Hello,

I'm pleased to announce mdocml 1.12.1, now at http://mdocml.bsd.lv/.

Among many, many improvements, this release has an improved mandocdb(8) 
and the constellation of UNIX manpage tools (apropos(1), whatis(1), 
man.cgi(7)).  I snuck a controversial bit into apropos(1) and whatis(1): 
if the terminal is a TTY, one can choose output from a list and see the 
manpage for it.  These tools will need a lot of work -- the legacy tools 
have seen many years of polish and development -- but it's a start.

For a full list of changes, see the attached ChangeLog. An abbreviated
list of changes is on the NEWS section of the web-site.

As usual, sources are at http://mdocml.bsd.lv/snapshots/mdocml.tar.gz.

Thanks,

Kristaps

2012-03-23 22:18  kristaps

	* apropos.c: Forgot chdir(2) into volume path.

2012-03-23 22:07  kristaps

	* apropos.c, index.sgml: Small tweaks for release.

2012-03-23 21:54  kristaps

	* Makefile, index.sgml, whatis.1: Get ready for a version.

2012-03-23 21:46  kristaps

	* apropos.1, apropos.c, apropos_db.c, apropos_db.h, cgi.c: Be
	  insane.  Make apropos(1) subsume man(1).

2012-03-23 20:31  kristaps

	* apropos.c, apropos_db.c, apropos_db.h, cgi.c: Simplify by not
	  pre-filtering the result vector for satisfied matches: we can do
	  this in the frontend.

2012-03-23 20:30  kristaps

	* man.cgi.7: Whitespace fix.

2012-03-23 05:03  kristaps

	* cgi.c: Knock out useless & confusing whatis mode.

2012-03-23 02:52  kristaps

	* mandocdb.c: Improve mandocdb's ability to handle NAME sections by
	  sucking the entire shebang into a buffer and parsing it that way.
	  This improves on many cruddy -man manuals in the wild.

2012-03-23 01:50  kristaps

	* mdoc_argv.c, mdoc_validate.c: Make the `-width' field to `Bl' not
	  puke if it doesn't have an argument.	This makes mandoc work
	  much, much nicer with Mac OSX manpages.

2012-03-23 01:45  kristaps

	* mandocdb.c: Clean up code a bit by pushing warnings into WARNING
	  macro.

2012-03-23 01:07  kristaps

	* apropos_db.c, mandocdb.c: Merge some/most of schwarze@'s OpenBSD
	  changes into mandoc: many more warnings about grokking manpages
	  in their respective directories.  DO NOT, however, import his
	  temporary-file routines (I don't plan on staying with a
	  recno/btree split) nor the realpath() routines, which destroy
	  relative path-ness.

	  Also pull in the lorder bits.

	  There are some changes I started to make then stopped relating to
	  reporting errors in the correct directories.	I'll clean this up
	  in subsequent commits.

	  This puts us more or less on parity with OpenBSD.

2012-03-23 01:05  kristaps

	* Makefile: Remove some Mac OS crap in the Makefile.

2012-03-22 22:53  kristaps

	* Makefile: Don't run superfluous mkdir when installing.

2012-03-22 22:52  kristaps

	* apropos.c, mandocdb.h: Revert to mandocdb.{index,db} for database
	  files.

2012-03-04 18:53  schwarze

	* TODO: two reminders

2012-02-26 16:47  schwarze

	* st.in: Correct the expansion of -xbd5; from Philip Guenther
	  <guenther at openbsd dot org>.  OK Werner Lemberg <wl at gnu dot
	  org>.

2012-02-16 15:51  joerg

	* mandoc.h, read.c: Add mparse_readmem, which allows application to
	  run the parser directly from memory, e.g. after de-compressing a
	  document.

2012-02-05 11:46  joerg

	* read.c: Don't silently skip non-ASCII characters, but replace
	  them with ``?''.  This is less likely to break the syntax of
	  macros.

2012-01-28 18:46  joerg

	* lib.in: Add libquota

2012-01-28 09:04  joerg

	* lib.in: Add libisns, libppath and libsaslc from NetBSD. Fix
	  formatting of librt.

2012-01-28 09:02  joerg

	* arch.in: Add x86 pseudo architecure

2012-01-22 20:41  joerg

	* TODO: Add entry about the .TP / .RS crash before I forget about
	  it again.

2012-01-13 10:27  joerg

	* mandoc.3: Reflect reality, mandoc_escape does not skip the "\"
	  itself, but expects the caller to have done that.

2012-01-04 19:43  schwarze

	* mdoc_macro.c: Fix previous such that all .It HEADs are unparsed,
	  not just the first one in each -diag list.  While here, drop the
	  needless if-statement and choose a more precise wording for the
	  comment.  ok kristaps@

2012-01-03 10:17  kristaps

	* catman.c: Local variable initialisation.

2012-01-03 10:16  kristaps

	* man.7, man.c, man.h, man_html.c, man_macro.c, man_term.c,
	  man_validate.c: Add support for `OP', one of the extended man
	  macros.  This also requires some man(7) changes to accomodate for
	  the an-ext compatibility.

2012-01-03 05:18  kristaps

	* mdoc.7, st.in: Accommodate for ISO C11.  groff applied the same
	  `St' argument on 03/01/2012.	From a tweaked patch (isoC-11 ->
	  isoC-2011) by Ulrich Sporlein: thanks!

2012-01-02 10:48  kristaps

	* TODO, mdoc_macro.c: `-diag' lists aren't parsed, unlike other
	  list types.  This fixes a TODO entry raised by deraadt@.

2011-12-31 13:48  kristaps

	* man-cgi.css: Fix ID vs. CLASS for man.cgi CSS selector on results
	  table and vertically align.

2011-12-31 13:47  kristaps

	* apropos.c, mandocdb.c: When parsing catpages, read from the first
	  section (NAME, we hope) until the next section.  Also, remove the
	  limit of 72 characters and enforce this, instead in the apropos
	  frontend.

2011-12-27 19:32  schwarze

	* mandocdb.c: Do not skip manuals shared across architectures when
	  building databases.

2011-12-25 16:00  schwarze

	* mandocdb.8: Update the whatis.db database format.  While here,
	  reference apropos(1) from the description, inspired by the
	  makewhatis(8) manual.

2011-12-25 14:35  kristaps

	* apropos.1, catman.8, demandoc.1, mandoc.1, preconv.1, whatis.1:
	  State default usage before listing arguments of a utility.
	  Inspired by a patch to mandocdb.8 by schwarze@ some time ago.  Ok
	  jmc@.

2011-12-25 14:31  kristaps

	* mandocdb.c: First memory leak in mandocdb.c freeing "struct of".
	  Also properly const-ify several strings.

2011-12-25 12:49  kristaps

	* Makefile, catman.c, cgi.c: Continue changing mandoc.{index,db}
	  into whatis.{index,db}.  Use mandocdb.h to do so.

2011-12-25 11:53  schwarze

	* apropos.1, mandocdb.8, mandocdb.c, mandocdb.h, whatis.1: Use the
	  traditional name "whatis.db" for the mandocdb(8) databases.
	  Requested by deraadt@, ok kristaps@.

2011-12-25 09:58  schwarze

	* apropos_db.c, mandocdb.c, mandocdb.h: For binary compatability of
	  the databases across architectures, use pointers to arrays, not
	  pointers to structs.	It is now possible to create databases on
	  sparc64 and use them on i386 and vice versa.	Kristaps@ can't
	  think of anything else that might be required, either.  Put this
	  in now such that we can move on.

2011-12-25 08:08  schwarze

	* mandocdb.8, mandocdb.c: Implement test mode (makewhatis -t),
	  required for pkg_create(8).  Always do all consistency checks;
	  when any one fails, decide whether to print a message, or skip
	  the file, or both, or none.

	  While here, do some cleanup as well: * Bail out on conflicting
	  options.  * Do not crash with -a if there are plain files in the
	  root dir.  * Collect some related variables into structs.

	  Feedback and OK kristaps@.

2011-12-24 17:37  kristaps

	* apropos.1, catman.8, manpath.c, whatis.1: Support leading,
	  trailing and double colons in MANPATH to prepend, append or
	  insert the man.conf(5) default path; compatible with GNU
	  manpath(1), implementation by kristaps@, heavily tweaked by
	  schwarze@.

	  Updates to MANPATH documentation applied to whatis.1, apropos.1,
	  and catman.8 also.

2011-12-20 16:41  schwarze

	* apropos_db.c, mandocdb.c: Do not cast void pointers to pointers
	  requiring alignment.	This makes mandocdb(8)/apropos(1) work on
	  strict alignment architectures.  Basic way to fix this confirmed
	  by deraadt@ and kettenis@, thanks.  ok kristaps@

	  This now works on both sparc64 and i386, but note that the binary
	  database format is still machine-dependent.

2011-12-18 13:51  kristaps

	* catman.8, catman.c: Give catman(8) the -C flag (like apropos and
	  friends) and merge in some documentation from apropos(1) to be
	  consistent.

2011-12-18 09:27  kristaps

	* compat_fgetln.c, compat_getsubopt.c, compat_strlcat.c,
	  compat_strlcpy.c: Make compat files actually use compat.h.
	  Ooops.

2011-12-16 15:06  kristaps

	* apropos_db.c, cgi.c: Two lint fixes.

2011-12-16 15:05  kristaps

	* cgi.c: Fix assertion found when plugging legacy man.cgi query
	  string into my man.cgi.

2011-12-16 14:18  kristaps

	* man-cgi.css: Edge in a little style.	Why not.

2011-12-16 13:37  kristaps

	* cgi.c: When routing to a "result" page in the cgi, remember our
	  input parameters and repeat them in the search bar.  This is
	  handy.  While here, make the QUERY_STRING parser a bit simpler.

2011-12-16 10:05  kristaps

	* man-cgi.css: Have results table inherit the small font.

2011-12-16 07:07  kristaps

	* apropos_db.c: Make sure that "any" is UINT64_MAX, not just
	  INT_MAX, else "any" won't cover all types.  Found after some
	  database trawling.

2011-12-16 07:06  kristaps

	* apropos_db.c, apropos_db.h, catman.c, cgi.c, mandocdb.8,
	  mandocdb.c: Make the stored "cat"/"mdoc"/"man" strings just be
	  c/d/a single-character bytes.  This cuts down a little in index
	  size and allows for cleaner extraction of information.

2011-12-16 03:04  kristaps

	* catman.c, cgi.c, mandocdb.8, mandocdb.c: Make paths in the
	  mandocdb(8) index relative to the databases' path prefix.  This
	  means that an index in, say, /usr/share/man will point to
	  man1/foo.1 instead of /usr/share/man/man1/foo.1.  Not only does
	  this save a lot of space, it also allows manual trees to be moved
	  around without any side effects to the mandocdb(8) databases.

2011-12-15 07:44  kristaps

	* man-cgi.css: Don't make man.cgi default font-size dictate manual
	  style.

2011-12-15 07:18  kristaps

	* cgi.c, example.style.css, man-cgi.css: Further tweaks for output
	  consistency.

2011-12-15 07:07  kristaps

	* man.cgi.7: Update man.cgi.7 with new CSS files.

2011-12-15 07:05  kristaps

	* Makefile, cgi.c, example.style.css, man-cgi.css, man.cgi.css:
	  Some presentation polish in man.cgi:

	   - include search bar above result page (I relent: it's annoying
	  to
	     follow three links then press back three times to get a search
	  page);
	   - make man.cgi.css into man-cgi.css so Apache isn't confused by
	  two
	     handlers (css, cgi);
	   - finally consolidate example.style.css to be under the
	  div.mandoc css
	     selector;
	   - put catman pages under div.catman;
	   - put search bar under div#mancgi;
	   - reflect this properly in the bundled CSS files.

2011-12-14 18:17  kristaps

	* index.sgml: Note that archives are being hosted at gmane.

2011-12-14 08:36  kristaps

	* cgi.c, man.cgi.7: Unbreak man.cgi's css directories when CSS_DIR
	  isn't specified.

2011-12-13 16:09  kristaps

	* manpath.c: Remove stray warnx() left in the manpath.c code.

2011-12-13 15:56  kristaps

	* manpath.c, manpath.h: Have manpath.c properly use manpath(1),
	  that is, using -C and -m and so on.  This also cleans up the code
	  a little bit.  While here, make some functions static that are
	  only used within manpath.c.

2011-12-13 06:26  kristaps

	* Makefile, compat_fgetln.c, config.h.post, config.h.pre,
	  test-fgetln.c: Compatibility support fgetln() on Linux.  This
	  uses the BSD-licensed implementation from NetBSD tnftpd, Christos
	  Zoulas (copyright message retained in the compat_fgetln.c file).
	  Patch verified by schwarze@.	He notes that you'll need -pthread
	  for -static binaries (due to libdb), so I've noted that -static
	  should really only be used for BSD UNIX.

	  While here, add some forgotten goop to the Makefile, building and
	  cleaning extra manpages.

2011-12-11 21:00  schwarze

	* apropos.1, apropos.c, catman.c, cgi.c, mandocdb.8, mandocdb.c,
	  manpath.c, manpath.h, whatis.1: implement -C (alternative config
	  file) for apropos(1) and mandocdb(8), including various tweaks to
	  the whatis(8) manual; ok kristaps@

2011-12-10 19:38  schwarze

	* roff.7: Explain where .so paths are rooted, and why, and
	  discourage its use; feedback and ok jmc@, suggested by and ok
	  kristaps@.

2011-12-10 19:24  kristaps

	* man.cgi.7: Ugh, environmental variables are Ev, not Er.  Fix
	  typos.

2011-12-10 19:23  kristaps

	* man.cgi.7: Note CSS_DIR in man.cgi.7.

2011-12-10 19:22  kristaps

	* cgi.c: When 303'ing a search directly to a page, remember to
	  specify its manroot.	Also allow for a CSS_DIR to specify
	  alternate CSS locations.  Finally, some clutter as I assume that
	  "css" and "progname" are already HTML-safe.

2011-12-10 18:44  kristaps

	* index.sgml, man.cgi.7: Begin working on release notes.  Also
	  whitespace-fix man.cgi.7.

2011-12-10 18:31  kristaps

	* man.cgi.7: Update man.cgi.7 to note compatibility and running
	  with multiple roots.

2011-12-10 18:09  kristaps

	* cgi.c: Slip in a fix to allow for empty cache directories.

2011-12-10 18:04  kristaps

	* cgi.c: Finishing touches on multi-manroot man.cgi.  If more than
	  one root is specified, write them out using a SELECT box.  Else
	  write nothing (the manroot will still be checked if it's
	  specified).

2011-12-10 17:45  kristaps

	* cgi.c: Switch on "manpath=" handling, which I call the "manroot"
	  (as "manpath" is reserved for paths within a manroot).  This
	  functionality is bare-bones: right now, the default manroot is
	  the first one scanned from the cache directory.  At some point
	  this will be sexy and smooth, but it's easy to upgrade
	  functionality by modifying pathgen() and so forth.  If a manroot
	  isn't parsed from the "manpath=", results are always empty.

2011-12-10 17:20  kristaps

	* cgi.c: Encode "manroot" into file URL and parse it properly.
	  Right now this just uses the first manroot by default.

2011-12-10 17:01  schwarze

	* mandocdb.c: Avoid leaking index records: Before allocating a
	  record for a file, first make sure we actually want to use the
	  file.

2011-12-10 16:51  kristaps

	* cgi.c: Big upgrade and polish for cgi.c.

	  - Deprecate kvals (key/value pairs for QUERY_STRING values).
	  Since there's only one place that uses this, kval_parse (now
	  http_parse()) dumps directly into struct query, which is more
	  high-level.

	  - Put query values directly into struct req.

	  - The biggest difference is dynamic support for multiple
	  "manroots".  A "manroot" is a path with an "etc/catman.conf"
	  file.  When the cgi starts, it (prefix) recurses through its
	  CACHE_DIR searching for "etc" directories.  When one's found, it
	  sees if a catman.conf file exists.  This is marked as a manroot
	  and appended to a list.  The name of a manroot is the path
	  without slashes (e.g., OpenBSD/4.9 -> "OpenBSD 4.9").

	  Right now "manroot" isn't enabled.  The first manroot is chosen
	  as the real one.  I'll add the interface to it in the next
	  checkins, but it'll be quite simple.

2011-12-10 16:46  kristaps

	* apropos_db.c: Plug a memory leak in single_search().

2011-12-10 11:53  schwarze

	* mandocdb.c: Fix selection of arch-specific manuals: (1) Correctly
	  compare cat vs. man paths.  (2) Compare arch (and section) names
	  case-insensitively.  Problem noticed by kristaps@.

2011-12-10 06:00  kristaps

	* Makefile: Adding some missing "install" bits to Makefile.

2011-12-10 05:59  kristaps

	* cgi.c: FreeBSD's man.cgi uses a "default" value for no arch.

2011-12-09 19:06  kristaps

	* cgi.c: Add some periods (just to see if mlmmj is working
	  again...).

2011-12-09 18:18  kristaps

	* cgi.c: Forgot to make whatis the default during abstraction.	Do
	  it again.

2011-12-09 06:29  kristaps

	* cgi.c: Abstract query extraction code.  Perform some readability
	  fixes while here.

2011-12-09 06:18  kristaps

	* apropos_db.c: When specifying an architecture to
	  whatis(1)/apropos(1)/man.cgi(7), do a comparison only if the
	  manual specifies an architecture, otherwise let it through.
	  Looked over by schwarze@.  This brings us much more in line with
	  OpenBSD's behaviour.

2011-12-09 06:16  schwarze

	* mandocdb.c: Tweak pformatted(): * If the first section is empty,
	  use the file name as .Nd.  * No need to check (len > 0) after
	  successful fgetln(3).  * Improve some comments and strip trailing
	  whitespace.  ok kristaps@

2011-12-08 20:21  kristaps

	* mandocdb.c: Considerably tidy mandocdb(8) catman descriptions by
	  skipping to the first hyphen-space combo, not the last hyphen as
	  done previously.

2011-12-08 19:49  kristaps

	* mandocdb.c: Strip backspace encoding from preformatted manuals.
	  This cleans up a lot of catpage entries in the mandoc databases.

2011-12-08 17:47  kristaps

	* cgi.c: If no man.cgi `whatis' results are found, offer a quick
	  link to the apropos query mode.

2011-12-08 13:39  kristaps

	* cgi.c: Fix stupid typo: strlcpy() instead of strlcat().

2011-12-08 04:19  kristaps

	* mandocdb.c: Clean up grok of preformatted manual description.
	  (1) put fclose() at the end, as line isn't valid afterward (see

	* cgi.c: Accept old-school man.cgi parameters like "sektion" and
	  "query".  This still needs work because specifying an arch with
	  "arch=i386" will return results that don't have an arch
	  specified.  I think this is weird, but it will need to be
	  supported if we want backwards compatibility.

	  While here, fix the cat.css location (erroneously put in the

	  dodgy.  This will need some more work (links, etc.) but does a
	  decent job thusfar.

	  Note: I think it's better style NOT to use <pre>, and instead
	  have each line employ <BR> afterward.  This allows browsers to
	  break the lines if necessary.  This can be changed trivially
	  (replacing the newline and pre tags with the <BR> and new tag).

	* mdoc_validate.c: When processing .Sh HEAD, as soon as we know
	  which section this is, fix up the section attributes of the HEAD,
	  it's parent BLOCK, and all its (text) children.  This is required
	  because the section attributes get set when each node is
	  allocated, i.e. before processing the content of the node itself.
	  Thus, the listed nodes got the section attribute of the
	  preceding section.  No need to fix up the BODY, all is fine there
	  already.  Found while implementing TYPE_Sh for mandocdb(8).  OK

	  why shouldn't we?

2011-11-24 07:43  kristaps

	* Makefile, man.cgi.7: Make a small manual for how to run man.cgi.
	  This exists almost entirely to document that /tmp must exist in a
	  jailed Apache directory for dbopen() not to fail.  This was a
	  massive headache to track down.

2011-11-24 07:27  kristaps

	* cgi.c: Let man.cgi run in two modes:

	   (1) Insecure.  This means that we're operating over the full
	  file-system
	       with access to mandoc(1).  In this mode, mandocdb entries
	  are formatted
	       on-the-fly.  The $INSECURE environment variable must be
	  passed to
	       man.cgi for this mode to work.

	   (2) Secure.	Manuals are assumed to be pre-formatted in a cache
	  directory,
	       which may be set with $CACHE_DIR but default to
	  /cache/man.cgi.
	       This mode works with manup(8), which updates the cached
	  pages from
	       outside of the jail.  man.cgi simply locates the manual file
	  and
	       outputs it to stdout.

2011-11-24 07:22  kristaps

	* manup.c: Have manup(8) put relative paths in its output man.conf.
	  This lets us have arbitrarily-located cache directories for
	  man.cgi.

2011-11-24 05:44  kristaps

	* manpath.c, manpath.h: Allow man.conf file to be assignable.

2011-11-24 05:43  kristaps

	* manpath.c, manpath.h: Export the manpath_manconf() function,
	  slightly reorderng manpath.c while doing so.	This will be used
	  by a jailed man.cgi, as the cache built by manup(8) creates a
	  man.conf for it to use.

2011-11-24 05:33  kristaps

	* Makefile, manup.8, manup.c: Add manup(8).  This runs through
	  mandocdb(8) databases (in the same way that apropos(1) does so)
	  and updates an HTML fragment cache for use by man.cgi.  Right now
	  man.cgi is "online" in that it requires mandoc(1) in its path,
	  but this doesn't work for, say, OpenBSD's apache chroot(1).  This
	  allows a cache to be maintained.

	  you smash this into a cgi-bin directory, it will Just Work for

	  your file-system, hence "non-jailed").  The notion of a jailed

	* apropos_db.c, apropos_db.h: Let apropos_db.h export the volume of
	  manpages for a parsed record.  This is necessary since an array
	  of records can have duplicate record numbers in different
	  mandoc.index files.  The volume [right now] is just the index of
	  the parsed mandoc.index in the manpaths.  This is sensible
	  because the order of the manpath is significant (it's the order
	  of duplicate-named manuals displayed by man(1)) and is thus not
	  likely to change.

	* mandocdb.8, mandocdb.c: Have mandocdb(8) take advantage of

	* apropos.1, apropos.c, apropos_db.c: Clarify some behaviour,
	  bringing schwarze@'s patch and mine closer together (although I
	  still don't have -M, which is a big piece).

	  First, the default search path is the cwd.  This will change to
	  use -M once I look over that code.

	  If MANPATH is specified, this replaces the cwd.

	  Both of these are augmented by -m.

	  If paths don't exist or don't have databases, they're silently
	  ignored.  This makes perfect sense: you may be given a superset
	  of possible paths.  The corner case of no paths (where, say,
	  MANPATH consists of bogus paths or the cwd is unreadable) simply
	  means that no paths are searched.

	  follow:

	   (1) don't support -M yet;
	   (2) fall back to cwd if no prior manpath has been specified;
	   (3) resolve manpages using realpath() to prevent consecutive
	  chdir()'s

	* apropos.c, apropos_db.c, apropos_db.h: Have exprcomp() accept a
	  string instead of an array-pointer.  Also, collapse the arguments
	  in apropos(1) into a single string passed to exprcomp().  Ok
	  schwarze@.

2011-11-13 10:33  schwarze

	* man_term.c: Make the man(7) page footer the same as in groff.

2011-11-13 09:50  schwarze

	* mandoc.1: typo: overful -> overfull; thanks to jmc@

2011-11-13 08:15  schwarze

	* man_term.c, mandoc.1, mdoc_term.c, term.h, term_ascii.c: Make the
	  default left text margin configurable from the command line, just
	  like the default right margin already is.  This may be useful for
	  people with expensive screen real estate.  Besides, it helps
	  automated man(7) to mdoc(7) output comparisons to validate -Tman
	  output.  ok kristaps@ on an earlier version

2011-11-13 06:10  schwarze

	* apropos.c, apropos_db.c, apropos_db.h: Rewrite the expression
	  parser for a more concise syntax:

	   apropos [search_type[,...]=]substring
	   apropos search_type[,...][,i]~regex

	  ... and expression evaluation must take the search type into
	  account.

	  This allows to: * drop the global -I option and * drop the enum
	  match, just using a boolean int.

	  "go ahead" kristaps@

	* Makefile, apropos_db.c, apropos_db.h, cgi.c, mandocdb.c,
	  mandocdb.h: Inventing new keywords for mostly the same thing when
	  a well-established set of keywords already exists is a bad idea,
	  so reuse the mdoc(7) macro names as apropos(1) search types.
	  This is a gain in brevity as well.  Some time ago, kristaps@
	  agreed in principle.

	  The search type bit field constants are used by both mandocdb(8)
	  and apropos(1) and should better stay in sync, so give them their
	  own header file.

2011-11-13 05:12  schwarze

	* Makefile, apropos.c, apropos.h, apropos_db.c, apropos_db.h,
	  cgi.c, db.c: Less misleading file names; ok kristaps@.

2011-11-13 05:02  schwarze

	* TODO: another detail to implement; long live the tricky
	  exceptions!

2011-11-12 19:53  schwarze

	* mandocdb.c: Fix two crashes that occur when walking very large
	  (i.e. real-world) trees: 1) Avoid excessive, needless recursion,
	  lest you overflow the stack; 2) Close all dir file descriptors,
	  lest you run out of descriptors.  ok kristaps@

2011-11-09 18:31  kristaps

	* db.c: Use proper infix expressions and provide a default.  (Exact
	  match.)

2011-11-09 17:05  kristaps

	* apropos.c, apropos.h, cgi.c, db.c: Make apropos's lookup use a
	  find(1)-like expression.  I'll write more on this when it
	  completes; this is to keep it in-tree.

	  Right now this uses prefix notation.	Ignore it.  I'll make this
	  into infix notation real soon.

	  The goal of this (exprcomp and exprexec) is to have arbitrary
	  logical expressions.

2011-11-09 05:53  kristaps

	* apropos.1, apropos.c: Change getopt() to be more like schwarze@'s
	  suggestions.

2011-11-08 20:24  kristaps

	* Makefile, apropos.c, apropos.h, cgi.c, db.c: Split apropos.c into
	  db.c and apropos.h with simpler code (re-written, but inspired by
	  apropos.c and mandoc-tools' mandoc-cgi.c).  This uses UTF-8 right
	  now for its re-writing, but will soon accomodate for the regular
	  suspects (this is a rather simple matter).

	  I also introduce man.cgi (cgi.c), which is a standalone CGI that
	  replaces mandoc-tools' mandoc.cgi.  Right now it's just a
	  framework.

2011-11-07 19:15  kristaps

	* chars.c, mandoc.3, mandoc.h: Const-ify some mchars arguments.  I
	  think these are non-const for historical dumbness on my part.

2011-11-06 20:24  schwarze

	* TODO, libman.h, man.c, man_macro.c, man_validate.c, mandoc.h,
	  read.c: When the HEAD scope of .TP is broken by another block
	  macro, do not abort with a FATAL error, but report a report a
	  WARNING, remove the broken .TP from the syntax tree, and prod on.
	  Reported repeatedly by ports people, at least by brad@ and
	  jeremy@.  Also fixes rendition(4) in Xenocara.  ok kristaps@

2011-11-06 09:43  kristaps

	* mandoc.c, roff.7: Accomodate for \f(Cx formatting.  Noted by
	  Andreas Vogele, thanks!

2011-11-03 16:48  schwarze

	* man_validate.c: When .TH sets no data, leave the date field in
	  the page footer blank, do not use the current date.  This removes
	  a gratuitous output difference with respect to groff.  ok
	  kristaps@

2011-11-03 16:36  schwarze

	* mdoc_term.c, mdoc_html.c: Correct .Eo spacing: no space between
	  the delimiters and the enclosed text.  The mdoc_html.c part was
	  added by kristaps; ok kristaps@.

2011-11-01 10:59  schwarze

	* mdoc.7: Clean up the description of .Dt: - Volume and arch are
	  both optional and not alternatives.  - Zap verbiage about what's
	  obvious from the synopsis.  - For fixed argument strings, use
	  .Cm, not .Ar.  Using lots of input from jmc@.

	  Also, state that the list of valid architectures varies by OS.
	  If a downstream distribution wants to provide a specific list,
	  maintaining a local patch is the way to go.

2011-10-24 17:47  schwarze

	* mdoc_man.c: Implement missing enclosures (Ao Do Qo Qq So Bro Brq)
	  and enclosure-like in-line macros (Ad Cd Dv Er Ev Li Ms Tn).	The
	  .No macro works without explicit implementation.

	  ok kristaps@

2011-10-24 17:41  schwarze

	* roff.c: Handle infinite recursion the same way as groff: When
	  string expansion exceeds the recursion limit, drop the whole
	  input line, instead of leaving just the string unexpanded.

	  ok kristaps@

2011-10-24 16:30  schwarze

	* mandoc.c: Handle \N numbered character escapes the same way as
	  groff: If \N is followed by a digit, ignore \N and the digit.  If
	  \N is followed by a non-digit, the next non-digit ends the
	  character number; the two delimiters need not match.	Kristaps
	  calls that "gross, but not our fault".

	  For now, i'm fixing \N only.	Other escapes taking numeric
	  arguments may or may not need similar handling, but \N is by far
	  the most important for practical purposes.

	  ok kristaps@

2011-10-20 16:27  schwarze

	* mdoc_man.c: Implement the missing text production macros (Bsx Bx
	  Dx Fx Nx Ox Ux Bt Ud).  Some macros work without explicit
	  implementation (At Db Os St).  ok kristaps@

2011-10-18 09:25  kristaps

	* mandoc.3: Fix mandoc_escape() function argument names.  From a
	  fix by Abhinav Upadhyay, thanks!

2011-10-16 12:25  schwarze

	* arch.in, lib.in: Sync to groff, and add tier I and II NetBSD
	  architectures.  ok kristaps@

2011-10-16 08:20  schwarze

	* man_validate.c, mdoc_html.c, mdoc_macro.c, mdoc_term.c,
	  mdoc_validate.c, term_ps.c: Remove a bunch of useless
	  assignments, and assert that print_bvspace cannot be called on
	  NULL pointers.  No change in behaviour, none of these were bugs,
	  but the code becomes easier to understand.  Based on a clang
	  report posted by joerg@; ok kristaps@.

2011-10-09 18:10  schwarze

	* man_html.c, mdoc_html.c: Always print <table> column widths in
	  -T[x]html; if desired, they can be overridden in the CSS file.
	  Suggested by kristaps@, and i always like to simplify code.

2011-10-09 17:37  schwarze

	* mandoc.1: A bit more precision and nicer wording in the
	  descriptions of -Ofragment and -Tman; using input from jmc@ and
	  kristaps@.

2011-10-09 06:46  kristaps

	* apropos.c: Make apropos results-gathering able to error out and
	  clean up before making the utility exit non-zero.

2011-10-09 06:37  kristaps

	* apropos.c: Remove some unnecessary variables and note that
	  mchars_alloc never returns NULL.

2011-10-09 06:35  kristaps

	* apropos.c: Use a binary tree (for now, unbalanced) for deduping
	  the records in the results array.  This is much faster than the
	  previous method, a linear search, at a small cost.  Note that
	  array offsets are used instead of storing the res pointer because
	  we may realloc the results vector.

2011-10-09 04:56  kristaps

	* mandocdb.8: The documented flags in mandocdb (-u, -d) were
	  switched.  Fix this.
