* Implement the obsolete macros .En .Es .Fr .Ot for backward compatibility,Ingo Schwarze2014-07-021-13/+6
| | | | | since this is hardly more complicated than explicitly ignoring them as we did in the past. Of course, do not use them!
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-152/+129
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* Implement the roff(7) .ll (line length) request.Ingo Schwarze2014-03-301-0/+1
| | | | | Found by naddy@ in the textproc/enchant(1) port. Of course, do not use this in new manuals.
* Treat the line after .Cd as a single argument.Ingo Schwarze2014-01-211-1/+1
| | | | | This doesn't hurt normal manual display and makes the mandocdb(8) database more useful.
* Keep words after .Ic together in a single argument.Ingo Schwarze2014-01-201-1/+1
| | | | | This doesn't hurt normal manual display and makes the mandocdb(8) database more useful.
* Simplify: Remove an unused argument from the mandoc_eos() function.Ingo Schwarze2013-12-311-1/+1
| | | | No functional change.
* Do not trigger end-of-sentence spacing by trailing punctuationIngo Schwarze2013-12-311-19/+0
| | | | | | | | | | | | | | | | | | | | at the end of partial implicit macros. Prodded by jmc@. Actually, this is a revert of rev. 1.64 Fri May 14 14:09:13 2010 UTC by kristaps@, with this original commit message: "Block-implicit macros now up-propogate end-of-sentence spacing. NOTE: GROFF IS NOT SMART ENOUGH TO DO THIS." Please speak after me: Then why the hell should we? We already weakened this in rev. 1.93 Sun Jul 18 17:00:26 2010 UTC, but that weakening was insufficient. Let's take it out completely. Admittedly, there are two places in OpenBSD base where what Kristaps did make the output nicer, in calloc(3) and in fish(6). But both are atypical. There are 18 other places where this revert makes the output nicer, the typical case being: "Mail status is shown as ``No Mail.'' if there is no mail." You do *not* want the EOS spacing after ``No Mail.'' in that sentence.
* It turns out SYNOPSIS mode does not imply .Bk in general,Ingo Schwarze2013-12-241-2/+1
| | | | | | but only within .Nm blocks. Simplify the code accordingly. Triggered by research done by Franco Fichtner.
* When deciding whether two consecutive macros are on the same input line,Ingo Schwarze2013-12-241-0/+5
| | | | | | | | we have to compare the line where the first one *ends* (not where it begins) to the line where the second one starts. This fixes the bug that .Bk allowed output line breaks right after block macros spanning more than one input line, even when the next macro follows on the same line.
* There are three kinds of input lines: text lines, macros takingIngo Schwarze2013-10-211-98/+139
| | | | | | | | | | | | | | | positional arguments (like Dt Fn Xr) and macros taking text as arguments (like Nd Sh Em %T An). In the past, even the latter put each word of their arguments into its own MDOC_TEXT node; instead, concatenate arguments unless delimiters, keeps or spacing mode prevent that. Regarding mandoc(1), this is internal refactoring, no output change intended. Regarding mandocdb(8), this fixes yet another regression introduced when switching from DB to SQLite: The ability to search for strings crossing word boundaries was lost and is hereby restored. At the same time, database sizes and build times are both reduced by a bit more than 5% each.
* Block closing macros do not allocate a new node but finish an existingIngo Schwarze2013-09-151-0/+3
| | | | | | | | | | one, so they miss the clearing of MDOC_NEWLINE in mdoc.c, node_alloc(). Consequently, MDOC_NEWLINE must be cleared before processing the next macro on the same line. This fixes horizontal spacing for input lines beginning like .Oc Ns ... Issue found by Franco Fichtner <franco at lastsummer dot de> while working on DragonFly mandoc integration.
* Do not crash on stray .Ta macros found outside column lists.Ingo Schwarze2012-11-191-4/+10
| | | | Problem reported by jmc@, thanks.
* Fix four small whitespace issues related to trailing punctuationIngo Schwarze2012-11-181-1/+2
| | | | | | | | | reported by Nicolas Joly <njoly at pasteur dot fr>: - add EOS spacing after trailing punctuation after .Cd, .Fc, and .Lb - suppress spacing before trailing punctuation after .Fd Add the remaining issues from the same report to the TODO file.
* Cleanup naming of local variables to make the code easier on the eye:Ingo Schwarze2012-11-171-175/+180
| | | | | | | | Settle for "struct man *man", "struct mdoc *mdoc", "struct meta *meta" and avoid the confusing "*m" which was sometimes this, sometimes that. No functional change. ok kristaps@ some time ago
* Fix a crash triggered by .Bl -tag .It Xo .El .Sh found by florian@.Ingo Schwarze2012-11-161-1/+1
| | | | | | | | | | | | | | | * When allocating a body end marker, copy the pointer to the normalized block information from the body block, avoiding the risk of subsequent null pointer derefence. * When inserting the body end marker into the syntax tree, do not try to copy that pointer from the parent block, because not being a direkt child of the block it belongs to is the whole point of a body end marker. * Even non-callable blocks (like Bd and Bl) can break other blocks; when this happens, postpone closing them out in the usual way. Completed and tested at the OpenBSD impromptu Coimbra hackathon (c2k12). Thanks to Pedro Almeida and the Laborat'orio de Computa,c~ao Avan,cada da Universidade de Coimbra (http://www.uc.pt/lca) for their hospitality!
* Let a trailing .Ns macro take effectIngo Schwarze2012-07-181-1/+8
| | | | | | | | even on an input line containing a partial implicit macro. Fixes horizontal spacing in vi(1), ddb(4), and ppp(8). OpenBSD rev. 1.74.
* update Copyright years according to the CVS logs; no code changeIngo Schwarze2012-05-271-1/+1

* Fix previous such that all .It HEADs are unparsed,Ingo Schwarze2012-01-051-10/+8
| | | | | | | 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@

* Remove an OpenBSD-specific tweak regarding .Xr spacing and make itIngo Schwarze2011-12-031-16/+0
| | | | | | | compatible with groff-1.21. This tweak was originally added for compatibility with groff-1.15, which is no longer needed. ok jmc@ kristaps@
* Remove a bunch of useless assignments,Ingo Schwarze2011-10-161-4/+1
| | | | | | | 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@.
* forgotten Copyright bumps; no code changeIngo Schwarze2011-09-181-1/+1
| | | | found while syncing to OpenBSD
* Allow `Sx' and `Ss' to have child nodes. Fixes manuals in NetBSD.Kristaps Dzonsons2011-08-101-2/+2
| | | | | | Originally pointed out by joerg@ then again by Thomas Klausner by way of Nicolas Joy. Note: don't use these constructions as you can't link to the sections with `Sx'.
* No code change: fixing spelling errors. From a patch by uqs@. Thanks!Kristaps Dzonsons2011-04-301-4/+4

* Closing delimiters only suppress spacing when they follow something.Ingo Schwarze2011-04-251-1/+13
| | | | | Fixing a regression introduced in rev. 1.105. ok and prodding for comments kristaps@.
* Clean up parsing of delimiters in -mdoc. First, remove the "dowarn"Kristaps Dzonsons2011-04-191-3/+3
| | | | | | | | variable from mandoc_getarg() so that it prints the warning every time. Then, remove the warning from args_checkpunct(). This way, warnings are being posted at the correct time. This makes the flag argument to mdoc_zargs() superfluous, so make it be zero when it's invoked. Finally, move the args() flags into mdoc_argv.c and make them enums.
* libmdoc.h and libman.h were including mdoc.h and man.h, respectively.Kristaps Dzonsons2011-03-221-0/+1
| | | | | Don't have them do that (includes in header files = faugh), and have individual files directly include these files.
* Move mandoc_isdelim() back into libmdoc.h. This fixes an unreportedKristaps Dzonsons2011-03-221-24/+47
| | | | | | | | | error where (1) -man pages were punctuating delimiters (e.g., `.B a ;') and where (2) standalone punctuation in -mdoc or -man (e.g., ";" on its own line) would also be punctuated. This introduces a small amount of complexity of mdoc_{html,term}.c must manage their own spacing with running print_word() or print_text(). The check for delimiting now happens in mdoc_macro.c's dword().
* Consolidate messages. Have all parse-time messages (in libmdoc,Kristaps Dzonsons2011-03-201-7/+8
| | | | | | | | | libroff, etc., etc.) route into mandoc_msg() and mandoc_vmsg(), for the time being in libmandoc.h. This requires struct mparse to be passed into the allocation routines instead of mandocmsg and a void pointer. Then, move some of the functionality of the old mmsg() into read.c's mparse_mmsg() (check against wlevel and setting of file_status) and use main.c's mmsg() as simply a printing tool.
* Clean-up in libmdoc: fix last checks for mdoc_*msg return value, thenKristaps Dzonsons2011-03-171-10/+9
| | | | | make mdoc_vmsg not return an int. libmdoc is now completely clean of return-value checks from the message subsystem.
* Move mdoc_isdelim() into mandoc.h as mandoc_isdelim(). This allows theKristaps Dzonsons2011-03-171-7/+7
| | | | | | removal of manual delimiter checks in html.c and term.c. Finally, add the escaped period as a closing delimiter, removing a TODO to this effect.
* Have `Bx' accept two arguments, not just one, and join these argumentsKristaps Dzonsons2011-01-251-0/+2
| | | | with "xxBSD-yy"
* Incorporate same fix for -man post-validation deletion of nodes. ThisKristaps Dzonsons2011-01-121-2/+9
| | | | isn't known to cause any problems, but better safe than sorry.
* Add a "last child" member of struct mdoc_node.Kristaps Dzonsons2010-12-151-0/+3
| | | | | | | Remove `Pp' or `Lp' if it is the FIRST or LAST child of an `Sh' or `Sh' body. Make "skipping paragraph" be an error, not a warning, as information (an invoked macro) is ignored.
* Merge schwarze@'s relaxation of scope-breaking rules: allow implicitKristaps Dzonsons2010-12-061-21/+21
| | | | ending of scopes and drop stray scope-endings.
* mdoc_action.c is no more. Attic it and remove it from the Makefile.Kristaps Dzonsons2010-11-301-10/+2
| | | | | Remove references to MDOC_ACTED (it was only assertions) and the pre- and post-action functions.
* Move `Mt', `Ar', and `Li' handling from mdoc_action.c into mdoc_validate.c.Kristaps Dzonsons2010-11-291-1/+1
| | | | | | | | Clarify that `Mt' gets a default `~' (as per groff 1.20) and document it in mdoc.7. Made `Lk' be removed in mdoc_macro.c if it has no arguments. This fixes segfaults in mdoc_{term,html}.c that nobody's managed to raise yet.
* * need a space before .No even if it starts with a closing delimiterIngo Schwarze2010-10-011-2/+2
| | | | | | | * slightly simplify .Pf *_IGNDELIM code, and share part of it with .No * do not let opening delimiters fall out of the front of .Ns (from kristaps@) This fixes a few spacing issues in csh(1) and ksh(1). OK kristaps@
* If an explicit scope is still open at the end of an input file,Ingo Schwarze2010-09-261-8/+4
| | | | | | | | | | report an ERROR: We can still render the page by just closing the open scope, but it is likely that information will be missing or document structure mangled. Before, man(7) only reported a WARNING (which is dangerous because we cannot be sure rendering is correct) and mdoc(7) ran into FATAL (which is too drastic, there is no reason not to show what we have). "looks good" kristaps@
* Text ending in a full stop, exclamation mark or question markIngo Schwarze2010-07-181-2/+2
| | | | | | | | | | | | | | | | | | should not flag the end of a sentence if: 1) The punctuation is followed by closing delimiters and not preceded by alphanumeric characters, like in "There is no full stop (.) in this sentence" or 2) The punctuation is a child of a macro and not preceded by alphanumeric characters, like in "There is no full stop .Pq \&. in this sentence" "looks fine" to kristaps@; tested by jmc@ and sobrado@
* Assert my copyright, making it explicit that i'm granting the same licenseIngo Schwarze2010-07-041-1/+2

* In the mdoc(7) parser, inspect roff registers early such that all partsIngo Schwarze2010-07-011-1/+4
| | | | | | | | | | | | of the parser can use the resulting cues. In particular, this allows to use .nr nS to force SYNOPSIS-style .Nm indentation outside the SYNOPSIS as needed by ifconfig(8). To actually make this useable, .Pp must rewind .Nm, or the rest of the section would end up indented. Implement a quick hack for now, a generic solution can be designed later. ok kristaps@ and tested by sobrado@
* Correct handling of trailing punctuation in MDOC_DELIM blk_full HEADs.Ingo Schwarze2010-07-011-0/+3
| | | | | | | The bug was uncovered by SYNOPSIS .Nm as this happened to be the first block with this particular combination of properties. Found the hard way by kristaps@ in NetBSD gcc-contrib(1), fix by me.
* Improve .Nm indentation in the SYNOPSIS;Ingo Schwarze2010-07-011-10/+19
| | | | | | | kristaps@ will do the missing HTML part soon. "looks nicer" jmc@ "seems perfect to me" sobrado@ "slap it in" kristaps@

* Closing of full blocks (Bd Bf Bk Bl It Fo Nd Rs Sh Ss) may never beIngo Schwarze2010-06-301-3/+42
| | | | | | | | | | delayed: It must either succeed right away or fail outright. As noticed by Kristaps, neglecting to fail properly when required could make invalid input screw up the syntax tree and ultimately trigger assertions in other, unrelated parts of the program. This fix tested by and OK by kristaps@. While here, comment the rather tricky function rew_dohalt(). This function will probably need more tweaks later on.
* fix a typo in the function declaration;Ingo Schwarze2010-06-291-1/+1
| | | | | seems like gcc3 didn't catch it :-( thanks to thib@ and kristaps@ for reporting
* Considerably simplify block rewind rules; no functional change intended.Ingo Schwarze2010-06-291-206/+69
| | | | | | | | | | * Let rew_alt() always succeed, obsoleting tons of case statements. * Merge rew_dobreak() into rew_dohalt(). * Encode all rewinding cases uniformly in terms of "enum rew". Required because i'm too dumb to get SYNOPSIS .Nm rewinding right without cleaning this up first. "get it in" kristaps@
* Support for badly nested blocks, written around the time ofIngo Schwarze2010-06-291-72/+194
| | | | | | | | | | | | | | | | | | | | | | | | | the Rostock mandoc hackathon and tested and polished since, supporting constructs like: .Ao Bo Ac Bc (exp breaking exp) .Aq Bo eol Bc (imp breaking exp) .Ao Bq Ac eol (exp breaking imp) .Ao Bo So Bc Ac Sc (double break, inner before outer) .Ao Bo So Ac Bc Sc (double break, outer before inner) .Ao Bo Ac So Bc Sc (broken breaker) .Ao Bo So Bc Do Ac Sc Dc (broken double breaker) There are still two known issues which are tricky: 1) Breaking two identical explicit blocks (Ao Bo Bo Ac or Aq Bo Bo eol) fails outright, triggering a bogus syntax error. 2) Breaking a block by two identical explicit blocks (Ao Ao Bo Ac Ac Bc or Ao Ao Bq Ac Ac eol) still has a minor rendering error left: "<ao1 <ao2 [bo ac2> ac1> bc]>" should not have the final ">". We can fix these later in the tree, let's not grow this diff too large. "get it in" kristaps@
