* Copy tagged strings before marking hyphens as breakable.Ingo Schwarze2020-04-026-6/+20
| | | | For example, this makes ":tCo-processes" work in ksh(1).
* Just like we are already doing it in HTML output, automatically tagIngo Schwarze2020-04-017-5/+57
| | | | | | | 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.
* Fully support explicit tagging of .Sh and .Ss.Ingo Schwarze2020-02-275-3/+82
| | | | | | | | | | | | | | | | | | | | | | | | | This fixes the offset of two lines in terminal output and this improves HTML output by putting the id= attribute and <a> element into the respective <h1> or <h2> element rather than writing an additional <mark> element. To that end, introduce node flags NODE_ID (to make the node a link target, for example by writing an HTML id= attribute or by calling tag_put()) and NODE_HREF (to make the node a link source, used only in HTML output, used only to write an <a class="permalink"> element). In particular: * In the validator, generalize the concept of the "next node" such that it also works before .Sh and .Ss. * If the first argument of .Tg is empty, don't forget to complain if there are additional arguments, which will be ignored. * In the terminal formatter, support writing of explicit tags for all kinds of nodes, not just for .Tg. * In deroff(), allow nodes to have an explicit string representation even when they aren't text nodes. Use this for explicitly tagged section headers. Suprisingly, this is sufficient to make HTML output work, without explicit code changes in the HTML formatter. * In syntax tree output, display NODE_ID and NODE_HREF.
* Introduce the concept of nodes that are semantically transparent:Ingo Schwarze2020-02-274-2/+37
| | | | | | | | | | | | | | 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@.

* Wrap .Sh/.SH sections and .Ss/.SS subsections in HTML <section> elementsIngo Schwarze2019-03-011-0/+4
| | | | | | as recommended for accessibility by the HTML 5 standard. Triggered by a similar, but slightly different suggestion from Laura Morales <lauretas at mail dot com>.
* Remove the HTML title= attributes which harmed accessibility andIngo Schwarze2019-01-111-2/+2
| | | | | | | violated the principle of separation of content and presentation. Instead, implement the tooltips purely in CSS. Thanks to John Gardner <gardnerjohng at gmail dot com> for suggesting most of the styling in the new ::before rules.
* Represent mdoc(7) .Pp (and .sp, and some SYNOPSIS and .Rs features)Ingo Schwarze2019-01-075-2/+73
| | | | | | | | | | | | | | | | | | | by the <p> HTML element and use the html_fillmode() mechanism for .Bd -unfilled, just like it was done for man(7) earlier, finally getting rid both of the horrible <div class="Pp"></div> hack and of the worst HTML syntax violations caused by nested displays. Care is needed because in some situations, paragraphs have to remain open across several subsequent macros, whereas in other situations, they must get closed together with a block containing them. Some implementation details include: * Always close paragraphs before emitting HTML flow content. * Let html_close_paragraph() also close <pre> for extra safety. * Drop the old, now unused function print_paragraph(). * Minor adjustments in the top-level man(7) node formatter for symmetry. * Bugfix: .Ss heads suspend no-fill mode, even though .Ss doesn't end it. * Bugfix: give up on .Op semantic markup for now, see the comment.
* Clean up the validation of .Pp, .PP, .sp, and .br. Make sure allIngo Schwarze2018-12-041-1/+1
| | | | | | | | | | | | | | combinations are handled, and are handled in a systematic manner. This resolves some erratic duplicate handling, handles a number of missing cases, and improves diagnostics in various respects. Move validation of .br and .sp to the roff validation module rather than doing that twice in the mdoc and man validation modules. Move the node relinking function to the roff library where it belongs. In validation functions, only look at the node itself, at previous nodes, and at descendants, not at following nodes or ancestors, such that only nodes are inspected which are already validated.
* Do not test .Xr here. It is not what this directory should focus on,Ingo Schwarze2017-07-286-28/+20
| | | | and it is causing too much trouble in -portable.
* Avoid cross reference to mandoc(1) because it may cause a messageIngo Schwarze2017-07-206-12/+12
| | | | | on other operating systems where mandoc is not installed, causing the test to fail in the portable test suite.
* Messages of the -Wbase level now print STYLE:. Since thisIngo Schwarze2017-07-0448-111/+87
| | | | | | | | 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.

* style message about missing RCS ids; inspired by mdoclintIngo Schwarze2017-06-1712-0/+12

* Style message about legacy man(7) date format in mdoc(7) documentsIngo Schwarze2017-06-1112-0/+12

* 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.
* Really commit some files that failed to get committed in this commit:Ingo Schwarze2017-03-091-2/+0
| | | | | | | 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.

* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-0830-0/+224
Both kristaps@ and wiz@ repeated asked for this, literally for years.
