Revision 1.4, Sun May 23 22:45:01 2010 UTC (14 years ago) by schwarze
Branch: MAIN
Changes since 1.3: +2 -1 lines 

Unified error and warning message system for all of mandoc,
featuring three message levels, as agreed during the mandoc hackathon:
* FATAL parser failure, cannot produce any output from this input file:
  eventually, we hope to convert most of these to ERRORs.
* ERROR, meaning mandoc cannot cope fully with the input syntax and will
  probably lose information or produce structurally garbled output;
  it will try to produce output anyway but exit non-zero at the end,
  which is eventually intended to make the ports infrastructure happy.
* WARNING, meaning you should clean up the input file, but output
  is probably mostly OK, so this will not cause error-exit at the end.
This commit is mostly just converting the old system to the new one; before
the classification will become really reliable, we must check all messages.

In particular,
* set up a new central message string table in main.c
* drop the old message string tables from man.c and mdoc.c
* get rid of the piece-meal merr enums in libman and libmdoc
* reduce number of error/warning functions from 16 to 6 (still a lot...)

While here, handle a few problems more gracefully:
* allow .Rv and .Ex to work without a prior .Nm
* allow .An to ignore extra arguments
* allow undeclared columns in .Bl -column
