* Simplify by creating struct roff_node syntax tree nodes for tbl(7)Ingo Schwarze2017-07-081-16/+6
| | | | | | | | | | | | right from roff_parseln() rather than delegating to read.c, similar to what i just did for eqn(7). The interface function roff_span() becomes obsolete and is deleted, the former interface function roff_addtbl() becomes static, the interface functions tbl_read() and tbl_cdata() become void, and minus twelve linus of code. No functional change.
* 1. Eliminate struct eqn, instead use the existing membersIngo Schwarze2017-07-081-8/+3
| | | | | | of struct roff_node which is allocated for each equation anyway. 2. Do not keep a list of equation parsers, one parser is enough. Minus fifty lines of code, no functional change.
* various nits found with mandoc -TlintIngo Schwarze2017-07-041-1/+1

* Basic reporting of .Xrs to manual pages that don't existIngo Schwarze2017-07-011-1/+11
| | | | | | | | | | | | in the base system, inspired by mdoclint(1). We are able to do this because (1) the -mdoc parser, the -Tlint validator, and the man(1) manual page lookup code are all in the same program and (2) the mandoc.db(5) database format allows fast lookup. Feedback from, previous versions tested by, and OK jmc@. A few features will be added to this in the tree, step by step.
* Split -Wstyle into -Wstyle and the even lower -Wbase, and addIngo Schwarze2017-06-241-1/+6
| | | | | | | | | | | | | | | -Wopenbsd and -Wnetbsd to check conventions for the base system of a specific operating system. Mark operating system specific messages with "(OpenBSD)" at the end. Please use just "-Tlint" to check base system manuals (defaulting to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the manuals of portable software projects you maintain that are not part of OpenBSD base, to avoid bogus recommendations about base system conventions that do not apply. Issue originally reported by semarie@, solution using an idea from tedu@, discussed with jmc@ and jca@.
* Move handling of the roff(7) .ft request from the man(7)Ingo Schwarze2017-05-051-1/+2
| | | | | modules to the new roff(7) modules. As a side effect, mdoc(7) now handles .ft, too. Of course, do not use that.
* Start roff formatter modules for HTML and termininal output,Ingo Schwarze2017-05-041-0/+16
| | | | | | | used by both the mdoc and man formatters, with the ultimate goal of reducing code duplication between the two macro formatters. Made possible by the parser unification. Add the first formatting function (for the .br request).
* Parser unification: use nice ohashes for all three request and macro tables;Ingo Schwarze2017-04-291-6/+23
| | | | no functional change, minus two source files, minus 200 lines of code.
* Continue parser unification:Ingo Schwarze2017-04-241-0/+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[].
* delete documentation of some stuff that no longer exists,Ingo Schwarze2017-03-301-5/+5
| | | | mostly about SQLite3; noticed by Jan Stary <hans at stare dor cz>
* update developer documentationIngo Schwarze2016-07-071-84/+92

* Major character table cleanup:Ingo Schwarze2015-10-131-19/+2
| | | | | | | | | | | | | * Use ohash(3) rather than a hand-rolled hash table. * Make the character table static in the chars.c module: There is no need to pass a pointer around, we most certainly never want to use two different character tables concurrently. * No need to keep the characters in a separate file chars.in; that merely encourages downstream porters to mess with them. * Sort the characters to agree with the mandoc_chars(7) manual page. * Specify Unicode codepoints in hex, not decimal (that's the detail that originally triggered this patch). No functional change, minus 100 LOC, and i don't see a performance change.
* Third step towards parser unification:Ingo Schwarze2015-04-021-8/+17
| | | | | 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 Schwarze2015-04-021-14/+17
| | | | | | | | | 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 Schwarze2015-04-021-4/+20
| | | | | | 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.
* Parse the new man.conf(5) "output" directive.Ingo Schwarze2015-03-271-18/+10
| | | | The next step will be to actually use the parsed data.
* ISO C99 explicitly forbids forward references to enum types (6.7.2.3.3.);Ingo Schwarze2014-12-211-4/+7
