* 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.
* Notes: this must be done later. \b in the input will cause havoc.Kristaps Dzonsons2010-06-282-0/+10

* Initial encoding of glyph widths. From /usr/X11R6/lib/X11/fonts/Type1.Kristaps Dzonsons2010-06-281-14/+341

* Tiny commit clarifying flushln() documentation as to what refers toKristaps Dzonsons2010-06-281-3/+4
| | | | | visual screen output and what's an array index (getting closer to variable-width fonting).
* 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.
* Remove "pt" from struct roffsu, as CSS (the only reason it was there) isKristaps Dzonsons2010-06-255-12/+9
| | | | | unclear about which units accept floats/integers, which leads me to assume that it handles either and rounds as appropriate.
* Allow OpenBSD's nroff to process mandoc.1 without puking on long `It'Kristaps Dzonsons2010-06-251-6/+10

* 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.

| | | | | | 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.
* Small optimisations in mdoc_action list processing. Cleanups making wayKristaps Dzonsons2010-06-131-37/+35

* Cached `Bl -offset' into mdoc_bl. Removed erroneous "-offset defaultsKristaps Dzonsons2010-06-126-65/+46
| | | | | to 6n if no value is specified" and added regression tests for `Bl' testing against the empty -offset argument.
* 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

* `Bl' is now using a struct instead of a single enum mdoc_list for itsKristaps Dzonsons2010-06-126-25/+31

* Removed stipulation that an empty `Bd -offset' will default to 6n. NotKristaps Dzonsons2010-06-127-33/+80
| | | | | | | 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').
* Add FreeBSD libraries (provided by Ulrich Spoerlein).Kristaps Dzonsons2010-06-111-0/+25

* Implement font-switching for PostScript. -Tps now supportsKristaps Dzonsons2010-06-112-61/+134
| | | | | | 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

* Allow open word contexts in -Tps to preserve whitespace, as whitespaceKristaps Dzonsons2010-06-101-3/+4
| | | | | apparently doesn't collapse in PostScript (surprise!). Makes output files much more compact.
* Fix a regression that crept in in man_term.c 1.73 and mdoc_term.c 1.144.Ingo Schwarze2010-06-102-5/+4
| | | | | | | | | | | | | | | | When the title line uses special characters, mandoc will segfault. Thus, first set up the character tables, then print the header, as we always did. Found in OpenBSD /usr/src/usr.sbin/bind/bin/check/named-checkconf.8. While here, set p->tabwidth in terminal_man() for symmetry with terminal_mdoc(), as suggested by millert@ (and already committed to OpenBSD earlier). Since 5 is the default, this is not strictly required, but it is certainly clearer and more robust. "looks fine" kristaps@
* Fix adding some minimal intelligence to conditional parser. See roff.7Kristaps Dzonsons2010-06-103-35/+131
| | | | | | | | | | for what's supported. This simplified the roff_cond() function quite nicely. From a bug report by uqs@. Added regression test based on bug-report example by uqs@. Also added ROFF_DEBUG to see what the hell the parser is actually doing. Obviously turned off by default.
* Make "sub" for conditionals run roffnode_cleanscope() before callingKristaps Dzonsons2010-06-091-1/+11
| | | | down to sub-arguments. From a bug report by Ulrich Spoerlein.
* Squash bug noted by Ulrich Spoerlein where "-" were being converted toKristaps Dzonsons2010-06-095-44/+65
| | | | | | | | | ASCII_HYPH, as per normal, but were screwing up mandoc_special(). Fixed by making mandoc_special() first check isspace() instead of ! isgraph(), then normalise its string as it passes out. This require de-constifying some validation routines not already de-constified (those in libman), but that's ok, because I'd like to be pushing actions into validation routines to save on space and redundant calculations.
* Forgot to increment into the nil terminator. And call va_end() whileKristaps Dzonsons2010-06-091-1/+3
| | | | we're at it.
* Have the standard manpage header and footer print on every page of -TpsKristaps Dzonsons2010-06-095-68/+153
| | | | | | | | | | | | | | | output. This is more tricky than you may think: we can't just call the header function out-of-state (i.e., before a flushln has occured) because we'd clobber our current state. Thus, we call at the beginning and dump the output into an auxiliary buffer. For the record, I don't think there's any other clean way to do this. The only other Way That Works is to copy-aside *all* termp state, zero it, and do the necessary headf/footf. This is just as complex, as memory needs to be alloc'd and free'd per margin. Unfortunately, this prohibits page numbering (the margin is only printed once), so I'll probably end up re-writing this down the line.
* Lint noops. Also fixed getsubopt() to be in unistd.h (noted by joerg@).Kristaps Dzonsons2010-06-082-0/+2

* No functionality changes: just restructuring. DeprecatedKristaps Dzonsons2010-06-086-40/+88
| | | | | terminal_free() in favour of ps_free() and ascii_free(). Moved ps_*() functions into term_ps.c so that they don't clutter up term.c.
