* Improve formatting of broken blocks in -Tman,Ingo Schwarze2014-03-301-2/+11
| | | | | somewhat similar to what mdoc_term.c already does for -Tascii. OpenBSD rev. 1.58.
* Allow ERRORS in section 4; OpenBSD rev. 1.121.Ingo Schwarze2014-03-301-2/+4
|
* Support relative arguments to .ll (increase or decrease line length).Ingo Schwarze2014-03-307-15/+56
|
* Implement the roff(7) .ll (line length) request.Ingo Schwarze2014-03-3019-11/+109
| | | | | Found by naddy@ in the textproc/enchant(1) port. Of course, do not use this in new manuals.
* Allow leading and trailing vertical lines,Ingo Schwarze2014-03-283-4/+16
| | | | | | | and format them in the same way as groff. While here, do not require whitespace before vertical lines in layout specifications. Issues found by bentley@ in mpv(1).
* Properly initialize malloc(3)ed memory.Ingo Schwarze2014-03-281-0/+1
| | | | | With this bug fix, partly unitialized memory could sometimes be returned, sometimes causing crashes by bogus free(3)s in apropos(1).
* Without bloating mandoc(1) itself, let mandocdb(8) support filesIngo Schwarze2014-03-261-16/+80
| | | | | called manN/X.N.gz and catN/X.0.gz, reading them through a pipe(2) from gunzip(1) -c. Asked for by various people in the past.
* Improve error reporting.Ingo Schwarze2014-03-261-33/+51
| | | | | | | | Simplify combining a custom format string with perror(), avoiding many manual calls to strerror(errno). For low-level failures, report attempted function calls. Do not abuse the say() filename argument for files outside the basedir, and even less for other text.
* Skip leading escape sequences in man_deroff(). Helps indexing ofIngo Schwarze2014-03-231-4/+11
| | | | some manuals containing overzealous escaping in their NAME section.
* Retire the old concat() function.Ingo Schwarze2014-03-231-77/+26
| | | | | | | | For .Sh, i wasn't even needed at all. For .Dd, .Nm, and .Os, use the new mdoc_deroff() instead. This gets rid of the last limited-size static buffers in this file, hence eliminates the last explicit MANDOCERR_MEM throwers here, and it shortens the code by 50 lines.
* If an .Nd block contains macros, avoid fragmented entries in mandocdb(8),Ingo Schwarze2014-03-233-25/+44
| | | | instead use the .Nd content recursively.
* If a man(7) NAME section contains macros, avoid truncated or emptyIngo Schwarze2014-03-233-46/+49
| | | | | | entries for .Nd in mandocdb(8), instead use the macro content recursively. This improves indexing of more than 200 manuals in Xenocara, i.e. more than 15%, in particular GL and some Xkb.
* needs mandoc_aux, tooIngo Schwarze2014-03-231-0/+1
|
* avoid repetitive code for asprintf error handlingIngo Schwarze2014-03-235-47/+17
|
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-232-0/+137
| | | | | | functions used for multiple languages (mdoc, man, roff), for example mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary functions. Split the auxiliaries out into their own file and header.
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-2334-126/+88
| | | | | | | functions used for multiple languages (mdoc, man, roff), for example mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary functions. Split the auxiliaries out into their own file and header. While here, do some #include cleanup.
* Remove currently unimplemented macros from the lists of used-definedIngo Schwarze2014-03-201-14/+16
| | | | | | | macros to be cleared during .Dd and .TH because clearing them at that point defeats the purpose of backup implementations provided in the manual page itself, some of which _do_ work with mandoc(1). While here, add the new .%C macro to the list to be cleared.
* Register pure .so pages as mlinks, not as mpages.Ingo Schwarze2014-03-191-19/+67
| | | | | | | This doesn't affect /usr/share/man, but improves /usr/X11R6/man: * Eliminates multiple apropos(1) output for such pages. * Reduces X11R6 database size from 450 kB to 240 kB (-47%). * Reduces X11R6 database build time from 1.68s to 1.00s (-40%).
* Without the MPARSE_SO option, if the file contains nothing but aIngo Schwarze2014-03-196-7/+24
| | | | | | single .so request, do not read the file pointed to, but instead let mparse_result() provide the file name pointed to as a return value. To be used by makewhatis(8) in the future.
* cope with mparse_alloc() interface changeIngo Schwarze2014-03-192-2/+2
|
* Generalize the mparse_alloc() and roff_alloc() functions by givingIngo Schwarze2014-03-196-52/+44
| | | | | | | | them an "options" argument, replacing the existing "inttype" and "quick" arguments, preparing for a future MPARSE_SO option. Store this argument in struct mparse and struct roff, replacing the existing "inttype", "parsetype", and "quick" members. No functional change except one tiny cosmetic fix in roff_TH().
* Allow checking that databases are up to date even when you have no writeIngo Schwarze2014-03-181-20/+94
| | | | | | permission on the databases, as requested by espie@ quite some time ago. But make sure to not slow database generation down when you do have write permission, and to not delay error reporting in -Q mode.
* in apropos(1) output, sort names and avoid multiple section numbersIngo Schwarze2014-03-171-6/+54

* Sync to OpenBSD:Ingo Schwarze2014-03-171-55/+151
| | | | | | | | * do not talk about shell globbing * describe logical operations * improve examples * add HISTORY * some wording improvements for clarity
* minor sync to OpenBSDIngo Schwarze2014-03-171-4/+26
|
* sync to OpenBSD: .ft is a roff(7) request, not a man(7) macro,Ingo Schwarze2014-03-172-6/+28
| | | | and it is not even used frequently in man(7)
* In -Tutf8 mode, make sure that hyphens get counted against the output lineIngo Schwarze2014-03-131-6/+7
| | | | | | | length even when they are breakable. Before this, a line containing N breakable hyphens could get up to N characters wider than the right margin in -Tutf8 output mode. Issue reported by tedu@ on <bugs at OpenBSD>.
* new bug report from wiz@ regarding Tcl*(3)Ingo Schwarze2014-03-081-0/+10
|
* In .nf mode, use the MAN_LINE flag to detect input line breaksIngo Schwarze2014-03-081-1/+1
| | | | | | instead of the man_node line member. This is required to preserve line breaks contained in user-defined macros called in .nf mode. Found in a code audit triggered by fixing a similar issue in .TP.
* To find out whether .TP head arguments are same-line or next-line arguments,Ingo Schwarze2014-03-083-11/+24
| | | | | | | | use the MAN_LINE flag instead of the man_node line member. This is required such that user-defined macros wrapping .TP work correctly. Issue found by Havard Eidnes in Tcl_NewStringObj(3), reported via the NetBSD bug tracking system and Thomas Klausner <wiz at NetBSD>.
* Improve .if/.ie condition handling.Ingo Schwarze2014-03-082-94/+156
| | | | | | | | | | | | | | * Support string comparisons. * Support negation not only for numerical, but for all conditions. * Switch the `o' condition from false to true. * Handle the `c', `d', and `r' conditions as false for now. * Use int for boolean data instead of rolling our own "enum roffrule"; needed such that we can use the standard ! and == operators. Havard Eidnes reported via the NetBSD bug tracking system that some Tcl*(3) manuals need this, and Thomas Klausner <wiz at NetBSD> forwarded the report to me. This doesn't make the crazy Tcl*(3) macrology maze happy yet, but brings us a bit closer.
* In roff_cond_sub(), make sure that the incorrect input sequence `\\}',Ingo Schwarze2014-03-071-11/+12
| | | | | | | when found on a macro line, does not close a conditional block. The companion function roff_cond_text() already did this correctly, but make the code more readable without functional change. While here, report the correct column number in related error messages.
* Even on macro lines, \} must not cause whitespace.Ingo Schwarze2014-03-071-14/+10
|
* Three bugfixes related to the closing of conditional blocks:Ingo Schwarze2014-03-071-25/+12
| | | | | | | | | | 1. Handle more than one `\}' on macro lines, as it was already done for text lines. 2. Do not treat `\}' as a macro invocation after a dot at the beginning of a line. That allows more than one `\}' to work on lines starting with `.\}'. It also simplifies the code. 3. Do not complain about characters following `\}'. Those are not lost, but handled normally both on text and macro lines.
* In -Tutf8 mode, mandoc_char(7) named accent character escape sequencesIngo Schwarze2014-03-051-11/+11
| | | | | | | | | | | | | | have to render as non-combining accents; if you want combining accents, you have to explicitly specify them using the Unicode character numbers for combining accents, or you can use character escape sequences for accented characters. This lets mandoc behave like groff. Additionally, both the Ossanna/Kernighan/Ritter troff manual and the GNU troff manual say that \' and \` are equivalent to \(aa and \(ga, respectively, so do the same for these. This mitigates issues with man(7) code autogenerated by texinfo2man(1), which mistranslates TeX ` and ' to \` and \' instead of \(oq and \(cq as reported by sthen@ and as analyzed by bentley@.
* - remove index.html, it is now part of the website repoIngo Schwarze2014-03-034-519/+30
| | | | | - install mandocdb, manpage, and apropos - and some general cleanup (e.g., installcgi is .PHONY)
* MANDOCERR_BADTAB needs checking, but .UR/.UE is doneIngo Schwarze2014-03-031-5/+11
|
* Move the regression suite to the attic.Ingo Schwarze2014-03-0386-1432/+0
| | | | | | | It has not been used or maintained for several years, and we won't start using it now. Devlopment regression testing is done in OpenBSD, and there is no value in maintaining two regression suites in parallel.
* After Werner Lemberg accepted and committed some updates to the manualIngo Schwarze2014-02-162-21/+33
| | | | | | page template contained in groff_mdoc(7), catch up with our own stuff. In particular, allow ERRORS in section 4 and DIAGNOSTICS in section 9. ok jmc@
* when indenting, extend the right margin accordingly, when needed;Ingo Schwarze2014-02-162-7/+13
| | | | fixes a crash reported by blambert@ and a few other, similar ones
* document .as and .ceIngo Schwarze2014-02-141-1/+13
|
* Parse and ignore the roff(7) .ce request (center some lines).Ingo Schwarze2014-02-142-5/+2
| | | | | | | | We even parse and ignore the .ad request (adjustment mode), and it doesn't make sense to more prominently warn about temporary than about permanent adjustment changes. Request found by naddy@ in xloadimage(1) and by juanfra@ in racket(1).
* Implement the roff(7) .as request (append to user-defined string).Ingo Schwarze2014-02-142-16/+15
| | | | | | | | | Missing feature found by jca@ in ratpoison(1). The ratpoison(1) manual still doesn't work because it uses .shift and .while, too (apparently, ratpoison is so complex that it needs a Turing-complete language to even format its manual :-). Written at Christchurch International Airport.
* Handle some predefined read-only number registers, e.g. .H and .V.Ingo Schwarze2014-02-142-5/+43
| | | | | | | | In particular, this improves handling of the pod2man(1) preamble; for examples of the effect, see some author names in perlthrtut(1). Missing feature reported by Andreas Voegele <mail at andreasvoegele dot com> more than two years ago. Written at Christchurch International Airport.

* Implement the \: (optional line break) escape sequence,Ingo Schwarze2014-01-227-19/+48
| | | | | | | documented in the Ossanna-Kernighan-Ritter troff manual and also supported by groff. Missing feature reported by Steffen Nurpmeso <sdaoden at gmail dot com>.
* Treat the line after .Cd as a single argument.Ingo Schwarze2014-01-211-1/+1
| | | | | This doesn't hurt normal manual display and makes the mandocdb(8) database more useful.
* Keep words after .Ic together in a single argument.Ingo Schwarze2014-01-201-1/+1
| | | | | This doesn't hurt normal manual display and makes the mandocdb(8) database more useful.
* Change markup of some fixed strings from .Ar to .Cm.Ingo Schwarze2014-01-201-31/+31
