* Separate the place to put the <a href> permalink (now markedIngo Schwarze2020-04-071-7/+6
| | | | | | | with NODE_HREF) from the target element of the link (still marked with NODE_ID). In many cases, use this to move the target to the beginning of the paragraph, such that readers don't get dropped into the middle of a sentence.
* Just like we are already doing it in HTML output, automatically tagIngo Schwarze2020-04-011-0/+2
| | | | | | | section and subsection headers in terminal output, too. Even though admittedly, commands like "/SEE" and "/ Subsec" work, too, there is no downside, and besides, with the recent improvements in the tagging framework, implementation cost is negligible.
* Split tagging into a validation part including prioritizationIngo Schwarze2020-03-136-2/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in tag.{h,c} and {mdoc,man}_validate.c and into a formatting part including command line argument checking in term_tag.{h,c}, html.c, and {mdoc|man}_{term|html}.c. Immediate functional benefits include: * Improved prioritization of automatic tags for .Em and .Sy. * Avoiding bogus automatic tags when .Em, .Fn, or .Sy are explicitly tagged. * Explicit tagging of .Er and .Fl now works in HTML output. * Automatic tagging of .IP and .TP now works in HTML output. But mainly, this patch provides clean earth to build further improvements on. Technical changes: * Main program: Write a tag file for ASCII and UTF-8 output only. * All formatters: There is no more need to delay writing the tags. * mdoc(7)+man(7) formatters: No more need for elaborate syntax tree inspection. * HTML formatter: If available, use the "string" attribute as the tag. * HTML formatter: New function to write permalinks, to reduce code duplication. Style cleanup in the vicinity while here: * mdoc(7) terminal formatter: To set up bold font for children, defer to termp_bold_pre() rather than calling term_fontpush() manually. * mdoc(7) terminal formatter: Garbage collect some duplicate functions. * mdoc(7) HTML formatter: Unify <code> handling, delete redundant functions. * Where possible, use switch statements rather than if cascades. * Get rid of some more Yoda notation. The necessity for such changes was first discussed with kn@, but i didn't bother him with a request to review the resulting -673/+782 line patch.
* Introduce the concept of nodes that are semantically transparent:Ingo Schwarze2020-02-274-2/+57
| | | | | | | | | | | | | | they are skipped when looking for previous or following high-level macros. Examples include roff(7) .ft, .ll, and .ta, mdoc(7) .Sm and .Tg, and man(7) .DT and .PD. Use this concept for a variety of improved decisions in various validators and formatters. While here, * remove a few const qualifiers on struct arguments that caused trouble; * get rid of some more Yoda notation in the vicinity; * and apply some other stylistic improvements in the vicinity. I found this class of issues while considering .Tg patches from kn@.
* Improve validation of function names:Ingo Schwarze2019-09-134-3/+63
| | | | | | 1. Relax checking to accept function types of the form "ret_type (fname)(args)" (suggested by Yuri Pankov <yuripv dot net>). 2. Tighten checking to require the closing parenthesis.
* Messages of the -Wbase level now print STYLE:. Since thisIngo Schwarze2017-07-0435-73/+68
| | | | | | | | causes horrible churn anyway, profit of the opportunity to stop excessive testing, such that this is hopefully the last instance of such churn. Consistently use OpenBSD RCS tags, blank .Os, blank fourth .TH argument, and Mdocdate like everywhere else. Use -Ios=OpenBSD for platform-independent predictable output.

* Macro argument quoting does not prevent recognition of punctuationIngo Schwarze2017-05-306-12/+24
| | | | | | | | | | | 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.
* Now that markdown output is tested for almost everything, test allIngo Schwarze2017-03-081-2/+0
| | | | | | 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.

* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-0825-0/+511
| | | | | Both kristaps@ and wiz@ repeated asked for this, literally for years.
* Normalise SYNOPSIS behaviour after I gave up on following groff'sKristaps Dzonsons2010-06-071-32/+0
| | | | | | | | | | | | | | | | | | | | | 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 Dzonsons2010-06-061-0/+32
