1$Id: NEWS,v 1.10 2015/11/05 16:58:20 schwarze Exp $ 2 3This file lists the most important changes in the mdocml.bsd.lv distribution. 4 5Changes in version 1.13.3, released on March 13, 2015 6 7 --- MAJOR NEW FEATURES --- 8 * When a manual is missing from an outdated database, let man(1) 9 show it anyway, using a KISS file system lookup as a fallback. 10 * Use this to always provide man(1), even without database support. 11 * Fatal errors no longer exist. If a file can be opened, mandoc 12 will produce some output; at worst, the output may be almost empty. 13 * New -Wunsupp message level. 14 --- POTENTIONALLY SECURITY RELEVANT BUGFIXES --- 15 * Fix a potential write buffer overrun on incomplete string conditionals. 16 http://mdocml.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.241 17 * Fix a potential write buffer overrun on backslash at EOF in a conditional. 18 http://mdocml.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.247 19 * Fix a use after free sometimes hit when validation deletes a block. 20 http://mdocml.bsd.lv/cgi-bin/cvsweb/mdoc_macro.c#rev1.180 21 --- MAJOR FUNCTIONALLY RELEVANT BUGFIXES --- 22 * Let man(1) show manuals for the current architecture by default, 23 and support the MACHINE environment variable. 24 * Fix the man(1) and apropos(1) -m option, it didn't work at all. 25 * Do not spawn a pager when there is no output. 26 * In makewhatis(8), fix detection of hardlinked manuals on platforms 27 having padding in struct inodev (typically 64bit platforms). 28 --- PORTABILITY IMPROVEMENTS --- 29 * Ignore O_CLOEXEC when the operating system doesn't provide it. 30 * Avoid forward reference to enum type which violates ISO C99. 31 * Support homebrew-style linking on Mac OS X. 32 --- MINOR NEW FEATURES --- 33 * lookup: Accept digit+letter and "n" as section names in man(1), 34 and consistently handle digit+letter in file name extensions. 35 * lookup: Speed up -s/-S by using the "mlinks" rather than the "keys" table. 36 * output: Insert horizontal lines between formatted manual pages. 37 * input: New stricter and more resilient UTF-8 parser. 38 * mdoc(7): Refactor block rewinding for simpler and more robust parsing. 39 * man(7): Use the -Ios option when .TH has less than four arguments. 40 * tbl(7): Implement the "center" option. 41 * tbl(7): New option and format parsers, improved in many respects. 42 * roff(7): Basic implementation of the \o escape sequence (overstrike), 43 and improved rendering of overstrikes in PostScript and PDF output. 44 * Message improvements, in particular for, but not restricted to, 45 eqn(7), tbl(7), and wrong numbers of arguments in mdoc(7) and man(7), 46 in various cases also improving output generated by invalid input. 47 * Delete the -V option. It serves no purpose but keeps confusing people. 48 * gmdiff: Minimal support for Heirloom roff. 49 --- RELIABILITY BUGFIXES --- 50 * tbl(7): Fix a read buffer overrun on 'f' at EOL in a layout. 51 * roff(7): Fix a read buffer overrun on incomplete numerical conditions. 52 * mdoc(7): Fix a NULL pointer access on .Nd followed by an explicit block. 53 * mdoc(7): Fix a NULL pointer access on .It Xo without .Xc. 54 * mdoc(7): Fix a NULL pointer access on .Eo without a tail. 55 * mdoc(7): Fix a NULL pointer access in the validation of empty .St macros. 56 * man(7)/tbl(7): Fix a NULL pointer access on .TS right after .TP. 57 * tbl(7): Fix a NULL pointer access on layout lines without any cells. 58 * eqn(7): Fix NULL pointer accesses in the terminal formatter. 59 * roff(7): Fix a NULL pointer access on trailing \s-/\s+ without an argument. 60 * gz: Fix a potential NULL pointer access after waitpid() failure. 61 * roff(7): Don't let the modulo operator divide by zero. 62 * input: Fix an assertion failure on certain invalid UTF-8 input. 63 * terminal output: Allow arbitrary depth of the font stack (assertion fix). 64 * mdoc(7): Fix assertion failures and endless loops on invalid block closing. 65 * mdoc(7): Fix an assertion failure on .Bl .Sm not followed by .It. 66 * mdoc(7): Fix an assertion failure on .Bl -column ... .El .Ta. 67 * tbl(7): Fix assertion failures by macros inside table data, 68 but do not throw away the macro arguments. 69 * Prevent certain kinds of unreasonable input from producing excessive 70 output, in one case caused by unsigned integer underflow. 71 * Fix a potential memory leak in makewhatis(8) on very long filenames. 72 --- MINOR BUGFIXES --- 73 * mdoc(7): Fix parsing of badly nested blocks with multiple identical blocks. 74 * mdoc(7): Support negative indentations for displays and lists. 75 * mdoc(7): Don't mistreat negative .sp arguments as large positive ones. 76 * mdoc(7): Some spacing fixes for .Eo/.Ec. 77 * man(7): Support negative horizontal widths. 78 * man(7): Do not print out invalid .IP arguments. 79 * man(7): Correctly handle scaling units after .PD. 80 * man(7): Support .RE with an argument. 81 * man(7): Fix restoring

Fix vertical scaling, most of it was wrong. 88 * roff(7): Slightly improve \w width measurements. 89 * roff(7): Accept the historic aliases \s10 to \s39 for \s(10 to \s(39. 90 * roff(7): Correctly escape quotes when expanding macro arguments. 91 * roff(7): Correctly handle scaling units in numerical expressions, 92 and some other improvements to the parsing of numerical expressions. 93 * roff(7): Three minor fixes with respect to evaluation of conditionals. 94 * roff(7): Let .it accept numerical expressions, not just constants. 95 * mandoc_char(7): Correct some character names and renderings. 96 * If earlier files set a non-zero exit status, never reset it to zero. 97 --- THANKS TO --- 98 * Jonathan Gray (OpenBSD) for yet more testing with afl (the American 99 Fuzzy Lop security fuzzer), again resulting in many bug reports. 100 * Theo de Raadt (OpenBSD) for suggesting the main new feature (man(1) file 101 system lookup) and for reporting an important bug (pager

customizations. 138 * Autodetect wchar, sqlite3, and manpath support. 139 * Provide a fallback version of fts(3) for systems lacking it. 140 * Support choosing alternative binary and manual names. 141 --- MINOR NEW FEATURES --- 142 * Rudimentary implementation of the e, x, and z tbl(7) layout 143 modifiers to equalize, maximize, and ignore the width of columns. 144 * Implement font modifiers in tbl(7) layouts. 145 * Allow comma-separated options in the tbl(7) options line. 146 * Parse and ignore the .pl (page length) roff(7) request. 147 * Implement .An -[no]split for the mdoc(7) -Thtml output mode. 148 * Support bold italic font in PostScript and PDF output. 149 * Warn about commas in function arguments and parentheses in function names. 150 * Warn about botched .Xr ordering and punctuation below SEE ALSO. 151 * Warn about AUTHORS sections without .An macros. 152 * Warn about attempts to call non-callable macros. 153 * New developer documentation manual page mandoc_headers(3). 154 --- BUGFIXES --- 155 * Fix read buffer overrun sometimes triggered by trailing whitespace. 156 * Fix read buffer overrun triggered by certain invalid \H sequences. 157 * Fix

Fix NULL pointer access triggered by missing .Nm. 161 * Fix an assertion triggered by .It right after .El. 162 * Fix an assertion triggered by .Ec without preceding .Eo. 163 * Fix an assertion triggered by .Sm or .Db with multiple arguments. 164 * Fix assertion failures triggered by very large width arguments. 165 * Fix a division by zero in the roff(7) parser. 166 * Prevent negative arguments to .ll from causing integer underflow. 167 * Correctly autodetect source format even when .Dd is preceded by .ll. 168 * Multiple fixes with respect to .Bd and .Bl -offset and -width. 169 * Many bugfixes with respect to scaling units. 170 * Multiple fixes with respect to delimiter handling by in-line macros. 171 * Multiple fixes with respect to .Pf. 172 * Make \c work properly in no-fill mode. 173 * Stricter syntax checking of Unicode character names. 174 --- THANKS TO --- 175 * Kristaps Dzonsons for rewriting the eqn(7) parser, implementing 176 HTML5 and MathML output, and various other code contributions. 177 * Jonathan Gray (OpenBSD) for extensive testing with afl (the 178 American Fuzzy Lop security fuzzer) resulting in many bug reports. 179 * Anthony Bentley (OpenBSD), Baptiste Daroussin (FreeBSD), Daniel 180 Dickman, Doug Hogan, Jason McIntyre, Theo de Raadt (OpenBSD), 181 and Martin Natano for source code patches. 182 * Carsten Kunze (Heirloom troff), Daniel Levai (Slackware), 183 Garrett D'Amore (illumos), Giovanni Becchis, Matthew Dempsky, 184 Stuart Henderson, Ted Unangst, Todd Miller (OpenBSD), Thomas 185 Klausner (NetBSD), Ulrich Spoerlein (FreeBSD), Justin Haynes, 186 Marcus Merighi, Sebastien Marie, Steffen Nurpmeso and Theo Buehler 187 for bug reports. 188 189Changes in version 1.13.1, released on August 10, 2014 190 191 --- MAJOR NEW FEATURES --- 192 * A complete apropos(1)/makewhatis(8)/man.cgi(8) suite 193 based on SQLite3 is now included. 194 * The roff(7) parser now provides an almost complete implementation 195 of numerical expressions. 196 * Warning and error messages have been improved in many ways. 197 Almost all fatal errors were downgraded to normal errors and some 198 even to warnings. Almost all messages now mention the macro where 199 the issue is detected and many indicate the workaround employed. 200 The mandoc(1) manual now includes a list explaining all messages. 201 --- MINOR NEW FEATURES --- 202 * The roff(7) parser now supports the .ami (append to macro with 203 indirectly specified name), .as (append to user-defined 204 string), .dei (define macro with indirectly specified name), 205 .ll (line length), and .rr (remove register) requests. 206 * The roff(7) parser now supports string comparison and numerical 207 conditionals in the .if and .ie requests. 208 * The roff parser now fully supports the \B (validate numerical 209 expression) and partially supports the \w (measure text width) 210 escape sequences. 211 * The terminal formatter now supports the \: (optional line break) 212 escape sequence. 213 * The roff parser now supports expansion of user-defined strings 214 involving indirect references. 215 * The roff(7) parser now handles some pre-defined read-only 216 number registers that occur in the pod2man(1) preamble. 217 * For backward compatibility, the mdoc(7) parser and formatters 218 now support the obsolete macros .En, .Es, .Fr, and .Ot. 219 * The mdoc(7) formatter non partially supports .Bd -centered. 220 * tbl(7) now handles leading and trailing vertical lines. 221 * The build system now provides fallback versions of strcasestr(3) 222 and strsep(3) for systems lacking them. 223 * The mdoc(7) manual now explains how various standards 224 supported by the .St macro are related to each other. 225 --- BUGFIXES --- 226 * In the roff(7) parser, several bugs were fixed with respect 227 to closing conditional blocks on macro lines. 228 * Parsing of roff(7) identifiers and escape sequences was improved 229 in multiple respects. 230 * In the mdoc(7) parser, the handling of defective document 231 prologues was improved in multiple ways. 232 * The mdoc(7) parser no longer skips content before the first section 233 header, and it no longer deletes non-.% content from .Rs blocks. 234 * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers. 235 * In the mdoc(7) parser, handling of .Sm with missing or invalid 236 arguments was corrected. 237 * In the mdoc(7) parser, trailing punctuation at the end of partial 238 implicit macros no longer triggers end-of-sentence spacing. 239 * In the terminal formatter, two crashes were fixed: one triggered by 240 excessive indentation and another by excessively long .Nm arguments. 241 * In the terminal formatter, a floating point rounding bug was 242 fixed that sometimes caused an off-by-one error in indentation. 243 * In the UTF-8 formatter, rendering of accents, breakable hyphens, 244 and non-breakable spaces was corrected. 245 * In the HTML formatter, encoding of special characters was 246 corrected in multiple respects. 247 * In the mdoc(7) formatter, rendering of .Ex and .Rv was 248 improved for various edge cases. 249 * In the mdoc(7) formatter, handling of empty .Bl -inset item 250 heads was improved. 251 * In the man(7) formatter, some bugs were fixed with respect 252 to same-line detection in the context of .TP and .nf macros, 253 and the indentation of .IP and .TP blocks was improved. 254 * The mandoc(3) library no longer prints to stderr. 255 --- THANKS TO --- 256 Abhinav Upadhyay (NetBSD), Andreas Voegele, Anthony Bentley (OpenBSD), 257 Christian Weisgerber (OpenBSD), Havard Eidnes (NetBSD), Jan Stary, 258 Jason McIntyre (OpenBSD), Jeremie Courreges-Anglas (OpenBSD), 259 Joerg Sonnenberger (NetBSD), Juan Francisco Cantero Hurtado (OpenBSD), 260 Marc Espie (OpenBSD), Matthias Scheler (NetBSD), Pascal Stumpf (OpenBSD), 261 Paul Onyschuk (Alpine Linux), Sebastien Marie, Steffen Nurpmeso, 262 Stuart Henderson (OpenBSD), Ted Unangst (OpenBSD), Theo de Raadt (OpenBSD), 263 Thomas Klausner (NetBSD), and Ulrich Spoerlein (FreeBSD) 264 for reporting bugs and missing features. 265 266Changes in version 1.12.3, released on December 31, 2013 267 268 * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation 269 now work correctly for .Fo/.Fa/.Fc and .Fn blocks. 270 Thanks to Franco Fichtner for doing part of the work. 271 * The mdoc(7) .Bk macro got some addititonal bugfixes. 272 * In mdoc(7) macro arguments, double quotes can now be quoted 273 by doubling them, just like in man(7). 274 Thanks to Tsugutomo ENAMI for the patch. 275 * At the end of man(7) macro lines, end-of-sentence spacing 276 now works. Thanks to Franco Fichtner for the patch. 277 * For backward compatibility, the man(7) parser now supports the 278 man-ext .UR/.UE (uniform resource identifier) block macros. 279 * The man(7) parser now handles closing blocks that are not open 280 more gracefully. 281 * The man(7) parser now ignores blank lines right after .SH and .SS. 282 * In the man(7) formatter, reset indentation when leaving a block, 283 not just when entering the next one. 284 * The roff(7) .nr request now supports incrementing and decrementing 285 number registers and stops parsing the number right before the 286 first non-digit character. 287 * The roff(7) parser now supports the alternative escape sequence 288 syntax \C'uXXXX' for Unicode characters. 289 * The roff(7) parser now parses and ignores the .fam (font family) 290 and .hw (hyphenation points) requests and the \d and \u escape 291 sequences. 292 * The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE. 293 294Changes in version 1.12.2, released on Oktober 5, 2013 295 296 * The mdoc(7) to man(7) converter, to be called as mandoc -Tman, 297 is now fully functional. 298 * The mandoc(1) utility now supports the -Ios (default operating system) 299 input option, and the -Tutf8 output mode now actually works. 300 * The mandocdb(8) utility no longer truncates existing databases when 301 starting to build new ones, but only replaces them when the build 302 actually succeeds. 303 * The man(7) parser now supports the PD macro (paragraph distance), 304 and (for GNU man-ext compatibility only) EX (example block) and EE 305 (example end). Plus several bugfixes regarding indentation, line 306 breaks, and vertical spacing, and regarding RS following TP. 307 * The roff(7) parser now supports the \f(BI (bold+italic) font escape, 308 the \z (zero cursor advance) escape and the cc (change control 309 character) and it (input line trap) requests. Plus bugfixes regarding 310 the \t (tab) escape, nested escape sequences, and conditional requests. 311 * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting 312 enclosures, delimiter handling, list indentation and horizontal and 313 vertical spacing, formatting of the Lk, %U, and %C macros, plus some 314 bugfixes related to the handling of syntax errors like badly nested 315 font blocks, stray Ta macros outside column lists, unterminated It Xo 316 blocks, and non-text children of Nm blocks. 317 * In tbl(7), the width of horizontal spans and the vertical spacing 318 around tables was corrected, and in man(7) files, a crash was fixed 319 that was triggered by some particular unclosed T{ macros. 320 * For mandoc developers, we now provide a tbl(3) library manual and 321 gmdiff, a very small, very simplistic groff-versus-mandoc output 322 comparison tool. 323 * Provide this NEWS file. 324 325Changes in version 1.12.1, released on March 23, 2012 326 327 * Significant work on apropos(1) and mandocdb(8). These tools are now 328 much more robust. A whatis(1) implementation is now handled as an 329 apropos(1) mode. These tools are also able to minimally handle 330 pre-formatted pages, that is, those already formatted by another 331 utility such as GNU troff. 332 * The man.cgi(7) script is also now available for wider testing. 333 It interfaces with mandocdb(8) manuals cached by catman(8). 334 HTML output is generated on-the-fly by libmandoc or internal 335 methods to convert pre-formatted pages. 336 * The mailing list archive for the discuss and tech lists are being 337 hosted by Gmane at gmane.comp.tools.mdocml.user and 338 gmane.comp.tools.mdocml.devel, respectively. 339 340Changes in version 1.12.0, released on October 8, 2011 341 342 * This version features a new, work-in-progress mandoc(1) output mode: 343 -Tman. This mode allows a system maintainer to distribute man(7) 344 media for older systems that may not natively support mdoc(7), such 345 as old Solaris systems. 346 * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes. 347 * While adding features, an apropos(1) utility has been merged from the 348 mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic 349 search of manual content. apropos(1) is different from the traditional 350 apropos primarily in allowing keyword search (such as for functions, 351 utilities, etc.) and regular expressions. Note that the calling 352 syntax for apropos is likely to change as it settles down. 353 * In documentation news, the mdoc(7) and man(7) manuals have been 354 made considerably more readable by adding MACRO OVERVIEW sections, by 355 moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual, 356 and by moving the very technical MACRO SYNTAX sections down to the 357 bottom of the page. 358 * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables 359 was rewritten completely. It is now compatible with groff(1), both 360 with and without frames and rulers. 361 * Nesting of indented blocks is now supported in man(7), and several 362 bugs were fixed regarding indentation and alignment. 363 * The page headers in mdoc(7) are now nicer for very long titles. 364 365Changes in version 1.11.7, released on September 2, 2011 366 367 * Added demandoc(1) utility for stripping away macros and escapes. 368 This replaces the historical deroff(1) utility. 369 * Also improved the mdoc(7) and man(7) manuals. 370 371Changes in version 1.11.6, released on August 16, 2011 372 373 * Handling of tr macro in roff(7) implemented. This makes Perl 374 documentation much more readable. Hyphenation is also now enabled in 375 man(7) format documents. Many other general improvements have been 376 implemented. 377 378Changes in version 1.11.5, released on July 24, 2011 379 380 * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn 381 input (although few GNU extensions are accepted, nor is mixing 382 low-level roff with eqn). See the eqn(7) manual for details. 383 For the time being, equations are rendered as simple in-line text. 384 The equation parser satisfies the language specified in the 385 Second Edition User's Guide: 386 http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps 387 388Changes in version 1.11.4, released on July 12, 2011 389 390 * Bug-fixes and clean-ups across all systems, especially in mandocdb(8) 391 and the man(7) parser. This release was significantly assisted by 392 participants in OpenBSD's c2k11. Thanks! 393 394Changes in version 1.11.3, released on May 26, 2011 395 396 * Introduce locale-encoding of output with the -Tlocale output option and 397 Unicode escaped-character input. See mandoc(1) and mandoc_char(7), 398 respectively, for details. This allows for non-ASCII characters (e.g., 399 \[u5000]) to be rendered in the locale's encoding, if said environment 400 supports wide-character encoding (if it does not, -Tascii is used 401 instead). Locale support can be turned off at compile time by removing 402 -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym 403 for -Tascii. 404 * Furthermore, multibyte-encoded documents, such as those in UTF-8, may 405 be on-the-fly recoded into mandoc(1) input by using the newly-added 406 preconv(1) utility. Note: in the future, this feature may be 407 integrated into mandoc(1). 408 409Changes in version 1.11.2, released on May 12, 2011 410 411 * Corrected some installation issues in version 1.11.1. 412 * Further migration to libmandoc. 413 * Initial public release (this utility is very much under development) 414 of mandocdb(8). This utility produces keyword databases of manual 415 content, which features semantic querying of manual content. 416 417Changes in version 1.11.1, released on April 4, 2011 418 419 * The earlier libroff, libmdoc, and libman soup have been merged into 420 a single library, libmandoc, which manages all aspects of parsing 421 real manuals, from line-handling to tbl(7) parsing. 422 * As usual, many general fixes and improvements have also occurred. 423 In particular, a great deal of redundancy and superfluous code has 424 been removed with the merging of the backend libraries. 425 * see also the changes in 1.10.10 426 427Changes in version 1.10.10, March 20, 2011, NOT released 428 429 * Initial eqn(7) functionality is in place. For the time being, 430 this is limited to the recognition of equation blocks; 431 future version of mdocml will expand upon this framework. 432 433Changes in version 1.10.9, released on January 7, 2011 434 435 * Many back-end fixes have been implemented: argument handling (quoting), 436 man(7) improvements, error/warning classes, and many more. 437 * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in 438 the roff(7) manual) has been merged from tbl.bsd.lv. Output is still 439 minimal, especially for -Thtml and -Txhtml, but manages to at least 440 display data. This means that mandoc(1) now has built-in support 441 for two troff preprocessors via libroff: soelim(1) and tbl(1). 442 443Changes in version 1.10.8, released on December 24, 2010 444 445 * Overhauled the -Thtml and -Txhtml output modes. They now display 446 readable output in arbitrary browsers, including text-based ones like 447 lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section 448 for examples. Attention: available style-sheet classes have been 449 considerably changed! See the example.style.css file for details. 450 Lastly, libmdoc and libman have been cleaned up and reduced in size 451 and complexity. 452 * see also the changes in 1.10.7 453 454Changes in version 1.10.7, December 6, 2010, NOT released 455 456 Significant improvements merged from OpenBSD downstream, including: 457 * many new roff(7) components, 458 * in-line implementation of troff's soelim(1), 459 * broken-block handling, 460 * overhauled error classifications, and 461 * cleaned up handling of error conditions. 462 463Changes in version 1.10.6, released on September 27, 2010 464 465 * Calling conventions for mandoc(1) have changed: -W improved and -f 466 deprecated. 467 * Non-ASCII characters are also now uniformly discarded. 468 * Lots of documentation improvements. 469 * Many incremental fixes accomodating for groff's more interesting 470 productions. 471 * Lastly, pod2man(1) preambles are now fully accepted after some 472 considerable roff(7) and special character support. 473 474Changes in version 1.10.5, released on July 27, 2010 475 476 * Primarily a bug-fix and polish release, but including -Tpdf support 477 in mandoc(1) by way of "Summer of Code". Highlights: 478 * fix "Sm" and "Bd" handling 479 * fix end-of-sentence handling for embedded sentences 480 * polish man(7) documentation 481 * document all mdoc(7) macros 482 * polish mandoc(1) -Tps output 483 * lots of internal clean-ups in character escapes 484 * un-break literal contexts in man(7) documents 485 * improve -Thtml output for -man 486 * add mandoc(1) -Tpdf support 487 488Changes in version 1.10.4, released on July 12, 2010 489 490 * Lots of features developed during both "Summer of Code" and the 491 OpenBSD c2k10 hackathon: 492 * minimal "ds" roff(7) symbols are supported 493 * beautified SYNOPSIS section output 494 * acceptance of scope-block breakage in mdoc(7) 495 * clarify error message status 496 * many minor bug-fixes and formatting issues resolved 497 * see also changes in 1.10.3 498 499Changes in version 1.10.3, June 29, 2010, NOT released 500 501 * variable font-width and paper-size support in mandoc(1) -Tps output 502 * "Bk" mdoc(7) support 503 504Changes in version 1.10.2, released on June 19, 2010 505 506 * Small release featuring text-decoration in -Tps output, 507 a few minor relaxations of errors, and some optimisations. 508 509Changes in version 1.10.1, released on June 7, 2010 510 511 * This primarily focusses on the "Bl" and "It" macros described in 512 mdoc(7). Multi-line column support is now fully compatible with groff, 513 as are implicit list entries for columns. 514 * Removed manuals(7) in favour of http://manpages.bsd.lv. 515 * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation 516 in MANUAL STRUCTURE) has also been considerably simplified compared 517 to groff's method. 518 * Furthermore, the -Owidth=width output option has been added to -Tascii, 519 see mandoc(1). 520 * Lastly, initial PostScript output has been added with the -Tps option 521 to mandoc(1). It's brutally simple at the moment: fixed-font, with no 522 font decorations. 523 524Changes in version 1.10.0, released on May 29, 2010 525 526 * Release consisting of the results from the m2k10 hackathon and up-merge 527 from OpenBSD. This requires a significant note of thanks to Ingo 528 Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work, 529 and again to Joerg for hosting m2k10. Highlights (mostly cribbed from 530 Ingo's m2k10 report) follow in no particular order: 531 * a libroff preprocessor in front of libmdoc and libman stripping out 532 roff(7) instructions; 533 * end-of-sentence (EOS) detection in free-form and macro lines; 534 * correct handling of tab-separated columnar lists in mdoc(7); 535 * improved main calling routines to optionally use mmap(3) for better 536 performance; 537 * cleaned up exiting when invoked as -Tlint or over multiple files 538 with -fign-errors; 539 * error and warning message handling re-written to be unified for 540 libroff, libmdoc, and libman; 541 * handling of badly-nested explicit-scoped macros; 542 * improved free-form text parsing in libman and libmdoc; 543 * significant GNU troff compatibility improvements in -Tascii, 544 largely in terms of spacing; 545 * a regression framework for making sure the many fragilities of GNU 546 troff aren't trampled in subsequent work; 547 * support for -Tascii breaking at hyphens encountered in free-form text; 548 * and many more minor fixes and improvements 549 550Changes in version 1.9.25, released on May 13, 2010 551 552 * Fixed handling of "\*(Ba" escape. 553 * Backed out -fno-ign-chars (pointless complexity). 554 * Fixed erroneous breaking of literal lines. 555 * Fixed SYNOPSIS breaking lines before non-initial macros. 556 * Changed default section ordering. 557 * Most importantly, the framework for end-of-sentence double-spacing is 558 in place, now implemented for the "end-of-sentence, end-of-line" rule. 559 * This is a stable roll-back point before the mandoc hackathon in Rostock! 560 561Changes in version 1.9.24, released on May 9, 2010 562 563 * Rolled back break-at-hyphen. 564 * -DUGLY is now the default (no feature splits!). 565 * Free-form text is not de-chunked any more: lines are passed 566 whole-sale into the front-end, including whitespace. 567 * Added mailing lists. 568 569Changes in version 1.9.23, released on April 7, 2010 570 571 * mdocml has been linked to the OpenBSD build. 572 * This version incorporates many small changes, mostly from patches 573 by OpenBSD, allowing crufty manuals to slip by with warnings instead 574 of erroring-out. 575 * Some subtle semantic issues, such as punctuation scope, have also 576 been fixed. 577 * Lastly, some issues with -Thtml have been fixed, which prompted an 578 update to the online manual pages style layout. 579 580Changes in version 1.9.22, released on March 31, 2010 581 582 * Adjusted merge of the significant work by Ingo Schwarze 583 in getting "Xo" blocks (block full implicit, e.g., "It" 584 for non-columnar lists) to work properly. This isn't 585 enabled by default: you must specify -DUGLY as a compiler 586 flag (see the Makefile for details). 587 588Changes in version 1.9.20, released on March 30, 2010 589 590 * More efforts to get roff instructions in man(7) documents under 591 control. Note that roff instructions embedded in line-scoped, 592 next-line macros (e.g. "B") are not supported. 593 * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a", 594 are now correctly handled. 595 596Changes in version 1.9.18, released on March 27, 2010 597 598 * Many fixes (largely pertaining to scope) 599 and improvements (e.g., handling of apostrophe-control macros, 600 which fixes the strange "BR" seen in some macro output) 601 to handling roff instructions in man(7) documents. 602 603Changes in version 1.9.17, released on March 25, 2010 604 605 * Accept perlpod(1) standard preamble. 606 * Also accept (and discard) "de", "dei", "am", "ami", and "ig" 607 roff macro blocks. 608 609Changes in version 1.9.16, released on March 22, 2010 610 611 * Inspired by patches and bug reports by Ingo Schwarze, 612 allowed man(7) to accept non-printing elements to be nested 613 within next-line scopes, such as "br" within "B" or "TH", 614 which is valid roff. 615 * Longsoon architecture also noted and Makefile cleaned up. 616 617Changes in version 1.9.15, released on February 18, 2010 618 619 * Moved to our new BSD.lv home. 620 * XHTML is now an acceptable output mode for mandoc(1); 621 * "Xr" made more compatible with groff; 622 * "Vt" fixed when invoked in SYNOPSIS; 623 * "\\" escape removed; 624 * end-of-line white-space detected for all lines; 625 * subtle bug fixed in list display for some modes; 626 * compatibility layer checked in for compilation in diverse 627 UNIX systems; 628 * and column lengths handled correctly. 629 630For older releases, see the ChangeLog files 631in http://mdocml.bsd.lv/snapshots/ . 632
