* Header for `PP', `P', and `LP' should never be printed.Kristaps Dzonsons2010-12-062-4/+7

* Allow HP/IP/etc. to have no arguments, as they're optional. From a field-Kristaps Dzonsons2010-12-061-4/+2
| | | | tested patch by schwarze@.
* Allow multiple ELINE macros without raising a fatal error. From a field-Kristaps Dzonsons2010-12-061-26/+10
| | | | tested patch by schwarze@.
* Track down a bug of empty `de XX' macros causing uncertain behaviour byKristaps Dzonsons2010-12-062-12/+24
| | | | | | | | | | returning empty strings in roff_getstrn() instead of NULL. This caused maddeningly irregular segfaults in the pod2man preamble for `de IX'. But only on DEC alpha. Also integrate the kinda-probably-safe assertion relaxation in term.c, field-tested by schwarze@. This allows ALL [unpreprocessed] base and xenocara manuals for all BSD systems to run without segfault.
* Merge schwarze@'s relaxation of scope-breaking rules: allow implicitKristaps Dzonsons2010-12-064-28/+28

* Remove `Sp', `Vb', and `Ve' (as per schwarze@'s changes in OpenBSD),Kristaps Dzonsons2010-12-058-79/+15
| | | | which are now accomodated for the new libroff modifications.
* Remove repeat notification of -width omission. From a patch by schwarze@.Kristaps Dzonsons2010-12-051-7/+2

* Remove long-standing FIXME regarding the consolidation of WIDTHARG andKristaps Dzonsons2010-12-053-9/+5
| | | | NOARGV warnings. From patch by schwarze@.
* Merge schwarze@'s patch to allow uname() to fail without causing an exit.Kristaps Dzonsons2010-12-053-8/+11

* Merge schwarze@'s changes allowing nested displays. Tweak the patch byKristaps Dzonsons2010-12-056-20/+28
| | | | | | | making sure output doesn't add a superfluous newline with the nested displays. Also add a COMPATIBILITY note. Rename a macro (DATESIZ) to be in line with OpenBSD (DATESIZE).
* Track the parser status both per file (file_status), such thatIngo Schwarze2010-12-021-14/+19
| | | | | | | | we can for example skip rendering on FATAL parsing errors, and globally (exit_status), such that we know what to return. Without this, following files produced no rendered output once a single file suffered from a FATAL error. Bug reported by kristaps@, fix by me.
* Merge schwarze@'s changes to allow for user-defined strings. ThisKristaps Dzonsons2010-12-021-73/+214
| | | | | | | | primarily adds a roff_userdef() function for parsing new defines and modifies the look-up procedure. NOTE: there is a bug hidden away in this update that causes an infinite loop in some pages. The cause is for the moment unknown.
* Fix enum/int mixing.Kristaps Dzonsons2010-12-011-3/+4

* Merge OpenBSD's `so' handling (plus some documentation). Great work toKristaps Dzonsons2010-12-013-3/+34
| | | | schwarze@ and joerg@ for his comments!
* Make sure that the manual section defaults to `1' if it's unset. ThisKristaps Dzonsons2010-12-011-1/+3
| | | | | behaviour only happens if `Dt' isn't specified, which can be exhibited by running mandoc -mdoc on a man manual.
* Fix a subtle error in the new main.c where the parse type (mdoc/man) wasKristaps Dzonsons2010-12-011-86/+157
| | | | | | | | | | | | | | | being inherited during the parse sequence, making pset() meaningless. Make sure that the mdoc/man curp pointer is set for each parse from a persistent object. This flushes out an obscure error where `man' pages called with `mdoc' will parse and segfault due to a missing title. Never happened earlier because `mdoc' pages were guaranteed to have a prologue. Fix this later. Also document the new main.c functions. Please make sure these sort of things are documented! Throw in some whitespace to make things a bit more readable.
* Merge restructuring of main.c code. This provided by schwarze@ and inspectedKristaps Dzonsons2010-12-012-131/+218
| | | | | | | | carefully by joerg@. Merge roff.h header for compilation's sake (this is not yet implemented in roff.c.). THIS IS A BUGGY CHECK-IN. The manual type is erroneously kept between runs of the compiler. This is a known bug.
* Fixed a goddamn subtle error causing MDOC_LITERAL to remain set after aKristaps Dzonsons2010-12-011-2/+2
| | | | call to `Dl' or `Bd -literal' or unfilled.
* Re-ordering of roff requests as per OpenBSD.Kristaps Dzonsons2010-12-013-7/+17
| | | | Made `rm' be an error (again, OpenBSD...).
* Low-hanging fruit: add OpenBSD's `ad', `hy', `ne', and `nh' handling.Kristaps Dzonsons2010-12-011-5/+13
| | | | Rename roff_line() -> roff_line_ignore().
* Restore the Id tag that i clobbered in my previous commit,Ingo Schwarze2010-11-301-1/+1
| | | | as pointed out by kristaps@. Sorry!
* Merge OpenBSD mdoc.7 rev. 1.56 and 1.57:Ingo Schwarze2010-11-301-16/+26

* Simplify the many if ( ! mdoc_nmsg()) return(0) etc. calls with just theKristaps Dzonsons2010-11-301-169/+158
| | | | | | | | | | error printing, as this is superseded by exit_status in main.c. Make check_argv() and check_text() return void. Make MDOC_Std test in check_argv() to pre_std(). Re-write post_root() to check more conditions before returning.
* mdoc_action.c is no more. Attic it and remove it from the Makefile.Kristaps Dzonsons2010-11-305-239/+8
| | | | | Remove references to MDOC_ACTED (it was only assertions) and the pre- and post-action functions.
* Moved all prologue actions from mdoc_action.c into mdoc_validate.c. TheKristaps Dzonsons2010-11-302-339/+301

* Move post_bl() and subfunctions from mdoc_action.c into mdoc_validate.c.Kristaps Dzonsons2010-11-302-154/+159

* Move -column list validation and normal-formisation from mdoc_action.cKristaps Dzonsons2010-11-302-69/+58

* Migrate `Nm' and `Pa' handling from mdoc_action.c into mdoc_validate.c.Kristaps Dzonsons2010-11-293-53/+45
| | | | Document that `Pa' is replaced by a tilde, just like `Mt'.
* Remove left-over rsord[] in mdoc_actions.c.Kristaps Dzonsons2010-11-294-106/+82
| | | | | | | | | Remove MANDOCERR_BADLIB (not used). Moved `St' handling from mdoc_action.c into mdoc_validate.c. Moved relevant MDOC_LITERAL macros (`Dl', `Bd' subtypes) from mdoc_action.c into mdoc_validate.c.

* Move `Sh' validation from mdoc_action.c. into mdoc_validate.c.Kristaps Dzonsons2010-11-292-88/+48
| | | | | Surprisingly, both functions were doing pretty much the same thing. Make sure that the changes incorporate the union of both.
* Clarifying role of pre_pp (now pre_par), which was confusing me due toKristaps Dzonsons2010-11-291-8/+10
| | | | | its name. Added some more documentation just for clarity's sake. No functional change.

* Move `Mt', `Ar', and `Li' handling from mdoc_action.c into mdoc_validate.c.Kristaps Dzonsons2010-11-296-63/+61
| | | | | | | | Clarify that `Mt' gets a default `~' (as per groff 1.20) and document it in mdoc.7. Made `Lk' be removed in mdoc_macro.c if it has no arguments. This fixes segfaults in mdoc_{term,html}.c that nobody's managed to raise yet.
* Migrate action for `Rs' into mdoc_validate.c.Kristaps Dzonsons2010-11-292-103/+106
| | | | | | Remove superfluous in-line order_rs function. Merge `Rs' validations {BLOCK, BODY} -> {BODY}. Make invalid children of `Rs' raise an error but otherwise be allowed.

* Referring to terms explained in other manuals, always use .Xr.Ingo Schwarze2010-10-291-4/+4
| | | | | | Otherwise, hyperlinks can't be produced and people will likely miss the additional information available. Suggested by deraadt@.
