mdocml – mdoc macro compiler

DESCRIPTION

mdocml is a suite of tools compiling -mdoc, the roff macro package of choice for BSD manual pages, and -man, the predominant historical package for UNIX manuals. The mission of mdocml is to deprecate groff, the GNU roff implementation, for displaying -mdoc pages whilst providing token support for -man.

Why? groff amounts to over 5 MB of source code, most of which is C++ and all of which is GPL. It runs slowly, produces uncertain output, and varies in operation from system to system. mdocml strives to fix this (respectively small, C, ISC-licensed, fast and regular).

The core of mdocml is composed of the libmdoc, libman, and libroff validating compiler libraries. All are simple, fast libraries operating on memory buffers, so they may be used for a variety of front-ends (terminal-based, CGI and so on). The front-end is mandoc, which formats manuals for display.

The mdocml suite is a BSD.lv Project member.

SOURCES

Sources correctly build and install on DragonFly BSD, FreeBSD, OpenBSD, NetBSD, GNU/Linux, and many other operating systems, tested variously on i386, AMD64, alpha, and others. The most current version is @VERSION@, dated @VDATE@. A full ChangeLog (txt) is written with each release.

NEWS

xx-05-2010	Release consisting of the results from the m2k10 hackathon and up-merge from OpenBSD. This requires a significant note of thanks to Ingo Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work, and again to Joerg for hosting m2k10. Highlights (mostly cribbed from Ingo's m2k10 report) follow in no particular order: a libroff preprocessor in front of libmdoc and libman stripping out roff instructions; end-of-sentence (EOS) detection in free-form and macro lines; correct handling of tab-separated columnar lists in -mdoc; improved main calling routines to optionally use mmap() for better performance; cleaned up exiting when invoked as -Tlint or over multiple files with -fign-errors; error and warning message handling re-written to be unified for libroff, libmdoc, and libman; handling of badly-nested explicit-scoped macros; improved free-form text parsing in libman and libmdoc; significant GNU troff compatibility improvements in -Tascii, largely in terms of spacing; a regression framework for making sure the many fragilities of GNU troff aren't trampled in subsequent work; support for -Tascii breaking at hyphens encountered in free-form text; and many more minor fixes and improvements (no really, consult cvsweb and see for yourself!). Version: 1.10.0.
13-05-2010	Fixed handling of \*(Ba escape. Backed out -fno-ign-chars (pointless complexity). Fixed erroneous breaking of literal lines. Fixed SYNOPSIS breaking lines before non-initial macros. Changed default section ordering. Most importantly, the framework for end-of-sentence double-spacing is in place, now implemented for the end-of-sentence, end-of-line rule. This is a stable roll-back point before the mandoc hackathon in Rostock! Version: 1.9.25.
09-05-2010	Rolled back break-at-hyphen. -DUGLY is now the default (no feature splits!). Free-form text is not de-chunked any more: lines are passed whole-sale into the front-end, including whitespace. Added mailing lists. Lastly, mdocml is the focus of two Google Summer of Code projects this year: mandoc -Tps (NetBSD) and BSD-licensed Text-Processing Tools (FreeBSD). Version: 1.9.24.
07-04-2010	mdocml has been linked to the OpenBSD build. This version incorporates many small changes, mostly from patches by OpenBSD, allowing crufty manuals to slip by with warnings instead of erroring-out. Some subtle semantic issues, such as punctuation scope, have also been fixed. Lastly, some issues with -Thtml have been fixed, which prompted an update to the online manual pages style layout. Version: 1.9.23.
