| | | | | | | | | | delayed: It must either succeed right away or fail outright. As noticed by Kristaps, neglecting to fail properly when required could make invalid input screw up the syntax tree and ultimately trigger assertions in other, unrelated parts of the program. This fix tested by and OK by kristaps@. While here, comment the rather tricky function rew_dohalt(). This function will probably need more tweaks later on.

* fix a typo in the function declaration;Ingo Schwarze2010-06-291-1/+1
| | | | | seems like gcc3 didn't catch it :-( thanks to thib@ and kristaps@ for reporting
* 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@

| | | | | | | | | | | | | | | | | | | | | | | | | 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@

| | | | | | spacing, which is for mdoc.7/man.7 anyway). Also document -Opage=xxx and push the per-output options into the output subsections. Makes the manual shorter and more readable.

| | | | | | functional changes beyond the getsubopt() parse in term_ps.c. If you want to test this (it only does -Opaper=a4 and -Opaper=letter; adding more is trivial), make sure you specify (e.g.) -sPAPERSIZE=a4 to gs(1).
* Give -Tps better PostScript hinting. Note that we're using Adobe-3.0Kristaps Dzonsons2010-06-293-28/+73

* This enables variable glyph-width output. The checkin will be followedKristaps Dzonsons2010-06-282-26/+27
| | | | | | by a [functionless] clean-up in term_ps.c, but this makes the appropriate changes to "enable" initial proportional-width functionality in term.c and fixes some areas of term_ps.c that were causing errors.

* minor .Bk fixes:Ingo Schwarze2010-06-272-6/+16
| | | | | | | | * do not print invalid arguments verbatim (no groffs prints them, either) * do not trigger TERMP_PREKEEP twice * do not die from invlid arguments (groff won't die, either) * continue to ignore even valid arguments (just like groff) ok kristaps@ on the previous version, before removing my last bug ;)

* Following clue-stick applied by schwarze@, back out const-ness of regsetKristaps Dzonsons2010-06-2711-23/+38
| | | | | | | | | passed in to libmdoc and libman. Fix mdoc.3 and man.3 EXAMPLE sections to include regset. Add MDOC_SYNPRETTY flag cueing front-end to nicely format certain values as if SEC_SYNOPSIS were the current section.
* Downstream maintainers: this removes UGLY! I don't want divergingKristaps Dzonsons2010-06-2716-121/+111
| | | | | | | | | 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.

* First step of adding register support. This is inspired by a significantKristaps Dzonsons2010-06-268-13/+162
| | | | | | patch by schwarze@. This commit adds support to libroff parsing `nr' into register set defined in regs.h. This will propogate into libmdoc and libman in later commits.

* Initial chunks for variable-width fonts. Pushes all width calculationsKristaps Dzonsons2010-06-256-85/+133
| | | | | | | | in mdoc_term.c and man_term.c down into term.c. This is still not implemented in term.c, although stubs for width calculations are in place. From now on, offset, rmargin, and other layout variables are abstract screen widths. They will resolve to the the familiar values for -Tascii but -Tps will eventually use points instead of chars.

* Allow -width for lists to be cached in mdoc_bl. This requires someKristaps Dzonsons2010-06-134-52/+67
| | | | | | trickery because widths may be on-the-fly recalculated. I don't like how these are split between mdoc_action.c and mdoc_validate.c, but for the time being, it'll do.

* Cached `Bl -offset' into mdoc_bl. Removed erroneous "-offset defaultsKristaps Dzonsons2010-06-126-65/+46

* Reverted to mdoc_term.c 1.149 (`It' does not inherit `Bl's cache,Kristaps Dzonsons2010-06-121-7/+10

* Moved `Bl -compact' into cached data. This allowed the removal ofKristaps Dzonsons2010-06-124-30/+29

| | | | | | | sure where this came about. Added regression tests to convince myself that this is so. Also consolidated COMPATIBILITY notes regarding `Bd'. Added COMPATIBILITY note to the effect that old groff pukes on `Bd -compact -ragged' (regression test will fail on old groff).
* Cache all of `Bd's resolved arguments into mdoc_bd, which is stashed inKristaps Dzonsons2010-06-126-56/+120
| | | | | | the "data" union in mdoc_node. Allows me to remove some ugly loops in the front-end and duplicate tests in mdoc_action.c. Add a regression test to make sure we're not doing anything bad (more to come).
* Added enum mdoc_disp (similar to enum mdoc_list). Display types are nowKristaps Dzonsons2010-06-128-87/+77
| | | | | | | | | | | only calculated once in mdoc_validate.c. Noted that `Bd -file xxx' is not supported: it now raises a fatal warning. This is noted in mdoc.7. Empty `Bd' now defaults to LIST_ragged, which is not quite what groff does, but close enough (gross just throws away the `Bd' and gets upset when it encounters an `Ed').

| | | | | | TERMFONT_BOLD (Courier-Bold) and TERMFONT_UNDER (Courier-Oblique). It doesn't look half bad. This accomplished through tricksy juggling of the one-char back-buffer.
* Delay opening a word state until a character is ready to be output.Kristaps Dzonsons2010-06-111-20/+41
| | | | | This paves the way for closing/reopening scope in the event that a font changes.
* Teach -Tps to ignore backspace-encoding by using a one-char buffer and aKristaps Dzonsons2010-06-113-5/+32
