* Fix the implementation and documentation of \c (continue text input line).Ingo Schwarze2014-12-021-2/+3
| | | | | In particular, make it work in no-fill mode, too. Reminded by Carsten dot Kunze at arcor dot de (Heirloom roff).
* header cleanup:Ingo Schwarze2014-12-011-3/+2
| | | | | | * add missing forward declarations * remove needless header inclusions * some style unification
* Multiple fixes with respect to .Pf:Ingo Schwarze2014-11-301-2/+3
| | | | | | | * The first argument of .Pf is not parsed. * Normal delimiter handling does not apply to the first argument of .Pf. * Warn if nothing follows a prefix (inspired by groff_mdoc(7)). * In that case, do not suppress spacing.
* Multiple fixes with respect to .Eo:Ingo Schwarze2014-11-271-9/+14
| | | | | | | | 1. Correctly parse stray .Ec without preceding .Eo, avoiding an assertion violation found by jsg@ with afl. 2. Correctly parse .Ec arguments when breaking another block. 3. Correct spacing around closing delimiter when breaking another block. 4. Sync some related formatting control from -Tascii to -Thtml.
* Fix the obsolete .Db (toggle debug mode) macro to ignore its argumentsIngo Schwarze2014-11-271-2/+2
| | | | | and not trigger an assertion when there is more than one argument; the latter found by jsg@ with afl.
* Let .Ao and .Aq render as "<>" after .An and as "\(la\(ra" elsewhere,Ingo Schwarze2014-11-191-3/+5
| | | | just like groff; minibug noticed by bentley@.
* Multiple fixes with respect to in-line macros:Ingo Schwarze2014-11-171-2/+13
| | | | | | | | | | * .No selects the default font; relevant e.g. in .Bf blocks * no need to force empty .Li elements * closing delimiters as leading macro arguments do not suppress space * opening delimiters at the end of a macro line do not suppress space * correctly handle delimiter spacing in -Tman As a side effect, these fixes let mandoc warn about empty .No macros as requested by bentley@.
* Major bugsquashing with respect to -offset and -width:Ingo Schwarze2014-10-301-28/+14
| | | | | | | | | 1. Support specifying the .Bd and .Bl -offset as a macro default width; while here, simplify the code handling the same for .Bl -width. 2. Correct handling of .Bl -offset arguments: unlike .Bd -offset, the arguments "left", "indent", and "indent-two" have no special meaning. 3. Fix the scaling of string length -offset and -width arguments in -Thtml. Triggered by an incomplete documentation patch from bentley@.
* sync Copyright years after merge to OpenBSD; no code changeIngo Schwarze2014-10-101-2/+2

* Don't pretend we have a separate XHTML and HTML mode any more.Kristaps Dzonsons2014-09-271-2/+2
|
* Remove <p> in favour of <div class="spacer">.Kristaps Dzonsons2014-09-271-6/+6
| | | | | | | This is good because <p> is brittle: it can't appear within other block macros. This fixes a regression of the original HTML5 patch as noted by schwarze@ on the tech@ list, 14/8/2014.
* Remove last hard-coded width attribute.Kristaps Dzonsons2014-09-271-8/+1
|
* HTML5-isation: remove more alignments.Kristaps Dzonsons2014-09-271-25/+24
|
* Continue in HTML5-ing by kicking out some hard-coded alignments.Kristaps Dzonsons2014-09-271-5/+3
|
* Kick out "summary" attribute, which isn't HTML5.Kristaps Dzonsons2014-09-271-7/+5
|
* First, add space for default styling for HTML5 (non-fragment) output.Kristaps Dzonsons2014-09-271-7/+5
| | | | | This uses a <style /> block right before the <link /> for the stylesheet. Use this to kick out hardcoded header and footer table widths.
* implement .An -[no]split for -ThtmlIngo Schwarze2014-09-171-4/+28

* Right after .Fl, a middle delimiter triggers an empty scope,Ingo Schwarze2014-08-211-4/+5
| | | | | | | | | | | | just like a closing delimiter. This didn't work in groff-1.15, but it now works in groff-1.22. After being closed by delimiters, .Nm scopes do not reopen. Do not suppress white space after .Fl if the next node is a text node on the same input line; that can happen for middle delimiters. Fixing an issue reported by jmc@.
* Revert previous, as requested by kristaps@.Ingo Schwarze2014-08-141-5/+7
| | | | | | | | | | | | | The .Bf block can contain subblocks, so it has to render as an element that can contain flow content. But <em> cannot contain flow content, only phrasing content. Rendering .Em and .Bf differently would by unfortunate, and closing out .Bf before subblocks and re-opening it afterwards would merely complicate both the C code of the program and the generated HTML code. Besides, converting .Em to semantic HTML markup would require some content to be put into <em> and some into <i>, but we cannot automatically distinguish which is which, so strictly speaking, we can't use semantic HTML here but have to fall back to physical markup. Wonders of HTML...
* Use <em> for .Em and .Bf -emphasis.Ingo Schwarze2014-08-131-7/+5
| | | | | | | | | | | | | | | | | The vast majority of .Em in real-world manuals is stress emphasis, for which <em> is the correct markup. Admittedly, there are some instances of .Em usage for alternate quality, for which <i> would be a better match. Most of these are technical terms that neither allow semantic markup nor are keywords - for the latter, .Sy would be preferable. A typical example is that the shell breaks input into .Em words . Alternate voice or mood, which would also require <i>, is almost absent from manuals. We cannot satisfy both stress emphasis and alternate quality, so pick the one that fits more often and looks less wrong when off. Patch from Guy Harris <guy at alum dot mit dot edu>. ok joerg@ bentley@
* Get rid of HAVE_CONFIG_H, it is always defined; idea from libnbcompat.Ingo Schwarze2014-08-101-3/+1
| | | | | | Include <sys/types.h> where needed, it does not belong in config.h. Remove <stdio.h> from config.h; if it is missing somewhere, it should be added, but i cannot find a *.c file where it is missing.
* Bring the handling of defective prologues even closer to groff,Ingo Schwarze2014-08-061-4/+9
| | | | | | | | | | | | in particular relaxing the distinction between prologue and body and further improving messages. * The last .Dd wins and the last .Os wins, even in the body. * The last .Dt before the first body macro wins. * Missing title in .Dt defaults to UNTITLED. Warn about it. * Missing section in .Dt does not default to 1. But warn about it. * Do not warn multiple times about the same mdoc(7) prologue macro. * Warn about missing .Os. * Incomplete .TH defaults to empty strings. Warn about it.
* Clarity with respect to floating point handling:Ingo Schwarze2014-08-011-3/+3
| | | | | | Write double constants as double rather than integer literals. Remove useless explicit (double) cast done at one place and nowhere else. No functional change.
* Various improvements related to .Ex and .Rv:Ingo Schwarze2014-07-301-25/+31
| | | | | | | | | | * let .Nm fall back to the empty string, not to UNKNOWN * never let .Rv copy an argument from .Nm * avoid spurious \fR after empty .Nm in -Tman * correct handling of .Ex and .Rv in -Tman * correct the wording of the output for .Rv without arguments * use non-breaking spaces in .Ex and .Rv output where required * split MANDOCERR_NONAME into a warning for .Ex and an error for .Nm
* When .Sm is called without an argument, groff toggles the spacing mode,Ingo Schwarze2014-07-021-15/+8
| | | | | so let us do the same for compatibility. Using this feature is of course not recommended except in manual page obfuscation contests.
* Implement the obsolete macros .En .Es .Fr .Ot for backward compatibility,Ingo Schwarze2014-07-021-9/+24
| | | | | since this is hardly more complicated than explicitly ignoring them as we did in the past. Of course, do not use them!
* Audit strlcpy(3)/strlcat(3) usage.Ingo Schwarze2014-04-231-17/+22
| | | | | | | | | | | | | * Repair three instances of silent truncation, use asprintf(3). * Change two instances of strlen(3)+malloc(3)+strlcpy(3)+strlcat(3)+... to use asprintf(3) instead to make them less error prone. * Cast the return value of four instances where the destination buffer is known to be large enough to (void). * Completely remove three useless instances of strlcpy(3)/strlcat(3). * Mark two places in -Thtml with XXX that can cause information loss and crashes but are not easy to fix, requiring design changes of some internal interfaces. * The file mandocdb.c remains to be audited.
* fix unchecked snprintf(3) in page header printing:Ingo Schwarze2014-04-201-3/+7
| | | | | the length of the title is unknown, and speed doesn't matter here, so use asprintf/free rather than a static buffer
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-305/+185
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* Implement the roff(7) .ll (line length) request.Ingo Schwarze2014-03-301-2/+12
| | | | | Found by naddy@ in the textproc/enchant(1) port. Of course, do not use this in new manuals.
* It turns out SYNOPSIS mode does not imply .Bk in general,Ingo Schwarze2013-12-241-2/+2
| | | | | | but only within .Nm blocks. Simplify the code accordingly. Triggered by research done by Franco Fichtner.
* When deciding whether two consecutive macros are on the same input line,Ingo Schwarze2013-12-241-8/+4
| | | | | | | | we have to compare the line where the first one *ends* (not where it begins) to the line where the second one starts. This fixes the bug that .Bk allowed output line breaks right after block macros spanning more than one input line, even when the next macro follows on the same line.
* Cleanup naming of local variables to make the code easier on the eye:Ingo Schwarze2012-11-171-29/+30
| | | | | | | | Settle for "struct man *man", "struct mdoc *mdoc", "struct meta *meta" and avoid the confusing "*m" which was sometimes this, sometimes that. No functional change. ok kristaps@ some time ago
* .Sq should use curly right quotes in HTML output to match its curlyIngo Schwarze2012-08-121-4/+4
| | | | | | | | | left quotes. Also, properly reinitialize the styles attribute string buffer for each column in a table so that the attributes don't accumulate. Patch from Matthew@ Dempsky, tweaked by me; OpenBSD rev. 1.66.
* Correct .Eo spacing:Ingo Schwarze2011-11-031-2/+6
| | | | | no space between the delimiters and the enclosed text. The mdoc_html.c part was added by kristaps; ok kristaps@.
* Remove a bunch of useless assignments,Ingo Schwarze2011-10-161-2/+2
| | | | | | | and assert that print_bvspace cannot be called on NULL pointers. No change in behaviour, none of these were bugs, but the code becomes easier to understand. Based on a clang report posted by joerg@; ok kristaps@.
* Always print <table> column widths in -T[x]html;Ingo Schwarze2011-10-091-38/+18
| | | | | if desired, they can be overridden in the CSS file. Suggested by kristaps@, and i always like to simplify code.
* Add the -Ofragment option to -T[]x]html. This accomodates for embeddingKristaps Dzonsons2011-10-051-16/+17
| | | | | manual output in existing HTML or XHTML documents, e.g., when invoking mandoc from an SSI or CGI.
* Make sure that `Ql' literalises its arguments in -T[x]html. Found whenKristaps Dzonsons2011-08-261-2/+6
| | | | doing manpages.bsd.lv stuff.
* Align `-offset indent' and `D1' by forcing BLOCKQUOTE to have a 5exKristaps Dzonsons2011-08-181-6/+3
| | | | | | | | | margin. This is dubious: the HTML4 spec specifically says that BLOCKQUOTE shouldn't be abused for indentation, which is exactly what we do. However, `D1' needs indentation and it's the only way to force text browsers to do so. Alternatives? Also remove the unused HALFINDENT defines while here.
* Have `Li' be correctly monospaced in -T[x]html. Also make sure thatKristaps Dzonsons2011-08-181-2/+2
| | | | | `Li' prints as a CODE tag and the style-sheet has the `lit' class apply to multiple tag types.
* Allow `Sx' and `Ss' to have child nodes. Fixes manuals in NetBSD.Kristaps Dzonsons2011-08-101-12/+22
| | | | | | Originally pointed out by joerg@ then again by Thomas Klausner by way of Nicolas Joy. Note: don't use these constructions as you can't link to the sections with `Sx'.
* Flip on equation printing for -T[x]html.Kristaps Dzonsons2011-07-231-5/+2

* Flip eqn into using parsed nodes. I've temporarily disabled printingKristaps Dzonsons2011-07-211-3/+3
| | | | | | | these in the front-ends except for -Ttree, which will display the parsed tree. While here, fix that quoted strings aren't scanned for replacement parts.
* The bufcat() function in -T[x]html was eating one byte off the end of itsKristaps Dzonsons2011-07-041-1/+3
| | | | | | concatenated string. This for some reason hasn't been found before now... ? Anyway, fixed, and make the IDs created again be correctly prefixed by a letter as per the HTML spec.
* First fix how `sp 1' doesn't imply `1v' (it now does) and that 1Kristaps Dzonsons2011-06-291-3/+4
| | | | | | followed by non-digits, e.g. `1g', really means `1'. Next, fix some spacing issues where `sp' was invoked in -man after sections or subsections. Make sure this behaviour is mirrored in -Thtml.
* Have -T[x]html print out the link target for `Lk' if no link title isKristaps Dzonsons2011-06-161-4/+5

* Clean-up fallout: differentiate ID's and HREF's (where to put the `#').Kristaps Dzonsons2011-05-171-1/+2
| | | | Make buffmt functions internally bufinit(), too.
* Cleanups in -T[x]html: make html_idcat() use the buffer and be calledKristaps Dzonsons2011-05-171-29/+26
| | | | | | bufcat_id(), then collapse it into a little function without so much crap. Next, make bufinit() only be called when we really need to do so, and not simply before pre/post calls.
* Clean-ups in -T[x]html: inline print_num(), as it was just a singleKristaps Dzonsons2011-05-171-2/+2
| | | | | | | | | | conditional; same for print_xmltype() and print_doctype(), same reason; make bufncat() be static, as it was only being called from html.c; have bufcat() simply call through to strlcat(). Finally, assert() whenever we truncate. Also rename buffmt() -> bufcat_fmt() to differentiate from buffmt_man et al., which do not concatenate.
