* When opening mandoc.db fails, tell the user in which directory.Ingo Schwarze2014-12-061-1/+3
| | | | Improving an unhelpful error message reported by millert@.
* implement help(1)Ingo Schwarze2014-12-051-8/+21
|
* Improve parsing of function names.Ingo Schwarze2014-12-051-24/+27
| | | | This gets rid of the last bogus entries in base and Xenocara.
* Do not misinterpret function arguments as function names;Ingo Schwarze2014-12-051-0/+3
| | | | improves semantic analysis of more than 300 manuals.
* Render text before, not after accumulating flag bits, such that flagsIngo Schwarze2014-12-051-116/+107
| | | | | for different representations of the same string end up in the same database entry. Improves name classification for 500 manuals.
* When finding a .so link after the page was already processed,Ingo Schwarze2014-12-041-3/+16
| | | | | do not clobber the existing names flags; instead, OR the additional flags into them.
* correctly store .Dt and .TH information in the names tableIngo Schwarze2014-12-041-10/+27
|
* in the SYNOPSIS, add .Fo and first .Fn arguments to the names tableIngo Schwarze2014-12-041-1/+16
|
* In the SYNOPSIS, if .Nm occurs without argument, give the first .NmIngo Schwarze2014-12-041-24/+47
| | | | that occurred in the document a NAME_SYN entry in the names table.
* fix handling of roff requests having a default scale other than "n",Ingo Schwarze2014-12-043-3/+3
| | | | | in particular .sp which uses "v", when the scale is not specified; cures groff-mandoc differences in about a dozen Xenocara manuals
* Ignore macros that never produce any text when deciding whetherIngo Schwarze2014-12-041-12/+23
| | | | | | vertical whitespace is needed before a section or subsection. Cures groff-mandoc differences in more than 300 manuals, mostly Xenocara, some curses, a few GNU.
* delete five entries that were already fixedIngo Schwarze2014-12-031-23/+0
|
* Switch the default output mode from -Tascii to -Tlocale.Ingo Schwarze2014-12-022-6/+8
| | | | | | | | This doesn't change anything unless LC_CTYPE is set, but it helps when running with LC_TYPE=something.UTF-8. OK tedu@ and earlier positive feedback from: bentley@ deraadt@ naddy@ stsp@ uqs@freebsd wiz@netbsd
* note to self to not forget about groffIngo Schwarze2014-12-021-0/+6
|
* we really need .taIngo Schwarze2014-12-021-1/+2
|
* Fix the implementation and documentation of \c (continue text input line).Ingo Schwarze2014-12-0210-25/+21
| | | | | In particular, make it work in no-fill mode, too. Reminded by Carsten dot Kunze at arcor dot de (Heirloom roff).
* developer documentation regarding header filesIngo Schwarze2014-12-012-0/+513
|
* header cleanup:Ingo Schwarze2014-12-0115-32/+41
| | | | | | * add missing forward declarations * remove needless header inclusions * some style unification
* The header libmandoc.h is part of the internal parser interface,Ingo Schwarze2014-12-011-1/+0
| | | | | | but html.c is not part of the parser at all, so it cannot include that header, and actually, it doesn't need it. Found while auditing includes after Theo's recent *.h commit.
* The file read.c is part of the parser, so it cannot include main.h,Ingo Schwarze2014-12-012-4/+3
| | | | | | | which is not part of the parser. Besides, the parser *does* modify the input buffer, so marking it "const" in the mparse_readmem() interface is an outright lie. Fix all this by killing the const, the UNCONST, and the bogus inclusion.
* remove unneccessary inclusion protection; patch from deraadt@Ingo Schwarze2014-12-0114-56/+0
|
* typo; Svyatoslav Mishyn <juef at openmailbox dot org> (Crux Linux)Ingo Schwarze2014-11-301-1/+1
|
* delete three standard abbreviations that areIngo Schwarze2014-11-302-15/+2
| | | | | | * no longer used in OpenBSD * not used in any of NetBSD, FreeBSD, or DragonFly * not supported by groff
* Multiple fixes with respect to .Pf:Ingo Schwarze2014-11-308-10/+33
| | | | | | | * 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.
* warn about attempts to call non-callable macros;Ingo Schwarze2014-11-304-8/+25
| | | | inspired by a similar warning in the groff_mdoc(7) macros
* Reduce code duplication by reusing the same argument parserIngo Schwarze2014-11-291-18/+20
| | | | | for in_line_eoln() macros and .Bl -column phrases. No functional change.
* Provide a helper function macro_or_word() and use it to prune theIngo Schwarze2014-11-293-128/+68
| | | | | | | | | | same chunk of argument parsing code out of five of the eight callback functions. The other three have too much special handling to participate. As a bonus, let lookup() and mdoc_args() deal with line macros and retire the lookup_raw() helper and the mdoc_zargs() internal interface function. No functional change, minus 40 lines of code.
* Fold the loop around mdoc_argv() into the function itself,Ingo Schwarze2014-11-283-124/+82
| | | | | | it was the same in all four cases. As a bonus, get rid of one enum type that was used for internal communication. No functional change, minus 40 lines of code.
* AT&T is unlikely to release an new version of Research UNIX any time soon.Ingo Schwarze2014-11-284-49/+18
| | | | | So, it's pointless to make adding version strings easy for downstream. One source file less to maintain.
* Retire support for CSRG supplementary document titles. These areIngo Schwarze2014-11-286-120/+5
| | | | | long obsolete and were never written in mdoc(7) in the first place. Removes 100 lines from source files.
* Drop useless architecture table. Validating architecture namesIngo Schwarze2014-11-288-181/+9
| | | | | | is a job for makewhatis(8)/mandoc.db(5), not for the parser. Removes 150 lines from source files and 4k (1%) from the binary. Bloat found by deraadt@.
* kill a pointless assertIngo Schwarze2014-11-281-3/+0
|
* mop up an #ifdef turd deraadt@ stepped intoIngo Schwarze2014-11-281-8/+2
|
* Be more careful about meta->name. For weird input, it can be NULL.Ingo Schwarze2014-11-281-6/+10
| | | | Fixing a NULL access jsg@ found with afl.
* Simplify by making the eqn and tbl steering functions void;Ingo Schwarze2014-11-284-41/+24
| | | | no functional change, minus 15 lines of code.
* Simplify by making many functions in the man(7) parser void,Ingo Schwarze2014-11-286-284/+181
| | | | and some cleanup; no functional change, minus 70 lines.
* Simplify by making the mdoc parser callbacks void, and some cleanup;Ingo Schwarze2014-11-283-215/+137
| | | | no functional change, minus 50 lines of code.
* Simplify the code by making various mdoc parser helper functions void.Ingo Schwarze2014-11-284-431/+268
| | | | No functional change, minus 130 lines of code.
* Simplify code by making mdoc validation handlers void.Ingo Schwarze2014-11-284-413/+284
| | | | No functional change, minus 90 lines of code.
* Downgrade .Bd -file from FATAL to ERROR.Ingo Schwarze2014-11-274-14/+14
| | | | | Since this was the last remaining FATAL error in this area, this change will allow major simplifications in the mdoc(7) parser.
* Multiple fixes with respect to .Eo:Ingo Schwarze2014-11-274-22/+58
| | | | | | | | 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 Schwarze2014-11-275-39/+33
| | | | | and not trigger an assertion when there is more than one argument; the latter found by jsg@ with afl.
* Make makewhatis(8) understand .so links to .gz pages.Ingo Schwarze2014-11-273-27/+25
| | | | | | | | Drop the FORM_GZ annotation in the mpages table; it is conceptually wrong because it ought to be in the mlinks table: An uncompressed .so link file can point to a compressed manual page file and vice versa. Besides, it is no longer needed because mparse_open() handles it all. Sprinkle some KNF while here.
* fix build when HAVE_MANPATH is set; patch from <bapt at FreeBSD>Ingo Schwarze2014-11-271-1/+1
|
* Let mparse_readfd() use mparse_open() and mparse_wait()Ingo Schwarze2014-11-262-28/+59
| | | | | | | | and let mparse_open() fall back to .gz files such that .so works even when the target is zipped, requested by and in part using ideas from <bapt at FreeBSD>. While here, make sure files are readable before forking, both for efficiency and for better error reporting.
* Simplify the mparse_open()/mparse_wait() interface.Ingo Schwarze2014-11-266-32/+20
| | | | | Don't bother the user with the PID of the child process, store it inside the opaque mparse handle.
* remove an unreachable warning about .Sm argumentsIngo Schwarze2014-11-261-2/+0
|
* The .Sm macro accepts at most one argument;Ingo Schwarze2014-11-261-1/+1
| | | | fixing an assertion failure found by jsg@ with afl.
* Make the code sipler and more robust by always assigning a valueIngo Schwarze2014-11-261-11/+5
| | | | to q.manpath and dropping the (incomplete) later NULL checks.
* Allow comma-separated options in tbl(7) tables.Ingo Schwarze2014-11-262-2/+3
| | | | | Provides better groff compatibility. From bentley@.
