* Considerably simplify block rewind rules; no functional change intended.Ingo Schwarze2010-06-291-206/+69
| | | | | | | | | | * Let rew_alt() always succeed, obsoleting tons of case statements. * Merge rew_dobreak() into rew_dohalt(). * Encode all rewinding cases uniformly in terms of "enum rew". Required because i'm too dumb to get SYNOPSIS .Nm rewinding right without cleaning this up first. "get it in" kristaps@
* Support for badly nested blocks, written around the time ofIngo Schwarze2010-06-291-72/+194
| | | | | | | | | | | | | | | | | | | | | | | | | the Rostock mandoc hackathon and tested and polished since, supporting constructs like: .Ao Bo Ac Bc (exp breaking exp) .Aq Bo eol Bc (imp breaking exp) .Ao Bq Ac eol (exp breaking imp) .Ao Bo So Bc Ac Sc (double break, inner before outer) .Ao Bo So Ac Bc Sc (double break, outer before inner) .Ao Bo Ac So Bc Sc (broken breaker) .Ao Bo So Bc Do Ac Sc Dc (broken double breaker) There are still two known issues which are tricky: 1) Breaking two identical explicit blocks (Ao Bo Bo Ac or Aq Bo Bo eol) fails outright, triggering a bogus syntax error. 2) Breaking a block by two identical explicit blocks (Ao Ao Bo Ac Ac Bc or Ao Ao Bq Ac Ac eol) still has a minor rendering error left: "<ao1 <ao2 [bo ac2> ac1> bc]>" should not have the final ">". We can fix these later in the tree, let's not grow this diff too large. "get it in" kristaps@
* Downstream maintainers: this removes UGLY! I don't want divergingKristaps Dzonsons2010-06-271-24/+15
| | | | | | | | | functionality and UGLY works quite well thanks to schwarze@'s careful attention. This also backs out function-prototype changes for struct regset, instead stuffing a pointer to the regset directly into struct mdoc/man/roff.

* Remove now-superfluous check on `Ta' context.Kristaps Dzonsons2010-05-311-20/+0
|
* Add ability to interpret initial free-form lines as part of a `BlKristaps Dzonsons2010-05-311-1/+11
| | | | | | | | -column' up until the first `It'. This is UGLY and should have all sorts of warnings, and will. On the one hand, it fits with groff's notion of tabs and tab-spaces. On the other hand, it's not really "free-form" text any more. Note that this does not yet accomodate for macros coming on these lines.
* `Ta' scope-checks need to be more specific (until implicit `It' handlingKristaps Dzonsons2010-05-311-1/+4
| | | | comes into play).
* Remove enum mdocargerr from phrase() (unused).Kristaps Dzonsons2010-05-311-22/+96
| | | | | | | | | | | | | | Add `Ta' macro, which is basically a NULL case everywhere but in mdoc_macro.c, where it closes out an existing `It' body scope and opens a new one, then continues parsing as in phrase() (TODO: merge these two?). Fix where scope-breaking was silently just dying instead of printing an error. Fix where trailing `Ta' or tab weren't creating a new MDOC_BODY context. We now support arbitrarily complex `It' contents for `Bl -column'.
* Migrate `Bl -column' phrases to be MDOC_BODY instead of MDOC_HEAD. ThisKristaps Dzonsons2010-05-301-13/+19
| | | | | | | | | | will make it easy for re-entrant parsing of `Ta' macros to fit in with standard closure rules. Added some more regressions for `Bl -column'. Note that one should fail, as documented in the TODO file. Recorded change of AST BNF in mdoc.3.
* Final word on lac/ac. Document flow as it relates to phrasing, as I'llKristaps Dzonsons2010-05-301-4/+17

* First in several iterative patches in getting complex -column listsKristaps Dzonsons2010-05-301-8/+12
| | | | | | | | supported (which works but is tricky enough that it should be broken down into digestable parts). This simply moves around the propogation of ARGS_PEND into one recognised by phrase(). Added a few regressions for simple -column lists.
* Commit of patch floated on discuss@ a few days ago: if an in_line scopeKristaps Dzonsons2010-05-291-11/+32
| | | | | | | | | | has not been opened and closing punctuation is encountered AND the macro is marked as accepting no-content (or `Li'), then open an empty scope. Added regression tests for `Fl' and `Li' testing this behaviour. Also, squeeze hyph0.in tests into the last characters of each line so that groff doesn't hyphenate and break the test.
* Fixed `Lb' to be in_line (reported by Ulrich Spoerlein).Kristaps Dzonsons2010-05-261-1/+1
| | | | | | | | | Added `Lb' documentation to mdoc.7. Removed harmless but superfluous pre_lb check (was just NULL entries). Added regressions for `Lb' (NOTE that these will only run on new groff, as old groff doesn't support `Lb' at all).
* Enable the unified error/warning enumeration in mandoc.h that'sKristaps Dzonsons2010-05-171-14/+18
| | | | | | | | | | | stringified in main.c. Allow `An' to handle an argument and child (with a warning). Allow `Rv' and `Ex' to work without a prior `Nm' as groff does (with a warning). Allow inconsistent column syntax to only raise a warning.
* Distinguish OPEN, MIDDLE and CLOSE delimiters (using an enum).Ingo Schwarze2010-05-151-10/+12
| | | | | | | Only OPEN are drawn before the beginning of a macro; this is new, before this, MIDDLE ('|') were drawn in front, too. Only CLOSE are pushed after the end of a macro (as before). ok kristaps@
* More EOS: append_delims() fitted with EOS detection, so ANY macro with ↵Kristaps Dzonsons2010-05-151-6/+21
| | | | | | appended delimiters will properly EOS. Fixed mandoc_eos() to accept sentence punctuation followed by close-delim buffers.
* More `Bl -column' dancing: It children also inherit in-phrase flags (noted ↵Kristaps Dzonsons2010-05-151-22/+14

* Block-implicit macros now up-propogate end-of-sentence spacing. NOTE: GROFF ↵Kristaps Dzonsons2010-05-141-0/+20

* Fixed bug in -Thtml -mdoc where `Lb' would line-break in LIBRARY section.Kristaps Dzonsons2010-05-131-12/+21
| | | | | Fixed assumption that parse-point == 1 equates to beginning of line (false if whitespace separates macro and control character). Fixed line-break for non-first-macro in several SYNOPSIS macros.
* Introduce ARGS_PEND for `It -column' end-of-line special casing.Kristaps Dzonsons2010-05-091-14/+44

* Re-adjusting UGLY tags.Kristaps Dzonsons2010-03-311-4/+2
| | | | | Fixed removed assignment of type. Removed superfluous checks of mdoc_argflags (from days when comments were a macro tag).
* Macro types enum-ated (enum mdoct) (for easier debugging in gdb of "tok" ↵Kristaps Dzonsons2010-03-311-15/+52
| | | | | | | values). Initial check-in of Ingo Schwarze's patch for Xo/Xc handling (in blocks ifdef'd "UGLY"). Put Oc-close-Op parts into UGLY ifdef blocks.

* Fixed segfault with accidentally-munged tree.Kristaps Dzonsons2010-03-291-10/+8

* Integrate Ingo Schwarze's patch for mdoc_iscdelim() (tri-state for opening ↵Kristaps Dzonsons2010-03-291-75/+107
| | | | | | | | | | | and closing macro punctuation). Modify blk_part_exp() to correctly handle leading punctuation before HEAD. Significantly clean up and document blk_part_exp(). Modify blk_part_imp() for to correctly handle leading punctuation before HEAD. Significantly clean up and document blk_part_imp(). Integrate Ingo Schwarze's patch for args() (using new mdoc_iscdelim() format). Documented bad `Ec' handling for later work in mdoc_term.c/mdoc_html.c.
* Made `Xr' compatible with groff calling conventions where arguments ↵Kristaps Dzonsons2010-02-171-2/+18
| | | | | | following the trailing section are implicitly `Ns'd. Based on a patch submitted by Ingo Schwarze.
* Fix in handling Vt in SYNOPSIS with trailing punctuation. Spotted by Joerg ↵Kristaps Dzonsons2010-01-301-1/+27

* Big check-in of compatibility layer. This should work on most major ↵Kristaps Dzonsons2010-01-011-0/+4

* `Fl' has each argument be in a separate scope (thanks Ingo Schwarze).Kristaps Dzonsons2010-01-011-0/+11
| | | | | Situation of `Fl [arg]* "" [arg]*' is fixed: empty arguments are ignored. Note that OpenBSD crashes when this happens. Situation of `Fl' is fixed wrt trailing whitespace.
* Added time.h to various files for FreeBSD compilation (thanks Ulrich Sporlein).Kristaps Dzonsons2009-10-261-0/+1
|
* Added `%U' to -mdoc (doesn't render in a nice way yet).Kristaps Dzonsons2009-10-241-0/+1
