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.

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

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.

1.17 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.
1.20 ! schwarze 68: * mdoc(7): Fix an assertion failure that happened for some .Bl -column
! 69: lists containing a column width of "-4n", "-3n", or "-2n".
1.13 schwarze 70: * mdoc(7): Fix an assertion failure caused by .Bl -column without .It
71: but containing eqn(7) or tbl(7) code.

443:
444: --- MAJOR NEW FEATURES ---
445: * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite
446: based on SQLite3 is now included.
447: * The roff(7) parser now provides an almost complete implementation
448: of numerical expressions.
449: * Warning and error messages have been improved in many ways.
450: Almost all fatal errors were downgraded to normal errors and some
451: even to warnings. Almost all messages now mention the macro where
452: the issue is detected and many indicate the workaround employed.
453: The mandoc(1) manual now includes a list explaining all messages.
454: --- MINOR NEW FEATURES ---
455: * The roff(7) parser now supports the .ami (append to macro with
456: indirectly specified name), .as (append to user-defined
457: string), .dei (define macro with indirectly specified name),
458: .ll (line length), and .rr (remove register) requests.
459: * The roff(7) parser now supports string comparison and numerical
460: conditionals in the .if and .ie requests.
461: * The roff parser now fully supports the \B (validate numerical
462: expression) and partially supports the \w (measure text width)
463: escape sequences.
464: * The terminal formatter now supports the \: (optional line break)
465: escape sequence.
466: * The roff parser now supports expansion of user-defined strings
467: involving indirect references.
468: * The roff(7) parser now handles some pre-defined read-only
469: number registers that occur in the pod2man(1) preamble.
470: * For backward compatibility, the mdoc(7) parser and formatters
471: now support the obsolete macros .En, .Es, .Fr, and .Ot.
472: * The mdoc(7) formatter non partially supports .Bd -centered.
473: * tbl(7) now handles leading and trailing vertical lines.
474: * The build system now provides fallback versions of strcasestr(3)
475: and strsep(3) for systems lacking them.
476: * The mdoc(7) manual now explains how various standards
477: supported by the .St macro are related to each other.
478: --- BUGFIXES ---
479: * In the roff(7) parser, several bugs were fixed with respect
480: to closing conditional blocks on macro lines.
481: * Parsing of roff(7) identifiers and escape sequences was improved
482: in multiple respects.
483: * In the mdoc(7) parser, the handling of defective document
484: prologues was improved in multiple ways.
485: * The mdoc(7) parser no longer skips content before the first section
486: header, and it no longer deletes non-.% content from .Rs blocks.
487: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
488: * In the mdoc(7) parser, handling of .Sm with missing or invalid
489: arguments was corrected.
490: * In the mdoc(7) parser, trailing punctuation at the end of partial
491: implicit macros no longer triggers end-of-sentence spacing.
492: * In the terminal formatter, two crashes were fixed: one triggered by
493: excessive indentation and another by excessively long .Nm arguments.
494: * In the terminal formatter, a floating point rounding bug was
495: fixed that sometimes caused an off-by-one error in indentation.
496: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
497: and non-breakable spaces was corrected.
498: * In the HTML formatter, encoding of special characters was
499: corrected in multiple respects.
500: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
501: improved for various edge cases.
502: * In the mdoc(7) formatter, handling of empty .Bl -inset item
503: heads was improved.
504: * In the man(7) formatter, some bugs were fixed with respect
505: to same-line detection in the context of .TP and .nf macros,
506: and the indentation of .IP and .TP blocks was improved.
507: * The mandoc(3) library no longer prints to stderr.

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