273: --- MAJOR NEW FEATURES ---
274: * In ASCII output, render mathematical symbols and greek letters

282: particular all hard-coded indentations and column widths, and
283: provide a better mandoc.css style sheet with a @media query,
284: using em units throughout, and avoiding redundancy in selectors.
285: * Better HTML output with some more fitting HTML elements, eliminating
286: needless class= attributes, and avoiding various HTML syntax errors
287: (element nesting, URL-fragment syntax, duplicate id= attributes).

295: all links in-line, even long ones.
296: * roff(7) \n+ and \n- numerical register auto-increment and -decrement
297: * roff(7) .nr optional third argument (auto-increment step size)
1.29 schwarze 298: * Autodetect in ./configure whether the compiler can use -W and -static,

933: * Parsing of roff(7) identifiers and escape sequences was improved
934: in multiple respects.
935: * In the mdoc(7) parser, the handling of defective document

939: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
940: * In the mdoc(7) parser, handling of .Sm with missing or invalid

955: heads was improved.
956: * In the man(7) formatter, some bugs were fixed with respect
957: to same-line detection in the context of .TP and .nf macros,
958: and the indentation of .IP and .TP blocks was improved.
959: * The mandoc(3) library no longer prints to stderr.

1.2 schwarze 999: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 1000:
1001: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
1002: is now fully functional.
1003: * The mandoc(1) utility now supports the -Ios (default operating system)
1004: input option, and the -Tutf8 output mode now actually works.
1005: * The mandocdb(8) utility no longer truncates existing databases when
1006: starting to build new ones, but only replaces them when the build
1007: actually succeeds.
1008: * The man(7) parser now supports the PD macro (paragraph distance),
1009: and (for GNU man-ext compatibility only) EX (example block) and EE
1010: (example end). Plus several bugfixes regarding indentation, line
1011: breaks, and vertical spacing, and regarding RS following TP.
1012: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
1013: the \z (zero cursor advance) escape and the cc (change control
1014: character) and it (input line trap) requests. Plus bugfixes regarding
1015: the \t (tab) escape, nested escape sequences, and conditional requests.
1016: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
1017: enclosures, delimiter handling, list indentation and horizontal and
1018: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
1019: bugfixes related to the handling of syntax errors like badly nested
1020: font blocks, stray Ta macros outside column lists, unterminated It Xo
1021: blocks, and non-text children of Nm blocks.
1022: * In tbl(7), the width of horizontal spans and the vertical spacing
1023: around tables was corrected, and in man(7) files, a crash was fixed
1024: that was triggered by some particular unclosed T{ macros.
1025: * For mandoc developers, we now provide a tbl(3) library manual and
1026: gmdiff, a very small, very simplistic groff-versus-mandoc output
1027: comparison tool.
1.2 schwarze 1028: * Provide this NEWS file.
1.1 schwarze 1029:
1030: Changes in version 1.12.1, released on March 23, 2012
1031:
1032: * Significant work on apropos(1) and mandocdb(8). These tools are now
1033: much more robust. A whatis(1) implementation is now handled as an
1034: apropos(1) mode. These tools are also able to minimally handle
1035: pre-formatted pages, that is, those already formatted by another
1036: utility such as GNU troff.
1037: * The man.cgi(7) script is also now available for wider testing.
1038: It interfaces with mandocdb(8) manuals cached by catman(8).
1039: HTML output is generated on-the-fly by libmandoc or internal
1040: methods to convert pre-formatted pages.
1041: * The mailing list archive for the discuss and tech lists are being
1042: hosted by Gmane at gmane.comp.tools.mdocml.user and
1043: gmane.comp.tools.mdocml.devel, respectively.
1044:
1045: Changes in version 1.12.0, released on October 8, 2011
1046:
1047: * This version features a new, work-in-progress mandoc(1) output mode:
1048: -Tman. This mode allows a system maintainer to distribute man(7)
1049: media for older systems that may not natively support mdoc(7), such
1050: as old Solaris systems.
1051: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
1052: * While adding features, an apropos(1) utility has been merged from the
1053: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
1054: search of manual content. apropos(1) is different from the traditional
1055: apropos primarily in allowing keyword search (such as for functions,
1056: utilities, etc.) and regular expressions. Note that the calling
1057: syntax for apropos is likely to change as it settles down.
1058: * In documentation news, the mdoc(7) and man(7) manuals have been
1059: made considerably more readable by adding MACRO OVERVIEW sections, by
1060: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
1061: and by moving the very technical MACRO SYNTAX sections down to the
1062: bottom of the page.
1063: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
1064: was rewritten completely. It is now compatible with groff(1), both
1065: with and without frames and rulers.
1066: * Nesting of indented blocks is now supported in man(7), and several
1067: bugs were fixed regarding indentation and alignment.
1068: * The page headers in mdoc(7) are now nicer for very long titles.
1069:
1070: Changes in version 1.11.7, released on September 2, 2011
1071:
1072: * Added demandoc(1) utility for stripping away macros and escapes.
1073: This replaces the historical deroff(1) utility.
1074: * Also improved the mdoc(7) and man(7) manuals.
1075:
1076: Changes in version 1.11.6, released on August 16, 2011
1077:
1078: * Handling of tr macro in roff(7) implemented. This makes Perl
1079: documentation much more readable. Hyphenation is also now enabled in
1080: man(7) format documents. Many other general improvements have been
1081: implemented.
1082:
1083: Changes in version 1.11.5, released on July 24, 2011
1084:
1085: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
1086: input (although few GNU extensions are accepted, nor is mixing
1087: low-level roff with eqn). See the eqn(7) manual for details.
1088: For the time being, equations are rendered as simple in-line text.
1089: The equation parser satisfies the language specified in the
1090: Second Edition User's Guide:
1091: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
1092:
1093: Changes in version 1.11.4, released on July 12, 2011
1094:
1095: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
1096: and the man(7) parser. This release was significantly assisted by
1097: participants in OpenBSD's c2k11. Thanks!
1098:
1099: Changes in version 1.11.3, released on May 26, 2011
1100:
1101: * Introduce locale-encoding of output with the -Tlocale output option and
1102: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
1103: respectively, for details. This allows for non-ASCII characters (e.g.,
1104: \[u5000]) to be rendered in the locale's encoding, if said environment
1105: supports wide-character encoding (if it does not, -Tascii is used
1106: instead). Locale support can be turned off at compile time by removing
1107: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
1108: for -Tascii.
1109: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
1110: be on-the-fly recoded into mandoc(1) input by using the newly-added
1111: preconv(1) utility. Note: in the future, this feature may be
1112: integrated into mandoc(1).
1113:
1114: Changes in version 1.11.2, released on May 12, 2011
1115:
1116: * Corrected some installation issues in version 1.11.1.
1117: * Further migration to libmandoc.
1118: * Initial public release (this utility is very much under development)
1119: of mandocdb(8). This utility produces keyword databases of manual
1120: content, which features semantic querying of manual content.
1121:
1122: Changes in version 1.11.1, released on April 4, 2011
1123:
1124: * The earlier libroff, libmdoc, and libman soup have been merged into
1125: a single library, libmandoc, which manages all aspects of parsing
1126: real manuals, from line-handling to tbl(7) parsing.
1127: * As usual, many general fixes and improvements have also occurred.
1128: In particular, a great deal of redundancy and superfluous code has
1129: been removed with the merging of the backend libraries.

1132: Changes in version 1.10.10, March 20, 2011, NOT released
1133:
1134: * Initial eqn(7) functionality is in place. For the time being,
1135: this is limited to the recognition of equation blocks;
1136: future version of mdocml will expand upon this framework.
1.1 schwarze 1137:
1138: Changes in version 1.10.9, released on January 7, 2011
1139:
1140: * Many back-end fixes have been implemented: argument handling (quoting),
1141: man(7) improvements, error/warning classes, and many more.
1142: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
1143: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
1144: minimal, especially for -Thtml and -Txhtml, but manages to at least
1145: display data. This means that mandoc(1) now has built-in support
1146: for two troff preprocessors via libroff: soelim(1) and tbl(1).
1147:
1148: Changes in version 1.10.8, released on December 24, 2010
1149:
1.3 schwarze 1150: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 1151: readable output in arbitrary browsers, including text-based ones like
1152: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
1153: for examples. Attention: available style-sheet classes have been
1154: considerably changed! See the example.style.css file for details.
1155: Lastly, libmdoc and libman have been cleaned up and reduced in size
1156: and complexity.
1.3 schwarze 1157: * see also the changes in 1.10.7
1158:
1159: Changes in version 1.10.7, December 6, 2010, NOT released
1160:
1161: Significant improvements merged from OpenBSD downstream, including:
1162: * many new roff(7) components,
1163: * in-line implementation of troff's soelim(1),
1164: * broken-block handling,
1165: * overhauled error classifications, and
1166: * cleaned up handling of error conditions.
1.1 schwarze 1167:
1168: Changes in version 1.10.6, released on September 27, 2010
1169:
1170: * Calling conventions for mandoc(1) have changed: -W improved and -f
1171: deprecated.
1172: * Non-ASCII characters are also now uniformly discarded.
1173: * Lots of documentation improvements.
1174: * Many incremental fixes accomodating for groff's more interesting
1175: productions.
1176: * Lastly, pod2man(1) preambles are now fully accepted after some
1177: considerable roff(7) and special character support.
1178:
1179: Changes in version 1.10.5, released on July 27, 2010
1180:
1181: * Primarily a bug-fix and polish release, but including -Tpdf support
1182: in mandoc(1) by way of "Summer of Code". Highlights:
1183: * fix "Sm" and "Bd" handling
1184: * fix end-of-sentence handling for embedded sentences
1185: * polish man(7) documentation
1186: * document all mdoc(7) macros
1187: * polish mandoc(1) -Tps output
1188: * lots of internal clean-ups in character escapes
1189: * un-break literal contexts in man(7) documents
1190: * improve -Thtml output for -man
1191: * add mandoc(1) -Tpdf support
1192:
1193: Changes in version 1.10.4, released on July 12, 2010
1194:
1195: * Lots of features developed during both "Summer of Code" and the
1196: OpenBSD c2k10 hackathon:
1197: * minimal "ds" roff(7) symbols are supported
1198: * beautified SYNOPSIS section output
1199: * acceptance of scope-block breakage in mdoc(7)
1200: * clarify error message status
1201: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 1202: * see also changes in 1.10.3
1203:
1204: Changes in version 1.10.3, June 29, 2010, NOT released
1205:
1206: * variable font-width and paper-size support in mandoc(1) -Tps output
1207: * "Bk" mdoc(7) support
1.1 schwarze 1208:
1209: Changes in version 1.10.2, released on June 19, 2010
1210:
1211: * Small release featuring text-decoration in -Tps output,
1212: a few minor relaxations of errors, and some optimisations.
1213:
1214: Changes in version 1.10.1, released on June 7, 2010
1215:
1216: * This primarily focusses on the "Bl" and "It" macros described in
1217: mdoc(7). Multi-line column support is now fully compatible with groff,
1218: as are implicit list entries for columns.
1219: * Removed manuals(7) in favour of http://manpages.bsd.lv.
1220: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
1221: in MANUAL STRUCTURE) has also been considerably simplified compared
1222: to groff's method.
1223: * Furthermore, the -Owidth=width output option has been added to -Tascii,
1224: see mandoc(1).
1225: * Lastly, initial PostScript output has been added with the -Tps option
1226: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
1227: font decorations.
1228:
1229: Changes in version 1.10.0, released on May 29, 2010
1230:
1231: * Release consisting of the results from the m2k10 hackathon and up-merge
1232: from OpenBSD. This requires a significant note of thanks to Ingo
1233: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
1234: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
1235: Ingo's m2k10 report) follow in no particular order:
1236: * a libroff preprocessor in front of libmdoc and libman stripping out
1237: roff(7) instructions;
1238: * end-of-sentence (EOS) detection in free-form and macro lines;
1239: * correct handling of tab-separated columnar lists in mdoc(7);
1240: * improved main calling routines to optionally use mmap(3) for better
1241: performance;
1242: * cleaned up exiting when invoked as -Tlint or over multiple files
1243: with -fign-errors;
1244: * error and warning message handling re-written to be unified for
1245: libroff, libmdoc, and libman;
1246: * handling of badly-nested explicit-scoped macros;
1247: * improved free-form text parsing in libman and libmdoc;
1248: * significant GNU troff compatibility improvements in -Tascii,
1249: largely in terms of spacing;
1250: * a regression framework for making sure the many fragilities of GNU
1251: troff aren't trampled in subsequent work;
1252: * support for -Tascii breaking at hyphens encountered in free-form text;
1253: * and many more minor fixes and improvements
1254:
1255: Changes in version 1.9.25, released on May 13, 2010
1256:
1257: * Fixed handling of "\*(Ba" escape.
1258: * Backed out -fno-ign-chars (pointless complexity).
1259: * Fixed erroneous breaking of literal lines.
1260: * Fixed SYNOPSIS breaking lines before non-initial macros.
1261: * Changed default section ordering.
1262: * Most importantly, the framework for end-of-sentence double-spacing is
1263: in place, now implemented for the "end-of-sentence, end-of-line" rule.
1264: * This is a stable roll-back point before the mandoc hackathon in Rostock!
1265:
1266: Changes in version 1.9.24, released on May 9, 2010
1267:
1268: * Rolled back break-at-hyphen.
1269: * -DUGLY is now the default (no feature splits!).
1270: * Free-form text is not de-chunked any more: lines are passed
1271: whole-sale into the front-end, including whitespace.
1272: * Added mailing lists.
1273:
1274: Changes in version 1.9.23, released on April 7, 2010
1275:
1276: * mdocml has been linked to the OpenBSD build.
1277: * This version incorporates many small changes, mostly from patches
1278: by OpenBSD, allowing crufty manuals to slip by with warnings instead
1279: of erroring-out.
1280: * Some subtle semantic issues, such as punctuation scope, have also
1281: been fixed.
1282: * Lastly, some issues with -Thtml have been fixed, which prompted an
1283: update to the online manual pages style layout.
1284:
1285: Changes in version 1.9.22, released on March 31, 2010
1286:
1287: * Adjusted merge of the significant work by Ingo Schwarze
1288: in getting "Xo" blocks (block full implicit, e.g., "It"
1289: for non-columnar lists) to work properly. This isn't
1290: enabled by default: you must specify -DUGLY as a compiler
1291: flag (see the Makefile for details).
1292:
1293: Changes in version 1.9.20, released on March 30, 2010
1294:
1295: * More efforts to get roff instructions in man(7) documents under
1296: control. Note that roff instructions embedded in line-scoped,
1297: next-line macros (e.g. "B") are not supported.
1298: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
1299: are now correctly handled.
1300:
1301: Changes in version 1.9.18, released on March 27, 2010
1302:
1303: * Many fixes (largely pertaining to scope)
1304: and improvements (e.g., handling of apostrophe-control macros,
1305: which fixes the strange "BR" seen in some macro output)
1306: to handling roff instructions in man(7) documents.
1307:
1308: Changes in version 1.9.17, released on March 25, 2010
1309:
1310: * Accept perlpod(1) standard preamble.
1311: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
1312: roff macro blocks.
1313:
1314: Changes in version 1.9.16, released on March 22, 2010
1315:
1316: * Inspired by patches and bug reports by Ingo Schwarze,
1317: allowed man(7) to accept non-printing elements to be nested
1318: within next-line scopes, such as "br" within "B" or "TH",
1319: which is valid roff.
1320: * Longsoon architecture also noted and Makefile cleaned up.
1321:
1322: Changes in version 1.9.15, released on February 18, 2010
1323:
1324: * Moved to our new BSD.lv home.
1325: * XHTML is now an acceptable output mode for mandoc(1);
1326: * "Xr" made more compatible with groff;
1327: * "Vt" fixed when invoked in SYNOPSIS;
1328: * "\\" escape removed;
1329: * end-of-line white-space detected for all lines;
1330: * subtle bug fixed in list display for some modes;
1331: * compatibility layer checked in for compilation in diverse
1332: UNIX systems;
1333: * and column lengths handled correctly.
