Great. I pushed your patch here http://hg.savannah.gnu.org/hgweb/octave/rev/a921b6b772f3.

In the process I found a bug with clf ("reset") and FLTK which I will file separately.

Actually, it can be any toolkit.

I'm re-opening the bug report. With the gnuplot toolkit I get warnings whenever reset is used explicitly.

Sample Code:

Here is another example.

I finally opted for disabling warnings directly in F__get__:

I just noticed that when using gnuplot graphics toolkit we get a warning each time an axes is redrawn:

This is because _gnuplot_draw_axes_ uses the special "__get__" function to obtain hidden properties, which triggers the warning.
It seems to be in one place only so silencing the warning there should be enough. I'll prepare a cset ASAP

Confirmed. I attached a patch in which I disabled the warning as suggested by Markus.

"test imshow" now fails. The actual issue originates in reset where the deprecated properties raise a warning when they are set to their default value (graphics.cc @ line 5001).
Maybe that could be solved by turning that particular warning off at the beginning of the reset function and re-setting it to its previous setting afterwards (@ around line 10228).
Re-opening for this issue.

I pushed your patch here (http://hg.savannah.gnu.org/hgweb/octave/rev/239a9fed80de). Only two small changes, in the .tst file I used '##' rather than '%%' to start comment lines and I found there were some lines that were missing semicolons.

Thanks. Marking as fixed and closing report.

>> How does Matlab handle this?

I don't really know but I am under the impression (see comments in bug #50227) that they first hide the property, eventually announce the change in the release notes (not sure), and remove it later if needed.

I think the addition of a warning is much cle

Deprecation is definitely a nice way to handle obsolescence. How does Matlab handle this? Do they just remove properties, and then people fix their scripts when Matlab produces an error?

We currently don't have a way to deprecate properties as we do for built-in functions.

The attached patch is a first attempt to do so:

  • add a way to mark a property as deprecated (new "d" flag for genprop.awk) so that users are automatically warned when they us it
  • add a .tst file in which we can check that a given property has disappeared from a given version.
