Hi Stéphane, hi Samuel, hi all,

The idea behind SCIHOME is to have a version specific directory to 
avoid any issues when upgrading from Scilab versions to Scilab 
versions ; IMHO implementing an upgrade for files stored into this 
directory is for me a non-sense ; the upgrade could be done manually 
(as Samuel described) for the few users that copy the files between 
SCIHOMEs.




IMHO, having a separate SCIHOME directory for each scilab version is fine.



I should have written: this is /definitely/ fine, because it allows to 
install and use several Scilab versions on the same computer. And this 
is a very nice Scilab feature.

IMHO, having a separate SCIHOME directory for each scilab version is fine.
This does not necessarily demand to initialize SCIHOME configuration 
files with "factory files" shipped with the release, at the first run, 
as it is currently done.


This initialization could be done with configuration files of a previous 
most recent Scilab release, provided that configuration files are tagged 
with the scilab version that generated (or upgraded) them as proposed by 
Stephane.

This would improve the continuity of usage.
However, detecting a previous version on the same computer is not so 
obvious.


Currently, scilab user preferences are not extremely numerous, and as 
long as scilab releases won't be more frequent, resetting preferences by 
hand for each release is feasable and not blocking.
But for softwares and freewares that propose frequent upgrades, handling 
the copy or upgrade of configuration files in an automatic way is just 
mandatory.


Samuel

PS: by the way, i thing that, as a general rule, tagging a generated 
file with the (name and) version of the software that generated it is 
wise and dramatically improves files backward compatibility. This could 
be done as well for .scg files (i don't thing they are tagged), .zcos 
files (may be they already are), . dat ones (from save()), etc.

Hi,

The version of Scilab which generated the configuration.xml should be contained 
in some attribute of the top level element, i.e.



This would allow to trigger a proper upgrade of the file when the Scilab 
version differs or a regeneration if the file cannot be upgraded.

Hello Stefan,

This kind of error might arise when the content of the SCIHOME directory of a 
previous scilab version is copied into the SCIHOME of the current 6.1.1 
version, for instance to avoid respecifying all users preferences.
Unfortunately, when the template of some configuration file is changed from one 
version to the next one, the file must be regenerated.

The issue should be fixed either by deleting the SCIHOME/configuration.xml 
file, and regenerating it automatically from scratch (quit Scilab and rerun it),
or by editing it and changing or adding the line just before the  
one, for instance with
