New issue 2172 by [email protected]: Get line and column numbers right.
http://code.google.com/p/lilypond/issues/detail?id=2172
Line and column numbers are a total mess in LilyPond.
Guile has its port-line and port-column function 0-based, but since at
least Guilev1 is not utf8-aware, the port-column is likely to be a byte
offset.
LilyPond appears to prefer calculating lines 1-based, and columns 0-based.
What LilyPond calls a column is a character. This corresponds to the
conventions used _inside_ of Emacs. Unfortunately, the command line usage
(see scm/editor.scm) and the GNU compatible error messages count starting
from column 1.
Something which LilyPond happily ignores, making point-and-click
functionality off-by-one.
I think it would make sense to make everything in LilyPond 0-based, and do
the error messages (and calls to text editors, like with point-and-click)
1-based. That Emacs has a different column number concept in the editor as
compared to command line and error messages is not LilyPond's beef since
Emacs properly translates everything coming from those sources.
