* In HTML, display straight quotes, not curly quotes, for Qq/Qo/Qc macros.Ingo Schwarze2019-12-111-3/+7
| | | | | | This is the intended behavior and already the case in terminal output. Incorrect output noticed by Eldred Habert. Patch from bentley@.
* Fix line breaking in no-fill mode (.Bd -unfilled/<pre>),Ingo Schwarze2019-09-151-20/+26
| | | | | | | | | | | | | which apparently didn't work since the .Pp/<p> reorg. The new logic is more similar to what the terminal formatter does: 1. Before a node that starts a new mdoc(7) input line, start a new HTML output line. 2. An empty input line or a .Pp causes an empty output line. 3. Nothing needs to be done at the end of a node. Severe misformatting was reported in table(5) by Edgar Pettijohn <edgar at pettijohn dash web dot com> on misc@.
* Format .Nd with more logically with <span> rather than <div>; after all,Ingo Schwarze2019-09-031-3/+1
| | | | | | | | | | it is supposed to be a one-line description. For the case where .Nd generates flow content (which is very bad style but syntactically valid), rely on the new feature of html_close_paragraph() to close out the <span> prematurely, effectively moving the flow content out of the .Nd for HTML presentation. For the final closing, also rely on the new html_close_paragraph() functionality, this time triggered by the subsequent block, which will typically be .Sh SYNOPSIS.

* Wrap .Sh/.SH sections and .Ss/.SS subsections in HTML <section> elementsIngo Schwarze2019-03-011-1/+5
| | | | | | 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>.
* The .UR and .MT blocks in man(7) are represented by <a> elementsIngo Schwarze2019-01-181-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | which establish phrasing context, but they can contain paragraph breaks (which is relevant for terminal formatting, so we can't just change the structure of the syntax tree), which are respresented by <p> elements and cannot occur inside <a>. Fix this by prematurely closing the <a> element in the HTML formatter. This menas that the clickable text in HTML output is shorter than what is represented as the link text in terminal output, but in HTML, it is frankly impossible to have the clickable area of a hyperlink extend across a paragraph break. The difference in presentation is not a major problem, and besides, paragraph breaks inside .UR are rather poor style in the first place. The implementation is quite tricky. Naively closing out the <a> prematurely would result in accessing a stale pointer when later reaching the physical end of the .UR block. So this commit separates visual and structural closing of "struct tag" stack items. Visual closing means that the HTML element is closed but the "struct tag" remains on the stack, to avoid later access to a stale pointer and to avoid closing the same HTML element a second time later. This also needs reference counting of pointers to "struct tag" stack items because often more than one child holds a pointer to the same parent item, and only the outermost child can safely do the physical closing. In the whole corpus of nearly half a million manual pages on man.openbsd.org, this problem occurs in exactly one page: the groff(1) version 1.20.1 manual contained in DragonFly-3.8.2, which contains a formatting error triggering the bug.

* Remove the HTML title= attributes which harmed accessibility andIngo Schwarze2019-01-111-42/+42
| | | | | | | 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.
* After years of gnashing of teeth, i finally found a way to avoidIngo Schwarze2019-01-101-12/+0
| | | | | | | | | | | | | | | | | | having to write empty list elements for non-compact .Bl -tag lists: 1. Add margin-bottom to the <dd>. Note that margin-top on the <dt> doesn't work because it would put a short <dt> lower than the <dd>; margin-bottom on the <dt> doesn't work because it would put vertical space before the <dd> for a long <dt>; and margin-top on the <dd> doesn't work because it would put a short <dt> higher than the <dd>. Only margin-bottom on the <dd> has none of these adverse effects. 2. Of course, margin-bottom on the <dd> fails to take care of the vertical spacing before the first list element, so implement that separately by margin-top on the <dl>. 3. For .Bl -tag -compact, reset both to zero.
* Represent mdoc(7) .Pp (and .sp, and some SYNOPSIS and .Rs features)Ingo Schwarze2019-01-071-93/+131
| | | | | | | | | | | | | | | | | | | 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.
* Cleanup, no functional change:Ingo Schwarze2018-12-311-12/+3
| | | | | | | | | | Stop trying to keep fill mode state locally in the mdoc HTML formatter, rely on the state stored in the nodes instead. Note that the .Bd -literal code is buggy. Nested literal displays result in nested <pre> elements, which violates HTML syntax. But i'm not yet fixing bugs in this commit, i'm merely deleting code which has no effect.
* Cleanup, no functional change:Ingo Schwarze2018-12-301-5/+5
| | | | | | | | | | | | | | The struct roff_man used to be a bad mixture of internal parser state and public parsing results. Move the public results to the parsing result struct roff_meta, which is already public. Move the rest of struct roff_man to the parser-internal header roff_int.h. Since the validators need access to the parser state, call them from the top level parser during mparse_result() rather than from the main programs, also reducing code duplication. This keeps parser internal state out of thee main programs (five in mandoc portable) and out of eight formatters.
* bugfix: make the static class buffer long enoughIngo Schwarze2018-12-251-1/+1

* In the TOC, close <a> before opening <ul>.Ingo Schwarze2018-12-221-1/+2
| | | | Simplified version of a bugfix patch from rapha@.
* Yet another round of improvements to manual font selection.Ingo Schwarze2018-12-161-0/+1
| | | | | | | | | Unify handling of \f and .ft. Support \f4 (bold+italic). Support ".ft BI" and ".ft CW" for terminal output. Support the .ft request in HTML output. Reject the bogus fonts \f(C1, \f(C2, \f(C3, and \f(CP. In regress.pl, only strip leading whitespace in math mode.
* Cleanup, no functional change:Ingo Schwarze2018-12-131-1/+0
| | | | | | | | | | Split the top level parser interface out of the utility header mandoc.h, into a new header mandoc_parse.h, for use in the main program and in the main parser only. Move enum mandoc_os into roff.h because struct roff_man is the place where it is stored. This allows removal of mandoc.h from seven files in low-level parsers and in formatters.
* In the validators, translate obsolete macro aliases (Lp, Ot, LP, P)Ingo Schwarze2018-12-031-3/+9
| | | | | | to the standard forms (Pp, Ft, PP) up front, such that later code does not need to look for the obsolete versions. This reduces the risk of incomplete handling.

* Remove more pointer arithmetic passing via regions outside the arrayIngo Schwarze2018-08-171-7/+7

* Drop explicit, constant style=margin-left attribute on .Bf blocks.Ingo Schwarze2018-06-251-1/+1

* Do not write <colgroup> elements. Their only purpose is to enforceIngo Schwarze2018-06-251-21/+1
| | | | | | author-specified column widths, which can harm responsive design and provide no real benefit: HTML rendering engines usually do just fine automatically selecting appropriate column widths.
* In HTML output, for lists that have an -indent argument, just useIngo Schwarze2018-06-101-16/+9
| | | | | | | | | | | | | a uniform indentation in CSS adapted to the viewport width and ignore the value of the argument taken from mdoc(7). While author-specified widths somewhat work as a micro-optimization in terminal and typeset output, they are nothing but harmful in HTML style= attributes because they break responsive design, whereas using a reasonable default indent almost never results in ugly output. Admittedly, the author-specified width might occasionally look even better, but only slightly so, and only for some viewport sizes. Based on guidance provided by John Gardner.
* Ignore author-specified -width arguments for -tag and -hang listsIngo Schwarze2018-05-291-6/+5
| | | | | | | | | | | | | | | in HTML output. For terminal and typeset output, such arguments kind of work to achieve presentational micro-optimization. But for HTML, they only do harm. Large increases usually look ugly. Large reductions are impossible since the default is not large in the first place. Small tweaks in either direction are not important; at least not important enough to justify making responsive design impossible. Triggered by John Gardner's suggestion to further reduce style= attributes in the HTML code, in particular those containing hard-coded lengths.
* Do not write duplicate id= attributes, they violate HTML syntax.Ingo Schwarze2018-05-251-16/+5

* Fix a long-standing issue:Ingo Schwarze2018-05-091-14/+10
| | | | | | | | | Some macros (Nd, Oo) can contain blocks but rendered as elements that can only contain phrasing content, resulting in invalid HTML nesting. Switch them to <div>. Also move the related "display: inline" style from the HTML to the CSS. Reminded during a conversation with John Gardner.
* Eliminate the class=It-* attributes.Ingo Schwarze2018-05-081-53/+12

* Split -Wstyle into -Wstyle and the even lower -Wbase, and addIngo Schwarze2017-06-241-0/+1
| | | | | | | | | | | | | | | -Wopenbsd and -Wnetbsd to check conventions for the base system of a specific operating system. Mark operating system specific messages with "(OpenBSD)" at the end. Please use just "-Tlint" to check base system manuals (defaulting to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the manuals of portable software projects you maintain that are not part of OpenBSD base, to avoid bogus recommendations about base system conventions that do not apply. Issue originally reported by semarie@, solution using an idea from tedu@, discussed with jmc@ and jca@.
* Fix a regression in the previous revision:Ingo Schwarze2017-06-191-2/+6

| | | | | | Just let HTML <table> do its work of selecting the needed width. <Anton dot Lindqvist at gmail dot com> reported that the manually calculated width was insufficient in some manual pages.
* Make the tag column in .Bl -tag lists wider:Ingo Schwarze2017-05-121-4/+4
| | | | | | 1. I forgot about the 2n padding between tag and body. 2. The factor 1.1 was too small for bold fold, make it *1.15 + 1n. Ugliness spotted by tb@.
