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.
38: * mdoc(7), man(7): Show metadata in -Ttree output.
39: --- RELIABILITY BUGFIXES ---
40: * man(1): Make "man -l" work with standard input from a pipe or file,
41: as long as standard output is a terminal.
42: * mdoc(7): Fix out of bounds read access for .Bl without a type
43: but with a width.
44: * mdoc(7): Fix out of bounds read access for .Bl -column starting
45: with a tab character instead of a child .It macro.

47: by stray block end macros in nested blocks of mismatching type.
48: * man(1): Fix NULL dereference when the first of multiple pages
49: shown was preformatted.
50: * mdoc(7): Fix syntax tree corruption leading to NULL dereference
51: for macro sequences like .Bl .Bl .It Bo .El .It.
52: * mdoc(7): Fix syntax tree corruption leading to NULL dereference
53: caused by .Ta following a nested .Bl -column breaking another block.
54: * mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns.
55: * mdoc(7): Fix NULL dereference if the only child of the head
56: of the first .Sh was an empty in-line macro.
57: * mdoc(7): Fix an assertion failure for a .Bd without a type that
58: breaks another block.
59: * mdoc(7): Fix an assertion failure caused by .Bl -column without .It
60: but containing eqn(7) or tbl(7) code.
61: * roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf.
62: * roff(7): Fix an assertion failures caused by whitespace inside \o''
63: (overstrike) sequences.
64: * -Thtml: Fix an assertion failure caused by -Oman or -Oincludes of
65: excessive length.
66: --- PORTABILITY IMPROVEMENTS ---
67: * man(1): Do not mix stdio narrow and wide stream orientation
68: on stdout, which could cause output corruption on glibc.
69: * mandoc(1): Autodetect a suitable locale for -Tutf8 mode.
70: * Autodetect whether PATH_MAX is defined.
71: * Autodetect if nanosleep(3) needs -lrt.
72: * Put compiler arguments that may contain -l at the end.
73: --- MINOR BUGFIXES ---
74: * mdoc(7): Fix SYNOPSIS output if the first child of .Nm is a macro.
75: * mdoc(7) -Thtml: Improve formatting of .Bl -tag with short tags.
76: * man(7) -Thtml: Preserve whitespace in .nf (nofill) mode.
77: * mandoc(1): Error out on invalid output options on the command line.

446: string), .dei (define macro with indirectly specified name),
447: .ll (line length), and .rr (remove register) requests.
448: * The roff(7) parser now supports string comparison and numerical
449: conditionals in the .if and .ie requests.

451: expression) and partially supports the \w (measure text width)
452: escape sequences.
453: * The terminal formatter now supports the \: (optional line break)
454: escape sequence.
455: * The roff parser now supports expansion of user-defined strings
456: involving indirect references.
457: * The roff(7) parser now handles some pre-defined read-only
458: number registers that occur in the pod2man(1) preamble.
459: * For backward compatibility, the mdoc(7) parser and formatters
460: now support the obsolete macros .En, .Es, .Fr, and .Ot.
461: * The mdoc(7) formatter non partially supports .Bd -centered.
462: * tbl(7) now handles leading and trailing vertical lines.
463: * The build system now provides fallback versions of strcasestr(3)
464: and strsep(3) for systems lacking them.
465: * The mdoc(7) manual now explains how various standards
466: supported by the .St macro are related to each other.
467: --- BUGFIXES ---
468: * In the roff(7) parser, several bugs were fixed with respect
469: to closing conditional blocks on macro lines.
470: * Parsing of roff(7) identifiers and escape sequences was improved
471: in multiple respects.
472: * In the mdoc(7) parser, the handling of defective document
473: prologues was improved in multiple ways.
474: * The mdoc(7) parser no longer skips content before the first section
475: header, and it no longer deletes non-.% content from .Rs blocks.
476: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
477: * In the mdoc(7) parser, handling of .Sm with missing or invalid
478: arguments was corrected.
479: * In the mdoc(7) parser, trailing punctuation at the end of partial
480: implicit macros no longer triggers end-of-sentence spacing.
481: * In the terminal formatter, two crashes were fixed: one triggered by
482: excessive indentation and another by excessively long .Nm arguments.
483: * In the terminal formatter, a floating point rounding bug was
484: fixed that sometimes caused an off-by-one error in indentation.
485: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
486: and non-breakable spaces was corrected.
487: * In the HTML formatter, encoding of special characters was
488: corrected in multiple respects.
489: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
490: improved for various edge cases.
491: * In the mdoc(7) formatter, handling of empty .Bl -inset item
492: heads was improved.
493: * In the man(7) formatter, some bugs were fixed with respect
494: to same-line detection in the context of .TP and .nf macros,
495: and the indentation of .IP and .TP blocks was improved.
496: * The mandoc(3) library no longer prints to stderr.

1.4 schwarze 507:
508: Changes in version 1.12.3, released on December 31, 2013
509:
510: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
511: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
512: Thanks to Franco Fichtner for doing part of the work.
513: * The mdoc(7) .Bk macro got some addititonal bugfixes.
514: * In mdoc(7) macro arguments, double quotes can now be quoted
515: by doubling them, just like in man(7).
516: Thanks to Tsugutomo ENAMI for the patch.
517: * At the end of man(7) macro lines, end-of-sentence spacing
518: now works. Thanks to Franco Fichtner for the patch.
519: * For backward compatibility, the man(7) parser now supports the
520: man-ext .UR/.UE (uniform resource identifier) block macros.
521: * The man(7) parser now handles closing blocks that are not open
522: more gracefully.
523: * The man(7) parser now ignores blank lines right after .SH and .SS.
524: * In the man(7) formatter, reset indentation when leaving a block,
525: not just when entering the next one.
526: * The roff(7) .nr request now supports incrementing and decrementing
527: number registers and stops parsing the number right before the
528: first non-digit character.
529: * The roff(7) parser now supports the alternative escape sequence
530: syntax \C'uXXXX' for Unicode characters.
531: * The roff(7) parser now parses and ignores the .fam (font family)
532: and .hw (hyphenation points) requests and the \d and \u escape
533: sequences.
534: * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
1.1 schwarze 535:
1.2 schwarze 536: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 537:
538: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
539: is now fully functional.
540: * The mandoc(1) utility now supports the -Ios (default operating system)
541: input option, and the -Tutf8 output mode now actually works.
542: * The mandocdb(8) utility no longer truncates existing databases when
543: starting to build new ones, but only replaces them when the build
544: actually succeeds.
545: * The man(7) parser now supports the PD macro (paragraph distance),
546: and (for GNU man-ext compatibility only) EX (example block) and EE
547: (example end). Plus several bugfixes regarding indentation, line
548: breaks, and vertical spacing, and regarding RS following TP.
549: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
550: the \z (zero cursor advance) escape and the cc (change control
551: character) and it (input line trap) requests. Plus bugfixes regarding
552: the \t (tab) escape, nested escape sequences, and conditional requests.
553: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
554: enclosures, delimiter handling, list indentation and horizontal and
555: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
556: bugfixes related to the handling of syntax errors like badly nested
557: font blocks, stray Ta macros outside column lists, unterminated It Xo
558: blocks, and non-text children of Nm blocks.
559: * In tbl(7), the width of horizontal spans and the vertical spacing
560: around tables was corrected, and in man(7) files, a crash was fixed
561: that was triggered by some particular unclosed T{ macros.
562: * For mandoc developers, we now provide a tbl(3) library manual and
563: gmdiff, a very small, very simplistic groff-versus-mandoc output
564: comparison tool.
1.2 schwarze 565: * Provide this NEWS file.
1.1 schwarze 566:
567: Changes in version 1.12.1, released on March 23, 2012
568:
569: * Significant work on apropos(1) and mandocdb(8). These tools are now
570: much more robust. A whatis(1) implementation is now handled as an
571: apropos(1) mode. These tools are also able to minimally handle
572: pre-formatted pages, that is, those already formatted by another
573: utility such as GNU troff.
574: * The man.cgi(7) script is also now available for wider testing.
575: It interfaces with mandocdb(8) manuals cached by catman(8).
576: HTML output is generated on-the-fly by libmandoc or internal
577: methods to convert pre-formatted pages.
578: * The mailing list archive for the discuss and tech lists are being
579: hosted by Gmane at gmane.comp.tools.mdocml.user and
580: gmane.comp.tools.mdocml.devel, respectively.
581:
582: Changes in version 1.12.0, released on October 8, 2011
583:
584: * This version features a new, work-in-progress mandoc(1) output mode:
585: -Tman. This mode allows a system maintainer to distribute man(7)
586: media for older systems that may not natively support mdoc(7), such
587: as old Solaris systems.
588: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
589: * While adding features, an apropos(1) utility has been merged from the
590: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
591: search of manual content. apropos(1) is different from the traditional
592: apropos primarily in allowing keyword search (such as for functions,
593: utilities, etc.) and regular expressions. Note that the calling
594: syntax for apropos is likely to change as it settles down.
595: * In documentation news, the mdoc(7) and man(7) manuals have been
596: made considerably more readable by adding MACRO OVERVIEW sections, by
597: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
598: and by moving the very technical MACRO SYNTAX sections down to the
599: bottom of the page.
600: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
601: was rewritten completely. It is now compatible with groff(1), both
602: with and without frames and rulers.
603: * Nesting of indented blocks is now supported in man(7), and several
604: bugs were fixed regarding indentation and alignment.
605: * The page headers in mdoc(7) are now nicer for very long titles.
606:
607: Changes in version 1.11.7, released on September 2, 2011
608:
609: * Added demandoc(1) utility for stripping away macros and escapes.
610: This replaces the historical deroff(1) utility.
611: * Also improved the mdoc(7) and man(7) manuals.
612:
613: Changes in version 1.11.6, released on August 16, 2011
614:
615: * Handling of tr macro in roff(7) implemented. This makes Perl
616: documentation much more readable. Hyphenation is also now enabled in
617: man(7) format documents. Many other general improvements have been
618: implemented.
619:
620: Changes in version 1.11.5, released on July 24, 2011
621:
622: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
623: input (although few GNU extensions are accepted, nor is mixing
624: low-level roff with eqn). See the eqn(7) manual for details.
625: For the time being, equations are rendered as simple in-line text.
626: The equation parser satisfies the language specified in the
627: Second Edition User's Guide:
628: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
629:
630: Changes in version 1.11.4, released on July 12, 2011
631:
632: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
633: and the man(7) parser. This release was significantly assisted by
634: participants in OpenBSD's c2k11. Thanks!
635:
636: Changes in version 1.11.3, released on May 26, 2011
637:
638: * Introduce locale-encoding of output with the -Tlocale output option and
639: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
640: respectively, for details. This allows for non-ASCII characters (e.g.,
641: \[u5000]) to be rendered in the locale's encoding, if said environment
642: supports wide-character encoding (if it does not, -Tascii is used
643: instead). Locale support can be turned off at compile time by removing
644: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
645: for -Tascii.
646: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
647: be on-the-fly recoded into mandoc(1) input by using the newly-added
648: preconv(1) utility. Note: in the future, this feature may be
649: integrated into mandoc(1).
650:
651: Changes in version 1.11.2, released on May 12, 2011
652:
653: * Corrected some installation issues in version 1.11.1.
654: * Further migration to libmandoc.
655: * Initial public release (this utility is very much under development)
656: of mandocdb(8). This utility produces keyword databases of manual
657: content, which features semantic querying of manual content.
658:
659: Changes in version 1.11.1, released on April 4, 2011
660:
661: * The earlier libroff, libmdoc, and libman soup have been merged into
662: a single library, libmandoc, which manages all aspects of parsing
663: real manuals, from line-handling to tbl(7) parsing.
664: * As usual, many general fixes and improvements have also occurred.
665: In particular, a great deal of redundancy and superfluous code has
666: been removed with the merging of the backend libraries.
1.3 schwarze 667: * see also the changes in 1.10.10
668:
669: Changes in version 1.10.10, March 20, 2011, NOT released
670:
671: * Initial eqn(7) functionality is in place. For the time being,
672: this is limited to the recognition of equation blocks;
673: future version of mdocml will expand upon this framework.
1.1 schwarze 674:
675: Changes in version 1.10.9, released on January 7, 2011
676:
677: * Many back-end fixes have been implemented: argument handling (quoting),
678: man(7) improvements, error/warning classes, and many more.
679: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
680: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
681: minimal, especially for -Thtml and -Txhtml, but manages to at least
682: display data. This means that mandoc(1) now has built-in support
683: for two troff preprocessors via libroff: soelim(1) and tbl(1).
684:
685: Changes in version 1.10.8, released on December 24, 2010
686:
1.3 schwarze 687: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 688: readable output in arbitrary browsers, including text-based ones like
689: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
690: for examples. Attention: available style-sheet classes have been
691: considerably changed! See the example.style.css file for details.
692: Lastly, libmdoc and libman have been cleaned up and reduced in size
693: and complexity.
1.3 schwarze 694: * see also the changes in 1.10.7
695:
696: Changes in version 1.10.7, December 6, 2010, NOT released
697:
698: Significant improvements merged from OpenBSD downstream, including:
699: * many new roff(7) components,
700: * in-line implementation of troff's soelim(1),
701: * broken-block handling,
702: * overhauled error classifications, and
703: * cleaned up handling of error conditions.
1.1 schwarze 704:
705: Changes in version 1.10.6, released on September 27, 2010
706:
707: * Calling conventions for mandoc(1) have changed: -W improved and -f
708: deprecated.
709: * Non-ASCII characters are also now uniformly discarded.
710: * Lots of documentation improvements.
711: * Many incremental fixes accomodating for groff's more interesting
712: productions.
713: * Lastly, pod2man(1) preambles are now fully accepted after some
714: considerable roff(7) and special character support.
715:
716: Changes in version 1.10.5, released on July 27, 2010
717:
718: * Primarily a bug-fix and polish release, but including -Tpdf support
719: in mandoc(1) by way of "Summer of Code". Highlights:
720: * fix "Sm" and "Bd" handling
721: * fix end-of-sentence handling for embedded sentences
722: * polish man(7) documentation
723: * document all mdoc(7) macros
724: * polish mandoc(1) -Tps output
725: * lots of internal clean-ups in character escapes
726: * un-break literal contexts in man(7) documents
727: * improve -Thtml output for -man
728: * add mandoc(1) -Tpdf support
729:
730: Changes in version 1.10.4, released on July 12, 2010
731:
732: * Lots of features developed during both "Summer of Code" and the
733: OpenBSD c2k10 hackathon:
734: * minimal "ds" roff(7) symbols are supported
735: * beautified SYNOPSIS section output
736: * acceptance of scope-block breakage in mdoc(7)
737: * clarify error message status
738: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 739: * see also changes in 1.10.3
740:
741: Changes in version 1.10.3, June 29, 2010, NOT released
742:
743: * variable font-width and paper-size support in mandoc(1) -Tps output
744: * "Bk" mdoc(7) support
1.1 schwarze 745:
746: Changes in version 1.10.2, released on June 19, 2010
747:
748: * Small release featuring text-decoration in -Tps output,
749: a few minor relaxations of errors, and some optimisations.
750:
751: Changes in version 1.10.1, released on June 7, 2010
752:
753: * This primarily focusses on the "Bl" and "It" macros described in
754: mdoc(7). Multi-line column support is now fully compatible with groff,
755: as are implicit list entries for columns.
756: * Removed manuals(7) in favour of http://manpages.bsd.lv.
757: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
758: in MANUAL STRUCTURE) has also been considerably simplified compared
759: to groff's method.
760: * Furthermore, the -Owidth=width output option has been added to -Tascii,
761: see mandoc(1).
762: * Lastly, initial PostScript output has been added with the -Tps option
763: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
764: font decorations.
765:
766: Changes in version 1.10.0, released on May 29, 2010
767:
768: * Release consisting of the results from the m2k10 hackathon and up-merge
769: from OpenBSD. This requires a significant note of thanks to Ingo
770: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
771: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
772: Ingo's m2k10 report) follow in no particular order:
773: * a libroff preprocessor in front of libmdoc and libman stripping out
774: roff(7) instructions;
775: * end-of-sentence (EOS) detection in free-form and macro lines;
776: * correct handling of tab-separated columnar lists in mdoc(7);
777: * improved main calling routines to optionally use mmap(3) for better
778: performance;
779: * cleaned up exiting when invoked as -Tlint or over multiple files
780: with -fign-errors;
781: * error and warning message handling re-written to be unified for
782: libroff, libmdoc, and libman;
783: * handling of badly-nested explicit-scoped macros;
784: * improved free-form text parsing in libman and libmdoc;
785: * significant GNU troff compatibility improvements in -Tascii,
786: largely in terms of spacing;
787: * a regression framework for making sure the many fragilities of GNU
788: troff aren't trampled in subsequent work;
789: * support for -Tascii breaking at hyphens encountered in free-form text;
790: * and many more minor fixes and improvements
791:
792: Changes in version 1.9.25, released on May 13, 2010
793:
794: * Fixed handling of "\*(Ba" escape.
795: * Backed out -fno-ign-chars (pointless complexity).
796: * Fixed erroneous breaking of literal lines.
797: * Fixed SYNOPSIS breaking lines before non-initial macros.
798: * Changed default section ordering.
799: * Most importantly, the framework for end-of-sentence double-spacing is
800: in place, now implemented for the "end-of-sentence, end-of-line" rule.
801: * This is a stable roll-back point before the mandoc hackathon in Rostock!
802:
803: Changes in version 1.9.24, released on May 9, 2010
804:
805: * Rolled back break-at-hyphen.
806: * -DUGLY is now the default (no feature splits!).
807: * Free-form text is not de-chunked any more: lines are passed
808: whole-sale into the front-end, including whitespace.
809: * Added mailing lists.
810:
811: Changes in version 1.9.23, released on April 7, 2010
812:
813: * mdocml has been linked to the OpenBSD build.
814: * This version incorporates many small changes, mostly from patches
815: by OpenBSD, allowing crufty manuals to slip by with warnings instead
816: of erroring-out.
817: * Some subtle semantic issues, such as punctuation scope, have also
818: been fixed.
819: * Lastly, some issues with -Thtml have been fixed, which prompted an
820: update to the online manual pages style layout.
821:
822: Changes in version 1.9.22, released on March 31, 2010
823:
824: * Adjusted merge of the significant work by Ingo Schwarze
825: in getting "Xo" blocks (block full implicit, e.g., "It"
826: for non-columnar lists) to work properly. This isn't
827: enabled by default: you must specify -DUGLY as a compiler
828: flag (see the Makefile for details).
829:
830: Changes in version 1.9.20, released on March 30, 2010
831:
832: * More efforts to get roff instructions in man(7) documents under
833: control. Note that roff instructions embedded in line-scoped,
834: next-line macros (e.g. "B") are not supported.
835: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
836: are now correctly handled.
837:
838: Changes in version 1.9.18, released on March 27, 2010
839:
840: * Many fixes (largely pertaining to scope)
841: and improvements (e.g., handling of apostrophe-control macros,
842: which fixes the strange "BR" seen in some macro output)
843: to handling roff instructions in man(7) documents.
844:
845: Changes in version 1.9.17, released on March 25, 2010
846:
847: * Accept perlpod(1) standard preamble.
848: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
849: roff macro blocks.
850:
851: Changes in version 1.9.16, released on March 22, 2010
852:
853: * Inspired by patches and bug reports by Ingo Schwarze,
854: allowed man(7) to accept non-printing elements to be nested
855: within next-line scopes, such as "br" within "B" or "TH",
856: which is valid roff.
857: * Longsoon architecture also noted and Makefile cleaned up.
858:
859: Changes in version 1.9.15, released on February 18, 2010
860:
861: * Moved to our new BSD.lv home.
862: * XHTML is now an acceptable output mode for mandoc(1);
863: * "Xr" made more compatible with groff;
864: * "Vt" fixed when invoked in SYNOPSIS;
865: * "\\" escape removed;
866: * end-of-line white-space detected for all lines;
867: * subtle bug fixed in list display for some modes;
868: * compatibility layer checked in for compilation in diverse
869: UNIX systems;
870: * and column lengths handled correctly.
