* Integrate a moderately-patched version of schwarze@'s support for multipleKristaps Dzonsons2011-11-204-81/+186
| | | | | | | | | | | directories containing mandocdb(8) databases. Some changes follow: (1) don't support -M yet; (2) fall back to cwd if no prior manpath has been specified; (3) resolve manpages using realpath() to prevent consecutive chdir()'s over relative paths; (4) note where further error-reporting is required; (5) fix leaking memory on exit in several cases.
* Fix white-space in apropos_db.c to make merging cleaner.Kristaps Dzonsons2011-11-201-39/+39

* Merge schwarze@'s work for 64-bit types. This is based on a tweaked patchKristaps Dzonsons2011-11-204-56/+114
| | | | | | | submitted to tech@ on 16/11/2011, 01:39. It has been updated to account for the logical-operator functions and to avoid keeping a live pointer into the DBT value, which is not guaranteed to be consistent across calls into the bdb library.
* Improve misleading comment:Ingo Schwarze2011-11-191-1/+5
| | | | | | | | * Not sure there were any text nodes, might have been other stuff instead. * Not sure it was just one node, maybe several were deleted. * No problem if some nodes were deleted, as long as some valid ones are left. * We do not leave early, but after cleaning out all the crap. * We are not "bailing", but we consider the block valid after cleanup.
* Fix condition. Not enough tea.Joerg Sonnenberger2011-11-181-1/+1

* Convert an assert into an explicit check. man_unscope can be triggeredJoerg Sonnenberger2011-11-181-1/+2

* Bail out explicitly on invalid .Rs content like:Joerg Sonnenberger2011-11-181-0/+4

* Add lots of information about special characters that's actually neededIngo Schwarze2011-11-141-40/+175
| | | | | | in practice, and discourage using fancy characters in manuals. Text about "Dashes and Hyphens" by jmc@. Feedback and ok jmc@, grudgingly ok kristaps@.
* Have exprcomp() accept a string instead of an array-pointer. Also, collapseKristaps Dzonsons2011-11-143-9/+36
| | | | | the arguments in apropos(1) into a single string passed to exprcomp(). Ok schwarze@.
* Make the man(7) page footer the same as in groff.Ingo Schwarze2011-11-131-9/+16

* typo: overful -> overfull; thanks to jmc@Ingo Schwarze2011-11-131-1/+1
|
* Make the default left text margin configurable from the command line,Ingo Schwarze2011-11-135-23/+38
| | | | | | | just like the default right margin already is. This may be useful for people with expensive screen real estate. Besides, it helps automated man(7) to mdoc(7) output comparisons to validate -Tman output. ok kristaps@ on an earlier version
* Rewrite the expression parser for a more concise syntax:Ingo Schwarze2011-11-133-65/+54
| | | | | | | | | | | | | apropos [search_type[,...]=]substring apropos search_type[,...][,i]~regex ... and expression evaluation must take the search type into account. This allows to: * drop the global -I option and * drop the enum match, just using a boolean int. "go ahead" kristaps@
* Inventing new keywords for mostly the same thing when a well-establishedIngo Schwarze2011-11-136-69/+74
| | | | | | | | | | set of keywords already exists is a bad idea, so reuse the mdoc(7) macro names as apropos(1) search types. This is a gain in brevity as well. Some time ago, kristaps@ agreed in principle. The search type bit field constants are used by both mandocdb(8) and apropos(1) and should better stay in sync, so give them their own header file.
* Less misleading file names; ok kristaps@.Ingo Schwarze2011-11-135-9/+9
|
* another detail to implement;Ingo Schwarze2011-11-131-0/+3
| | | | long live the tricky exceptions!
* Fix two crashes that occur when walking very large (i.e. real-world) trees:Ingo Schwarze2011-11-131-4/+4
| | | | | | 1) Avoid excessive, needless recursion, lest you overflow the stack; 2) Close all dir file descriptors, lest you run out of descriptors. ok kristaps@
* Use proper infix expressions and provide a default. (Exact match.)Kristaps Dzonsons2011-11-091-11/+24

* Make apropos's lookup use a find(1)-like expression. I'll write more onKristaps Dzonsons2011-11-094-84/+146
| | | | | | | | | | this when it completes; this is to keep it in-tree. Right now this uses prefix notation. Ignore it. I'll make this into infix notation real soon. The goal of this (exprcomp and exprexec) is to have arbitrary logical expressions.
* Change getopt() to be more like schwarze@'s suggestions.Kristaps Dzonsons2011-11-092-43/+24
|
* Split apropos.c into db.c and apropos.h with simpler code (re-written, butKristaps Dzonsons2011-11-095-551/+860
| | | | | | | | | inspired by apropos.c and mandoc-tools' mandoc-cgi.c). This uses UTF-8 right now for its re-writing, but will soon accomodate for the regular suspects (this is a rather simple matter). I also introduce man.cgi (cgi.c), which is a standalone CGI that replaces mandoc-tools' mandoc.cgi. Right now it's just a framework.
* Const-ify some mchars arguments. I think these are non-const for historicalKristaps Dzonsons2011-11-083-10/+13
| | | | dumbness on my part.
* When the HEAD scope of .TP is broken by another block macro,Ingo Schwarze2011-11-077-44/+51
| | | | | | | | do not abort with a FATAL error, but report a report a WARNING, remove the broken .TP from the syntax tree, and prod on. Reported repeatedly by ports people, at least by brad@ and jeremy@. Also fixes rendition(4) in Xenocara. ok kristaps@
* Accomodate for \f(Cx formatting. Noted by Andreas Vogele, thanks!Kristaps Dzonsons2011-11-062-1/+10
|
* When .TH sets no data, leave the date field in the page footer blank,Ingo Schwarze2011-11-031-3/+5
| | | | | | do not use the current date. This removes a gratuitous output difference with respect to groff. ok kristaps@
* Correct .Eo spacing:Ingo Schwarze2011-11-032-2/+10
| | | | | no space between the delimiters and the enclosed text. The mdoc_html.c part was added by kristaps; ok kristaps@.
* Clean up the description of .Dt:Ingo Schwarze2011-11-011-36/+14
| | | | | | | | | | | - Volume and arch are both optional and not alternatives. - Zap verbiage about what's obvious from the synopsis. - For fixed argument strings, use .Cm, not .Ar. Using lots of input from jmc@. Also, state that the list of valid architectures varies by OS. If a downstream distribution wants to provide a specific list, maintaining a local patch is the way to go.
* Implement missing enclosures (Ao Do Qo Qq So Bro Brq)Ingo Schwarze2011-10-241-23/+23
| | | | | | | and enclosure-like in-line macros (Ad Cd Dv Er Ev Li Ms Tn). The .No macro works without explicit implementation. ok kristaps@
* Handle infinite recursion the same way as groff:Ingo Schwarze2011-10-241-8/+12
| | | | | | | When string expansion exceeds the recursion limit, drop the whole input line, instead of leaving just the string unexpanded. ok kristaps@
* Handle \N numbered character escapes the same way as groff:Ingo Schwarze2011-10-241-6/+22
| | | | | | | | | | | | | If \N is followed by a digit, ignore \N and the digit. If \N is followed by a non-digit, the next non-digit ends the character number; the two delimiters need not match. Kristaps calls that "gross, but not our fault". For now, i'm fixing \N only. Other escapes taking numeric arguments may or may not need similar handling, but \N is by far the most important for practical purposes. ok kristaps@
* Implement the missing text production macros (Bsx Bx Dx Fx Nx Ox Ux Bt Ud).Ingo Schwarze2011-10-201-18/+53
| | | | | Some macros work without explicit implementation (At Db Os St). ok kristaps@
* Fix mandoc_escape() function argument names. From a fix by AbhinavKristaps Dzonsons2011-10-181-3/+3
| | | | Upadhyay, thanks!
* Sync to groff, and add tier I and II NetBSD architectures.Ingo Schwarze2011-10-162-0/+55
| | | | ok kristaps@
* Remove a bunch of useless assignments,Ingo Schwarze2011-10-166-19/+15
| | | | | | | 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 Schwarze2011-10-092-72/+34
| | | | | if desired, they can be overridden in the CSS file. Suggested by kristaps@, and i always like to simplify code.
* A bit more precision and nicer wording in the descriptionsIngo Schwarze2011-10-091-7/+20
| | | | of -Ofragment and -Tman; using input from jmc@ and kristaps@.
* Make apropos results-gathering able to error out and clean up beforeKristaps Dzonsons2011-10-091-14/+16
| | | | making the utility exit non-zero.
* Remove some unnecessary variables and note that mchars_alloc never returnsKristaps Dzonsons2011-10-091-25/+7
| | | | NULL.
* Use a binary tree (for now, unbalanced) for deduping the records in theKristaps Dzonsons2011-10-091-5/+31
| | | | | | results array. This is much faster than the previous method, a linear search, at a small cost. Note that array offsets are used instead of storing the res pointer because we may realloc the results vector.
* The documented flags in mandocdb (-u, -d) were switched. Fix this.Kristaps Dzonsons2011-10-091-2/+2
