* Using .Nd only makes sense in the NAME section.Ingo Schwarze2017-03-061-2/+10
| | | | | Warn if that macro occurs elsewhere. Triggered by a question from Dag-Erling Smoergrav <des @ FreeBSD>.
* Make the description of -K autodetection easer to understand.Ingo Schwarze2017-03-041-13/+21
| | | | Basic idea suggested by jmc@, OK jmc@.
* new -mdoc -Tmarkdown output mode; OK millert@ reyk@ tb@;Ingo Schwarze2017-03-031-3/+33
| | | | thanks to reyk@ and to Vsevolod at FreeBSD for suggesting it
* In -Ttree output mode, show the BROKEN node flag andIngo Schwarze2017-02-101-2/+15
| | | | provide a -Onoval output option to show the unvalidated tree.
* add missing HISTORY informationIngo Schwarze2017-01-311-2/+15
|
* Add a warning "new sentence, new line".Ingo Schwarze2017-01-281-2/+6
| | | | | | | | | This does not attempt to pinpoint each and every offender, but instead tries very hard to avoid false positives: Currently, there are only two false positives in the whole OpenBSD base system. Only do this in mdoc(7), not in man(7), because manuals written in man(7) typically have much worse problems than this. OK jmc@ on a previous version of the patch
* bug was fixed, delete the BUGS sectionIngo Schwarze2017-01-211-11/+2
|
* show meta data for -Ttree outputIngo Schwarze2017-01-121-3/+11
|
* Introduce flags NODE_NOSRC and NODE_NOPRT for AST nodes.Ingo Schwarze2017-01-101-2/+8
| | | | | | | | | Use them to mark generated nodes and nodes that shall not produce output. Let -Ttree output mode display these new flags. Use NODE_NOSRC for .Ar, .Mt, and .Pa default arguments. Use NODE_NOPRT for .Dd, .Dt, and .Os. These will help to make handling of text production macros more rigorous.
* Stricter validation of the NAME section, in particular:Ingo Schwarze2017-01-081-7/+14
| | | | | | | - require a comma between names - reject all other text nodes - reject all empty Nm below NAME, not only in the leading position - reject Nm after Nd
* sort options list; from jmc@Ingo Schwarze2017-01-061-6/+6
|
* correct spelling error; from jmc@Ingo Schwarze2016-12-281-2/+2
|
* Make the second, section number argument of .Xr mandatory.Ingo Schwarze2016-12-281-2/+9
| | | | | | In fact, we have been requiring it for many years. The only reason to not warn when it was missing was excessive traditionalism - it was optional in 4.4BSD.
* Unify the three stylesheets into a single CSS file.Ingo Schwarze2015-11-051-5/+5
| | | | Many thanks to bentley@ for doing this work.
* If a .Bd block has no arguments at all, drop the block and only keepIngo Schwarze2015-10-301-2/+9
| | | | | its contents. Removing a gratuitious difference to groff output found after a related bug report from krw@.
* improve wording and start a new sentence on a new line; from jmc@Ingo Schwarze2015-10-061-4/+5
|
* briefly document -T tree outputIngo Schwarze2015-09-261-2/+42
|
* Remove the warning about children of .Vt blocks because actually,Ingo Schwarze2015-09-141-9/+2
| | | | | | | .Vt type global_variable No = Dv defined_constant ; is the best way to specify in the SYNOPSIS how a global variable is initialized in the rare case where that matters. Issue noticed by jmc@.
* No need to hardcode /usr/bin/ as the path to more(1); helps portability.Ingo Schwarze2015-04-031-3/+4
| | | | | We don't hardcode the paths to gunzip(1) and cmp(1) either. Discussed with ajacoutot@.
* Escape punctuation characters that have a different meaning in -Tpdf.Ingo Schwarze2015-03-301-3/+3
| | | | | | | | ~, `, and ' get translated to non-ASCII characters by most troff implementations when generating PostScript/PDF output. When the original ASCII character is meant, it needs to be manually escaped. Patch from bentley@.
* refering -> referring; patch from jmc@Ingo Schwarze2015-03-271-2/+2
|
* Modernize documentation by inserting blanks between option lettersIngo Schwarze2015-03-271-58/+55
| | | | | | and option arguments, except for -m because "-m an" and "-m andoc" look just too weird. Of course, the traditional form without the blank will continue to work.
* improve NAME section diagnostics;Ingo Schwarze2015-02-231-10/+20
| | | | confusing messages reported by Jan Stary <hans at stare dot cz>
* clean up post_dt() validation function;Ingo Schwarze2015-02-161-1/+4
| | | | improved diagnostics, minus six lines of code
* Delete the -V option. It serves no purpose but keeps confusing people.Ingo Schwarze2015-02-161-5/+3
| | | | | | | | Keeping track of the versions of installed software is the job of the package manager, not of the individual binaries. If individual binaries include version numbers, that tends to goad people into writing broken configuration tests that inspect version numbers instead of properly testing for features.
* some tweaks to the DIAGNOSTICS sectionIngo Schwarze2015-02-071-14/+11
|
* replace the last legacy generic message type, "argument count wrong",Ingo Schwarze2015-02-061-7/+16
| | | | by more specific messages, improving diagnostics for .cc .tr .Bl -column
* better error reporting regarding .OP .RS .UR .TH argumentsIngo Schwarze2015-02-061-18/+41
|
* better diagnostics about excess arguments to .PD .ft .spIngo Schwarze2015-02-061-1/+5
|
* better error reporting for .br .fi .nf with argumentsIngo Schwarze2015-02-061-2/+5
|
* Delete the legacy generic warning type MANDOCERR_ARGCWARN,Ingo Schwarze2015-02-061-9/+14
| | | | | replacing the last instances by more specific warnings. Improved functionality, minus 50 lines of code.
* better handle .Fo and .Fd without argumentIngo Schwarze2015-02-061-2/+10
| | | | better handle .Fo with more than one argument
* Discard excess head arguments for .Bd .Bl .Bk and delete hwarn_eq0().Ingo Schwarze2015-02-041-8/+11
| | | | | Discard empty .Bk blocks. Improve related diagnostics.
* improve diagnostics regarding arguments of .An .Pp .Lp .br .spIngo Schwarze2015-02-041-2/+14
| | | | in particular, get rid of check_count(..., CHECK_EQ, 0)
* discard .Rs head arguments and improve .Rs diagnosticsIngo Schwarze2015-02-041-1/+10
|
* more specific .Nd diagnostics, allowing to get rid of enum check_lvlIngo Schwarze2015-02-041-2/+8
| | | | and the respective argument of check_count()
* Radical cleanup of COMPATIBILITY sections:Ingo Schwarze2015-01-291-109/+10
| | | | | | | | Remove lots of lies, dozens of irrelevant implementation details, and all references to groff versions older than 1.17. Move relevant information to the pages where it belongs, and out of mandoc(1) in particular. Add some missing general remarks to roff(7), where it fits the character and purpose of the page much better.
* Clean up eqn(7) error handling:Ingo Schwarze2015-01-281-8/+1
| | | | | | | | * When "define" fails, do not drop the whole equation. * Free memory after "undef". * Use standard mandoc error types instead of rolling our own. * Delete obfuscating EQN_MSG() macro. * Add function prototypes while here.
* * Polish tbl(7) error reporting.Ingo Schwarze2015-01-281-14/+39
| | | | | | * Do not print out macro names in tbl(7) data blocks. * Like with GNU tbl, let empty tables cause a blank line. * Avoid producing empty tables in -Tman.
* Rework tbl(7) layout parsing:Ingo Schwarze2015-01-261-3/+41
| | | | | | | | | | | * Continue parsing even if part of the input is invalid. * Do not require whitespace between cell specifications. * Allow tabs as well as blanks between modifiers. * Mark the 'm' modifier as unsupported. * Parse and ignore the 'p' and 'v' modifiers. * Better warning and error messages. * Get rid of a static buffer. Improved functionality but minus 50 lines of code.
* More improvements regarding tbl(7) options.Ingo Schwarze2015-01-261-1/+5
| | | | | | | | | * Treat "allbox" as an alias for "box" for now. * Parse and ignore the GNU tbl "nowarn" option. * For separation, allow spaces, tabs, and commas only. * Mark eqn(7) within tbl(7) as unsupported. * Simplify the option table. * Improve and sort documentation.
* Improve (or rather, rewrite) tbl(7) option parsing.Ingo Schwarze2015-01-261-10/+39
| | | | | | | | | | | | * Allow the layout to start after the semicolon on the options line. * Ignore leading commas. * Option arguments cannot contain closing parentheses. * Avoid needless UNSUPP messages. * Better ERROR reporting. * Delete unused "linesize" field in struct tbl_opts. * No need for static buffers. * Garbage collect one almost empty wrapper function. Improved functionality, but minus 40 lines of code.
* Support .RE with an argument; needed for audio/pms(1).Ingo Schwarze2015-01-241-4/+17
|
* typo fixes from jmc@Ingo Schwarze2015-01-201-2/+2
|
* Split the -Werror message level into -Werror (broken manual, probablyIngo Schwarze2015-01-201-24/+62
| | | | | | | | | | | | | using mandoc is better than using groff) and -Wunsupp (manual using unsupported low-level roff(7) feature, probably using groff is better than using mandoc). Once this feature is complete, it is intended to help porting, making the decision whether to USE_GROFF easier. As a first step, distinguish four classes of roff(7) requests: 1. Supported (currently 24 requests) 2. Currently ignored because unimportant (120) -> no message 3. Ignored for good because insecure (14) -> -Werror 4. Currently unsupported (68) -> these trigger the new -Wunsupp messages
* Fatal errors no longer exist.Ingo Schwarze2015-01-151-53/+41
| | | | | | If a file can be opened, mandoc will produce some output; at worst, the output may be almost empty. Simplifies error handling and frees a message type for future use.
* To get rid of SYSERR entries in enum mandocerr, downgrade problems withIngo Schwarze2015-01-141-9/+13
| | | | | | missing and unreadable files from SYSERR to ERROR. Needed for upcoming work. As a bonus, this minimally simplifies code and documentation.
* mdoc(7) already uses the mandoc(1) -Ios argument in the footer lineIngo Schwarze2014-12-281-2/+5
| | | | | | when .Os has no argument, so do the same for man(7) when .TH has less than four arguments; there is no reason to treat both differently. Issue found following a question from Thomas Klausner <wiz at NetBSD>.
* Ignore mdoc(7) and man(7) macros inside tbl(7) code because theyIngo Schwarze2014-12-161-2/+3
| | | | | would abort the table in an unclean way, causing assertion failures found by jsg@.
* Switch the default output mode from -Tascii to -Tlocale.Ingo Schwarze2014-12-021-7/+9
| | | | | | | | This doesn't change anything unless LC_CTYPE is set, but it helps when running with LC_TYPE=something.UTF-8. OK tedu@ and earlier positive feedback from: bentley@ deraadt@ naddy@ stsp@ uqs@freebsd wiz@netbsd
