| | | | | | | | between EQ and EN roff blocks. EQN is different from TBL in that data after .EQ is unilaterally considered an equation until an .EN. Thus, there's no need to jump through hoops in having table spans and so on. This is ONLY the parse code framework in libroff. EQN is not yet passed into the backends.

* Initial tbl framework. Parse point is in libroff, which keeps aKristaps Dzonsons2010-12-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | reference to a current tbl parse and routes ALL text into the tbl parse after stripping reserved words and making block-level pre-processing (e.g., `ig'). This is consistent with an analysis of embedded `TS/TE' in manuals with sprinkled -mdoc, roff, and -man macros. Fact of a parse is exposed to main.c by a return value (ROFF_TBL), which will trigger main.c to add a foreign parsed body to the -mdoc or -man parse stream. This interface isn't in yet, but will follow the parse-text functions in both libraries. I put this login in main.c because I don't want libroff calling directly into libmdoc or libman. As a consequence, a parsed row can be pushed directly into any -mdoc or -man context (put a `Bd -literal -offset indent' into a `TE/TS' block to see why this is necessary). It will then absorb formatting cues in the front-ends. A note on naming. I decided on libroff.h instead of tbl.h because this is purely within the roff layer. Separate tbl implementations will need, then, to interface with libroff. This is "how it should be" because tbl is tightly linked with roff in terms of `ds' and other formatting macros, as well as, of course, special characters and other roffisms.
* Merge restructuring of main.c code. This provided by schwarze@ and inspectedKristaps Dzonsons2010-12-011-0/+3
| | | | | | | | carefully by joerg@. Merge roff.h header for compilation's sake (this is not yet implemented in roff.c.). THIS IS A BUGGY CHECK-IN. The manual type is erroneously kept between runs of the compiler. This is a known bug.
* Implement a simple, consistent user interface for error handling.Ingo Schwarze2010-08-201-1/+1
| | | | | | | | | | | | | | | | | We now have sufficient practical experience to know what we want, so this is intended to be final: - provide -Wlevel (warning, error or fatal) to select what you care about - provide -Wstop to stop after parsing a file with warnings you care about - provide consistent exit status codes for those warnings you care about - fully document what warnings, errors and fatal errors mean - remove all other cruft from the user interface, less is more: - remove all -f knobs along with the whole -f option - remove the old -Werror because calling warnings "fatal" is silly - always finish parsing each file, unless fatal errors prevent that This commit also includes a couple of related simplifications behind the scenes regarding error handling. Feedback and OK kristaps@; Joerg Sonnenberger (NetBSD) and Sascha Wildner (DragonFly BSD) agree with the general direction.

| | | | | | | | | functionality and UGLY works quite well thanks to schwarze@'s careful attention. This also backs out function-prototype changes for struct regset, instead stuffing a pointer to the regset directly into struct mdoc/man/roff.
* First step of adding register support. This is inspired by a significantKristaps Dzonsons2010-06-261-2/+2
| | | | | | 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.
* libroff now is aware of which sub-nodes should be interpreted even in aKristaps Dzonsons2010-05-171-1/+1
| | | | | | | | | | conditional-negative context so as to preserve structural integrity. Initial "rules" (deny/allow) are now inherited for future work in evaluating conditionals. Lint-fix noted by Joerg. Added regression tests for zany constructs.
* Allow roff_parseln() to be re-run.Kristaps Dzonsons2010-05-161-4/+6
| | | | | | | | | Allow roff_parseln() to manipulate the line buffer offset. This is used in situations like `.ie n .TH FOO 1' or `.ie n .ie n', where the line buffer offset is recalculated then the roff parser re-run. Fix mdoc_parseln() and man_parseln() to accept the initial line offset. WARNING: backed-out ALL roff macros whilst accomodating for how roff handles multi-line conditionals (in short, re-running the parser).
* Add mandoc.h, which will eventually replace compilers' inner enum errors ↵Kristaps Dzonsons2010-05-151-5/+5
