1$Id: NEWS,v 1.32 2018/08/08 14:47:38 schwarze Exp $ 2 3This file lists the most important changes in the mandoc.bsd.lv distribution. 4 5Changes in version 1.14.4, released on August 8, 2018 6 7 --- MAJOR NEW FEATURES --- 8 * In ASCII output, render mathematical symbols and greek letters 9 as transliterations conveying the characters' meanings rather 10 than trying to imitate their shape. Consequently, such characters 11 can now be used in portable manual pages. All the same, please 12 limit their use to contexts where they really matter, for example 13 when showing complicated mathematical formulae. 14 * First steps towards better support for small screens in HTML 15 output (responsive design): avoid most style= attributes, in 16 particular all hard-coded indentations and column widths, and 17 provide a better mandoc.css style sheet with a @media query, 18 using em units throughout, and avoiding redundancy in selectors. 19 * Better HTML output with some more fitting HTML elements, eliminating 20 needless class= attributes, and avoiding various HTML syntax errors 21 (element nesting, URL-fragment syntax, duplicate id= attributes). 22 --- MINOR NEW FEATURES --- 23 * When a man(1) argument contains a slash, imply -l like in man-db. 24 * Use TIOCGWINSZ to reduce the default -Owidth and -Oindent during 25 interactive use on terminals narrower than 79 columns. 26 * Generated PostScript files are now more than 50% smaller. 27 * Terminal rendering of eqn(7) is improved in several respects. 28 * Simplified and nicer output from the mdoc(7) .Lk macro, formatting 29 all links in-line, even long ones. 30 * roff(7) \n+ and \n- numerical register auto-increment and -decrement 31 * roff(7) .nr optional third argument (auto-increment step size) 32 * Autodetect in ./configure whether the compiler can use -W and -static, 33 allowing to build on Solaris 10 and 11 without any configure.local. 34 --- RELIABILITY BUGFIXES --- 35 * Only activate UTF-8 output when the user really selected UTF-8, 36 not some other multibyte character encoding. 37 * Prevent excessive .ll arguments from generating infinite output. 38 * Fix out of bounds accesses to parse buffers that could happen when 39 using renamed or user defined macros after roff(7) conditionals. 40 * Avoid an assertion failure in certain .Bl -column lists. 41 * Avoid a NULL pointer access on deroff() failure after '.SS ""'. 42 * Fix a segfault that could be triggered by two invalid .Dt macros. 43 * Fix two syntax errors in generated PDF files. 44 * Properly state the page size in generated PostScript files. 45 * Close a memory leak caused by missing gzclose(3). 46 * Fix misformatting of man(7) documents lacking .SH macros 47 in PostScript and PDF output. 48 * And many minor bugfixes. 49 --- THANKS TO --- 50 * Marc Espie (OpenBSD) for implementing the size reduction of 51 PostScript files, one additional patch for code simplification, 52 and two bug reports. 53 * Theo Buehler (OpenBSD) for a bugfix patch, 54 and Theo de Raadt (OpenBSD) for checking it. 55 * John Gardner for more than a dozen suggestions regarding HTML output. 56 * Mike Williams for teaching me how to use %%DocumentMedia and 57 setpagedevice in PostScript files. 58 * Werner Lemberg (groff) for feedback on mdoc(7) language changes. 59 * Colin Watson (man-db) for feedback on man-db semantics. 60 * Jason McIntyre (OpenBSD) for lots of feedback and suggestions 61 on diagnostic messages and on the documentation. 62 * Thomas Klausner (NetBSD) for suggesting two new style messages 63 and one new feature, for two bug reports, and for release testing. 64 * Leah Neukirchen (Void Linux) for suggesting a new style message, 65 five bug reports, and release testing. 66 * Anthony Bentley (OpenBSD) for reporting multiple bugs and missing 67 features. 68 * Paul Irofti (OpenBSD) and Nate Bargmann for suggesting new features. 69 * Michael Stapelberg (Debian) for bug reports and release testing. 70 * Christian Weisgerber, Jonathan Gray, Stuart Henderson, 71 Ted Unangst (OpenBSD), Takeshi Nakayama (NetBSD), 72 Anton Lazarov, Jakub Klinkovsky, Jan Stary, Jesper Wallin, 73 Will Backmam, and Wolfgang Mueller for bug reports. 74 * Sevan Janiyan (NetBSD) for additions to lib.in. 75 * George Brown for suggesting code simplifications. 76 * David Coppa, Igor Sobrado (OpenBSD), and Alexander Kuleshov 77 for documentation improvements. 78 * Laura Morales and Raf Czlonka for questions resulting in better 79 documentation. 80 * Yuri Pankov (illumos) for release testing. 81 82Changes in version 1.14.3, released on August 5, 2017 83 84 --- BUG FIXES --- 85 * man(7): Do not crash with out-of-bounds read access to a constant 86 array if .sp or a blank line immediately precedes .SS or .SH. 87 * mdoc(7): Do not crash with out-of-bounds read access to a constant 88 array if .sp or a blank line precede the first .Sh macro. 89 * tbl(7): Ignore explicitly specified negative column widths rather than 90 wrapping around to huge numbers and risking memory exhaustion. 91 * man(1): No longer use names that only occur in the SYNOPSIS section. 92 Gets rid of some surprising behaviour and bogus warnings. 93 --- THANKS TO --- 94 Leah Neukirchen (Void Linux), Markus Waldeck (Debian), 95 Peter Bui (nd.edu), and Yuri Pankov (illumos) for bug reports. 96 97Changes in version 1.14.2, released on July 28, 2017 98 99 --- MAJOR NEW FEATURES --- 100 * New mdoc(7) -Tmarkdown output mode. 101 * For -Thtml, implement internal hyperlinks pointing to authoritative 102 definitions of various syntax elements, similar to the ctags(1)-like 103 less(1) :t internal searching in terminal mode. 104 * Provide a superset of the functionality of the former mdoclint(1) 105 utility and a new -Wstyle message level with several new messages, 106 including validity checking of .Xr cross references. 107 * tbl(7): Implement automatic line breaking inside individual table 108 cells, and several other formatting improvements. 109 * eqn(7): Complete rewrite of the lexer, resulting in several bugfixes. 110 * Continue parser unification, in particular allowing generation 111 of syntax tree nodes on the roff(7) level, allowing implementation 112 of many additional roff requests. 113 --- REMOVED FUNCTIONALITY --- 114 * Delete the manpage(1) utility. It was never enabled in any release. 115 * Delete the -Txhtml command line option. It has been an obsolete 116 alias for the -Thtml output mode for more than two years. 117 --- MINOR NEW FEATURES --- 118 * -Tlint now puts parser messages on stdout instead of stderr, 119 making commands like "man -l -Tlint *.1" useful. 120 * mdoc(7): Various .Lk formatting improvements. 121 * mdoc(7) -Thtml: Better CSS for .Bl lists. 122 * man(7): Implement the .MT/.ME block macro (mailto hyperlink). 123 * man(7): Implement the .DT macro (restore default tab positions). 124 * man(7): Improved support for manuals generated with reStructuredText 125 by partial support for the \n[an-margin] number register. 126 * man(7) -Thtml: Support deep linking to .SH and .SS headers. 127 * tbl(7): Implement the "allbox" table option. 128 * tbl(7): Implement the column spacing and the 'w' (minimum column 129 width) layout modifiers. 130 * tbl(7): Significant improvements of the manual page. 131 * eqn(7): Much improved font selection, including recognition of 132 well-known function names, and a few other formatting improvements. 133 * eqn(7) -Thtml: Use <mn> and <mo> in addition to <mi>. 134 * roff(7): Implement the .ce (centering), .mc (margin character), 135 .rj (right justify), .ta (define tab stops), .ti (temporary indent), 136 .als (macro alias), .ec and .eo (escape character control), 137 .po (page offset), and .rn (macro rename) requests. 138 * roff(7) .am: Implement appending to mdoc(7) and man(7) macros. 139 * roff(7): implement the \h (horizontol motion), \l (horizontal 140 line drawing), and \p (break output line) escape sequences, 141 and also several additional character escape sequences. 142 * roff(7): Implement the 'd' conditional (macro or string defined). 143 * man.cgi(8) now uses pledge(2), too. 144 * regress.pl(1): simpler user interface, better summary output, 145 simpler code, and no more recursion. 146 --- THANKS TO --- 147 * Anthony Bentley (OpenBSD) for the implementation of .MT/.ME, 148 reports of many bugs and missing features, and suggestions 149 for a number of feature and documentation improvements. 150 * Sebastien Marie (OpenBSD) for two source code patches and 151 for some useful discussions. 152 * Florian Obser (OpenBSD) for a bugfix patch and a bug report. 153 * Jonathan Gray (OpenBSD) for several bug reports from afl(1) 154 and several more from static analysis tools. 155 * Theo Buehler (OpenBSD) for several bug reports, most from afl(1). 156 * Jason McIntyre (OpenBSD) for many useful discussions about a 157 wide variety of topics, lots of continuous testing, a number of 158 bug reports, and some suggestions for messages and documentation. 159 * Thomas Klausner (NetBSD) for lots of help while migrating 160 mdoclint(1) functionality to mandoc -Tlint, for suggesting 161 several useful new messages, and for release testing. 162 * Reyk Floeter (OpenBSD) and Vsevolod Stakhov (FreeBSD) for 163 suggesting a markdown output mode. 164 * Thomas Guettler for suggesting -Thtml internal hyperlinks. 165 * Yuri Pankov (Illumos) for inspiring new warning messages and 166 for extensive release testing. 167 * Anton Lindqvist and TJ Townsend (both OpenBSD) and Jan Stary 168 for multiple bug reports. 169 * Leah Neukirchen (Void Linux) for bug reports and release testing. 170 * Michael Stapelberg (Debian) for suggesting feature improvements 171 and for release testing. 172 * Martin Natano and Theo de Raadt (both OpenBSD), Andreas Voegele, 173 Gabriel Guzman, Gonzalo Tornaria, Markus Waldeck, and Raf Czlonka 174 for bug reports. 175 * Antoine Jacoutot (OpenBSD) and Steffen Nurpmeso for suggesting 176 feature improvements. 177 * Dag-Erling Smoergrav (FreeBSD) for inspiring new warning messages. 178 * Ted Unangst and Marc Espie (OpenBSD) for providing useful ideas. 179 * Svyatoslav Mishyn (Crux Linux) for release testing. 180 * Carsten Kunze (Heirloom roff) for help keeping mandoc and groff 181 compatible and for committing some of my patches to groff. 182 183Changes in version 1.14.1, released on February 21, 2017 184 185 --- MAJOR NEW FEATURES --- 186 * apropos(1): Reimplement complete semantic search functionality 187 without the dependency on SQLite3, using only POSIX APIs. 188 This comes with a completely new mandoc.db(5) file format. 189 * man(1): Support more than one tag entry for the same search term, 190 plus some minor improvements to the less(1) :t support. 191 * -Thtml: Use real macro names for CSS classes. 192 Systematic cleanup of and many improvements to mandoc.css. 193 * -Thtml: Produce human readable HTML code by using indentation 194 and better line breaks.

bounds read access for .Bl -column starting 227 with a tab character instead of a child .It macro. 228 * mdoc(7): Fix syntax tree corruption leading to segfaults caused 229 by stray block end macros in nested blocks of mismatching type. 230 * man(1): Fix NULL dereference when the first of multiple pages 231 shown was preformatted. 232 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 233 caused by partial implicit macros inside .Bl -column table cells. 234 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 235 for macro sequences like .Bl .Bl .It Bo .El .It. 236 * mdoc(7): Fix syntax tree corruption leading to NULL dereference 237 caused by .Ta following a nested .Bl -column breaking another block. 238 * mdoc(7): Fix syntax tree corruption sometimes leading to NULL 239 dereference caused by indirectly broken .Nd or .Nm blocks. 240 * mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns. 241 * mdoc(7): Fix NULL dereference in some specific cases of a 242 block-end macro calling another block-end macro. 243 * mdoc(7): Fix NULL dereference if the only child of the head 244 of the first .Sh was an empty in-line macro. 245 * eqn(7): Fix NULL dereference in the terminal formatter 246 for empty matrices and empty square roots. 247 * mdoc(7): Fix an assertion failure for a .Bd without a type that 248 breaks another block. 249 * mdoc(7): Fix an assertion failure that happened for some .Bl -column 250 lists containing a column width of "-4n", "-3n", or "-2n". 251 * mdoc(7): Fix an assertion failure caused by .Bl -column without .It 252 but containing eqn(7) or tbl(7) code. 253 * roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf. 254 * roff(7): Fix an assertion failures caused by whitespace inside \o'' 255 (overstrike) sequences. 256 * -Thtml: Fix an assertion failure caused by -Oman or -Oincludes of 257 excessive length. 258 --- PORTABILITY IMPROVEMENTS --- 259 * man(1): Do not mix stdio narrow and wide stream orientation 260 on stdout, which could cause output corruption on glibc. 261 * mandoc(1): Autodetect a suitable locale for -Tutf8 mode. 262 * ./configure: Autodetect whether PATH_MAX and O_DIRECTORY are defined. 263 * ./configure: Autodetect if nanosleep(3) needs -lrt. 264 * ./configure: Provide an ${LN} configuration variable. 265 * ./configure: Put compiler arguments that may contain -l at the end. 266 --- MINOR BUGFIXES --- 267 * mdoc(7): Fix SYNOPSIS output if the first child of .Nm is a macro. 268 * mdoc(7) -Thtml: Improve formatting of .Bl -tag with short tags. 269 * man(7) -Thtml: Preserve whitespace in .nf (nofill) mode. 270 * mandoc(1): Error out on invalid output options on the command line. 271 --- STRUCTURAL CHANGES, no functional change --- 272

designing the new mandocd(8) 276 and parts of the new catman(8), for release testing, and for a 277 number of patches and bug reports. 278 * Baptiste Daroussin (FreeBSD) for profiling the new makewhatis(8) 279 implementation and suggesting an algorithmic improvement which 280 more than doubled performance, and for a few bug reports. 281 * Ed Maste (FreeBSD) for an important patch improving reproducibility 282 of builds in makewhatis(8), and for a few bug reports. 283 * Theo Buehler (OpenBSD) for almost twenty important bug reports, 284 most of them found by systematic afl(1) fuzzing.

manual is missing from an outdated database, let man(1) 448 show it anyway, using a KISS file system lookup as a fallback. 449 * Use this to always provide man(1), even without database support. 450 * Fatal errors no longer exist. If a file can be opened, mandoc 451 will produce some output; at worst, the output may be almost empty. 452 * New -Wunsupp message level. 453 --- POTENTIONALLY SECURITY RELEVANT BUGFIXES --- 454 * Fix a potential write buffer overrun on incomplete string conditionals. 455 http://mandoc.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.241 456 * Fix a potential write buffer overrun on backslash at EOF in a conditional. 457 http://mandoc.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.247 458 * Fix a use after free sometimes hit when validation deletes a block. 459 http://mandoc.bsd.lv/cgi-bin/cvsweb/mdoc_macro.c#rev1.180 460 --- MAJOR FUNCTIONALLY RELEVANT BUGFIXES --- 461 * Let man(1) show manuals for the current architecture by default, 462 and support the MACHINE environment variable. 463 * Fix the man(1) and apropos(1) -m option, it didn't work at all. 464 * Do not spawn a pager when there is no output. 465 * In makewhatis(8), fix detection of hardlinked manuals on platforms 466 having padding in struct inodev (typically 64bit platforms). 467 --- PORTABILITY IMPROVEMENTS --- 468 * Ignore O_CLOEXEC when the operating system doesn't provide it. 469 * Avoid forward reference to enum type which violates ISO C99. 470 * Support homebrew-style linking on Mac OS X. 471 --- MINOR NEW FEATURES --- 472 * lookup: Accept digit+letter and "n" as section names in man(1), 473 and consistently handle digit+letter in file name extensions. 474 * lookup: Speed up -s/-S by using the "mlinks" rather than the "keys" table. 475 * output: Insert horizontal lines between formatted manual pages. 476 * input: New stricter and more resilient UTF-8 parser. 477 * mdoc(7): Refactor block rewinding for simpler and more robust parsing. 478 * man(7): Use the -Ios option when .TH has less than four arguments. 479 * tbl(7): Implement the "center" option. 480 * tbl(7): New option and format parsers, improved in many respects. 481 * roff(7): Basic implementation of the \o escape sequence (overstrike), 482 and improved rendering of overstrikes in PostScript and PDF output. 483 * Message improvements, in particular for, but not restricted to, 484 eqn(7), tbl(7), and wrong numbers of arguments in mdoc(7) and man(7), 485 in various cases also improving output generated by invalid input. 486 * Delete the -V option.

and MathML output, and various other code contributions. 616 * Jonathan Gray (OpenBSD) for extensive testing with afl (the 617 American Fuzzy Lop security fuzzer) resulting in many bug reports. 618 * Anthony Bentley (OpenBSD), Baptiste Daroussin (FreeBSD), Daniel 619 Dickman, Doug Hogan, Jason McIntyre, Theo de Raadt (OpenBSD), 620 and Martin Natano for source code patches. 621 * Carsten Kunze (Heirloom troff), Daniel Levai (Slackware), 622 Garrett D'Amore (illumos), Giovanni Becchis, Matthew Dempsky, 623 Stuart Henderson, Ted Unangst, Todd Miller (OpenBSD), Thomas 624 Klausner (NetBSD), Ulrich Spoerlein (FreeBSD), Justin Haynes, 625 Marcus Merighi, Sebastien Marie, Steffen Nurpmeso and Theo Buehler 626 for bug reports. 627 628Changes in version 1.13.1, released on August 10, 2014 629 630 --- MAJOR NEW FEATURES --- 631 * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite 632 based on SQLite3 is now included. 633 * The roff(7) parser now provides an almost complete implementation 634 of numerical expressions. 635 * Warning and error messages have been improved in many ways. 636 Almost all fatal errors were downgraded to normal errors and some 637 even to warnings. Almost all messages now mention the macro where 638 the issue is detected and many indicate the workaround employed. 639 The mandoc(1) manual now includes a list explaining all messages. 640 --- MINOR NEW FEATURES --- 641 * The roff(7) parser now supports the .ami (append to macro with 642 indirectly specified name), .as (append to user-defined 643 string), .dei (define macro with indirectly specified name), 644 .ll (line length), and .rr (remove register) requests. 645 * The roff(7) parser now supports string comparison and numerical 646 conditionals in the .if and .ie requests. 647 * The roff parser now fully supports the \B (validate numerical 648 expression) and partially supports the \w (measure text width) 649 escape sequences. 650 * The terminal formatter now supports the \: (optional line break) 651 escape sequence. 652 * The roff parser now supports expansion of user-defined strings 653 involving indirect references. 654 * The roff(7) parser now handles some pre-defined read-only 655 number registers that occur in the pod2man(1) preamble. 656 * For backward compatibility, the mdoc(7) parser and formatters 657 now support the obsolete macros .En, .Es, .Fr, and .Ot. 658 * The mdoc(7) formatter non partially supports .Bd -centered. 659 * tbl(7) now handles leading and trailing vertical lines. 660 * The build system now provides fallback versions of strcasestr(3) 661 and strsep(3) for systems lacking them. 662 * The mdoc(7) manual now explains how various standards 663 supported by the .St macro are related to each other. 664 --- BUGFIXES --- 665 * In the roff(7) parser, several bugs were fixed with respect 666 to closing conditional blocks on macro lines. 667 * Parsing of roff(7) identifiers and escape sequences was improved 668 in multiple respects. 669 * In the mdoc(7) parser, the handling of defective document 670 prologues was improved in multiple ways. 671 * The mdoc(7) parser no longer skips content before the first section 672 header, and it no longer deletes non-.% content from .Rs blocks. 673 * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers. 674 * In the mdoc(7) parser, handling of .Sm with missing or invalid 675 arguments was corrected. 676 * In the mdoc(7) parser, trailing punctuation at the end of partial 677 implicit macros no longer triggers end-of-sentence spacing. 678 * In the terminal formatter, two crashes were fixed: one triggered by 679 excessive indentation and another by excessively long .Nm arguments. 680 * In the terminal formatter, a floating point rounding bug was 681 fixed that sometimes caused an off-by-one error in indentation. 682 * In the UTF-8 formatter, rendering of accents, breakable hyphens, 683 and non-breakable spaces was corrected. 684 * In the HTML formatter, encoding of special characters was 685 corrected in multiple respects. 686 * In the mdoc(7) formatter, rendering of .Ex and .Rv was 687 improved for various edge cases. 688 * In the mdoc(7) formatter, handling of empty .Bl -inset item 689 heads was improved. 690 * In the man(7) formatter, some bugs were fixed with respect 691 to same-line detection in the context of .TP and .nf macros, 692 and the indentation of .IP and .TP blocks was improved. 693 * The mandoc(3) library no longer prints to stderr. 694 --- THANKS TO --- 695 Abhinav Upadhyay (NetBSD), Andreas Voegele, Anthony Bentley (OpenBSD), 696 Christian Weisgerber (OpenBSD), Havard Eidnes (NetBSD), Jan Stary, 697 Jason McIntyre (OpenBSD), Jeremie Courreges-Anglas (OpenBSD), 698 Joerg Sonnenberger (NetBSD), Juan Francisco Cantero Hurtado (OpenBSD), 699 Marc Espie (OpenBSD), Matthias Scheler (NetBSD), Pascal Stumpf (OpenBSD), 700 Paul Onyschuk (Alpine Linux), Sebastien Marie, Steffen Nurpmeso, 701 Stuart Henderson (OpenBSD), Ted Unangst (OpenBSD), Theo de Raadt (OpenBSD), 702 Thomas Klausner (NetBSD), and Ulrich Spoerlein (FreeBSD) 703 for reporting bugs and missing features. 704 705Changes in version 1.12.3, released on December 31, 2013 706 707 * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation 708 now work correctly for .Fo/.Fa/.Fc and .Fn blocks. 709 Thanks to Franco Fichtner for doing part of the work. 710 * The mdoc(7) .Bk macro got some addititonal bugfixes. 711 * In mdoc(7) macro arguments, double quotes can now be quoted 712 by doubling them, just like in man(7). 713 Thanks to Tsugutomo ENAMI for the patch. 714 * At the end of man(7) macro lines, end-of-sentence spacing 715 now works. Thanks to Franco Fichtner for the patch. 716 * For backward compatibility, the man(7) parser now supports the 717 man-ext .UR/.UE (uniform resource identifier) block macros. 718 * The man(7) parser now handles closing blocks that are not open 719 more gracefully. 720 * The man(7) parser now ignores blank lines right after .SH and .SS. 721 * In the man(7) formatter, reset indentation when leaving a block, 722 not just when entering the next one. 723 * The roff(7) .nr request now supports incrementing and decrementing 724 number registers and stops parsing the number right before the 725 first non-digit character. 726 * The roff(7) parser now supports the alternative escape sequence 727 syntax \C'uXXXX' for Unicode characters. 728 * The roff(7) parser now parses and ignores the .fam (font family) 729 and .hw (hyphenation points) requests and the \d and \u escape 730 sequences. 731 * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE. 732 733Changes in version 1.12.2, released on Oktober 5, 2013 734 735 * The mdoc(7) to man(7) converter, to be called as mandoc -Tman, 736 is now fully functional. 737 * The mandoc(1) utility now supports the -Ios (default operating system) 738 input option, and the -Tutf8 output mode now actually works. 739 * The mandocdb(8) utility no longer truncates existing databases when 740 starting to build new ones, but only replaces them when the build 741 actually succeeds. 742 * The man(7) parser now supports the PD macro (paragraph distance), 743 and (for GNU man-ext compatibility only) EX (example block) and EE 744 (example end). Plus several bugfixes regarding indentation, line 745 breaks, and vertical spacing, and regarding RS following TP. 746 * The roff(7) parser now supports the \f(BI (bold+italic) font escape, 747 the \z (zero cursor advance) escape and the cc (change control 748 character) and it (input line trap) requests. Plus bugfixes regarding 749 the \t (tab) escape, nested escape sequences, and conditional requests. 750 * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting 751 enclosures, delimiter handling, list indentation and horizontal and 752 vertical spacing, formatting of the Lk, %U, and %C macros, plus some 753 bugfixes related to the handling of syntax errors like badly nested 754 font blocks, stray Ta macros outside column lists, unterminated It Xo 755 blocks, and non-text children of Nm blocks. 756 * In tbl(7), the width of horizontal spans and the vertical spacing 757 around tables was corrected, and in man(7) files, a crash was fixed 758 that was triggered by some particular unclosed T{ macros. 759 * For mandoc developers, we now provide a tbl(3) library manual and 760 gmdiff, a very small, very simplistic groff-versus-mandoc output 761 comparison tool. 762 * Provide this NEWS file. 763 764Changes in version 1.12.1, released on March 23, 2012 765 766 * Significant work on apropos(1) and mandocdb(8). These tools are now 767 much more robust. A whatis(1) implementation is now handled as an 768 apropos(1) mode. These tools are also able to minimally handle 769 pre-formatted pages, that is, those already formatted by another 770 utility such as GNU troff. 771 * The man.cgi(7) script is also now available for wider testing. 772 It interfaces with mandocdb(8) manuals cached by catman(8). 773 HTML output is generated on-the-fly by libmandoc or internal 774 methods to convert pre-formatted pages. 775 * The mailing list archive for the discuss and tech lists are being 776 hosted by Gmane at gmane.comp.tools.mdocml.user and 777 gmane.comp.tools.mdocml.devel, respectively. 778 779Changes in version 1.12.0, released on October 8, 2011 780 781 * This version features a new, work-in-progress mandoc(1) output mode: 782 -Tman. This mode allows a system maintainer to distribute man(7) 783 media for older systems that may not natively support mdoc(7), such 784 as old Solaris systems. 785 * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes. 786 * While adding features, an apropos(1) utility has been merged from the 787 mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic 788 search of manual content. apropos(1) is different from the traditional 789 apropos primarily in allowing keyword search (such as for functions, 790 utilities, etc.) and regular expressions. Note that the calling 791 syntax for apropos is likely to change as it settles down. 792 * In documentation news, the mdoc(7) and man(7) manuals have been 793 made considerably more readable by adding MACRO OVERVIEW sections, by 794 moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual, 795 and by moving the very technical MACRO SYNTAX sections down to the 796 bottom of the page. 797 * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables 798 was rewritten completely. It is now compatible with groff(1), both 799 with and without frames and rulers. 800 * Nesting of indented blocks is now supported in man(7), and several 801 bugs were fixed regarding indentation and alignment. 802 * The page headers in mdoc(7) are now nicer for very long titles. 803 804Changes in version 1.11.7, released on September 2, 2011 805 806 * Added demandoc(1) utility for stripping away macros and escapes. 807 This replaces the historical deroff(1) utility. 808 * Also improved the mdoc(7) and man(7) manuals. 809 810Changes in version 1.11.6, released on August 16, 2011 811 812 * Handling of tr macro in roff(7) implemented. This makes Perl 813 documentation much more readable. Hyphenation is also now enabled in 814 man(7) format documents. Many other general improvements have been 815 implemented. 816 817Changes in version 1.11.5, released on July 24, 2011 818 819 * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn 820 input (although few GNU extensions are accepted, nor is mixing 821 low-level roff with eqn). See the eqn(7) manual for details. 822 For the time being, equations are rendered as simple in-line text. 823 The equation parser satisfies the language specified in the 824 Second Edition User's Guide: 825 http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps 826 827Changes in version 1.11.4, released on July 12, 2011 828 829 * Bug-fixes and clean-ups across all systems, especially in mandocdb(8) 830 and the man(7) parser. This release was significantly assisted by 831 participants in OpenBSD's c2k11. Thanks! 832 833Changes in version 1.11.3, released on May 26, 2011 834 835 * Introduce locale-encoding of output with the -Tlocale output option and 836 Unicode escaped-character input. See mandoc(1) and mandoc_char(7), 837 respectively, for details. This allows for non-ASCII characters (e.g., 838 \[u5000]) to be rendered in the locale's encoding, if said environment 839 supports wide-character encoding (if it does not, -Tascii is used 840 instead). Locale support can be turned off at compile time by removing 841 -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym 842 for -Tascii. 843 * Furthermore, multibyte-encoded documents, such as those in UTF-8, may 844 be on-the-fly recoded into mandoc(1) input by using the newly-added 845 preconv(1) utility. Note: in the future, this feature may be 846 integrated into mandoc(1). 847 848Changes in version 1.11.2, released on May 12, 2011 849 850 * Corrected some installation issues in version 1.11.1. 851 * Further migration to libmandoc. 852 * Initial public release (this utility is very much under development) 853 of mandocdb(8). This utility produces keyword databases of manual 854 content, which features semantic querying of manual content. 855 856Changes in version 1.11.1, released on April 4, 2011 857 858 * The earlier libroff, libmdoc, and libman soup have been merged into 859 a single library, libmandoc, which manages all aspects of parsing 860 real manuals, from line-handling to tbl(7) parsing. 861 * As usual, many general fixes and improvements have also occurred. 862 In particular, a great deal of redundancy and superfluous code has 863 been removed with the merging of the backend libraries. 864 * see also the changes in 1.10.10 865 866Changes in version 1.10.10, March 20, 2011, NOT released 867 868 * Initial eqn(7) functionality is in place. For the time being, 869 this is limited to the recognition of equation blocks; 870 future version of mdocml will expand upon this framework. 871 872Changes in version 1.10.9, released on January 7, 2011 873 874 * Many back-end fixes have been implemented: argument handling (quoting), 875 man(7) improvements, error/warning classes, and many more. 876 * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in 877 the roff(7) manual) has been merged from tbl.bsd.lv. Output is still 878 minimal, especially for -Thtml and -Txhtml, but manages to at least 879 display data. This means that mandoc(1) now has built-in support 880 for two troff preprocessors via libroff: soelim(1) and tbl(1). 881 882Changes in version 1.10.8, released on December 24, 2010 883 884 * Overhauled the -Thtml and -Txhtml output modes. They now display 885 readable output in arbitrary browsers, including text-based ones like 886 lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section 887 for examples. Attention: available style-sheet classes have been 888 considerably changed! See the example.style.css file for details. 889 Lastly, libmdoc and libman have been cleaned up and reduced in size 890 and complexity. 891 * see also the changes in 1.10.7 892 893Changes in version 1.10.7, December 6, 2010, NOT released 894 895 Significant improvements merged from OpenBSD downstream, including: 896 * many new roff(7) components, 897 * in-line implementation of troff's soelim(1), 898 * broken-block handling, 899 * overhauled error classifications, and 900 * cleaned up handling of error conditions. 901 902Changes in version 1.10.6, released on September 27, 2010 903 904 * Calling conventions for mandoc(1) have changed: -W improved and -f 905 deprecated. 906 * Non-ASCII characters are also now uniformly discarded. 907 * Lots of documentation improvements. 908 * Many incremental fixes accomodating for groff's more interesting 909 productions. 910 * Lastly, pod2man(1) preambles are now fully accepted after some 911 considerable roff(7) and special character support. 912 913Changes in version 1.10.5, released on July 27, 2010 914 915 * Primarily a bug-fix and polish release, but including -Tpdf support 916 in mandoc(1) by way of "Summer of Code". Highlights: 917 * fix "Sm" and "Bd" handling 918 * fix end-of-sentence handling for embedded sentences 919 * polish man(7) documentation 920 * document all mdoc(7) macros 921 * polish mandoc(1) -Tps output 922 * lots of internal clean-ups in character escapes 923 * un-break literal contexts in man(7) documents 924 * improve -Thtml output for -man 925 * add mandoc(1) -Tpdf support 926 927Changes in version 1.10.4, released on July 12, 2010 928 929 * Lots of features developed during both "Summer of Code" and the 930 OpenBSD c2k10 hackathon: 931 * minimal "ds" roff(7) symbols are supported 932 * beautified SYNOPSIS section output 933 * acceptance of scope-block breakage in mdoc(7) 934 * clarify error message status 935 * many minor bug-fixes and formatting issues resolved 936 * see also changes in 1.10.3 937 938Changes in version 1.10.3, June 29, 2010, NOT released 939 940 * variable font-width and paper-size support in mandoc(1) -Tps output 941 * "Bk" mdoc(7) support 942 943Changes in version 1.10.2, released on June 19, 2010 944 945 * Small release featuring text-decoration in -Tps output, 946 a few minor relaxations of errors, and some optimisations. 947 948Changes in version 1.10.1, released on June 7, 2010 949 950 * This primarily focusses on the "Bl" and "It" macros described in 951 mdoc(7). Multi-line column support is now fully compatible with groff, 952 as are implicit list entries for columns. 953 * Removed manuals(7) in favour of http://manpages.bsd.lv. 954 * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation 955 in MANUAL STRUCTURE) has also been considerably simplified compared 956 to groff's method. 957 * Furthermore, the -Owidth=width output option has been added to -Tascii, 958 see mandoc(1). 959 * Lastly, initial PostScript output has been added with the -Tps option 960 to mandoc(1). It's brutally simple at the moment: fixed-font, with no 961 font decorations. 962 963Changes in version 1.10.0, released on May 29, 2010 964 965 * Release consisting of the results from the m2k10 hackathon and up-merge 966 from OpenBSD. This requires a significant note of thanks to Ingo 967 Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work, 968 and again to Joerg for hosting m2k10. Highlights (mostly cribbed from 969 Ingo's m2k10 report) follow in no particular order: 970 * a libroff preprocessor in front of libmdoc and libman stripping out 971 roff(7) instructions; 972 * end-of-sentence (EOS) detection in free-form and macro lines; 973 * correct handling of tab-separated columnar lists in mdoc(7); 974 * improved main calling routines to optionally use mmap(3) for better 975 performance; 976 * cleaned up exiting when invoked as -Tlint or over multiple files 977 with -fign-errors; 978 * error and warning message handling re-written to be unified for 979 libroff, libmdoc, and libman; 980 * handling of badly-nested explicit-scoped macros; 981 * improved free-form text parsing in libman and libmdoc; 982 * significant GNU troff compatibility improvements in -Tascii, 983 largely in terms of spacing; 984 * a regression framework for making sure the many fragilities of GNU 985 troff aren't trampled in subsequent work; 986 * support for -Tascii breaking at hyphens encountered in free-form text; 987 * and many more minor fixes and improvements 988 989Changes in version 1.9.25, released on May 13, 2010 990 991 * Fixed handling of "\*(Ba" escape. 992 * Backed out -fno-ign-chars (pointless complexity). 993 * Fixed erroneous breaking of literal lines. 994 * Fixed SYNOPSIS breaking lines before non-initial macros. 995 * Changed default section ordering. 996 * Most importantly, the framework for end-of-sentence double-spacing is 997 in place, now implemented for the "end-of-sentence, end-of-line" rule. 998 * This is a stable roll-back point before the mandoc hackathon in Rostock! 999 1000Changes in version 1.9.24, released on May 9, 2010 1001 1002 * Rolled back break-at-hyphen. 1003 * -DUGLY is now the default (no feature splits!). 1004 * Free-form text is not de-chunked any more: lines are passed 1005 whole-sale into the front-end, including whitespace. 1006 * Added mailing lists. 1007 1008Changes in version 1.9.23, released on April 7, 2010 1009 1010 * mdocml has been linked to the OpenBSD build. 1011 * This version incorporates many small changes, mostly from patches 1012 by OpenBSD, allowing crufty manuals to slip by with warnings instead 1013 of erroring-out. 1014 * Some subtle semantic issues, such as punctuation scope, have also 1015 been fixed. 1016 * Lastly, some issues with -Thtml have been fixed, which prompted an 1017 update to the online manual pages style layout. 1018 1019Changes in version 1.9.22, released on March 31, 2010 1020 1021 * Adjusted merge of the significant work by Ingo Schwarze 1022 in getting "Xo" blocks (block full implicit, e.g., "It" 1023 for non-columnar lists) to work properly. This isn't 1024 enabled by default: you must specify -DUGLY as a compiler 1025 flag (see the Makefile for details). 1026 1027Changes in version 1.9.20, released on March 30, 2010 1028 1029 * More efforts to get roff instructions in man(7) documents under 1030 control. Note that roff instructions embedded in line-scoped, 1031 next-line macros (e.g. "B") are not supported. 1032 * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a", 1033 are now correctly handled. 1034 1035Changes in version 1.9.18, released on March 27, 2010 1036 1037 * Many fixes (largely pertaining to scope) 1038 and improvements (e.g., handling of apostrophe-control macros, 1039 which fixes the strange "BR" seen in some macro output) 1040 to handling roff instructions in man(7) documents. 1041 1042Changes in version 1.9.17, released on March 25, 2010 1043 1044 * Accept perlpod(1) standard preamble. 1045 * Also accept (and discard) "de", "dei", "am", "ami", and "ig" 1046 roff macro blocks. 1047 1048Changes in version 1.9.16, released on March 22, 2010 1049 1050 * Inspired by patches and bug reports by Ingo Schwarze, 1051 allowed man(7) to accept non-printing elements to be nested 1052 within next-line scopes, such as "br" within "B" or "TH", 1053 which is valid roff. 1054 * Longsoon architecture also noted and Makefile cleaned up. 1055 1056Changes in version 1.9.15, released on February 18, 2010 1057 1058 * Moved to our new BSD.lv home. 1059 * XHTML is now an acceptable output mode for mandoc(1); 1060 * "Xr" made more compatible with groff; 1061 * "Vt" fixed when invoked in SYNOPSIS; 1062 * "\\" escape removed; 1063 * end-of-line white-space detected for all lines; 1064 * subtle bug fixed in list display for some modes; 1065 * compatibility layer checked in for compilation in diverse 1066 UNIX systems; 1067 * and column lengths handled correctly. 1068 1069For older releases, see the ChangeLog files 1070in http://mandoc.bsd.lv/snapshots/ . 1071
