* Remove a2roffdeco() and mandoc_special() functions and replace them withKristaps Dzonsons2011-04-091-237/+0
| | | | | | | | | | | | | | | | | | a public (mandoc.h) function mandoc_escape(), which merges the functionality of both prior functions. Reason: code duplication. The a2roffdeco() and mandoc_special() functions were pretty much the same thing and both quite complex. This allows one function to receive improvements in (e.g.) subexpression handling and performance, instead of having to replicate functionality. As such, the mandoc_escape() function already handles a superset of the escapes handled in previous versions and has improvements in performance (using strcspn(), for example) and reliable handling of subexpressions. This code Works For Me, but may need work to catch any regressions. Since the benefits are great (leaner code, simpler API), I'd rather have it in-tree than floating as a patch.
* Move mandoc_{realloc,malloc,calloc} out of libmandoc.h and into mandoc.hKristaps Dzonsons2011-03-171-1/+1
| | | | | | | | so that everybody can use them. This follows the convention of libXXXX.h being internal to a library and XXXX.h being the external interface. Not only does this allow the removal of lots of redundant NULL-checking code, it also sets the tone for adding new mandoc-global routines.

* Implement the \N'number' (numbered character) roff escape sequence.Ingo Schwarze2011-01-301-0/+44
| | | | | | | Don't use it in new manuals, it is inherently non-portable, but we need it for backward-compatibility with existing manuals, for example in Xenocara driver pages. ok kristaps@ jmc@ and tested by Matthieu Herrb (matthieu at openbsd dot org)
* correct horizontal spacing of data cellsIngo Schwarze2011-01-251-2/+2

* Add support for "^" vertical spanners. Unlike GNU tbl, raiseKristaps Dzonsons2011-01-111-0/+2
| | | | | | | error-class messages when data is being ignored by specifying it in "^" cells (either as-is or in blocks). Also note again that horizontal spanners aren't really supported...
* Clarify what members may be NULL or not in calculating widths. MakeKristaps Dzonsons2011-01-101-10/+13
| | | | | sure signedness is correct. Verify that layouts MUST exit for data cells.
* First, make extra data cells be thrown away. This makes "dp->layout"Kristaps Dzonsons2011-01-101-2/+1
| | | | | | | | | | | | always hold, which cleans up the table stuff a bit. Second, set a "spans" value per data cell consisting of the number of skipped TBL_CELL_SPAN layout cells. Third, make tbl_term.c understand how to skip over spanned sections when iterating over the header queue. What remains is to calculate the widths of spanned cells.

* Stuff tbl_calc() into out.c so that it can be shared by all output modesKristaps Dzonsons2011-01-051-0/+202
| | | | | | | | | | | | | | | | (isn't now, but will need to be, used by -T[x]html also). Necessitated a lot of churn in getting tbl_calc* code out of tbl_term.c and into out.c, including renaming some structures and so on. The abstraction is in having a pointer to a wrapper function for calculating string widths. The char devices use term_strlen and term_len; the others will probably just use strlen(). While at it, remove some superfluous assertions in the tbl code. This allows all tbl manuals to clear. Lastly, set the right-margin to be the maximum margin for each table span. This allows big, complicated tbl-pages like terminfo to be displayed. They're ugly, but they work.
* Remove overstrike `\o'. This isn't the best solution because we reallyKristaps Dzonsons2010-08-291-0/+2

* Handle nested, recursive mathematical subexpressions. This isKristaps Dzonsons2010-08-241-0/+20
| | | | | definitely not general, but it's good enough for pod2man definitions (after I clean up the roff, which will be addressed in later fixes).

* Stripping out of `\w' groff escape. Yet another for pod2man...Kristaps Dzonsons2010-08-241-0/+6

* Strip out the `\z' escape. This is the first recursive sequence,Kristaps Dzonsons2010-08-241-1/+10

* Add \v and \h to ignored escapes. These are in the category of \s.Kristaps Dzonsons2010-08-161-7/+10
| | | | | | Also made sign-less \s-style escapes be ok (this is technically against what's in the groff.7 manual, but seems pretty widespread). Noted by Thomas Jeunet as uglifying the gcc.1 manual.

* Accomodate for groff's crappy behaviour wherein an unrecognisedKristaps Dzonsons2010-07-211-1/+1
| | | | | | | | | | | | | single-character escape (and ONLY this type of escape) will map back into itself: "If a backslash is followed by a character that does not constitute a defined escape sequence the backslash is silently ignored and the character maps to itself." (From groff.7.) Found by Jason McIntyre.
* Double-up DECO_RESERVED switch branch for colours.Kristaps Dzonsons2010-07-191-15/+5

* Properly discard \m colour escapes. Noted by J.C. Roberts.Kristaps Dzonsons2010-07-181-0/+16

* Throw out a2roffdeco() in out.c for a readable version. The prior oneKristaps Dzonsons2010-07-181-179/+90
| | | | | | | | | | | | | was completely unmaintainable. The new one is both readable and quite similar to mandoc_special(), which in future versions will easily allow throwing-away of unsupported escapes (such as \m). It's also a fair bit smaller. DECO_SIZE has been removed: this crap, like colours, will not be supported. mandoc_special() also has #if 0'd switch branches for ALL groff.7 escapes and some lint fixes.
* Remove "pt" from struct roffsu, as CSS (the only reason it was there) isKristaps Dzonsons2010-06-251-2/+0
