* 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@
* Allow EQN data to be pushed down into libmdoc via mdoc_addeqn(). OnlyKristaps Dzonsons2011-02-091-0/+24
| | | | the adding itself is implemented; equation data is not yet shown.
* Put tbl_alloc function right into the addspan() one, as this is the onlyKristaps Dzonsons2011-02-081-20/+9
| | | | place that it's called.
* Use tbl_span line number for warnings/errors.Kristaps Dzonsons2011-02-061-2/+1
|
* Let the line-number of a tbl_span be remembered.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
| | | | ending of scopes and drop stray scope-endings.
* Make sure that the manual section defaults to `1' if it's unset. ThisKristaps Dzonsons2010-12-011-0/+2
| | | | | behaviour only happens if `Dt' isn't specified, which can be exhibited by running mandoc -mdoc on a man manual.
* mdoc_action.c is no more. Attic it and remove it from the Makefile.Kristaps Dzonsons2010-11-301-4/+0
| | | | | Remove references to MDOC_ACTED (it was only assertions) and the pre- and post-action functions.
* Merge from OpenBSD right after 1.10.6; now back to full sync.Ingo Schwarze2010-09-271-7/+4
| | | | | | | | | | * mdoc.c: blank lines outside literal mode are more similar to .sp than .Pp * backslashes do not terminate macros; partial revert of mdoc.c 1.164; the intention of that commit is fully achieved in roff.c * mdoc_term.c: no need to list the same prototype twice * mdoc_validate.c: drop .Pp before .sp just like .Pp before .Pp * fix off-by-one found by jsg@ with parfait, OpenBSD term_ps.c 1.12 ok kristaps@
* Allow `.xx\}' where xx is a macro (e.g., `.br\}') to close scope. This isKristaps Dzonsons2010-08-291-2/+5
| | | | | | 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.
* simplify the code copying the macro name, and sync theIngo Schwarze2010-08-081-8/+5

* Clean out the isgraph() checks in mdoc.c and man.c. These code pathsKristaps Dzonsons2010-08-071-12/+1
| | | | | were never taken since main.c begin skipping over unrecognisable characters, so they were noops.
* "Groff allows the initial macro on a line to be delimited by a space ofKristaps Dzonsons2010-08-071-6/+15

* Text ending in a full stop, exclamation mark or question markIngo Schwarze2010-07-181-1/+1
| | | | | | | | | | | | | | | | | | should not flag the end of a sentence if: 1) The punctuation is followed by closing delimiters and not preceded by alphanumeric characters, like in "There is no full stop (.) in this sentence" or 2) The punctuation is a child of a macro and not preceded by alphanumeric characters, like in "There is no full stop .Pq \&. in this sentence" "looks fine" to kristaps@; tested by jmc@ and sobrado@
* Re-constitution of `ds' symbol processing. First, push theKristaps Dzonsons2010-07-071-1/+0
| | | | | | | | | roff_getstr() family of functions into roff.c with the "first_string" directly in struct roff. Second, pre-process each line for reserved words in libroff, splicing and re-running a line if it has one (this allows defined symbols to be macros). Remove term.c's invocation of the roff_getstrn() function. Removed function documentation in roff.3 and added roff.7 `ds' documentation.
* Assert my copyright, making it explicit that i'm granting the same licenseIngo Schwarze2010-07-041-1/+2

* Make struct_bl and struct_bd into pointers. This removes the need to doKristaps Dzonsons2010-07-011-4/+12
| | | | | | | | | | | 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.
* In the mdoc(7) parser, inspect roff registers early such that all partsIngo Schwarze2010-07-011-14/+18
| | | | | | | | | | | | of the parser can use the resulting cues. In particular, this allows to use .nr nS to force SYNOPSIS-style .Nm indentation outside the SYNOPSIS as needed by ifconfig(8). To actually make this useable, .Pp must rewind .Nm, or the rest of the section would end up indented. Implement a quick hack for now, a generic solution can be designed later. ok kristaps@ and tested by sobrado@
* Support for badly nested blocks, written around the time ofIngo Schwarze2010-06-291-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | 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@

| | | | | | | | | 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.
