tbl is now integrated into mandoc.

tbl is now integrated into mandoc.

[Kristaps Dzonsons]

Hi,

This is just a head's-up that tbl(1) from http://tbl.bsd.lv has been 
fully integrated into mandoc.  This integration consisted of many 
changes to the merged code (the original code-base is now deprecated, as 
I didn't push back the changes).  An illustration:

% ./mandoc -Owidth=68 foo.3

Linux 2.6.32-5-amd64       January 2, 2011      Linux 2.6.32-5-amd64

The input file 'foo.3' is included below.

There are still some elements that need consideration:

  (1) calculating lengths given escapes in input;
  (2) -T[x]html, -Tpdf, and -Tps output.

For now, -Tpdf and -Tps look like crap, and -T[x]html hasn't been done 
at all.  I'm actually not exactly sure how I'm going to get the lines 
done properly in PS or PDF.  -T[x]html, however, shouldn't be too difficult.

Meanwhile, I'm going to try to push some logic down into the code 
regarding (1), then tag out a release so the -Tascii tbl stuff is out in 
the wild.

Take care,

Kristaps

Hi,

A little update.

I've since then pushed the table column/row width calculations into the 
front-end of mandoc.  Now, embedded escapes (such as \f fonts or \s and 
so on) are now correctly handled in terms of spacing widths.

Furthermore, the -Tps and -Tpdf output now look slightly better, as 
ruling widths are now assigned from the underlying output engine 
calculations (glyph widths vs. character count).

I'm going to tweak it some more, check it against the existing tbl 
corpus (as suggested by schwarze@), then tag out a release.

Enjoy,

Kristaps
