* Support setting arbitrary roff(7) number registers,Ingo Schwarze2013-10-051-6/+4
| | | | | | | | | | | | | | preserving read support for the ".nr nS" SYNOPSIS state register. Inspired by NetBSD roff.c rev. 1.18 (Christos Zoulas, March 21, 2013), but implemented differently. I don't want to have yet another different implementation of a hash table in mandoc - it would be the second one in roff.c alone and the fifth one in mandoc grand total. Instead, i designed and implemented roff_setreg() and roff_getreg() to be similar to roff_setstrn() and roff_getstrn(). Once we feel the need to optimize, we can introduce one common hash table implementation for everything in mandoc.
* Cleanup naming of local variables to make the code easier on the eye:Ingo Schwarze2012-11-171-140/+140
| | | | | | | | Settle for "struct man *man", "struct mdoc *mdoc", "struct meta *meta" and avoid the confusing "*m" which was sometimes this, sometimes that. No functional change. ok kristaps@ some time ago
* Fix a crash triggered by .Bl -tag .It Xo .El .Sh found by florian@.Ingo Schwarze2012-11-161-0/+3
| | | | | | | | | | | | | | | * When allocating a body end marker, copy the pointer to the normalized block information from the body block, avoiding the risk of subsequent null pointer derefence. * When inserting the body end marker into the syntax tree, do not try to copy that pointer from the parent block, because not being a direkt child of the block it belongs to is the whole point of a body end marker. * Even non-callable blocks (like Bd and Bl) can break other blocks; when this happens, postpone closing them out in the usual way. Completed and tested at the OpenBSD impromptu Coimbra hackathon (c2k12). Thanks to Pedro Almeida and the Laborat'orio de Computa,c~ao Avan,cada da Universidade de Coimbra (http://www.uc.pt/lca) for their hospitality!
* Fix handling of paragraph macros inside lists:Ingo Schwarze2012-07-181-1/+9
| | | | | | | * When they are trailing the last item, move them outside the list. * When they are trailing any other none-compact item, drop them. OpenBSD rev. mdoc_validate.c 1.107, mdoc.c 1.91
* The mdoc(7) \*(Ba predefined string actually forces roman font;Ingo Schwarze2012-07-181-1/+1
| | | | | | | | | | | | that's stupid because it may break enclosing font changes, but let's do the same for groff bug compatibility. --> Never use \*(Ba, use just plain "|"! <-- Also, predefined strings are already expanded by the roff(7) parser, so the mdoc(7) parser has to look for the expanded string. OpenBSD rev. mdoc.c 1.90 and predefs.in 1.3
* Several -mdoc parser improvements related to vertical spacing:Ingo Schwarze2012-07-161-1/+2
| | | | | | | | | | * So far, .Pp and .Lp were removed before paragraph type blocks. * Now also remove .br before paragraph type blocks. * Treat .Lp as a paragraph like .Pp, so remove .Pp, .Lp, .br before it. * Do not treat .sp as a paragraph, don't remove anything before it. * After .Sh, .Ss, .Pp, and .Lp, remove .Pp, .Lp, .sp, .br, and blank lines. * After .sp and .br, remove .br. OpenBSD rev. mdoc.c 1.89 and mdoc_validate.c 1.106
* Add `cc' support.Kristaps Dzonsons2012-06-121-1/+1
| | | | | | | | | | | | | | | This was reported by espie@ and in the TODO. Caveat: `cc' has buggy behaviour when invoked in groff(1) and followed by a line-breaking control character macro, e.g., in a -man doc, .cc | .B foo 'B foo |cc 'B foo will cause groff(1) to behave properly for `.B' but inline the macro definition for `B' when invoked with the line-breaking macro.
* Support -Ios='OpenBSD 5.1' to override uname(3) as the source of theIngo Schwarze2012-05-271-1/+2
| | | | | | | | | | default value for the mdoc(7) .Os macro. Needed for man.cgi on the OpenBSD website. Problem with man.cgi first noticed by deraadt@; beck@ and deraadt@ agree with the way to solve the issue. "Please check them in and I'll look into them later!" kristaps@

* An implementation of `tr'. This routes allocations of TEXT nodesKristaps Dzonsons2011-07-281-1/+1
| | | | | | | through libroff, which does the appropriate translations of `tr'. This is SLOW: it uses the backend of `ds' and `de', which is a simple linear list. However, unlike `ds' and `de', it iterates over EACH CHARACTER of the entire file looking for replacements.
* Simply word allocation in libmdoc and libman.Kristaps Dzonsons2011-07-271-8/+1

* Disable in-line eqn processing for a bit.Kristaps Dzonsons2011-07-271-1/+5

* First, roff_res() has no need to invoke ROFF_RERUN: since it's executedKristaps Dzonsons2011-07-271-5/+0
| | | | | | | | | | | before any other roff processing occurs, it's Ok to just let it do its thing and pass through. Also, make sure this function is ALWAYS called, not just when first_string is defined. Second, add a new function, roff_parsetext(), that post-processes non-macro lines. This, for the time being, amounts to detecting soft hyphens. This fixes a long-standing bug in that -man now has proper hyphen breaking!
* Implement the first steps of equation parsing from within libmdoc.Kristaps Dzonsons2011-07-251-1/+53
| | | | | | This consists of a shim around the text parser that calls out to libroff if equation components exist on the line. Right now this will do nothing, as the equation delimiter always returns nil.
* Finish the eqn syntactic parser. This correctly parses terms and doesKristaps Dzonsons2011-07-211-2/+2
| | | | | | | the proper `define' dance, which amounts to pure word-replace (you can, say, define `foo' as `define' then define `define' as something else). eqn.c is now ready for some semantic parsing of `box' and `eqn' productions as defined by the grammar.
* Make `struct roff' be passed into libmdoc and libman upon creation.Kristaps Dzonsons2011-07-181-4/+4
| | | | | This is required for supporting in-line equations. While here, push registers properly into roff and add an set/get/mod interface.
* Have libman and libmdoc use mandoc_getcontrol() to determine whether aKristaps Dzonsons2011-03-281-41/+24
| | | | macro has been invoked. libroff is next.
* libmdoc.h and libman.h were including mdoc.h and man.h, respectively.Kristaps Dzonsons2011-03-221-0/+1
| | | | | Don't have them do that (includes in header files = faugh), and have individual files directly include these files.
* Move mandoc_isdelim() back into libmdoc.h. This fixes an unreportedKristaps Dzonsons2011-03-221-0/+44
| | | | | | | | | error where (1) -man pages were punctuating delimiters (e.g., `.B a ;') and where (2) standalone punctuation in -mdoc or -man (e.g., ";" on its own line) would also be punctuated. This introduces a small amount of complexity of mdoc_{html,term}.c must manage their own spacing with running print_word() or print_text(). The check for delimiting now happens in mdoc_macro.c's dword().
* Consolidate messages. Have all parse-time messages (in libmdoc,Kristaps Dzonsons2011-03-201-22/+6
| | | | | | | | | libroff, etc., etc.) route into mandoc_msg() and mandoc_vmsg(), for the time being in libmandoc.h. This requires struct mparse to be passed into the allocation routines instead of mandocmsg and a void pointer. Then, move some of the functionality of the old mmsg() into read.c's mparse_mmsg() (check against wlevel and setting of file_status) and use main.c's mmsg() as simply a printing tool.
* Clean-up in libmdoc: fix last checks for mdoc_*msg return value, thenKristaps Dzonsons2011-03-171-2/+2
| | | | | make mdoc_vmsg not return an int. libmdoc is now completely clean of return-value checks from the message subsystem.
* Plug memory leak of normalised-date field.Kristaps Dzonsons2011-03-151-0/+2
|
* Clean up date handling,Ingo Schwarze2011-03-071-3/+4
| | | | | | | | | | | | as a first step to get rid of the frequent petty warnings in this area: - always store dates as strings, not as seconds since the Epoch - for input, try the three most common formats everywhere - for unrecognized format, just pass the date though verbatim - when there is no date at all, still use the current date Originally triggered by a one-line patch from Tim van der Molen, <tbvdm at xs4all dot nl>, which is included here. Feedback and OK on manual parts from jmc@. "please check this in" kristaps@

* Use tbl_span line number for warnings/errors.Kristaps Dzonsons2011-02-061-2/+1

* Clarified the role of MDOC_HALT in libmdoc functions by having accessorKristaps Dzonsons2011-01-031-9/+8
| | | | | | | | | | functions assert() if they're called after MDOC_HALT is set. This makes more sense than returning 0 because this return value is used for parse errors, not programme-flow errors, and it's inconsistent to use the same value for both. Plus, prior to this, I'd return 0 without printing an error message, which would cause failure to go unreported to the operator.
* Add -man support for tables. Like -mdoc, this consists of anKristaps Dzonsons2011-01-011-0/+2
| | | | | | | external-facing function man_addspan() (this required shuffling around the descope routine) and hooks elsewhere. Also fixed mdoc.c's post-validation of tables.
* Add table processing structures to -mdoc. This consists of anKristaps Dzonsons2011-01-011-0/+36
| | | | | | external-facing function mdoc_addspan(), then various bits to prohibit printing and scanning (this requires some if's to be converted into switch's).
* Clean up {mdoc,man}_pmsg and vmsg invocations (ignore return values).Kristaps Dzonsons2011-01-011-14/+16

* Specifying both %T and %J in an `Rs' block causes the title to be quotedKristaps Dzonsons2010-12-251-0/+2
| | | | | instead of underlined. This only happens in -Tascii, as -T[x]html both underlines and italicises.
* As per schwarze@'s suggestions, roll back the refcount structure inKristaps Dzonsons2010-12-241-6/+44
| | | | | | | | favour of a simpler shim for normalised data in the node allocation and free routines. This removes the need to bump and copy references within validator handlers, removes a pointer redirect, and also kills the refcount structure itself. Data is assumed to "live" either in a MDOC_BLOCK or MDOC_ELEM and is copied accordingly.
* Implement reference-counted version of original union mdoc_data. ThisKristaps Dzonsons2010-12-221-22/+6
| | | | | | | simplifies clean-up and allows for more types without extra hassle. Also made in-line literal types in -T[x]html use CODE instead of SPAN to match how literal blocks use PRE.
* Migrate `An' to use a pointer in its data, like everybody else. This isKristaps Dzonsons2010-12-161-0/+3
| | | | | the first step to having a simpler ref-counted system for "data" associated with a node.
* Add a "last child" member of struct mdoc_node.Kristaps Dzonsons2010-12-151-0/+2
| | | | | | | Remove `Pp' or `Lp' if it is the FIRST or LAST child of an `Sh' or `Sh' body. Make "skipping paragraph" be an error, not a warning, as information (an invoked macro) is ignored.
* Merge schwarze@'s relaxation of scope-breaking rules: allow implicitKristaps Dzonsons2010-12-061-3/+1

* Merge from OpenBSD right after 1.10.6; now back to full sync.Ingo Schwarze2010-09-271-7/+4

| | | | | | experimental and hasn't been rigorously tested. It's only implemented in -mdoc for the time being. This is absolutely required for pod2man. It does, however, make the pod2man preamble be processed in full.
* Implement a simple, consistent user interface for error handling.Ingo Schwarze2010-08-201-29/+6
| | | | | | | | | | | | | | | | | 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.
