I think I still am, but I'm willing to look again. It's easier for me since I just recently wrote a ten-column tabulated list mode application. In my case I do see it clearly because the text of each row in my tabulated list isn't disturbed/confused by any text properties, and I do see an exact duplication of each entire row entry in the property for each column of that property. I expect to publish the software within a day or two, and plan to announce it on the emacs-devel and possibly other lists, at which time you'll be able to see the internals for yourself. The package is planned to be named 'crossword.el' and it brings to emacs the ability to download and play crossword puzzles. =2D- hkp://keys.gnupg.net CA45 09B5 5351 7C11 A9D1 7286 0036 9E45 1595 8BC0

Are you sure the data is actually duplicated and doesn't share
structure? I evaluated that expression over the xref package, and got
the attached string. Nothing looks obviously duplicated, except for the
shared #N= and #N# structures. Also, some of the repetition of shared
structures is probably just due to how string intervals are
represented/printed.
Not that any of this is necessarily optimal, of course, but it's not
immediately alarming to me, either, unless I'm missing something.

In fact, the most common use for the mode is the *Packages* buffer listing, which for me today clocks in at 5211 lines * five columns. In the case of the *Packages* buffer, Perfor= ming (buffer-substring (point) (line-end-position)) on a sampling of lines yields 'PP eval' buffers of length ~500 - ~700 characters. Most of this looks to me to be unnecessary duplicate data. In using the mode for my own purpose, I see that the mode is putting all data of all columns in an entry (row) in each and every single column, ie the size grows exponentially by number of columns (in my personal case, ten columns). This isn't breaking anything, but it looks like bad design unnecessarily hogging memory and filling buffers with cruft. =2D- hkp://keys.gnupg.net CA45 09B5 5351 7C11 A9D1 7286 0036 9E45 1595 8BC0
