* Consider both `Lp' and `Pp' when stripping prior paragraph marks.Kristaps Dzonsons2010-09-271-1/+6

* Ignore double-`Pp' and `Pp' before `Bd' and `Bl' (unless -compact isKristaps Dzonsons2010-09-271-3/+23

* Made -mdoc `Pp', `Lp', and `br' not FATAL when having arguments.Kristaps Dzonsons2010-08-291-3/+3

* Implement a simple, consistent user interface for error handling.Ingo Schwarze2010-08-201-6/+2
| | | | | | | | | | | | | | | | | We now have sufficient practical experience to know what we want, so this is intended to be final: - provide -Wlevel (warning, error or fatal) to select what you care about - provide -Wstop to stop after parsing a file with warnings you care about - provide consistent exit status codes for those warnings you care about - fully document what warnings, errors and fatal errors mean - remove all other cruft from the user interface, less is more: - remove all -f knobs along with the whole -f option - remove the old -Werror because calling warnings "fatal" is silly - always finish parsing each file, unless fatal errors prevent that This commit also includes a couple of related simplifications behind the scenes regarding error handling. Feedback and OK kristaps@; Joerg Sonnenberger (NetBSD) and Sascha Wildner (DragonFly BSD) agree with the general direction.

* Strip non-graphable input characters from input. The manualsKristaps Dzonsons2010-07-201-19/+19
| | | | | | | | | specifically say that this is not allowed, and were it allowed, output would be inconsistent across output media (-Tps will puke, non-your-charset terminals will puke, etc.). With this done, simplify check_text() to only check escapes and for tabs. Add in a new tab warning, too.
* Remove some FIXMEs: `Ms' accepts arbitrary text, so it can't/shouldn'tKristaps Dzonsons2010-07-191-1/+0
| | | | | | be converted into a symbol. The `Pp' issue has also been fixed.

* Not only for -tag lists, but for -hang, -ohang, -inset, -diag,Ingo Schwarze2010-07-021-6/+3
| | | | | | | and -item list as well, empty bodies are OK, they do not even warrant a warning, much less the error they were throwing. According to kristaps, joerg@ also brought this up some time ago. ok kristaps@ jmc@
* Cached `An' arguments in struct mdoc_an. Note that this isn't aKristaps Dzonsons2010-07-021-14/+19

* Stash `Bf' parameters into struct mdoc_bf.Kristaps Dzonsons2010-07-021-22/+56
|
* Make struct_bl and struct_bd into pointers. This removes the need to doKristaps Dzonsons2010-07-011-52/+65
| | | | | | | | | | | copying on internals after modification. Even more importantly, if an ENDBODY token is provided, it would have been impossible for post-change copying of the data to take place in the BLOCK. This allows it to happen by dint of pointers. Also did some bikeshedding in mdoc_term.c: checking against enum type and explicitly casting to the "post" function to void. This is for my own readability.
* Prevent validator from puking on ENDBODY `Bl' nodes.Kristaps Dzonsons2010-07-011-0/+2

* Notes: this must be done later. \b in the input will cause havoc.Kristaps Dzonsons2010-06-281-0/+5

* minor .Bk fixes:Ingo Schwarze2010-06-271-3/+3
| | | | | | | | * 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 ;)
* Allow registers to be unset. Implement and document the `.nr nS val'.Kristaps Dzonsons2010-06-271-0/+2

* Allow -width for lists to be cached in mdoc_bl. This requires someKristaps Dzonsons2010-06-131-11/+13
| | | | | | 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 Dzonsons2010-06-121-6/+15
| | | | | to 6n if no value is specified" and added regression tests for `Bl' testing against the empty -offset argument.
* Moved `Bl -compact' into cached data. This allowed the removal ofKristaps Dzonsons2010-06-121-12/+13
| | | | scanning the argv list in print_bvspace(), and thus the parent pointer.
* `Bl' is now using a struct instead of a single enum mdoc_list for itsKristaps Dzonsons2010-06-121-12/+13
| | | | cached values. You can probably guess where this is going.
* Removed stipulation that an empty `Bd -offset' will default to 6n. NotKristaps Dzonsons2010-06-121-17/+2
| | | | | | | 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 Dzonsons2010-06-121-12/+59
| | | | | | 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 Dzonsons2010-06-121-20/+42
| | | | | | | | | | | 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').
* Squash bug noted by Ulrich Spoerlein where "-" were being converted toKristaps Dzonsons2010-06-091-10/+7
| | | | | | | | | 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.
* Consolidated list processing to a single loop in mdoc_validate.c. ThisKristaps Dzonsons2010-06-031-63/+105
| | | | | | | | | | relieves having to repeat running over the argument list in mdoc_action.c and mdoc_validate.c. Default to LIST_item for type-less lists (groff technically doesn't do this: it just ignores the `It' lines altogether). Make MANDOC_LISTTYPE be a recoverable error.
* Cleanup post_bl_head() to use enum mdoc_list (avoid traversing thatKristaps Dzonsons2010-05-311-10/+13
| | | | | | | | list). Reverted MANDOC_COLUMNS to be a bad-bad syntax error: we don't, and apparently never have, allowed mixing of -column syntaxes. This would have segfaulted if encountered.
* Clean up the validation code for `It' macros: use enum mdoc_listKristaps Dzonsons2010-05-311-71/+39
| | | | | instead of iterating over arguments and only scan with `-column', which needs the count of arguments.
* Remove enum mdocargerr from phrase() (unused).Kristaps Dzonsons2010-05-311-0/+1
| | | | | | | | | | | | | | 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 Dzonsons2010-05-301-7/+9
| | | | | | | | | | 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.
* Make check for case a little more intuitive (suggested by joerg@).Kristaps Dzonsons2010-05-301-3/+1
|
* Made `Dt' default to LOCAL and UNKNOWN instead of local and unknown (note case).Kristaps Dzonsons2010-05-301-3/+24
| | | | | | | | Have `Dt' default to UNKNOWN if it's an empty string. Raise a warning if `Dt' title isn't capitalised. Sync'd `Dt' documentation with reality.
* Documented `Ud'.Kristaps Dzonsons2010-05-261-5/+16
| | | | | | | | | | | Proper EOS handling for `Rv', `Ex', `Ud', and `Bt'. Both `Bt' and `Ud' now warn about and discard line arguments (reported by Ulrich Spoerlein). Collapsed posts_xr into posts_wtext (harmless: they're the same thing). Added regressions for `Ud' and `Bt'.
* Fixed `Lb' to be in_line (reported by Ulrich Spoerlein).Kristaps Dzonsons2010-05-261-2/+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).
* Smarten BADCHAR check to allow ASCII_HYPH.Kristaps Dzonsons2010-05-251-1/+1
| | | | Fix index.sgml not to puke (the relevant section will be re-written for the release anyway, but I hate seeing errors).
* Lifted 64-byte max width for Sh (now BUFSIZ).Kristaps Dzonsons2010-05-241-3/+4
|
* Increase performance by stashing the list type in struct mdoc_node.Kristaps Dzonsons2010-05-171-18/+10
| | | | | | | This will eventually be used so that mdoc_macro can known whether to dump list line arguments into the body (`Bl -column' overflowing). Remove a2list() and arg_listtype() because of this.
* Enable the unified error/warning enumeration in mandoc.h that'sKristaps Dzonsons2010-05-171-98/+148
| | | | | | | | | | | 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.
* LIBRARY can also occur in section 9.Kristaps Dzonsons2010-05-151-9/+8
| | | | | | All manual sections (unknown, 3p, 3f, etc.) correctly handled by -mdoc. Useful warning printed if unknown manual section. Checking for manual sections (e.g., LIBRARY) checks only first character, so 3p, 3f, etc. are free.
* Remove in-manual-section warnings for Fd and Lb (ok joerg@, schwarze@).Kristaps Dzonsons2010-05-141-47/+3

* mdoc_atosec -> mdoc_str2sec (consistent with str2 being different from a2).Kristaps Dzonsons2010-05-121-4/+7
| | | | | Changed ordering of sections (EXIT STATUS moved around), argued for by Ulrich Sporlein. Fixed mdoc_str2sec not to use weird structure.
