* Do not issue the message "no blank before trailing delimiter" for .No.Ingo Schwarze2017-06-111-1/+0
| | | | | | | In practice, that message only matters inside .Bf, and even there, it can occasionally be a false positive. In all other cases, it usually is a false positive, so it is better to drop it outright. Suggested by jmc@.

* Macro argument quoting does not prevent recognition of punctuationIngo Schwarze2017-05-30115-134/+592
| | | | | | | | | | | and of called macros. This bug affects almost all macros, and fixing it simplifies the code. It is amazing that the bogus ARGS_QWORD feature got implemented in the first place, and then carrier along for more than eight years without anybody ever noticing that it was pointless. Reported by Leah Neukirchen <leah at vuxu dot org>, found on Void Linux.
* Move .sp to the roff modules. Enough infrastructure is in placeIngo Schwarze2017-05-051-1/+1

* Parser reorg:Ingo Schwarze2017-05-041-1/+1
| | | | | Generate the first node on the roff level: .br Fix some column numbers in diagnostic messages while here.
* Delete .Pp right before the first .Sh and right before any .Ss,Ingo Schwarze2017-04-2810-4/+114
| | | | and warn about it; mdoclint(1) does so, and it makes sense.

* In markdown, autolinks are dangerous. Different compilers disagreeIngo Schwarze2017-03-114-8/+8
| | | | | | | | | | | with respect to what constitutes a valid autolink, and if a compiler deems an autolink invalid, the input turns into an unintended and potentially harmful raw HTML tag. So, never write autolinks. Instead of <link>, write [link](link). Instead of <addr>, write [addr](mailto:addr). Issue pointed out by bentley@, who also agrees with the general direction of the change.
* Really commit some files that failed to get committed in this commit:Ingo Schwarze2017-03-0923-24/+5
| | | | | | | Now that markdown output is tested for almost everything, test all input files in -T markdown output mode by default and only mark those files with SKIP_MARKDOWN that are not to be tested. Much easier to read, and almost minus 40 lines of Makefile code.

* Using .Nd only makes sense in the NAME section.Ingo Schwarze2017-03-061-0/+2
| | | | | Warn if that macro occurs elsewhere. Triggered by a question from Dag-Erling Smoergrav <des @ FreeBSD>.

* Use typographic quotes rather than '"' for .Rs %T (no change for -TasciiIngo Schwarze2017-02-175-0/+64
| | | | | output, of course). Patch from bentley@ in November 2014. This can be committed now because groff merged Anthony's patch yesterday.
* Many people have been complaining for a long time that ``...'' looksIngo Schwarze2017-02-177-12/+11
| | | | | | | | | | | ugly in -Tascii output. For that reason, bentley@ submitted patches to render "..." instead to groff in November 2014 (yes, more than two years ago). Carsten Kunze yesterday merged them for the upcoming groff-1.22.4 release. Yay! Consequently, do the same in mandoc: Render \(Lq and \(Rq (which are used for .Do, .Dq, .Lb, and .St) as '"' in -Tascii output. All other output modes including -Tutf8 remain unchanged.
* Surprisingly, groff does not support scaling units in .Bl -columnIngo Schwarze2017-02-161-1/+1
| | | | | | column width specifiers, so stop supporting them, too. As a side effect, this fixes an assertion failure that tb@ found with afl(1), triggered by: .Bl -column -4n
* Fix block scoping error if an explicit block is broken by twoIngo Schwarze2017-02-163-10/+26
| | | | | | | | | implicit blocks (.Aq Bq Po .Pc) that left the outer breaker open and could in exceptional cases, like between .Bl and .It, cause tree corruption leading to NULL dereference. Found by tb@ with afl(1). While here, do not mark intermediate ENDBODY markers as broken.
* new regression tests for mdoc_macro.c revs. 1.211-1.215Ingo Schwarze2017-02-1113-12/+85

* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-08654-0/+10739
| | | | | Both kristaps@ and wiz@ repeated asked for this, literally for years.
* Move the regression suite to the attic.Ingo Schwarze2014-03-0339-722/+0
| | | | | | | It has not been used or maintained for several years, and we won't start using it now. Devlopment regression testing is done in OpenBSD, and there is no value in maintaining two regression suites in parallel.
* Properly handle -mdoc %A in all outputs. This has two-author entiresKristaps Dzonsons2010-09-043-0/+48
| | | | | | | separated by only "and" while two or more are with ", and" for the last author. Also remove relevant TODO and add regression tests.
* Cached `Bl -offset' into mdoc_bl. Removed erroneous "-offset defaultsKristaps Dzonsons2010-06-121-0/+15
| | | | | to 6n if no value is specified" and added regression tests for `Bl' testing against the empty -offset argument.
* Removed stipulation that an empty `Bd -offset' will default to 6n. NotKristaps Dzonsons2010-06-123-0/+66
| | | | | | | sure where this came about. Added regression tests to convince myself that this is so. Also consolidated COMPATIBILITY notes regarding `Bd'. Added COMPATIBILITY note to the effect that old groff pukes on `Bd -compact -ragged' (regression test will fail on old groff).
* Cache all of `Bd's resolved arguments into mdoc_bd, which is stashed inKristaps Dzonsons2010-06-121-0/+28
| | | | | | the "data" union in mdoc_node. Allows me to remove some ugly loops in the front-end and duplicate tests in mdoc_action.c. Add a regression test to make sure we're not doing anything bad (more to come).
* Normalise SYNOPSIS behaviour after I gave up on following groff'sKristaps Dzonsons2010-06-076-124/+14
| | | | | | | | | | | | | | | | | | | | | inconsistent behaviour. In short: Some macros are displayed differently in the SYNOPSIS section, particularly Nm, Cd, Fd, Fn, Fo, In, Vt, and Ft. All of these macros are output on their own line. If two such dissimilar macros are pair-wise invoked (except for Ft before Fo or Fn), they are separated by a vertical space, unless in the case of Fo, Fn, and Ft, which are always separated by vertical space. Behaviour ok Jason McIntyre, ingo@. Fallout will be treated case-by-case. I had to clear out some regressions that were testing against groff's stranger behaviours: these will now break, as we don't care about such invocations. Also removed the newline for `Cd' invocation in a non-SYNOPSIS context.
* Fixed -Tascii and -Thtml rendering of `Ft' and `Fo'.Kristaps Dzonsons2010-06-064-0/+99

* Fixed `Fn' newline behaviour and added some regression tests to thisKristaps Dzonsons2010-06-042-0/+37
| | | | | | | extent. Documented `Fn'. Please note the COMPATIBILITY note regarding historic groff.
* Documented `In' in full.Kristaps Dzonsons2010-06-041-0/+24
| | | | | | Fixed `In' to behave properly: it wasn't properly breaking lines, formatting, or really anything else. Noted COMPATIBILITY with OpenBSD's groff, which pukes all over `In'.
* Fixed `Fd' to format in the right way. Found when confused by what theKristaps Dzonsons2010-06-041-0/+22
| | | | | hell `Fd' is supposed to do anyway (answer: it's a historical macro and we shouldn't be doing anything with it anyway).
* Macro lines now infer an `It' if they immediately follow a `Bl -column'Kristaps Dzonsons2010-05-313-0/+43
| | | | | | | or a closed-out `It' block within a `Bl -column' (which only happens when a macro or free-form text is encountered prior to an `It'). Added some regression tests for this behaviour.
* Strengthened constraint for passing into `It'.Kristaps Dzonsons2010-05-311-0/+17
| | | | Added regression test for constrained condition.
* Add ability to interpret initial free-form lines as part of a `BlKristaps Dzonsons2010-05-313-0/+39
| | | | | | | | -column' up until the first `It'. This is UGLY and should have all sorts of warnings, and will. On the one hand, it fits with groff's notion of tabs and tab-spaces. On the other hand, it's not really "free-form" text any more. Note that this does not yet accomodate for macros coming on these lines.
* Add some regression tests.Kristaps Dzonsons2010-05-312-0/+36

* Tweak regression so it doesn't puke on the groff behaviour (allowingKristaps Dzonsons2010-05-301-1/+1
| | | | | open scopes to migrate across tabs) that we probably won't support and is well-known.
* Migrate `Bl -column' phrases to be MDOC_BODY instead of MDOC_HEAD. ThisKristaps Dzonsons2010-05-304-0/+54
| | | | | | | | | | will make it easy for re-entrant parsing of `Ta' macros to fit in with standard closure rules. Added some more regressions for `Bl -column'. Note that one should fail, as documented in the TODO file. Recorded change of AST BNF in mdoc.3.
