdb(8). This utility produces keyword databases of manual
671: content, which features semantic querying of manual content.
672:
673: Changes in version 1.11.1, released on April 4, 2011
674:
675: * The earlier libroff, libmdoc, and libman soup have been merged into
676: a single library, libmandoc, which manages all aspects of parsing
677: real manuals, from line-handling to tbl(7) parsing.
678: * As usual, many general fixes and improvements have also occurred.
679: In particular, a great deal of redundancy and superfluous code has
680: been removed with the merging of the backend libraries.
1.3 schwarze 681: * see also the changes in 1.10.10
682:
683: Changes in version 1.10.10, March 20, 2011, NOT released
684:
685: * Initial eqn(7) functionality is in place. For the time being,
686: this is limited to the recognition of equation blocks;
687: future version of mdocml will expand upon this framework.
1.1 schwarze 688:
689: Changes in version 1.10.9, released on January 7, 2011
690:
691: * Many back-end fixes have been implemented: argument handling (quoting),
692: man(7) improvements, error/warning classes, and many more.
693: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
694: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
695: minimal, especially for -Thtml and -Txhtml, but manages to at least
696: display data. This means that mandoc(1) now has built-in support
697: for two troff preprocessors via libroff: soelim(1) and tbl(1).
698:
699: Changes in version 1.10.8, released on December 24, 2010
700:
1.3 schwarze 701: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 702: readable output in arbitrary browsers, including text-based ones like
703: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
704: for examples. Attention: available style-sheet classes have been
705: considerably changed! See the example.style.css file for details.
706: Lastly, libmdoc and libman have been cleaned up and reduced in size
707: and complexity.
1.3 schwarze 708: * see also the changes in 1.10.7
709:
710: Changes in version 1.10.7, December 6, 2010, NOT released
711:
712: Significant improvements merged from OpenBSD downstream, including:
713: * many new roff(7) components,
714: * in-line implementation of troff's soelim(1),
715: * broken-block handling,
716: * overhauled error classifications, and
717: * cleaned up handling of error conditions.
1.1 schwarze 718:
719: Changes in version 1.10.6, released on September 27, 2010
720:
721: * Calling conventions for mandoc(1) have changed: -W improved and -f
722: deprecated.
723: * Non-ASCII characters are also now uniformly discarded.
724: * Lots of documentation improvements.
725: * Many incremental fixes accomodating for groff's more interesting
726: productions.
727: * Lastly, pod2man(1) preambles are now fully accepted after some
728: considerable roff(7) and special character support.
729:
730: Changes in version 1.10.5, released on July 27, 2010
731:
732: * Primarily a bug-fix and polish release, but including -Tpdf support
733: in mandoc(1) by way of "Summer of Code". Highlights:
734: * fix "Sm" and "Bd" handling
735: * fix end-of-sentence handling for embedded sentences
736: * polish man(7) documentation
737: * document all mdoc(7) macros
738: * polish mandoc(1) -Tps output
739: * lots of internal clean-ups in character escapes
740: * un-break literal contexts in man(7) documents
741: * improve -Thtml output for -man
742: * add mandoc(1) -Tpdf support
743:
744: Changes in version 1.10.4, released on July 12, 2010
745:
746: * Lots of features developed during both "Summer of Code" and the
747: OpenBSD c2k10 hackathon:
748: * minimal "ds" roff(7) symbols are supported
749: * beautified SYNOPSIS section output
750: * acceptance of scope-block breakage in mdoc(7)
751: * clarify error message status
752: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 753: * see also changes in 1.10.3
754:
755: Changes in version 1.10.3, June 29, 2010, NOT released
756:
757: * variable font-width and paper-size support in mandoc(1) -Tps output
758: * "Bk" mdoc(7) support
1.1 schwarze 759:
760: Changes in version 1.10.2, released on June 19, 2010
761:
762: * Small release featuring text-decoration in -Tps output,
763: a few minor relaxations of errors, and some optimisations.
764:
765: Changes in version 1.10.1, released on June 7, 2010
766:
767: * This primarily focusses on the "Bl" and "It" macros described in
768: mdoc(7). Multi-line column support is now fully compatible with groff,
769: as are implicit list entries for columns.
770: * Removed manuals(7) in favour of http://manpages.bsd.lv.
771: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
772: in MANUAL STRUCTURE) has also been considerably simplified compared
773: to groff's method.
774: * Furthermore, the -Owidth=width output option has been added to -Tascii,
775: see mandoc(1).
776: * Lastly, initial PostScript output has been added with the -Tps option
777: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
778: font decorations.
779:
780: Changes in version 1.10.0, released on May 29, 2010
781:
782: * Release consisting of the results from the m2k10 hackathon and up-merge
783: from OpenBSD. This requires a significant note of thanks to Ingo
784: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
785: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
786: Ingo's m2k10 report) follow in no particular order:
787: * a libroff preprocessor in front of libmdoc and libman stripping out
788: roff(7) instructions;
789: * end-of-sentence (EOS) detection in free-form and macro lines;
790: * correct handling of tab-separated columnar lists in mdoc(7);
791: * improved main calling routines to optionally use mmap(3) for better
792: performance;
793: * cleaned up exiting when invoked as -Tlint or over multiple files
794: with -fign-errors;
795: * error and warning message handling re-written to be unified for
796: libroff, libmdoc, and libman;
797: * handling of badly-nested explicit-scoped macros;
798: * improved free-form text parsing in libman and libmdoc;
799: * significant GNU troff compatibility improvements in -Tascii,
800: largely in terms of spacing;
801: * a regression framework for making sure the many fragilities of GNU
802: troff aren't trampled in subsequent work;
803: * support for -Tascii breaking at hyphens encountered in free-form text;
804: * and many more minor fixes and improvements
805:
806: Changes in version 1.9.25, released on May 13, 2010
807:
808: * Fixed handling of "\*(Ba" escape.
809: * Backed out -fno-ign-chars (pointless complexity).
810: * Fixed erroneous breaking of literal lines.
811: * Fixed SYNOPSIS breaking lines before non-initial macros.
812: * Changed default section ordering.
813: * Most importantly, the framework for end-of-sentence double-spacing is
814: in place, now implemented for the "end-of-sentence, end-of-line" rule.
815: * This is a stable roll-back point before the mandoc hackathon in Rostock!
816:
817: Changes in version 1.9.24, released on May 9, 2010
818:
819: * Rolled back break-at-hyphen.
820: * -DUGLY is now the default (no feature splits!).
821: * Free-form text is not de-chunked any more: lines are passed
822: whole-sale into the front-end, including whitespace.
823: * Added mailing lists.
824:
825: Changes in version 1.9.23, released on April 7, 2010
826:
827: * mdocml has been linked to the OpenBSD build.
828: * This version incorporates many small changes, mostly from patches
829: by OpenBSD, allowing crufty manuals to slip by with warnings instead
830: of erroring-out.
831: * Some subtle semantic issues, such as punctuation scope, have also
832: been fixed.
833: * Lastly, some issues with -Thtml have been fixed, which prompted an
834: update to the online manual pages style layout.
835:
836: Changes in version 1.9.22, released on March 31, 2010
837:
838: * Adjusted merge of the significant work by Ingo Schwarze
839: in getting "Xo" blocks (block full implicit, e.g., "It"
840: for non-columnar lists) to work properly. This isn't
841: enabled by default: you must specify -DUGLY as a compiler
842: flag (see the Makefile for details).
843:
844: Changes in version 1.9.20, released on March 30, 2010
845:
846: * More efforts to get roff instructions in man(7) documents under
847: control. Note that roff instructions embedded in line-scoped,
848: next-line macros (e.g. "B") are not supported.
849: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
850: are now correctly handled.
851:
852: Changes in version 1.9.18, released on March 27, 2010
853:
854: * Many fixes (largely pertaining to scope)
855: and improvements (e.g., handling of apostrophe-control macros,
856: which fixes the strange "BR" seen in some macro output)
857: to handling roff instructions in man(7) documents.
858:
859: Changes in version 1.9.17, released on March 25, 2010
860:
861: * Accept perlpod(1) standard preamble.
862: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
863: roff macro blocks.
864:
865: Changes in version 1.9.16, released on March 22, 2010
866:
867: * Inspired by patches and bug reports by Ingo Schwarze,
868: allowed man(7) to accept non-printing elements to be nested
869: within next-line scopes, such as "br" within "B" or "TH",
870: which is valid roff.
871: * Longsoon architecture also noted and Makefile cleaned up.
872:
873: Changes in version 1.9.15, released on February 18, 2010
874:
875: * Moved to our new BSD.lv home.
876: * XHTML is now an acceptable output mode for mandoc(1);
877: * "Xr" made more compatible with groff;
878: * "Vt" fixed when invoked in SYNOPSIS;
879: * "\\" escape removed;
880: * end-of-line white-space detected for all lines;
881: * subtle bug fixed in list display for some modes;
882: * compatibility layer checked in for compilation in diverse
883: UNIX systems;
884: * and column lengths handled correctly.
