* Cleanup, minus 15 LOC, no functional change:Ingo Schwarze2018-12-311-2/+0
| | | | | | | | | Simplify the way the man(7) and mdoc(7) validators are called. Reset the parser state with a common function before calling them. There is no need to again reset the parser state afterwards, the parsers are no longer used after validation. This allows getting rid of man_node_validate() and mdoc_node_validate() as separate functions.
* Cleanup, no functional change:Ingo Schwarze2018-12-301-0/+4
| | | | | | | | | | | | | | The struct roff_man used to be a bad mixture of internal parser state and public parsing results. Move the public results to the parsing result struct roff_meta, which is already public. Move the rest of struct roff_man to the parser-internal header roff_int.h. Since the validators need access to the parser state, call them from the top level parser during mparse_result() rather than from the main programs, also reducing code duplication. This keeps parser internal state out of thee main programs (five in mandoc portable) and out of eight formatters.
* Rename mandoc_getarg() to roff_getarg() and pass it the roff parserIngo Schwarze2018-12-211-0/+1
| | | | | | | | | | | | | | | | | | struct as an argument such that after copy-in, it can call roff_expand() once again, which used to be called roff_res() before this. This fixes a subtle low-level roff(7) parsing bug reported by Fabio Scotoni <fabio at esse dot ch> in the 4.4BSD-Lite2 mdoc.samples(7) manual page, because that page used an escaped escape sequence in a macro argument. To expand escaped escape sequences in quoted mdoc(7) arguments, too, stop bypassing the call to roff_getarg() in mdoc_argv.c, function args() for this case. This does not solve the case of escaped escape sequences in quoted .Bl -column phrases yet. Because roff_expand() can make the string longer, roff_getarg() can no longer operate in-place but needs to malloc(3) the returned string. In the high-level parsers, free(3) that string after processing it.
* Clean up the validation of .Pp, .PP, .sp, and .br. Make sure allIngo Schwarze2018-12-041-1/+0
| | | | | | | | | | | | | | combinations are handled, and are handled in a systematic manner. This resolves some erratic duplicate handling, handles a number of missing cases, and improves diagnostics in various respects. Move validation of .br and .sp to the roff validation module rather than doing that twice in the mdoc and man validation modules. Move the node relinking function to the roff library where it belongs. In validation functions, only look at the node itself, at previous nodes, and at descendants, not at following nodes or ancestors, such that only nodes are inspected which are already validated.
* Remove more pointer arithmetic passing via regions outside the arrayIngo Schwarze2018-08-171-4/+2
| | | | | that is undefined according to the C standard. Robert Elz <kre at munnari dot oz dot au> pointed out i wasn't quite done yet.
* Macro argument quoting does not prevent recognition of punctuationIngo Schwarze2017-05-301-1/+0
| | | | | | | | | | | and of called macros. This bug affects almost all macros, and fixing it simplifies the code. It is amazing that the bogus ARGS_QWORD feature got implemented in the first place, and then carrier along for more than eight years without anybody ever noticing that it was pointless. Reported by Leah Neukirchen <leah at vuxu dot org>, found on Void Linux.
* Parser unification: use nice ohashes for all three request and macro tables;Ingo Schwarze2017-04-291-1/+0
| | | | no functional change, minus two source files, minus 200 lines of code.
* Continue parser unification:Ingo Schwarze2017-04-241-10/+11
| | | | | | | | * Make enum rofft an internal interface as enum roff_tok in "roff.h". * Represent mdoc and man macros in enum roff_tok. * Make TOKEN_NONE a proper enum value and use it throughout. * Put the prologue macros first in the macro tables. * Unify mdoc_macroname[] and man_macroname[] into roff_name[].
* Remove the ENDBODY_NOSPACE flag, simplifying the code.Ingo Schwarze2017-02-161-1/+1
| | | | | | | | Comparing to groff output, it appears that all cases where it was used and made a difference actually require the opposite, ENDBODY_SPACE. I have no idea why i added it back in 2010; maybe to compensate for some other bug that has long been fixed.
* In private header files, __BEGIN_DECLS and __END_DECLS are pointless.Ingo Schwarze2015-11-071-3/+0
| | | | | | | | | | | | Because these work slightly differently on different systems, they are becoming a maintenance burden in the portable version, so delete them. Besides, one of the chief design goals of the mandoc toolbox is to make sure that nothing related to documentation requires C++. Consequently, linking mandoc against any kind of C++ program would defeat the purpose and is not supported. I don't understand why kristaps@ added them in the first place.
* In order to become able to generate syntax tree nodes on the roff(7)Ingo Schwarze2015-10-201-1/+5
| | | | | | | | level, validation must be separated from parsing and rewinding. This first big step moves calling of the mdoc(7) post_*() functions out of the parser loop into their own mdoc_validate() pass, while using a new mdoc_state() module to make syntax tree state handling available to both the parser loop and the validation pass.
* Very tricky diff to fix macro interpretation and spacing around tabsIngo Schwarze2015-10-171-3/+1
| | | | | | | | | | | | | | in .Bl -column; it took me more than a day to get this right. Triggered by a loosely related bug report from tim@. The lesson for you is: Use .Ta macros in .Bl -column, avoid tabs, or you are in for surprises: The last word before a tab is not interpreted as a macro (unless there is a blank in between), the first word after a tab isn't either (unless there is a blank in between), and a blank after a tab causes a leading blank in the respective output cell. Yes, "blank", "tab", "blank tab" and "tab blank" all have different semantics; if you write code relying on that, good luck maintaining it afterwards...

* Unify some node handling functions that use TOKEN_NONE.Ingo Schwarze2015-04-191-5/+0
| | | | | | | | * mdoc_word_alloc(), man_word_alloc() -> roff_word_alloc() * mdoc_word_append(), man_word_append() -> roff_word_append() * mdoc_addspan(), man_addspan() -> roff_addtbl() * mdoc_addeqn(), man_addeqn() -> roff_addeqn() Minus 50 lines of code, no functional change.
* Unify node handling functions:Ingo Schwarze2015-04-191-2/+0
| | | | | | | | | | | * node_alloc() for mdoc and man_node_alloc() -> roff_node_alloc() * node_append() for mdoc and man_node_append() -> roff_node_append() * mdoc_head_alloc() and man_head_alloc() -> roff_head_alloc() * mdoc_body_alloc() and man_body_alloc() -> roff_body_alloc() * mdoc_node_unlink() and man_node_unlink() -> roff_node_unlink() * mdoc_node_free() and man_node_free() -> roff_node_free() * mdoc_node_delete() and man_node_delete() -> roff_node_delete() Minus 130 lines of code, no functional change.
* Unify {mdoc,man}_{alloc,reset,free}() into roff_man_{alloc,reset,free}().Ingo Schwarze2015-04-181-1/+0
| | | | | Minus 80 lines of code, no functional change. Written on the train from Koeln to Wolfsburg returning from p2k15.
* Move mdoc_hash_init() and man_hash_init() to libmandoc.hIngo Schwarze2015-04-181-1/+0
| | | | | and call them from mparse_alloc() and choose_parser(), preparing unified allocation of struct roff_man.
* Replace the structs mdoc and man by a unified struct roff_man.Ingo Schwarze2015-04-181-46/+16
| | | | | Almost completely mechanical, no functional change. Written on the train from Exeter to London returning from p2k15.
* Third step towards parser unification:Ingo Schwarze2015-04-021-1/+1
| | | | | Replace struct mdoc_meta and struct man_meta by a unified struct roff_meta. Written of the train from London to Exeter on the way to p2k15.
* Second step towards parser unification:Ingo Schwarze2015-04-021-23/+23
| | | | | | | | | Replace struct mdoc_node and struct man_node by a unified struct roff_node. To be able to use the tok member for both mdoc(7) and man(7) without defining all the macros in roff.h, sacrifice a tiny bit of type safety and make tok an int rather than an enum. Almost mechanical, no functional change. Written on the Eurostar from Bruxelles to London on the way to p2k15.
* Get rid of all calls to rew_sub() in blk_exp_close(); only ten callsIngo Schwarze2015-02-021-1/+1
| | | | | | remain in other functions. As a bonus, this fixes an assertion failure jsg@ found some time ago with afl (test case 982) and improves minor details in error reporting.
* remove unneccessary inclusion protection; patch from deraadt@Ingo Schwarze2014-12-011-4/+0

* Provide a helper function macro_or_word() and use it to prune theIngo Schwarze2014-11-291-2/+0
| | | | | | | | | | same chunk of argument parsing code out of five of the eight callback functions. The other three have too much special handling to participate. As a bonus, let lookup() and mdoc_args() deal with line macros and retire the lookup_raw() helper and the mdoc_zargs() internal interface function. No functional change, minus 40 lines of code.
* Fold the loop around mdoc_argv() into the function itself,Ingo Schwarze2014-11-281-8/+1
| | | | | | it was the same in all four cases. As a bonus, get rid of one enum type that was used for internal communication. No functional change, minus 40 lines of code.
* Retire support for CSRG supplementary document titles. These areIngo Schwarze2014-11-281-1/+0
| | | | | long obsolete and were never written in mdoc(7) in the first place. Removes 100 lines from source files.
* Simplify by making the mdoc parser callbacks void, and some cleanup;Ingo Schwarze2014-11-281-3/+3
| | | | no functional change, minus 50 lines of code.
* Simplify the code by making various mdoc parser helper functions void.Ingo Schwarze2014-11-281-9/+8
| | | | No functional change, minus 130 lines of code.
* Simplify code by making mdoc validation handlers void.Ingo Schwarze2014-11-281-2/+2
| | | | No functional change, minus 90 lines of code.
* Multiple fixes with respect to in-line macros:Ingo Schwarze2014-11-171-1/+2
| | | | | | | | | | * .No selects the default font; relevant e.g. in .Bf blocks * no need to force empty .Li elements * closing delimiters as leading macro arguments do not suppress space * opening delimiters at the end of a macro line do not suppress space * correctly handle delimiter spacing in -Tman As a side effect, these fixes let mandoc warn about empty .No macros as requested by bentley@.
* demacrify: get rid of man_nmsg(), man_pmsg(), mdoc_nmsg(), mdoc_pmsg()Ingo Schwarze2014-08-011-4/+0

* garbage collect three unused global flags; no functional changeIngo Schwarze2014-07-301-1/+0
|
* mark defos as const; nobody needs to change it,Ingo Schwarze2014-07-091-1/+1
| | | | and it is occasionally useful to be able to pass literal strings
* Implement the obsolete macros .En .Es .Fr .Ot for backward compatibility,Ingo Schwarze2014-07-021-0/+1
| | | | | since this is hardly more complicated than explicitly ignoring them as we did in the past. Of course, do not use them!
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-4/+4
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* Add an option -Q (quick) to mandocdb(8)Ingo Schwarze2014-01-051-0/+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.
* There are three kinds of input lines: text lines, macros takingIngo Schwarze2013-10-211-2/+6
| | | | | | | | | | | | | | | positional arguments (like Dt Fn Xr) and macros taking text as arguments (like Nd Sh Em %T An). In the past, even the latter put each word of their arguments into its own MDOC_TEXT node; instead, concatenate arguments unless delimiters, keeps or spacing mode prevent that. Regarding mandoc(1), this is internal refactoring, no output change intended. Regarding mandocdb(8), this fixes yet another regression introduced when switching from DB to SQLite: The ability to search for strings crossing word boundaries was lost and is hereby restored. At the same time, database sizes and build times are both reduced by a bit more than 5% each.
* Cleanup naming of local variables to make the code easier on the eye:Ingo Schwarze2012-11-171-8/+7
| | | | | | | | 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 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
* Support -Ios='OpenBSD 5.1' to override uname(3) as the source of theIngo Schwarze2012-05-271-0/+1
| | | | | | | | | | 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@
* In man(7), when no explicit volume name is given, use the defaultIngo Schwarze2011-12-021-1/+0
| | | | | | | | | | | | volume name for the respective manual section, just like in mdoc(7). This gives us nicer page headers for cvs(1), lynx(1), tic(1), mkhybrid(8), and many curses(3) manuals. ok kristaps@ To not break compatibility, i wrote a corresponding patch for GNU troff which Werner Lemberg accepted upstream at rev. 1.65 of: http://cvs.savannah.gnu.org/viewvc/groff/tmac/an-old.tmac?root=groff

* Make `struct roff' be passed into libmdoc and libman upon creation.Kristaps Dzonsons2011-07-181-0/+1
| | | | | This is required for supporting in-line equations. While here, push registers properly into roff and add an set/get/mod interface.
* Clean up parsing of delimiters in -mdoc. First, remove the "dowarn"Kristaps Dzonsons2011-04-191-7/+1
| | | | | | | | variable from mandoc_getarg() so that it prints the warning every time. Then, remove the warning from args_checkpunct(). This way, warnings are being posted at the correct time. This makes the flag argument to mdoc_zargs() superfluous, so make it be zero when it's invoked. Finally, move the args() flags into mdoc_argv.c and make them enums.
* Get mdoc_argv.c ready to use [some of] mandoc_getarg() by giving saidKristaps Dzonsons2011-04-171-10/+10

* libmdoc.h and libman.h were including mdoc.h and man.h, respectively.Kristaps Dzonsons2011-03-221-2/+0
| | | | | Don't have them do that (includes in header files = faugh), and have individual files directly include these files.
* mdoc_argn_free is only used local to mdoc_argv.c, so make it static.Kristaps Dzonsons2011-03-221-1/+0

* Move mandoc_isdelim() back into libmdoc.h. This fixes an unreportedKristaps Dzonsons2011-03-221-0/+20
| | | | | | | | | 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 Dzonsons2011-03-201-7/+4
| | | | | | | | | 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 Dzonsons2011-03-171-1/+1
| | | | | make mdoc_vmsg not return an int. libmdoc is now completely clean of return-value checks from the message subsystem.
