* Allow leading and trailing vertical lines,Ingo Schwarze2014-03-281-0/+1
| | | | | | | and format them in the same way as groff. While here, do not require whitespace before vertical lines in layout specifications. Issues found by bentley@ in mpv(1).
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-231-6/+1
| | | | | | | functions used for multiple languages (mdoc, man, roff), for example mandoc_escape(), mandoc_getarg(), mandoc_eos(), and generic auxiliary functions. Split the auxiliaries out into their own file and header. While here, do some #include cleanup.
* Without the MPARSE_SO option, if the file contains nothing but aIngo Schwarze2014-03-191-1/+1
| | | | | | single .so request, do not read the file pointed to, but instead let mparse_result() provide the file name pointed to as a return value. To be used by makewhatis(8) in the future.
* Generalize the mparse_alloc() and roff_alloc() functions by givingIngo Schwarze2014-03-191-10/+6
| | | | | | | | them an "options" argument, replacing the existing "inttype" and "quick" arguments, preparing for a future MPARSE_SO option. Store this argument in struct mparse and struct roff, replacing the existing "inttype", "parsetype", and "quick" members. No functional change except one tiny cosmetic fix in roff_TH().
* Implement the \: (optional line break) escape sequence,Ingo Schwarze2014-01-221-0/+1
| | | | | | | documented in the Ossanna-Kernighan-Ritter troff manual and also supported by groff. Missing feature reported by Steffen Nurpmeso <sdaoden at gmail dot com>.
* Add an option -Q (quick) to mandocdb(8)Ingo Schwarze2014-01-051-1/+1
| | | | | | | | | | | | | | | for accelerated generation of reduced-size databases. Implement this by allowing the parsers to optionally abort the parse sequence after the NAME section. While here, garbage collect the unused void *arg attribute of struct mparse and mparse_alloc() and fix some errors in mandoc(3). This reduces the processing time of mandocdb(8) on /usr/share/man by a factor of 2 and the database size by a factor of 4. However, it still takes 5 times the time and 6 times the space of makewhatis(8), so more work is clearly needed.
* Since the functions in read.c are part of the mandoc(3) library,Ingo Schwarze2014-01-021-1/+9
| | | | | | do not print to stderr. Instead, properly use the mmsg callback. Issue noticed by Abhinav Upadhyay <er dot abhinav dot upadhyay at gmail dot com> and Thomas Klausner <wiz at NetBSD>.
* Remove duplicate const specifiers from the declaration of mandoc_escape().Ingo Schwarze2013-12-301-2/+1
| | | | | Found by Thomas Klausner <wiz at NetBSD dot org> using clang. No functional change.
* Cleanup suggested by gcc-4.8.1, following hints by Christos Zoulas:Ingo Schwarze2013-10-051-1/+2
| | | | | | | | - avoid bad qualifier casting in roff.c, roff_parsetext() by changing the mandoc_escape arguments to "const char const **" - avoid bad qualifier casting in mandocdb.c, index_merge() - do not complain about unused variables in test-*.c - garbage collect a few unused variables elsewhere
* One of the WARNING messages has to use the word "section" twice in twoIngo Schwarze2013-09-161-1/+1
| | | | | | | | | | different meanings, that cannot be helped. But we can make this less confusing by stating that the second instance refers to stuff like (2), (3), and (9), and by adding the sections header the first instance refers to, for example ERRORS or RETURN VALUES. Source for confusion noticed by Jan Stary <hans at stare dot cz>, better wording suggested by jmc@, tweaked by me.
* Implement the roff(7) font-escape sequence \f(BI "bold+italic".Ingo Schwarze2013-08-081-0/+1
| | | | | This improves the formatting of about 40 base manuals and reduces groff-mandoc formatting differences in base by about 5%.
* Rudimentary implementation of the .it request (input line trap).Ingo Schwarze2013-07-131-1/+2
| | | | | | | | | | As with any low-level roff request involving subtle interactions with macro internals, this implementation is not exact, but it does handle the simplest cases. This request occurs in man(7) code generated from DocBook, for example mysql(1) and yasm_arch(7). Thanks to brad@ for reporting the issue back in January 2011.
* The name "struct tbl" was badly misleading for two reasons:Ingo Schwarze2013-05-311-2/+2
| | | | | | | 1) This struct almost exclusively contains the table options. 2) Information about the table as a whole is actually in "struct tbl_node". Besides, "struct tbl" was almost impossible to search for. So rename it to "struct tbl_opts". No functional change.
* Do not crash on stray .Ta macros found outside column lists.Ingo Schwarze2012-11-191-0/+2
| | | | Problem reported by jmc@, thanks.
* Warn about unknown volume or arch in Dt macro arguments;Ingo Schwarze2012-11-161-0/+1
| | | | patch written by Nicolas Joly <njoly at pasteur dot fr>.
* Fix handling of paragraph macros inside lists:Ingo Schwarze2012-07-181-0/+1
| | | | | | | * 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 post_nm() validation function crashed when the first .Nm child nodeIngo Schwarze2012-07-121-1/+1
| | | | | | | | | | was a non-text node. Fix this by rewriting post_nm() to always set the meta name to UNKNOWN when the name is missing or unusable. While here, make MANDOCERR_NONAME an ERROR, as it usually renders the page content unintelligible. Bug reported by Maxim <Belooussov at gmail dot com>, thanks. OpenBSD rev. 1.105
* Implement the roff \z escape sequence, intended to output the nextIngo Schwarze2012-05-311-1/+2
| | | | | | | | | | | | | | | | | | character without advancing the cursor position; implement it to simply skip the next character, as it will usually be overwritten. With this change, the pod2man(1) preamble user-defined string \*:, intended to render as a diaeresis or umlaut diacritic above the preceding character, is rendered in a slightly less ugly way, though still not correctly. It was rendered as "z.." and is now rendered as ".". Given that the definition of \*: uses elaborate manual \h positioning, there is little chance for mandoc(1) to ever render it correctly, but at least we can refrain from printing out a spurious "z", and we can make the \z do something semi-reasonable for easier cases. "just commit" kristaps@
* Do not handle vertical lines as additional tbl(7) columns,Ingo Schwarze2012-05-271-9/+2
| | | | | | | | | | | | | | | | instead save their properties with the following column. This simplifies layout parsing and saves a lot of code related to column handling. At output time, print all white space and vertical lines separating columns before printing the following column, and none after printing the preceding column, considerably simplifying white space handling and width calculations. No functional change, but it saves 150 lines of code, and it allows the next patch to tbl_term.c, tbl_literal(). "Please check them in and I'll look into them later!" kristaps@
* Support -Ios='OpenBSD 5.1' to override uname(3) as the source of theIngo Schwarze2012-05-271-2/+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@

* Const-ify some mchars arguments. I think these are non-const for historicalKristaps Dzonsons2011-11-081-2/+2

* When the HEAD scope of .TP is broken by another block macro,Ingo Schwarze2011-11-071-1/+0
| | | | | | | | do not abort with a FATAL error, but report a report a WARNING, remove the broken .TP from the syntax tree, and prod on. Reported repeatedly by ports people, at least by brad@ and jeremy@. Also fixes rendition(4) in Xenocara. ok kristaps@
* If -Tman is specified and input is -man, echo the preprocessed (`so'Kristaps Dzonsons2011-10-061-16/+17
| | | | | | | | | | | | | | replaced by file) input. This replaces earlier behaviour of doing nothing, which I found unexpected (mandoc should always output). This requires a buffer in read.c that saves the input lines before being parsed, with a special hook if `so' is invoked. This buffer is just flushed to output if -mman is the input. While mucking around doing this, I also alpha-ordered the mandoc.h functions. Ok schwarze@, with no screaming when the polished patch was published.

* Complete eqn.7 parsing. Features all productions from the original 1975Kristaps Dzonsons2011-07-211-4/+21
| | | | | | | | CACM paper in an LR(1) parse (1 -> eqn_rewind()). Right now the code is a little jungly, but will clear up as I consolidate parse components. The AST structure will also be cleaned up, as right now it's pretty ad hoc (this won't change the parse itself). I added the mandoc_strndup() function will here.

* Finish the eqn syntactic parser. This correctly parses terms and doesKristaps Dzonsons2011-07-211-1/+1
| | | | | | | 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.

| | | | | | | | | | change any code but for renaming functions and types to be consistent with other mandoc.h stuff. The reason for moving into libmandoc is that the rendering of special characters is part of mandoc itself---not an external part. From mandoc(1)'s perspective, this changes nothing, but for other utilities, it's important to have these part of libmandoc. Note this isn't documented [yet] in mandoc.3 because there are some parts I'd like to change around beforehand.
* Remove a2roffdeco() and mandoc_special() functions and replace them withKristaps Dzonsons2011-04-091-0/+16
| | | | | | | | | | | | | | | | | | a public (mandoc.h) function mandoc_escape(), which merges the functionality of both prior functions. Reason: code duplication. The a2roffdeco() and mandoc_special() functions were pretty much the same thing and both quite complex. This allows one function to receive improvements in (e.g.) subexpression handling and performance, instead of having to replicate functionality. As such, the mandoc_escape() function already handles a superset of the escapes handled in previous versions and has improvements in performance (using strcspn(), for example) and reliable handling of subexpressions. This code Works For Me, but may need work to catch any regressions. Since the benefits are great (leaner code, simpler API), I'd rather have it in-tree than floating as a patch.
