* Split -Wstyle into -Wstyle and the even lower -Wbase, and addIngo Schwarze2017-06-241-0/+1
| | | | | | | | | | | | | | | -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@.
* Naive implementation of the roff(7) .po (page offset) request.Ingo Schwarze2017-06-141-0/+24
| | | | | | This clearly works when .po is called on the top level, but might not be sophisticated enough if people call .po inside indentation-changing contexts, but i haven't seen that in manual pages (yet :).
* improve rounding rules for scaling unitsIngo Schwarze2017-06-141-1/+1
| | | | in horizontal orientation in the terminal formatter
* implement roff(7) .rj (right justify) requestIngo Schwarze2017-06-141-14/+16

* make the internal a2roffsu() interface more powerful by returningIngo Schwarze2017-06-081-2/+2
| | | | | a pointer to the end of the parsed data, making it easier to parse subsequent bytes
* Prepare the terminal driver for filling multiple columns in parallel,Ingo Schwarze2017-06-071-14/+14
| | | | | | first step: split column data out of the terminal state struct into a new column state struct and use an array of such column state structs. No functional change.
* Minimal implementation of the roff(7) .ce request (center a numberIngo Schwarze2017-06-061-0/+39
| | | | | of input lines without filling). Contrary to groff, high-level macros abort .ce mode for now.
* Implement the roff(7) .mc (right margin character) request.Ingo Schwarze2017-06-041-2/+19
| | | | | | The Tcl/Tk manual pages use this extensively. Delete the TERM_MAXMARGIN hack, it breaks .mc inside .nf; instead, implement a proper TERMP_BRNEVER flag.
* Basic implementation of the roff(7) .ti (temporary indent) request.Ingo Schwarze2017-05-081-0/+42
| | | | Needed by about four dozen ports (thanks to naddy@ for the research).
* Basic implementation of the roff(7) .ta (define tab stops) request.Ingo Schwarze2017-05-071-1/+11
| | | | | | This is the first feature made possible by the parser reorganization. Improves the formatting of the SYNOPSIS in many Xenocara GL manuals. Also important for ports, as reported by many, including naddy@.
* Move .sp to the roff modules. Enough infrastructure is in placeIngo Schwarze2017-05-051-1/+25
| | | | now that this actually saves code: -70 LOC.
* move .ll to the roff modulesIngo Schwarze2017-05-051-1/+10
|
* Move handling of the roff(7) .ft request from the man(7)Ingo Schwarze2017-05-051-1/+29
| | | | | 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/+52
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).
