* Copy tagged strings before marking hyphens as breakable.Ingo Schwarze2020-04-0216-22/+37
| | | | For example, this makes ":tCo-processes" work in ksh(1).
* Just like we are already doing it in HTML output, automatically tagIngo Schwarze2020-04-0120-5/+84
| | | | | | | 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.
* test skipping of initial hyphens and minus signs in automatic tags;Ingo Schwarze2020-03-215-5/+41
| | | | related to tags.c rev. 1.30
* Split tagging into a validation part including prioritizationIngo Schwarze2020-03-1381-26/+1078
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* 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 Schwarze2020-02-2731-22/+543
| | | | | | | | | | | | | | 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@.
* Align to the new, sane behaviour of the groff_mdoc(7) .Dd macro:Ingo Schwarze2020-01-1913-23/+35
| | | | | | | | without an argument, use the empty string, and always concatenate all arguments, no matter their number. This allows reducing the number of arguments of mandoc_normdate() and some other simplifications, at the same time polishing some error messages by adding the name of the macro in question.
* Simplify maintainer targets in OpenBSD: EQN and TBL variablesIngo Schwarze2020-01-081-2/+2
| | | | | | no longer exist and NROFF/NOPTS were replaced with GROFF/GOPTS. This doesn't change how things work in the protable version of the test suite.
* 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.
* adapt to new <p> output logic (html.c rev. 1.260)Ingo Schwarze2019-09-036-18/+6

* When parsing a tab character that is not preceded by a space characterIngo Schwarze2019-07-114-5/+6
| | | | | | | | | | | | | | | | on an .It -column line, args() sets the MDOC_PHRASEQL flag to Quote the Last word of the Phrase. Even if it turns out this quoting is not needed because the word is already quoted for other reasons, clear the flag at the end of parsing the phrase, such that the flag does not leak to the next phrase. This patch fixes the bug that the trailing Macro on a line of the form .It "word<tab>word" Ta word Macro<eol> was incorrectly considered quoted and hence not parsed. Bug found by Havard Eidnes (he@) with the NetBSD gettytab(5) manual page: https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=54361 Reported via Thomas Klausner (wiz@).
* Wrap .Sh/.SH sections and .Ss/.SS subsections in HTML <section> elementsIngo Schwarze2019-03-012-0/+6
| | | | | | 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 Schwarze2019-01-112-11/+10
| | | | | | | 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 Schwarze2019-01-0729-23/+429
| | | | | | | | | | | | | | | | | | | 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.
* Test interaction of low-level roff(7) filling requests with .Bd in generalIngo Schwarze2019-01-047-12/+97
| | | | and filling in .Bd -centered in particular; related to mdoc_term.c rev. 1.372.
* Rename mandoc_getarg() to roff_getarg() and pass it the roff parserIngo Schwarze2018-12-2125-12/+341
| | | | | | | | | | | | | | | | | | struct as an argument such that after copy-in, it can call roff_expand() once again, which used to be called roff_res() before this. This fixes a subtle low-level roff(7) parsing bug reported by Fabio Scotoni <fabio at esse dot ch> in the 4.4BSD-Lite2 mdoc.samples(7) manual page, because that page used an escaped escape sequence in a macro argument. To expand escaped escape sequences in quoted mdoc(7) arguments, too, stop bypassing the call to roff_getarg() in mdoc_argv.c, function args() for this case. This does not solve the case of escaped escape sequences in quoted .Bl -column phrases yet. Because roff_expand() can make the string longer, roff_getarg() can no longer operate in-place but needs to malloc(3) the returned string. In the high-level parsers, free(3) that string after processing it.
* Clean up the validation of .Pp, .PP, .sp, and .br. Make sure allIngo Schwarze2018-12-042-2/+4
| | | | | | | | | | | | | | 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.

* Remove the implicit display feature of .Lk because it was inconsistentIngo Schwarze2018-01-131-3/+2
| | | | | | | | | across output devices, counter-intuitive, and resulted in ugly output for many real-world manual pages. Always format even long links in-line. I already committed a similar change to groff. OK jmc@, bentley@, and the original author of the feature, Werner Lemberg <wl@gnu.org>.
* disable .Xr -Tlint test for now,Ingo Schwarze2017-07-281-0/+3

* Messages of the -Wbase level now print STYLE:. Since thisIngo Schwarze2017-07-04834-1805/+1641
| | | | | | | | 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.

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.

* 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.
