* An implementation of `tr'. This routes allocations of TEXT nodesKristaps Dzonsons2011-07-281-6/+17
| | | | | | | through libroff, which does the appropriate translations of `tr'. This is SLOW: it uses the backend of `ds' and `de', which is a simple linear list. However, unlike `ds' and `de', it iterates over EACH CHARACTER of the entire file looking for replacements.
* Have conditional closure for both text and macro lines call through toKristaps Dzonsons2011-05-241-9/+14
| | | | | | ccond(). Fix the text handler to behave like the macro handler regarding escaped \}. Make \} actually become a zero-width space, too, and clean up the documentation in this regard.
* No code change: fixing spelling errors. From a patch by uqs@. Thanks!Kristaps Dzonsons2011-04-301-3/+3

* Add stub for eqn.7 manual and flip it on. Also note COMPATIBILITY issueKristaps Dzonsons2011-02-091-2/+25
| | | | of how we considered .TS (etc.) macros and how the preprocessors do.
* Ignore .ns (no-space mode), .ps (change point size), .ta (tab control)Ingo Schwarze2011-01-251-1/+15
| | | | | | for now. All of these just cause a bit too much or too little whitespace, but no serious formatting problems. Triggered by reports from brad@.
* As noticed by deraadt@, it goes without saying that text filesIngo Schwarze2011-01-251-6/+2
| | | | | | on a UNIX system use UNIX conventions, and UNIX tools working on them expect that. ok jmc@
* Better explain roff(7) macro argument quoting;Ingo Schwarze2011-01-241-8/+37
| | | | ok jmc@.
* Moved table stuff from roff.7 into the new tbl.7 (suggested by Jason McIntyre).Kristaps Dzonsons2011-01-041-203/+6
| | | | Added cross-links to tbl.7 from other manuals.
* Support `T{' and `T}' data blocks. When a standalone `T{' isKristaps Dzonsons2011-01-041-1/+6
| | | | | | | encountered as a line's last data cell, move into TBL_PART_CDATA mode whilst leaving the cell's designation as TBL_DATA_NONE. When new data arrives that's not a standalone `T}', append it to the cell contends. Close out and warn appropriately.
* Fix to make horizontal spanners in the layout be properly printed.Kristaps Dzonsons2011-01-041-23/+50
| | | | | | | mandoc also now warns (so does tbl(1)) if a horizontal spanner is specified along with data. While here, fix up some documentation and uncomment the tbl reference.
* Switch on the `TS' documentation in roff.7. As per off-line discussion,Kristaps Dzonsons2011-01-031-128/+176
| | | | | | | | this may be moved to tbl.7, but for the time being, keep it in the document as it's developed. Also note that my handling of horizontal rules in layouts needs some work.
* Update (still-commented) manual bits for tbl.Kristaps Dzonsons2010-12-291-1/+87
| | | | | Also removed lots of superfluous switch cases by using tolower() and handling only the lowercase keys.
* Initial documentation for TBL, which for the time being is commented-out.Kristaps Dzonsons2010-12-291-2/+48

* Sync to the installed version in OpenBSD, excluding .ft documentation:Ingo Schwarze2010-12-181-90/+140
| | | | | | Be more careful to not confuse requests, macros and escape sequences. Add more info at various places, including new SEE ALSO and HISTORY sections. OK jmc@ kristaps@
* Abort endless loops during roff macro and string expansion.Ingo Schwarze2010-12-101-2/+8
| | | | | | For now, use the simplest conceivable approach, like groff does: Just a fixed, ugly input stack limit. "check it in" kristaps@
* Import changes by schwarze@ and Jason McIntyre into manuals. These areKristaps Dzonsons2010-12-061-84/+272
| | | | | | | | | | for the new libroff macros, the new libman macros, and for the sake of general clarity. Note that `ft' documentation is NOT included, as I've kept it in -man: it's highly confusing to have it in roff.7 when it's not implemented for both -man and -mdoc, as at least in theory, roff.7 should include only macros recognised by BOTH formats.
* Fix `ds' handling. This was stripping characters from "val", when theKristaps Dzonsons2010-07-271-2/+11
| | | | | | syntax of `ds' is such that ALL text following the first non-space/non-double-quote is part of the value. This also fixes the warning of *(string++) = NULL report by kristaps@ and joerg@.
* Re-constitution of `ds' symbol processing. First, push theKristaps Dzonsons2010-07-071-7/+16
| | | | | | | | | roff_getstr() family of functions into roff.c with the "first_string" directly in struct roff. Second, pre-process each line for reserved words in libroff, splicing and re-running a line if it has one (this allows defined symbols to be macros). Remove term.c's invocation of the roff_getstrn() function. Removed function documentation in roff.3 and added roff.7 `ds' documentation.
* Assert my copyright, making it explicit that i'm granting the same licenseIngo Schwarze2010-07-041-2/+3
| | | | | on those parts of the code and text that i have written as Kristaps is. "fine with me" kristaps@
* Allow registers to be unset. Implement and document the `.nr nS val'.Kristaps Dzonsons2010-06-271-4/+7
|
* First step of adding register support. This is inspired by a significantKristaps Dzonsons2010-06-261-2/+36
| | | | | | patch by schwarze@. This commit adds support to libroff parsing `nr' into register set defined in regs.h. This will propogate into libmdoc and libman in later commits.
* Fix adding some minimal intelligence to conditional parser. See roff.7Kristaps Dzonsons2010-06-101-4/+15
| | | | | | | | | | for what's supported. This simplified the roff_cond() function quite nicely. From a bug report by uqs@. Added regression test based on bug-report example by uqs@. Also added ROFF_DEBUG to see what the hell the parser is actually doing. Obviously turned off by default.
* Noted that \} collapses into a zero-width space on the front-end.Kristaps Dzonsons2010-06-011-3/+5

* recognize ".if n" as true;Ingo Schwarze2010-05-241-3/+11
| | | | | | nothing fancy yet, no negation, no grammer, just that one letter; from OpenBSD; "looks fine" kristaps@
* provide stubs to ignore .ds, .rm and .tr,Ingo Schwarze2010-05-241-2/+20
| | | | | | which occur in the standard pod2man preamble; from OpenBSD; "sounds good" joerg@, "can be checked in" kristaps@
* Documented ie/el.Kristaps Dzonsons2010-05-171-1/+25
| | | | | Installing roff.7 and added it to index.sgml. Small fix for `D1' and `Bd' in -Thtml.
* Full support for ie/el. This completes the initial roff support.Kristaps Dzonsons2010-05-171-1/+6
| | | | | Added test files for ie/el. Using `if 0' as a baseline for "false" roff instructions instead of `if t'.
* libroff now intelligently throws away `am', `ami', `am1', `de', `dei',Kristaps Dzonsons2010-05-171-5/+53
| | | | and `de1'. This is also documented in roff.7.
* `ig' support in all its glory. TryKristaps Dzonsons2010-05-161-6/+66
| | | | | | | | | | | | | | | | | | .ig ig asdf .ig fdsa .. or .ig if asdf .if n \ foo for a laugh. It all works. Lots of regression tests supporting this and documentation for the same.
* Regression tests in place for `.if' in libroff.Kristaps Dzonsons2010-05-161-0/+128
Check against some strange `.if' constructs I missed. Added initial roff.7 manual.
