* Clean up messages related to plain text and to escape sequences.Ingo Schwarze2014-07-061-8/+9
| | | | | * Mention invalid escape sequences and string names, and fallbacks. * Hierarchical naming.
* Cleanup with respect to bad macro arguments.Ingo Schwarze2014-07-051-10/+9
| | | | | | | | * Fix .Sm with invalid arg: move arg out and toggle mode. * Promote "unknown standard" from WARNING to ERROR, it loses information. * Delete MANDOCERR_BADWIDTH, it would only indicate a mandoc(1) bug. * Do not report MANDOCERR_BL_LATETYPE when there is no type at all. * Mention macro names, arguments and fallbacks.
* Cleanup regarding -offset and -width:Ingo Schwarze2014-07-051-2/+3
| | | | | | | * Bugfix: Last one wins, not first one. * Fix .Bl -width without argument: it means 0n, so do not ignore it. * Report macro names, argument names and fallbacks in related messages. * Simplify: Garbage collect auxiliary variables in pre_bd() and pre_bl().
* Clean up messages regarding excess arguments:Ingo Schwarze2014-07-041-4/+5
| | | | | | * Downgrade ".Bf -emphasis Em" from FATAL to WARNING. * Mention the macros, the arguments, and the fallbacks. * Hierarchical naming.
* Clean up messages related to missing arguments.Ingo Schwarze2014-07-041-9/+8
| | | | | | | | | * Do not warn about empty -column cells, they seem valid to me. * Downgrade empty item and missing -std from ERROR to WARNING. * Hierarchical naming. * Descriptive, not imperative style. * Mention macro names, argument names, and fallbacks. * Garbage collect some unreachable code in post_it().
* Fix formatting of empty .Bl -inset item heads.Ingo Schwarze2014-07-031-2/+2
| | | | | | Downgrade empty item heads from ERROR to WARNING. Show the list type in the error message. Choose better variable names for nodes in post_it().
* MANDOCERR_NOARGS reported three completely unrelated classes of problems.Ingo Schwarze2014-07-031-2/+4
| | | | Split the roff(7) parts out of it and report the request names for these cases.
* Improve and test the messages about empty macros,Ingo Schwarze2014-07-021-2/+2
| | | | in particular reporting the macro names involved.
* Disentangle the MANDOCERR_CHILD message, which reported threeIngo Schwarze2014-07-021-2/+4
| | | | | completely different things, into three distinct messages. Also mention the macro names we are talking about.
* Clean up warnings related to macros and nesting.Ingo Schwarze2014-07-021-7/+7
| | | | | | | * Hierarchical naming of enum mandocerr items. * Improve the wording to make it comprehensible. * Mention the offending macro. * Garbage collect one chunk of ancient, long unreachable code.
* Improve "skipping paragraph macro" messages,Ingo Schwarze2014-07-021-3/+3
| | | | showing which macro was skipped and before or after what.
* Implement the obsolete macros .En .Es .Fr .Ot for backward compatibility,Ingo Schwarze2014-07-021-2/+2
| | | | | since this is hardly more complicated than explicitly ignoring them as we did in the past. Of course, do not use them!
* Clean up the warnings related to document structure.Ingo Schwarze2014-07-011-18/+18
| | | | | | | | | * Hierarchical naming of the related enum mandocerr items. * Mention the offending macro, section title, or string. While here, improve some wordings: * Descriptive instead of imperative style. * Uniform style for "missing" and "skipping". * Where applicable, mention the fallback used.
* garbage collect two unused enum mandocerr itemsIngo Schwarze2014-06-301-10/+6
| | | | and fix a couple of comments while here
* Improve messages related to the roff(7) .so request.Ingo Schwarze2014-06-251-2/+3
| | | | | | | | | | | | | In all these messages, show the filename argument that was passed to the .so request. In case of failure, show an additional message reporting the file and the line number where the failing request was found. The existing message reporting the reason for the failure - for example, "Permission denied" - is left in place, unchanged. Inspired by a question asked by Nick@ after he saw the confusing old messages that used to be emitted in this area.
* As suggested by jmc@, only include line and column numbers into messagesIngo Schwarze2014-06-201-2/+3
| | | | | | | | | | | | | | when they are meaningful, to avoid confusing stuff like this: $ mandoc /dev/null mandoc: /dev/null:0:1: FATAL: not a manual Instead, just say: mandoc: /dev/null: FATAL: not a manual Another example this applies to is documents having a prologue, but lacking a body. Do not throw a FATAL error for these; instead, issue a WARNING and show the empty document, in the man(7) case with the same amount of blank lines as groff does. Also downgrade mdoc(7) documents having content before the first .Sh from FATAL to WARNING.
* Start systematic improvements of error reporting.Ingo Schwarze2014-06-201-11/+11
| | | | | | | | | | | So far, this covers all WARNINGs related to the prologue. 1) hierarchical naming of MANDOCERR_* constants 2) mention the macro name in messages where that adds clarity 3) add one missing MANDOCERR_DATE_MISSING msg 4) fix the wording of one message related to the man(7) prologue Started on the plane back from Ottawa.
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-6/+6
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* Allow leading and trailing vertical lines,Ingo Schwarze2014-03-281-1/+2
| | | | | | | 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 Schwarze2014-03-231-7/+2
| | | | | | | 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 Schwarze2014-03-191-2/+2
| | | | | | 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 Schwarze2014-03-191-11/+7
| | | | | | | | 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 Schwarze2014-01-221-1/+2
| | | | | | | 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 Schwarze2014-01-051-2/+2
| | | | | | | | | | | | | | | 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 Schwarze2014-01-021-2/+10
| | | | | | 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 Schwarze2013-12-301-3/+2
| | | | | 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 Schwarze2013-10-051-2/+3
| | | | | | | | - 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 Schwarze2013-09-161-2/+2
| | | | | | | | | | 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 Schwarze2013-08-081-1/+2
| | | | | 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 Schwarze2013-07-131-2/+3
| | | | | | | | | | 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 Schwarze2013-05-311-3/+3
| | | | | | | 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 Schwarze2012-11-191-1/+3
| | | | Problem reported by jmc@, thanks.
* Warn about unknown volume or arch in Dt macro arguments;Ingo Schwarze2012-11-161-1/+2
| | | | patch written by Nicolas Joly <njoly at pasteur dot fr>.
* Fix handling of paragraph macros inside lists:Ingo Schwarze2012-07-181-1/+2
| | | | | | | * 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 Schwarze2012-07-121-2/+2
| | | | | | | | | | 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 Schwarze2012-05-311-2/+3
| | | | | | | | | | | | | | | | | | 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 Schwarze2012-05-271-10/+3
| | | | | | | | | | | | | | | | 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 Schwarze2012-05-271-3/+3
| | | | | | | | | | 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@

* When the HEAD scope of .TP is broken by another block macro,Ingo Schwarze2011-11-071-2/+1
| | | | | | | | 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 Dzonsons2011-10-061-17/+18
| | | | | | | | | | | | | | 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.

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.
