1.1 schwarze 2:
3: This file lists the most important changes in the mdocml.bsd.lv distribution.
1.13 schwarze 4:
1.14 schwarze 5: Changes in version 1.14.1, released on February XXX, 2017
1.13 schwarze 6:
7: --- MAJOR NEW FEATURES ---
8: * apropos(1): Reimplement complete semantic search functionality
9: without the dependency on SQLite3, using only POSIX APIs.
10: This comes with a completely new mandoc.db(5) file format.
11: * man(1): Support more than one tag entry for the same search term,
12: plus some minor improvements to the less(1) :t support.
13: * -Thtml: Use real macro names for CSS classes.
14: Systematic cleanup of and many improvements to mandoc.css.
15: * -Thtml: Produce human readable HTML code by using indentation
16: and better line breaks. Improve various HTML elements,
17: and trim several useless ones.
18: * New catman(8) utility, still somewhat experimental.
1.14 schwarze 19: * Now includes a portable version of the OpenBSD mandoc regression
20: suite, see regress/regress.pl.1 for details.
1.13 schwarze 21: --- REMOVED FUNCTIONALITY ---
22: * Operating systems that don't provide mmap(3) are no longer supported.
23: * Drop support for manpath(1). Even if your system has manpath(1),
24: it is simpler to use MANPATH_DEFAULT in configure.local for
25: operating system defaults, man.conf(5) for machine-specific
26: modifications, and ${MANPATH}, -m, and -M for user preferences
27: than to bother with the complexity of manpath(1).
28: * makewhatis(8) -p: No longer warn about missing MLINKS since these
29: are no longer needed for anything.
30: --- MINOR NEW FEATURES ---
31: * mdoc(7): Warn about invalid punctuation and content below NAME.
32: * mdoc(7): Warn about .Xr lacking the second argument (section).

34: * roff(7): Warn about trailing whitespace at the end of comments.
35: * mdoc(7): Always do text production in the validator, never in the
36: formatters. Cleaner, simpler, shorter, helps NetBSD apropos(1)
37: and also makes -Ttree output more useful.
1.15 schwarze 38: * -Ttree: Show metadata and some additional node flags.
39: New -Onoval output option to show the unvalidated tree.
1.13 schwarze 40: --- RELIABILITY BUGFIXES ---
41: * man(1): Make "man -l" work with standard input from a pipe or file,
42: as long as standard output is a terminal.
43: * mdoc(7): Fix out of bounds read access for .Bl without a type
44: but with a width.
45: * mdoc(7): Fix out of bounds read access for .Bl -column starting
46: with a tab character instead of a child .It macro.

48: by stray block end macros in nested blocks of mismatching type.
49: * man(1): Fix NULL dereference when the first of multiple pages
50: shown was preformatted.
1.18 schwarze 51: * mdoc(7): Fix syntax tree corruption leading to NULL dereference
52: caused by partial implicit macros inside .Bl -column table cells.
1.13 schwarze 53: * mdoc(7): Fix syntax tree corruption leading to NULL dereference
54: for macro sequences like .Bl .Bl .It Bo .El .It.
1.15 schwarze 55: * mdoc(7): Fix syntax tree corruption leading to NULL dereference
1.13 schwarze 56: caused by .Ta following a nested .Bl -column breaking another block.
1.16 schwarze 57: * mdoc(7): Fix syntax tree corruption sometimes leading to NULL
1.17 schwarze 58: dereference caused by indirectly broken .Nd or .Nm blocks.
1.13 schwarze 59: * mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns.
1.17 schwarze 60: * mdoc(7): Fix NULL dereference in some specific cases of a
61: block-end macro calling another block-end macro.
1.13 schwarze 62: * mdoc(7): Fix NULL dereference if the only child of the head
63: of the first .Sh was an empty in-line macro.
1.19 ! schwarze 64: * eqn(7): Fix NULL dereference in the terminal formatter
! 65: for empty matrices and empty square roots.
1.13 schwarze 66: * mdoc(7): Fix an assertion failure for a .Bd without a type that
67: breaks another block.
68: * mdoc(7): Fix an assertion failure caused by .Bl -column without .It
69: but containing eqn(7) or tbl(7) code.
70: * roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf.
71: * roff(7): Fix an assertion failures caused by whitespace inside \o''
72: (overstrike) sequences.

467: number registers that occur in the pod2man(1) preamble.
468: * For backward compatibility, the mdoc(7) parser and formatters
469: now support the obsolete macros .En, .Es, .Fr, and .Ot.
470: * The mdoc(7) formatter non partially supports .Bd -centered.
471: * tbl(7) now handles leading and trailing vertical lines.
472: * The build system now provides fallback versions of strcasestr(3)
473: and strsep(3) for systems lacking them.

475: supported by the .St macro are related to each other.
476: --- BUGFIXES ---
477: * In the roff(7) parser, several bugs were fixed with respect
478: to closing conditional blocks on macro lines.
479: * Parsing of roff(7) identifiers and escape sequences was improved
480: in multiple respects.
481: * In the mdoc(7) parser, the handling of defective document
482: prologues was improved in multiple ways.
483: * The mdoc(7) parser no longer skips content before the first section
484: header, and it no longer deletes non-.% content from .Rs blocks.
485: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
486: * In the mdoc(7) parser, handling of .Sm with missing or invalid
487: arguments was corrected.
488: * In the mdoc(7) parser, trailing punctuation at the end of partial
489: implicit macros no longer triggers end-of-sentence spacing.
490: * In the terminal formatter, two crashes were fixed: one triggered by
491: excessive indentation and another by excessively long .Nm arguments.
492: * In the terminal formatter, a floating point rounding bug was
493: fixed that sometimes caused an off-by-one error in indentation.
494: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
495: and non-breakable spaces was corrected.
496: * In the HTML formatter, encoding of special characters was
497: corrected in multiple respects.
498: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
499: improved for various edge cases.
500: * In the mdoc(7) formatter, handling of empty .Bl -inset item
501: heads was improved.
502: * In the man(7) formatter, some bugs were fixed with respect
503: to same-line detection in the context of .TP and .nf macros,
504: and the indentation of .IP and .TP blocks was improved.
505: * The mandoc(3) library no longer prints to stderr.

517: Changes in version 1.12.3, released on December 31, 2013
518:
519: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
520: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
521: Thanks to Franco Fichtner for doing part of the work.
522: * The mdoc(7) .Bk macro got some addititonal bugfixes.
523: * In mdoc(7) macro arguments, double quotes can now be quoted
524: by doubling them, just like in man(7).
525: Thanks to Tsugutomo ENAMI for the patch.
526: * At the end of man(7) macro lines, end-of-sentence spacing
527: now works. Thanks to Franco Fichtner for the patch.
528: * For backward compatibility, the man(7) parser now supports the
529: man-ext .UR/.UE (uniform resource identifier) block macros.
530: * The man(7) parser now handles closing blocks that are not open
531: more gracefully.
532: * The man(7) parser now ignores blank lines right after .SH and .SS.
533: * In the man(7) formatter, reset indentation when leaving a block,
534: not just when entering the next one.
535: * The roff(7) .nr request now supports incrementing and decrementing
536: number registers and stops parsing the number right before the
537: first non-digit character.
538: * The roff(7) parser now supports the alternative escape sequence
539: syntax \C'uXXXX' for Unicode characters.
540: * The roff(7) parser now parses and ignores the .fam (font family)
541: and .hw (hyphenation points) requests and the \d and \u escape
542: sequences.
543: * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
1.1 schwarze 544:
1.2 schwarze 545: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 546:
547: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
548: is now fully functional.
549: * The mandoc(1) utility now supports the -Ios (default operating system)
550: input option, and the -Tutf8 output mode now actually works.
551: * The mandocdb(8) utility no longer truncates existing databases when
552: starting to build new ones, but only replaces them when the build
553: actually succeeds.
554: * The man(7) parser now supports the PD macro (paragraph distance),
555: and (for GNU man-ext compatibility only) EX (example block) and EE
556: (example end). Plus several bugfixes regarding indentation, line
557: breaks, and vertical spacing, and regarding RS following TP.
558: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
559: the \z (zero cursor advance) escape and the cc (change control
560: character) and it (input line trap) requests. Plus bugfixes regarding
561: the \t (tab) escape, nested escape sequences, and conditional requests.
562: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
563: enclosures, delimiter handling, list indentation and horizontal and
564: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
565: bugfixes related to the handling of syntax errors like badly nested
566: font blocks, stray Ta macros outside column lists, unterminated It Xo
567: blocks, and non-text children of Nm blocks.
568: * In tbl(7), the width of horizontal spans and the vertical spacing
569: around tables was corrected, and in man(7) files, a crash was fixed
570: that was triggered by some particular unclosed T{ macros.
571: * For mandoc developers, we now provide a tbl(3) library manual and
572: gmdiff, a very small, very simplistic groff-versus-mandoc output
573: comparison tool.
1.2 schwarze 574: * Provide this NEWS file.
1.1 schwarze 575:
576: Changes in version 1.12.1, released on March 23, 2012
577:
578: * Significant work on apropos(1) and mandocdb(8). These tools are now
579: much more robust. A whatis(1) implementation is now handled as an
580: apropos(1) mode. These tools are also able to minimally handle
581: pre-formatted pages, that is, those already formatted by another
582: utility such as GNU troff.
583: * The man.cgi(7) script is also now available for wider testing.
584: It interfaces with mandocdb(8) manuals cached by catman(8).
585: HTML output is generated on-the-fly by libmandoc or internal
586: methods to convert pre-formatted pages.
587: * The mailing list archive for the discuss and tech lists are being
588: hosted by Gmane at gmane.comp.tools.mdocml.user and
589: gmane.comp.tools.mdocml.devel, respectively.
590:
591: Changes in version 1.12.0, released on October 8, 2011
592:
593: * This version features a new, work-in-progress mandoc(1) output mode:
594: -Tman. This mode allows a system maintainer to distribute man(7)
595: media for older systems that may not natively support mdoc(7), such
596: as old Solaris systems.
597: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
598: * While adding features, an apropos(1) utility has been merged from the
599: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
600: search of manual content. apropos(1) is different from the traditional
601: apropos primarily in allowing keyword search (such as for functions,
602: utilities, etc.) and regular expressions. Note that the calling
603: syntax for apropos is likely to change as it settles down.
604: * In documentation news, the mdoc(7) and man(7) manuals have been
605: made considerably more readable by adding MACRO OVERVIEW sections, by
606: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
607: and by moving the very technical MACRO SYNTAX sections down to the
608: bottom of the page.
609: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
610: was rewritten completely. It is now compatible with groff(1), both
611: with and without frames and rulers.
612: * Nesting of indented blocks is now supported in man(7), and several
613: bugs were fixed regarding indentation and alignment.
614: * The page headers in mdoc(7) are now nicer for very long titles.
615:
616: Changes in version 1.11.7, released on September 2, 2011
617:
618: * Added demandoc(1) utility for stripping away macros and escapes.
619: This replaces the historical deroff(1) utility.
620: * Also improved the mdoc(7) and man(7) manuals.
621:
622: Changes in version 1.11.6, released on August 16, 2011
623:
624: * Handling of tr macro in roff(7) implemented. This makes Perl
625: documentation much more readable. Hyphenation is also now enabled in
626: man(7) format documents. Many other general improvements have been
627: implemented.
628:
629: Changes in version 1.11.5, released on July 24, 2011
630:
631: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
632: input (although few GNU extensions are accepted, nor is mixing
633: low-level roff with eqn). See the eqn(7) manual for details.
634: For the time being, equations are rendered as simple in-line text.
635: The equation parser satisfies the language specified in the
636: Second Edition User's Guide:
637: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
638:
639: Changes in version 1.11.4, released on July 12, 2011
640:
641: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
642: and the man(7) parser. This release was significantly assisted by
643: participants in OpenBSD's c2k11. Thanks!
644:
645: Changes in version 1.11.3, released on May 26, 2011
646:
647: * Introduce locale-encoding of output with the -Tlocale output option and
648: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
649: respectively, for details. This allows for non-ASCII characters (e.g.,
650: \[u5000]) to be rendered in the locale's encoding, if said environment
651: supports wide-character encoding (if it does not, -Tascii is used
652: instead). Locale support can be turned off at compile time by removing
653: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
654: for -Tascii.
655: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
656: be on-the-fly recoded into mandoc(1) input by using the newly-added
657: preconv(1) utility. Note: in the future, this feature may be
658: integrated into mandoc(1).
659:
660: Changes in version 1.11.2, released on May 12, 2011
661:
662: * Corrected some installation issues in version 1.11.1.
663: * Further migration to libmandoc.
664: * Initial public release (this utility is very much under development)
665: of mandocdb(8). This utility produces keyword databases of manual
666: content, which features semantic querying of manual content.
667:
668: Changes in version 1.11.1, released on April 4, 2011
669:
670: * The earlier libroff, libmdoc, and libman soup have been merged into
671: a single library, libmandoc, which manages all aspects of parsing
672: real manuals, from line-handling to tbl(7) parsing.
673: * As usual, many general fixes and improvements have also occurred.
674: In particular, a great deal of redundancy and superfluous code has
675: been removed with the merging of the backend libraries.
1.3 schwarze 676: * see also the changes in 1.10.10
677:
678: Changes in version 1.10.10, March 20, 2011, NOT released
679:
680: * Initial eqn(7) functionality is in place. For the time being,
681: this is limited to the recognition of equation blocks;
682: future version of mdocml will expand upon this framework.
1.1 schwarze 683:
684: Changes in version 1.10.9, released on January 7, 2011
685:
686: * Many back-end fixes have been implemented: argument handling (quoting),
687: man(7) improvements, error/warning classes, and many more.
688: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
689: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
690: minimal, especially for -Thtml and -Txhtml, but manages to at least
691: display data. This means that mandoc(1) now has built-in support
692: for two troff preprocessors via libroff: soelim(1) and tbl(1).
693:
694: Changes in version 1.10.8, released on December 24, 2010
695:
1.3 schwarze 696: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 697: readable output in arbitrary browsers, including text-based ones like
698: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
699: for examples. Attention: available style-sheet classes have been
700: considerably changed! See the example.style.css file for details.
701: Lastly, libmdoc and libman have been cleaned up and reduced in size
702: and complexity.
1.3 schwarze 703: * see also the changes in 1.10.7
704:
705: Changes in version 1.10.7, December 6, 2010, NOT released
706:
707: Significant improvements merged from OpenBSD downstream, including:
708: * many new roff(7) components,
709: * in-line implementation of troff's soelim(1),
710: * broken-block handling,
711: * overhauled error classifications, and
712: * cleaned up handling of error conditions.
1.1 schwarze 713:
714: Changes in version 1.10.6, released on September 27, 2010
715:
716: * Calling conventions for mandoc(1) have changed: -W improved and -f
717: deprecated.
718: * Non-ASCII characters are also now uniformly discarded.
719: * Lots of documentation improvements.
720: * Many incremental fixes accomodating for groff's more interesting
721: productions.
722: * Lastly, pod2man(1) preambles are now fully accepted after some
723: considerable roff(7) and special character support.
724:
725: Changes in version 1.10.5, released on July 27, 2010
726:
727: * Primarily a bug-fix and polish release, but including -Tpdf support
728: in mandoc(1) by way of "Summer of Code". Highlights:
729: * fix "Sm" and "Bd" handling
730: * fix end-of-sentence handling for embedded sentences
731: * polish man(7) documentation
732: * document all mdoc(7) macros
733: * polish mandoc(1) -Tps output
734: * lots of internal clean-ups in character escapes
735: * un-break literal contexts in man(7) documents
736: * improve -Thtml output for -man
737: * add mandoc(1) -Tpdf support
738:
739: Changes in version 1.10.4, released on July 12, 2010
740:
741: * Lots of features developed during both "Summer of Code" and the
742: OpenBSD c2k10 hackathon:
743: * minimal "ds" roff(7) symbols are supported
744: * beautified SYNOPSIS section output
745: * acceptance of scope-block breakage in mdoc(7)
746: * clarify error message status
747: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 748: * see also changes in 1.10.3
749:
750: Changes in version 1.10.3, June 29, 2010, NOT released
751:
752: * variable font-width and paper-size support in mandoc(1) -Tps output
753: * "Bk" mdoc(7) support
1.1 schwarze 754:
755: Changes in version 1.10.2, released on June 19, 2010
756:
757: * Small release featuring text-decoration in -Tps output,
758: a few minor relaxations of errors, and some optimisations.
759:
760: Changes in version 1.10.1, released on June 7, 2010
761:
762: * This primarily focusses on the "Bl" and "It" macros described in
763: mdoc(7). Multi-line column support is now fully compatible with groff,
764: as are implicit list entries for columns.
765: * Removed manuals(7) in favour of http://manpages.bsd.lv.
766: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
767: in MANUAL STRUCTURE) has also been considerably simplified compared
768: to groff's method.
769: * Furthermore, the -Owidth=width output option has been added to -Tascii,
770: see mandoc(1).
771: * Lastly, initial PostScript output has been added with the -Tps option
772: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
773: font decorations.
774:
775: Changes in version 1.10.0, released on May 29, 2010
776:
777: * Release consisting of the results from the m2k10 hackathon and up-merge
778: from OpenBSD. This requires a significant note of thanks to Ingo
779: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
780: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
781: Ingo's m2k10 report) follow in no particular order:
782: * a libroff preprocessor in front of libmdoc and libman stripping out
783: roff(7) instructions;
784: * end-of-sentence (EOS) detection in free-form and macro lines;
785: * correct handling of tab-separated columnar lists in mdoc(7);
786: * improved main calling routines to optionally use mmap(3) for better
787: performance;
788: * cleaned up exiting when invoked as -Tlint or over multiple files
789: with -fign-errors;
790: * error and warning message handling re-written to be unified for
791: libroff, libmdoc, and libman;
792: * handling of badly-nested explicit-scoped macros;
793: * improved free-form text parsing in libman and libmdoc;
794: * significant GNU troff compatibility improvements in -Tascii,
795: largely in terms of spacing;
796: * a regression framework for making sure the many fragilities of GNU
797: troff aren't trampled in subsequent work;
798: * support for -Tascii breaking at hyphens encountered in free-form text;
799: * and many more minor fixes and improvements
800:
801: Changes in version 1.9.25, released on May 13, 2010
802:
803: * Fixed handling of "\*(Ba" escape.
804: * Backed out -fno-ign-chars (pointless complexity).
805: * Fixed erroneous breaking of literal lines.
806: * Fixed SYNOPSIS breaking lines before non-initial macros.
807: * Changed default section ordering.
808: * Most importantly, the framework for end-of-sentence double-spacing is
809: in place, now implemented for the "end-of-sentence, end-of-line" rule.
810: * This is a stable roll-back point before the mandoc hackathon in Rostock!
811:
812: Changes in version 1.9.24, released on May 9, 2010
813:
814: * Rolled back break-at-hyphen.
815: * -DUGLY is now the default (no feature splits!).
816: * Free-form text is not de-chunked any more: lines are passed
817: whole-sale into the front-end, including whitespace.
818: * Added mailing lists.
819:
820: Changes in version 1.9.23, released on April 7, 2010
821:
822: * mdocml has been linked to the OpenBSD build.
823: * This version incorporates many small changes, mostly from patches
824: by OpenBSD, allowing crufty manuals to slip by with warnings instead
825: of erroring-out.
826: * Some subtle semantic issues, such as punctuation scope, have also
827: been fixed.
828: * Lastly, some issues with -Thtml have been fixed, which prompted an
829: update to the online manual pages style layout.
830:
831: Changes in version 1.9.22, released on March 31, 2010
832:
833: * Adjusted merge of the significant work by Ingo Schwarze
834: in getting "Xo" blocks (block full implicit, e.g., "It"
835: for non-columnar lists) to work properly. This isn't
836: enabled by default: you must specify -DUGLY as a compiler
837: flag (see the Makefile for details).
838:
839: Changes in version 1.9.20, released on March 30, 2010
840:
841: * More efforts to get roff instructions in man(7) documents under
842: control. Note that roff instructions embedded in line-scoped,
843: next-line macros (e.g. "B") are not supported.
844: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
845: are now correctly handled.
846:
847: Changes in version 1.9.18, released on March 27, 2010
848:
849: * Many fixes (largely pertaining to scope)
850: and improvements (e.g., handling of apostrophe-control macros,
851: which fixes the strange "BR" seen in some macro output)
852: to handling roff instructions in man(7) documents.
853:
854: Changes in version 1.9.17, released on March 25, 2010
855:
856: * Accept perlpod(1) standard preamble.
857: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
858: roff macro blocks.
859:
860: Changes in version 1.9.16, released on March 22, 2010
861:
862: * Inspired by patches and bug reports by Ingo Schwarze,
863: allowed man(7) to accept non-printing elements to be nested
864: within next-line scopes, such as "br" within "B" or "TH",
865: which is valid roff.
866: * Longsoon architecture also noted and Makefile cleaned up.
867:
868: Changes in version 1.9.15, released on February 18, 2010
869:
870: * Moved to our new BSD.lv home.
871: * XHTML is now an acceptable output mode for mandoc(1);
872: * "Xr" made more compatible with groff;
873: * "Vt" fixed when invoked in SYNOPSIS;
874: * "\\" escape removed;
875: * end-of-line white-space detected for all lines;
876: * subtle bug fixed in list display for some modes;
877: * compatibility layer checked in for compilation in diverse
878: UNIX systems;
879: * and column lengths handled correctly.
