1. Do not put ASCII_HYPH (0x1c) into the tag file. That happened when tagging a string containing '-' on an input text line, most commonly in man(7) .TP next line scope. 2. Do not let "\-" end the tag. In both cases, translate ASCII_HYPH and "\-" to plain '-' for output. For example, this improves handling of unbound.conf(5). These two bugs were found thanks to a posting by weerd@.

If a node is tagged explicitly, skip implicit tagging for that node. Apart from making sense in the first place, this fixes an assertion failure that happened when the calculated implicit tag did not match the string value of the first child of the node, Bug found by tb@ using afl(1).

When the last file formatted yielded no tags, the tags file got deleted before starting the pager, even when earlier input files had written to it; thanks to weerd@ for reporting that bug. Since we now generate tags for section headers, we almost always generate at least some. Consequently, while fixing the above bug, simplify the code by never deleting the tags file before the pager exits, not even in the rare case that the file happens to be empty. Hence, this patch is -75 +63 LOC even though it fixes two bugs. While deleting the output files belongs after exit from the pager, closing them should be done before it is started. Collect the related code, which was scattered in various places, to where it belongs, in a dedicated function in the term_tag.c module. As a side benefit, never fclose(2) stdout, only dup2(2) to it. Similarly, when the -O tag argument wasn't found in the last file formatted, there was a complaint about "no such tag" even when the argument did occur in earlier files. Fix that by looking for a matching tag after every formatted file rather than just once at the very end. Given that command line arguments aren't properties of the file(s) being formatted, that check is a job for the main program, not for the formatters, so while fixing the check, move it from term_tag.c to main.c.

Split tagging into a validation part including prioritization 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 a new mdoc(7) macro .Tg ("tag") to explicitly mark a place as defining a term. Please only use it when automatic tagging does not work. Manual page authors will not be required to add the new macro; using it remains optional. HTML output is still rudimentary in this version and will be polished later. Thanks to kn@ for reminding me that i have been considering since BSDCan 2014 whether something like this might be useful. Given that possibilities of making automatic tagging better are running out and there are still several situations where automatic tagging cannot do the job, i think the time is now ripe. Feedback and no objection from millert@; OK espie@ inoguchi@ kn@.

Slowly start implementing tagging support for man(7) pages, even though it is obvious that this can never become as good as for mdoc(7) pages. As a first step, tag alphabetic arguments of .IP macros, which are often used for lists of options and keywords. Try "man -O tag=g as" to get the point. Thanks to Leah Neukirchen for recently reminding me that exploring how much can be done in this respect may be worthwhile: it is likely to slightly improve usability while adding only small amounts of relatively straightforward code.

If no tags were generated at all, unlink(2) the empty tags file as soon as the condition can be detected and do not pass it to less(1). This may happen for man(7) pages, for preformatted pages, and for very simple pages like true(1). The main benefit is that :t inside less(1) yields the clearer diagnostic message "No tags file" rather than the mildly confusing "No such tag in tags file": the latter might encourage further, futile attempts to jump to other tags. Improvement suggested by Leah Neukirchen <leah at vuxu dot org> from The Void.

Some time ago, i simplified mandoc_msg() such that it can be used everywhere and not only in the parsers. For more uniform messages, use it at more places instead of err(3), in particular in the main program. While here, integrate a few trivial functions called at exactly one place into the main option parser, and let a few more functions use the normal convention of returning 0 for success and -1 for error.

In -T locale (the default), -T ascii, and -T utf8 mode, provide a new output option -O tag[=term] to move right to the definition of "term" when opening the manual page in a pager, effectively porting the -T html fragment name feature - https://man.openbsd.org/ksh#ulimit - to the terminal. Try: $ man -O tag uvm_sysctl $ man -O tag=ulimit ksh $ man -O tag 3 compress Feature development triggered by a question from kn@. Klemens also tested, provided feedback that resulted in improvements, and provided an OK.

The ctags(1) file format uses whitespace as a field delimiter, and there is no escaping mechanism, so tags cannot contain whitespace. Consequently, we used to simply not tag macro arguments containing space characters. Instead, let's tag the first word, unless there is a proper match for that word somewhere else. For example, this makes ":tquery" work in ntpd.conf(5). Feature suggested by kn@, who also thinks the implementation looks reasonable and works in his testing.

Initial, still somewhat experimental implementation to leverage less(1) -T and :t ctags(1)-like functionality to jump to the definitions of various terms inside manual pages. To be polished in the tree, so bear with me and report issues. Technically, if less(1) is used as a pager, information is collected by the mdoc(7) terminal formatter, first stored using the ohash library, then ultimately written to a temporary file which is passed to less via -T. No change intended for other output formatters or when running without a pager. Based on an idea from Kristaps using feedback from many, in particular phessler@ nicm@ millert@ halex@ doug@ kspillner@ deraadt@.
