* fix build when HAVE_MANPATH is set; patch from <bapt at FreeBSD>Ingo Schwarze2014-11-271-1/+1
|
* Ignore invalid directories in man.conf(5) and MANPATH, even if theirIngo Schwarze2014-11-181-15/+30
| | | | | | parent directories exist, but complain about invalid directories given on the command line. Intended to fix an oddity reported by sthen@.
* Improve build system and autodetection.Ingo Schwarze2014-08-161-1/+1
| | | | | | | | | * Make ./configure standalone, that's what people expect. * Let people write a ./configure.local from scratch, not edit existing files. * Autodetect wchar, sqlite3, and manpath and act accordingly. * Autodetect the need for -L/usr/local/lib and -lutil. * Get rid of config.h.p{re,ost}, let ./configure only write what's needed. * Let ./configure write a Makefile.local snippet, that's quite flexible.
* Get rid of HAVE_CONFIG_H, it is always defined; idea from libnbcompat.Ingo Schwarze2014-08-101-2/+2
| | | | | | 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.
* Audit malloc(3)/calloc(3)/realloc(3) usage.Ingo Schwarze2014-04-231-2/+2
| | | | | | | * Change eight reallocs to reallocarray to be safe from overflows. * Change one malloc to reallocarray to be safe from overflows. * Change one calloc to reallocarray, no zeroing needed. * Change the order of arguments of three callocs (aesthetical).
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-3/+2
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-231-1/+1
| | | | | | | 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.
* My audit of mandoc revealed one missing (unsigned char) castIngo Schwarze2013-11-211-1/+1
| | | | | in an isspace() argument containing arbitrary char data. Thanks to deraadt@ for triggering the audit.
* Some places used PATH_MAX from <limits.h>, some MAXPATHLEN from <sys/param.h>.Ingo Schwarze2013-06-051-5/+1
| | | | | | Consistently use the PATH_MAX since it is specified by POSIX, while MAXPATHLEN is not. In preparation for using this at a few more places.
* Sync to OpenBSD:Ingo Schwarze2013-05-291-2/+4
| | | | | | | | * Guard <sys/param.h> inclusion by #ifdef USE_MANPATH to make it more obvious why this isn't needed on OpenBSD. Noticed by deraadt@. * Resolve gratuitious whitespace differences: Blanks before tabs and on empty lines.
* Use size_t in manpath instead of int.Kristaps Dzonsons2012-06-081-5/+5
|
* Support leading, trailing and double colons in MANPATH to prepend,Kristaps Dzonsons2011-12-241-6/+45
| | | | | | | | append or insert the man.conf(5) default path; compatible with GNU manpath(1), implementation by kristaps@, heavily tweaked by schwarze@. Updates to MANPATH documentation applied to whatis.1, apropos.1, and catman.8 also.
* Remove stray warnx() left in the manpath.c code.Kristaps Dzonsons2011-12-131-1/+0
|
* Have manpath.c properly use manpath(1), that is, using -C and -m and so on.Kristaps Dzonsons2011-12-131-41/+52
| | | | | This also cleans up the code a little bit. While here, make some functions static that are only used within manpath.c.
* implement -C (alternative config file) for apropos(1) and mandocdb(8),Ingo Schwarze2011-12-121-5/+6
| | | | | including various tweaks to the whatis(8) manual; ok kristaps@
* Sync to OpenBSD, mostly gratuitous and whitespace differences,Ingo Schwarze2011-11-261-8/+9
| | | | | | | | | but a few serious things as well: * -M overrides MANPATH * -m prepends to the path * put back database close calls that got lost in mandocdb * missing sys/types.h in manpath.c, needed for size_t ok kristaps@
* Allow man.conf file to be assignable.Kristaps Dzonsons2011-11-241-3/+3
|
* Export the manpath_manconf() function, slightly reorderng manpath.c whileKristaps Dzonsons2011-11-241-13/+20
| | | | | doing so. This will be used by a jailed man.cgi, as the cache built by manup(8) creates a man.conf for it to use.
* Support for Open/NetBSD's /etc/man.conf and others' manpath(1).Kristaps Dzonsons2011-11-231-0/+167
Most of this code (except the manpath part) written by schwarze@. This isn't hooked into anything yet.
