returning empty strings in roff_getstrn() instead of NULL. This caused
maddeningly irregular segfaults in the pod2man preamble for `de IX'.
But only on DEC alpha.
Also integrate the kinda-probably-safe assertion relaxation in term.c,
field-tested by schwarze@. This allows ALL [unpreprocessed] base and
xenocara manuals for all BSD systems to run without segfault.

primarily adds a roff_userdef() function for parsing new defines and
modifies the look-up procedure.
NOTE: there is a bug hidden away in this update that causes an infinite
loop in some pages. The cause is for the moment unknown.

schwarze@ and joerg@ for his comments!
|

Made `rm' be an error (again, OpenBSD...).
|

|

Rename roff_line() -> roff_line_ignore().
|
| | |
|

|
|

fully accomodates for the pod2man standard preamble!

experimental and hasn't been rigorously tested. It's only implemented in
-mdoc for the time being. This is absolutely required for pod2man. It
does, however, make the pod2man preamble be processed in full.

care because pod2man uses this construct.

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.

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@.

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.

on those parts of the code and text that i have written as Kristaps is.

no time for more refinement right now.
In particular, fixes terminfo(3) and mdoc.samples(7).

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.

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.

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.

Fixed flushed-out condition of \} causing subsequent arguments to be
truncated, when in fact the whole line should be passed through (if the
conditional succeeds) to the front-end and the \} ignored there.
Added regression test of this behaviour.

a chain. Good enough for now.

Added test files for ie/el.
Using `if 0' as a baseline for "false" roff instructions instead of `if t'.

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.

and documentation for the same.

Check against some strange `.if' constructs I missed.
Added initial roff.7 manual.

constructs: single-level and multi-level blocks; nested, varied-level
blocks; recalculating buffer (begin) boundaries pushed correctly into
the back-ends, and so on. This will allow, once conditions are turned
on, for things like `.ie n .TH FOO 1' then `.el .Dd Mdocdate'. Read
it and weep.

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 initial roff pre-processor shim, a compiler sitting outside of the other compilers that processes pure roff instructions.
