* Unify mdoc_deroff() and man_deroff() into a common function deroff().Ingo Schwarze2015-04-231-47/+1
| | | | | | | | No functional change except that for mdoc(7), it now skips leading escape sequences just like it already did for man(7). Escape sequences rarely occur in mdoc(7) code and if they do, skipping them is an improvement in this context. Minus 30 lines of code.
* Get rid of two empty wrapper functions. No functional change.Ingo Schwarze2015-04-231-8/+1

* Unify trickier node handling functions.Ingo Schwarze2015-04-191-22/+2
| | | | | | | * man_elem_alloc() -> roff_elem_alloc() * man_block_alloc() -> roff_block_alloc() The functions mdoc_elem_alloc() and mdoc_block_alloc() remain for now because they need to do mdoc(7)-specific argument processing.
* Unify some node handling functions that use TOKEN_NONE.Ingo Schwarze2015-04-191-59/+3
| | | | | | | | * 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.
* Decouple the token code for "no request or macro" from the individualIngo Schwarze2015-04-191-11/+11
| | | | | | high-level parsers to allow further unification of functions that only need to recognize this code, but that don't care about different high-level macrosets beyond that.
* Unify node handling functions:Ingo Schwarze2015-04-191-180/+18
| | | | | | | | | | | * 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.
* Delete the wrapper functions mdoc_meta(), man_meta(), mdoc_node(),Ingo Schwarze2015-04-181-15/+1
| | | | | | man_node() from the mandoc(3) semi-public interface and the internal wrapper functions print_mdoc() and print_man() from the HTML formatters. Minus 60 lines of code, no functional change.
* Unify {mdoc,man}_{alloc,reset,free}() into roff_man_{alloc,reset,free}().Ingo Schwarze2015-04-181-63/+1
| | | | | 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 Schwarze2015-04-181-3/+1
| | | | | and call them from mparse_alloc() and choose_parser(), preparing unified allocation of struct roff_man.
* Profit from the unified struct roff_man and reduce the number ofIngo Schwarze2015-04-181-1/+2
| | | | | arguments of mparse_result() by one. No functional change. Written on the ICE Bruxelles-Koeln on the way back from p2k15.
* Replace the structs mdoc and man by a unified struct roff_man.Ingo Schwarze2015-04-181-52/+54
| | | | | Almost completely mechanical, no functional change. Written on the train from Exeter to London returning from p2k15.
* Third step towards parser unification:Ingo Schwarze2015-04-021-4/+4
| | | | | 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 Schwarze2015-04-021-35/+34
| | | | | | | | | 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.
* First step towards parser unification:Ingo Schwarze2015-04-021-31/+32
| | | | | | Replace enum mdoc_type and enum man_type by a unified enum roff_type. Almost mechanical, no functional change. Written on the ICE train from Frankfurt to Bruxelles on the way to p2k15.
* starting a tbl(7) breaks man(7) next-line scope;Ingo Schwarze2015-01-301-59/+66
| | | | triggered by a bug report from jsg@
* Strangely, ignoring the roff(7) .na request was implemented in the man(7)Ingo Schwarze2015-01-241-2/+2
| | | | | parser. Simplify the code by moving it into the roff(7) parser, also making it work for mdoc(7).
* Fatal errors no longer exist.Ingo Schwarze2015-01-151-3/+2
| | | | | | 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.
* mdoc(7) already uses the mandoc(1) -Ios argument in the footer lineIngo Schwarze2014-12-281-2/+4
| | | | | | 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>.
* Simplify by making the eqn and tbl steering functions void;Ingo Schwarze2014-11-281-5/+3
| | | | no functional change, minus 15 lines of code.
* Simplify by making many functions in the man(7) parser void,Ingo Schwarze2014-11-281-118/+70
| | | | and some cleanup; no functional change, minus 70 lines.
* Escape sequences terminate high-level macro names, and when doing so,Ingo Schwarze2014-11-191-7/+22
| | | | | | they are ignored, just in the same way as for request names and for low-level macro names. This also cures a warning in the pod2man(1) preamble.
* Allow the five man(7) font macros to concatenate their line arguments,Ingo Schwarze2014-11-031-1/+16
| | | | | | | the same way the mdoc(7) macros marked MDOC_JOIN do it. In -Thtml, this removes bogus <br/> when the font macros are used in no-fill mode; issue found by jsg@ in the Xcursor(3) SYNOPSIS. As a bonus, this slightly reduces the size of the syntax tree.
* correct the spacing after in-line equationsIngo Schwarze2014-10-201-2/+3
| | | | | that start at the beginning of an input line but end before the end of an input line
* correct spacing before inline equationsIngo Schwarze2014-10-201-1/+3
|
* Simplify by handling empty request lines at the one logical placeIngo Schwarze2014-09-061-8/+1
| | | | | in the roff parser instead of in three other places in other parsers. No functional change.
* Get rid of HAVE_CONFIG_H, it is always defined; idea from libnbcompat.Ingo Schwarze2014-08-101-3/+1
| | | | | | Include <sys/types.h> where needed, it does not belong in config.h. Remove <stdio.h> from config.h; if it is missing somewhere, it should be added, but i cannot find a *.c file where it is missing.
* Simplify man(7) validation:Ingo Schwarze2014-08-011-4/+5
| | | | | | | | | Drop pre-handlers, they were almost unused. Drop the needless complexity of allowing more than one post-handler. This saves one internal interface function, one static function, one private struct definition, sixteen static arrays, and 45 lines of code. No functional change.
* mention requests and macros in more messagesIngo Schwarze2014-08-011-3/+3
|
* garbage collect three unused global flags; no functional changeIngo Schwarze2014-07-301-45/+8
|
* Simplify: replace one global flag by one local variable.Ingo Schwarze2014-07-301-12/+7
| | | | No functional change.
* Clean up ERROR messages related to document structure and macros:Ingo Schwarze2014-07-071-3/+3
| | | | Hierarchical naming and mention macro names in messages.
* Simplify man_unscope(), removing 18 lines of code, that is,Ingo Schwarze2014-07-071-4/+4
| | | | | | removing one function argument, one function definition, three function invocations and two pointless assert()s. No functional change.
* Clean up messages related to plain text and to escape sequences.Ingo Schwarze2014-07-061-4/+7
| | | | | * Mention invalid escape sequences and string names, and fallbacks. * Hierarchical naming.
* Do not segfault in makewhatis -Q if the next .SH after .SH NAMEIngo Schwarze2014-05-071-4/+7
| | | | does not have any arguments. Crash found by nigel@ in kermit(1).
* KNF: case (FOO): -> case FOO:, remove /* LINTED */ and /* ARGSUSED */,Ingo Schwarze2014-04-201-46/+30
| | | | | remove trailing whitespace and blanks before tabs, improve some indenting; no functional change
* Implement the roff(7) .ll (line length) request.Ingo Schwarze2014-03-301-2/+2
| | | | | Found by naddy@ in the textproc/enchant(1) port. Of course, do not use this in new manuals.
* Skip leading escape sequences in man_deroff(). Helps indexing ofIngo Schwarze2014-03-231-4/+11
| | | | some manuals containing overzealous escaping in their NAME section.
* If a man(7) NAME section contains macros, avoid truncated or emptyIngo Schwarze2014-03-231-1/+41
| | | | | | entries for .Nd in mandocdb(8), instead use the macro content recursively. This improves indexing of more than 200 manuals in Xenocara, i.e. more than 15%, in particular GL and some Xkb.
* The files mandoc.c and mandoc.h contained both specialised low-levelIngo Schwarze2014-03-231-1/+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.
* Joerg Sonnenberger contributed copyrightable amounts of text toIngo Schwarze2014-01-061-1/+2
| | | | | | some files. To make it clear that he also put his contributions under the ISC license, with his explicit permission, add his Copyright notice to the relevant files. No code change.
* Add an option -Q (quick) to mandocdb(8)Ingo Schwarze2014-01-051-2/+10
| | | | | | | | | | | | | | | 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.
* Simplify: Remove an unused argument from the mandoc_eos() function.Ingo Schwarze2013-12-311-2/+2
| | | | No functional change.
* Ignore blank lines right after .SH and .SS.Ingo Schwarze2013-11-101-6/+12
| | | | Improves the rendering of gpg(1); issue reported by jca on ports.
* Implement the .UR/.UE block (uniform resource identifier) introduced in theIngo Schwarze2013-10-171-2/+3
| | | | | | | | man-ext macros by Eric S. Raymond, enabled by default in groff_man(7). Usual disclaimer: You don't write new man(7) code, so you are not going to use these, either. Improves e.g. the bzr(1) and etherape(1) manuals. Thanks to naddy@ for bringing these to my attention.
* Cleanup naming of local variables to make the code easier on the eye:Ingo Schwarze2012-11-171-126/+126
| | | | | | | | 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
* Translate blank input lines to .sp just like in mdoc(7),Ingo Schwarze2012-07-141-3/+4
| | | | | | and ignore .sp after .PP. This fixes vertical spacing for blank lines after .PP and for .sp after .PP. OpenBSD rev. man.c 1.68 and man_term.c 1.86
* Add `cc' support.Kristaps Dzonsons2012-06-121-2/+2
| | | | | | | | | | | | | | | This was reported by espie@ and in the TODO. Caveat: `cc' has buggy behaviour when invoked in groff(1) and followed by a line-breaking control character macro, e.g., in a -man doc, .cc | .B foo 'B foo |cc 'B foo will cause groff(1) to behave properly for `.B' but inline the macro definition for `B' when invoked with the line-breaking macro.
* Minimal implementation of .EX and .EE for GNU compatibility.Ingo Schwarze2012-06-021-2/+2
| | | | | Do not use this, it is not portable and only defined in esr's man-ext. For example, sox(1) wants these macros.
* Add support for `OP', one of the extended man macros. This also requiresKristaps Dzonsons2012-01-031-2/+2
| | | | some man(7) changes to accomodate for the an-ext compatibility.
* Correctly handle constructs likeJoerg Sonnenberger2011-11-161-3/+8
