1$Id: NEWS,v 1.26 2017/07/28 14:57:56 schwarze Exp $ 2 3This file lists the most important changes in the mandoc.bsd.lv distribution. 4 5Changes in version 1.14.3, released on August 5, 2017 6 7 --- BUG FIXES --- 8 * man(7): Do not crash with out-of-bounds read access to a constant 9 array if .sp or a blank line immediately precedes .SS or .SH. 10 * mdoc(7): Do not crash with out-of-bounds read access to a constant 11 array if .sp or a blank line precede the first .Sh macro. 12 * tbl(7): Ignore explicitly specified negative column widths rather than 13 wrapping around to huge numbers and risking memory exhaustion. 14 * man(1): No longer use names that only occur in the SYNOPSIS section. 15 Gets rid of some surprising behaviour and bogus warnings. 16 --- THANKS TO --- 17 Leah Neukirchen (Void Linux), Markus Waldeck (Debian), 18 Peter Bui (nd.edu), and Yuri Pankov (illumos) for bug reports. 19 20Changes in version 1.14.2, released on July 28, 2017 21 22 --- MAJOR NEW FEATURES --- 23 * New mdoc(7) -Tmarkdown output mode. 24 * For -Thtml, implement internal hyperlinks pointing to authoritative 25 definitions of various syntax elements, similar to the ctags(1)-like 26 less(1) :t internal searching in terminal mode. 27 * Provide a superset of the functionality of the former mdoclint(1) 28 utility and a new -Wstyle message level with several new messages, 29 including validity checking of .Xr cross references. 30 * tbl(7): Implement automatic line breaking inside individual table 31 cells, and several other formatting improvements. 32 * eqn(7): Complete rewrite of the lexer, resulting in several bugfixes. 33 * Continue parser unification, in particular allowing generation 34 of syntax tree nodes on the roff(7) level, allowing implementation 35 of many additional roff requests. 36 --- REMOVED FUNCTIONALITY --- 37 * Delete the manpage(1) utility. It was never enabled in any release. 38 * Delete the -Txhtml command line option. It has been an obsolete 39 alias for the -Thtml output mode for more than two years. 40 --- MINOR NEW FEATURES --- 41 * -Tlint now puts parser messages on stdout instead of stderr, 42 making commands like "man -l -Tlint *.1" useful. 43 * mdoc(7): Various .Lk formatting improvements. 44 * mdoc(7) -Thtml: Better CSS for .Bl lists. 45 * man(7): Implement the .MT/.ME block macro (mailto hyperlink). 46 * man(7): Implement the .DT macro (restore default tab positions). 47 * man(7): Improved support for manuals generated with reStructuredText 48 by partial support for the \n[an-margin] number register. 49 * man(7) -Thtml: Support deep linking to .SH and .SS headers. 50 * tbl(7): Implement the "allbox" table option. 51 * tbl(7): Implement the column spacing and the 'w' (minimum column 52 width) layout modifiers. 53 * tbl(7): Significant improvements of the manual page. 54 * eqn(7): Much improved font selection, including recognition of 55 well-known function names, and a few other formatting improvements. 56 * eqn(7) -Thtml: Use <mn> and <mo> in addition to <mi>. 57 * roff(7): Implement the .ce (centering), .mc (margin character), 58 .rj (right justify), .ta (define tab stops), .ti (temporary indent), 59 .als (macro alias), .ec and .eo (escape character control), 60 .po (page offset), and .rn (macro rename) requests. 61 * roff(7) .am: Implement appending to mdoc(7) and man(7) macros. 62 * roff(7): implement the \h (horizontol motion), \l (horizontal 63 line drawing), and \p (break output line) escape sequences, 64 and also several additional character escape sequences. 65 * roff(7): Implement the 'd' conditional (macro or string defined). 66 * man.cgi(8) now uses pledge(2), too. 67 * regress.pl(1): simpler user interface, better summary output, 68 simpler code, and no more recursion. 69 --- THANKS TO --- 70 * Anthony Bentley (OpenBSD) for the implementation of .MT/.ME, 71 reports of many bugs and missing features, and suggestions 72 for a number of feature and documentation improvements. 73 * Sebastien Marie (OpenBSD) for two source code patches and 74 for some useful discussions. 75 * Florian Obser (OpenBSD) for a bugfix patch and a bug report. 76 * Jonathan Gray (OpenBSD) for several bug reports from afl(1) 77 and several more from static analysis tools. 78 * Theo Buehler (OpenBSD) for several bug reports, most from afl(1). 79 * Jason McIntyre (OpenBSD) for many useful discussions about a 80 wide variety of topics, lots of continuous testing, a number of 81 bug reports, and some suggestions for messages and documentation. 82 * Thomas Klausner (NetBSD) for lots of help while migrating 83 mdoclint(1) functionality to mandoc -Tlint, for suggesting 84 several useful new messages, and for release testing. 85 * Reyk Floeter (OpenBSD) and Vsevolod Stakhov (FreeBSD) for 86 suggesting a markdown output mode. 87 * Thomas Guettler for suggesting -Thtml internal hyperlinks. 88 * Yuri Pankov (Illumos) for inspiring new warning messages and 89 for extensive release testing. 90 * Anton Lindqvist and TJ Townsend (both OpenBSD) and Jan Stary 91 for multiple bug reports. 92 * Leah Neukirchen (Void Linux) for bug reports and release testing. 93 * Michael Stapelberg (Debian) for suggesting feature improvements 94 and for release testing. 95 * Martin Natano and Theo de Raadt (both OpenBSD), Andreas Voegele, 96 Gabriel Guzman, Gonzalo Tornaria, Markus Waldeck, and Raf Czlonka 97 for bug reports. 98 * Antoine Jacoutot (OpenBSD) and Steffen Nurpmeso for suggesting 99 feature improvements. 100 * Dag-Erling Smoergrav (FreeBSD) for inspiring new warning messages. 101 * Ted Unangst and Marc Espie (OpenBSD) for providing useful ideas. 102 * Svyatoslav Mishyn (Crux Linux) for release testing. 103 * Carsten Kunze (Heirloom roff) for help keeping mandoc and groff 104 compatible and for committing some of my patches to groff. 105 106Changes in version 1.14.1, released on February 21, 2017 107 108 --- MAJOR NEW FEATURES --- 109 * apropos(1): Reimplement complete semantic search functionality 110 without the dependency on SQLite3, using only POSIX APIs. 111 This comes with a completely new mandoc.db(5) file format. 112 * man(1): Support more than one tag entry for the same search term, 113 plus some minor improvements to the less(1) :t support. 114 * -Thtml: Use real macro names for CSS classes. 115 Systematic cleanup of and many improvements to mandoc.css. 116 * -Thtml: Produce human readable HTML code by using indentation 117 and better line breaks.

in nested blocks of mismatching type. 153 * man(1): Fix NULL dereference when the first of multiple pages 154 shown was preformatted. 155 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 156 caused by partial implicit macros inside .Bl -column table cells. 157 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 158 for macro sequences like .Bl .Bl .It Bo .El .It. 159 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 160 caused by .Ta following a nested .Bl -column breaking another block. 161 * mdoc(7): Fix syntax tree corruption sometimes leading to NULL 162 dereference caused by indirectly broken .Nd or .Nm blocks. 163 * mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns. 164 * mdoc(7): Fix NULL dereference in some specific cases of a 165 block-end macro calling another block-end macro. 166 * mdoc(7): Fix NULL dereference if the only child of the head 167 of the first .Sh was an empty in-line macro. 168 * eqn(7): Fix NULL dereference in the terminal formatter 169 for empty matrices and empty square roots. 170 * mdoc(7): Fix an assertion failure for a .Bd without a type that 171 breaks another block. 172 * mdoc(7): Fix an assertion failure that happened for some .Bl -column 173 lists containing a column width of "-4n", "-3n", or "-2n". 174 * mdoc(7): Fix an assertion failure caused by .Bl -column without .It 175 but containing eqn(7) or tbl(7) code. 176 * roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf. 177 * roff(7): Fix an assertion failures caused by whitespace inside \o'' 178 (overstrike) sequences. 179 * -Thtml: Fix an assertion failure caused by -Oman or -Oincludes of 180 excessive length. 181 --- PORTABILITY IMPROVEMENTS --- 182 * man(1): Do not mix stdio narrow and wide stream orientation 183 on stdout, which could cause output corruption on glibc. 184 * mandoc(1): Autodetect a suitable locale for -Tutf8 mode. 185 * ./configure: Autodetect whether PATH_MAX and O_DIRECTORY are defined. 186 * ./configure: Autodetect if nanosleep(3) needs -lrt. 187 * ./configure: Provide an ${LN} configuration variable. 188 * ./configure: Put compiler arguments that may contain -l at the end. 189 --- MINOR BUGFIXES --- 190 * mdoc(7): Fix SYNOPSIS output if the first child of .Nm is a macro. 191 * mdoc(7) -Thtml: Improve formatting of .Bl -tag with short tags. 192 * man(7) -Thtml: Preserve whitespace in .nf (nofill) mode. 193 * mandoc(1): Error out on invalid output options on the command line. 194 --- STRUCTURAL CHANGES, no functional change --- 195

designing the new mandocd(8) 199 and parts of the new catman(8), for release testing, and for a 200 number of patches and bug reports. 201 * Baptiste Daroussin (FreeBSD) for profiling the new makewhatis(8) 202 implementation and suggesting an algorithmic improvement which 203 more than doubled performance, and for a few bug reports. 204 * Ed Maste (FreeBSD) for an important patch improving reproducibility 205 of builds in makewhatis(8), and for a few bug reports. 206 * Theo Buehler (OpenBSD) for almost twenty important bug reports, 207 most of them found by systematic afl(1) fuzzing. 208 * Benny Lofgren, David Dahlberg, and in particular Vadim Zhukov 209 for crucial help in getting .Bl -tag CSS formatting fixed. 210 * Svyatoslav Mishyn (Crux Linux) for an initial version of the

\s10 to \s39 for \s(10 to \s(39. 452 * roff(7): Correctly escape quotes when expanding macro arguments. 453 * roff(7): Correctly handle scaling units in numerical expressions, 454 and some other improvements to the parsing of numerical expressions. 455 * roff(7): Three minor fixes with respect to evaluation of conditionals. 456 * roff(7): Let .it accept numerical expressions, not just constants. 457 * mandoc_char(7): Correct some character names and renderings. 458 * If earlier files set a non-zero exit status, never reset it to zero. 459 --- THANKS TO --- 460 * Jonathan Gray

and MathML output, and various other code contributions. 539 * Jonathan Gray (OpenBSD) for extensive testing with afl (the 540 American Fuzzy Lop security fuzzer) resulting in many bug reports. 541 * Anthony Bentley (OpenBSD), Baptiste Daroussin (FreeBSD), Daniel 542 Dickman, Doug Hogan, Jason McIntyre, Theo de Raadt (OpenBSD), 543 and Martin Natano for source code patches. 544 * Carsten Kunze (Heirloom troff), Daniel Levai (Slackware), 545 Garrett D'Amore (illumos), Giovanni Becchis, Matthew Dempsky, 546 Stuart Henderson, Ted Unangst, Todd Miller (OpenBSD), Thomas 547 Klausner (NetBSD), Ulrich Spoerlein (FreeBSD), Justin Haynes, 548 Marcus Merighi, Sebastien Marie, Steffen Nurpmeso and Theo Buehler 549 for bug reports. 550 551Changes in version 1.13.1, released on August 10, 2014 552 553 --- MAJOR NEW FEATURES --- 554 * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite 555 based on SQLite3 is now included. 556 * The roff(7) parser now provides an almost complete implementation 557 of numerical expressions. 558 * Warning and error messages have been improved in many ways. 559 Almost all fatal errors were downgraded to normal errors and some 560 even to warnings. Almost all messages now mention the macro where 561 the issue is detected and many indicate the workaround employed. 562 The mandoc(1) manual now includes a list explaining all messages. 563 --- MINOR NEW FEATURES --- 564 * The roff(7) parser now supports the .ami (append to macro with 565 indirectly specified name), .as (append to user-defined 566 string), .dei (define macro with indirectly specified name), 567 .ll (line length), and .rr (remove register) requests. 568 * The roff(7) parser now supports string comparison and numerical 569 conditionals in the .if and .ie requests. 570 * The roff parser now fully supports the \B (validate numerical 571 expression) and partially supports the \w (measure text width) 572 escape sequences. 573 * The terminal formatter now supports the \: (optional line break) 574 escape sequence. 575 * The roff parser now supports expansion of user-defined strings 576 involving indirect references. 577 * The roff(7) parser now handles some pre-defined read-only 578 number registers that occur in the pod2man(1) preamble. 579 * For backward compatibility, the mdoc(7) parser and formatters 580 now support the obsolete macros .En, .Es, .Fr, and .Ot. 581 * The mdoc(7) formatter non partially supports .Bd -centered. 582 * tbl(7) now handles leading and trailing vertical lines. 583 * The build system now provides fallback versions of strcasestr(3) 584 and strsep(3) for systems lacking them. 585 * The mdoc(7) manual now explains how various standards 586 supported by the .St macro are related to each other. 587 --- BUGFIXES --- 588 * In the roff(7) parser, several bugs were fixed with respect 589 to closing conditional blocks on macro lines. 590 * Parsing of roff(7) identifiers and escape sequences was improved 591 in multiple respects. 592 * In the mdoc(7) parser, the handling of defective document 593 prologues was improved in multiple ways. 594 * The mdoc(7) parser no longer skips content before the first section 595 header, and it no longer deletes non-.% content from .Rs blocks. 596 * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers. 597 * In the mdoc(7) parser, handling of .Sm with missing or invalid 598 arguments was corrected. 599 * In the mdoc(7) parser, trailing punctuation at the end of partial 600 implicit macros no longer triggers end-of-sentence spacing. 601 * In the terminal formatter, two crashes were fixed: one triggered by 602 excessive indentation and another by excessively long .Nm arguments. 603 * In the terminal formatter, a floating point rounding bug was 604 fixed that sometimes caused an off-by-one error in indentation. 605 * In the UTF-8 formatter, rendering of accents, breakable hyphens, 606 and non-breakable spaces was corrected. 607 * In the HTML formatter, encoding of special characters was 608 corrected in multiple respects. 609 * In the mdoc(7) formatter, rendering of .Ex and .Rv was 610 improved for various edge cases. 611 * In the mdoc(7) formatter, handling of empty .Bl -inset item 612 heads was improved. 613 * In the man(7) formatter, some bugs were fixed with respect 614 to same-line detection in the context of .TP and .nf macros, 615 and the indentation of .IP and .TP blocks was improved. 616 * The mandoc(3) library no longer prints to stderr. 617 --- THANKS TO --- 618 Abhinav Upadhyay (NetBSD), Andreas Voegele, Anthony Bentley (OpenBSD), 619 Christian Weisgerber (OpenBSD), Havard Eidnes (NetBSD), Jan Stary, 620 Jason McIntyre (OpenBSD), Jeremie Courreges-Anglas (OpenBSD), 621 Joerg Sonnenberger (NetBSD), Juan Francisco Cantero Hurtado (OpenBSD), 622 Marc Espie (OpenBSD), Matthias Scheler (NetBSD), Pascal Stumpf (OpenBSD), 623 Paul Onyschuk (Alpine Linux), Sebastien Marie, Steffen Nurpmeso, 624 Stuart Henderson (OpenBSD), Ted Unangst (OpenBSD), Theo de Raadt (OpenBSD), 625 Thomas Klausner (NetBSD), and Ulrich Spoerlein (FreeBSD) 626 for reporting bugs and missing features. 627 628Changes in version 1.12.3, released on December 31, 2013 629 630 * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation 631 now work correctly for .Fo/.Fa/.Fc and .Fn blocks. 632 Thanks to Franco Fichtner for doing part of the work. 633 * The mdoc(7) .Bk macro got some addititonal bugfixes. 634 * In mdoc(7) macro arguments, double quotes can now be quoted 635 by doubling them, just like in man(7). 636 Thanks to Tsugutomo ENAMI for the patch. 637 * At the end of man(7) macro lines, end-of-sentence spacing 638 now works. Thanks to Franco Fichtner for the patch. 639 * For backward compatibility, the man(7) parser now supports the 640 man-ext .UR/.UE (uniform resource identifier) block macros. 641 * The man(7) parser now handles closing blocks that are not open 642 more gracefully. 643 * The man(7) parser now ignores blank lines right after .SH and .SS. 644 * In the man(7) formatter, reset indentation when leaving a block, 645 not just when entering the next one. 646 * The roff(7) .nr request now supports incrementing and decrementing 647 number registers and stops parsing the number right before the 648 first non-digit character. 649 * The roff(7) parser now supports the alternative escape sequence 650 syntax \C'uXXXX' for Unicode characters. 651 * The roff(7) parser now parses and ignores the .fam (font family) 652 and .hw (hyphenation points) requests and the \d and \u escape 653 sequences. 654 * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE. 655 656Changes in version 1.12.2, released on Oktober 5, 2013 657 658 * The mdoc(7) to man(7) converter, to be called as mandoc -Tman, 659 is now fully functional. 660 * The mandoc(1) utility now supports the -Ios (default operating system) 661 input option, and the -Tutf8 output mode now actually works. 662 * The mandocdb(8) utility no longer truncates existing databases when 663 starting to build new ones, but only replaces them when the build 664 actually succeeds. 665 * The man(7) parser now supports the PD macro (paragraph distance), 666 and (for GNU man-ext compatibility only) EX (example block) and EE 667 (example end). Plus several bugfixes regarding indentation, line 668 breaks, and vertical spacing, and regarding RS following TP. 669 * The roff(7) parser now supports the \f(BI (bold+italic) font escape, 670 the \z (zero cursor advance) escape and the cc (change control 671 character) and it (input line trap) requests. Plus bugfixes regarding 672 the \t (tab) escape, nested escape sequences, and conditional requests. 673 * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting 674 enclosures, delimiter handling, list indentation and horizontal and 675 vertical spacing, formatting of the Lk, %U, and %C macros, plus some 676 bugfixes related to the handling of syntax errors like badly nested 677 font blocks, stray Ta macros outside column lists, unterminated It Xo 678 blocks, and non-text children of Nm blocks. 679 * In tbl(7), the width of horizontal spans and the vertical spacing 680 around tables was corrected, and in man(7) files, a crash was fixed 681 that was triggered by some particular unclosed T{ macros. 682 * For mandoc developers, we now provide a tbl(3) library manual and 683 gmdiff, a very small, very simplistic groff-versus-mandoc output 684 comparison tool. 685 * Provide this NEWS file. 686 687Changes in version 1.12.1, released on March 23, 2012 688 689 * Significant work on apropos(1) and mandocdb(8). These tools are now 690 much more robust. A whatis(1) implementation is now handled as an 691 apropos(1) mode. These tools are also able to minimally handle 692 pre-formatted pages, that is, those already formatted by another 693 utility such as GNU troff. 694 * The man.cgi(7) script is also now available for wider testing. 695 It interfaces with mandocdb(8) manuals cached by catman(8). 696 HTML output is generated on-the-fly by libmandoc or internal 697 methods to convert pre-formatted pages. 698 * The mailing list archive for the discuss and tech lists are being 699 hosted by Gmane at gmane.comp.tools.mdocml.user and 700 gmane.comp.tools.mdocml.devel, respectively. 701 702Changes in version 1.12.0, released on October 8, 2011 703 704 * This version features a new, work-in-progress mandoc(1) output mode: 705 -Tman. This mode allows a system maintainer to distribute man(7) 706 media for older systems that may not natively support mdoc(7), such 707 as old Solaris systems. 708 * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes. 709 * While adding features, an apropos(1) utility has been merged from the 710 mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic 711 search of manual content. apropos(1) is different from the traditional 712 apropos primarily in allowing keyword search (such as for functions, 713 utilities, etc.) and regular expressions. Note that the calling 714 syntax for apropos is likely to change as it settles down. 715 * In documentation news, the mdoc(7) and man(7) manuals have been 716 made considerably more readable by adding MACRO OVERVIEW sections, by 717 moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual, 718 and by moving the very technical MACRO SYNTAX sections down to the 719 bottom of the page. 720 * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables 721 was rewritten completely. It is now compatible with groff(1), both 722 with and without frames and rulers. 723 * Nesting of indented blocks is now supported in man(7), and several 724 bugs were fixed regarding indentation and alignment. 725 * The page headers in mdoc(7) are now nicer for very long titles. 726 727Changes in version 1.11.7, released on September 2, 2011 728 729 * Added demandoc(1) utility for stripping away macros and escapes. 730 This replaces the historical deroff(1) utility. 731 * Also improved the mdoc(7) and man(7) manuals. 732 733Changes in version 1.11.6, released on August 16, 2011 734 735 * Handling of tr macro in roff(7) implemented. This makes Perl 736 documentation much more readable. Hyphenation is also now enabled in 737 man(7) format documents. Many other general improvements have been 738 implemented. 739 740Changes in version 1.11.5, released on July 24, 2011 741 742 * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn 743 input (although few GNU extensions are accepted, nor is mixing 744 low-level roff with eqn). See the eqn(7) manual for details. 745 For the time being, equations are rendered as simple in-line text. 746 The equation parser satisfies the language specified in the 747 Second Edition User's Guide: 748 http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps 749 750Changes in version 1.11.4, released on July 12, 2011 751 752 * Bug-fixes and clean-ups across all systems, especially in mandocdb(8) 753 and the man(7) parser. This release was significantly assisted by 754 participants in OpenBSD's c2k11. Thanks! 755 756Changes in version 1.11.3, released on May 26, 2011 757 758 * Introduce locale-encoding of output with the -Tlocale output option and 759 Unicode escaped-character input. See mandoc(1) and mandoc_char(7), 760 respectively, for details. This allows for non-ASCII characters (e.g., 761 \[u5000]) to be rendered in the locale's encoding, if said environment 762 supports wide-character encoding (if it does not, -Tascii is used 763 instead). Locale support can be turned off at compile time by removing 764 -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym 765 for -Tascii. 766 * Furthermore, multibyte-encoded documents, such as those in UTF-8, may 767 be on-the-fly recoded into mandoc(1) input by using the newly-added 768 preconv(1) utility. Note: in the future, this feature may be 769 integrated into mandoc(1). 770 771Changes in version 1.11.2, released on May 12, 2011 772 773 * Corrected some installation issues in version 1.11.1. 774 * Further migration to libmandoc. 775 * Initial public release (this utility is very much under development) 776 of mandocdb(8). This utility produces keyword databases of manual 777 content, which features semantic querying of manual content. 778 779Changes in version 1.11.1, released on April 4, 2011 780 781 * The earlier libroff, libmdoc, and libman soup have been merged into 782 a single library, libmandoc, which manages all aspects of parsing 783 real manuals, from line-handling to tbl(7) parsing. 784 * As usual, many general fixes and improvements have also occurred. 785 In particular, a great deal of redundancy and superfluous code has 786 been removed with the merging of the backend libraries. 787 * see also the changes in 1.10.10 788 789Changes in version 1.10.10, March 20, 2011, NOT released 790 791 * Initial eqn(7) functionality is in place. For the time being, 792 this is limited to the recognition of equation blocks; 793 future version of mdocml will expand upon this framework. 794 795Changes in version 1.10.9, released on January 7, 2011 796 797 * Many back-end fixes have been implemented: argument handling (quoting), 798 man(7) improvements, error/warning classes, and many more. 799 * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in 800 the roff(7) manual) has been merged from tbl.bsd.lv. Output is still 801 minimal, especially for -Thtml and -Txhtml, but manages to at least 802 display data. This means that mandoc(1) now has built-in support 803 for two troff preprocessors via libroff: soelim(1) and tbl(1). 804 805Changes in version 1.10.8, released on December 24, 2010 806 807 * Overhauled the -Thtml and -Txhtml output modes. They now display 808 readable output in arbitrary browsers, including text-based ones like 809 lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section 810 for examples. Attention: available style-sheet classes have been 811 considerably changed! See the example.style.css file for details. 812 Lastly, libmdoc and libman have been cleaned up and reduced in size 813 and complexity. 814 * see also the changes in 1.10.7 815 816Changes in version 1.10.7, December 6, 2010, NOT released 817 818 Significant improvements merged from OpenBSD downstream, including: 819 * many new roff(7) components, 820 * in-line implementation of troff's soelim(1), 821 * broken-block handling, 822 * overhauled error classifications, and 823 * cleaned up handling of error conditions. 824 825Changes in version 1.10.6, released on September 27, 2010 826 827 * Calling conventions for mandoc(1) have changed: -W improved and -f 828 deprecated. 829 * Non-ASCII characters are also now uniformly discarded. 830 * Lots of documentation improvements. 831 * Many incremental fixes accomodating for groff's more interesting 832 productions. 833 * Lastly, pod2man(1) preambles are now fully accepted after some 834 considerable roff(7) and special character support. 835 836Changes in version 1.10.5, released on July 27, 2010 837 838 * Primarily a bug-fix and polish release, but including -Tpdf support 839 in mandoc(1) by way of "Summer of Code". Highlights: 840 * fix "Sm" and "Bd" handling 841 * fix end-of-sentence handling for embedded sentences 842 * polish man(7) documentation 843 * document all mdoc(7) macros 844 * polish mandoc(1) -Tps output 845 * lots of internal clean-ups in character escapes 846 * un-break literal contexts in man(7) documents 847 * improve -Thtml output for -man 848 * add mandoc(1) -Tpdf support 849 850Changes in version 1.10.4, released on July 12, 2010 851 852 * Lots of features developed during both "Summer of Code" and the 853 OpenBSD c2k10 hackathon: 854 * minimal "ds" roff(7) symbols are supported 855 * beautified SYNOPSIS section output 856 * acceptance of scope-block breakage in mdoc(7) 857 * clarify error message status 858 * many minor bug-fixes and formatting issues resolved 859 * see also changes in 1.10.3 860 861Changes in version 1.10.3, June 29, 2010, NOT released 862 863 * variable font-width and paper-size support in mandoc(1) -Tps output 864 * "Bk" mdoc(7) support 865 866Changes in version 1.10.2, released on June 19, 2010 867 868 * Small release featuring text-decoration in -Tps output, 869 a few minor relaxations of errors, and some optimisations. 870 871Changes in version 1.10.1, released on June 7, 2010 872 873 * This primarily focusses on the "Bl" and "It" macros described in 874 mdoc(7). Multi-line column support is now fully compatible with groff, 875 as are implicit list entries for columns. 876 * Removed manuals(7) in favour of http://manpages.bsd.lv. 877 * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation 878 in MANUAL STRUCTURE) has also been considerably simplified compared 879 to groff's method. 880 * Furthermore, the -Owidth=width output option has been added to -Tascii, 881 see mandoc(1). 882 * Lastly, initial PostScript output has been added with the -Tps option 883 to mandoc(1). It's brutally simple at the moment: fixed-font, with no 884 font decorations. 885 886Changes in version 1.10.0, released on May 29, 2010 887 888 * Release consisting of the results from the m2k10 hackathon and up-merge 889 from OpenBSD. This requires a significant note of thanks to Ingo 890 Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work, 891 and again to Joerg for hosting m2k10. Highlights (mostly cribbed from 892 Ingo's m2k10 report) follow in no particular order: 893 * a libroff preprocessor in front of libmdoc and libman stripping out 894 roff(7) instructions; 895 * end-of-sentence (EOS) detection in free-form and macro lines; 896 * correct handling of tab-separated columnar lists in mdoc(7); 897 * improved main calling routines to optionally use mmap(3) for better 898 performance; 899 * cleaned up exiting when invoked as -Tlint or over multiple files 900 with -fign-errors; 901 * error and warning message handling re-written to be unified for 902 libroff, libmdoc, and libman; 903 * handling of badly-nested explicit-scoped macros; 904 * improved free-form text parsing in libman and libmdoc; 905 * significant GNU troff compatibility improvements in -Tascii, 906 largely in terms of spacing; 907 * a regression framework for making sure the many fragilities of GNU 908 troff aren't trampled in subsequent work; 909 * support for -Tascii breaking at hyphens encountered in free-form text; 910 * and many more minor fixes and improvements 911 912Changes in version 1.9.25, released on May 13, 2010 913 914 * Fixed handling of "\*(Ba" escape. 915 * Backed out -fno-ign-chars (pointless complexity). 916 * Fixed erroneous breaking of literal lines. 917 * Fixed SYNOPSIS breaking lines before non-initial macros. 918 * Changed default section ordering. 919 * Most importantly, the framework for end-of-sentence double-spacing is 920 in place, now implemented for the "end-of-sentence, end-of-line" rule. 921 * This is a stable roll-back point before the mandoc hackathon in Rostock! 922 923Changes in version 1.9.24, released on May 9, 2010 924 925 * Rolled back break-at-hyphen. 926 * -DUGLY is now the default (no feature splits!). 927 * Free-form text is not de-chunked any more: lines are passed 928 whole-sale into the front-end, including whitespace. 929 * Added mailing lists. 930 931Changes in version 1.9.23, released on April 7, 2010 932 933 * mdocml has been linked to the OpenBSD build. 934 * This version incorporates many small changes, mostly from patches 935 by OpenBSD, allowing crufty manuals to slip by with warnings instead 936 of erroring-out. 937 * Some subtle semantic issues, such as punctuation scope, have also 938 been fixed. 939 * Lastly, some issues with -Thtml have been fixed, which prompted an 940 update to the online manual pages style layout. 941 942Changes in version 1.9.22, released on March 31, 2010 943 944 * Adjusted merge of the significant work by Ingo Schwarze 945 in getting "Xo" blocks (block full implicit, e.g., "It" 946 for non-columnar lists) to work properly. This isn't 947 enabled by default: you must specify -DUGLY as a compiler 948 flag (see the Makefile for details). 949 950Changes in version 1.9.20, released on March 30, 2010 951 952 * More efforts to get roff instructions in man(7) documents under 953 control. Note that roff instructions embedded in line-scoped, 954 next-line macros (e.g. "B") are not supported. 955 * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a", 956 are now correctly handled. 957 958Changes in version 1.9.18, released on March 27, 2010 959 960 * Many fixes (largely pertaining to scope) 961 and improvements (e.g., handling of apostrophe-control macros, 962 which fixes the strange "BR" seen in some macro output) 963 to handling roff instructions in man(7) documents. 964 965Changes in version 1.9.17, released on March 25, 2010 966 967 * Accept perlpod(1) standard preamble. 968 * Also accept (and discard) "de", "dei", "am", "ami", and "ig" 969 roff macro blocks. 970 971Changes in version 1.9.16, released on March 22, 2010 972 973 * Inspired by patches and bug reports by Ingo Schwarze, 974 allowed man(7) to accept non-printing elements to be nested 975 within next-line scopes, such as "br" within "B" or "TH", 976 which is valid roff. 977 * Longsoon architecture also noted and Makefile cleaned up. 978 979Changes in version 1.9.15, released on February 18, 2010 980 981 * Moved to our new BSD.lv home. 982 * XHTML is now an acceptable output mode for mandoc(1); 983 * "Xr" made more compatible with groff; 984 * "Vt" fixed when invoked in SYNOPSIS; 985 * "\\" escape removed; 986 * end-of-line white-space detected for all lines; 987 * subtle bug fixed in list display for some modes; 988 * compatibility layer checked in for compilation in diverse 989 UNIX systems; 990 * and column lengths handled correctly. 991 992For older releases, see the ChangeLog files 993in http://mandoc.bsd.lv/snapshots/ . 994
